There have been many theoretical and experimental investigations on polarization diversity reception characteristics at base stations. The diversity gain was evaluated based on the distribution of the instantaneous received power in these investigations. The mainstream mobile communication systems are shifting to standardized IMT-2000 systems and the W-CDMA system is one of them. The effect usi...

Purpose: In this article we illustrate the importance of understanding the risk profiles of new technologies, in addition to the changes in productivity, to be able to determine strategies for agricultural development. Design/methodology/approach: The analysis is based on data obtained from a 2002 survey of subsistence farmers in the Kilimanjaro region of Tanzania, and a Just and Pope (1978) fr...

BACKGROUND Due to the increasing health care costs, the issue of productivity in hospitals must be taken into great consideration in order to provide, preserve and promote public health services. Thus, increasing the level of productivity must become the main aim of any hospital. Objective of this study is to determine the total factor productivity and its components over the period under the s...

Object-oriented programming promises to increase programmer productivity through better reuse of existing code. However, reuse is not yet pervasive in today’s object-oriented programs. Why is this so? We argue that one reason is that current programming languages and environments assume that components are perfectly coordinated. Yet in a world where programs are mostly composed out of reusable ...

BACKGROUND Realising the economic potential of research institutions, including medical research institutes, represents a policy imperative for many Organisation for Economic Co-operation and Development nations. The assessment of research impact has consequently drawn increasing attention. Research impact assessment frameworks (RIAFs) provide a structure to assess research translation, but min...

Better programming productivity may be obtained by choosing suitable programming paradigms. For development of complex software systems, multiparadigm programming would usually be appropriate. However, its use may be hindered by a lack of languages and programming support tools. As this paper argues, multiparadigm programming may be supported by translators that convert programs written in one ...

background: universities play an important role in training people to meet the community demands for skilled manpower. furthermore, it is a fact known that universities do most of the research projects in iran and in most countries through out the world. it is, therefore, important to know about teaching and research productivity in universities and to determine this productivity. theoretically...
