T HE discrete memoryless broadcast channel (%P(YJlX), 94 x 3) consists of three finite sets % ., 9, % and a probability transition matrixp(y,zjx). Let p,(ylx) andp,(zIx) be the two marginals of p(y,zlx), and let P, and P2 denote the discrete memoryless channels with probability transition matrices p&y Ix) and pz(zlx), respectively. Recall the following three relations between P, and P2. Definit...

This study aims at finding out if households or organizations are faster in their acceptance of a technological innovation. The object of this study is digital terrestrial television (DTT), specifically the implementation of DTT in Denmark. The theoretical framework is diffusion of innovation theory. Three surveys were carried out for both households and organizations. Based on the surveys, the...

As digital television matures, applications which utilize data embedded in the broadcast television signal are likely to be an important feature of the new medium. This paper explores some of the issues involved in the implementation of systems for the utilization of data which accompanies digital television's video and audio content. Chief among these issues are those which

This report is a literature survey that investigates the effect of feedback on the capacity region of multiple access channels (MAC) and broadcast channels (BC).

The key ideas in the theory of broadcast channels are illustrated by discussing some of the progress toward finding the capacity region. The capacity region is still unknown.

Background: The aims of the study are to determine the radioactivity concentrations of 226Ra, 238U, 232Th and 40K in vegetables of a recently found high background radiation area of south-eastern part of Bangladesh and to detect the radiological risks to human from intake of these vegetables. Materials and Method: 10 plant samples were collected randomly from different locations of the study ar...

The study examines the effect of several television ownership attributes on the fraction of prime-time broadcast television minutes devoted to different programming types, as well as the effect of these ownership attributes on prime-time broadcast advertising minutes and rates. Overall, the study considers an interesting question with appropriate data and methods and should ultimately prove use...

Natural radionuclides present in soil as well as certain anthropogenic radionuclides released to the environment are the major contributors to terrestrial outdoor exposures. In the assessment of human exposures from environmental radioactivity, besides the conventional method of soil and vegetation sampling combined with laboratory based analyses of environmental media, the other choice would b...
