Abstract:
Through an examination of the emerging domain of cognitive systems, with a focus on attention-centric cognitive systems used for notification, this document explores the human-computer interaction challenges that must be addressed for successful interface design. This document asserts that with compatible tools and methods, user notification requirements and interface usability can be abstracted, expressed, and compared with critical parameter ratings; that is, even novice designers can assess attention cost factors to deter ....etc

Direct to home (DTH) television is a wireless system for delivering television programs directly to the viewer's house. In DTH television, the broadcast signals are transmitted from satellites orbiting the Earth to the viewer's house. Each satellite is located approximately 35,700 km above the Earth in geosynchronous orbit. These satellites receive the signals from the broadcast stations located on Earth and rebroadcast them to the Earth.

The viewer's dish picks up the signal from the satellite and passes it on to the receiver l ....etc

Gasoline direct injection or GDI is a variant of fuel injection employed in modern four stroke petrol engines. The gasoline or biobutanol is injected right into the combustion chamber of each cylinder, as opposed to conventional multi point fuel injection that happens in the intake manifold.

GDI enables stratified charge (ultra lean burn) combustion for improved fuel efficiency and emission levels at low load. Further improving efficiency and high-load output-power, the engine power is governed by modulating fuel injection, like a diesel eng ....etc

The world is surely and steadily moving towards the newer generation of direction injection diesels, be it unit injected or common-railed. Mercedes Benz had already introduced the common rail engine in India a few years back but then they are the technology leaders worldwide and augur no comparisons. so. it was a matter of time before one of the other car manufacturers in India took up the challenge and introduced the engine in a car that could be available to a much larger segment of the car-buying populace.

As it has done on a number of ....etc

Human“computer interaction (HCI) is the study of interaction between people (users) and computers. It is often regarded as the intersection of computer science, behavioral sciences, design and several other fields of study. Interaction between users and computers occurs at the user interface (or simply interface), which includes both software and hardware, for example, general-purpose computer peripherals and large-scale mechanical systems, such as aircraft and power plants. The Association for Computing Machinery defines human-computer i ....etc

The Idea Of Direct Memory Access
By providing circuitry to generate addresses and memory control signals independently of the processor we see that it is possible to improve performance considerably. All that is necessary is to provide a signal to tell the processor to remove itself from the bus so there is no contention on the memory control, address, or data lines.

This is the entire concept behind direct memory access (DMA). To complete our picture, it is important to note that there are actually several ways that DMA can be ....etc

ABSTRACT
The Human-Computer Interface is a multidisciplinary field concerned with the design and evaluation of interacting computer systems from the user perspective. It deals with the way that computers and their users communicate. It pertains to the performance of tasks by humans and machines, the structure of human-machine communication, the engineering aspects of designing, building and specifying interfaces so that computers are easy to use and do what people want them to do. HCI requires the understanding of the capabi ....etc

The need for high energy density, lightweight power sources for demanding portable applications gives incentive to the search for novel fuel cell concepts and approaches that reduce size, weight, and system complexity. Such power sources would find applications in variety of portable medical devices, computer hardware, and military equipment. This talk addresses a direct methanol fuel cell (DMFC) system approach wherein the fuel (methanol) and air are mixed and fed simultaneously to anodes and cathodes of the fuel cell stack. This overall appro ....etc
