Collision article - Collision Physics Billiards Traffic Others Telecommunications physics - What-Means.com Because the collisions between billiard balls are almost perfectly elastic, and the balls roll on a low-friction surface, their predictable behaviour is often used to illustrate Newton's laws of motion. Collisions can be elastic, meaning they conserve energy and momentum, inelastic, meaning they conserve momentum, or Totally inelastic, meaning they conserve momentum and the two objects stick together. In traffic such a collision can be between two vehicles, a vehicle and a person, a vehicle and an object, two persons or a person and an object (and more if an animal is involved). www.what-means.com /encyclopedia/Collision

afrika.no - Kenya: May clash with donors Telkom Kenya is being looked at afresh in view of the recent growth in the telecommunications sector globally just a year after talks for the sale of a 49 per cent stake in the parastatal collapsed, with the preferred bidder Mount Kenya Consortium offering $320 million. The Kenya government appears headed for a collision course with lenders over a plan to shut out strategic investors from acquiring stakes in the remaining parastatals slated for privatisation, in a bid to make them more relevant to economic development needs. It is thought that the Kenya Commercial Bank, in which the government still holds a 35 per cent interest, will be refocused to offer more credit to the agricultural sector. www.afrika.no /Detailed/3473.html   (11979 words)

Data retention news: EU Council, Germany, Spain EDRI The Council of European Ministers of Justice and Home Affairs (JHA council) seems set for a frontal collision with the European Commission with the proposal for a framework decision on mandatory data retention. The German DPAs note that the proposal is not only unconstitutional in Germany, but also in violation of the draft European Constitution in which privacy and telecommunications secrecy are enshrined as pillars of a free democratic society. Spain was the first country in the EU to adopt general framework legislation demanding data retention in the summer of 2002, immediately after the EU privacy directive was adopted which allowed for national legislation on data retention. www.edri.org /edrigram/number3.6/retention   (11979 words)

Telematics - Wikipedia, the free encyclopedia Vehicle telematics systems may be used for a number of purposes, including collecting road tolls, managing road usage (the United States Department of Transportation intelligent transportation system), tracking fleet vehicle locations, recovering stolen vehicles, providing automatic collision notification, and providing location-driven driver information services. The [integrated] use of telecommunications and informatics, also known as ICT (Information and Communications Technology). Vehicle telematics systems are also increasingly being used to provide remote diagnostics; a vehicle's in-built systems will identify a mechanical or electronic problem, and the telematics package will automatically make this information known to the vehicle manufacturer and service organisation. en.wikipedia.org /wiki/Telematics   (11979 words)

Speed demon gets hooked on silicon: Science News Online, Sept. 15, 2001 The new process may also make more affordable such technologies as collision-avoidance systems for vehicles and fiber-optic telecommunications to homes. Wafers of gallium arsenide and other semiconductors that can transmit electrons at high speeds and efficiently emit or detect light are costly and fragile. Previous efforts to graft such compounds onto a cheap, flexible silicon base failed because their crystalline structures don't align with that of silicon. www.sciencenews.org /20010915/fob4.asp   (303 words)

Strategic Communications Choices The idea behind Fast Ethernet is to keep the sharing mechanism used by conventional Ethernet, the Carrier Sense Multiple Access with Collision Detection (CSMA-CD), but to adapt the physical characteristics to enable it to operate 10 times faster (100Mbps). Computer and telecommunications vendors have done an excellent job of promoting their leading-edge technologies at network shows across the globe. Unfortunately, this information doesn't help the corporate manager faced with immediate strategic choices. www.windowsitpro.com /Articles/Index.cfm?ArticleID=2348   (303 words)

EE Times -Researchers lay plans to build 500-GHz transistors The HEMT, operating at 386 to 398 GHz, opens doors to developing, by mid-decade, such products as automotive collision-avoidance radars at 76- to 77-GHz frequencies, ITS trunk communications, and 100-Mbit/second home LANs at 60 GHz, said Fujitsu Labs Fellow Takashi Mimura. To do that, the group — which is backed by Japan's Ministry of Public Management, Home Affairs, Posts and Telecommunications &; will have to shorten the HEMT's gate from its present 25-nm width down to 10 nm, he said. Ultrahigh-frequency HEMTs will deliver at least double the gain of present-generation gallium arsenide devices, said Shinohara. www.eetimes.com /story/OEG20010419S0057   (303 words)

ERAST Commercialization Site One is the system for avoiding collision with other aircraft, and the other is the system for remotely controlling the aircraft during "over the horizon," flights, meaning beyond the ground pilot's line of site. Under the aegis of a government-industry partnership, ERAST is providing a diverse family of remotely piloted aircraft and sensors for environmental science, telecommunications, remote sensing, and other applications. This first test of the "virtual scientist" proved that meaningful science can be conducted with a remotely piloted vehicle and a team of scientists located 3000 miles from the point of data collection. www.erast.com /ehtml/alliance.html   (303 words)

SPACE.com -- Astronotes: The inside scoop on the Universe at large. In the summer of 2001, French scientists reported that Etna appeared to be undergoing a gradual shift from being a "hot spot" volcano, in which magma wells up from within the Earth, to an "island arc" volcano, in which magma is produced from the collision of tectonic plates. Once in Earth orbit, the APSTAR VI can provide broadcasting and telecommunications services for regions including China, Southeast Asia, Australia and Hawaii of the United States, the state-controlled news outlet, China Today, has reported. Chinese satellite officials have announced in Beijing that APSTAR VI will become that country's first foreign-made spacecraft designed to thwart malicious interruptions, that is, airwave hi-jacking. www.space.com /news/astronotes_oct28-nov3.html   (303 words)

International Federation of Journalists Press Release, 5/27/02 The IFJ is calling on MEPs to reject amendments to the 1997 European Directive on the Protection of Telecommunications Data and Information to allow EU states to pass laws to keep data about people's electronic communications for access by police, customs, immigration and intelligence services. Because the measure is subject to the co-decision procedure, whereby the Council and the European Parliament have to agree the final text, the two bodies are potentially on a collision course. The International Federation of Journalists and its European regional group, the European Federation of Journalists today called on the European Parliament to block attempts this week to allow member states to pass laws that will give the authorities regular access to people's telephone and Internet communications. www.gilc.org /ifj_release.html   (452 words)
