e ball depends on the number of images captured - the frame-rate - between the ball pitching and hitting the pad.What is the mos Antworten

Despite winning the 2011 World Cup and the 2013 Champions Trophy with DRS in place, India had resisted using the system in bilateral series. On Wednesday the ICC general manager Geoff Allardice and a representative from Hawk-Eye, the ball-tracking technology provider, met top BCCI officials along with India coach Anil Kumble in Delhi.Allardice focused on the independent assessment of the technologies used in the DRS, which was carried out by engineers from the field-intelligence unit at the Massachusetts Institute of Technology [MIT]. The Hawk-Eye presentation explained how ball-tracking technology has been enhanced over the last couple of years.The upshot of the meeting was that two days later India agreed to use the DRS on a trial basis during the Test series against England. Heres an explainer of what their concerns were and how they were allayed.Why did the BCCI not want the DRS? The main reason was a mistrust of the ball-tracking technology used to adjudge lbws. The BCCI said the predicted path after the ball hit the pad was not reliable.How does ball-tracking work? Three elements go into an lbw decision: where the ball pitched, the point of impact on the pad, and the predicted path towards the stumps. The accuracy of the predicted path of the ball depends on the number of images captured - the frame-rate - between the ball pitching and hitting the pad.What is the most significant change in the technology? Cameras with a higher frame rate, and the ability to locate the point of impact on the pad more accurately. How fast are the frame rates now? During the 2011 World Cup, the frame rate of Hawk-Eyes cameras was 50 to 75 frames per second. Hawk-Eyes ultra-motion cameras recorded images at a faster rate in 2013, and their current ball-tracking cameras record images at 340 frames per second.How will a higher frame rate help?It provides a lot more data and hence the calculation of the predicted path of the ball is more accurate. The increased frame rate has allowed the accuracy of the prediction to tighten up significantly, an official privy to Wednesdays presentation said. It means between the ball pitching and the ball hitting the pad there is more information available to go into building a prediction. That was something reinforced by the recent testing of the accuracy of a prediction, when compared to the accuracy of a ball that has not been intercepted.Why did the BCCI have an issue with the location of the point of impact? When judging the point where the ball hits the pad, a key factor is to make sure the ball has not changed path. The BCCI had said there was potential for operator error while identifying the point of impact.How was that issue solved? Hawk-Eye created Ultra Edge to remove that problem. Ultra Edge is a sound based, edge-detection system can identify the point of impact more accurately. When there is a sound of ball hitting pad or bat, it can identify the frame in which the ball hits the pad.What if the operator misses the ball? How will they locate point of impact? Hawk-Eye has added another safeguard to its system: data from every delivery is recorded and can be retrieved in case its needed to build a predicted path of the delivery. Jordan Matthews Jersey . LOUIS -- Valtteri Filppula assisted on three of Tampa Bays four goals, and the Lightning beat the St. Patrick Chung Jersey . Ferrer, trying to win his fourth title on Mexican soil, will next play South Africas Kevin Anderson, who eliminated American Sam Querrey,7-6 (2), 6-4. Also Wednesday, Gilles Simon (6) of France beat Donald Young of the United States 6-4, 6-3, Ukraines Alexandr Dolgopolov downed Frenchman Jeremy Chardy 6-3, 6-4 and Croatias Ivo Karlovic defeated Dudi Sela of Israel 7-6 (4), 6-2. . Robredo, ranked No. 16, bounced back from an upset loss to Leonardo Mayer in the second round of the Royal Guard Open in Chile last week to down Carreno Busta in 1 hour, 25 minutes. On a day filled mostly with qualifying matches, fifth-seeded Marcel Granollers of Spain also entered the second with a 7-5, 3-6, 6-2 win over Aljaz Bedene of Slovenia, while Guido Pella of Argentina defeated Guillermo Garcia-Lopez of Spain 7-6 (6), 6-4 to advance. James Develin Jersey . -- PGA TOUR Canada member Steve Saunders took a three-stroke lead Saturday in the Web. Duke Dawson Jersey . LOUIS -- Lance Lynn was one of the more enthusiastic participants as the St. OMAHA, Neb. -- If theres one thing missing from the 2016 U.S. Olympic trials, it is perhaps one final head-to-head battle between Michael Phelps and Ryan Lochte, arguably the two greatest American male swimmers of all time. And based on the preliminaries of the 200-meter individual medley Thursday morning, the hope for that showdown is still alive.Lochte, swimming with a groin he injured during the breaststroke leg of the 400 IM on Sunday, turned in the fastest prelim time of the morning, at 1 minute, 58.05 seconds. He said he tried to alter his breaststroke kick to minimize the discomfort but felt the pain on the first kick of the breaststroke leg.I was like, damn it, he said. But its a good morning swim.After the race, Lochte hobbled through the mixed zone but told reporters he felt fine. When one suggested he was lying, Lochte replied, I know.Phelps, one day after qualifying for his fifth consecutive Olympics, celebrated his 31st birthday by winning the final heat of the event in a time of 1:58.95. Only Lochte, who swam in the previous heat, had a faster time. I probably didnt warm down enough last night. I didnt really sleep last night, Phelps said. But I said I wanted to go 1:58 so thats good.Phelps said he woke up at 5 a.m. Wednesday unable to sleep and starting firing texts to his coach, Bob Bowman. He pretty much said shut up and get ready for this morning, Phelps said. So I went to sleep for a few hours and came over.ddddddddddddWhen asked what he was doing to celebrate his birthday, Phelps laughed. Im not, he said.Both swimmers will compete in the semifinals of the event Thursday night, in separate heats. The finals are scheduled for Friday night.The list of the top 10 performances ever in the 200 IM is filled with only two names: Lochte and Phelps. They each have five spots on the list, with Lochte the world-record holder. The two have not raced against each other in the 200 IM at a major international meet since the 2012 London Games. Phelps won that battle in a time of 1:54.27.Last summer, when Phelps was suspended from world championships for his September 2014 DUI arrest, Lochte won gold with a time of 1:55.88. Phelps responded at U.S. nationals in San Antonio by swimming the event in the fastest time in 2015, 1:54.75, the eighth-fastest time ever.Earlier this week Phelps scratched the 100- and 200-meter freestyle events to focus on the three events in which he had the fastest times in 2015: the 100- and 200-meter butterfly and the 200 IM.Lochte, 32, has already qualified for the U.S. team in the 200-meter freestyle relay. The 200 IM is his last chance to make the team in an individual event, as he scratched the 200-meter backstroke earlier Thursday morning.I did whats best for me, Lochte said.
