Satellite television is a service that delivers programming to viewers by relaying it from communications satellite orbiting the Earth directly viewer's location. The signals are received via an outdoor parabolic antenna commonly referred as dish and low-noise block down converter. A receiver then decodes desired programme for viewing on set. Receivers can be external set-top boxes, or built-in...

This paper provides an internal look at the thoughts and activities of American interactive television (iTV) executives and producers circa 2002. Based on in-depth interviews it first suggests a comprehensive definition of the US iTV landscape. Then, by providing a case study of three pioneering iTV productions, it examines the organizational aspects of producing interactive television through ...

Sentiment analysis of citations in scientific papers and articles is a new and interesting problem which can open up many exciting new applications in bibliographic search and bibliometrics. Current work on citation sentiment detection focuses on only the citation sentence. In this paper, we address the problem of context-enhanced citation sentiment detection. We present a new citation sentimen...

The standard definition of causal Bayesian networks (CBNs) invokes a global condition according to which the distribution resulting from any intervention can be decomposed into a truncated product dictated by its respective mutilated subgraph. We analyze alternative formulations which emphasizes local aspects of the causal process and can serve therefore as more meaningful criteria for coherenc...

For the standard definition video, the inherent delay produced by the existing coding standards is above 260ms. The delay is too big to apply in real-time video processing system. In order to reduce codec system delay, this paper gives a low delay coding structure. Firstly, the input video is divided into a number of slices for reducing the acquisition delay, and then the slice is coded as a ba...

The concept of conditional probability has been employed for hundreds of years. Thomas Bayes used the expression "the probability that [B] on the supposition that [A]" in the statement of a basic law (1763, p. 378). Frank Ramsey, developing the application of probability to uncertain epistemic attitudes, the "logic of partial belief (1926, p. 166), wrote of your "degree of belief in [B] given [...

This paper, derives sufficient conditions for the existence of chaotic attractors in a general n-D piecewise linear discrete map, along the exact determination of its dynamics using the standard definition of the largest Lyapunov exponent. c © Electronic Journal of Theoretical Physics.

The corner stone of the interoperability of eLearning systems is the standard definition of learning objects. Nevertheless, for some domains this standard is insufficient to fully describe all the assets, especially when they are used as input for other eLearning services. On the other hand, a standard definition of learning objects in not enough to ensure interoperability among eLearning syste...

Starting from a non-standard definition, the descent algebra of the symmetric group is investigated. Homomorphisms into the tensor product of smaller descent algebras are defined. They are used to construct the irreducible representations and to obtain the nilpotency index of the radical.

While the definition of clinical research is not easy to find today, how we define this term is critical in putting this crisis in clinical research into perspective. Therefore, we need to establish a standard definition of clinical research. Also, we need to identify why clinical research is so important, particularly with major public health problems such as obesity in America today. Obesity ...
