Explore further Left out to dry: A more efficient way to harvest algae biomass Researchers from the University of California – Riverside (UCR) discovered that a single layer of carbon atoms arranged in a honeycomb pattern, known as graphene, exhibits far better thermal conductivity than carbon nanotubes. Their results open a new window to graphene applications in electronics, where materials that can manage heat are vital.The group’s results are described in a paper appearing in the February 20, 2008, online edition of Nano Letters.“With the continuously decreasing size of electronic devices, materials that can conduct heat efficiently are rapidly growing in importance,” said the paper’s lead author, UCR electrical engineering professor Alexander Balandin, to PhysOrg.com. “Our work increases the range of graphene applications as the thermal management material in optoelectronics, photonics, and bioengineering.” A material’s thermal conductivity is measured in the units W/m•K, read as “watts per meter per degree Kelvin.” A watt is a unit of power equal to a joule per second and a degree Kelvin is a unit of temperature. The meter is, of course, a unit of distance, since thermal conductivity is normalized to the material’s thickness. Thermal conductivity defines how well a given material conducts heat. For example, the value of thermal conductivity of silicon, the most important electronic material, is around 145 W/m•K if measured at room temperature.Carbon nanotubes have a typical thermal conductivity range of 3000 to 3500 W/m•K. Diamond, another form of carbon, comes in between 1000 and 2200 W/m•K. The single-layer graphene studied by the UCR researchers displayed a thermal conductivity as high as 5300 W/m•K near room temperature. “Graphene is particularly promising as a thermal management material because its superior thermal conductivity is supplemented by plane geometry and good integration with silicon,” added Balandin. The interdisciplinary UCR team, which included research groups of electrical engineering professor Balandin and physics assistant professor Chun Ning Lau, measured the graphene’s thermal conductivity in an unconventional way. The usual contact-based methods for measuring thermal conduction are not appropriate for graphene because it is only a single atom thick. Instead, the group used a noncontact approach: They placed a sheet of graphene onto a substrate with a trench carved out of it, such that part of the graphene sheet was suspended over the trench. They then scattered laser light off the suspended portion and measured the graphene’s vibrational response with a technique called Raman spectroscopy (one of several light-based methods used to learn about material properties).By carefully analyzing the graphene’s Raman spectra – its unique response to the light – and the spectra’s dependence on the laser power, the group was able to extract thermal conductivity data. The entire experimental setup is tiny, with the trench just three micrometers (millionths of a meter) in width.Citation: Nano Lett. ASAP Article, 10.1021/nl0731872Copyright 2008 PhysOrg.com.

Physicists Explain How Human Eyes Can Detect Quantum Effects

first_img Explore further (PhysOrg.com) — By greatly amplifying one photon from an entangled photon pair, physicists have theoretically shown that human eyes can be used as detectors to observe quantum effects. Usually, detecting quantum phenomena requires sensitive photon detectors or similar technology, keeping the quantum world far removed from our everyday experience. By showing that it’s possible to perform quantum optics experiments with human eyes as detectors, the physicists can bring quantum phenomena closer to the macroscopic level and to everyday life. The group of physicists is from the University of Geneva, and includes Pavel Sekatski, Nicolas Brunner (also from the University of Bristol), Cyril Branciard, Nicolas Gisin, and Christoph Simon. In their study published in a recent issue of Physical Review Letters, the scientists theoretically show how human eyes can be used to detect a large Bell inequality violation, which proves the existence of quantum entanglement.As the physicists explain, the key to achieving human-eye detection of quantum effects is to use the process of quantum cloning by stimulated emission. Recently, using quantum cloning, researchers in Rome have experimentally created tens of thousands of clones starting from a single-photon. Then, by amplifying one photon of an entangled pair, the researchers managed to demonstrate entanglement. In order to do this, specific detectors are required, which can distinguish two orthogonal amplified states with a high success rate. Now, what Sekatski and co-workers have shown is that the human eye performs extremely well at the task of distinguishing between orthogonal amplified states. This is a consequence of the eye’s main characteristic, namely as a detection threshold. Below a certain threshold number of incoming photons, the eye remains blind (no light is seen), whereas above the threshold the efficiency (i.e. the probability of seeing) is close to one. In their calculations, the authors also considered the influence of experimental imperfections, such as photon losses, which are inevitable in a real experiment. They found that the setup is surprisingly robust. A strong Bell violation can be obtained even in case of high losses, demonstrating the presence of entanglement. This is a very astonishing feature since entanglement is generally an extremely fragile property, highly sensitive to experimental imperfections such as losses. To solve this apparent paradox, the scientists uncovered a loophole in the system. They showed that a specific multi-photon state could actually behave exactly as the entangled state. Therefore, the high Bell violation actually witnesses the entanglement of the original photon pair, i.e. before the amplification occurs, but not the entanglement between the amplified state and the single photon. Still, the authors show that the amplified state and the single photon are nevertheless entangled, but revealing this entanglement would require more sophisticated measurements. This subtle issue provides a much better understanding of the quantum nature of amplified states, which were recently the subject of a controversy among the scientific community.As the researchers finally note, using human eyes as detectors in actual quantum experiments will face significant technical challenges. However, the possibility of observing quantum effects directly with our own eyes is fascinating. Naked eye observation would bring the observer one step closer to the quantum world.“From our theoretical study, the experimental perspectives appear very promising,” Brunner told PhysOrg.com. He added that, although there will be many technical challenges, Nicolas Gisin’s research group in Geneva has already started working on experiments.More information: Pavel Sekatski, Nicolas Brunner, Cyril Branciard, Nicolas Gisin, and Christoph Simon. “Towards Quantum Experiments with Human Eyes as Detectors Based on Cloning via Stimulated Emission.” Physical Review Letters 103, 113601 (2009).Copyright 2009 PhysOrg.com.

Will Bloom box replace power grid Details on Wednesday w Video

first_img Algae bloom fouls Florida Keys © 2010 PhysOrg.com (PhysOrg.com) — The hot energy news for this week comes in the form of a small box called the Bloom box, whose inventor hopes that it will be in almost every US home in the next five to 10 years. K.R. Sridhar, founder of the Silicon Valley start-up called Bloom Energy, unveiled the device on “60 Minutes” to CBS reporter Leslie Stahl on Sunday evening. Although Sridhar made some impressive claims on the show, he left many of the details a secret. This Wednesday, the company will hold a “special event” in eBay’s town hall, with a countdown clock on its website suggesting it will be a momentous occasion – or at least generating hype. Explore further Sridhar explained that the fuel cells inside the Bloom boxes are made from sand turned into thin ceramic squares, each side coated with a green or black “ink.” A single cell can power about one light bulb, but a stack of 64 of the cells could be “big enough to power a Starbucks,” Sridhar said. In between each disk there’s a metal plate, but the Bloom box supposedly uses a cheap metal alloy instead of expensive platinum. One of Bloom Energy’s early critics, Michael Kanellos of Green Tech Media, noted that researchers have been working with fuel cells since the 1830s. On “60 Minutes,” he told Stahl that, if Sridhar succeeds in making the technology affordable and efficient, there will likely be others that can, too.“The problem is then G.E. and Siemens and other conglomerates probably can do the same thing,” he said. “They have fuel cell patents; they have research teams that have looked at this,” Kanellos said.”What do you think the chances are that in ten-plus years you and I will each have a Bloom box in our basements?” Stahl asked Kanellos.”Twenty percent,” he said. “But it’s going to say ‘G.E.'”Further details on the Bloom box – its efficiency; the materials it’s made of; how much carbon dioxide, water, heat, and other emissions it produces – are still secret. In a blog post Monday afternoon, Kanellos said that he had found a US patent filed by Bloom in 2006 and granted in 2009 that mentions the material “yttria stabilized zirconia” as well as electrodes made of metals in the platinum family – although this doesn’t necessarily mean anything. More information may be revealed at Wednesday’s event, which will feature John Doerr, partner in the venture capital firm Kleiner Perkins, which has provided financial assistance to the company. (Sridhar told Stahl that an estimate of $400 million raised by Bloom so far is “in the ballpark.”) Former Secretary of State Colin Powell, a member of Bloom Energy’s board, is also scheduled to be in attendance.• Join PhysOrg.com on Facebook!• Follow PhysOrg.com on Twitter! More information: CBScenter_img As Sridhar explained to Stahl, the Bloom box is a new kind of fuel cell that produces electricity by combining oxygen in the air with any fuel source, such as natural gas, bio-gas, and solar energy. Sridhar said the chemical reaction is efficient and clean, creating energy without burning or combustion. He said that two Bloom boxes – each the size of a grapefruit – could wirelessly power a US home, fully replacing the power grid; one box could power a European home, and two or three Asian homes could share a single box. Although currently a commercial unit costs $700,000-$800,000 each, Sridhar hopes to manufacture home units that cost less than $3,000 in five to 10 years. He said he got the idea after designing a device for NASA that would generate oxygen on Mars, for a mission that was later canceled. The Bloom box works in the opposite way as the Mars box: instead of generating oxygen, it uses oxygen as one of the inputs.Video: The Bloom box on “60 Minutes.”Although Sunday was the first time Bloom Energy came public with the Bloom box (there’s not even a sign on the company’s building), several devices are already being used by about 20 well-known companies. Google, FedEx, Walmart, eBay, Staples, and others have taken advantage of tax credits to purchase the Bloom boxes, and they’re seeing cost savings in their energy bills. For example, four refrigerator-sized units have been powering a Google datacenter for the past 18 months, using about half as much natural gas as would be required to generate the same amount of energy at a traditional power plant. And at eBay, five units running on bio-gas made from landfill waste that were installed nine months ago have saved the company more than $100,000 in electricity costs, said eBay CEO John Donahoe on “60 Minutes.” Donahoe added that, on a weekly basis, the Bloom boxes generate five times as much power than the 3,000 solar cells that are installed on the roofs of the company’s buildings.

New research provokes more questions about the origin of the moon

first_imgMoon. Photo courtesy of NASA Journal information: Nature Geoscience More information: The proto-Earth as a significant source of lunar material, Nature Geoscience (2012) doi:10.1038/ngeo1429AbstractA giant impact between the proto-Earth and a Mars-sized impactor named Theia is the favoured scenario for the formation of the Moon. Oxygen isotopic compositions have been found to be identical between terrestrial and lunar samples, which is inconsistent with numerical models estimating that more than 40% of the Moon-forming disk material was derived from Theia. However, it remains uncertain whether more refractory elements, such as titanium, show the same degree of isotope homogeneity as oxygen in the Earth–Moon system. Here we present 50Ti/47Ti ratios in lunar samples measured by mass spectrometry. After correcting for secondary effects associated with cosmic-ray exposure at the lunar surface using samarium and gadolinium isotope systematics, we find that the 50Ti/47Ti ratio of the Moon is identical to that of the Earth within about four parts per million, which is only 1/150 of the isotopic range documented in meteorites. The isotopic homogeneity of this highly refractory element suggests that lunar material was derived from the proto-Earth mantle, an origin that could be explained by efficient impact ejection, by an exchange of material between the Earth’s magma ocean and the protolunar disk, or by fission from a rapidly rotating post-impact Earth.Press release (PhysOrg.com) — It’s beguiled watchers since before records were kept, and today still, it fills poets with pensive musings, and scientists with enchanting questions. Where did the moon come from, and how did it get there? The prevailing view is that a planet named Theia entered out solar system and banged into our planet with sufficient force to push some of the molten material from our planet into orbit. Over time, that material coalesced to form the moon. Now, new research from geophysical scientist Junjun Zhang and colleagues, suggests that such thinking might be wrong. In their paper published in Nature Geoscience, they find that in comparing titanium isotopes from both the moon and the Earth, that the match is too close to support the theory that the moon could have been made partly of material from another planet. Earth’s makeup found to be more diverse than previously thought © 2012 PhysOrg.comcenter_img Scientists had already found that oxygen isotopes from the Earth’s mantle and the moon were nearly identical, but that wasn’t enough to put a dent in the theory that a collision with Theia had created the moon because oxygen isotopes from the Earth could have mixed with isotopes from the mass of molten material circling the planet after impact. Now, though, because titanium isotopes are not nearly so easily exchanged, it’s difficult to theorize that the same sort of mixing could have occurred.Most scientists agree that if a planet had smacked into Earth and the moon came about as a result, than the moon ought to be made of some of that other planet as well. Some say the laws of physics suggest it would be somewhere in the neighborhood of forty percent. If that’s the case, why don’t studies of rocks brought back by the Apollo missions show evidence of this other planet?Some suggest the moon didn’t come about as a result of an impact at all, but from parts of the Earth being flung into orbit due to a faster spin than we now have. Unfortunately, there is no evidence thus far to support the notion that the Earth ever spun that fast. Others suggest that perhaps it wasn’t a planet that struck the Earth but an object made of ice, which would have evaporated leaving no evidence behind that it caused a huge chunk of the Earth to be knocked into orbit.And some, despite the new evidence, still cling to the belief that it could have been Theia, if Theia were made of nearly the exact same stuff as the Earth, meaning the isotopes would be the same. The odds for that are pretty slim, but not impossible. Hopefully new research will one day provide us with a definitive answer. Until that day though, it seems we will all have to just keep on musing.

Childhood stress may make women gain weight

first_imgChildhood stress may have a bigger influence on weight gain by women than stress during adulthood, says a study.Interestingly, the study that appeared online in the journal Social Science & Medicine found that neither childhood nor adult stress was associated with weight gain for men. “These findings add to our understanding of how childhood stress is a more important driver of long term weight gain than adult stress, and how such processes differ for men and women,” said one of the researchers Hui Liu, associate professor of sociology at Michigan State University in the US. Also Read – ‘Playing Jojo was emotionally exhausting’The researchers analysed data from a survey of 3,617 people (2,259 women and 1,358 men) who were interviewed four times in a 15-year period.Childhood stress was measured on a range of family-related stressors that occurred at age 16 or younger such as economic hardship, divorce, at least one parent with mental health problem and never knowing one’s father.Adult stress included such factors as job loss, death of a significant other and parental and care-provider stress. The researchers found that women who experienced higher levels of childhood stress gained weight more rapidly than women who experienced less childhood stress. Also Read – Leslie doing new comedy special with Netflix“Change in body mass is a process that unfolds throughout life and childhood may be a critical period for establishing patterns that have a long term impact on women’s weight over time,” Liu said.“Men and women respond to stress differently. It may be possible that women eat more to cope with stress, whereas men are more likely to engage in less weight-related strategies such as withdrawing or drinking alcohol,” Liu added.last_img read more

Iron rods go through masons body as he falls from roof finds

first_imgKolkata: Three iron rods pierced the body of a mason after he fell from the roof of an under-construction building at Champahati area of Baruipur in the South 24-Parganas district on Wednesday morning.The victim, identified as Uday Sardar, was immediately taken to the Baruipur Super-Specialty Hospital by the local people. The doctors in the hospital did not want to take any risk as the patient still had the three iron rods that had gone through the right side of his abdomen. Also Read – Rain batters Kolkata, cripples normal lifeThe victim was then taken to Calcutta National Medical College and Hospital (CNMCH), where a digital x-ray was performed on the patient. It was not easy for the technicians to carry out the x-ray as he had to be kept in a seated posture.The doctors at CNMCH successfully removed the three rods from his body, following a critical surgery that lasted for hours. The patient, however, is still stated to be in a critical condition due to the severe nature of his injuries. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedAfter examining the reports, the doctors at the hospital found that one rod was located near his kidney, while another was close to his intestine. The third one was below his liver.The hospital authorities felt the need of an emergency surgery but there were many challenges before them.A medical board has been formed, comprising 7 doctors including the head of the department of general surgery and the heads of the Orthopedic department, Cardiothorasic department, Neuro surgery and Urology department of the hospital. The medical board was in a fix as the iron rods were nearly 3 feet long. The main concern for the doctors was removing the rods as it could make the patient bleed to death.Senior PWD engineers were asked to rush to the hospital and see if they could make the rods shorter in length by cutting them from both ends, as it would have been extremely difficult for the doctors to remove the rods otherwise.The PWD engineers, however, told the doctors that cutting the rods which had already pierced his body, might damage the organs due to the vibration which will be created.The medical board later started the operation on Wednesday evening, with the PWD engineers inside the OT. A huge quantity of blood was arranged by the hospital authorities before starting the operation.A senior official of the hospital said that the iron rods have been removed successfully.last_img read more

Creating opportunities for underprivileged women

first_imgWomen have come a long way after battling against all odds but still there are women, who are yet to take their first step. Le Meridien, in association with Joining Hands (a non-profit organisation), has come up with a new initiative that will train underprivileged women from economically weaker sections in the national Capital, to become a part of hospitality sector. The women will be trained in various sections within the hospitality sector, which would enhance their chance of acquiring jobs for a better livelihood.  Also Read – ‘Playing Jojo was emotionally exhausting’The training will take place for six months where 25 women will learn the intricacies of different departments under the operational section of the hospitality sector. The sole aim is to help them transform into confident women, who can face all the challenges of life.Nidhi Bhasin, trustee of Joining Hands said: “We are very excited about this initiative- the hospitality industry offers huge opportunities for employment. The sector is manpower intensive and people also good exposure to health, hygiene and general grooming. The women participating in this initiative will inspire other women in their communities and will be drivers of change towards cleaner and healthier communities.” Also Read – Leslie doing new comedy special with NetflixShe added that these women will take back home the lessons taught in this profession and it will instill confidence in them to achieve their goals. Meneka Gandhi, Union minister for Women and Child Development was present at the launch and she emphasised on the need for encouragement.  She said: “The craftsmen of this country carry legacy of unique artworks that are very well known but they don’t know how to adapt to change. This is where we have to step in to help them improve their livelihood.” The course has been designed in such a manner that it will provide a hands-on experience to the women. The students will work in the hotel for experience and be later employed if they’re good at it. For others there will be a placement drive, which will give them opportunities to work in other hotels. When Millennium Post asked about the fee structure, Nidhi Bhasin said: “We’re charging a nominal fee of Rs 300 per month so that the women, who’ve joined the course, do not take this lightly.”Some of the students were present at the launch and they happily spoke about it. “I am excited about this course. Till now we have learnt the basics as the course started in January. We are being taught the basics of English language as well such as the usage of ‘has’ and ‘have,” said Samikhsha, a student of the pilot batch.Talking more about the potential that this sector has, Meena Bhatia, vice president, Marketing and Operations, Le Meridien New Delhi said: “There is a growing need to include women in the organised sector and the hospitality industry offers great opportunities for women to join the work force. In my experience, women do exceedingly well in the key areas of housekeeping, food and beverage service, food and beverage production and the front office.last_img read more

Drawing a unique connect Hills celebrate Tiwar with religious fervour

first_imgDarjeeling: The unique festival of “Tiwar” commenced with “Kak Tiwar” on Monday in Darjeeling and Kalimpong.Dipawali is celebrated in a unique way in Darjeeling. The 5 days of “Tiwar” or “Yamapanchak,” is commemorated in the honour of “Yamraj” — the mythological Lord of Death. The first day of Tiwar is Kak Tiwar, dedicated to the crows, believed to be the bird associated with Yamraj. On this day food is left on rooftops and open spaces for the crows. Also Read – Rain batters Kolkata, cripples normal lifeThe next day is Kukur Tiwar. On this day marigold garlands are put on dogs with vermillion being applied on the forehead of dogs. The dog is offered a sumptuous meal. Even stray dogs are not left out on this day and people offer food to them as well. The third day of Tiwar, which falls on the day of Dipawali, is commemorated as Gai Tiwar. Early in the morning, the cows which symbolise goddess Lakshmi are worshipped. The houses are painted and marigold garlands are put on doors to welcome Goddess Lakshmi. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedIn the evening after Lakshmi Puja, tika is annointed on the forehead of seven small girls as they are worshipped as the forms of Lakshmi. Diya or lamp is lit in the main altar of the house. Along with the diyas, copper vase called Gagri is kept filled with water and decorated with flowers. Several groups of girls dressed in traditional Gunue Cholo sit outside the main entrance of houses and sing the traditional “Bhailo.” The next day of Gai Tiwar or Laxmi Puja is the Goru Tiwar — the day dedicated to the ox. In the evening “Deushi” is sung by groups of boys wearing traditional “Daura Suruwal” and playing traditional musical instruments, madal, chyabrung and jhyamta. The five-day Tiwar concludes with “Bhai-Tika.” Both Bhailo and Deushi are forms of folk culture. Both have got a common mythological background. According to mythology, during the Satya Yug, Lord Vishnu in the form of a dwarf had asked for alms from King Bali. King Bali was renowned for his charitable nature. Keeping his word, King Bali gave away his kingdom to Lord Vishnu. The girls of his kingdom fearing destruction, in groups, prayed to Goddess Lakshmi to bestow the kingdom with riches so that its lost glory could be regained. “I do not usually return home during Dussehra but try my best to get leaves for Tiwar. The festival is fun-filled and I love playing Deusi with my friends. It’s also about a sumptuous traditional spread including “Sel Roti” (traditional sweet bread) and different types of “Aachar”, stated Avisekh Bagdas who works in Delhi.last_img read more

5 smart resolutions for the New Year

first_img1. Save more, spend less (and pay bills on time) A no-brainer really, but easy to say and tough to do. Check your past spends and work out how much you want to save each month. Allocate part of your income automatically so you’re not tempted to use the money elsewhere. This could be in an auto-sweep fixed deposit, a SIP in a mutual fund or a transfer to another bank account. Use a money management app to track your spends, create a budget and get reminders to make your bill payments on time. Also Read – Add new books to your shelf2. Clear high-interest debtDo you have several credit cards that are maxed out to the available credit limit, and are you paying only the minimum due each month? If so, you are headed for financial disaster. If you have multiple credit cards, give them up and keep a maximum of two, with the highest credit limit. Avoid any fresh spends on your cards till dues are cleared. List all your debts, from highest to lowest, and clear them in that order.3. Health is wealth – insure it Also Read – Over 2 hours screen time daily will make your kids impulsiveBeing healthy and fit is the best gift to yourself and your family and dependents. Cut down on wasteful spending and eating/drinking, make actual use of that gym membership, get a complete health check-up done and make it a yearly habit.Set aside money each month for an emergency fund worth 6-8 months of living expenses to see you and family through any medical emergency. Regardless of whether you are single or have a family, get a life and health insurance policy so that you/your next of kin don’t suffer financially if something happens to you. 4. Documentation and nominationSounds boring, but it is a good idea to ensure your spouse/family is aware of your finances – not just investments and insurance, but also debts. Likewise, while opening a bank/demat/mutual fund account, not many pay attention to adding a nominee – or in case of a life insurance policy, updating beneficiary from parents to spouse. Documentation can be further split into financial/debt, health/life and legal (if applicable). Ensure it is easily accessible to next of kin in case something happens to you, so they are spared the running around and unnecessary paperwork.5. Remember to have funWorking 9 to 6 daily, five (or six) days a week can take a toll of your health and personal life. Make a conscious effort to set aside time for your family and friends. Plan mini-breaks every quarter and a full-fledged vacation once a year.Do something that makes you happy, take up a new hobby, travel somewhere you’ve never been before – all these will help you refocus and realign your goals and priorities.ianslast_img read more

LeBron fires off notsosubtle subtweet at Dan Gilbert after GM David Griffin

first_imgThings are a mess in again in Cleveland again, and it’s all because of Dan Gilbert, again. If they don’t manage to swing a deal to land Jimmy Butler or Paul George, things could come crumbling down in fast, starting with LeBron taking his talents to the West Coast.Comic Sans Dan strikes again. Here’s his statement re-imagined in his favorite font. In a span of minutes last night, the Cavs went from closing in on a blockbuster trade for Jimmy Butler to complete chaos when they released a statement from owner Dan Gilbert that the organization would not renew the contract of GM David Griffin.According to multiple reports, LeBron James was upset that Griffin was let go without his camp being consulted. He had previously advocated for extending Griffin’s contract.As he likes to do, The King of subtweets fired off a pretty obvious shot at owner Gilbert, passive aggressively thanking Griffin:If no one appreciated you Griff I did, and hopefully all the people of Cleveland! Thanks for what u did for the team for 3 yrs! We got us 1?— LeBron James (@KingJames) June 20, 2017last_img read more

VIDEO New footage of LaVar Ball playing basketball raises further doubts he

first_imgLaVar Ball once claimed he could beat Michael Jordan and LeBron James in a game of one-on-one, but a viral video of him actively sucking it up in an old rec league game got him laughed at by everyone with an internet connection. Now there’s some new footage, albeit brief, of LaVar showing off his “game” in a parking lot one-on-one duel with Lonzo’s manager Darren Moore, and it’s not pretty either. In the short clip, LaVar does actually make a deep jumper, but he also flips up a weak, awkward post up that will give you a laugh. If he has trouble taking down Darren Moore, it’s tough to see him handing his Airness an L.last_img

Three NeedtoKnow Technology Trends for 2011

first_img 4 min read Growing a business sometimes requires thinking outside the box. For small businesses, the new millennium has arrived about a decade late. The big year for innovation was supposed to be 2001, when things like artificial intelligence and a worldwide-networked office were said to be to coming to market. But it has taken an extra 10 years of digital toiling to make some of these tools a reality.In 2011, small-business owners will face a staggering array of new technologies and services. These won’t be for-geeks-only stuff. These are mainstream business systems from the tech giants — tools you may want to consider adopting or you could get left behind.Here are my thoughts on the top business technology trends for 2011. You’ll need to be familiar with these if you want to stay on the cutting edge of your market.1. The Web on your phone might be as fast the Web in your office. The biggest game-changing tool for 2011 is a new generation of fast wireless cellular standards known as 4G. By midyear, most mobile consumers will be able to receive service that’s similar to the robust, plugged-in Web access found in an office. All the major phone carriers will be offering it, including Verizon Communications Inc., Sprint Nextel Corp., AT&T Inc. and T-Mobile USA Inc. Look also for offerings from start-ups, such as Antelecom Inc., Clearwire Corp., Xanadoo Co. and Towerstream Corp., and from cable companies like Comcast Corp. and Time Warner Cable Inc.However, coverage is likely to be spotty and comparing plans could be a struggle, at least in the early days. The cost may be as high as $60 a month per employee and sharing a Web connection won’t be an option. But those willing to brave the trials of moving to a technology early may not only be able to say goodbye to their existing data provider but they may never again need a hard-wired Web connection. The mobile business race really begins in 2011.2. Day planners won’t just track your schedule. Starting next year, smart Web-based business-automation tools will find their way into business software and begin offering opinions on everything from how you should manage tasks to how you arrange meetings and budget projects. Already, Google is adding a sophisticated feature to its Gmail Priority Inbox email services that is designed to help users sort emails in order of their importance. Companies such as Intuit Inc. are adding financial modeling tools to QuickBooks and Mint.com that are so sophisticated that they can guess when you will lose money.Startups are also offering tools to help firms write documents and create content. The leader now is StatSheet Inc., a Durham, N.C.-based technology company that specializes in sports content. In October, it introduced a Web-based service that automatically creates legible articles, analysis and data with nearly no direct human involvement. What does that mean to you? For better or worse, you may soon face the daunting prospect of managing memos and business correspondence that, in some ways, write themselves.3. Work life might be controlled by the touch of a finger. Call it the iPhone effect for businesses. A new generation of Apple Inc.’s iPad-inspired, touch-controlled work tools will go mainstream in 2011.A range of office standbys from printers to desktop PCs will add iPhone-like touch-pad controls. A slew of touch-enabled kiosks, displays and machine controls will be cheap and widely available.The effects are likely to be profound. Touch-enabled screens, just like on iPhones, will allow for a wide swath of new features and functions to be built into just about any business device. Printers will not only connect to the Web but will also produce custom news feeds. Touch-enabled PCs will support both traditional office software and sophisticated inventory and business-management tools that once required pricey custom hardware.Aggressive first movers are already making an impact. For example, San Francisco-based Touch Revolution is developing a line of mobile-phone savvy touch-enabled control modules that are being adapted to everything to office systems to kitchen appliances.By this time next year, your fingers may not only do the walking around the office. They may do the talking as well. Free Webinar | Sept. 9: The Entrepreneur’s Playbook for Going Global Opinions expressed by Entrepreneur contributors are their own.

A Startup Brings HighTech Sports Analytics to School Teams

first_img 3 min read July 15, 2013 Enroll Now for Free Computer engineer Vasu Kulkarni, a lifelong basketball fanatic, had no luck getting his dream job with Nike or the NBA after graduating from the University of Pennsylvania in 2008. But he knew he wanted to stay “connected to the game of basketball.” He found that connection in 2009, when he launched Krossover, a company that set out to bring high-tech sports analytics to high-school and college athletics.It’s a Saturday-morning ritual for student basketball teams everywhere: gathering to watch the film from Friday night’s game. While coaches may pinpoint mistakes, and players may zero in on their own failures or successes, few high-school and college athletic programs have the technology to make full use of those films the way professional teams can.Scoring big: Krossover’s Vasu Kulkarni.Photo© David JohnsonThe online video and analytics platform from New York City-based Krossover bridges this technology gap. Coaches upload video after a game; within roughly 24 hours, it is analyzed and indexed by four Krossover employees, who tag hundreds of plays for each athlete, such as shots, steals, rebounds, assists and fouls. Later the coach can access the game video on Krossover’s site and sort through stats, choosing to view, for example, the number of rebounds achieved by the center. Players, meanwhile, can use Krossover to splice together all their dunks in one video file and share it with whomever they like.In 2010, while peddling a crude prototype of his product at U.S. basketball camps, Kulkarni met one high-school coach whose team had lost 63 games in a row. The coach signed on for Krossover, and after using the product for one season, his team came within one game of the Massachusetts state championship. “Stories like his have helped us to show that there’s a competitive advantage to using our product,” Kulkarni says.Packages start at $799 per season; added services include the option to cut turnaround time and to provide stats on the opposing team as well.Last year Krossover pulled in more than $3.5 million in angel funding to expand its service to cover lacrosse and football in time for the 2013 season. Many investors, Kulkarni says, are attracted to the inherent “sexiness” of sports businesses. “While a lot of traditional technology VCs shy away from sports, most professional investors have some sports connection–they played in high school or college, or they have kids playing,” he explains. “Being involved in a sports business is fun.”Greg Cangialosi, CEO of Nucleus Ventures, invested in Krossover individually and then brought Kulkarni to his home base of Baltimore to organize a round of funding with other local angel investors.”I was impressed with the product and the market,” Cangialosi says. “There are 250,000 sports teams that could use Krossover in high school and college. And Vasu is impressive. He has the ability to get things done, or what a lot of investors call ‘the hustle.'”Sounds like the kind of player any coach would want on their team.

HTC CoFounder Cher Wang to Take Some Duties From CEO

first_img Opinions expressed by Entrepreneur contributors are their own. Attend this free webinar and learn how you can maximize efficiency while getting the most critical things done right. 2 min read A workload shift at HTC will increase the duties of co-founder and chairwoman Cher Wang as the company focuses on regaining market share.Wang will take on operational duties for the Taiwanese smartphone maker, and CEO Peter Chou will lessen his load at the company to focus on innovation, according to the Financial Times.In what is being touted as a temporary move, Wang will expand her day-to-day presence from two to six days a week to work on sales, marketing and supplier relationships, according to the FT. Chou, who has served as the company’s CEO for nearly a decade, will concentrate on product development.“I have become very focused in the past couple of months. Before that I was too busy,” Chou told the FT. “I took on too many things. I need to be more focused on innovation and [the] product portfolio.”Related: HTC’s Cher Wang on Innovation and the ‘It’ Product It’s been a rocky period for the company. In October, the smartphone and tablet maker reported a bigger than expected quarterly loss. It was the first quarterly loss for the company since going public. Some wondered if Chou would stick around but, in June, he reportedly said he had no plans to leave HTC.Earlier this year, the company introduced the HTC One, a smartphone expected to be a competitor to Apple and Samsung mobile devices, but failed to make a huge dent in the market.Last year, Wang spoke to Entrepreneur.com about staying ahead of trends. “We must always keep an eye on our environment, to keep track of what changes are happening in technology, in infrastructure, in markets, in how people across the world are living their lives, working and communicating. We need to anticipate these trends and innovate to meet them. Within HTC, hundreds of ideas are tested and discarded to find those rare ideas that define the HTC user experience,” she said.
