You feel like you are in a bubble.”Since she’s secured her place on the team going to London, her day job has taken a back seat. Hultzer is putting in extra time to perfect her skill before taking on 64 of the world’s best archers in London, and some of these athletes shoot arrows for a living.Although she is looking forward to the Games – this is her first time at the Olympics – she doesn’t want to become too competitive.“I always want to remember the joy of shooting, and not get too wrapped up in scores and results. One has to enjoy the sport,” she says. “Just going to the Olympics is a major achievement.”Her coach and manager, Johan Steyn, a seasoned archer who has been playing the sport since the age of nine, says that waiting for confirmation from the South African Sports Confederation and Olympics Committee was nerve-wracking.“We knew that there was a 90% chance that we would qualify for the Olympics,” Steyn says. “It never crossed my mind that one day I will represent my country at the Olympics. I was in shock the whole day.”Training for the big dayHultzer says that she is training as much as she can before flying out to London, but she also has to be careful not to train too much. “I am trying to shoot as many arrows as I can to keep up my condition,” she says.She explains that training for archery is somewhat different to other sports. “With this type of sport, although you are not running, you want to make sure that you keep your pulse steady,” she says. “Once the adrenalin starts pumping you can’t be calm and your bow starts moving.”This is where Steyn’s expertise in laser technology comes in handy.The coach, who is a senior laser technologist at the Council for Scientific and Industrial Research (CSIR), is building a pointing device – similar to a laser pointer – to help Hultzer with her form and accuracy during training.In archery the correct body posture is critical. “Archery is not a power sport, it has everything to do with skill and aiming,” he says.At a glance archery might look easy, but it is a very difficult sport to master.“You need arm strength, back strength and perfect alignment,” he says. “You would think that arm strength is important but it is actually back strength that is needed. “According to Steyn there is room to use laser technology in many other sporting disciplines, if only more coaches would realise its potential to help athletes improve their game.“My work involves coming up with creative applications for lasers – and this is one of them,” he says.The benefit of training with lasers is that archers can immediately identify weak areas.“What I am developing is a laser that hooks onto the belt to point out if there is any hip movement,” he explains.Steyn first saw how effective lasers can be when he observed renowned archery coach Pascal Colmaire, World Archery Federation coach and development officer, train in Morocco. “He was using the technology so I thought I could develop a similar application,” he says.He says laser technology helps athletes to correct errors in posture or technique while they are training, instead of playing back a video of their performance.“Athletes get feedback in the moment and they can make adjustments immediately,” he explains. “Using a laser is an excellent tool to show what you are doing wrong, or right.”CSIR National Laser Centre manager Dr Ndumiso Cingo says Steyn’s foresight to apply lasers to archery is a great achievement for the council. “We are even prouder that he also utilises laser technology in his coaching techniques – just another thing that lasers can do well,” Cingo says.Promoting archery in South AfricaBesides coaching, both Steyn and Hultzer are involved in developing archery in South Africa.Steyn says that the upcoming Olympics is the ideal platform. “Karen’s participation in the Olympics can be a big inspiration for other archers in South Africa to improve their skills and perhaps also have a go at qualifying for the next Olympics,” he says.Hultzer, who is also a part-time archery coach, says that children can benefit greatly from taking up archery, particularly those who struggle to concentrate in class or have learning disabilities.“One of the amazing things about this sport is that it helps kids who are struggling at school,” she says. “With this sport, kids can learn how to focus, it builds self-esteem and some children have even seen their school marks improve.”When the Olympics is overHultzer may have found her niche in archery. As much as she loves landscaping, the sport is taking up so much of her time – between coaching and training for the Olympics – that she is considering making it a fulltime career.Currently she coaches people of all ages, from six to as old as 78, and she believes that through archery she can make a difference in people’s lives. “I find that with my students they always just want to see what the score is – but it is what you do that is more important,” she says. “Archery is not about instant gratification. It is a journey.”• Slideshow image courtesy of Meriden Archery Clublast_img read more

Insulating Mechanical Pipes

first_imgSTEP 7: INSULATING MECHANICAL PIPESCode: N1103.3 Mechanical-system piping capableof carrying fluids above 105°F (41°C) or below 55°F (13°C) must be insulated to a minimum of R-3.What it means to you: Although this might clear up an inconsistency between previously stated requirements of 1-in. insulation (which is approximately R-4), it at least raises the required insulation values from R-2 to R-3 as a compromise. Remember, though, that this code focuses on mechanical pipes, which could carry fluids such as glycol, not potable-water pipes.The 2009 building codes reflect practices that not only increase energy efficiency—air-sealing measures and increased insulation, for example—but also address sustainable building practices, such as moisture control.Other segments of this series:Part 1: Air SealingPart 2: InsulationPart 3: LightingPart 4: Programmable ThermostatsPart 5: Insulating Mass WallsPart 6: Efficient WindowsPart 7: Insulating Mechanical PipesPart 8: Exceeding the Energy CodePart 9: Vapor Retarders 9 Steps to A Greener CodeNew homes built using the 2009 International Residential Code (IRC) or International Energy Conservation Code (IECC) will be more energy efficient than ever.

Tata makes worker safety wearable available to competitors

first_imgOther industrial companies will be able to purchase Tata Group’s own wearable for factory workers, in a new move to boost the Indian giant’s hardware sales.Last year, Tata launched a wearable for its own workers to reduce accidents. It is able to track heart rate, temperature, movement, fall detection, and ambient gasses in the vicinity.See Also: Is Nokia growing into contender in emerging tech?Even though workers and unions were worried about Tata’s ability to snoop on workers at the start, both eventually caved in and the device is now quite popular in the factories, according to Tata.The wearable has watch functionality—apparently a popular feature for low-paid factory workers—and is built to sustain damage. It doesn’t do much outside of the workplace apart from show the time.A whole new revenue stream?The firm is hoping that with its almost ubiquitous brand identity in India, it will be able to sell the units to smaller factories. Miners and freight companies are two major industries targeted by Tata with the wearable. Although some targeted client industrial players may compete with the Indian conglomerate, the wearables focus could be an untapped revenue stream.“For these programs, we are looking at potential revenue of $1 billion and a profit of $100 million is possible,“ said Tata Group technology chief Gopichand Katragadda to the Economic Times. “Right now, our partner for go-to-market is Tata Communications. We are working on the pricing model. What might work in a B2B model is a monthly subscription rather than a certain price.“Industrial wearables and IIoT devices are starting to become more prevalent, as owners start to look for ways technology can reduce accidents and improve productivity.

What Makes Markelle Fultz An NBA Draft Favorite

If early reports turn out to be accurate, Markelle Fultz is headed to the Philadelphia 76ers. The Sixers traded the third pick in this year’s draft and a protected first round pick in either the 2018 or 2019 draft to the Boston Celtics. It’s a mammoth deal for both teams, and it has ramifications for the long-term outlooks of both. But lost in the commotion of assets changing hands and the deal’s implications on other big-ticket trades are the particulars about the player at the heart of the deal: Fultz himself.Playing in the Pacific Northwest on a nontournament team (and missing a chunk of time because of injury) made Fultz one of the most anonymous presumptive No. 1 picks in living memory. Just about every argument about the Washington Huskies guard is phrased in the subjunctive — a theoretical commodity more than a concrete set of skills. But dig down into what actually makes his game so good and it becomes obvious in a hurry that Fultz is a monster.Fultz has been billed as a pick-and-roll playmaker, which is true but vague. He doesn’t sit up high and find long, surprising passing lanes like James Harden does, nor does he feint and jab on a defense until it cedes ground like Chris Paul does. Fultz’s game is built around his jumper and his handle. He’s a strong shooter off the dribble and a strong enough dribbler to operate in tight spaces and get to the rim, where he’s an excellent finisher. This means defenses have to crowd him wherever he is on the floor, whether it’s 25 feet from the rim or having turned the corner on a pick and roll. And if a defense sends help, he’s a willing passer to the open man, even if that means a 40-foot, cross-court pass.The Huskies scored 109 points per 100 plays1Per Synergy Sports Technology when Fultz passed out the pick-and-roll, including 115 points per 100 on passes to spot-up shooters. To get a sense of how much the team relied on Fultz, consider those numbers in their full context. On spot-up jumpers that weren’t set up by a Fultz pick-and-roll or taken by Fultz himself (101 points per 100 plays), the Huskies managed just 82 points per 100 plays. That’s dreadful. That would have ranked 333rd out of 351 D-I schools. But Fultz was able to draw so much attention and create such good shots for his teammates that they went from one of the worst-shooting teams in the country to one of the best when he set them up.Not just any player commands the sort of defensive attention Fultz saw — even when he is by far the best player on his team. And what makes Fultz special is how good he is shooting off the dribble in traffic. On all pull-up jumpers, he scored 102 points per 100 plays, which is already very good. But when he was working out of the pick and roll, that number shot up to 118 points per 100 plays, as Fultz took advantage of the little bit of daylight created by the screen to get a slightly better look or to a better spot on the floor.Having a god-tier pull-up jumper is an increasingly critical skill for NBA guards, but so is finishing at the rim. Being a genuine threat on the drive is the reason the pick-and-roll offense works — it’s what makes James Harden and Russell Westbrook nightmares for opponents and what powers the LeBron Offense in Cleveland. And Fultz scored 130 points per 100 plays when going to the rim out of pick-and-roll plays. He has a tight (though not exactly dazzling) handle — aided by a nice little hesitation/head-fake move that freezes defenders who have to respect that pullup — and he uses it to get into the lane at will.All that said, the most spectacular offense in the league can’t do much for you if you’re giving up points at the other end. The Huskies were abysmal on the defensive end — they ranked 250th of 351 D-I men’s teams in defensive SRS — and Fultz’s personal numbers aren’t much better. He ranked in the bottom third of all D-I men’s players while defending all but one shot type, according to Synergy. But the defense Fultz plays in the NBA will be much different, mainly because the Huskies spent a lot of time in zone, and that asks players to do very different things to contest shots and deny space than pro-style defenses. But defense should still be a concern. Fultz has good physical tools — he averaged 1.6 steals and 1.2 blocks per game — and he was actually quite good the few times he was isolated in man-on-man situations, but his attention away from the ball will need the same improvements as most rookies.Fultz is a top overall prospect because he’s very, very good at things that are fundamental to the pro game — pick-and-roll playmaking, pull-up shooting, finishing at the rim. He has fewer jaw-dropping highlights as fellow prospects Lonzo Ball or De’Aaron Fox do (though he does have a few); but he has fewer holes in his game, as well. If there’s one thing that could unravel his game as a pro, it would be his shot not translating. It’s not exactly the same species of skepticism as the concern trolling over Ball’s shooting form, but there’s at least some reason to wonder if Fultz will be as lights-out from deep in the NBA. His range doesn’t extend far beyond the college line, and his release is on the slow side. Just as concerning, he shot 64.9 percent on foul shots, which ESPN Insider’s Kevin Pelton pointed out is a slightly better predictor of NBA 3-point shooting ability than college 3-point percentage on its own — and Fultz wasn’t overwhelming enough from 3 (41.3 percent) to make up for the free throws.But the way Fultz had to manufacture his offense should also be taken into account: He practically never had an open shot he didn’t create himself. He scored 116 points per 100 plays coming off of screens, but that was largely because of the same things that make him good in pick and rolls, not effective screens. Fultz’s Washington teammates didn’t set great screens, but this is an area where he needs to improve as well. If Fultz is going to play off the ball in the NBA he’ll have to improve his feel for how to angle his runs to get the screener between the defender and the spot where he wants to catch the ball.This of course leads back to the question of how Fultz will fit in with the Sixers. Given that early reports suggest forward Ben Simmons, last year’s No. 1 overall pick, will play a de facto point guard role for Philadelphia, an ideal fit for Fultz might be as a sort of über-Bradley Beal. John Wall handles the majority of playmaking for Washington, and Beal runs off of flare screens and other off-ball actions to free himself up for jumpers. But when Wall doesn’t have the ball, Beal runs a fair bit of pick and roll himself (despite being a weak dribbler) and generally controls the offense. A similar division of labor between Simmons and Fultz would make a lot of sense for Philly.But that’s deeper into specifics than we need to go for now. Teams tend to find ways to make things work with players who can dribble, pass and shoot. For now, Fultz is a perfect fit for a Philly roster that needs ballhandling and shooting, and just as important, a perfect fit for the directions the NBA game is headed. read more
