St. Patrick’s Day falls on a Friday this year, which means the Monday-to-Friday nine-to-five crew won’t have to cut the party short this weekend (although Sunday will likely see record sales of tomato juice). If you’re interested in what’s going on for the big green holiday around the country, we broke it down for you, as well as surf and snow conditions in the Irish strongholds.
It’s possible that nowhere celebrates St. Patrick’s Day as hard as folks in the Northeast, who just got blasted by a March nor’easter. While this may be a drag for city dwellers, surfers, skiers and snowboarders are giddy as leprechauns.
While the surf will have dropped after the well-overhead conditions brought on by the storm, if it’s snow you’re after, the luck of the Irish is with you this year. Following a decent early season and then a moody winter, this could be the dump of the year, as resorts in upstate New York, Massachusetts, New Hammy, Vermont and Maine got anywhere from a foot to over 2 feet of fresh.
Vermont will celebrate in the best of possible ways on Friday with ShamRock Weekend at Mount Snow. First and foremost is the $17 lift ticket special on Friday. That rolls into a weekend of skiing and snowboarding with live Celtic music on the Cuzzins Deck stage.
Beantown’s Dropkick Murphys will host three raucous nights at House of Blues Boston. The storied hardcore Irish punks continue Wednesday night’s party tonight and then again Friday night, along with Rebuilder and Blood and Whiskey. If they don’t play “Caps and Bottles,” ask for a refund.
Jacksonville, Florida, goes all in for the occasion at Kona Skatepark. This event is a skater/biker weekend, with Nash Customs leading a motorcycle ride from Daytona’s Bike Week up to Jax, where 20 of the best pool skaters in the country will battle it out at the St. Paddy’s Pool Party, which happens to have beer, bands, BBQ and camping this weekend.
If you’re looking for something a little less aggro in that area, check out the Paddy’s Day Paddle, also in Jacksonville Beach. On March 16, the crew at Jax Paddle Sports will paddle Goodby’s Creek to Wicked Barley for the craft brewery’s festivities, which include limited-beer releases, beer garden games and live music.
The Midwest gets its Irish on this weekend with the Shamrock 5K Beer Run, which is held March 18 in Chicago and then March 25 in Rockford, Illinois. The finish times in Rockford should be higher after a week of detox.
As for the hills, Snowbasin is getting ready to throw down. This week was mostly spring conditions in Utah, but the Basin has 135 inches of base right now and this Friday you can actually find your own pot of gold on the hill as part of the Snow Basin St. Patrick’s Day Party.
In addition to the corned beef and cabbage, Guinness stew and live Celtic music, you can search for the three pots of gold on the mountain and possibly win a 2017/18 season pass.
If you’re on the Pacific coast, of course there was the annual San Francisco St. Patrick’s Day Parade and Festival last weekend, but the Irish population of SF also had overhead swell this week (when don’t they?). It will come down some, but winds look to be light on Friday.
Out at Tahoe, Squaw Valley Alpine Meadows will host the Blarney Band in the Village Events Plaza and Irish whiskey tasting at the Plaza Bar. The very authentic Auld Dubliner will have their own revelry all day as well. Plus, Squaw has gotten over 600 inches of snow this season, so a weekend trip is kind of a no-brainer.
For those in Southern California, Flogging Molly will throw it down this year with the Mighty Mighty Bosstones at The Forum in Inglewood on the holy day.
Hide your own keys and go have fun.


Music by: Pyotr Ilyich Tchaikovsky/Choreography by: Melissa French, Michael French, & Adrienne Keville/Originally Choreographed by: Marius Petipa & Lev Ivanov/Performed by: NewArt School of Ballet/Featuring: Kontras Quartet
As I’m getting older, it seems that holiday traditions become just a bit more special, and what could be more traditional than The Nutcracker? In this delightful ballet, a large family gets together for Christmas, and the daughter of the house is given a nutcracker–the odd soldierly type–as a gift. During the night, she awakes–or seems to–and is waltzed through a journey in which her nutcracker turns into a charming prince, mice attack in droves, and a very sweet court performs for her enjoyment. Altogether, a very credible dream for a little girl to have during the holidays following an overly exciting day.
This past weekend, I had the opportunity to see The Nutcracker performed by our local ballet–the first time I’ve gotten to see it live. I really enjoyed it! The music and snippets of the ballet itself have always permeated the Christmas season, but it wasn’t until I saw the story in its whole that I realized how very seasonally appropriate it actually is. The story is simple, festive, and cute–I enjoyed how much of the story is devoted to what appears to be the girl’s dream. I think the manner in which it was performed when I saw it brought across that atmosphere quite effectively. The choreography was both lovely and fun–lots of big group scenes and intricately interwoven dances, which were neat. And of course, Tchaikovsky’s compositions are always grand and gorgeous, expressive, imaginative, and beautiful. I thought it was interesting that the NewArt School chose to combine recorded tracks with the live performance of the Kontras Quartet; it was surprisingly effective, and the live music was a very nice touch. I would definitely recommend going to see The Nutcracker performed live if you get a chance; it really does add a special touch to the holidays.

Cryptocurrency trading, from the outside, appears very lucrative and worth a try. Seeing people announce their huge wins on social media is definitely enticing, and you may have made the decision to venture into crypto trading. However, the truth is that cryptocurrencies are volatile, and this huge volatility means that traders are exposed to the possibility of significant losses just as they have the chance of making enormous profits. Many times, professional traders carefully strategize their trading actions so that they are insulated from huge losses, thereby maximizing their profits. Hence, as a beginner, it is important to add new strategies to your crypto trades.
What To Know Before Applying New Strategies To Your Crypto Trading Endeavor
- Understand Fundamental Analysis: Fundamental analysis is an approach that involves the evaluation of an asset based on available data; this enables you to predict the prices of crypto based on general news, project-specific news, and other on-chain metrics. Hence, you can estimate the intrinsic value of crypto assets and trade them based on this knowledge.
- Understand Technical Analysis: Technical Analysis co-exists with Fundamental analysis; because it depends on much more historical information than future insights, it lags behind Fundamental Analysis. Nevertheless, traders need to understand Technical analysis because financial markets move in trends, and history often repeats itself.
Understanding these types of analyses is an important prerequisite to crypto trading.
Best Crypto Trading Strategies For Beginners
1. Range Trading: Range trading depends on technical analysis knowledge, specifically support and resistance. It is a strategy that identifies the price range of an asset for a particular period and trades it within the range. Hence, when the price reaches support, the trader looks to buy, and when the price reaches resistance, the trader looks to sell. The idea behind this strategy is that the price will remain in the range for a long while before breaking the support or resistance.
As long as the trader understands the basic laws of support and resistance, it is relatively safe and profitable. However, the trader must be wary of support becoming resistance, resistance becoming support, breakouts, and fakeouts, as these could impact trader psychology within these ranges.
2. Scalping: Scalping is another low-risk strategy that beginners can use to profit from the cryptocurrency market. Scalpers typically complete trades within minutes or even seconds. They never hold positions for more than one hour. Rather than focusing on a few profitable trades, they chase a high volume of small profits. For example, a scalper may target $10 profits 50 times a day instead of looking for a single trade profit of $200 or $500.
Scalpers do not enjoy volatility; they trade with low volatility so as to ride on smaller trends and enjoy small profits before moving to the next trade. During high volatility, scalpers hardly trade because an instant reversal could rip up their trading capital.
3. Reversal Trading: Reversal trading is a bit riskier than the first two methods but is still good enough for Beginners to attempt. Reversal trading notices a trend and attempts to catch it when it reverses. For example, if the market is in an upward trend, reversal traders will be on the lookout for signs that the market has lost buying momentum and is ripe for a reversal; hence, they will begin to enter “sell” trades and try to get ahead of the market. Similarly, if the market is in a downward trend, reversal traders look for reversal signals to enter a “buy” trade.
One common reversal trading tool is the Relative Strength Index (RSI) Indicator. The RSI indicator has an algorithm that computes the average gains and losses in the market for a 14-day period and uses it to judge the strength of the asset being traded.
The RSI chart moves from 0 – 100; when the RSI line is below 30, the asset is considered “oversold,” and with exhausted selling pressure, the trend is expected to reverse upwards. Conversely, when the RSI line is above 70, the asset is considered “overbought,” signaling a downward trend reversal.
Another trend reversal indicators include the “Stochastic Oscillator,” which also has a similar 0 – 100 chart, with the oversold and overbought points at 30 and 70, respectively.
It is important to note that many traders wait for assets to enter extreme overbought and oversold regions like 10 and 90; however, it remains important not to rely excessively on indicators when trading reversals, as they could provide false signals during lengthy trends. It is advisable to engage in some fundamental analysis, checking on-chain information, asset-specific news, and other related information to confirm the bias of a trend reversal.
It is important to note that regardless of any strategy you employ, market volatility could cause sudden upsets. Hence, whether you are a beginner trader or a veteran, practicing excellent risk management while engaging with cryptocurrencies is important. Do not enter trading positions above your emotional thresholds, as it may cause you to make irrational trading decisions, which could lead to heavy losses.

I’m not going to pull a Walt here and make you say thank you for having pointed out for the last several episodes that we were headed to this dark conclusion. A gun in the hand, or within the reach of Walt’s hand, was clearly headed in one direction. But did it really come down to such a seemingly small case of wounded pride? And what do you make of what seemed to be fear, panic, and regret in Walt and Mike’s final moments?

Starting at the beginning, I love how Breaking Bad is never willing to gloss over the details of the aftermath. I think a lot of shows would have said, “And then, they got rid of the evidence.” Instead we got to see a beautifully haunting and detailed deconstruction of the motor bike. The scene was full of details like slicing the hand grips off of the handle bars and sawing the wheels in half to fit them in the barrel. And the haunting sound design of only non-diegetic music floating around was really wonderful. Did you think that Walt actually showed some real remorse during the cold open? I thought there were moments when his face looked like he actually was bothered by what had happened. Then in the next scene we get to hear how he has already rationalized himself into believing that Todd probably did the right thing. Walt has really toned his rationalization reflex muscles.

“It’s always darkest before the dawn.” Hank says this to Walt in an attempt to console him about his marriage with Skyler. But, if you read it as a foreshadowing about what is coming, this episode takes a quick turn towards the darkness. It gets damn dark. Todd has shown initiative to help out the operation. He sought to impress Walt by telling him about the nanny-cam in the house they are about to cook in. And in an attempt to impress Walt and Jesse with quick thinking about keeping the heist a secret, Todd decides to shoot the little boy who sees the end of the heist. I wonder how Walt and Mike are going to react to this terrible situation. Read the rest of this entry »
So, Skylar’s slow burn finally paid off this week. And in wonderful fashion. Round 1 didn’t really have a winner; it mostly just had both sides laying all the cards on the table (analogy 1: cards/poker). Skylar openly admits that her best plan is to suffer through Walt’s mania, trying to keep the kids as far from him as possible, and waiting for Walt’s cancer to resurface and kill or debilitate him. Her strategy is to take as many blows for as many rounds as possible and then strike when her opponent is too weak to retaliate like Muhammad Ali (analogy 2: boxing). This is a terrible thought to Walt because cancer must seem like something that could actually slow him down. But, he sure does seem confident that no other person could threaten his reign as Lord White of Downton Crystal. He believes that he is always a move ahead of his competitor, calling all of Skylar’s potential, future moves (analogy 3: chess). Read the rest of this entry »

If you look up hospitality in the dictionary, you should see a picture of the Embassy Suites Hotel in McAllen. I’m sure you would agree! No wonder the majority of the employees working at this particular hotel have been there 15 to 25 years. When you combine excellent management with a comfortable and friendly environment you get quality employees.
Director of Sales Andrea Rodriguez, who represents the hotel and restaurant in such a professional and positive manner, knew I was reviewing local restaurants and asked if I had been to “Remington’s “lately.” I had been to their Mexican and seafood lunch buffet (best in the Valley) to meet up with friends but, I had not ordered from their dinner menu in a while. Andrea then continued by speaking so highly about the chef and all the delicious food they were serving — I had to set up an appointment.
I decided “Linner” (lunch and dinner) would be a good idea that day. The minute I stepped close to the maitre d’s podium I was promptly greeted by Fernando Rocha, the food and beverage director. He was expecting my arrival and directed me to booth No. 43. I had a terrific view from every angle and was able to admire the beauty of this hotel. Imagine the water fountain in the courtyard, the tropical greenery, warm golden colors surrounding the restaurant and romantic Spanish crooner’s music in the background (brought back memories of San Miguel de Allende).
Fernando mentioned Chef Alvaro Marquez had several courses chosen for my visit. I was impressed and delighted. My attentive waiter began bringing the chef’s creations. First to arrive was the Chicken Tortellini soup ($6) and fresh sourdough bread. This creamy and buttery tasting soup came with sautéed spinach and was topped with parmesan cheese. As soon as I looked up again, I had what looked like a white canvas (square plate) with a piece of art which was actually the “Chicken Scampi Brochettes” ($14). Mama Mia! The six brochettes were also topped with sautéed mushrooms, tomatoes, green onions, fresh garlic, basil, lemon juice, white wine, and melted Monterrey Jack cheese (drizzled with balsamic vinegar).
Next came two magnificent entrees: the Remington’s Filet ($34) and the Roman-Style Salmon ($24). Presenting a gourmet dish involves more than simply placing all the ingredients on a plate. Presentation is everything! How you arrange the ingredients can make the difference between a good meal and an extraordinary experience. There is no doubt in my mind Chef Marquez is a brilliant artist in the kitchen. The eight — ounce tenderloin steak which was cooked to perfection was topped with a divine port Dijon sauce and a medley of summer vegetables. To add more color and dimension to this platter there was a tall martini glass that was filled with creamy Yukon mash potatoes (delicious!) garnished with bits of bacon, yellow cheese and chives — there was also a toothpick on the side with green and black olives and a cherry tomato ( wow - factor! ). The party did not end there!
The grilled salmon (hearty portion) already had a flavorful Roma caper wine sauce but, was kicked up a notch by the crunchy bits of prosciutto, diced green olives, red bell peppers — it was served with a side of wild rice (almonds and red pepper). Both of these entrees were garnished with beautiful flowers carved out of radishes and other tiny vegetables (so — Japanese).
Then came the grand finale! They put in front of me two desserts that had magnificent designs made out of chocolate and fruit — they were true masterpieces (garnished with fresh strawberries that were sliced to resemble roses). The Pina Colada Cake ($8) was served with grilled pineapple slices ,shredded coconut, and sliced almonds — let’s just call it tropical paradise. I also tried the Chocolate Opera Cake ($8) which had a raspberry glaze drizzled on top. This dessert takes chocolate (aphrodisiac) to a whole new level. It’s a rich and elegant dessert is ideal for a chocoholic and perfect with a glass of red wine.
Remington’s Steak House is what fine dining should be: romance, elegance and engaging flavors seamlessly orchestrated into a simple, highly expressive culinary experience. $$
In total bliss,

CROSS REFERENCE TO RELATED APPLICATIONS
This application claims priority to India Patent Application No. 1432/DEL/2008, filed Jun. 16, 2008, which is incorporated herein by reference.
A flue vents emissions to the atmosphere. One type of flue, known as a gas flare, or flare stack, includes an elevated vertical stack or chimney for burning off unwanted gas or flammable gas and liquids released by a pressure relief valve during over-pressuring of plant equipment. A flue is often found on an oil well, an oil rig, in a refinery, a chemical plant, a landfill, or other such facility.
Some emissions from a flare stack are harmful as well as colorless. Examples of colorless emissions include hydrogen and hydrogen sulphide.
Regulatory guidelines, such as those of the Kyoto Protocol or the United States of America Environmental Protection Agency (EPA), impose requirements for monitoring and controlling emissions in terms of the quantity and composition. Monitoring currently relies on technology that is not suitable for use with colorless emissions.
BRIEF DESCRIPTION OF THE DRAWINGS
In the drawings, which are not necessarily drawn to scale, like numerals may describe similar components in different views. Like numerals having different letter suffixes may represent different instances of similar components. The drawings illustrate generally, by way of example, but not by way of limitation, various embodiments discussed in the present document.
The technical problem addressed herein can be described as monitoring colorless flue emissions. The technical solution to this problem includes using a passive infrared sensor and a processor configured to sample emissions and analyze specific heat capacity using a template.
Unlike some monitoring technologies that treat emissions in the aggregate and are unable to discern colorless emissions, a system according to an example embodiment enables monitoring of individual components of colorless emissions. The improved granularity allows for more efficient control of the emission generating facility and effective notification of excursions from normal performance.
An example embodiment includes an infrared (IR) sensor for monitoring colorless emissions from a refinery. The data from the sensor corresponds to a temperature difference between the background and the actual emission in the captured IR image. A difference in specific heat capacity between different components in the emission appears as different shades of gray in the captured IR image. The distribution of the gray levels are analyzed statistically and one or more templates of distributions (corresponding to normal behavior, for example) are generated.
The one or more templates are used for comparison during monitoring to analyze abnormalities in the emissions and for generating a remedial corrective measure via process control. The abnormal behavior can be caused by an increase in a certain component in the emission and when the increase is detected, the present system generates a corrective feedback control signal. The control signal affects the process, for example, to improve combustion of these components before they are sent to the flare stack.
One example includes a system having at least one infrared sensor and a processor. The sensor is configured to provide sensor data based on a gaseous emission from a flue. The processor is in communication with the sensor and is configured to execute a set of instructions to generate an output signal using analysis of specific heat capacity of the gaseous emission.
Typical gaseous emissions from processing feed stocks include hydrogen sulfide (H2S), sulphur dioxide (SO2), and carbon dioxide (CO2), some of which are commonly referred to as acid gases. One example system is directed to monitoring and controlling emissions of acid gas in an industrial process and to reduce sulphur that would otherwise vent to the atmosphere. In addition to adjusting emissions, one example system is directed to issuing a notification or triggering an alarm based on analysis of gaseous specific heat capacity from a passive sensor.
Sensor 110, in one example, includes a passive infrared sensor to monitor a plume of emissions from stack 80. Processor 120, in communication with sensor 110 generates an output based on a comparison of real time emission with data embodied in a template. The template, along with the real time data from sensor 110, includes a gray scale representation of the constituent elements of the plume. Analysis of the real time emissions data, using the template, provides a measure of emissions and can reveal an excursion from normal operation. A control signal generated by the processor is then provided to the emissions generator which can adjust an operating parameter to manage the output from stack 80.
Operational parameters that affect the quantity and the composition of the plume constituents from emissions generator 90 can be managed by a signal on communication link 145.
System 100 includes sensor 110, processor 120, memory 130, and controller 140. Sensor 110 is coupled to processor 120 by communication link 115 and processor 120 is coupled to controller 140 by communication link 125. In addition, controller 140 is coupled to emissions generator 90 by communication link 145. Any of communication links 115, 125, and 145 can include a wired or a wireless connection. A wired connection can include an RS-232 connector, Ethernet connection, or other wired connection. Examples of wireless connections include Bluetooth or other communication protocol such as that which is compatible with a networking protocol specified in IEEE 802. The communication range of communication links 115, 125, and 145 can be configured to allow remote monitoring of a plume from stack 80. System 100, as denoted by the dashed line, represents but one example of a configuration, and the various components can be distributed or combined. In one example, the various elements are connected by a communication network.
Sensor 110 includes a passive infrared detector. A passive sensor operates on the basis of background energy and does not require a synchronized source of light or energy. Sensor 110 can include a video camera or a still camera.
Sensor 110 can be configured for sensitivity to thermal spectral content and, in one example, is sensitive to emissions having a temperature in the range of 300 to 400° C. although other temperatures (especially if a flame is present) are also contemplated. In one example, sensor 110 is sensitive to energy having a wavelength in the range of 8 to 12 μm, however, other ranges are also contemplated.
Sensor 110 is positioned and aimed to monitor the emissions from stack 80, as shown at dashed line 105. Sensor 110 can be located near stack 80 or it can be located remotely. In one example, the distance between sensor 110 and stack 80 is typically 500 m to 1 km.
Processor 120 and memory 130 are in communication with sensor 110 by communication link 115. Content stored in memory 130 can include a set of instructions for execution by processor 120. In one example, memory 130 provides storage for a template or other information. For example, memory 130 can include a look up table, operational parameters, historical data and other information.
Processor 120 can include a server, a workstation, a digital signal processor (DSP), an analog signal processor, a personal computer, or other processor tailored to implement the methods described herein.
Memory 130 can include a read only memory (ROM), a random access memory (RAM), a FLASH memory, or other type of storage device.
Processor 120 executes an algorithm to analyze the data provided by sensor 110 in order to determine presence and volume of a constituent gas element. In one example, processor 120 generates an output signal for managing the operation of facility 85. For example, processor 120 can provide a signal, on communication link 125, to cause controller 140 to adjust a temperature in reactor 92. In one example, controller 140 includes a digital-to-analog converter, a buffer, a driver, or other circuit to generate an output signal. In one example, processor 120 generates an output signal to signal an alarm or other notification, as denoted at notification 99. Notification 99, in various examples, can include an audible or visible alarm, a marker or other signal correlated to a detected event and stored in a memory.
In one example, processor 120 executes an algorithm to generate a bit-map of data corresponding to emissions from stack 80. A gray scale based on the bit-map corresponds to type and amount of constituent elements. Processor 120 analyzes a temperature difference between the background image and the actual emission from stack 80 embodied in the image captured by sensor 110. The differences in specific heat capacity between different gaseous components in the emission are represented as different shades of gray in the image captured by sensor 110. The distributions of these gray levels is analyzed statistically to determine composition and quantity of the constituent elements in the emission plume. Memory 130 stores one or more templates of gray scale distributions, corresponding to normal (or abnormal) performance. The templates enable monitoring of stack 80 to analyze abnormalities in emissions and to manage remedial corrective measures via process control.
This data consists of temperature difference of the various regions in the image represented in terms of two dimensional bit-maps. These bit-maps are statistically analyzed for specific distribution corresponding to components of various gases. A template corresponding to normal operations is established from these statistical distributions. Real time emissions are analyzed by projecting an image (taken during actual operation) onto the template. A deviation from the template indicates abnormal behavior.
Processor 120 and memory 130 are illustrated as discrete components, however, either or both can be distributed or embodied on a single device. In one example, processor 120 and memory 130 are in communication via a digital network.
Controller 140 is configured to receive data from processor 120. Controller 140, in various examples, includes a digital-to-analog converter, a buffer, a driver, or other circuit to generate a control signal or a notification signal on communication link 145.
In various examples, a parameter for a process implemented by emissions generator 90 is adjusted or managed in response to a control signal received using communication link 145. For example, controller 140 may call for a change in a fuel feed rate for emissions generator 90. The plume emitted from stack 80 changes in response to a change in the fuel feed rate.
A variety of process controls can be managed by controller 140. For example, the fuel supplied to a burner or boiler can be adjusted, the operation of a scrubber unit can be controlled, or a setting of a pressure relief valve can be adjusted. In addition, a particular process variable, such as a fuel flow rate, combustion air, a sulphur recovery process, a damper position, an operating temperature, or other process control elements can be modulated by controller 140.
System 100 can be configured as a portable device or as a stationary unit for continuous emission monitoring. For example, as a portable device, processor 120 is powered by a battery. As a stationary unit, system 100 is powered by a metered line service.
In one example, the template is generated using the same stack that is later monitored, however, in another example, a template corresponding to emissions from one stack is used to monitor emissions of a second, and different, stack.
The template represents historical data and enables detection of a deviation from normal operation.
At 220, real time data from sensor 110 is received. The real time data represents time-wise emissions from stack 80. In one example, the real time data includes gray scale bit-maps of infrared images.
At 230, the sensor data and template are evaluated. This can include executing an algorithm using a processor, such as that represented by processor 120. The algorithm includes statistical analysis of the distribution of the gray scales to determine the quantity and composition of the emission.
At 240, an output is generated. The output can be provided to a notification function or can be used to control a process implemented by facility 85. In one example, this can include managing the operation of a stack scrubber or ventilator.
At 310, time duration data for emissions from a stack are received. The data can be received by a processor such as that represented by processor 120. The data can represent normal emissions (or abnormal) emissions. The data includes time-wise representations of emissions from a particular stack 80 that will later be monitored.
At 320, the statistical distribution of the emission data is analyzed and at 330, a template is generated from the analysis. The template can be represented as a gray scale encoded bit-map.
The gray scale reveals variations in molecular content of the plume using data from the infrared sensor. The various regions in the plume exhibit different thermal capacity. For example, the data from the sensor may show that the plume includes 40% H2S, 30% SO2, and 30% CO2. The spectral data from the sensor is mapped to a gray scale to discern the constituent elements of the plume. In one example, a measure of the number of pixels in an image (frequency) having a particular gray scale level is presented as a histogram. In one example, the processor executes an algorithm to perform correspondence analysis in order to determine plume constituent elements. A boundary in a bi-plot can be established using the results of the correspondence analysis and excursions of emissions beyond the boundary can trigger correction or notification. As compared with a histogram, correspondence analysis enables tighter thresholds for which the plant process can be controlled. In one example an excursion of greater than one or two standard deviations will trigger an alarm signal, a control signal, or a notification signal.
Offline portion 530 includes, at 505, receiving sensor data corresponding to a reference emission. The sensor data is collected over an extended period of time and is indicative of normal or abnormal operation. At 510, the data is analyzed in terms of temperature differences (between the background and the image of the flare from the stack). In particular, the data corresponds to specific heat capacity and is encoded in a gray scale, represented as a bit-map. Analysis also includes statistical analysis to establish long term average composition of the plume.
Online portion 540 includes, at 515, receiving sensor data corresponding to a particular emission. The sensor data is collected while stack 80 is emitting a plume. The sensor data provides real time information as to the process and the content and quantity of emission in the plume. At 520, the sensor data is analyzed in terms of temperature differences (between the background and the image of the flare from the stack). In particular, the data corresponds to specific heat capacity and is encoded in a gray scale, represented as a bit-map.
Analysis also includes statistical analysis to establish the composition and quantity of emissions in the plume. Analysis includes comparing real time data from the sensor with the template generated in the offline portion. In one example, this includes projecting a real time image onto the template.
At 525, the output of the analysis includes a control signal which is configured to manage the process supplying the stack. The control signal can be configured to manage the operation of a stack scrubber, a fuel product supplied to the process, a pressure relief valve setting, or any other operating parameter that affects the emissions from stack 80.
One example of a system can be configured for monitoring and controlling gases from various types of flues. One example system can be used to monitor gaseous emissions from the exhaust of an internal combustion engine such as that found on a motor vehicle. An automotive flue gas analyzer can provide analysis of exhaust emissions from a vehicle tailpipe.
One example embodiment includes a method. The method includes generating a template corresponding to a bit-map representation of specific heat capacity for an emission from a flue. Infrared sensor data corresponding to a real time emission from the flue is received. The method also includes evaluating the real time emission by comparing the sensor data with the template and generating a control signal based on the evaluating. The infrared sensor data can include data as to specific heat capacity. The data, in one example, is represented as a gray scale. Evaluating the real time emissions can be evaluated by analyzing a temperature difference. One example includes executing a correspondence analysis algorithm.
The above detailed description includes references to the accompanying drawings, which form a part of the detailed description. The drawings show, by way of illustration, specific embodiments in which the invention can be practiced. These embodiments are also referred to herein as “examples.” Such examples can include elements in addition to those shown and described.

Generalist tree species growing across broad climatic gradients pose an intriguing question about how they can deal with such strong variations in climate. Studying the conductive system of trees may give a clue about their strategies to face rainfall variations.
In southern Chile, García-Cervigón et al. examine hydraulic adjustments at the branch anatomical level in Nothofagus antarctica (Nothofagaceae) and Embothrium coccineum (Proteaceae) across a precipitation gradient from 500 to 2500 mm. Both species maintained hydraulic efficiency but combined with different levels of safety against embolism, which suggests the existence of alternative internal adjustments in coexisting species of temperate forests to face unpredictable climate changes.

BLOOMSBURG, Pa. - Police have made an arrest in connection with a brutal fight near Bloomsburg University.
Kutztown University officials confirmed that Bloomsburg Police came up to campus on Thursday and arrested Angel Cruz, 20, a running back for the Kutztown football team.
Bloomsburg Police tell us a fight broke out early Sunday morning on Iron Street near Bloomsburg University at an off-campus apartment.
The fight involved numerous people and it ended with Jackie Lithgow, 19, of Carlisle and Donald Hoover, 19, of Birdsboro being transported to the hospital. Witnesses say Lithgow was trying to break up the fight.
"He was just standing there and someone came up behind him and hit him in the head. And it is disgusting," said Bloomsburg University student Broc Rutherford.
Police arrested Angel Cruz and took him back to Columbia County for processing.
He is a former football player for Conrad Weiser High School.
Kutztown University issued a statement saying this behavior will not be tolerated and in no way represents the student body. Cruz will be suspended from the football team pending the outcome in the case.
Cruz is facing aggravated assault, simple assault and disorderly conduct charges. Bloomsburg Police say the investigation is ongoing and there may be more suspects.
As for the victims, Hoover has been released from the hospital. But Lithgow is in critical condition.

An Indigenous political activist was briefly detained Saturday following a Trans Mountain pipeline protest in British Columbia's North Thompson Provincial Park on Saturday.
Kanahus Manuel, a spokesperson for the activist group Tiny House Warriors, was arrested by the RCMP after allegedly defying an eviction order from the BC Parks service that was delivered on Thursday.
The group's members belong to the Secwepemc First Nation, which released a statement Saturday afternoon calling Manuel's arrest a "declaration of war."
In the release authored by the Secwepemc Women's Warrior Society, Manuel is referred to as a political prisoner of "the white supremacist RCMP and Park Ranger goons of the Canadian state," whom they said are intent on forcing the Tiny House Warriors from lands the Secwepemc consider ancestral territories. The statement adds the territories were never surrendered to a Canadian government.
Dawn Roberts with the B.C. RCMP said members went to North Thompson Provincial Park to meet with the protesters and discuss the eviction notice. She said the liaison team continued to have conversations with protesters after the arrest, and the remaining protesters began to pack up the tiny houses they'd built.
"Those discussions were extremely positive, very respectful, very understanding," said Roberts in a phone interview.
Snutetkwe Manuel said her sister has been charged with mischief after the group refused to leave the park, although Roberts did not confirm that formal charges have been filed.
An RCMP statement said Manuel was released from custody late Saturday afternoon on a series of conditions and a promise to appear in court at a later date. Additional members of the protest were told they could leave the park on their own or be arrested themselves.
Manuel said the RCMP and BC Parks service have no jurisdiction in the park.
"This is a Secwepemc village site. Our people died of small pox here," she said.
Manuel said there were around six other protesters with her sister when she was arrested, including two village Elders. She subsequently recorded and posted a video to her Facebook page of a conversation with two RCMP officers who stopped her from entering the campsite, which she said was to help her mother pack up.
The protest had originally begun as a three-day tattooing ceremony running from July 6 to 9 and grew into a Trans Mountain blockade by July 11.
Roberts said that she did not know precisely why the eviction order was filed by BC Parks, but did say the tattooing ceremony forced the closure of the park and cancelled reservations for campers.
Kanahus Manuel responded earlier this week, saying her people have been inconvenienced by colonialism for over 150 years.
"We were moved off of our lands. There are internationally protected rights which (say) Indigenous people can use and exclusively occupy their lands to maintain our culture, our language and our ways," said Manuel in an interview.
In a post on the Tiny House Warriors Facebook group Wednesday, Manuel said the Trudeau government left the group with "no choice" but to reclaim their hereditary lands through occupation of the territory that the Trans Mountain pipeline would pass through.
