Heres Sandos criteria for each tier • Tier 1 qu

first_imgHere’s Sando’s criteria for each tier:• Tier 1 quarterbacks can carry their teams week after week and contend for championships without as much help.• Tier 2 QBs are less consistent and need more help, but good enough to figure prominently into a championship equation.• Tier 3 are quarterbacks who are good enough to start but need lots of support, making it tougher to contend at the highest level.• Tier 4 is typically reserved for unproven starters or those who might not be expected to last in the lineup all season. Voters used the fifth tier sparingly.With that criteria in place, Arizona Cardinals quarterback Carson Palmer landed in Tier 3, ranked 15th overall and the top-ranked passer in that 10-player tier.Palmer ranked ahead of Kansas City’s Alex Smith, Miami’s Ryan Tannehill and San Francisco’s Colin Kapernick, among others.A head coach said he thought Palmer was more of a backup at this point based on an inability to move. That was an outlier view, however. Thirteen voters placed Palmer into the second tier. Those placing Palmer lower pointed to injury problems.Sando also pointed out one league personnel director who lauded the Cardinals for recognizing that Palmer had gas left in the tank. The great quarterback debate rages on.ESPN.com’s Mike Sando is the latest to tackle the challenge of ranking the National Football League’s 32 starting quarterbacks. The writer enlisted the help of others, though. In an ESPN Insider piece, Sando used a panel of 35 league insiders who were asked to put each quarterback into one of five tiers. Tier 1 included the league’s best, while Tier 5 was for the bottom-feeders. Derrick Hall satisfied with D-backs’ buying and selling Top Stories “At one point, I’d have told you he is a 3,” another director said. “I am saying he is a high 2. Coming out of Oakland I thought his arm was dying. I give Arizona credit. They saw something I did not. His arm has more life to it than I thought.”Six quarterbacks landed in Tier 1 — Green Bay’s Aaron Rodgers, New England’s Tom Brady, Indianapolis’ Andrew Luck, Pittsburgh’s Ben Roethlisberger, Denver’s Peyton Manning and Drew Brees of New Orleans.

University of London to make EV radiators unnecessary with simplified thermal management

first_imgSource: Electric Vehicles Magazine City, University of London has received a £121,000 grant from both the Engineering and Physical Sciences Research Council (EPSRC) and Williams Advanced Engineering to test several promising thermal management technologies in a project known as Battery Integrated Power Electronics for EV Drive train (BIPED). The project seeks to distribute battery packs and circuitry in a way that simplifies heat management and significantly reduces vehicle weight.Currently, power electronics are packed together, generate large quantities of waste heat and require heavy cooling systems. BIPED suggests an alternative: distribute both battery packs and power electronics into small units for each motor. City researchers claim that this change will simplify thermal management to the extent that radiators will no longer be needed. Also, power cables can be made shorter (and therefore lighter) and will only need to handle 25 A instead of 300 A. Lower voltage and current transistors can be used, further reducing weight. Though there are more units to handle, BIPED proposals do not increase the number of internal communications wires. As a final bonus, each battery module is set to be less than 50 V, making post-crash recovery much safer as well. Source: City, University of Londonlast_img read more
