first_img Struggling powerhouse The struggling powerhouse, which have already been disqualified from the Copa del Rey for fielding an ineligible player, will also have to be careful not to be caught by fourth-place Villarreal after Bruno Soriano scored his second of two goals deep into stoppage time to grab a 2-1 victory at Deportivo La Coruna. Benitez’s latest stumble, which arrived after losses at home to Barcelona and away at Sevilla and Villarreal in the last eight rounds, came in his return to a Mestalla Stadium where he established his reputation with two league titles and a UEFA Cup trophy. Benitez’s counterpart, Gary Neville, remained winless in his fourth league game since taking over at Valencia, but his team earned a morale-boosting result. Madrid’s strong start provoked panic in Valencia. Bale started the move with an audacious back-heeled flick to send Benzema’s pass to Cristiano Ronaldo, who slid the ball back for Benzema to slot his shot into the corner of the net. But instead of going for a second goal to finish the hosts off, Madrid let complacency creep in, and Valencia slowly began to push forward through midfielder Andres Gomes and forward Joao Cancelo. A Gomes incursion was only stopped when Pepe tripped him in the area, letting Parejo step up and level the score. Madrid recovered some of their attacking verve after the restart, but it was stalled by Kovacic’s sending-off for a lunging tackle on Cancelo in the 70th. Toni Kroos, however, placed a free kick for Bale to rise up and gracefully head in off the far post to momentarily restore Madrid’s lead. But Valencia charged right back to score when Rodrigo Moreno headed down a pass for Alcacer to nod home. Also Sunday, it was Athletic Bilbao 2, Las Palmas 2; Real Betis 0, Eibar 4; Granada 2, Sevilla 1; and Rayo Vallecano 2, Real Sociedad 2. BARCELONA, Spain (AP): Real Madrid squandered a great opening goal and a chance to catch Barcelona in the Spanish league standings when they slipped to a 2-2 draw at Valencia in a match it ended with 10 men yesterday. Madrid seemed set to romp to an easy victory after Karim Benzema finished off a superb move in the 16th minute, but Valencia’s Dani Parejo levelled from the penalty spot just before half-time. Gareth Bale headed Madrid back in front in the 82nd, despite his team playing a man down after Mateo Kovacic saw a direct red card, only for Paco Alcacer to strike right back for the hosts a minute later to spark a thrilling finish by both teams. Coach Rafa Benitez will face even more scrutiny after Madrid failed to capitalise on Barcelona’s scoreless stalemate at Espanyol on Saturday and remained two points behind the defending champions, which have a game to play. Madrid also fell four points behind provisional leaders Atletico Madrid, the only title contender to win this round. Benitez said: “I can’t stop some people from speculating” about his future. “What I can do is get the team to work hard like they did today,” he said. “We missed an opportunity – only if you look at the result. But the effort that my team made deserves more praise that anything else.”last_img read more

Frost [Queen’s University, Ontario].  “For a walking pigeon the small amount of motion during the hold or stabilization phase is less than 0.5 mm.”  This ability involves a complex interaction between the retina, neurons, visual cortex, accessory optic system, vestibular balance system, and the flexible muscles of the neck and the gait of the legs.    The birds with the most remarkable stabilization may live right in your garden.  “Humming birds, hovering in front of a flower while feeding show an amazing ability to keep their head stabilized while their body makes considerably larger movement produced by their wing beats and perturbation by the wind,” he said.  “Kestrels and kingfishers, while hovering in mid-air before diving to catch their prey, also show remarkable stabilization of the head relative to the much larger movements of their bodies.”  Even the heavy flying birds, like geese and swans, do pretty well.  “Films and videos … show that while there is an upward thrust of their bodies produced with each downward wing-beat their heads maintain a nearly perfect level path.”Goggle eyes:  The amazing ability of animals to navigate is a source of ongoing study and experimentation.  James L. Gould [Princeton} started his Dispatch in Current Biology3 with the following expression of wonder:Of all the wonderful things animals can do, the ability of certain species to judge their location on the planet is perhaps the most astonishing.  A homing pigeon transported in darkness 200 km in a direction it has never before been and released far further from the loft than it had previously ventured, will typically circle and then set off in roughly the correct direction.  A migrating bird, captured near the northern end of its annual journey south and carried in the hold of a plane 5000 km east, sets off southwest toward the goal of its migration, rather than either northwest to its natal area or west for the capture point.  The accuracy of this navigation is startling: pigeons fitted with frosted goggles (which eliminate form vision) return to within a couple of kilometers of their loft.  How is any of this possible?The fact is, we don’t fully know.  Is it magnetic fields they sense?  Odors?  Positional cues?  Gould discussed primarily how a popular olfactory hypothesis has been falsified.  Most likely magnetic field gradients are a factor, but work continues to try to understand how any of this is possible.last_img read more

It is “an encouraging return to optimism”, TNS says, after the all-time low of 49% in mid-2008 – shortly after the widespread and brutal pogroms against people from other African countries broke out in May of that year.Download the survey press release (PDF, 118 KB)Since 2004 TNS has surveyed the level of optimism in South Africa every month and, since February 2009, how many South Africans are thinking of emigrating. A sample of 2 000 adults from the countries’ seven major metropolitan areas are interviewed in their homes. The June survey involved 1 260 blacks, 385 whites, 240 coloureds and 115 Indians/Asians, and has a margin of error of 2.5%.In June 73% of respondents agreed with the statement, “I am positive about South Africa and its future”, while 19% disagreed and 8% didn’t know know. The number who agreed were a huge improvement on February’s 60% and May’s 68%. In fact, according to TNS, “there has been an uninterrupted rise since the 56% achieved in November 2008”.In response to the statement “I am thinking of leaving South Africa” an overwhelming 88% said no, with only 12% agreeing and 4% saying that they didn’t know. Thoughts on emigration appear to be relatively unchanged: those thinking of leaving make up a similar proportion to the 11% in February, but those who are not thinking of leaving have risen from 82% to 84%.The only significant drop is in those who are undecided about emigration, which fell from 7% to 4%, which TNS attributes to the results of South Africa’s April 2009 national elections. “It seems that the elections may have crystallised a little more the feelings of some people,” TNS says in a statement.Positive and negativeOptimism levels vary between race groups, but there is an overall improvement across all groups.A total of 84% of black people are positive about South Africa and its future, up from 72% in February. At 46% white people are the least optimistic, but also show a rise from 37% in February, while 61% of coloured people are optimistic, up from 47%, and 63% of Indians and Asians, up from 35%.Negativity has seen a corresponding fall. The breakdown of those who do not feel positive about South Africa and its future is, in each race group, is:Blacks: 9% (15% in February)Whites: 40% (48%)Coloureds: 29% (39%)Indian/Asians: 30% (42%)Of the 19% of South Africans who are negative, 32% are black, 41% white, 19% coloured and 9% Indian or Asian. Among black people, Sotho-speakers had the lowest positive score, at 78%.Men are more optimistic than women, and younger people more optimistic than the old. Optimism levels are at 75% among men and 71% among women; only 56% of those aged 60 and over are positive, compared to 77% of those aged 34 and younger.The wealthy are less optimistic than poorer South Africans, although, as TNS points out, there is a correlation between income and race. The income group with the highest positive score was the lower middle class (living standards measure 4 to 6), of which 82% were positive.There were geographic variations, with people in Soweto and Johannesburg being the happiest, and Cape Town and Pretoria (in the Tshwane Metro) the most negative. But, again, almost all areas showed improvement, except for Bloemfontein, where optimism fell from 70% to 65%, and Gauteng’s West Rand, where it remained unchanged at 65%.Thinking of leavingThere was less change from February to June in those thinking of leaving South Africa, with the proportion rising from 11% in February to 12% in June.The percentage of those in each racial group who agreed with the statement “I am thinking of leaving South Africa” is:Blacks: 12% (9% in February)Whites: 14% (15%)Coloureds: 8% (12%)Indians/Asians: 12% (12%)Unsurprisingly, given that black people make up 79% of South Africa’s population (PDF, 320 KB) and whites only 9%, most of the potential emigrants are black – even though a larger proportion of them among whites. The 12% who are thinking of leaving is made up as follows:Black: 63%White: 23%Coloured: 8%Indian/Asian: 6%In each racial group, those who disagree with the statement “I am thinking of leaving South Africa” are:Blacks: 85%Whites: 79%Coloureds: 91%Indians/Asians: 82%While TNS found no difference between men and women, younger people think of leaving far more than others: 14% of those aged under 24 years say they are thinking of leaving, but only 5% of those aged 50 and over. Nearly a quarter of university students – 23% – are thinking of leaving.Only 10% of those who are positive about South Africa are thinking of leaving, but, surprisingly, only 18% of those who are negative are potential emigrants.“This is somewhat counterintuitive; however, perhaps these South Africans are willing to stay and fight out whatever it is that is making them feel negative about South Africa,” TNS says.Geographic differences are less stark, but follow the pattern of optimism levels. Bloemfontein and Pretoria have the largest proportion of potential emigrants, while the people of Port Elizabeth and Soweto are more likely to stay put.“Although 19% of respondents did not feel positive about South Africa and its future, many more South Africans do feel positive and, even among those feeling negative, relatively few are thinking of leaving the country,” TNS says.“The feelings of optimism have grown steadily and without interruption since December 2008 and have regained their all-time high levels.”last_img read more

first_imgThere are so many practical uses for AR being created that are largely overlooked because they aren’t tied to a large brand promoting a popular product. Virtual mirrors let shoppers try on sunglasses, shoes, clothes, hair styles, make up and other products before purchasing them online or in a store. Mobile browsers let people see virtual tours, valuable government data and, eventually I hope, relevant hyper-local news results and alerts. These are just a handful of the practical uses for AR that will hopefully inundate its future.We also pondered the various things, both technologically and otherwise, standing in the way of AR and a prosperous future with the technology. Many noted the various hardware limitations presented by smartphones and other portable devices, including camera, accelerometer and GPS quality and accuracy. One of the more overlooked hurdles AR needs to overcome is the awkwardness presented by holding one’s phone in front of their face when browsing AR content. The cure for this? Time. AR will likely need a few years to move into the public consciousness much in the same way that Bluetooth headsets did, eliminating the majority of the confusion that surrounded their use. I think, however, that by the time the public becomes more accepting of seeing phones held up in the air, there will likely be a better technology suited for browsing AR content. Examples include fashionable head-mounted displays (HMDs) in the form of sunglasses or contact lenses, which would remove he need to hold a device in our field of vision.What we all agreed on at the summit is that the future of AR looks promising, and the exponential growth of technology should help it expand rather quickly in the next several years. If you would like to learn more about augmented reality, be sure to read up on the top vendors in the space in our report, Augmented Reality for Marketers and Developers: Analysis of the Leaders, the Challenges and the Future. 5 Outdoor Activities for Beating Office Burnout Last Friday, ReadWriteWeb hosted our second unconference event in Mountain View, California as experts from around the world gathered to discuss the mobile Web and its future. One of the hot topics I was eager to discuss going into the event was augmented reality (AR) – a top trend that we are tracking here at ReadWriteWeb. In case you weren’t able to make it out to the summit, here is an overview of the discussions surrounding augmented reality from the event.One of the key things I took away from our discussions of AR at the summit was that large group round-tables can quickly devolve into an argument over what is and what isn’t to be considered “augmented reality.” This has been a conversation I’ve experienced not only when trying to describe the technology to someone unfamiliar with it, but also when speaking with experts in and executives in the field. One company specializing in a specific form of AR riffed that another company, focusing on other initiatives, was “not really doing AR” while the other would argue they were. It would seem that the definition of augmented reality is very broad and more inclusive to some, and narrow and exclusive to others. I tend to fall somewhere in the middle, defining AR as something that can take many different forms but which should not be over used to define fringe examples or offshoot technologies. 9 Books That Make Perfect Gifts for Industry Ex… Tags:#Augmented Reality#web Related Posts center_img As augmented reality evolves, I believe the accepted definition should also evolve to reflect the current state of the technology. The two words, “augmented” and “reality” should not be interpreted for their separate values. The ability to add data to a reality-based location, person, event, etc. does not automatically meet the prerequisites for what I would define as augmented reality. It is the implementation of this data into a visual display that makes it “augmented reality,” rather than “augmented” “reality.”For the purpose of the mobile summit, we tried to focus on AR as it pertained to mobile devices. We discussed the issues surrounding standards and the impending compatibility issues between the various mobile AR browsers on the market. Personally I think the sooner augmented reality content can be standardized into a single markup language, the faster and more efficiently the technology can grow and become more widely accepted.Another way that AR’s acceptance will be accelerated is through publicity and greater awareness. As I’ve mentioned in earlier articles, AR was named a top trend to follow in 2010 by Time Magazine, and is currently being featured in a campaign on the Discovery Channel for their hit show Deadliest Catch. These are big steps forward for AR in that they place the technology in the spotlight in front of millions of eyeballs, but not all of the publicity is positive.Personally I find the proliferation of impractical examples of AR to be a long-term detriment to the growth and acceptance of the technology. Unfortunately, the most popular iterations of AR come in the form of gimmicky promotions for movies, TV shows, cars and other products. While it is good to place the technology in front of large audiences, we are teaching people that AR is nothing but a fun trick. I have no problem with AR being used in toys to enhance playing cards, drone helicopters and the overall toy-buying experience, but when AR does nothing more than provide a cheap thrill, it’s missing the point. AR for the sake of AR is, to me, pointless. 4 Keys to a Kid-Safe App chris cameron 12 Unique Gifts for the Hard-to-Shop-for People…last_img read more

first_imgHe always starts by talking about how no one wanted to buy the delectable fish that was called Patagonian toothfish. But when they changed the name to Chilean Sea Bass, it became a big hit. Words matter.So, zero energy homes it is. I’m OK with that, even if it’s a bit inaccurate (because all homes use energy).The definitionIn the introduction of the DOE report, they write, “A zero energy building (ZEB) produces enough renewable energy to meet its own annual energy consumption requirements, thereby reducing the use of non-renewable energy in the building sector.” As I wrote in my article on the 4 possible definitions, things get a little squirrelly when you start talking about how you’d measure the energy produced and consumed. And a couple of the definitions aren’t actually based on energy; one uses energy costs and the other uses emissions.The two big contenders, though, are whether you base the definition on site energy or source energy. First, let’s just define what these two things are.Site energy – This is the energy used on-site, as measured at the meter. For electricity, just look at the kilowatt-hours you get billed for; for gas, the therms or BTUs.Source energy – This is the energy used on-site plus the energy that went into getting that energy onto the site. For electricity, it’s the kilowatt-hours you get billed for plus the kilowatt-hours of energy that are “consumed in the extraction, processing and transport of primary fuels such as coal, oil and natural gas; energy losses in thermal combustion in power generation plants; and energy losses in transmission and distribution to the building site.” That quote is from the DOE report, A Common Definition for Zero Energy Buildings, released this month.Now, how do you qualify a zero energy building? Using the site energy definition, every kilowatt-hour (kWh) of electricity you import to the site has to be offset by an equal number of kilowatt-hours produced on-site and exported to the grid. Likewise, if you burn natural gas on-site for heat, for example, all the BTUs you burn would have to be offset with an equivalent number of BTUs produced in the renewable energy production system on-site.Using the source energy definition, you have to account for the energy used at the source and in transmission and distribution. Doing the calculations for source energy is a bit less straightforward when the home uses fuels other than electricity.In the new DOE report, they came down on the side of source energy. Here’s their fleshed out definition:An energy-efficient building where, on a source energy basis, the actual annual delivered energy is less than or equal to the on-site renewable exported energy.They also put forth an expanded definition of source energy:Source Energy: Site energy plus the energy consumed in the extraction, processing and transport of primary fuels such as coal, oil and natural gas; energy losses in thermal combustion in power generation plants; and energy losses in transmission and distribution to the building site.I say it’s expanded because they’re including the embodied energy of the fuel burned at the power plant.In addition to this definition, they also define something new called Renewable Energy Certificates (RECs), which they define as “tradable instruments that can be used to meet voluntary renewable energy targets.”If you want to learn more about all this, go to the DOE page on this new Zero Energy Building definition and download the 22 page pdf. They show how to do the calculations, qualify zero energy buildings, and use Renewable Energy Certificates.One of the best things about this paper is this qualifying factor from page 10:The designation Zero Energy Building (ZEB) should be used only for buildings that have demonstrated through actual annual measurements that the delivered energy is less than or equal to the on-site renewable exported energy.It doesn’t matter how it models. What matters is how it actually performs. That’s not exactly a common way of thinking in Washington, D.C., where saying one thing and doing another is a way of life.Calculating the zero energy balanceOf course, you have to define the site boundary, which could be the perimeter of the building or the property line. Any energy that crosses the boundary is counted as delivered or exported site energy.I wrote about these calculations a little bit in my article on the four definitions of zero energy use, but it wasn’t as clear as it could have been. This time I think you’ll get it.The DOE is going with source energy as the basis for zero energy buildings, so let’s see how that works. The first thing you need to know is how to go from site energy to source energy. For that, all you do is multiply by the appropriate conversion factor. The table shown in Image #3 (at the bottom of the page) is given in that latest DOE document on zero energy buildings and come originally from ASHRAE standard 105.What confuses a lot of people is that second line. For example, if a home uses 10,000 kWh per year of electricity delivered to the home, it takes 31,500 kWh of source energy to make that happen. So you might think that if you put photovoltaic modules on your roof, you’d need to export 31,500 kWh of electricity to the grid to offset the source energy of the electricity delivered.Not true! Every kWh that you send to the grid really offsets 3.15 kWh of source energy because that kWh can be delivered to another home instead of the electricity from the power plant, with its 3.15 kWh of source energy. Hence the second line in the table above. Imported and exported electricity both get multiplied by the same conversion factor.Using a fuel like natural gas on-site can be confusing, too, but if you just use the table above, it’s pretty easy. Let’s put some numbers in an example:Imported energy A few weeks ago, I wrote about whether homes that produce as much energy as they use should be called net zero energy or zero net energy homes. Several readers offered up another choice: zero energy homes.I’ve also written in the past about four different ways to define net zero energy (the term I’ve preferred). Now, the U.S. Department of Energy (DOE) has weighed in on both of these debates. Do you know what they decided?The nameThe name of the DOE report is called A Common Definition for Zero Energy Buildings. That gives away their name preference, which they’ve actually been using for a while. They dropped the “net” altogether and assume people will be able to figure out what it means. I’m OK with that. The scientist and grammarian in me wants a more precise term, but I get it.Sam Rashkin, the Chief Architect in the DOE’s Building Technologies Office, has been presenting on clearing up our language in the energy efficiency community for the past couple of years. I just heard him again recently in Chicago, where he gave the closing keynote speech at the 10th annual North American Passive House Conference. Electricity6,000 kWh3.1518,900 kWh TypeSite EnergyFactorSource Energy To qualify as a zero energy building, this home would have to offset 20,177 kWh of source energy. Because exported electricity gets multiplied by the 3.15 conversion factor for electricity, that gives us:E x 3.15 = 20,177 kWhE = 20,177 kWh ÷ 3.15 = 6,406 kWhWhat that means is that you’ve got to produce 6,000 kWh of electricity on-site (renewable only – diesel generators don’t count) to offset the imported electricity and another 406 kWh to offset the natural gas use.Make sense?If you’ve got other energy types or fuels in the mix, you do the same thing. Just pick the appropriate source energy conversion factors from the table and calculate the imported and exported energy numbers.
