After five years of being wracked by emotional turmoil, relatives and dependents of ten persons who perished when two boats collided in the Mazaruni River on January 22, 2013 will finally get closure at the trial of the captains of those boats, scheduled for the current session of the Demerara Criminal Assizes.Keanu AmsterdamBoat captains Devon Thomas and Cabesh Persaud had each been placed on $1 million bail at their arraignment on manslaughter charges in the Georgetown Magistrates Courts in April 2013.When their matter comes up for trial, they are each expected to be indicted on 10 counts of manslaughter.Deon MosesThomas had been captaining the “Matheran”, a vessel which had been carrying 13 passengers, while Persaud had been captaining the “Dube,” which had had six passengers.The allegations detail that on January 22, 2013, while being the captains of two travelling speedboats, they killed a total of ten occupants who had been on board the two vessels in an incident that occurred at Crab Falls in the Mazaruni River.Zaheer BaskhThe persons who perished were Kevon Ambrose, 25, of Vergenoegen, East Bank Essequibo; Keanu Amsterdam, 17, of Barr Street, Kitty, and his 27-year-old brother Ricky Bobb, whose body was recovered afterwards; Jermaine Calistro, 27, of Boodhoo Housing Scheme, EBE; Jewan Seeram of Tuschen, EBE; Deon Moses, 33, of Norton Street, Wortmanville; Ulrick Grimes, 39, of Salem, EBE; Christopher Ramnarine, 21, of Parika, EBE; Zahir Baksh, 34, of Kaneville, East Bank Demerara; and 48-year old Brazilian national Francisco Olivera Alves.Justices Sandil Kissoon, James Bovell-Drakes and Jo-Ann Barlow are on rotation for the current sitting of the Assizes.Justice Kissoon is the lone judge currently presiding over cases that include murder and attempted murder, while Justice Bovell-Drakes is scheduled to preside later in the session. Madame Justice Barlow is hearing cases at the Sexual Offences Court.
Manchester United have enquired about Aston Villa striker Christian Benteke.Louis van Gaal is looking to improve his striking options next season, following the departure of loanee Radamel Falcao, who has moved to Chelsea, while Robin van Persie’s future at Old Trafford is far from certain.Liverpool and Tottenham were thought to be leading the race for the Belgian, but United have been monitoring the situation.talkSPORT understands the Red Devils have been put off by the forward’s £32.5million release clause, but that does not mean it would be impossible to do a deal.The former Genk hitman is not United’s No.1 target, and they are reluctant to meet the Midlanders’ valuation, but would consider an offer should they drop the asking price.Alternatively, Van Gaal could be tempted to trade in one or two of his fringe players in a cash plus player deal. 1 Christian Benteke in action for Aston Villa
Quincy Amarikwa scored a sensational goal for San Jose Earthquakes in their MLS clash with Portland Timbers over the weekend.Picking up the ball in his own half, the American midfielder left three defenders in his wake as he powered forward before unleashing an inch-perfect chip from 40 yards.It proved to be the match-winner, too, as the Earthquakes went on to seal a 2-1 victory over the defending MLS Cup champions.
3 3 Sterling’s woes in front of goal have led to calls for him to be dropped for the Panama clash, but Southgate must keep faith in England’s second-best player, behind Harry Kane. He did miss a couple of chances – as expected – but Sterling’s greatest strength is in his position and ability to get into those goalscoring positions. As long as he continues terrorising defenders in the final third, Sterling plays a vital role for England.Marcus Rashford has emerged as a potential replacement for Sterling, but there is no reason for him to come into the starting XI as of yet.The final question mark for Southgate resides over Ashley Young, who played the full match against Tunisia at left wing-back. He was solid defensively and did get forward, but attacks constantly slowed down when they went through Young due to his need to cut-back onto his right foot.Danny Rose should come in to provide natural width and an ability to cross the ball with his left foot, mirroring Kieran Trippier on the right flank, who was perhaps England’s best player against Tunisia. If England can deliver crosses from both flanks, rather than just the right, they will become a much more fearsome side when on the offensive. Captain Kane saved England with a brace on his World Cup debut There are still no guarantees Dele Alli will be fit for the Panama clash England got their World Cup campaign off to the the perfect start by defeating Tunisia courtesy of Harry Kane’s late, late winner.Kane followed up his first-half opening goal to score the winning header in second-half injury time, moving the Three Lions to second in Group G, behind Belgium on goal difference. talkSPORT will be with listeners all day and all night at this year’s 2018 FIFA World Cup™ with over 800 hours of World Cup content and all 64 games live across the talkSPORT network. 3 Gareth Southgate‘s side return to action on Sunday, and they could book their place in the knockout stage of the competition with a win over Panama.The Panamanians were defeated in their opener, 3-0 by Belgium, and are likely to do against England what they did against the Red Devils – keep it tight and hope to keep a clean sheet for as long as possible.Southgate has some big questions about his big players ahead of the match, with Dele Alli a doubt due to injury, and public calls for Raheem Sterling to be dropped for Marcus Rashford, who was a lively presence when introduced from the bench against Tunisia.So, how will England line-up for Sunday’s match, which you can listen to LIVE on talkSPORT? Look below to see talkSPORT.com’s predicted Three Lions’ XI…The expectation is that the majority of the team will remain unchanged, with Southgate only looking to tweak what proved to be a successful line-up.The absence of Alli through injury is likely to see Ruben Loftus-Cheek come in, following his lively cameo against Tunisia. He can provide the same sort of role as Alli, linking play between midfield and attack, while also providing an aerial threat due to his sheer size.
Finn Harps made the worst possible start to the second half of the season after losing 3-0 to Waterford Utd tonight.McHugh should have scored for HarpsThis is Harps fourth defeat on the bounce and a solid run of results is needed to save the Donegal team’s season.After a terrific early first third of the season, Peter Hutton’s side have found themselves falling apart. Harps can count themselves at least unlucky to get on the scoreboard tonight.Sean McCarron, Kevin McHugh and Jonny Bonnar all should have scored before Waterford broke the deadlock in the 31st minute.But goals from Vinnie Sullivan and Paul Quilty before half-time had Harps on the backfoot for the rest of the game.Kevin McHugh’s shot came off the Waterford post in the 62nd minute. But luck wasn’t on Harps side as Waterford went straight up the pitch with Quilty finding the net again.McHugh went close again with a header in the 71st minute but Waterford closed up shop.Hutton has boasted that he has a large squad to call on if needed.That need may well be justified right now.

Photo Clive WassonDONEGAL County Councillor John Ryan is to seek to run alongside Joe McHugh for Fine Gael in next February’s general election.And that is not surprising given that John Ryan helped FG to attain their highest ever vote in the 2011 general election with 31.6%.The FG convention will see Deputy Joe McHugh selected by popular choice and it remains to be seen what the national executive of the party decides thereafter, reports John McAteer in the Tirconaill Tribune today. The current situation for FG in the new Donegal constituency is quite interesting, With the nine electoral districts south of Laghey now transferred in the new Sligo-Leitrim-West Cavan constituency the current profile of the various parties is quite interesting.When those nine districts are excluded from the 2011 vote across both Donegal constituencies, FG remains with a quota of 1.5 seats (25%): some way behind Sinn Fein on 1.75 quotas (29%) but well ahead of Fianna Fail who are on a quota of 1.2 seats (20%).Interestingly Labour hold almost half a quota: but given the very strong showing of Cllr. Frank McBrearty in Donegal SW and Senator Jimmy Harte in Letterkenny, that profile is hardly surprising.The new constituency profile shows that the combined votes of all others including Deputy Thomas Pringle stands at 17% which is more than a quota.

If early stage companies are supposed to change the world, then Crowdflower and Samasource are model organizations. This morning the two are launching the Give Work iPhone application, a tool that empowers users to increase training and jobs for Kenyan refugees. Rather than playing games or winning badges from location-based services, iPhone users can spend their free time helping others. The joint iPhone application asks users to verify remote work deliverables in order to speed payment to those in need. ReadWriteWeb covered Samasource in early September at the Facebook Fund Rev event. The nonprofit organization demoed a Facebook App that allows application developers to outsource their quality testing to at-risk individuals in countries like Kenya, Cameroon and Ghana. Meanwhile, CrowdFlower is best known as a cloud-based work platform where companies offer Mechanical Turk-style jobs to online laborers. The company launched at this year’s TechCrunch 50 event and describes itself as a “labor as a service” provider. The shared iPhone project is CrowdFlower’s first service involving at-risk communities. The project will allow iPhone app users to work with Samasource’s refugee work program in Dadaab, Kenya. After Kenyan workers complete a simple task such as checking pictures for copyrights, an iPhone user then double checks the worker’s accuracy. By using the application during your daily train or bus commute, you can help improve the lives of numerous workers by endorsing the quality of their work, elevating their career status and speeding the delivery of daily wages. Says Samasource’s Leila Chirayath Janah, “Working with CrowdFlower and iPhone users, the refugees we train in Kenya develop portable work skills and receive higher wages. By training women, youth and refugees to complete paying remote tasks, we give them the ability to build livelihoods and become part of the digital economy.”To check out the application, download it from the App Store.

Many people seem to think HVAC design means you get a load calculation (Manual J in the ACCA protocols) so you know what size system to put in. Hey, that’s a great start. It’s way better than just using a rule of thumb or Manual E (for eyeball).But there’s so much more to real HVAC design than simply finding out how much heating and cooling a building needs when it’s at design conditions. And we might as well start with the fact that my first statement is incorrect: The load calculation does not tell you what size system you need.Load versus capacityIn an article I wrote last year, I went into detail about the difference between getting the load calculation results and sizing your heating and cooling system. You have to factor in the type of equipment you’re using, the efficiency of the equipment, the breakdown of the cooling loads into sensible and latent, and the difference between your design conditions and the conditions at which the equipment was rated. (Sensible load is related to changing the temperature; latent load is the part involved with removing moisture.) RELATED ARTICLESManual J Load Calculations vs. Rules of ThumbManual J Doesn’t Tell You Equipment CapacityThe Difficulties of Third-Party HVAC Design HVAC Design Requirements in the International Building CodesSaving Energy With Manual J and Manual DWho Can Perform My Load Calculations?How to Perform a Heat-Loss Calculation — Part 1How to Perform a Heat-Loss Calculation — Part 2Calculating Cooling LoadsWhen Do I Need to Perform a Load Calculation?We Are the 99% — AND the 1% But it really boils down to a difference between load and capacity. Heating and cooling loads are the amount of heating and cooling in BTU per hour (or Watts) that a building needs. Capacity is how much heating or cooling a piece of equipment can provide. Just remember that loads have to do with the building and capacity has to do with heating and cooling equipment.Of course, there are three types of loads, but for design purposes, we use the design loads, which are based on design conditions. (The other two types are part load and extreme load.)So, the load calculation is the first step. It leads to sizing but doesn’t give it to you right away. (So be careful reading those Manual J reports!) The second step is equipment selection (Manual S in the ACCA protocols), where you take into account those factors I mentioned above. It’s an important step and more involved than just reading the load off the Manual J report.But even that isn’t the most important part of full HVAC design.The dominance of distributionCalculating the heating and cooling loads is the easy part. Even selecting equipment is straightforward. Once you know the loads and have made decisions about the type of equipment, getting the right capacities isn’t hard. But unless you’re using ductless minisplit heat pumps (a great choice, by the way), the next step is in many ways the most difficult. That is, designing the distribution system to make sure the house gets the right amount of heating and cooling delivered to the rooms. (We focus on air distribution at Energy Vanguard, so if you’re doing hydronic heating and cooling, you should talk to someone like Robert Bean at Healthy Heating.)Designing a good distribution means looking at a lot of variables:Placement of supply and return ventsLocation of air handlerFraming obstructionsTypes of fittingsType of design: trunk-and-branch or radialLocation of ducts (conditioned or unconditioned space)Proper air flow, both total through the system and the amount to each roomThere’s a lot that goes into it!When you do it properly, you get a true system. Many homes just get a bunch of components that appear to be a system but really aren’t. Sadly, the bar is really low for heating and cooling systems. Since so few systems get true design, not many people know what they’re missing. If the house stays relatively warm in winter and cool in summer, it gets over the low bar.But here’s what a good HVAC system provides:ComfortQuiet operationDurabilityEfficiencyAs I write this, I’m sitting in our office in Decatur, Georgia. We have our own system for the office, which is great. We don’t have to fight over the thermostat with other businesses in the building, as we did in our previous office. But the system is oversized. It’s loud. And it short cycles. We get blasted with hot or cold air for a few minutes. Then it goes off until the office starts getting a bit uncomfortable in the other direction, when it kicks on again.The good news for us is that we’ve gotten permission from the building owners to replace the system we have with a Mitsubishi system consisting of a ducted minisplit for the two back rooms and wall-mounted ductless units for the front. We’re also getting an Ultra-Aire ventilating dehumidifier for the office. Stay tuned for an article about the installation once we get it all done.The real reasonSo, back to the original question of the real reason for HVAC design, you can see now that it’s a lot more than just proper sizing. That’s important, but more important is making sure the HVAC is a true system, not just a bunch of components pretending to be a system.

Auto-zero basics Sensor manufacturers typically calibrate the devices in the factory to achieve highly accurate outputs, but all sensors experience some offset error once they are in the field. Fortunately, these recurring errors can be mitigated by the end user.Because the auto-zero calibration is implemented in software, it can be performed after the sensor is deployed to the field — and this is highly recommended. When “in-situ” correction is not feasible, auto-zero calibration should be performed after factory calibration — but before deployment. This eliminates errors caused by the stress of mounting the device on the circuit board as well as any errors caused by factory calibration.There are two common scenarios for in-field calibration: At fixed time intervals and when the system detects a temperature change. The two options are not mutually exclusive. Periodic calibrations are particularly important in ultra-low-pressure applications. The reason: Sensors that operate at or below 1 psi are inherently more likely to experience an offset error due to pressure and environmental stress. Temperature-triggered calibrations are recommended because temperature changes are the single major contributor to errors.Before giving an overview of implementing auto-zero calibration techniques, it is worth enumerating several of the most important sources of offset error in pressure sensors. Normal-part-to-part variation and aging have already been mentioned.Stress errors are caused when soldering the devices, or by the use of adhesives to attach the sensor to packaging, or when integrating the sensor into the pneumatic system. Environmental conditions such as temperature variations, humidity, and pressure also contribute to offset error. Even small changes in power supply voltage and unavoidable variations related to device fabrication and factory calibration can skew the output values.For system designers, the good news is that their combined effect does not substantially change the transfer function’s linearity. It is still virtually a straight line. This accounts for the effectiveness of the auto-zero calibration technique.It should be noted that while auto-zero calibration is a valuable strategy for gauge and differential pressure measurements, it is difficult to implement for sensors that measure absolute pressure (a vacuum source is required) and is, therefore, not recommended.Auto-zero calibration is essentially an algorithmic process executed by firmware in an embedded ASIC. A detailed explanation is beyond the scope of this article. A full description, including sample code, can be found in the Tech Note Auto-Zero Calibration Technique for Pressure Sensors. An overview of the procedure follows:Auto-zero calibration methodology starts with measuring and recording a reference pressure under known environmental conditions. It is a good practice to use a reference pressure as close to zero as possible. The process also requires knowing the minimum and maximum operating pressures and their corresponding digital outputs. Because the ideal and real-world transfer functions are both linear, the offset error at the reference pressure provides the offset error at any pressure within the operating limits.Equation 1 describes the ideal transfer function of a pressure sensor:Where: Output = The output reading at any given pressure Outputmin = Ideal output reading at minimum operating pressure Outputmax = Ideal output reading at maximum operating pressure Pmin = Minimum operating pressure Pmax = Maximum operating pressureSince the goal is to capture a pressure reading, Equation 1 can be rewritten as Equation 2 below:It is good practice to take multiple readings and average them as opposed to depending on a single reading.The auto-zero value is obtained by subtracting the average of the measured pressure values from the known reference pressure. Now that the auto-zero value is known, it can be used to adjust for errors as follows:Take a sensor reading.Calculate the pressure using the Equation 2.Subtract the auto-zero value from the measured value to arrive at the corrected value. As pressure monitoring systems become more sophisticated, auto-zero calibration is becoming a critical technology for a growing number of applications. Common medical applications that demand high accuracy include non-invasive blood pressure monitors and miniature pumps. Another new medical application is wound therapy, in which controlled negative pressure over the wound promotes healing. Auto-zero calibration can also maintain a consumer product’s accuracy for its lifetime across a range of consumer and commercial appliances, including coffee makers, dishwashers, and washing machines.Regardless of the application, auto-zero calibration begins by sampling an output at a known reference point. Software running on a signal-conditioning ASIC embedded in the sensor can then adjust the output to the correct pressure. The key concept in this process is the ideal transfer function.An ideal transfer function algorithmically describes the relationship between operating pressure and the sensor’s digital output over the sensor’s operating range. Fig. 1 shows the ideal transfer function of a digital sensor. It also shows the ideal offset, which is the correct output at the pressure that is used as a reference in auto-zero calculations.Fig. 1: Pressure sensors typically display a linear transfer function.

These conditions include normal part-to-part variation and product aging. Fig. 2 shows an example of error offset.Fig. 2: Offset error is the difference between the ideal and real-world transfer functions. Conclusion Auto-zero calibration solves the problem of pressure sensors losing accuracy after they leave the manufacturer. It is an algorithmic solution that is easy and relatively inexpensive to implement because it employs a simple ASIC and a few lines of code. The technology is particularly valuable for a growing number of pressure sensor applications that call for greater accuracy and measurement stability than in the past.>> This article was originally published on our sister site, Electronic Products: “Auto-zero calibration maintains pressure sensor accuracy.” Share this:TwitterFacebookLinkedInMoreRedditTumblrPinterestWhatsAppSkypePocketTelegram Tags: Design Methods
