2019 Audi RS5 Sportback review: Goody two-shoes “Research has shown people readily understand the heating and cooling dynamics to denote directions and the subtlety of temperature change can be perfect for certain feedback that doesn’t require a more intrusive audio or vibration-based cue,” said Alexandros Mouzakitis, JLR’s senior manager for electrical research, in a statement.In the future, this system might have a hand in self-driving vehicles, too. The automaker said that it’s also adapted this temperature-shifting technology to work with gear shift paddles, which could inform a driver that the swap between human and computer control is complete.

Now, Jaguar Land Rover is taking it one step further by bringing temperature into the equation.Jaguar Land Rover this week unveiled its “sensory steering wheel concept.” Developed with the help of Glasgow University, the automaker is investigating whether using heating and cooling can alert drivers to less pertinent information. This wouldn’t replace haptic feedback, but rather it would create a lower-priority tier of messages with its own unique notification method.Here’s how it works. Each side of the steering wheel can be heated or cooled by up to 10.8 degrees Fahrenheit, and the rate of change is adjustable to suit the driver’s preference. It could alert drivers of an upcoming turn in either direction, when to change lanes or if there’s poor visibility ahead. For things requiring much more pertinent notifications, like a lane departure, haptic feedback is still faster and more efficient for communication.

“He Didn’t Play Politics At All.”They still lack power, got water back Sunday and said they have seen no federal officials since Maria struck.“What more do they want us to do?” asked Ray Negron, 38, resting in the shade of a church after a morning collecting debris. “Nobody’s come.”On approach to the airport, Air Force One descended over a landscape marked by mangled palm trees, metal debris strewn near homes and patches of stripped trees, yet with less devastation evident than farther from San Juan.At least in his first moments on the island, Trump remained focused primarily on drawing praise. “He didn’t play politics at all,” he said of the governor, making clear that he considers those who have criticized him to be politically driven. Trump misstated Maria as a Category 5 hurricane; it was Category 4 when it hit Puerto Rico.“I appreciate your support and I know you appreciate ours,” he said. “Our country has really gone all out. It’s not only dangerous, it’s expensive. But I consider it a great honor.” “Let’s Stop Talking About The Death Count.”In Washington, Rep. Luis Gutierrez, D-Ill., noted that many people in more remote areas still in dire straits and in need of food and water. He told CNN, “Let’s stop talking about the death count until this is over.” It stands at 16 now, and 95 percent of electricity customers remain without power, including some hospitals.The most prominent critic in Puerto Rico, San Juan Mayor Carmen Yulin Cruz, attended Trump’s first event, in an airport hangar, shaking Trump’s hand as he went around a table greeting officials before sitting in in the shadow of a hulking, gray military plane.“How are you?” he asked. Her response could not be heard. He thanked her. Days earlier, Cruz said the Trump administration was “killing us with the inefficiency,” pleading for more effective federal leadership in the crisis.Air Force One brought the president, first lady Melania Trump and aides to Puerto Rico in late morning. They were expected to spend more than five hours on the ground, meeting first responders, local officials and some of the 3.4 million people whose lives have been upended by a hurricane that, in the president’s words, left the island U.S. territory “flattened.” Share “Tremendous Progress.”Before leaving Washington, he said Puerto Ricans who have called the federal response insufficient “have to give us more help.”Large-scale protests against Trump, talked about in advance, failed to materialize by early afternoon, with only a few knots of people gathering around San Juan to decry his criticism of local politicians.As he headed out from the White House to visit the island, Trump told reporters that “it’s now acknowledged what a great job we’ve done.”The trip is Trump’s fourth areas battered by storms during an unusually violent hurricane season that has also seen parts of Texas, Florida, Louisiana and the U.S. Virgin Islands inundated by floodwaters and hit by high winds.Nearly two weeks after the Puerto Rico storm, much of the countryside is still struggling to access such basic necessities as food, fresh water and cash.Trump’s visit follows a weekend in which he aggressively pushed back against critics, including Cruz. Trump responded angrily on Twitter, deriding the “poor leadership ability by the Mayor of San Juan, and others in Puerto Rico, who are not able to get their workers to help.”“They want everything to be done for them when it should be a community effort,” he added, scoffing at “politically motivated ingrates” who had criticized the federal work, and insisting that “tremendous progress” was being made.Cruz had begged the administration to “make sure somebody is in charge that is up to the task of saving lives.”Trump and his wife also visited Navy and Marine Corps personnel on the flight deck of the USS Kearsarge. Twitter user @CNNPresident Trump arrives in Puerto Rico 2 weeks after Hurricane Maria ravaged the island.President Donald Trump highlighted Puerto Rico’s relatively low death toll compared with “a real catastrophe like Katrina” as he opened a tour of the island’s devastation Tuesday, focusing on the best of the reviews he and his administration are getting rather than criticism of the federal response to Hurricane Maria.Trump pledged an all-out effort to help the island but added: “Now I hate to tell you, Puerto Rico, but you’ve thrown our budget a little out of whack because we’ve spent a lot of money on Puerto Rico. And that’s fine. We’ve saved a lot of lives.”He said his visit was “not about me” but then praised local officials for offering kind words about the recovery effort and invited one to repeat the “nice things” she’d said earlier. Trump also singled out Gov. Ricardo Rossello for “giving us the highest praise.”“Every death is a horror,” he said, “but if you look at a real catastrophe like Katrina and you look at the tremendous, hundreds of and hundreds and hundreds of people that died, and you look at what happened here … nobody’s ever seen anything like this.” An Upbeat ReportAt least parts of the itinerary were drawn to ensure a friendly reception: Trump was visiting the houses of pre-selected families waiting on their lawns.The president also handed out flashlights at a church, where 200 people cheered his arrival and crowded around him getting pictures on their cellphones.“There’s a lot of love in this room, a lot of love,” Trump said. “Great people.”Asked by AP what he has to say to people still without power, food and water, he spoke of the generators brought to the island and said the electrical grid is being fixed.“Again the job that’s been done here is really nothing short of a miracle,” he said.In the Playita neighborhood in the heart of San Juan, a few miles from the air base where Trump gave his upbeat report on progress, people cleaned sewer water from their homes and businesses, stacked fouled clothes in shopping carts and piled them on street corners alongside wet mattresses and pieces of broken metal roofs. Next StepsEven before the storm hit on Sept. 20, Puerto Rico was in dire condition thanks to a decade-long economic recession that had left its infrastructure, including the island’s power lines, in a sorry state. Maria was the most powerful hurricane to hit the island in nearly a century and unleashed floods and mudslides that knocked out the island’s entire electrical grid and telecommunications, along with many roads.Trump and other administration officials have worked in recent days to reassure Americans that recovery efforts are going well and combat a perception that the president failed to fully grasp the magnitude of the storm’s destruction in its immediate aftermath.According to the Federal Emergency Management Agency, there are now more than 10,000 federal officials on the ground on the island, and 45 percent of customers now have access to drinking water. Businesses are also beginning to re-open, with 60 percent of retail gas stations now up and running.The Health and Human Services Department says federal medical teams with their own equipment and supplies have been sent to help provide care at Centro Medico, a major trauma center in San Juan. Additional teams have been sent to five hospitals in other parts of the island.For many, however, Washington’s response isn’t enough. On Monday, the nonprofit relief group Oxfam announced that it would be taking the rare step of intervening in an American disaster, citing its outrage over what it called a “slow and inadequate response.”
Watching the Apollo landings on the moon as a child I could hardly have imagined I was seeing the end of an era – that of manned exploration of space. Shuttle trips to low earth orbit not withstanding; the human race has stopped reaching for the stars – with manned missions, of course. Now, the new explorers are robots. Will they be the ultimate space traveler? Or will man, with all faults and flexibility, take back this role? Read Part 1 Citation: Manned vs. Unmanned Space Exploration (Part 2) (2005, November 25) retrieved 18 August 2019 from https://phys.org/news/2005-11-unmanned-space-exploration_1.html Right: Japan’s failed Nozomi (Planet B) missionCrewed missions are more costly, but also more effective. Human calibrated experiments setup up on the moon by Apollo missions functioned perfectly for 8 years until shut down for fiscal reasons in 1977. Robotic missions, while they may carry similar instruments, are incredibly difficult to place and calibrate. Ruggedness wins over accuracy so instruments are less sensitive and deliver fewer details in the data they collect. Robots must rely on redundancy to deal with any problems while astronauts can creatively solve almost any problem. The Hubble Space telescope was repaired by teams from the Space Shuttle making it one of the most successful missions ever. Geologists make up the most vocal group of proponents for manned missions. While probe data is useful, they contend one mission with a live geologist could answer all their questions in a few weeks, while endless robotic probes may never be able to provide a clear picture of Mars. A geologist can apply all his or her senses to quickly make determinations as to what to study and what to ignore. Robotic probes could easily miss important clues and waste time on unproductive lines of exploration and study. A human still has much acuter vision than even the best video cameras and, more importantly, can process data with to the solar system’s best supercomputer – the human brain – on the spot.It’s understood the shuttle has outlived its usefulness and new programs are needed. Even NASA Chief Administrator Michael Griffin has suggested the development of the Space Shuttle and International Space Station was a mistake by saying, “It is now commonly accepted that was not the right path. We are now trying to change the path while doing as little damage as we can.”Scientists aside, public opinion has done much to keep manned spaceflight alive. Poll shows a resounding 80% or more people support continuation of manned programs like the shuttle on and the International Space Station despite accidents and lack of worth as space labs. Humanity sees itself conquering space directly, not by proxy.Indeed, support for astronauts extends well beyond simple polling. People are spending money to go into space as tourists. Chapters of the Mars Society exist in almost every major country – all pushing for manned missions with goals like the human exploration of Mars.“Although some aspects of exploring and colonizing Mars still need refining and fine tuning, the lion’s share of the technology and the understanding of the human condition are already in existence. The major missing factor is simply the realization and the commitment necessary to begin. The people of the Mars Society are working to educate and convince the political powers, the industry leaders, and you and me. We all have a stake in this.” – Dr. Robert Zubrin, author “On to Mars 2”, founder Mars Society. This document is subject to copyright.

Low-cost Moon mission puts India among lunar pioneers Part 2The Case for Human Spaceflight While no scientist can deny the value of robotic space exploration, many feel the need for complementary manned programs. Most agree that, for basic survey missions, robotic probes produce dramatic results. It’s in field study that scientist crewed missions could do better. Ironically, it is the same people who run the unmanned space missions that are clamoring for human crewed missions to follow them up.Part of the problem is the limited abilities and scope of each robotic mission. To save money and reduce failure rates to a minimum, robotic probes are stripped down to essentials. Although these probes gather important data, much of it is ambiguous for lack of the probe’s ability to do follow up tests. Today’s robots cannot start up new lines of investigation. Raw data is useful but often raises more questions. Even worse, the data is often completely unexpected leaving the scientists at a loss to explain the results. They need further missions to run different tests and, the cornerstone of all good science – verification by repeatedly testing the same area over time.This repeated testing of results becomes difficult with unmanned mission failure rates. Take the Mars exploration programs: out of 31 missions by the USSR, Russia, the US and Japan since 1960, all but 10 failed and only 5 met their original goals. Compare that to the high success rates of astronaut crewed missions – almost 90%. Right: FMars habitat undergoing tests at Devon Island, Nunavut, CanadaPresident Bush has even stepped up with a promise finish the International Space station by 2010 – only five years late – and for a manned mission to the moon by 2020. Much political wrangling will need to be done, however, if the funding is to materialize. Safety problems with the shuttle program continue to dog NASA as well, further putting in doubt these goals.It will take more than just the words of a few politicians to keep manned spaceflight alive. The will of the people needs to be felt through their representatives on Congressional budget committees – we have the money and the technology. Do we have the will?One avenue now being actively explored by space enthusiasts is private funding. Corporate spending in spaceflight has been grater than governments since 1996 when $77 billion dollars was invested. Private industry has more than 1,200 launches – mostlycommunications satellites– before 2007. Like in the days of early pioneering, private initiative is becoming the mainstay of space exploration. The question is: can manned space exploration pay? After all, corporations are about by profit for their shareholders.We must go to space – if not now, later, as the living area and resources on Earth dry up. Will we be on the forefront of this exploration, living in space and adapting it to our will like the hardy pioneers of old? Or will we stay at home to see these new horizons via virtual reality – only moving in to our new space bound homes when they are safe and comfortable?by Chuck Rahls, Copyright 2005 PhysOrg.com Explore further
Despite assurances from law enforcement agencies to ensure safety and security of the churches after the arson at Dilshad Garden church, Christmas celebration in Delhi will be a low key affair this year.The churches will organise prayers and perform other rituals but some argued the recent tragedy has marred the festivity to maximum extent. The sense of fear in the mind of community people can be judged from the fact that they hesitate to discuss the upcoming festival and its preparations.

Lack of security arrangements and mishandling of the incident by concerned authorities have also added to the woes. While the security was strengthened after the incident, hardly any police personnel can be seen around churches these days. The public-police meeting for restoring confidence among the community has also been scheduled after Christmas,” said Saji, one of the care-takers of St Stephens Church in Dilshad Garden. Also Read – Man who cheated 20 women on matrimonial websites arrestedA visit to churches in Dilshad Garden corroborates Saji’s fears. The churches wore a deserted look with no visitors. “Every year, the devotees would throng to churches days before the Christmas. We are going to organise street prayers and have invited people from different communities to participate in that. But we are doubtful about people’s attendance at the prayers”, said Mathew, an attendant at St. Sebastian Church where the massive arson had taken place a couple of weeks ago.On the other hand, police officials claimed to have taken adequate security measures to avert any untoward incident. “We have instructed senior police officials to deploy necessary force outside each church in the city to ensure safety of the community. Surprise checks by officials are also being conducted to check security measures,” a senior police official, requesting anonymity said.
