Traffic Claming

Traffic calming is a set of strategies used by urban planners and traffic engineers which aims to slow down traffic and get better safety for pedestrians and bicyclists, although some of these features can also be hazardous to cyclists. It is now comparatively common in Europe, especially Northern Europe; less so in North America. Traffic calming has conventionally been justified on the grounds of pedestrian safety and reduction of noise and local air pollution which are side effects of the traffic. However, it has become more and more apparent that streets have many social and recreational functions which are severely impaired by fast car traffic. For much of the twentieth century, streets were designed by engineers who were charged only with ensuring traffic flow and not with development other functions of streets. The rationale for traffic reassuring is now broadening to include designing for these functions.

Electromagnetic hypersensitivity syndrome

Some users of mobile handsets have reported feeling several unspecific symptoms during and after its use, such as flaming and tingling feelings in the skin of the head and extremities, fatigue, sleep disturbances, dizziness, loss of mental attention, reaction times and memory retentiveness, headaches, malaise, tachycardia and disturbances of the digestive system. Some researchers, implying a causal relationship, have named this syndrome as a new diagnostic entity, EHS or ES. The World Health Organization prefers to name it “idiopathic environmental intolerance", in order to avoid the insinuation of causation.

Management information system


Management Information Systems (MIS) is a general name for the educational discipline casing the application of people, technologies, and procedures —together called information systems — to solve business problems. MIS are distinctive from normal information systems in that they are used to evaluate other information systems applied in operational activities in the organization. Rationally, the term is commonly used to refer to the group of information management methods attached to the automation or support of human decision making, e.g. Decision Support Systems, Expert systems, and Executive information system

CPU Socket

The term CPU socket (or CPU slot) is commonly used to describe the connector linking the motherboard to the CPU in certain types of desktop and server computers, particularly those compatible with the Intel X86 Architecture.

Most CPU sockets and processors in use today are built around the pin grid array (PGA) architecture, in which the pins on the base of the processor are inserted into the socket. To aid installation, zero insertion force (ZIF) sockets are usually used, allowing the processor to be inserted without any confrontation, while gripping the pins firmly once the processor is in place to ensure a reliable contact. In contrast to CPU sockets, slot-based processors and CPUs use a single-edged connection rather than a socket, and slot into the motherboard on their side. Slot architectures are not often used today.
