Increasing Electric Car Battery Performance More information: Ibrahim Abou Hamad, M. A. Novotny, D. Wipf, and P. A. Rikvold. “A new battery-charging method suggested by molecular dynamics simulations.” Available at arxiv.org. Doi: 10.1039/b920970k.via: Technology Review (PhysOrg.com) — Part of the headache of having to constantly recharge batteries is not just how often they need to be charged, but also the time it takes to charge them. In a new study, researchers have proposed a charging method that could greatly reduce the charging time of lithium-ion batteries, which are used in everything from electronic devices to electric vehicles. The new method uses an additional oscillating electric field (besides the charging field) that should be capable of charging a lithium-ion battery in a fraction of the time compared with traditional methods. Researchers Ibrahim Abou Hamad from Mississippi State University and coauthors have developed the new charging method thanks to revolutionary developments in molecular dynamics simulations. In their study, the researchers simulated the lithium-ion battery-charging process by simulating the intercalation (i.e. “insertion”) of lithium ions into the battery’s graphite anode. Although intercalation is just one part of the charging process (along with diffusion), it dominates the charging time.In the charging process, lithium ions first diffuse within the battery’s electrolyte until they reach the graphite anode. At this interface, ions must overcome an energy barrier in order to be intercalated into the anode. In their simulations, Hamad and his team found that an additional oscillating electric field can lower this energy barrier, enabling lithium ions to intercalate more quickly into the anode. The oscillating field also increases the diffusion rate, which helps further reduce the overall charging time, albeit to a lesser extent.Specifically, when the scientists applied an oscillating square-wave field with a frequency of 25 GHz and an amplitude of 5 kCal/mol to the graphite sheets in the anode, the lithium ions intercalated into the graphite sheets within an average time of about 50 nanoseconds. By changing the amplitude of the oscillating wave, the researchers found that they could further improve charging time by lowering the energy barrier and speeding up intercalation. Their simulations showed that the dependence of the intercalation time on the amplitude is exponential, meaning that a small increase in amplitude leads to a large increase the intercalation speed, which offers the potential for very fast charging times. In the future, the researchers plan to further investigate the new method, including analyzing how changing the frequency of the oscillating field effects the charging time. They noted that the new method might provide an increase in battery power densities, as well. This document is subject to copyright.

LEDs efficiency exceeds 100

first_img(PhysOrg.com) — For the first time, researchers have demonstrated that an LED can emit more optical power than the electrical power it consumes. Although scientifically intriguing, the results won’t immediately result in ultra-efficient commercial LEDs since the demonstration works only for LEDs with very low input power that produce very small amounts of light. More information: Parthiban Santhanam, et al. “Thermoelectrically Pumped Light-Emitting Diodes Operating above Unity Efficiency.” Phys. Rev. Lett. 108, 097403 (2012). DOI: 10.1103/PhysRevLett.108.097403Physics Synopsis © 2011 PhysOrg.com Darpa seeks new power dynamic for continuation of Moore’s Law An LED’s power conversion (wall-plug) efficiency varies inversely with its optical output power. Wall-plug efficiency can exceed 100%, the unity efficiency, at low applied voltages and high temperatures. Image credit: Santhanam, et al. ©2012 American Physical Society Journal information: Physical Review Letterscenter_img The researchers, Parthiban Santhanam and coauthors from MIT, have published their study in a recent issue of Physical Review Letters.As the researchers explain in their study, the key to achieving a power conversion efficiency above 100%, i.e., “unity efficiency,” is to greatly decrease the applied voltage. According to their calculations, as the voltage is halved, the input power is decreased by a factor of 4, while the emitted light power scales linearly with voltage so that it’s also only halved. In other words, an LED’s efficiency increases as its output power decreases. (The inverse of this relationship – that LED efficiency decreases as its output power increases – is one of the biggest hurdles in designing bright, efficient LED lights.)In their experiments, the researchers reduced the LED’s input power to just 30 picowatts and measured an output of 69 picowatts of light – an efficiency of 230%. The physical mechanisms worked the same as with any LED: when excited by the applied voltage, electrons and holes have a certain probability of generating photons. The researchers didn’t try to increase this probability, as some previous research has focused on, but instead took advantage of small amounts of excess heat to emit more power than consumed. This heat arises from vibrations in the device’s atomic lattice, which occur due to entropy.This light-emitting process cools the LED slightly, making it operate similar to a thermoelectric cooler. Although the cooling is insufficient to provide practical cooling at room temperature, it could potentially be used for designing lights that don’t generate heat. When used as a heat pump, the device might be useful for solid-state cooling applications or even power generation.Theoretically, this low-voltage strategy allows for an arbitrarily efficient generation of photons at low voltages. For this reason, the researchers hope that the technique could offer a new way to test the limits of energy-efficiency electromagnetic communication.

Black holes do not exist where space and time do not exist

first_img Explore further In a new paper, physicists Ahmed Farag Ali, Mir Faizal, and Barun Majunder have shown that, according to a new generalization of Einstein’s theory of gravity called “gravity’s rainbow,” it is not possible to define the position of the event horizon with arbitrary precision. If the event horizon can’t be defined, then the black hole itself effectively does not exist.”In gravity’s rainbow, space does not exist below a certain minimum length, and time does not exist below a certain minimum time interval,” Ali, a physicist at the Zewail City of Science and Technology and Benha University, both in Egypt, told Phys.org. “So, all objects existing in space and occurring at a time do not exist below that length and time interval [which are associated with the Planck scale]. As the event horizon is a place in space which exists at a point in time, it also does not exist below that scale.”When Ali talks about “all objects,” he literally means everything around us, including ourselves.”We also do not exist physically below that length and time interval,” he said. “However, for us, our house, our car, etc., it does not matter if we do not exist at any one point of space and time, as long as we exist beyond a certain interval. However, for the event horizon it does matter, and this causes the main difference in our calculations.”Gravity’s rainbow Gravity’s rainbow arises from attempts to develop a theory that combines both the theory of general relativity and quantum mechanics. To fully solve the problems related to black holes, or even the beginning of our universe, physicists require a theory of quantum gravity.”Even though no one has been able to discover such a theory, there are various candidates,” Ali said. “These include ideas like taking space and time as fundamentally discrete, or using some mathematical loops as a fundamental quantity to construct space and time, or even replacing particles by tiny strings, and many other exotic ideas. Journal information: Europhysics Letters (EPL) “What many of these models have in common is that it can be inferred from them that the energy of a particle cannot get as large as possible, but that there is a maximum energy that any particle can reach. This restriction can be easily combined with Einstein’s special theory of relativity, and the resultant theory is called the doubly special theory of relativity, or DSR.”As the physicists explain, it is possible to generalize DSR to include gravity, and this theory is called gravity’s rainbow. “General relativity predicts that the geometry of space and time curves in the presence of matter, and this causes gravity to exist,” Ali said. “Gravity’s rainbow predicts that this curvature also depends on the energy of the observer measuring it. So, in gravity’s rainbow, gravity acts differently on particles with different energies. This difference is very small for objects like the Earth. However, it becomes significant for objects like black holes.” Information paradoxThe point of the work is not simply to abolish one of the defining features of a black hole, but rather the results could resolve the 40-year-old black hole information paradox that began with work by Stephen Hawking back in the 1970s. At that time, Hawking proposed that black holes emit radiation as they rotate, causing them to lose mass faster than they gain mass, so that they steadily evaporate and eventually disappear altogether. The paradox in this scenario is that Hawking radiation originates from the mass of objects that fell into the black hole, but (in theory) the radiation does not carry complete information about these objects as it radiates away from the black hole. Eventually this radiation is expected to cause the black hole to evaporate completely. So the question then arises: where does the information about the objects go? In everyday life, shredding or burning paper documents may be common practice to destroy information, but according to quantum theory, information can never be completely destroyed. In principle, the initial state of a system can always be determined by using information about its final state. But Hawking radiation can’t determine the initial state of anything. Many proposals have been put forth to solve this paradox, including the possibility that some information slowly leaks out over time, that information is stored deep inside the black hole, and that Hawking radiation actually does contain complete information. One of the most developed explanations of the paradox is called black hole complementarity, which is based on the idea that an observer falling into a black hole and an observer watching from a distance see two completely different things. The in-going observer sees information (in the form of himself) pass through the black hole’s event horizon, but to a distant observer it appears that the in-going observer never actually reaches the event horizon due to the strange effect in general relativity of time dilation. Instead, the distant observer sees the information being reflected away from the event horizon in the form of radiation. Since the two observers cannot communicate, there is no paradox (though to many people, such a solution may sound even stranger than the paradox itself). Planck-scale limitsIn their new paper, Ali, Faizal, and Majunder show that something very different happens in black hole complementarity when there is no event horizon below a certain length and time interval, as suggested by gravity’s rainbow. Instead of it appearing to the distant observer that it takes an infinite amount of time for the in-going observer to reach the event horizon, in the new theory, that time is finite. In other words, the distant observer eventually sees the in-going observer fall into the black hole. Using this new insight gained from gravity’s rainbow, Ali, Faizal, and Majumder claim that the mysteries surrounding a black hole arise from the fact that space and time are being described at a scale at which they do not exist. “If we restrict our description to scales at which space and time exist, then the apparent paradoxes associated with black holes seem to naturally resolve,” Ali said. “For example, as the information paradox depends on the existence of the event horizon, and an event horizon like all objects does not exist below a certain length and time interval, then there is no absolute information paradox in gravity’s rainbow. The absence of an effective horizon means that there is nothing absolutely stopping information from going out of the black hole.” Beyond black holes In addition to offering a solution to the black hole information paradox, the physicists explain that the existence of minimum length and time intervals reminds us that it is important to know what questions one is allowed to ask in physics to get the correct answer. The scientists explain this idea using the analogy of a metal rod:”We can ask, how much will a rod bend at a given force without breaking the rod? When we apply a force so great that it breaks the rod, it is meaningless to talk of bending that rod. In the same way, in gravity’s rainbow, it becomes meaningless to talk of space below a certain length scale, and time below a certain interval.”The most important lesson from this paper is that space and time exist only beyond a certain scale,” Ali concluded. “There is no space and time below that scale. Hence, it is meaningless to define particles, matter, or any object, including black holes, that exist in space and time below that scale. Thus, as long as we keep ourselves confined to the scales at which both space and time exist, we get sensible physical answers. However, when we try to ask questions at length and time intervals that are below the scales at which space and time exist, we end up getting paradoxes and problems.” (Phys.org) —The quintessential feature of a black hole is its “point of no return,” or what is more technically called its event horizon. When anything—a star, a particle, or wayward human—crosses this horizon, the black hole’s massive gravity pulls it in with such force that it is impossible to escape. At least, this is what happens in traditional black hole models based on general relativity. In general, the existence of the event horizon is responsible for most of the strange phenomena associated with black holes.

Wont You Be My Soviet Neighbor Mr Rogers Bizarre Appearance on Russian

first_imgIn 1987 Fred Rogers and his team went on a remarkable journey. They were leaving the cosy TV set of Mister Rogers’ Neighborhood and trading net curtains for The Iron Curtain. This unassuming gentleman in his cardigan and tennis shoes, so beloved of U.S. audiences, was in many ways a definitive American. At that point the show had been running for over 20 years, and was set to last more than a decade after.Mister Rogers, a gentle Republican, represented a wholesome slice of life which for some was rather bland.Photograph of Mister Rogers in the late 1960s.In an article looking at new documentary Won’t You Be My Neighbor, The Telegraph writes that “Mister Rogers’ Neighborhood – there’s no getting around it – was as square as square could be… In one episode, they offered to give the children a sense of how long a minute was. They set an egg timer, and just sat there in silence, on air, for a whole minute.”Fred Rogers speaks before a United States Senate Commerce Committee hearing in support of public broadcasting, May 1, 1969.His presence in Red Square suggests a truly strange chapter in the history of American television and, as some of his Soviet hosts suspected but was never confirmed – espionage.Yet Mister Rogers was merely doing what he’d always done.

Their destination was Spokoinoi Nochi, Malyshi, which translates as Good Night Kiddies. Like Mister Rogers’ Neighborhood, the series was a stalwart of national television that had been entertaining children since the Sixties.The New York Times reported on the junior version of East meets West, describing the Russian program as “a mixture of homey morals about manners and kindness, and creative animation involving everything from clay figurines to textured puppets that live out Russian fairy tales, old and new.”Photo of Fred Rogers as a senior in high school.Legendary journalist Ted Koppel had pointed out the similarity, inspiring Newell to mention a crossover to producers. And so Mister Rogers went to meet presenter Tatyana Vedeneyeva and her friends like Khryusha the piglet and Styopa the rabbit.Vedeneyeva returned the favor by guesting in Mister Rogers backyard. They didn’t end the Cold War but it was still a significant moment in TV history. Mister Rogers had entered an exclusive zone and overall things went smoothly.Rogers and François Clemmons reprising their famous foot bath in 1993. Photo by Dr. François S. Clemmons CC BY-SA 4.0That isn’t to say there weren’t bumps in the road. Some initial Moscow frostiness was reportedly thawed when Rogers began playing with Daniel the Tiger during talks. And when the crew wanted to film at a Russian doll factory the request was firmly denied.Producer Margie Whitman revealed to the Times, “They told us why we couldn’t go there, and then said that a few months ago they probably wouldn’t have been able to give us the real reason.”Rogers being presented the Presidential Medal of Freedom by President George W. Bush in the East Room of the White House on July 9, 2002.A key reason Rogers was granted permission could have been his relative inconspicuousness. Despite being part of American family life for decades, his profile outside the Land of the Free was pretty low.The Telegraph comments, “in the pre-internet age, even while soap operas, crime shows and sitcoms criss-crossed the Atlantic, children’s programming seldom traveled… Yet Fred Rogers, who died in 2003, was a figure of titanic influence on several generations of American children.”Rogers screens the tape replay with Betty Aberlin and Johnny Costa in 1969.Mister Rogers’ Neighborhood lasted for 912 episodes. The show and its central figure arguably lacked pizazz, though it did have an aspiring performer named Michael Keaton working behind the scenes.“[He] was one of the nicest, authentically good people you’ve ever met,” Keaton said in a 2014 ABC News interview. “Really good dude [with] kind of a sneaky, sly great sense of humor.”In covering Won’t You Be My Neighbor, The Telegraph wrote, “Its subject was a man who, as (director Morgan) Neville tells me, loved dirty jokes but would never tell one himself.”The Fred Rogers Memorial Statue in Pittsburgh, Pennsylvania.Rogers sometimes used his familiar and trusted corner of the Public Service airwaves to highlight important issues. He would keep youngsters up to speed with current events, tackle thorny topics such as death and challenged racism.His legacy has its detractors, with some claiming “the entitlement and rage of the modern American adult is directly linked to Fred Rogers; that he’s the father of ‘generation snowflake.’”For Neville however, he’s a voice the American public needs. He made his documentary to promote that message of dignified conduct to the world. Neville wondered “Where’s this voice in our culture today? Where’s this voice advocating for civility and empathy and these kinds of things which are so rare. It was not a nostalgic instinct at all: it was how do I get this voice into 2018?”Read another story from us: The Real Catcher in the Rye – Factors Which Led to J.D. Salinger’s Life of SeclusionThe forthcoming movie You Are My Friend, starring Tom Hanks as Rogers, should promote the show in a way it never managed back in the day.

Colin Kyrie Irving is officially a flake

first_img Advertisement With LeBron out of the East, the Celtics have the inside track to dominate the conference for the foreseeable future, but recent reports say Kyrie Irving may be mulling over the possibility of leaving Boston when he hits free agency to join the Knicks.Colin has always supported player mobility and thinks Kyrie is an incredible talent, but he thought Irving forcing his way out of Cleveland, away from LeBron, was a mistake. LeBron helped transform Kyrie’s reputation from that of  an oft-injured scorer on a losing team to a top-tier star on a champion. In the end, Irving was more interested in getting credit than staying and winning more titles.Now Kyrie has the best coach in the NBA and a team that is set up to dominate the East, but he would reportedly trade more potential championships for the commercial stardom of playing in New York. Colin thinks Irving splitting from a second title contending team to move to the worst run organization in sports confirms he’s a flake. And the Earth is definitely round, that whole thing doesn’t help.“There are no better coaches than Brad Stevens. The Celtics have draft picks, depth… they’ve got everything.

Cybercrooks Tire of Windows Theyre After Your iPhone Now

first_img Problem Solvers with Jason Feifer Cybercrime is moving away from traditional targets, like Windows PCs, and focusing more on mobile devices, according to Cisco’s 2010 Annual Security Report (PDF). As Microsoft becomes more savvy about patching holes in its OS, cybercriminals are treading into new territories, with a strong focus on iOS and Android.When the federal government declared jailbreaking cellphones legal, intrepid hackers sought and discovered more exploits in mobile operating systems. A prominent example used by Cisco is JailbreakMe 2.0, the Safari-based iPhone flaw — which has since been patched — that allowed users to jailbreak with very little tampering of iOS.Cisco threat research manager Scott Olechowski also said that the proliferation of Android will likely lead to major attacks on Google’s OS in the future. Olechowski noted that the more devices that adopt Android — such as smartphones, tablets, even vehicles — the more enticing the open-source OS becomes, especially when it comes to the big bucks in the enterprise.Most concerning for mobile hacks are apps, many of which access user information without permission.

Tech Startups Are Prodding the Dinosaur That Is the Insurance Industry

first_img Opinions expressed by Entrepreneur contributors are their own. October 21, 2015 Growing a business sometimes requires thinking outside the box. Here’s a sentence you don’t read every day: Insurance is so hot right now.Entrepreneurs and investors have finally woken up to the opportunity in the insurance industry. At $831.5 million, investment in insurance tech this year is already up nearly 10 times what it was in 2010.The opportunity has been staring entrepreneurs and investors in the face for years. The first insurance companies in the U.S. were started in the 1700s, and that cottage industry has grown into one of the biggest markets and sources of capital in the world. Premiums in the U.S. insurance industry total around $1 trillion, or approximately 7 percent of gross domestic product. On top of that, insurance companies invest nearly $7 trillion in assets.And here’s the kicker about all that insurance money — it’s generated by millions of agents, with lots of paper, in processes that look much the same way they did 30 years ago.Related: Investors Are Poised to Disrupt the Tech-Averse Insurance IndustryIn my previous life as a McKinsey consultant, I advised the top insurance companies on projects that were, at their core, incremental. They were always about increasing the productivity of the agent-based sales force, or improving the efficiency of paper-based claims operations. In other words, what I was doing was putting the dinosaur on a diet and prodding it with a stick. What needed to be done was bring a whole new breed of animal into the insurance game.So I left McKinsey in 2013 to do just that and started a digital consumer insurance company, PolicyGenius. At PolicyGenius, we want to do for consumer insurance what TurboTax did for taxes: Make a complex and intimidating financial task easy enough to do it yourself online.While raising seed capital for my insurance tech company last year, the most common question I got from prospective investors was, “Why is now the right time for tech to disrupt insurance?” The obvious answer for those unfamiliar with the insurance industry is the Affordable Care Act, which was signed into law in 2010. The law created exactly the kind of macro shakeup that attracts entrepreneurs. Indeed, since 2010, 56 percent of all insurance tech startups are focused on health insurance, either delivering new employer brokerage models (Liazon, Zenefits, Benefitter), new consumer brokerage models (Gravie, Stride Health) or even new health insurance (Oscar). These startups are pushing the brick-and-mortar incumbents to deliver better services and providing much-needed options to consumers.Beyond the Affordable Care Act, there are other forces at work that have opened the floodgates, allowing creative entrepreneurs to reshape the insurance industry more broadly. These are the market disruptions I see:1. The end of an eraAmericans used to rely on their employers for retirement security. After 20 years of service, you’d get a gold watch and a pension to fund your sunset years. Then, in the 1980s, growing pension costs and a legislative change replaced the corporate pension with the 401(k) and gave rise to the modern retail investment and retirement industry.That shift — from employer to consumer responsibility — is exactly what’s about to happen to insurance. Employer-sponsored insurance is the legacy of an IRS ruling after World War II that allowed employers to deduct employee health insurance as a business expense and employees to receive that benefit as nontaxable income. Sixty years later, we have a sprawling and bloated system, where the extra employer layer adds billions of dollars of cost and empowers employers to make intrusive decisions about their employees’ healthcare. Add to that, the cost of health insurance premiums growing at four times inflation and workers changing employers far more often than they did 60 years ago, and you have a system that’s going to break.The cracks are already showing. The number of workers at small and medium-sized companies who get employer-sponsored health insurance has steadily declined since 2000. The CEO of Aetna has called for the creative destruction of healthcare and taking the employer out of the health insurance equation. Startups that can effectively step into that employer insurance void, the same way companies like Fidelity and Schwab stepped into the employer pension void, will enjoy a massive opportunity.Related: 3 Benefits of the Affordable Care Act Every Business Leader Needs to Know About2. A changing workforceIt’s no secret that the workforce is rapidly changing. The average worker changes employers every 4.6 years. And, more disruptively for insurance, more workers are finding themselves outside the typical employer relationship. Spurred by on-demand services like Uber and countless “Uber for X” startups, freelancers and independent contractors are projected to grow from 42 million people to 65 million in the next 5 years.These workers need individual insurance (like health, disability and life) and business insurance (liability and property). Insurance companies, and the traditional insurance agent model, are ill-suited to serve the self-employed and provide them with the advice and products they need to financially protect themselves and their families.Ask 100 freelancers how they navigate the insurance maze and they’ll all say same thing — with tremendous difficulty. Easing that difficulty for them represents a tremendous opportunity.3. An aging sales forceMost insurance in the U.S. is still sold by human agents, same as it’s always been. But it won’t be for long. The average age of an insurance agent in the U.S. is 59, and one-fourth of the industry’s workforce is expected to retire by 2018. In other words, insurance companies are standing on a burning platform. And they’re already starting to feel the heat.For example, life insurance ownership is at a 50-year low, not because the need has changed — in fact there’s a $20 trillion life insurance gap, but because the agent sales channel can’t reach the modern financial consumer. To their credit, insurance companies realize this reality, but the fact of the matter is that they can’t move as fast as startups can. So they’re investing in startups.  Insurance companies have dramatically increased their direct investments in tech startups to the tune of $1.8 billion since 2010. Much of this investment has gone to the first waves of financial technology: lending (Prosper) and wealth management (Learnvest, Betterment). But talk to any insurance company directly investing in startups, and you’ll learn that they’re hammers in search of nails, that is, smart entrepreneurs tackling the fundamental problems in insurance.4. Unmet needFinally, and most importantly for a mission-driven company, there is a tremendous unmet need for insurance in the U.S. According to a recent survey by the Federal Reserve, 47 percent of households couldn’t cover an emergency expense of $400. Insurance is intended to fill in this savings void for unpredictable emergencies. However, too many Americans have low savings and inadequate insurance, which leads to financial disaster. For example, health problems and disability contributed to half of all home foreclosure filings and over 60 percent of all personal bankruptcy filings. It’s not easy or sexy to sell insurance to middle America, but it’s an important problem to solve — and the first company to do it will be huge.These are the tailwinds that made me excited about insurance tech two years ago and which continue to drive my company forward. We recently closed a $5.3 million Series A round, which included the participation of insurance companies’ venture arms, including AXA Strategic Ventures and Transamerica Ventures. We, and our insurance partners, are excited to make insurance the next big thing in tech.Related: The 25 Best Companies for Employee Compensation and Benefits Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Register Now » 7 min readlast_img read more

First Impressions Count Just as Much Online

first_img Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now September 9, 2016 This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. Opinions expressed by Entrepreneur contributors are their own. Enroll Now for Free There’s a lot of analysis and science that goes into wowing a digital audience. But despite the numerable studies indicating best practices, most website owners just tend to wing it. Not following best practices leads to a loss of traffic and conversion because the harsh truth is that, on average, more than half of your visitors will spend less than 15 seconds on your website. Let’s break down the things that can be done to compel them to stay a little longer.Be visual. Rich, evocative, beautiful, and professional-quality images are the cornerstone of the modern web. As a matter of fact, studies have shown that businesses can increase sales by increasing product image size. Video also has a massive impact on visitors. Adding a video to a landing page can increase conversion rates by 80 percent.Related: 7 Sources of Free High Quality Stock ImagesBe usable.While visual content like images and video are critical, none of these tactics work without a fluid web design. Visitors should find it easy to navigate across multiple pages. It should require almost no effort for them to identify and locate what they need. Be human. The copy used on a website can have an immediate effect on a visitors’ perception. Writing that is clinical, stoic, or “salesy” will tune readers out. In the book Web Copy That Sells, author Maria Veloso described research done on 20,000 pieces of copy that concluded that “editorial-style web copy outpulled sales letter-style web copy every single time.” Copy that appeals to users’ needs, emotions, and sensibilities will be significantly more effective in captivating them. Instead of riddling a site with jargon, corporate speak and pitches, it’s best just to be human. Showcase value proposition by being personable. As an example, Crowdsourcia’s website introduces itself to visitors by using the pictures and names of their team members. This complements copy that is natural, welcoming and friendly.Be valuable.Exciting, valuable and helpful content can keep visitors engaged. Using best practices such as having engaging calls-to-action, encouraging social sharing and facilitating discourse can rapidly convert a stranger on the information superhighway into a brand advocate.Be technical. Digital entrepreneurs put up websites and casually forget that their entire business is being facilitated by technology. They focus on great images, perfect SEO and killer content, but their sites are not secure. They’re also not cross-browser compatible or optimized for mobile, and loading a page takes a million years to complete.Related: 7 Tips for Feeding Your Website’s Need for SpeedBe mobile.Impressing visitors isn’t just about what’s on the page, it’s also how much care is put into its delivery. Back in 2014, it was estimated that 60 percent of all online traffic came from mobile devices. Half of all emails are opened on mobile devices. With mobile continuing to charge past desktop website access, it’s critical to design a site that is perfect for the small screen.Be secure. If a website sells merchandise or requires visitors to share sensitive information, much care should be taken to protect their data. Professional grade sites with expired certificates, security warnings when posting data to a server, and lack of password complexity rules, all can quickly turn a prospective buyer into a ghost. Ensuring a website has undergone a thorough security audit and reinforced its walls can help solidify its professionalism to visitors. Be compatible. Cross-browser compatibility is the bane of most web designer’s existence. That’s because every browser implements a web page slightly differently. There is a standard protocol but small variations in implementation can mean the difference between a stellar layout in Chrome and what looks like stitched tiles in Internet Explorer.Related: How Chrome Won the War of the BrowsersChrome has the largest global market share of all browsers, but the second largest, Internet Explorer, implements an identical website differently. At the very least, these two differing browsers should be fully supported.Be fast.Forty percent of people abandon a website that takes more than three seconds to load. That’s not a lot of time. Speed ensures a smooth experience. The key is that the technical frameworks that enable websites should be nearly unnoticeable, allowing visitors to focus on an organization’s story, value proposition, and content. 4 min readlast_img read more

The Worlds First Robot Police Officer Just Debuted in Dubai

first_img Enroll Now for Free Free Workshop | August 28: Get Better Engagement and Build Trust With Customers Now 2 min read May 22, 2017center_img This hands-on workshop will give you the tools to authentically connect with an increasingly skeptical online audience. From fast food cooks to concierges at restaurants and hotels, robots are slowly infiltrating the workforce in nearly every industry. Most recently, the world welcomed its first operational robot policeman.“Robocop,” the newest member of the Dubai police force, debuted on May 22 at the Fourth Gulf Information Security Expo and Conference, where it greeted guests.Related: These 5 Robotics Startups Are Changing The Way Work Gets DoneAt approximately 70 inches tall and weighing nearly 220 pounds, Robocop seeks to engage with city residents and tourists. Featuring an “emotion detector,” the robot can recognize a person’s gestures and body language from nearly five feet away. Robocop’s skills don’t stop there — the emotionally intelligent bot can detect if a person is happy, sad and even angry by studying his or her facial expression. And just like your human friends would do, if Robocop sees you’re unhappy, it will try to lift your spirits.  More importantly, when it comes to fighting crime, the robot uses the internet of things, artificial intelligence and other smart technologies to spot offenders using facial recognition. Its navigation skills grant it the ability to map out areas and travel on its own.Related: These Absolutely Frightening Robots Will Give You NightmaresEquipped with a built-in tablet, Robocop can communicate with people, speak six languages, respond to public queries, shake hands and even military salute.”With an aim to assist and help people in the malls or on the streets,” said Brigadier-General Khalid Nasser Al Razzouqi, director-general of smart services at Dubai Police, “the Robocop is the latest smart addition to the force and has been designed to help us fight crime, keep the city safe and improve happiness levels.”last_img read more

Find out which version of Android your apps support

first_imgFind out which version of Android your apps support by Martin Brinkmann on October 24, 2016 in Google Android – 1 commentAppChecker – List APIs of Apps is a free application for Android that displays which version of Android each installed application supports.Android is quite the fragmented operating system which can be attributed to several factors. First, it is the pace in which new operating system updates are released, and the — often — lacking manufacturer support for released smartphones and devices.Even Google itself offers only two years worth of upgrades for its devices, and while you may be able to install new Android versions using ROMs, manufacturer support is usually quite bad on Android.The same can be said for applications. Apps have a minimum and maximum Android version they support. That’s the reason why some apps won’t install on your device.Things can also turn out badly if you install a new Android version on a device, as some apps may be incompatible with it or features that have changed.Appchecker Android application compatibilityAppChecker is a free application for Android — with advertisement and in-app purchase offers — that lists the Android version that all user-installed or system applications support.The application is easy to use. Simply install it from Google Play or a third-party repository and run it afterwards.It displays the list of user-installed applications on the device it is run on. Each app is listed with its name and version, and the Android version it has been optimized for. As you can see on the screenshot above, the version can differ significantly between different applications.A TargetAPI that is higher than the one of the Android device, or lower, does not necessarily mean that an application won’t run. It can however be the case that certain features are not supported by the app on the device, or that existing features may not work anymore.Apart from listing all installed applications, you may also list system apps as well. Simply tap on the menu icon and check the “show system apps” option of the menu that opens.There you may also switch to displaying versions as number instead of codenames.Another option that you have is to load a pie chart that highlights the distribution. This is shown on the screenshot on the right. You may use the slider at the top to filter out some versions of Android automatically.How do the stats on my Android device look like? Only 17.4% of all apps have Android Nougat as the TargetAPI, 34.8% Android Marshmallow, and almost 50% older versions of Android. Adding system apps to it, the situation looks even worse. Android Gingerbread (version 2.3 – 2.7) enters the stats, a version of Android released in 2010.Closing WordsAppChecker is a useful application for Android.

How Plastic Straws Slip Through the Cracks of Waste Management

first_imgOK, maybe that logic didn’t work out so well in Nemo. And many cities are pretty far from the ocean. But even inland cities with high-tech combined sewage treatment programs experience some amount of leakage into local watersheds—when a big storm floods the sewers, or a catchment grate malfunctions, for instance. And many pieces of litter skip the sewage system completely, and get blown or washed directly into a stream, lake, or sea.You’ve probably heard the shakily-sourced statistic that Americans throw away 500 million plastic straws each day (an average of 1.5 straws a day per person, if true). Even if that figure needs work, researchers have plenty of other data showing that straws are a pretty big problem. Thanks to the assiduous record-keeping of global beach cleanup crews, a study published in Science in 2015 calculated that America’s beaches are strewn with about 7.5 billion straws.Of course, those straws don’t just stay there. Wind and rain are constantly forcing debris seaward. Once in the waves, tracking the trash once again gets chaotic. “Coastal zones are complicated, where objects get stuck in eddies, washed back onshore, and moved all over the place,” Lippiatt says. Between the waves and the sun—UV light breaks down many chemical bonds—plastic debris takes a beating. It’s during this time in the coastal zone that many straws get broken down into tiny bits. Earlier this year, a three-year-old video of researchers extracting a long, twisted tube from a reptile’s bleeding nostril went viral. To date, it has accumulated more than 30 million views and set off a moral panic.The straw that broke the turtle’s beak also did a number on the camel’s back. Companies like Starbucks, Ikea, and Hilton hotels have announced policies reducing or eliminating single-use slurping devices. Communities in California, New Jersey, and Florida—plus the metropolis of Seattle—have announced policies to phase out or restrict businesses from selling straws. And has there been backlash to the straw bashing? This is 2018, baby, you know there’s been backlash! Some is just normal anti-environmental crankiness. Some is legit: Plastic straws, especially the bendy ones, are essential for people with disabilities.And some of the critique inspires serious head scratching: Disposable straws account for a very small fraction of the total plastic waste that winds up in the oceans, and are pretty unexceptional in terms of ecological impact (Read about fishing gear’s environmental impact if you really want to put your straw concerns in context). So, if straws are just a small part of a big problem, why not just pour all this anti-straw effort into better waste management overall? Well, straws—by nature of their design and ubiquity—are remarkably good at slipping out of the waste stream and into the wild.“I think the fact that straws are small and used on-the-go lends itself to the fact that they can easily leak into the environment,” says Sherry Lippiatt, the regional coordinator for NOAA’s marine debris program in California. The problem isn’t that straws fall below some size threshold that casual litterbugs use to gauge their guilt. Though size-bias is a real thing when it comes to how people feel about litter, the real problem is that straws literally fall through the waste management cracks. Eventually those bits of debris get sucked offshore. From there, figuring out their fate becomes much simpler. Physical oceanographers actually have charts that tell them roughly how a piece of debris will behave once it’s in the ocean. One of the biggest factors is the object’s windage—that is, how far does it stick out of the water, and how much wind will it catch? The other factor is where the object winds up in the water column. Deeper water tends to move more slowly than at the surface. Intact straws and straw fragments are both unlikely to float on the surface, and are probably more influenced by currents than wind. A lot of the ocean borne-garbage winds up in massive oceanic gyres, like the fabled Pacific Garbage Patch.Not all of it, though. A lot of it probably sinks to the ocean floor, and settles in with the abyssal sediment. And, as YouTube showed, many pieces of plastic pirouetting through the ocean get gobbled up by sea creatures—the vast majority of whom will never be YouTube stars.Heart-wrenching videos aside, and Houdini-like propensity to slip out of waste management systems notwithstanding, there’s still the question of whether banning straws is worth the effort. “I’m not sure that straws are exceptional in terms of their impact to an ecosystem,” says Kara Lavender Law, a research professor of oceanography at the Sea Education Association in Woods Hole, Massachusetts. “I think the reason straws have been singled out is because they are a low-hanging fruit. They are something that most of us, though not all, for example some disabled people, children, can easily do without, and by doing so we reduce the amount of plastic trash that is generated and therefore needs to be managed somehow.” Straws may be a small percent of the overall US total—they aren’t even a huge percent of all the small plastic debris that gums up nature’s maw. But a low-hanging fruit is still worth picking.More Great WIRED StoriesReddit goes old school with subreddit chatPhotograph or painting?

Sign up for our daily newsletter and never miss our latest and greatest stories. “Any moment when trash is being transferred from one mode to another, some fraction of it is lost,” Lippiatt says. Between the hand and the garbage can, some slurpers’ straws just miss the connection. And then again, when the trash bag gets removed and put in a bin. Maybe the bag tears on its way into the big bin. Maybe a rat rips a hole because it smelled some half-eaten Taco Bell. Maybe your city installed street receptacles with ridiculously huge slots, such that whenever there’s a big gust of wind, the plastic liner inverts, spewing garbage all over the street (looking at you, Manhattan). Then the trash truck comes. In the process of tossing bags in the back, those workers inevitably, inadvertently, are going to lose some as litter. Especially anything small, light, and easily airborne. Also, straws are plastic, which means many people might mistakenly think they can be recycled. “Something that is often overlooked is peoples’ reaction when they hear about the marine litter problem, they say ‘I don’t litter, and I recycle, so I’m not the problem’,” Lippiatt says. Straws, in fact, cannot be recycled. Recycling plants are big, conveyer-belt driven operations, and straws are so small they just fall off the conveyor belts and onto the recycling plant floors, from whence they are sent to landfills. Another set of bags, another trip in a big truck. Or boat—a huge percentage of US recycling and trash gets shipped away to other countries.Once a straw is outside the bin, odds are it’s going to find its way to water. Weather has an affinity for moving things around, especially those that are round, hollow, small, and light. A city straw might sit in the sticky spot under a trash can for a while, but eventually some wind or rain will probably wash it into a storm drain. “And, as Finding Nemo taught us, all drains lead to the ocean,” Lippiatt says.last_img read more
