first_imgBrian Molefe is the current Group Chief Executive of Transnet and his secondment is with immediate effect. His experience in having turned around the Public Investment Corporation and providing stability at Transnet is a clear indication that Molefe is no stranger in leading complex institutions.Brian Molefe, the newly appointed acting chief executive of Eskom.Minister of Public Enterprises Lynne Brown• Download the statement (PDF)On Wednesday I briefed the nation on the current state of the grid and the reasons for the implementation of stage 3 load shedding by Eskom.I am informed that the system is still tight. However, Eskom and its engineers are doing their utmost to contain further interruptions at our power plants.With than announcement I also informed the nation that I am looking at immediate steps to stabilise leadership at Eskom both at Executive and Board level.Eskom is a strategic asset and one of the major utilities on the continent. It is therefore critical that Eskom operates optimally and contributes to economic growth of the country.The decision to institute an inquiry has created uncertainty on Eskom’s ability to ensure security of supply and successful delivery of its build programme. I am happy to announce that the Terms of Reference for the appointment of an investigator is concluded and Dentons has been appointed to lead the enquiry. I will await a report from the Board as this process unfolds.In order to stabilise the executive leadership and after consultations with various stakeholders including President Jacob Zuma, Deputy President Cyril Ramaphosa, the Boards of both Transnet and Eskom, I have decided to second Mr Brian Molefe as Acting Chief Executive of Eskom.Mr Molefe is the current Group Chief Executive of Transnet and his secondment is with immediate effect.His experience in having turned around the Public Investment Corporation and providing stability at Transnet is a clear indication that Mr Molefe is no stranger in leading complex institutions. Given Eskom’s current financial and operational position, I am confident that we will be able to draw on his experience and understanding of the financial markets.This secondment is also considered in light of Mr Molefe’s extensive understanding of the public sector and the environment in which State-Owned Companies operate. As is evident from his CV, he has been involved with entities such as Telkom, the Airports Company of South Africa, the National Empowerment Fund and the Export Credit Insurance Corporation amongst others.Ladies and gentlemen, I now call on Mr Molefe to join us.This secondment allows Mr Sinethemba Khoza to resume his role as a member of the Board. I want to take this opportunity to thank Mr Khoza for acceding to the call to step in at a critical moment when his leadership was needed.To consolidate the leadership at Eskom, I will soon be submitting my recommendations to Cabinet on appointing additional members to strengthen and augment the required skills on the Board.In conclusion, I would like to thank the Transnet Board for agreeing to the secondment of Mr Molefe and the manner they dealt with this request.I would also like to appeal to the Eskom Executives and employees to welcome Mr Molefe and provide him with all the necessary support that he would require as he steers the company.Condensed CV of Mr Brian MolefeMr Molefe’s qualifications include the following: Masters of Business Leadership, University of South Africa; Post-Graduate Diploma in Economics, London University, School of Oriental and African Studies and a Bachelor of Commerce, University of South Africa.Majors: Accounting and Economics.Other training courses include: a Programme for Young Global Leaders, Kennedy School of Government, Harvard University (Cambridge, Mass.

If she prevails on Saturday, it’ll be in her 43rd major tournament — the fourth-most appearances among women at the most elite level before winning a first Grand Slam title.The 27-year-old Dane is also nine years removed from her first major final at the 2009 U.S. Open (a loss to Kim Clijsters). She then had a five-year wait for a second shot in New York, falling to Serena Williams in the 2014 final.And now another 3 ½ long years for another opportunity.“I always believed in myself,” Wozniacki said. “I was just giving myself time. I think if you don’t feel like you can go all the way in tournaments, then to me there’s no sense in playing. So for me it’s always I want to be competitive, I want to be the best, and that’s why I’m still playing.”ADVERTISEMENT NEXT BLOCK ASIA 2.0 introduces GURUS AWARDS to recognize and reward industry influencers They’ve had similar careers to this point: they are steady, consistent performers week-to-week who have climbed all the way to No. 1 based on the quantity — if not necessarily the quality — of their results.At the Grand Slams, both are all too familiar with the role of runner-up — Wozniacki losing twice at the U.S. Open, Halep twice at Roland Garros.FEATURED STORIESSPORTSWATCH: Drones light up sky in final leg of SEA Games torch runSPORTSLillard, Anthony lead Blazers over ThunderSPORTSMalditas save PH from shutoutAnd in a twist of fate, both enter the Australian Open final playing with what Wozniacki calls “house money” — they’ve each saved match points earlier in the tournament and feel they’re making the most of their second chances.In Halep’s case, it’s actually a third chance.

(AP Photo/Vincent Thian)MELBOURNE, Australia — For both Caroline Wozniacki and Simona Halep, the Australian Open women’s final on Saturday is a chance to put the demons of past Grand Slam near-misses behind them.One will finally walk away a champion. The other will have to shake off another loss in a major final and be left to wonder when, or if, another chance will come again.ADVERTISEMENT Globe Business launches leading cloud-enabled and hardware-agnostic conferencing platform in PH The 26-year-old Halep hasn’t had such long stretches between title chances — her losses came in the 2014 and 2017 French Opens to Maria Sharapova and Jelena Ostapenko, respectively — but she’s certainly endured the more heart-breaking defeats.Halep was leading by a set and a break against Jelena Ostapenko at last year’s French Open before faltering down the stretch. And against Sharapova in 2014, Halep came in as the favorite but was broken at 4-all in the third set before losing a draining, three-hour final.But Halep believes she’s turned a corner in the past year and is better able to handle pressure moments on the court. Her comeback from multiple match points down in Melbourne is a testament to a new mindset.“I was in this position in the French Open, so maybe I can make a better match,” she said. “I feel more experienced. Also stronger mentally. And the way I play, it’s different. I feel I’m more aggressive.”The bonus in Saturday night’s final is that winner also takes home the No. 1 ranking. It would be a six-year gap for Wozniacki if she achieves it. But both made clear this isn’t their goal.“It’s also my dream, to win a Grand Slam title,” Halep said. “But, you know, it’s always tough when you are close.”Wozniacki knows all too well how this feels — and she’s hoping the third time proves lucky for her.“Regardless of what happens now, I’ve done my best,” she said. “I believe if you really put everything into it, eventually things are going to go your way.” Torres knocks out Osenio, Kelly scores stunner in ONE prelims Read Next 2 ‘newbie’ drug pushers fall in Lucena sting Brace for potentially devastating typhoon approaching PH – NDRRMClast_img read more

The Warriors And Rockets Have Reinvented Modern NBA Defense Yes Defense

HOUSTON — The NBA Finals are the crown jewel of the playoffs for obvious reasons, but it’d be hard to argue with anyone who views this vaunted Western Conference finals matchup between the Golden State Warriors and Houston Rockets, which opens Monday night, as this year’s main event.The Warriors have two of the best three players in the world in their starting five, have won two of the past three titles and appeared borderline annoyed by having to face questions about whether they’re concerned to be starting a series without home-court advantage for the first time in their recent championship era. The Rockets won an NBA-best 65 regular-season games, have likely MVP James Harden and future Hall of Famer Chris Paul in their backcourt and possess a group of sweet-shooting teammates who stretch the floor as if it’s made of Play-Doh.The offensive firepower — Golden State and Houston finished No. 1 and No. 2 in offensive efficiency and virtually averaged the same number of points per 100 possessions — guarantees we’ll hear plenty about how well these teams score. But because of that, something else about the Rockets and Warriors may fly beneath the radar: The NBA’s two best clubs are even further ahead of the curve on defense. In a league that’s more reliant than ever on the pick-and-roll offense, these defenses are unmatched when it comes to their versatility and ability to switch assignments on the fly.Houston defended a screen-and-roll by switching on 1,406 possession chances during the regular season, while Golden State orchestrated 1,075 switches of its own, according to data from Second Spectrum and NBA Advanced Stats. These teams — which more than doubled the switch totals compiled by 20 other squads — were outliers: The Lakers were the only other club that broke 800 switches during the 2017-18 season.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2018/05/rox.mp4Media error: Format(s) not supported or source(s) not foundmejs.download-file: https://fivethirtyeight.com/wp-content/uploads/2018/05/rox.mp4?_=100:0000:0000:21Use Up/Down Arrow keys to increase or decrease volume.And it isn’t just that the Warriors and Rockets switch a lot. They also use the strategy to fuel their high-octane offenses. Houston forced 3.5 turnovers per 100 switches, while Golden State forced 2.4, the best rates in the league, according to Second Spectrum.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2018/05/warriors.mp400:0000:0001:38Use Up/Down Arrow keys to increase or decrease volume.That ability — having two similarly sized players trade their defensive responsibilities quickly enough during a pick-and-roll that the offense doesn’t gain an edge — speaks to the length and versatility these Western Conference foes have. And it takes on added importance in a matchup like this, in which the Warriors and Rockets use an array of screens (albeit differently1The Warriors use fewer pick-and-roll plays than any other team in basketball, while the Rockets use more direct screens than any team, according to Second Spectrum data. That said, Golden State, seeking to free up Klay Thompson, sets more off-ball screens than any club.) to free up their most lethal shooters beyond the 3-point line.“You have to cover more ground than ever before. It’s amazing: Sometimes I’ll turn on the classic sports channel and find Lakers-Celtics games from the 1980s — some of the best games ever — and the game is played in this tiny little radius. Now it’s way out on the perimeter,” Warriors coach Steve Kerr said. “Every possession was, you dump it into the post, a double comes, and you might see six or eight threes taken in a game. But everything was different. The rules were different. The talent is different. Very few low-post players anymore. The league’s adapted. Coaches have adapted. Things are ever-changing. And you have to change along with that.”Anyone who’s followed the Warriors’ dominance these past few years knows a huge chunk of that success stems from Golden State’s ability to go small and play Draymond Green — who may not even be the ideal height for a traditional small forward — at center. That alignment, with the addition of Andre Iguodala, gives the Warriors four long-limbed clones who are laterally quick enough and strong enough to cover almost anyone. With that defensive speed, Golden State can gamble a bit more on that end; it knows the opposing offense generally won’t be able to find mismatches, even if a switch has taken place.“At the end of the day, it’s really just another way for us to cut off the other team’s options with our versatility,” said Green, the league’s reigning defensive player of the year, who sometimes calls an audible — and moves a teammate out of the way — before a screen occurs to be in position to thwart the play.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2018/05/dray.mp4Media error: Format(s) not supported or source(s) not foundmejs.download-file: https://fivethirtyeight.com/wp-content/uploads/2018/05/dray.mp4?_=300:0000:0000:12Use Up/Down Arrow keys to increase or decrease volume.Houston has also made life difficult for opponents with its versatility on defense. By and large, the Rockets have been far more successful on defense than most would have guessed, jumping to sixth in defensive efficiency this season after ranking 21st in 2015-16 and 18th in 2016-17. Adding the sticky-handed Paul certainly factored into that improvement, but plugging free-agent signings Luc Mbah a Moute and P.J. Tucker into the lineup likely did even more for the defense.“Their ability to guard 1 through 5 makes it so much easier for us. That’s why we’re so much better on defense this year,” Houston guard Eric Gordon said of the duo, which sometimes shares the frontcourt despite neither standing taller than 6-foot-8. (Nonetheless, the lineup pays dividends: Houston, trailing by 14 heading into the fourth quarter at Portland in December, came back to win by 7 while using Mbah a Moute and Tucker at the 4 and 5 for the entire period.)Mbah a Moute, in particular, has become a vital piece. According to a defensive dashboard created by Nylon Calculus contributor Krishna Narsu, the wing’s versatility was highly unusual. This season, he was one of just seven players to spend at least 15 percent of his time guarding each of the following positions: point guard, shooting guard, small forward and power forward.Unsurprisingly, the Rockets struggled in his absence during the middle of the campaign, enduring a season-long five-game losing streak. The Rockets’ 101.2 defensive rating with Mbah a Moute on the court this season would have ranked best in the league on a team scale, while their 105.4 rating without him would have had them just slightly above average, at No. 12.Above all else, Mbah a Moute and Tucker carry so much importance because they make Rockets coach Mike D’Antoni — one of the game’s brightest offensive minds who was never really known for switching with his defenses — more comfortable utilizing this style of play.“To even have a chance against a team like Golden State, you have to make a point of not being put into rotations. They’ll kill you that way. So I’m just happy we have a roster full of guys to where it makes sense to be able to switch the way we do,” he said.To be sure: Neither team is breaking from decades of tradition with this strategy on defense, even if they are using it far more often than everyone else. On some level, this is no different from what the LeBron James-era Miami Heat did when it rode small ball to a championship in 2012. (Kerr would be the first to tell you that he never envisioned Green playing the rim-protector role when he took the Warriors job. “We didn’t know Draymond was Draymond yet,” he told me.) Beyond that, it wouldn’t be fair to gloss over how unbelievably dominant these teams are on offense, given how big a role scoring plays in their success.Yet there are reasons to think that creative, well-timed switches will heavily factor into this series as the chess match of hunting for what each team perceives to be mismatches unfolds.The Warriors have made no secret of the fact that they like to post up Kevin Durant when they spot him being guarded by Paul following a screen.Video Playerhttps://fivethirtyeight.com/wp-content/uploads/2018/05/durant.mp400:0000:0000:45Use Up/Down Arrow keys to increase or decrease volume.Meanwhile, Harden and the Rockets are even less shy about attacking Stephen Curry; they’ll often run multiple pick-and-rolls until they get him on an island for a 1-on-1 matchup. In fact, they used this tactic six times in a seven-possession span during the final four minutes of the teams’ last regular-season meeting Jan. 20, a 116-108 Houston win.“We’re just gonna watch film and find ways to attack them offensively,” Harden said when I asked about that sequence. “We’ll take our shots, play unselfishly. Pretty simple.”Curry thinks this will mean isolating him in the same way this series. “I hope it’s every single play,” he told The Athletic’s Anthony Slater. “If you look at the ‘Hamptons Five’ lineup that’s out there, I would probably do the same exact thing if I was coaching against me. You’ve got Klay (Thompson), Andre, Draymond and KD out there. I embrace those opportunities to get stops and try to make it tough in those iso situations … and just do my job.”The likely MVP seeking out a former MVP for a 1-on-1 matchup, for the right to play in the NBA Finals. A pretty cool outcome, all thanks to how these juggernauts force and handle switches on defense.Check out our latest NBA predictions. read more

Digicel Defends amidst vociferous protest

first_imgFacebook Twitter Google+LinkedInPinterestWhatsAppProvidenciales, TCI, October 18, 2016 – Digicel defended its company reputation in a late day interview with Magnetic Media yesterday aimed at setting the record straight on what is happening at the telecommunications organization; and there to send the strong message to islanders was current CEO, Sinead O Marcaigh and EJ Saunders who remains a Director and shareholder of Digicel.Saunders said he is an investor in Digicel and would never sit on a board which supports disenfranchising Turks and Caicos Islanders.  EJ Saunders’ name appeared on placards of demonstrators who protested outside of the Leeward Highway headquarters of the company on Monday; the move by Digicel to make redundant seven staffers, including six Turks and Caicos Islanders has been met with vociferous objection.To our question about the make-up of their staff, Ms O Marcaigh explained that 60% of its senior management are Turks and Caicos Islanders, that they had increased staff to 75 since their right-sizing during the acquisition of WIV and overall, there are currently 11 work permit holders, and that figure will soon be reduced to nine.Protesters and press releases have called for Digicel to rehire, to instead let work permit holders go and attorney Finbar Grant even recommended to workers to take strike action and shut Digicel down.Former Telecoms boss, Drexwell Seymour though painted an entirely different picture in an op-ed piece he published online; saying essentially the redundancies are commonly done as companies evolve to keep pace with market demands.Magnetic Media learned too, that none of the political leaders seen in the protest have requested a meeting with Digicel to discuss their grievances face to face; at least one of the protestors is asking the country for the opportunity to be its Premier come next General Elections.The Immigration Board, in a rare interview given by its Chair, Sheba Wilson, threatened the revocation of work permits at Digicel and O Marcaigh admitted to Magnetic Media that the company is under review by the Board.It was also explained by both Saunders and O Marcaigh that they are confident the Immigration Board will find that Digicel is being fair and sincere in its need for the work permits to improve on its telecommunications network in these islands.

Apart from any fair dealing for the purpose of private study or research, no part may be reproduced without the written permission. The content is provided for information purposes only. More information: Artificial Skin Ridges Enhance Local Tactile Shape Discrimination, Saba Salehi, John-John Cabibihan, Shuzhi Sam Ge, arXiv:1109.3688v1 [physics.med-ph] DOI:10.3390/s110908626AbstractOne of the fundamental requirements for an artificial hand to successfully grasp and manipulate an object is to be able to distinguish different objects’ shapes and, more specifically, the objects’ surface curvatures. In this study, we investigate the possibility of enhancing the curvature detection of embedded tactile sensors by proposing a ridged fingertip structure, simulating human fingerprints. In addition, a curvature detection approach based on machine learning methods is proposed to provide the embedded sensors with the ability to discriminate the surface curvature of different objects. For this purpose, a set of experiments were carried out to collect tactile signals from a 2 times 2 tactile sensor array, then the signals were processed and used for learning algorithms. To achieve the best possible performance for our machine learning approach, three different learning algorithms of Na”ive Bayes (NB), Artificial Neural Networks (ANN), and Support Vector Machines (SVM) were implemented and compared for various parameters. Finally, the most accurate method was selected to evaluate the proposed skin structure in recognition of three different curvatures. The results showed an accuracy rate of 97.5% in surface curvature discrimination.via ArXiv Blog As with many areas of science, even the seemingly simple stuff turns out to be quite complicated on closer view. The human fingertip for example, covered with skin unlike that of any other body part, has raised ridges that allow people to feel the difference in texture between wood and metal or silk and linen. It can also detect temperature, and as it turns out, is also involved in figuring out the curvature of objects that are touched. Consider for example, the keys on a cell phone, or a television remote control. It’s these kinds of abilities that Saba Salehi, John-John Cabibihan and Shuzhi Sam Ge are trying to emulate in their lab in Singapore. To begin, they’ve started with the easiest of the bunch, trying to figure out if artificial fingerprints fitted on a robot hand can tell how roundish an object is.To find out they built a touch sensor comprised of a base plate, embedded sensors and a raised ridged surface; all on a 4mm square. They then set about testing the simple sensor in a variety ways to see if they were able to sense things with it in different ways, specifically as it was applied to flat, edged and curved objects. They also built an identical sensor except that the raised portion was flat instead of ridged, to serve as a control.They found that the raised sensor did indeed provide more feedback (resonance) information than the one with the flat surface, so much so that they were able to tell the difference in the three types of objects with 95.7% accuracy.Undoubtedly, more research will be done in this area by this group and others, and perhaps very soon, robot fingertips will become just as sensitive, if not more, than our own, leading to a whole new generation of gentler robots, able to perform tasks with both dexterity and a deft touch. © 2011 PhysOrg.com (PhysOrg.com) — Over the past couple of decades, many people in and out of the science community have watched the steady progress being made in robotics. It’s an exceptionally interesting field due to the anthropomorphic nature of the results. Each new step brings such machines closer to emulating us even as we look forward to the next step. One interesting thing about robotics is that certain areas seem to be advancing faster than others. Robot arms for example are old news, new research is focused more on hand movements. And has advances in hand movements have been made, more research has come to focus on finger movements and finally tactile sensations. Now new work by a trio of researches from the National University of Singapore describe in their paper published on the preprint server arXiv, how affixing artificial fingerprints to robot fingers can increase tactile “sensation” allowing such a robot to discern the differences in curvature of objects.last_img read more
