Sprint's WiMax service to include local features

Sprint Nextel will put location-based services front and center on its Xohm WiMax service, offering a portal with widgets for local weather, traffic, events, reviews, and other information.

The carrier was set to announce on Thursday a partnership with uLocate Communications, along with Google, AccuWeather, Navteq, reviews site Yelp, and other content providers.

Sprint will discover subscribers' locations using information from its WiMax base stations. With uLocate's Where platform, it will present local content and services from the other partners, said Art Spivy, director of content and community services for Xohm. By the end of the year, Sprint also hopes to integrate uLocate's Buddy Beacon friend-finding service in the service.

Xohm will be a data-oriented service that users will access on devices sold by manufacturers at retail rather than by the carrier, as is common for cell phones. In addition, those devices won't have a standard "deck" or lineup of services constantly presented by Sprint. Client devices are expected to start with laptop cards and eventually include MIDs (mobile Internet devices), personal entertainment devices and other platforms. The service is set to launch in September in Baltimore, with more markets added in the coming months.

The location-based content will be presented on a Xohm Web portal and will change as a subscriber moves from one place to another. Subscribers will also be able to personalize the portal to offer information on the kinds of things they want. But they won't be forced to use that portal as a home page.

"We're not trying to replace AOL's or Yahoo's portal," Spivy said. "We're really trying to be a great start experience for your mobile session."

The content partners' information will be presented through widgets on the portal page. Other initial partners are set to include events and tickets company Eventful and localized news provider Topix. Sprint later plans to open up the portal to many more partners through a developer program. Policies for the privacy of user data will be included in that partner program, he said.

Sprint's move is part of an overall trend away from tight service-provider control of mobile content, according to analyst Greg Sterling of Sterling Market Research. Using the location data it gathers will help to draw subscriber's to Xohm's own portal on devices that could easily be used simply for Web access, but in the wake of the iPhone's personalized home screen, Sprint is not alone, he said.

"Everything, generally speaking, is moving toward greater openness and customization," Sterling said.

Palm Jumeirah to implement UAE's first vacuum sewerage system

Original Article

Dubai: Nakheel, a Dubai World company and one of the world's top real estate developers, announced on Thursday details of Palm Jumeirah's state-of-the-art vacuum sewerage system, which is the first system of its kind in the UAE and the largest of its kind anywhere in the world.

Nakheel said the vacuum sewerage system will play a key role in helping meet its sustainability objectives for the Palm Jumeirah.

Corodex Electromechanic, a part of Concorde-Corodex Group, has developed the system, which is one of the world's suppliers of water supply engineering and wastewater treatment systems.

The advanced vacuum sewerage system at Palm Jumeirah serves 2,000 villas through 900 collection chambers, 40 kilometres of pipeline and the world's largest vacuum station. The vacuum system delivers wastewater to a membrane bio-reactor MBR system sewerage treatment plant (STP) located on the Trunk of Palm Jumeirah.

In line with the Blue Communities ethos of minimising the environmental impact of Nakheel's developments, the state-of-the-art system has been designed so that there is absolutely no emission of treated effluent into the sea. Instead, the treated, safe wastewater is reused to irrigate landscaping on Palm Jumeirah, which reduces the demand for desalinated water and helps protect this vital resource.

The system's design offers a number of other environmental benefits, from low-cost and low-impact construction, to the ability to cross water protection areas because leaks cannot occur. This means that, unlike traditional treatment processes and pipe networks, the vacuum system is completely odourless. As the pipe network is all underground, it is also unobtrusive, providing an ideal solution in an urban environment.

Sony to launch world's slimmest 40-inch LCD TV

OKYO - Sony Corp. said Thursday it will launch the world's thinnest and lightest 40-inch liquid crystal display (LCD) television, seeking to trump its rivals ahead of the key year-end shopping season.

The new ZX1 model, part of the firm's popular Bravia series, is just 9.9 millimetres (0.39 inches) thick at its slimmest section

Weighing 12.2 kilograms (26.9 pounds), it can be hung on a wall like a framed painting.

Equipped with a fast wireless connection, the screen display is separated from the tuner so it does not need signal cables.

The ZX1 series will be put on the market on November 10 with an estimated price tag of about 490,000 yen (4,500 dollars) in Japan.

Sony also announced three other new series of Bravia LCD televisions with screen sizes ranging from 40 to 55 inches. They will be sold in Japan from October 10.

Of them, the W1 series can project images moving four times faster than conventional models.

"We will expand our line-up of products with displays at 40 inches or larger as demand for them is on the rise," Takao Yoshikawa, Sony's director of flat TV business division, said.

Sony is "on its track" to meet its global TV sales target of 17 million units for the year to March 2009, he said.

Who’ll Win ‘Smart Grid’ Gold? Keep an Eye on Duke, Ambient, eMeter, EnerNOC, GridPoint, Trilliant & More

Original Article - EnergyTechStocks.com

Posted: August 27, 2008

Much has been written about the critical need to fix the faltering power grid, the rapid development of plug-in electric hybrid vehicles in the face of record pump prices, and corporations’ strong interest in energy efficiency to combat rising power costs. Not much has been written – yet – about what has to first be in place for all this to happen, namely: the technology for making a power grid “smart.”

The “smart” electrical power grid, parts of which are now under development by many different companies, will act like a cellular telephone network. Its computer-controlled technology will permit two-way communication between power plants and literally everything that runs on electricity. The technology will include power management chips embedded in every TV and toaster, plus sophisticated monitoring systems all along the distribution chain – in the plant, on the lines, and in your home and office, where advanced programmable thermostats will, for the first time, put at your fingertips the power to save money and limit your greenhouse gas emissions.

The smart grid will make it possible for businesses to instantly adjust the energy usage of dozens of large factories, retail establishments, and other power users at the same time. It will make it possible to plug in millions of electrically-powered cars and trucks at any given time without overloading the system. Indeed, it is expected that the electricity stored in plug-in cars’ batteries will become a vital power source in its own right since utilities will be able on command to pull that electricity out of all those batteries when extra power is needed quickly to avoid a blackout. That, plus the inherent ability of a smart grid to diagnose and repair itself before trouble develops, will go a long way toward fixing what’s wrong with today’s faltering grid.

A lot of companies are racing for smart-grid gold, and given that it’s been estimated that the smart grid may generate some $45 billion in revenue for its developers, there should be multiple gold medals handed out. So here’s a list of companies that appear to be in line to make their investors happy along with some reasons why. The list is by no means exhaustive; it’s intended only to give investors a sense of the many different money-making opportunities that exist with smart grid development. (Look for frequent updates.)

Duke Energy and XCel Energy are the two investor-owned U.S. electric utilities trailblazing smart grid applications on their systems. Both have regulators pushing them to go green so their interest is unlikely to wane. Both may wind up acquiring cutting-edge technology firms, which could result in significant licensing fees as the rest of the notoriously slow U.S. electric utility industry plays catch-up. (For more on Duke see The Electric Revolution (Part 3 of 4) – Duke Energy’s David Mohler: ‘Utility of the Future’ Arrives Next Year.)

EnerNOC Inc. appears to be on a roll as a provider of demand response (DR) systems that rely on smart-grid-like computer controls to trim customer demand on the command of a utility when the grid is in danger of overloading. Increasingly, EnerNOC is using its technology to do forensic analyses of companies’ power usage, which will be another function of smart grid technology. (For more on EnerNOC see EnerNOC CEO Healy Sees ‘Demand Response’ 10% of Power Generation Mix In Less Than 5 Years.)

Ambient Corp. is a company developing technology intended to give the smart grid two-way communication capability. Utilities are going to need to turn their “dumb” electrical wires into “smart” wires capable of Internet-based communication in order to execute all sorts of demands to optimize and minimize power usage.

Echelon Corp. and privately-held eMeter are developing advanced meters that will serve as collection points for information passed along wirelessly and by Internet-capable power lines. Advanced meters will be key to utilities providing innovative pricing plans that encourage power users to switch their consumption to times of day when demand is low – and so is the price. (For more on Echelon see The Home-Improvers: 5 That Could Do Well Improving Home Energy Efficiency — #1 Echelon.)

GridPoint Inc., which is also privately held, is developing back-up power systems for when the power is interrupted. These smart battery-based systems will automatically spring into action, helping manufacturers and others avoid power breaks which, even if they last only fractions of a second, can force a company to lose hours because it needs to reprogram its computers. (For more on GridPoint see Follow the Money: 5 Firms Grabbing Big Bucks That Belong on Investors’ Radar Screens: #5 GridPoint.)

Meanwhile, Freescale Semiconductor, Texas Instruments, Atmel Corp. and Ember Networks, the first three publicly held, are all involved in developing the power management chips that will go into the many millions of TVs, toasters and other appliances. Privately-held Trilliant Inc. wants to be the main company that puts power management chips onto circuit boards, creating a wireless mesh network for communication within a home or office as well as back to utilities.

Moving Security to the Cloud

Original Article

Combining scanning approaches could keep PCs safe from viruses.

Most people know better than to connect a computer to the Internet without first installing up-to-date antivirus software. But even the best software protection won't catch every new virus, and performing a thorough system scan can require plenty of processor power, slowing some computers to a crawl.

New research from the University of Michigan suggests that computers could be better protected from viruses without sacrificing performance if antivirus software were moved from the PC to "the cloud"--a collection of servers that work seamlessly as one powerful machine. Using this approach, researchers found that they could detect 35 percent more recent viruses than a single antivirus program (88 percent compared with 73 percent). Moreover, using the distributed software, called Cloud AV, they caught 98 percent of all malicious software, compared with 83 percent, on average, for a single antivirus solution.

"We were concerned about the fact that the detection coverage of antivirus software from most popular vendors was poor," says Farnam Jahanian, a professor of computer science and engineering at the University of Michigan. If a single PC could use a combination of antivirus services, Jahanian says, security could be improved, but this would be a huge drain on resources. "We can run multiple programs, in parallel, and by doing that we're moving the antivirus functionality into the network cloud and addressing the limitations of antivirus services that reside only on the personal computer," he adds.

Jahanian and his colleague Jon Oberheide started by scanning 10,000 malware samples collected over the past year using several different antivirus programs. Oberheide notes that each program had its own strengths and weaknesses and that malware missed by one program would often be caught by another. So, to make the most of each program, the researchers installed 12 different antivirus programs on servers running the University of Michigan's College of Engineering network. Volunteers also installed a small piece of software on their computer to detect the arrival of any new file, whether that was an e-mail attachment or a downloaded program.

New files are converted into a unique string of characters, or a "hash," of less than 100 bytes, which is sent to Cloud AV for analysis. If a file can't be identified, it is sent in its entirety for full analysis. Other files can be identified as either safe or a threat based on hashes stored in a database maintained by Cloud AV.



In addition to employing several antivirus services in parallel, Cloud AV makes use of information received from multiple users. Whereas ordinary antivirus software simply looks at the files and activity on one machine, Cloud AV can compare the files on thousands of machines. Catching a virus on one system automatically protects any other machine connected to Cloud AV from the same threat.

"We're able to do something that's impossible to do when you run antivirus software only on your desktop," says Jahanian. This network effect also helps keep bandwidth requirements low because once Cloud AV has analyzed one particular spreadsheet, it doesn't need to scan the entire file again when it arrives on someone else's computer.

"Sometimes the best ideas are simple ideas," says Wenke Lee, a professor at the College of Computing at the Georgia Institute of Technology. Lee adds that the research provides a realistic scenario. "A lot of papers are written using synthetic data or small-scale network traffic, but this work is an actual demonstration of the system's capabilities," he says.

Although other companies offer server-side antivirus services, these only use one detection system and can only analyze files being sent across the network. Google provides a similar scanning service, called Google Message Security, for companies that use its Web-based applications. "We very much agree that putting these types of solutions in the cloud makes a lot of sense, given the way that they evolve, morph, and mutate," says Adam Swindler, head of Google applications security.

But it's still unclear whether a network-based solution like Cloud AV could be deployed very widely. "If you start putting billions of messages through this process, some questions of scalability arise," says Swindler.

Another issue is privacy, since such a system logs every file that comes in and out of a computer. This is one more question that has yet to be answered. "When you talk about cloud-computer and data security, you've got to be sure, based on the terms of service, that the data is going to be provided to the customer [when he or she wants it] and made secure," says Swindler.

Dh50 billion Culture Village inches closer to completion

: Dubai Properties, master real estate developer and a subsidiary of Dubai Properties Group (DPG), a member of Dubai Holding, announced that the Dh50 billion Culture Village project has crossed key construction milestones, including the completion of 90 per cent of the Dh1 billion infrastructure works.

Dubai Properties recently premiered Culture Village's residential component at Harrods in London to an excellent reception from investors.


Canal works within the 40 million sq. ft. Culture Village site, situated next to the Garhoud Bridge along the Dubai Creek, is 95 per cent complete. While the residential, commercial and retail districts within the project are being developed by 15 private developers, building works for these districts are being simultaneously undertaken.
