What can be inferred, without assuming the Independence axiom, about an agent’s preferences over many-good lotteries from knowledge that the agent is income risk averse? We show that income risk aversion corresponds to an intuitive substitution property of the many-good lottery preferences that is, itself, equivalent to a standard definition of many-good risk aversion. We apply our approach to ...

The standard definition of limz→∞ F (z) = ∞ is an ∀∃∀ sentence. Mostowski showed that in the standard model of arithmetic, these quantifiers cannot be eliminated. But Abraham Robinson showed that in the nonstandard setting, this limit property for a standard function F is equivalent to the one quantifier statement that F (z) is infinite for all infinite z. In general, the number of quantifier b...

In the United States, the Federal Communications Commission (FCC) began a process six years ago to develop a terrestrial high definition television (HDTV) broadcasting standard. Early in 1993 a comprehensive report was released by the FCC's Advisory Committee on Advanced Television Service comparing five proposed systems that had undergone extensive testing. Although the report did not pick a "...

the aim of this study was to compare the time spent watching television, the expected moral values ​​transmitted via television, the features of life and sport patterns and the moral properties of selected patterns between high school male and female students. in this survey, population consisted of high school male and female students in islamabad gharb city in 2012. the sample was 382 subject...

We propose a non−linear image enhancement method based on Gabor filters, which allows selective enhancement based on the contrast sensitivity function of the human visual system. We also propose an evaluation method for measuring the performance of the algorithm and for comparing it with existing approaches. The selective enhancement of the proposed approach is especially suitable for digital t...

Why High Definition (HD) is Important Why are advances in video communications technology important? Such innovations matter because the productive value of interactive video is inextricably bound to the technology itself. After all, no one would watch television if it was difficult to turn on and had a low quality picture. Similarly, the reluctance to actively use video communications is linke...

This paper presents a hardware prototype of the H.264 transformation. The proposed architecture uses only add and shift operations to reduce the computational requirements for the 4 4 transform. The architecture is developed to be used in high-resolution applications such as High Definition Television (HDTV) and Digital Cinema. The developed architecture is prototyped and simulated using ModelS...

Interlaced scanning has been used for a long time in analog SDTV systems. With the increasing demand for high resolution video services, a number of countries have started to offer high-definition television broadcasting services. Although recent displays such as LCD and PDP are more suitable for the progressive scan format, the interlaced scan format still constitute a key part of the HDTV sta...

While traditional technology acceptance models concentrate on relationships between usefulness and acceptance, they leave unresolved the questions about why a certain technology is found useful, in which contexts, and by whom. This paper presents an empirical study of some of the factors behind perceived usefulness of HDTV in the Netherlands, where the adoption process has just begun. Results s...
