I just bought this this week and after only one use it's done wonders for my acne! I had a major break out on my chin and after one 15-minute mask it reduced the redness and drew out and healed a few stubborn bumps. It left my skin feeling smooth and clean and I definitely plan on using this once every 3-4 weeks, potentially along with the other Yes To Tomato products. It has a scent to it which I found to be sweet and subtle, nothing too artificial or strong. I would definitely recommend this product if you struggle with acne and redness!
Very hard to get off, didn't really help with anything that it said it was going to, left my skin very sticky for the next couple of hours. Bought it from Ulta, most likely would not buy again.
I love this mask! Yes to is an amazing brand and this mask leaves my skin feeling smooth and very clean. I think this is a very effective mask! You can buy it at target!
I loved this product. It really cleared my pores and refreshed my skin. I've been searching everywhere for a good mask, and this was the first one I was satisfied with.
This charcoal mask is the only one I can use on my easily irritated skin that doesn't make a current breakout worse. The charcoal carefully detoxes while the salicylic acid heals the breakout. And you can't beat the price!
I love this brand so much!! They do not test on animals and every product is extremely high quality! Have loved every one I have tried and love how creative they are with branding with multiple lines for each skin concern
My friend had me try this a few weeks ago and I loved it, took a bit to dry but that was my own fault for applying a tad too much. But my face felt amazinf afterwards.
You feel very refreshed after using this product. It is very useful when needing to feel refreshed and clean. Your face is overall the cleanest it can be after using the product. It was my first time using it and I was wowed! I definitely would buy it again!
I love the consistency of this mask however it did leave my face feeling a bit dry afterwards. Nothing moisturizer can't fix! I recommend for oily to combination skin
Love this product! Not only does it help to clean your skin it exfoliates too. My skin is super sensitive so I'm always surprised when it doesn't react to something new. My skin did not mind this at all. Great product!!!
Q & A
Does this peel off or is it meant to be washed off?

In prison, waking up can be particularly painful. When I was at the SHU (Canada’s Super Max) I would sometimes imagine the scenes in this poem to help me get through the day.
I remember a time, not long ago,
when I once sailed all alone.
When despair was an endless ocean,
and the land of hope was but a dream.
When I would awake at the break of dawn,
and the highest mast I would slowly climb,
to look for as far as my eyes could see,
hoping for an end to my misery.
My sight would return with nothing at all,
my heart would ache and my head would fall.
But in my sadness I would hear a voice,
Saying despair was but a choice.
You’re not alone for God is your friend,
and every hardship must one day end.

I am simulating with LTSpice LTC3864 operated at high duty cycle, with V(output) close to V(input). I'm using the model for LTC3864 provided by LTSpice.
V(input) = 24V
V(output) = 22V
The output voltage is reached correctly.
Then, the pin RUN is pulled Low to disable the Controller.
Instead of pulling GATE to VCC to turn off the external PMOS, GATE keeps the PMOS permanently ON, at 100% duty cycle, and V(output) increases to 24V.
Is this incorrect behavior a bug in the simulation model, or this is the real behavior of the IC?

We all fall for the “trust me, I’m an expert” line once in a while. That’s because the ‘expert’ knows things that we don’t or at least he/she tells us that he does. ‘Experts’ often know how to use tools and techniques to analyse and present information or opinions that the recipients do not, so we are at a disadvantage. The open scientific method relies on some peer review of an analysis and conclusions by other ‘experts’ but the layperson is excluded from this process and just has to trust the ‘experts’.
Most people are familiar with the aphorism “lies, damn lies and statistics”attributed to Disraeli, Bagehot or Balfour (to name a few). In the last couple of days this chart by Reuters using data from the Florida Department of Law Enforcement has been flying around twitter
So what does this chart tell you? At first glance you might judge that gun deaths have fallen since the introduction of the ‘Stand your ground’ law in 2005, after all the graph line makes a steep dip after this point. Now look again. The y-axis scale is one of those Bang & Olufsen things where ‘less is more’ or put simply the scale has been inverted – larger numbers are at the bottom of the scale. Gun deaths actually increased by about 60% after the “Stand your ground” law was enacted. It’s almost beyond belief that anyone who wanted to provide a neutral portrayal of these gun death statistics would create a chart like this.
Business Insider published an article on the relationship between gun deaths and the ‘Stand your ground’ law which included a different presentation of the same data.
This version gives a very different first impression.
Now you don’t have to be an expert statistician to see the trend of the results, it certainly appears that the spike in gun deaths is linked to the enactment of legislation. But maybe it’s more complicated? Perhaps there were other variables that had an influence e.g. a big reduction in gun prices, a robbery at an armaments warehouse, a surge in gang warfare (I’m not suggesting that any of these things did actually happen) or maybe several other factors influenced the spike in gun deaths? Not only do you need to be competent in statistical techniques to analyse the data as it becomes more complex but you also need to be committed to an open and impartial assessment of all of the data as opposed to presenting limited data to validate a hypothesis that supported your (or your organisation’s) agenda.
The more complex the data and the more specialised the knowledge needed to analyse the data, the more most of us are inclined to trust the experts. We don’t really have a choice. However when we trust an expert perhaps we should ask who paid them, what agenda they had and who else has peer reviewed their analysis?
I’m not a statistician (even though I did a stats module in my degree 40 years ago) and you are probably not reading this post for my observations on statistical analysis and presentation. You want some maps, don’t you?
There is always plenty of comment from geographers and cartographers (someone more ‘expert’ than me could explain the difference) about bad maps, atrocious cartography and outright misleading maps. My friend Ken Field has been quite forthright about some examples on his blog Cartonerd particularly on the subject of normalising choropleths, he suggested this article to illustrate a mapping equivalent of the Florida Gun Crime Chart. Back in 2012 the BBC published an article about the geographic distribution of Britain’s medal winners, here is the original map:
Look at this and you might conclude that the most athletic part of the country was London but The Beeb have made the common mistake of not normalising their data. In this case normalising by population would be the best way of presenting the data i.e comparing medals per head of the population of a town or county rather than absolute values. Ken reworked the data and produced these two maps which tell a somewhat different story to the original BBC map.
Ooh look it seems that the highest proportion of Olympic winners by population come from north Wales and Scotland rather than London although in absolute terms the largest number of medals were won by Londoners.
I doubt that the BBC would claim to be cartographic experts. Unfortunately most people don’t know that, they rely upon and trust the BBC as a source of truth, they instinctively accept the maps on the BBC web site as being correct. I would guess that most people see maps on the BBC web site, or any other media or publication, and because of a lack of understanding about how they are made and what might be wrong with them, they assume that the maps are accurate and offer a valid interpretation/presentation of the underlying data.
So the next time someone presents you with a map that seems to ‘prove’ something or tells a story before you accept it you might want to ask a few questions of the author and if you can’t ask those questions at least remember that the author might not be as expert as he claims to be.
When I asked Ken Field for an example to quote in this post, he kindly offered to make a map out of the Florida Gun Crime chart at the top of this post, here it is

1. Field of the Invention
The present invention relates to atmospheric modeling and prediction and more particularly to a system and method employing acoustic sensing for profiling wind, temperature and turbulence.
2. Description of the Related Art
Currently, one of the biggest gaps in global weather monitoring, and therefore in the ability to predict weather, is wind data. Satellites do fairly well at temperature and water vapor content, but can only estimate winds by tracking clouds in photographs. This does not work in clear weather and it does not reveal winds below a cloud deck. Balloon-borne radiosondes measure winds aloft quite well, but only near the places where they are launched, and (usually) only twice a day.
The most useful form of wind monitoring would cover many locations, provide wind speed and direction at all altitudes above each location, and provide the information frequently. Because large transport planes routinely fly over much of the globe, they are a potentially useful tool for making such measurements. Some proposals call for equipping airliners with Doppler lidar or radar capable of measuring winds at many altitudes, even in clear air. However, commercial aircraft operators may be unwilling to accept the cost in weight, power, volume, maintenance, and supplemental FAA certification for carrying lidar or modifying radar.
An alternative is to place ground-based radar wind profilers such as Next Generation Weather Radar (NEXRAD) at many locations. The National Oceanic and Atmospheric Administration (NOAA) has deployed some of these within the US. Regrettably, these profilers are expensive and quite large. Because they are expensive, they are deployed sparsely, so there are important gaps in coverage, e.g. mountainous regions of the US. Because they are also large, they are unsuited to installation on the buoys currently deployed by NOAA at several locations in the oceans. Therefore, weather buoys measure only surface winds, not the higher altitude winds that drive weather.
Another alternative is to place Sound Detection and Ranging (SODAR) profilers at many locations. These devices emit a loud pulse of sound, then measure the weak signal scattered backward by air. The amplitude and Doppler shift of the return signal can reveal winds. The altitude range of SODAR is less than a kilometer as demonstrated by data provided at http://www.sodar.com/about_sodar.htm. Though smaller and cheaper than NEXRAD, the devices are still too large and costly for widespread deployment or for use on buoys. SODAR devices also lead to complaints by people living nearby, since the sound pulse is audible. A related technology is acoustic tomography using time of flight from pulsed active emitters to an array of microphones. This has been used by some foreign groups to estimate winds within a few hundred meters of the ground (see K. Arnold, A. Ziemann, A. Raabe, “Tomographic Monitoring of Wind and Temperature at Different Heights Above the Ground”, acta acustica, Vol. 87 (2001) 703-708), but this method has the same altitude limitations as SODAR.
Another alternative is to launch more radiosondes (weather balloons). These typically get good wind and temperature measurements from the surface to the top of the troposphere. However, each is used only once, so using more of them would increase the $36 million the National Weather Service already spends each year on radiosondes. The cost is increased more if the radiosondes must be released from ships to get ocean coverage: ship operations cost so much that NOAA recently stopped funding a meteorology ship in the North Pacific, even though this action strongly reduced the quality of forecasts on the US west coast.
It is therefore desirable to provide an affordable way to gather frequent wind vector data over oceans or other remote areas without large payloads on aircraft or buoys.
It is also desirable to provide a means for detecting turbulence. Turbulence refers to localized wind variations that are not part of large-scale movement of bodies of air. Turbulence is notoriously hard to detect in clear air aside from direct flight encounters by aircraft. Existing methods mostly have short range in clear air, and are therefore used only near airports where wind shear is a hazard. It is desirable to provide a solution for detecting turbulence over larger areas.
The present invention provides a method for characterizing atmospheric conditions by measuring a varying spectral characteristic of sound at a plurality of intervals from a sound source with the point of measurement and the sound source in relative motion and separated by altitude; in an exemplary embodiment using a ground based microphone to detect sound from an aircraft passing overhead. The spectral characteristic of the sound at each interval is attributed to a path traveled by the sound. A set of simultaneous equations is created for the path at each interval using multiple altitude segments for each path, each segment having a particular vector as a variable on the spectral characteristic. The initial coefficients in each vector are assumed based on predetermined atmospheric models for the associated altitude segment. The resulting calculated vector and the predetermined atmospheric model are iterated to obtain a minimized cost function in a variance analysis to determine the vector for each altitude segment. The vector provides atmospheric properties such as wind speed and direction and temperature for the associated altitude segment.
In various embodiments of the invention, the spectral characteristic measured is arrival time, sound frequency, sound attenuation or the arrival angle. Additionally, by identifying rapidly changing spectral characteristics within one path as identifying turbulence, a plurality of actual paths is calculated based on the vectors and the position of the turbulent region in the actual paths is identified based on the calculated locations of the rapidly changing spectral characteristic.
An exemplary embodiment of a system for characterizing atmospheric conditions according to the present invention provides means for recording acoustic spectral characteristics of sound from an over flying airplane. A computer processor is then employed for analyzing the acoustic spectral characteristics recorded during the airplane overflight and the evolution of the spectral characteristics over time during the overflight. The computer system then relates the evolution of spectral characteristics to determine the most probable distribution of wind and temperature as functions of altitude.
As additional elements of the system, a transmission system reports the flight data of the aircraft sound source including a vector difference of true airspeed and true groundspeed of the airplane for applying the vector difference as a windspeed upper boundary condition in developing the most probable distribution.
The simple components in the measurement system employed by the present invention to measure acoustic data from overflying aircraft as available sources provide an affordable way to gather frequent wind vector data over remote areas without large payloads on aircraft or buoys or complex ground stations.
Additionally, with enhanced data analysis conducted within the existing components of the system, detection and location of turbulence is achieved and can be applied over large areas.
These and other features and advantages of the present invention will be better understood by reference to the following detailed description when considered in connection with the accompanying drawings.
The invention exploits the relationship between sound waves, wind shear, and temperature. In still air, sound emitted directly above a surface-based microphone will travel in a straight line from the sound source to the microphone.
When wind blows, the sound waves are carried along with the air. As shown in
For non-vertical sound paths and winds that vary with altitude, the situation is more complicated. A wind gradient can bend acoustic wave fronts. Sound that follows a non-vertical path is refracted as it traverses a vertical wind gradient. Acoustic wave fronts moving from top layer to bottom layer encounter wind shear. This phenomenon is shown in
The wind speeds are resolvable at various altitudes by considering the usual variation of temperature vs. altitude, i.e. the adiabatic lapse rate of about 2 degrees C. per thousand feet of altitude gained. Under normal conditions, lower altitudes have warmer temperature as represented in
As shown in
With an airplane as the sound source, the consequence of this bent path is that sound waves coming from an airplane far away spend relatively more of their time in low-altitude air, while sound waves from an airplane overhead spend relatively more of their time in high-altitude air. Refraction also limits the range of acoustic detection for airplanes. If the airplane is sufficiently far away in horizontal distance, its sound is totally refracted upward and does not reach the microphone on the surface. Thus, low-altitude delays have relatively more effect on sound from an airplane far away, while high-altitude delays have relatively more effect on sound from an airplane near the zenith.
Applying a method in accordance with the present invention, when an airplane overflies microphone 16, collection of many acoustic samples is accomplished using a computerized data acqusition system 17 having a memory 19 for storage of modeled data, as will be described subsequently, each sample giving slightly different statistical significance to delays at various altitudes. By solving a set of simultaneous equations, values proportional to the delays incurred at each altitude are identified providing an estimate of the winds and temperatures at each altitude. It is assumed for purposes of simplicity in the embodiments discussed herein that the winds only deflect the sound a small distance from its nominal path. Very strong winds cause large deflections and must be analyzed by non-linear methods.
Given the measured arrival time shifts, S, matrix A is inverted and employed to solve the simultaneous equations for the relative speeds of the sounds, D. (The case shown is overdetermined based on the availability of a larger number of equations than variables, allowing the use of statistical methods to get robust estimates for the di values.) From the values of D, the winds are computed.
Measured values of S are used with an initial estimate of A to compute D. D values include the effect of wind, which distorts path shapes and therefore affects A. Thus, a high-precision estimate of winds and temperatures may require iterating estimates of A and D until the solution converges.
The assumptions discussed for the models above imply any wind will delay the arrival of sound waves. However, for sound waves that do not travel vertically, horizontal winds can either delay or accelerate the sound's arrival, depending on the direction of the wind. Winds aligned with the airplane's path will make sound arrive later while the airplane approaches, but will make it arrive earlier while the airplane is getting farther away if the wind is blowing opposite to the aircraft's velocity as represented in
Matrix A values, as shown in exemplary form in
The distance for each layer goes into matrix A at the element corresponding to that layer and that path. We compute values for other paths by starting with other values of θ0.
The plot in
In the numerical model employed in the exemplary embodiment, a ground-level air temperature of 293 Kelvins is assumed. That temperature is defined as having n=1. A still-air lapse rate of −6.5 Kelvins per 1000 meters of altitude gain is modeled, so the temperature at 10,000 meters was 228 Kelvins, or n=1.134. The upper curve (path p=4) started at θ=1.329 radians from vertical near the ground and finished at θ=1.047 radians from vertical above 9000 meters. The lower curve (path p=0) started at θ=0.805 radians and finished at θ=0.710 radians.
It is possible to solve the simultaneous equations with only a series of acoustic measurements, fitting the data to appropriate curves of frequency and amplitude to estimate the time, altitude, and speed of the airplane producing the sound. However, an exemplary embodiment uses measurements of the airplane's location (x, y, z) as a function of time so the source of sound waves at each moment can be estimated more precisely. A further refinement to this exemplary embodiment computes the vector difference between the airplane's true airspeed and its true ground speed. This vector difference equals the wind velocity at the airplane's altitude, as a parameter for defining boundary conditions of the wind estimate. This vector difference is used in prior art to estimate wind speed at aircraft altitude, but is not used in conjunction with any means to estimate winds at intermediate altitudes. Additionally, the exemplary embodiment uses measurements of wind speed at the surface, as a parameter for defining boundary conditions. Finally, the exemplary embodiment uses temperature measurements at the surface, at the airplane, or both, to define boundary conditions for speed-of-sound estimates.
The previous description of an embodiment of the invention relies on measuring arrival times of sound, but the more easily measured quantity is sound frequency. Frequency of the sound arriving at the microphone varies when the amount of delay in arriving sound waves changes from one sample to the next. This changing delay occurs due to variation in the path length through various winds as well as variations due to the aircraft motion.
An alternative embodiment of the invention disclosed herein has modeled this effect using a 10-layer model of the atmosphere. Based on user-selected winds and temperatures at each altitude, the model computes acoustic paths from 10,000 meter altitude to sea level, the emission time and arrival time for sounds emitted by an airplane flying at a user-selected speed, and the apparent Doppler shift for the arriving sounds.
Doppler is also useful for detecting turbulence. The size of turbulence cells is typically a few hundred meters or smaller. An airplane can fly over one in a few seconds at most, so turbulence will delay some sound paths and accelerate others quite nearby. Turbulence will therefore appear as short-period humps and valleys in the Doppler curve, so it can be detected by applying a high-pass filter to the Doppler curve. Because turbulence usually has a vertical wind component, its effect on the delay of near-vertical sound waves is much stronger than the effect of horizontal wind. This makes acoustic Doppler a particularly sensitive means to detect and measure turbulence.
In addition to measuring Doppler shift, the sound waves' arrival angle is measured at the ground for certain embodiments. The arrival angle is steep for a sound path that has been refracted toward the ground and shallow for a path that has been refracted away from the ground. Arrival angle can be measured with a directional microphone, e.g. a phased array as will be described in greater detail subsequently. Arrival angle results for our model are shown in
Another observable quantity used in certain embodiments is acoustic attenuation, i.e. the decrease in sound intensity with distance along the sound's path. For a given distance from airplane to microphone, attenuation is less for shorter (straighter) paths and greater for longer (bent) paths. Attenuation can be estimated either by direct measurement of sound amplitude or by comparison of the acoustic power at high and low frequencies. A detailed mathematical treatment of the energy ratio method is available in Kak and Slaney, Principles of Computerized Tomographic Imaging, IEEE Press, 1988, pp. 154-155.
Attenuation is another sensitive indicator of turbulence. Turbulence is often caused by cells of warmer or cooler air. A convex cell of warm air affects sound the way a concave lens affects light: it makes the waves diverge. That reduces the sound intensity for sound that traverses a warm cell. (The reverse is true: convex cold cells make sound converge. This increases intensity over short distances, but reduces it for points beyond the focal distance.) Turbulence will therefore appear as short-period humps and valleys in the intensity of sound. These can be detected via a high-pass filter.
As shown in
At the receiving microphones, a high-pass filter is applied to the acoustic measurement to enhance the short-term fluctuations. For the embodiment shown, frequency is the measured variable while in alternative embodiments amplitude is measured. The signal is rectified and smoothed to give a low value when the sound traverses non-turbulent air and a high value when the sound traverses turbulent air, as shown by the traces in
To locate that end of the turbulent region, the point where the two paths intersect is computed (for two dimensional (2D) paths, as illustrated in
The procedure described for the exemplary embodiment above is simple, but gives little indication of the intensity of turbulence. In an alternative embodiment, multiple thresholds are used to detect transitions between low and high acoustic fluctuation. The use of multiple thresholds allows the invention to detect and locate regions of strong turbulence (which exceeds the highest threshold) and of moderate or weak turbulence (which exceeds only medium or low thresholds).
In another alternative embodiment, the method of the invention applies various time offsets and time stretching coefficients to delay and stretch the acoustic fluctuation signal at microphone A. This method of the invention adjusts the offset and stretching coefficient to maximize the temporal correlation coefficient of fluctuation signal A with the fluctuation signal at microphone B. Because the correlation is maximized over the whole interval, a more robust alignment of signal A to signal B is obtained than a method based on endpoints alone. This gives a more improved estimate of the location, extent, and strength of the turbulent region based on the increased volume of available data.
With multiple microphones, including some dispersed to the sides of the airplane's ground track, data received is representative of additional geometric orientations with respect to the source of the acoustic spectral data received and improved resolution of the turbulent region can be attained.
Estimates of the wind-induced Doppler shift are more difficult if the frequency of the sounds emitted by the airplane changes in unknown or unpredictable ways. Therefore, the exemplary embodiment uses measurements of the airplane's true airspeed (a source of wind noise), engine turbine rotation rate (a source of machine noise), and/or thrust (an indicator of exhaust turbulence noise), each of which helps refine the estimate of the noise spectrum being produced by the airplane. These measurements from the airplane are downlinked via a communication system such as Aircraft Communication Addressing and Reporting System (ACARS) or Connexion™ by Boeing. An alternative embodiment uses a computational model (either empirical or analytic) of the noise spectrum emitted by the airplane in various downward directions as a function of airspeed, engine speed, and thrust. This helps refine the estimate of the noise spectrum being emitted along the particular path from the airplane to the microphone. Similarly, an embodiment that uses attenuation measurements benefits from measurements of airspeed, turbine speed, and thrust, plus a computational model of noise emitted in each direction from the aircraft.
When the airplane passes nearly straight over the microphone, it is hard to distinguish winds blowing left-to-right (relative to the flight path) from those blowing right-to-left: both wind directions cause the same delay. To resolve this ambiguity, two or more microphones are employed, distributed so that the ground track of a typical aircraft flight will pass at a different distance from each microphone. The use of additional microphones in a small region (for example, a few kilometers on a side) has two additional benefits. First, providing more data points, thereby improving statistical validity of estimated winds, turbulence, and temperatures, and, second, providing data points from sound paths that are horizontally separated, thereby localizing areas where turbulence is detected and providing estimates of horizontal variation in winds and temperatures.
To measure the arrival angle of sound at a microphone, three alternative methods are employed in various embodiments. In a first method, a set of fixed directional microphones, such as cardioid microphones, are oriented in different directions. Then the ratio of acoustic amplitudes measured by the microphones can be indexed to the angular gain of each antenna to indicate the direction of arrival.
In a second method, a phased array of microphones is employed as shown in
A third method employs a single directional microphone that scans (typically in a “coning” pattern) to measure the direction of the strongest signal.
Finally, it must be noted that sounds from an airplane, or even from loud objects on the ground, can propagate upward to a microphone carried by a weather balloon, and these sounds can be used to estimate winds, temperatures, and turbulence at intervening altitudes. This would provide more mid-altitude weather data than current art: today, a balloon only collects mid-altitude data during its ascent. Therefore, an alternative embodiment of the invention provides the microphone aloft with onboard calculation or telemetry of the data to the ground for calculation.
The simplicity of the measurement equipment and the passive nature of using existing sound sources such as aircraft permits the present invention to be used in such scenarios as microphones mounted on buoys for conducting measurements over water. For arrival angle information using models such as those described, for a buoy or other unsteady platform, a device capable of measuring acceleration and/or tilt angles due to the buoy's rocking in waves, and a device capable of computing an appropriate correction to the Doppler shift and arrival angle to cancel the effect of the buoy's motion is employed. The elements of an exemplary buoy mounted system are shown in
The key addition, relative to fixed embodiments, is the inertial measurement unit (IMU) 98 mounted on buoy 100. The aircraft sound arrives at microphones 16A and 16B, which are mounted on the buoy. The microphones and associated electronics measure the frequency, amplitude, and arrival angle of the arriving sound. However, these quantities may be distorted by motion of the buoy in the water. For example, if the buoy is surging to the right when sound arrives from the left, then the measured frequency will be Doppler shifted to a lower frequency than the actual frequency. Likewise, if the buoy tips to the left, then the measured arrival angle for any sound arriving from the left will be higher than the actual arrival angle.
The IMU measures accelerations and rotations of the buoy. The processor 102 uses data from the IMU to correct the measured acoustic parameters, e.g. subtracting the buoy's off-nominal attitude from the measured acoustic arrival angle to compute the actual arrival angle. The processor then transmits the corrected data to users via the radio antenna 104 and associated electronics.
It will be apparent to those skilled in the art that a meteorological buoy usually contains a great deal more equipment than shown here, e.g. thermometers, rain gages, anemometers, GPS receivers, and others. It will also be apparent that the elements of this embodiment can be used to make acoustic measurements using other platforms whose location and attitude may continually change, such as ships, balloons, or flexible towers.
Additionally, the simplicity of the measurement system can be used to provide a low cost network of measurement points with either centralized or distributed computing systems to allow linking data from each of many airplanes to data from microphones that the airplane is currently close to, from among many microphones around the world. Significant geographic coverage for profiling atmospheric conditions can be provided by the network.
Several computational approaches can be used to transform measurements of sound into estimated atmospheric profiles. The approach that is most versatile and most accepted in the meteorology community is based on variational analysis.
where J is the cost to be minimized, xb is a prior estimate of x based on other sensors or models, B is a matrix of weights based on confidence in (and covariance of) various values in xb, H is a “forward model” that transforms a given vector of atmospheric properties into a vector of observable quantities such as sound frequency at various times, y0 is the vector of quantities actually observed, and R is a matrix of weights based on confidence in (and covariance of) various values of Hx and of y0. For example, consider a case derived from the one shown in
An example matrix R is shown in
In an exemplary embodiment, amplitude measurements are employed in addition to frequencies. For an exemplary case, the vector of observations, y0, contains ten elements. Five are measurements of acoustic frequency at times corresponding to paths p=0 to p=4. The other five elements are measurements of acoustic amplitude at the same times. Elements of matrix R are computed by using a nominal atmosphere model (including boundary conditions, if available) and the measured aircraft flight path vs. time. Diagonal elements corresponding to measured frequency are large for measurements where high amplitude is expected. In addition, non-diagonal elements of R add more weight to frequency measurements when the actual amplitude is greater than expected and reduce the weight when amplitude is smaller than expected. This means the actual quality of frequency measurements is used to increase or decrease the importance of each measurement in computing J(x).
An example matrix R for the embodiment described above is shown in
Note that the forward model H used in each case depends on the trajectory of the airplane and the locations of the microphones used for the acoustic measurements. Examples of the forward model, H are present in the previously described data results for
Another example of H is the software that generated
In demonstrated embodiments, H and y include at least two, and preferably three, of frequency, amplitude, and arrival angle.
In most prior art, values in x are defined only as a function of altitude, not horizontal location. This approach to minimize J(x) is called one dimensional variation (1Dvar). It is suitable for measuring broad-scale weather characteristics, such as steady-state winds over relatively smooth terrain.
The present invention can be used to estimate x where values in x are a function of all three spatial coordinates. (An example is a case where x includes an estimate of turbulence at various locations. Turbulence can be quite localized, especially near mountains.) This approach is called three dimensional variation (3Dvar). The use of 1Dvar for meteorological measurements is well known in prior art. The use of 3Dvar for acoustic meteorological measurements is novel to the present invention and created based on the ability of embodiments of the invention to measure acoustic phenomena at multiple locations.
Additionally, the airplane flight path data which may include in addition to location and velocity such elements as weight, engine speed, thrust or other parameters for characterization of the sound emitted is provided 710 and the microphone locations are determined 712 for computation of the forward model H 714. These may include the vector difference in true airspeed and true ground speed of the aircraft as a wind velocity vector that is applied as an upper boundary condition.
R is computed as a weighting matrix 716 based on H and y0 providing the last of the elements of the cost function J discussed above. J(x) is then calculated near x at the initial iteration value, xi, 718. If J(xi) is less than nearby values 720 then a determination is made if Δx is small enough 722 where Δx is the amount by which x is varied about xi. If so, then the solution of J(x) is complete and x=xi 724. If not, then Ax is reduced 726 and J(x) is computed again. If in step 720 J(xi) was not less than nearby values, xi is set to a minimum value xmin and J(x) is computed again at step 720.
Since variational analysis is essentially a gradient descent through the space of J(x), the value of x with the lowest J(x) value is selected as the starting point for the next iteration. xmin is the value of x that gives the lowest cost J(x) when x varies about xi by ±Δx.
It should be noted, for the embodiments described herein, that xi±Δx does not mean simply xi+Δx and xi−Δx. Rather, it means xi varied in the positive and negative direction for each dimension of vector x, with the amount of variation in each direction specified by Δx. Thus, if x has three elements, xi±Δx includes six values of x.
Having now described the invention in detail as required by the patent statutes, those skilled in the art will recognize modifications and substitutions to the specific embodiments disclosed herein. Such modifications are within the scope and intent of the present invention as defined in the following claims.

Nvidia's first desktop graphics processors based on a new 40 nanometer manufacturing process could be available "at the end of September," according a DigiTimes report citing the Chinese-language Commercial Times. The Nvidia GeForce GT220 and GeForce G210 cards should kick things off featuring a GT216 and GT218 GPU respectively, and are expected to directly replace the GT130 and G100 cards to take advantage of the much smaller and energy-efficient process.
DigiTimes claims the graphics firm intended to launch these sooner, but TSMC had initially suffered from poor yields of the 40nm parts. The company has since recovered, however, allowing Nvidia to target holiday sales with their new GPU range. It's not clear if the GeForce GT220 and G210 cards will be available at retail or just as OEM devices for computer builders.
DigiTimes itself says nothing about the new parts in terms of specifications, but a separate report from Electronista claims the GT220 in its current form has 48 visual processing cores, a 615MHz core, and 1GB of 1.3GHz DDR3 memory. The G210 is reportedly much more basic with 16 cores, a 589MHz core clock and 512MB of 1.4GHz DDR2 memory.


IRVINE, Calif. (August 28, 2017) – More than $2 million in Mazda driver development scholarships will be earned this weekend at the season finale for the 2017 Mazda Road to Indy season. Four races for the three Mazda-powered categories take place this Saturday and Sunday at the Watkins Glen International road course. (The Battery Tender Mazda Global MX-5 Cup presented by BFGoodrich Tires series will also compete in two races this Saturday at the Glen. The MX-5 Cup season continues later in the year.)
Championship-winning drivers in the USF2000, Pro Mazda and Indy Lights series will each earn a Mazda scholarship, allowing them to climb up a rung on the open-wheel racing ladder in 2018. Sometimes winning the scholarship can be the difference between continuing or ending a driving career, so the passion and tension is palpable among all of the contenders as they aim to follow in the footsteps of those who have used the MRTI to further their career. (In 2017, 25 of the 33 starting drivers in the Indianapolis 500 had MRTI racing experience!)
Indy Lights presented by Cooper Tires
Kyle Kaiser, 21, from Santa Clara, California, needs only to start the Indy Lights race (Sunday, 10:50 a.m. ET) to secure the championship in his third season in the series. Driving for Juncos Racing, Kaiser has three victories and has extended his points lead with a string of consistent finishes. He will earn a scholarship with a $1 million value, guaranteeing him at least three starts in next year’s Verizon IndyCar Series, including the 102nd Indianapolis 500. The Juncos team last won the Lights title in 2015 with driver Spencer Pigot.
“It’s a huge relief heading into the finale knowing I just have to take the green flag to officially secure the Indy Lights Championship,” said Kaiser. “My mindset going into the Glen will be to enjoy the race weekend and go for the win with nothing to lose. I’ll have a blast going out there and driving hard for a win in the finale at such a great circuit. Knowing that I’ll have the 3 races in IndyCar for 2018 is a huge motivator heading into next season, I’ll be working extremely hard this offseason to prepare so that I’ll be competitive and show everyone what I’m capable of at the top level.“
Pro Mazda presented by Cooper Tires
The closest-fought series all season has been Pro Mazda, as 21-year-old Brazilian Victor Franzoni has been locked in a titanic battle with Australia’s Anthony Martin, 22, last year’s USF2000 series champion. Franzoni won the most recent race at Gateway Motorsports Park to take a two-point lead into the two races on the calendar at Watkins Glen. Both drivers have five wins this year, and the duo have finished 1-2 in nine of the first 10 races. Both are aiming at the Mazda scholarship of more than $790,000 (out of an overall fund of $1.1 million) toward a season in the Indy Lights class in a Soul Red race car.
“I’m really excited for the final races,” said Franzoni, who drives for Juncos Racing. “This has been the best year of my career and I’m driving better, for sure. I think I grew up a lot this season. For the final, that’s two more races that I have to do my job, do my best and try to win both. It won’t be easy, but I’m ready. Juncos Racing is ready, so it’ll be fun and the most important moment of my life.”
Martin is trying to win a second consecutive Mazda scholarship with Cape Motorsports, as he topped his teammate in a dramatic USF2000 battle in 2016.
“Last year’s title fight has helped me this year,” said Martin. “Just knowing what is needed at the end of the season when it’s crunch time. You really have to work harder than ever with your team to get the most out of your car and yourself. It is super important because every point is crucial and can determine whether you win the championship.”
Cooper Tires USF2000 powered by Mazda
It’s been quite a year for Oliver Askew. The 20-year-old native of Jupiter, Fla. was a karting champion when he won the Team U.S.A. Scholarship to race in England last fall. After an impressive run there, he returned to the U.S. for the Mazda Road To Indy Shootout, where he topped young champions from around the globe to win the $200,000 Mazda scholarship for this year’s USF2000 series. Despite a dearth of open-wheel experience, he earned five straight wins in his Soul Red car with Cape Motorsports early in the year.
“I have been working harder than I ever have to secure this championship,” said Askew. “I think the same can be said about Cape Motorsports and everyone around me that has helped get to this point. We all want this, and if we keep doing what we have been every race so far, there is no reason why it can’t happen. We’ve been the most dominant force this year and I’m confident we can have a successful end. I’ve been in this situation countless times in my career, and what is on the line is very similar to what I went through last year at the MRTI Shootout at Mazda Raceway. The mindset that I’ve developed through this year will be the same in the final race at Watkins Glen, I will be focusing on the elements within my control, and will maximize the opportunity given to me.”
Going into the finale, Askew has seven wins, but he holds only a 13-point lead over Rinus VeeKay, the impressive 16-year-old rookie from the Netherlands. VeeKay, (whose full name is Rinus van Kalmthout) announced at last year’s Indianapolis 500 that he was joining the Mazda Road to Indy, and has turned in a nearly error-free rookie year for Pabst Racing with two wins and 11 podium finishes in 13 races.
“I am very excited to be one of the two USF2000 championship contenders in my rookie season [in a race car],” said VeeKay. “I trained hard for Watkins Glen and I am ready to go.’
Askew and VeeKay will battle for the nearly $400,000 scholarship and a seat next year in the Pro Mazda series in a single USF2000 race Saturday afternoon at 1:30 pm ET.
The Mazda $200,000 Road to Indy Shootout is slated for December of this year to determine the USF2000 scholarship driver for 2018. It brings approximately 20 champions from open-wheel series on five continents to choose a winner.
Watch all of the races with the Road to Indy app, or online at the official site of each series or RoadtoIndy.tv.
Mazda Motorsports boasts the most comprehensive auto racing development ladder system of any auto manufacturer in the world. The Mazda Road to 24 (#MRT24) program offers a number of scholarships to advance drivers up the sports car racing ladder, beginning with the Global MX-5 Cup series and culminating with the Mazda Prototype team. The Mazda Road to Indy (#MRTI) is a similar program that includes Mazda-powered categories of USF2000, Pro Mazda and Indy Lights. In grassroots road racing, more Mazdas race on any given weekend in North America than any other manufacturer. Mazda is also the title sponsor of the renowned Mazda Raceway Laguna Seca in Monterey, Calif.

This is a tale of The Beatles, a house, a mural, an artsy kid, domestic terrorists, classic punk rock, and a lost moment of San Francisco subculture…
For almost two decades, the former “Beatles House,” on the 100 block of Precita Avenue in San Francisco, was covered by a colorful mural of the Fab Four. The mural became a local landmark and tourist attraction; so much so that the Beatles House was used to represent a rehearsal studio in the film “Living on Tokyo Time,” while also garnering mentions on local TV, CNN, and in local newspapers.
Today, the mural is gone… vanished without a trace.
I live down the street from the former Beatles House, however, so neighborhood lore piqued my curiosity about it. Eventually, I found an old black-and-white picture of the house from 1978 and posted it to Flickr:
The posting triggered a lively discussion in the photo comments that attracted both past and present residents of the property, and soon the woman who actually created the mural chimed in to tell her tale.
The Beatles mural was first painted in 1974 by Jane Weems, a young woman who lived in the house during the 1970s and 1980s.
In high school, Jane was the drummer/songwriter for a punk band called The Maggots. The band had a local underground hit with their song “Let’s Get Tammy Wynette.” Stereo Sanctity explains:
Formed around the nucleus of drummer Jane Weems and bassist Robert Mostert in ’78, it seems The Maggots proceeded to get through a veritable bus-load of additional members in their short existence, all arriving and departing from within SF’s high school-age punk milieu, raising merry hell in some parental basement and swiftly developing into the kind of band just as concerned with pasting together fake biographies and press releases for themselves and developing their own brand of icky goofball humour as they were with finding shows to play or recording songs.
You can listen to some vintage Maggots here. (Good stuff!) Jane still looked the part in 1982, and apparently she had a favorite Beatle:
And here’s Jane, hard at work repainting the Beatles House, also in 1982:
So what inspired the Beatles House? In an email to me, Jane wrote:
“I painted the house in 1974, when I was still in junior high school…. I had painted the walls of my bedroom inside the house, first with yellow submarine, then, I did the Elton John “Goodbye Yellow Brick Road” album cover really big on one wall, and other paintings of the Beatles & Elton John on my walls… they were pretty much covered… so, I asked if I could paint a mural on the house, and my parents said yes… so, I started to draw out what I wanted to paint, with a pencil, all freehand, in the low parts that I could reach… after painting that, my mom rented a scaffold, so I could go up higher to get the whole front done… in the middle of this, I had to go to school every day, so progress was slow.
It was fun, both times I painted it… lots of people would stop & watch, or talk to me when I was up there… when I was finished, for years folks would come by, take pix, ring the bell and see what kind of folks lived inside… : ) the SF Bay Guardian gave me a blue ribbon award once for being voted “The best SF remnant of the psychdelic 60’s” even though it was painted in ’74…
Basically, I was just an artistic kid who ran out of room inside, and started on the outside.
And finally, the Where Are They Now? Today, Jane lives in the Midwest, and Beatles House looks like this:

These fluffy protein pancakes are made with six simple ingredients, including protein powder and Greek yogurt.
A quick and tasty breakfast, they take 20 minutes to make, and each serving contains 32 grams of protein!
I created this recipe for my daughter, a talented and dedicated powerlifter. Her challenge? Make protein pancakes without flour (the only dry ingredient being whey protein powder), and make them high in protein, tasty, fluffy, and non-dry.
This is one of those recipes that required several attempts until we were both happy with the result. But once we perfected this recipe, we've been making it regularly. These pancakes are excellent!
Another high-protein breakfast that I like is these chaffles. They contain 36 grams of protein per serving.
You'll only need a few simple ingredients to make these pancakes. The exact measurements are included in the recipe card below. Here's an overview of what you'll need:
- Eggs: I use large eggs in most of my recipes, this one included.
- Vanilla extract: I use a full tablespoon - this is not a typo. Since I use plain unflavored protein powder, this gives them much-needed flavor.
- Sweetener: This is optional, especially if you plan to top the pancakes with sweet toppings. I add stevia to the batter, which is especially important when using unsweetened powder. You can replace the stevia with a granulated or powdered sweetener.
- Plain Greek yogurt: Adds much-needed moisture to the pancakes. I use plain nonfat Greek yogurt because that's what my daughter prefers, but whole-milk Greek yogurt works too.
- Protein powder: I use Biochem 100% Whey Isolate Protein - Natural Flavor. I like that it doesn't have any sweeteners. Many of these powders are sweetened with sucralose.
- Baking powder: Make sure it's not expired. It helps the pancakes rise, although these are not tall pancakes.
The best way to vary this recipe is to use different flavor extracts. I sometimes replace the vanilla extract with coconut, orange, or almond extract. If you opt for these flavors, use just one teaspoon.
Another variation is to use whole-milk Greek yogurt instead of nonfat. I made both versions, and both were excellent, with the whole milk one tasting better. I stick with nonfat yogurt per my daughter's request, but you can use whole-milk yogurt in this recipe.
Protein Pancakes Instructions
Scroll down to the recipe card for detailed instructions. Here are the basic steps for making this recipe:
- Whisk the eggs, vanilla, stevia, and Greek yogurt. (Photo 1).
- Whisk in the protein powder. Whisk patiently and thoroughly until completely smooth and free of lumps, then whisk in the baking powder. (Photos 2,3).
- Heat a nonstick double-burner griddle over medium heat (not higher). Spray it with oil.
- Using a 1.5-tablespoon cookie scoop, pour six to eight mounds of the batter into the griddle (or use a large 14-inch nonstick skillet and cook three or four pancakes at a time). (Photo 4).
- Cook the pancakes over medium heat until they bubble on top, 1 minute or even less. Flip and cook them for just a few more seconds. (Photo 5).
- Remove the pancakes to a plate, add more fat to the skillet if needed, and cook the remaining pancakes.
- Serve immediately. (Photo 6).
- It's important to make small pancakes (I use a 1.5-tablespoon cookie scoop, not a 4-tablespoon ice cream scoop) since the batter is thin and spreads out.
- You should cook these pancakes VERY minimally - they need less than a minute on the first side and just a few seconds on the second side.
Whey protein has a dramatic drying effect on baked goods.
One way to combat that is to use a mix of protein powder and another flour, such as almond flour (not coconut flour which is also drying).
Alternatively, adding plain Greek yogurt to the batter adds moisture and prevents the pancakes from drying out.
No. Pea protein powder or other non-dairy protein powders will not work in this recipe.
If you use flavored protein powder, they should be tasty. However, I use plain unflavored powder, so I add a generous amount of vanilla extract and lightly sweeten the pancakes.
No. They are very good, but they are different than regular pancakes. They are small, thin, and crepe-like. If you're looking for thick, substantial pancakes similar in texture to the regular ones, try these almond flour pancakes.
My daughter and I love eating these pancakes plain, without any toppings, holding them in our hands. You can top them with butter and syrup if you wish.
Sometimes I drizzle them with warmed-up peanut butter, melted extra-dark chocolate, or keto hazelnut spread.
You can keep the leftovers in the fridge, in an airtight container, for 3-4 days. Gently reheat them in the microwave for just a few seconds.
You can also freeze these pancakes in freezer bags, separated with wax paper squares. Defrost them in the microwave.

Fluffy Protein Pancakes
- In a medium bowl, whisk together the eggs, vanilla, stevia, and yogurt.
- Add the protein powder, and whisk thoroughly until completely smooth and blended. Use a rubber spatula to scrape the sides of the bowl if needed.
- Whisk in the baking powder. Then let the batter rest while you heat the griddle. It slightly thickens as it rests.
- Heat a nonstick griddle or a large 14-inch nonstick skillet over medium heat (not higher). Spray with oil.
- Using a 1.5-tablespoon cookie scoop, pour mounds of the batter into the griddle. A double-burner griddle will likely accommodate 8 pancakes, while a skillet will hold 3 or 4.
- Cook the pancakes until they bubble on top, one minute or less. It happens fast! Flip and cook them for just a few more (10-20) seconds on the second side. It's important not to overcook them, or they will turn out dry and rubbery.
- Transfer the cooked pancakes to a plate, cover them with foil to keep them warm, and cook the remaining pancakes. Serve immediately.
- Pea protein powder or other non-dairy protein powders will not work in this recipe.
- I use nonfat Greek yogurt; whole milk yogurt is fine, but it must be Greek yogurt, not regular yogurt.
- In the video above, I made half a recipe. That's why I used just one egg.
- It's important to make small pancakes (I use a 1.5-tablespoon cookie scoop, not a 4-tablespoon ice cream scoop) since the batter is thin and spreads out, and to cook the pancakes VERY minimally. They need less than a minute on the first side and just a few seconds on the second side.

This was a very interesting side dish, easy to prepare, very inexpensive, and something different from the same old pasta. I used 6 oz. angel hair pasta. 3 T of lemon pepper seasoning instead of the lemon juice and black pepper. It needed more olive oil as it soaked up all the oil very quickly and seemed a little dry. My family agreed it was okay, they would eat it again, but not a favorite.

text: I need to give a second price for a job. The first price I gave was for using soil conditioner. This price shall be for bringing in soil. I have to work about 15,000 sq ft. I would be bringing in 150 yards of a very sandy loam. The sandy loam will cost me $35 per yard. Before I can spread the loam I have to spray the whole area with round-up and break it up with the owner's excavator. The sandy loam then needs to be spread to a uniform thickness of about 3 inches. I then will need to till the sandy loam into the soil profile. I must then apply grass seed and starter fertilizer as well as straw. Cost for seed is $110 per 50 lb bag of L perenne Cost for salt hay is $13.00 per bale. Cost for starter fert is $135.00 for the amount needed. Any thoughts as to how much to charge for this job?

“How I Learned to Stop Worrying and Love the Bomb” – US detonated more than 210 nuclear bombs in 17 years
Between 1945 and 1962, the United States detonated more than 210 atomic bombs, releasing massive amounts of radioactive particles into the atmosphere.
A team from the Lawrence Livermore National Laboratory (LLNL) has declassified and preserved several hundred samples from an estimated 10,000 films showing the atmospheric nuclear detonation testing in the Pacific during the so-called Cold War.
Some of the declassified films are posted on the LLNL’s YouTube playlist.

Marshall Islands declare state of emergency as dengue fever outbreak spreads
Health officials in Majuro, Marshall Islands have declared a state of emergency as the outbreak of dengue fever cases doubles in two days.
Disaster Calendar 2011 – October 29
[October 29, 2011] Mass die-offs resulting from human impact and the planetary response to the anthropogenic assault could occur by early 2016. SYMBOLIC COUNTDOWN: 1,600 Days Left to the ‘Worst Day’ in Human History
- Majuro, Marshall Islands. The first case of dengue fever, an infectious tropical disease, was diagnosed at Majuro Hospital last week. The reported cases have now spiraled to at least 63, doubling in the past two days.
- Dengue fever is a virus-caused disease that is spread by mosquitoes.
- The disease’s flu-like symptoms include fatigue, fever, headache, nausea, swollen lymph nodes, vomiting, muscle aches, joint pains and a skin rash that resembles measles.
- The infection can develops into the life-threatening dengue hemorrhagic fever, or result in dengue shock syndrome, leading to dangerously low blood pressure.
- Dengue hemorrhagic fever (DHF) is a severe, potentially deadly infection spread by certain species of mosquitoes (Aedes aegypti and Aedes albopictus).
- Symptoms of DHF are similar to to those of dengue fever, but after several days the symptoms are followed by a shock -like state.
- Shock could cause death.
- DHF has killed hundreds of people in Pakistan, India, China and other SE Asian countries this year so far.
- Increases in temperature, precipitation, and humidity are exponentially boosting vector abundance and disease incidences throughout the world.
- Lahore, Pakistan. At least 31,036 cases of dengue fever have been recorded in Lahore alone, a report said.
- Pakistan’s Health Department has “confirmed four deaths, including two from Lahore, due to Dengue Hemorrhagic Fever (DHF) during the last 24 hours, which brought total figure of deaths to 290 in Punjab and 253 in Lahore.”
- “The dengue fever claimed four more lives on Friday, which brought the death count to 317 in the provincial metropolis.” Said the report.
- USA. Mosquito-Borne Dengue Fever Threat Spreading in the Americas: Dengue Fever Vulnerability in the United States
Dengue vulnerability in the United States. Among the social and environmental factors that increase community vulnerability to dengue and other infectious diseases are poor municipal infrastructure and frequent storm damage to homes. Red areas of the map show U.S. counties that have reported the presence of one or both of the mosquito species (Aedes aegypti and Aedes albopictus) that can potentially transmit dengue fever; blue regions highlight the area encompassing most of the positive counties. Numbers of suspected cases of dengue infection reported from 1995–2005, inclusive, are shown below each state name. Reported counts of suspected dengue fever cases are also included for the six Mexican states that border the United States. Source: NRDC
- Global Impact. Dengue fever and its complications cause about 100 million infections, resulting in 500,000 hospitalizations and 22,000 deaths annually in over 100 countries.
- Dengue incidences have multiplied by 30-fold in less than 5 decades globally.
- The worst hit areas are India, Pakistan, South America, Central America, the Caribbean, Southeast Asia and Africa.
- Currently, about 2.5 people are at risk of for dengue because of climate change.
- “Epidemic outbreaks during 2007 in Brazil, Mexico, Honduras, Paraguay, Costa Rica, Bolivia, and Guyana affected hundreds of thousands,” NRDC report said.
- About 56 percent of Americans (175 million people, as of posting) live in counties where one or both of the mosquito species that can transmit dengue fever have become established.
