A Call Center (American English) is a centralized office of a company that answers incoming telephone calls from customers (often for the purposes of product support), or that makes outgoing telephone calls to customers (e.g. telemarketing and debt collection). Such an office may also respond to letters, faxes, e-mails and similar written correspondence. However, the term contact centre is often applied when such multiple functions are blended in one office A call centre is generally set up as a large room, with work stations that include a computer...

Data Mining, also known as knowledge-discovery in databases (KDD), is the practice of automatically searching large stores of data for patterns. To do this, data mining uses computational techniques from statistics, machine learning and pattern recognition.
Data mining has been defined as "The nontrivial extraction of implicit, previously unknown, and potentially useful information from data" 1 and "The science of extracting useful information from large data sets or databases" 2. Although it is usually...

A White Paper can be an authoritative report on a major issue, as by a team of experts; a government report outlining policy; or a short treatise whose purpose is to educate industry customers. It is called white paper because it was originally bound in white.
Over time, the term white paper has also come to refer to documents that argue non-governmental positions as well. For example, many white papers today espouse the benefits of particular technologies and products. These types of white papers are often marketing...

Recent Technology News: NASA's Stardust mission successfully ends

Stardust is an American interplanetary spacecraft, whose primary purpose is to investigate the makeup of the comet Wild 2 and its coma. It was launched on February 7, 1999 by NASA, traveled nearly 3 billion miles (5·109 km), and returned to Earth on January 15, 2006 to release a sample material capsule. It is the first sample return mission to collect cosmic dust and return the sample to Earth.

After launch in 1999, the Stardust spacecraft traveled in an initial orbit beyond- but intersecting- Earth's orbit. The Delta II booster did not have enough energy to reach Wild 2 directly. The Stardust spacecraft then re-approached Earth in January 2001 for a gravity assist maneuver. The encounter with Earth enlarged the spacecraft's orbit to intersect that of Wild 2.

On the second orbit, Stardust flew by the comet Wild 2 on January 2, 2004. During the flyby it collected dust samples from the comet's coma and took detailed pictures of its icy nucleus. Additionally, the spacecraft accomplished several other goals. It passed within 3300 km of the asteroid 5535 Annefrank on November 2, 2002 and took several photographs. The aerogel collector also acquired interstellar dust. In March-May 2000 and July-December 2002, the spacecraft angled itself into a dust stream believed to originate outside the solar system. The reverse side of the aerogel collector then caught a sample of such particles.

On arrival, the capsule was traveling in a nearly flat trajectory, at 12.9 km/s (28,900 miles per hour), which is the fastest re-entry speed ever achieved by a man-made object. As a point of comparison, NASA's Utah ambassador stated it would be able to travel from Salt Lake City, Utah to New York City, New York in less than six minutes. A large fire ball and sonic boom were observed in western Utah and eastern Nevada.

The sample material capsule from Stardust returned to Earth at approximately 10:10 UTC on January 15, 2006 in Utah's Great Salt Lake desert, near the U.S. Army Dugway Proving Ground, to deliver the sample material. The landing coordinates were 40°21.9′N 113°31.25′W. Winds had blown the capsule a few miles off its ballistic trajectory, but it was within the target area.

The Stardust mother ship had been put into a "divert maneuver" to keep the hardware from hitting Earth. NASA is considering sending it to another comet or asteroid. Under twenty kilograms of fuel remain onboard after the maneuver. Individuals who wish to propose post-return uses for the spacecraft to NASA may submit a proposal for the use of the spacecraft in response to the current Discovery Announcement of Opportunity, a document released on January 3, 2006. On January 29, the craft was put in hibernation mode with only its solar panels and receiver still active. It may be reawakened for a future mission (one possibility: flying by the comet 9P/Tempel that was the target of the Deep Impact mission); for now, it's in a three-year heliocentric orbit that will return it to the Earth's vicinity on January 14, 2009.

Donald Brownlee, from the University of Washington, is the Principal Investigator for the Stardust mission.


Microsoft unveils the Ultra-Mobile PC, "Origami Project".

The Ultra-Mobile PC (abbreviated UMPC), previously known by its codename Project Origami, is a specification for a small form factor tablet PC. It was developed as a joint development exercise between Microsoft, Intel, and Samsung, among others. Current UMPCs feature the Windows XP Tablet PC Edition 2005 operating system and low-voltage Intel Pentium processors in the 1 GHz range.

Ultra-Mobile PCs have a 20 cm (7-inch) touch sensitive screen at a minimum resolution of 800 × 480. Windows XP Tablet PC Edition is used with slight tweaks to the interface to make it more suited for the small form factor. In addition, a software suite known as the Touch Pack Interface is included to make the interface more suitable for use of stylus as well as hand.

The Ultra-Mobile PC is just a platform for which manufacturers can design any model they want, provided they meet or exceed the baseline specifications laid down by Microsoft. When the UMPC was disclosed as CeBIT 2006, Samsung, ASUS and Founder had near-complete devices on display. Pricing is expected to be in the range of $599 to $999.

UMPCs will be able to run any software that has been written for the Windows XP platform, though the small form factor will mandate some changes to the interface. The standard Windows XP interface is the default, though a choice of having an interface more suited for the small form factor is available with the Touch Pack Interface. Due to the small size, UMPC do not feature a physical keyboard, but a virtual keyboard, known as DialKeys, is provided in the Touch Pack Interface. Also, since the device has standard USB 2.0 connectivity, external keyboards and mice can be attached.

UMPCs will include 1 GHz Intel Celeron M, Pentium M or VIA C7-M processors, with 256 MB RAM, and will include 30 GB to 60 GB harddisks, depending on the manufacturer. They could also feature GPS devices, webcams, fingerprint readers, TV tuners, or memory card readers. Bluetooth, Wi-Fi and Ethernet are all supported as well.

UMPCs have enough processing power to support audio, video, and gaming, in addition to having rich support for browsing the internet as well as for other communication and networking applications. Windows Media Player will be included, with minor tweaks to provide a better experience on the small screen. The devices will also feature DirectX 8–class graphics, and all applications available for standard Tablet PCs are expected to be compatible.

In future, the prices of UMPCs are expected to come down to the $500 range, and battery life is expected to increase from the present two and a half hours to eight hours. UMPCs will be upgraded to include Windows Vista later this year.
