19 March 2012 Cape Town and Table Mountain worked their magic on a group of journalists from the United Arab Emirates (UAE), who visited the country last week as guests of Brand South Africa. The agency responsible for marketing South Africa abroad regularly brings groups of foreign journalists to the country to help build relationships and change perceptions of the continent. Fresh from an informative few days in Johannesburg, and keen to sample the famed delights of the Cape, the group had two days in the city to network, gather information and, of course, fit in some sightseeing. On day one, Tuesday 13 March, the weather in the morning was glorious – sunny blue skies, a light breeze and temperatures that Capetonians consider on the hot side – at least hot enough to hit the beach and dive into the cold ocean. Calling the Gulf states your home, though, means that 33 or so degrees is “comfortable”, in the words of Bahaa Alawam, a Syrian journalist working out of the Gulf.Gulf Co-operation Council He was joined by Mahmood Saberi of Gulf News, a Dubai publication; Peter Smith of Dubai Gulf Business; Hala Saqqa, a senior account executive at Hill and Knowlton Strategies in Dubai; and Roger Romanos, a senior editor at the Al-Iktissad Wal-Aamal Group. The plan was to spend the morning at presentations indoors, with the Department of Trade and Industry. On the agenda were South Africa’s industrial policy, priority industry sectors, and Gulf Co-operation Council (GCC) exports and agri-processing businesses that export to the UAE/GCC, namely Western Cape fruit and juice exporters, beef and fishing, fruit and vegetables, processed foods, and franchising. The next item on the itinerary was a trip on the cableway up Table Mountain. Cape Town’s weather, however, is nothing if not fickle. By noon the wind had picked up and by 1pm the clouds were cascading over the southern side of the mountain. By 2pm the cableway was closed for the day as the wind howled and clouds poured over the mountain and down the gorges. On the upside, the group did get to see her dressed in her famous tablecloth.‘It was beautiful, spectacular’ Instead of the planned trip, energetic tour guide Irwin Horsban of Kaylin Tours packed the group back into the bus and took them on a memorable drive down Kloof Nek and into Camps Bay, on the western side of the Cape peninsula. A stop for lunch and refreshments on the beachfront was a real treat, said Saberi. Romanos, who is originally from Lebanon but has been working in Saudi Arabia for six years, agreed. “What a fantastic place,” he gushed. “It was beautiful, spectacular.” On the way back to the hotel the ever-affable Horsban took the group on a detour through the Bo-Kaap, with colourful houses and history, followed by a splendid seafood dinner at the popular V&A Waterfront that was variously described as “good”, “delicious” and “expensive”. Wednesday – and Mother Nature came out to play, offering a glorious day without a breath of wind. Again, the morning was taken up with presentations and information-sharing, this time at the Oil and Gas Expo.Table Mountain’s 360° views The historic Robben Island was on the agenda for the afternoon, but everyone opted for the mountain instead. Walking on one of the new seven wonders of nature trumped heritage. The cableway was open, and cars were parked for several kilometres down the winding mountain road. But with tickets pre-booked online and a taxi ride to the cableway station there was little delay before the group was ushered into the large and airy cable car. The car takes 65 people at a time, which can be a bit of a squash. There is no need to hog the windows though, as the floor rotates during the ascent, giving each passenger a 360° view. Romanos spoke about investments. His company organises conferences between businesses, and he believes there is much scope for the two regions to work together. “Arab businesses are looking for opportunity,” he said. When the group stepped out at the top the views took their breath away, and they spent a good two hours wandering around, taking pictures and marvelling at the cute dassies, or rock hyraxes – the little animals are closely related to the elephant. “I am half-way between happy and depressed,” said Saqqa, “happy to be here, but depressed that soon I have to return to civilisation.” Her sentiments were shared by the other members of the group. Smith said: “I see Johannesburg is for business, but Cape Town is more for pleasure.” There was time for some cold refreshments before a walk on the white sands of Camp’s Bay beach and dinner at a traditional restaurant in the city bowl. “We are sad to go, but have enjoyed our time here,” said Alawam.

Why Tech Companies Need Simpler Terms of Servic… 8 Best WordPress Hosting Solutions on the Market ArduinoArduino is an open-source electronics prototyping platform made up of open source hardware and software. It’s intended for artists, designers, hobbyists and anyone interested in creating interactive objects or environments. For an example of the type of internet-connected object you can build with Arduino, check out this presentation where the author configured a child’s toy ray gun to react when anyone posted the #barcampliverpool hash tag on Twitter. A Web Developer’s New Best Friend is the AI Wai… 2009 has been a turning point for the Internet of Things, when real world objects (such as lights, cars and packages) get connected to the Internet. This trend has added a significant amount of new data to the Web, so for that reason alone it is an important development. Having said that, many of the following top 10 list are not yet mainstream products. But we expect some of them to become well known over the coming years. Underlying the Internet of Things are technologies such as RFID (radio frequency identification), sensors and smartphones. Now let’s look at the 10 products that stood out this year.ReadWriteWeb’s Best Products of 2009:Top 10 Mobile Web ProductsTop 10 Consumer Web AppsTop 10 Semantic Web ProductsTop 10 International Web ProductsTop 10 RSS & Syndication TechnologiesTop 10 Enterprise ProductsTop 10 Internet of Things ProductsTop 10 Real-Time TechnologiesTop 10 Startup ProductsTop 10 Web Platforms Fedex SenseAware International courier giant Fedex released a new tracking device and web service for packages in December. Called SenseAware, it keeps tabs on the temperature, location and other vital signs of a package – including when it’s opened and whether it was tampered with along the way. Fedex is running a trial period of about a year with 50 health care and life science companies, for tracking delivery of surgery kits, medical equipment – and even live organs.HP CeNSEHP Labs has joined the race to build an infrastructure for the Internet of Things. The giant computing and IT services company recently announced a project that aims to be a “Central Nervous System for the Earth” (CeNSE). It’s a research and development program to build a planetwide sensing network, using billions of “tiny, cheap, tough and exquisitely sensitive detectors.” The technology behind this is based on nano-sensing research done by HP Labs. The sensors are similar to RFID chips, but in this case they are tiny accelerometers which detect motion and vibrations.Japan’s Suica Card and Hong Kong’s Octopus Card Earlier this year we looked at three of the world’s leading RFID-powered Smart Cards: Japan’s cutting edge Suica Card, London’s Oyster Card and Hong Kong’s long-running Octopus Card. In Japan and Hong Kong, the cards (and other devices, such as phones and watches) may be used to purchase goods from selected shops. It’s more pervasive in Hong Kong, where the Octopus can be used at more than 1,000 merchants. Furthermore, in Hong Kong the card can be used as an access device for places like apartment buildings and schools.Mir:rorMir:ror is a device from French company Violet that detects the objects you show it and gives them powers. As you wave a device over the USB-attached mirror, you can trigger applications and multimedia content automatically. The “magic” mirror isn’t actually sensing the object itself, but is reacting to an RFID tag placed on the object which then tells your computer what to do. Those tags are embedded in the company’s Ztamps, colorful RFID stamps that you stick on the objects you want to connect. They also work with the company’s other more well-known internet-connected object: the Nabaztag, an adorable rabbit that can deliver anything from ambient information through lights and sounds to verbal information – like when he reads your email or RSS feeds to you. Unfortunately, in August Violet filed for bankruptcy. However, in October it was saved by videogame publisher Mindscape. WideNoise The iPhone is a fertile ground for Internet of Things, as a product called WideNoise shows. WideNoise is an iPhone application that samples decibel noise levels, displaying them on an interactive map. With the app you can take a sound reading, and if you so wish share that with the WideNoise community. You can check the average sound level of the area around you, which might be handy if you’re house-hunting or simply looking for a quiet spot to relax in.ioBridgeioBridge is a web platform for remote control and monitoring, which bills itself (with tongue in cheek) as “one step closer to Skynet.” It’s a company based in Gainesville, Florida, born because the founders saw “a demand for interfacing real world devices with the web.” Their first beta release was in November 2008 and since then the company has been busy building out its product line and watching what developers like Matt Morey do with them. Morey, who by day is an engineer for Texas Instruments, has developed a two-way, home automation application using Twitter and ioBridge.CitysenseSense Networks is a company aiming to index the real world “using real-time and historical location data for predictive analytics across multiple industries.” It has a platform called Macrosense that “receives streaming location data in real-time, analyzes and processes the data in the context of billions of historical data points, and stores it in a way that can be easily queried to better understand aggregate human activity.”The company has so far built one consumer product on top of this platform: Citysense, an iPhone and Blackberry app that allows people in San Francisco to see the most-happening nightlife in real time. Citysense currently accesses cell-phone and taxi GPS data from about four million GPS sensors, to see where the local hot spots are. It then links to Yelp and Google to show what venues are operating at popular locations.Those are our picks for the top 10 Internet of Things applications of 2009.

Pronounced “PATCH-bay,” Pachube lets you tag and share real time sensor data from objects, devices, buildings and environments both physical and virtual. According to founder Usman Haque, Pachube is about “environments” more so than “sensors.” In other words, Pachube aims to be responsive to and influence your environment, for example your home. For more on this innovative company, see ReadWriteWeb’s three-part analysis of Pachube:Pachube Adds Real-Time Notifications – More Power to The Internet of ThingsApplications From The Internet of Things – An Analysis of PachubeBusiness Models of The Internet of Things – An Analysis of Pachube’s Open Source PlatformIBM’s sensor solutions One of the leading big companies in the Internet of Things is IBM, which offers a range of RFID and sensor technology solutions. IBM has been busy working with various manufacturers and goods suppliers this year to introduce those solutions to the world. For example, IBM announced a deal at the end of June with Danish transportation company Container Centralen. By February 2010, Container Centralen will begin using IBM sensor technology to enable companies in the horticultural supply chain to track the progress of shipments as they move from growers to wholesalers and retailers across Europe. It makes the travel process very transparent and data centric.
HVAC Ducts and AccessoriesMini- and Multi-Split-Systems Mount the unit lower on the wall, or directly on the floorWhile the indoor units of ductless minisplits are usually mounted high enough on the wall to keep them out of the way, there’s no reason they can’t be lowered, GBA senior editor Martin Holladay points out. He includes a photograph of a unit mounted on an interior wall at roughly knee-height (see Image #2, below.). RELATED ARTICLES Factoring in higher static pressureA complicating factor for Goodwin is how well these units would fare with high-efficiency air filters (those with high Minimum Efficiency Reporting Values, or MERVs). “We’d like to use something pretty high performance for dust as well as allergies,” Goodwin says. “What about something like the Trane XV20i, which is variable capacity?”Goodwin doubts the unit would ever run near its two-ton (24,000 Btu/hour) rating, but it might be better prepared to handle higher static pressures that high-performance filters would create.“Would running it at the low end on its rated capacity, using the variable-speed compressor, be less efficient?” Goodwin asks. “Would it have a negative effect on its life expectancy?” Avoid systems that are grossly oversized“In general,” Dorsett replies, “modulating systems run at highest efficiency when modulating at or near their lowest speeds (effectively making the coils oversized for the amount of heat they actually need to exchange). So if your average heating load is around the minimum-modulated output, it can work out well, but if your peak load is below its minimum modulation, it becomes very sub-optimal.”When average loads fall below the minimum modulated output, he says, the system begins to lose efficiency to standby power use and surges in power consumption at startup and short-cycling. Similarly, minisplits that are more than 1.5 times as big as they need to be to meet peak loads will see a loss of efficiency, while below that they will operate at near optimal efficiency.He suggests that Goodwin take a look at the Lenox XP25 or the Carrier Greenspeed.Keep in mind, though, Dorsett adds, that they’re more expensive options than “right-sized” ductless systems and come with distribution losses that ductless systems don’t have.Further, adds Semmelhack, Goodwin should be able to use a high-MERV filter in any of the low-static minisplit systems on the market.“Again,” he writes, “it’s a matter of system design/installation, and carefully accounting for the various parts of the system, including filters.” Ductless Minisplit Heat Pumps Just Two Minisplits Heat and Cool the Whole HouseInstalling a Ductless Minisplit SystemPutting the Duct Back in Ductless Its location might mean an occasional sore shin, but filter changes would be a snap.Or, adds Dana Dorsett, choose a unit designed for installation on the floor. They look like small wall furnaces, he says, and like fin-tube convectors for hydronic heating systems most ductless floor units circulate air from the front face.“They are easily set into walls or cabinets with the face pretty much flush with the wall,” Dorsett says. Mitsubishi, in fact, publishes directions for embedding one of their units in a wall in such a way that its efficiency is unimpeded.Fujitsu website includes specs for a universal floor/ceiling unit that can be mounted on the floor or just high enough on a wall to get a vacuum cleaner underneath. It can also go right on the ceiling, and the cabinets are just under 8 inches deep.John Semmelhack refers Goodwin to a ducted Mitsubishi Mr. Slim model. GREEN PRODUCT GUIDE A two-ton unit would be much too bigAlthough Goodwin has yet to pin down heating and cooling loads, he describes a house with 2×6 walls filled with blown-in cellulose plus 2 3/4 inches of rigid polyisocyanurate insulation, an attic with 20 inches of cellulose, and insulation in both the foundation walls and floor.Given these parameters, Dorsett adds, the heating load should be less than 20,000 Btu/hour, and could be less than 15,000 Btu/hour with good windows. This, he says, makes a two-ton, high efficiency ducted heat pump “a bit silly.”The Fujitsu 18,000 Btu/hour model would more than cover Goodwin’s needs. An alternative would be a pair of floor units connected to a common compressor.A dual-head unit might not be quite as efficient as the “best-in-class perfectly implemented” two-ton ducted model, but the installed cost would be less than half. Goodwin could spend the difference on rooftop solar, which would probably pay for most or all of the heating and cooling bill. Ductless minisplit heat pumps have gotten many favorable reviews at Green Building Advisor, but Roy Goodwin sums up a concern that’s popped up more than once: Despite their virtuoso heating and cooling performance, they’re a little on the homely side.“My wife and I are 69,” Goodwin writes in Q&A post at GBA. “We’re in the process of designing a house for our retirement with our architect. It’s going to be a ‘pretty good house’ with a very small heating/cooling load. Neither my wife nor I think the ductless minisplits are all that attractive.”In addition, Goodwin adds, the air filters on a wall-mounted head could be a challenge to change because of their location. Ceiling-mounted ducted minisplits look like they’d present similar challenges and require a step ladder for filter changes. That’s something they’d like to avoid.Their 2,000-square-foot house will be built in the mountains of western North Carolina in Climate Zone 4. “We’re looking for something like a conventional heat pump (ducts and all) with air filters that are easier to access,” Goodwin says.Any suggestions? That’s the topic for this Q&A Spotlight. Our expert’s opinionWe ran this one by Peter Yost, GBA’s technical director, and here’s what he had to say:I am going to focus on the aesthetics of interior head in my response, just because people’s perceptions when it comes to technology fascinate me.So, I sent out the following email to about a dozen or so colleagues and friends with the photo that you see at the top of the column:Subject: Your input, please?This may seem “mysterious,” but please take a look at the attached photo and reply to me with whatever aesthetic considerations come to mind from the image.When you reply, THEN I can share with you the nature of my request. Nothing scary, embarrassing, or illegal, and there are no correct or incorrect replies. All is relevant and correct, whether positive or negative in nature.Thanks much – PeterYou can see that I was trying hard not to prejudice the issue of minisplit head aesthetics. When subjects of this “survey” responded, I sent them this followup e-mail:I have been asked to comment on a Green Building Advisor blog in which an older couple thinks that the interior minisplit head (that white box on the right-hand wall is a conditioned air delivery system) looks homely.So, I thought it would be interesting to ask folks from different walks of life and who have had longer and shorter walks (older and younger folks) how much they really noticed the head in a nice-looking kitchen with a lot of different aesthetics along the “old” and “new” lines. Just to see how much, unprompted, their eye was drawn to or affected by this homely head.Now that you know the nature of the issue, if you still have interest, you can let me know what you think of the head, knowing that was the “target” aesthetic question.Thanks much – PeterAnd now for the results:I got 12 responses, with respondents varying in age from about 30 to 65. The sample size was just too small to claim any differences in response based on age or their area of expertise (which ranged from building professionals to a sculptor).Only 3 of 12 respondents mentioned anything about the interior minisplit head, and two of those three were more concerned with the “distracting” large open wall space just below the head.There were some repeated themes:The white wall (where the minisplit head is) needs to be a color other than white.A shallow bookcase or something else should “fill” the space below the head.Artwork could be used to “fill” the large blank space. (In fact, the owners do have a piece of art there, hung shortly after this photo was taken.)I like/don’t like the mix of color and age of the ceiling beams.I love the daylighting in this kitchen.The range hood is distracting and/or it is too high above the cooktop to work right. (There were way more mentions of the aesthetics of the range hood than of the minisplit head).Specific aesthetic responses were all over the map, from “one of the ceiling planks is a different shade than the others” to “the white duplex outlet on the left hand end of the island should not be white” to “I love that etching of the owl.”I like how the photo shows the minisplit head AND the wood stove, another neat juxtaposition of “old” and “new,” a neat theme of this kitchen overall.Of the 12 initial respondents, 10 followed up to say the hood is essentially unobtrusive, with about half knowing what it was from the start and half not.So, I think the aesthetics of new technology, even something as “bulky” and “homely” as an interior minisplit head, can be more about the aesthetic context than anything else. And we can get desensitized to the aesthetic impact of the conventional and sometimes a bit hypersensitive to the new.PS – On the difficulty of cleaning/replacing the minisplit interior head filters: You pop open the front grille and the filters are right there to slide in and out with ease.
I started to learn to drive only three years ago, and — inevitably — failed my first test. Naturally, I was disappointed. But then it occurred to me that I could avoid the whole issue, if only I could get my hands on a driverless car. And this triggered the research question: what would the overall impact on travel demand, energy use, and carbon emissions be if driverless cars were readily available to the likes of you and me?I joined two like-minded academics in the U.S. — Don MacKenzie and Paul Leiby — to research how the automation of road transport might affect energy use, and to quantify the potential range of these impacts.We found that a widespread adoption of self-driving vehicles could indeed help to reduce energy consumption in a number of ways. For example, on motorways, automated vehicles can interact with each other and drive very closely as a “platoon.” This can reduce the total energy consumption of road transport by 4% to 25%, because vehicles which follow closely behind each other face less air resistance. RELATED ARTICLES What’s more, when vehicles can interact with each other and road infrastructure — such as traffic control systems — this will smooth out the traffic flow. The result will be less congestion and a reduction in energy use of up to 4%. On top of this, automated “ecodriving” — a driving style which controls speed and acceleration for more efficient fuel use — can reduce energy use by up to 20%.When you are riding in your self-driving car, obviously you won’t be at the controls, so you will no longer be able to enjoy the rapid acceleration of your driving days — so perhaps the desire for more powerful engines could diminish. And given that vehicle safety is expected to improve dramatically in self-driving cars, some of the heavy safety features could be removed, making cars lighter. Each of these changes could reduce energy use by up to 23%. Zia Wadud is an associate professor in transport and energy at the University of Leeds. This post originally appeared at The Conversation. Sharing is caringBut it’s not all bad news: self-driving cars could encourage a move away from current car-owning culture to a car-sharing or on-demand culture. This opens up a few different possibilities. For one thing, by making the per-mile costs more visible to the user, car sharing or automated taxis could reduce travel demand from individuals. Yet these shared automated cars may still travel empty for some parts of their trips, so this option could lead a reduction of energy use between 0% to 20%.But even greater energy savings are possible if the size of the self-driven shared car is matched to the trip type: for example, if a one-person commute trip is undertaken by a compact car, while for a family leisure trip a medium-sized sedan is used. This approach could reduce energy demand by 21% to 45%.One thing we haven’t touched in great detail is the potential for self-driving cars to encourage a switch to alternate fuels such as electricity and reduce carbon emissions. Imagine the car dropping you off at your destination and finding a charging point to recharge itself.So, automation does have the potential to reduce energy use for road transport. But this is not a direct result of automation per se; rather, it is due to how automation changes vehicle design, operations, and ownership culture. It’s also interesting that some of the energy-saving benefits of self-driving cars are possible at a lower level of automation, through increased interaction between vehicles and infrastructure.It is clear that the benefits of self-driving cars will depend on how we use them. The widespread adoption of automated vehicles could well have some unexpected effects, so it’s vital that we find and implement ways to realize the full energy-saving and carbon-reducing potential of self-driving cars. Until then, we’d better keep practicing our driving. The bigger pictureSo far, so good — all of these mechanisms improve the efficiency with which a car travels. But, as a society, our interest lies in reducing total energy use, or total carbon emissions — and energy efficiency forms only one half of this picture. Our total carbon emissions also depend on the demand for travel. So, while improving the energy efficiency of cars by automating the driving process will reduce the carbon emissions of individual vehicles, the overall impact of this change will depend on how many people use them.For instance, consider what would happen if large numbers of people switched to self-driving cars from traveling by train. We generally prefer the privacy and convenience of traveling by car, but using public transport means we can concentrate on other stuff — such as reading a book or getting some work done. A self-driving car offers all of these benefits. As a result, we found that driverless cars could prove so attractive that they increase car travel by up to 60% in the US.As you can see in the graphic below, the features of driverless cars may have a range of impacts on energy consumption — both positive and negative.Changes in energy consumption due to various mechanisms facilitated by automation. (Author provided)Self-driving cars could also encourage a completely new group of people to own vehicles — for example, the elderly, the disabled, and possibly those too young to drive themselves. This would increase the welfare of that demographic by giving them greater mobility. Yet travel demand, energy use and carbon emissions would all rise: our estimate for the U.S. is an increase between 2% and 10%.

Shikhar Dhawan had a stellar beginning to his Test career five years back and still boasts of a great record in home conditions but inconsistency with the bat in overseas conditions and his poor technique against swing bowlers led to his ousted from the Test squad earlier this month.But he isn’t the kind of player who goes into a shell when faced with challenges and wants to bounce back strong whenever he gets the opportunity.The recent T20I series against Australia saw the Delhi batsman amass 117 runs in two matches and was adjudged Player of the Series for his exploits as India shared the trophy with the hosts.Virat Kohli’s team will now face Australia in a four-match series from December 6, which will give Dhawan ample time to prepare for the ODIs which follows after the Tests from January 12.Looking back at his Test omission, Dhawan says he has moved on from the episode and is already looking forward to put his best foot forward in the 50-over format early next year.”Yes, I was a bit sad but I have moved on and I am in a good frame of mind. I am in a happy positive mood. I am enjoying my game. I have got a bit off time and I am going to enjoy my training and get myself fitter. I am happy and once I am happy things go well for me,” Dhawan told ESPN Cricinfo.The 32-year-old left-handed opener is also confident that India will do well in the Test series against Tim Paine’s Australia.advertisement”I think we have got a very good chance to win the series here. We have to play good complete cricket in all three departments whether it’s batting, bowling or fielding and also catching. We have to be consistent and then we will have a good chance of beating Australia,” said Dhawan.While the World Cup is still six months away, the focus will be on the process for the veteran of 115 ODIs.”I am going to give my best. I am a big believer in process and once I get it right, other things will follow on its own. Of course, we would like to bring the World Cup back home,” he exuded confidence.What makes him confident about his success in England is his past record in limited overs cricket.”I have done well in both Champions Trophies in England and with my experience, I hope to score a lot of runs in World Cup and give good starts and sail through so that we can get the Cup back,” Dhawan concluded.Also Read | Shikhar Dhawan breaks Virat Kohli’s record for most T20I runs in a yearAlso Read | Shikhar Dhawan breaks Virat Kohli’s record for most T20I runs in a yearAlso Read | Brisbane T20I: Shikhar Dhawan masterclass in vain as India lose thrillerAlso Read | Australia brace for a summer of battle against Virat Kohli
