To achieve a cost-effective network deployment, employing state-of-art technical advances provides a practical and effective way to enhance system performance and quality of service provisioning. Cooperative transmission has been recognized as one of the most effective paradigms to achieve higher system performance in terms of lower bit-error rate, higher throughput, larger coverage, more effic...

farmers need up to date information on efficient use and management of labour for agricultural production. yet, they lack adequate and needed information. hence, this study was undertaken to explore the sources and use of labour information by farmers in southwestern nigeria. multi-stage sampling procedure was used to select respondents for the study. primary data were collected to elicit infor...

A research can also reveal the cooperative effectiveness of agencies such as evaluation will lead to discover the weakness and strengths for further improvement of this program. The present study was designed in 2009 especially to see the effectiveness of the working of agricultural extension staff as perceived by farmers in district Okara-Pakistan. The data were collected with the help of a sp...

For many individuals, work is the center of life. As much as half an individual's waking hours may be spent at work or commuting to or from work. However, recent evidence indicates that many people are dissatisfied with their jobs or alienated from work in general--with unfortunate consequences for individuals, organizations, and society. Causes of this dissatisfaction can range from unhealthy ...

Kalman smoothers obtain state estimates in a system with stochastic dynamics and measurement noise. We consider the smoothing problem in a distributed setting, present a cooperative smoothing algorithm for Gauss-Markov linear models, and provide a convergence analysis for the algorithm. An extension of the algorithm that maximizes the likelihood with respect to a sequence of state vectors subje...

This paper describes results regarding cooperative MIMO relaying(CMIMOR), a.k.a virtual antenna arrays(VAA), obtained by Miguel Rodriguez and ongoing work by Fredrik Strömberg. A comparison between CMIMOR, traditional cellular networks and multi-hop networks showed that CMIMOR could increase the link throughput by a factor of 2, in a typical scenario using a relay power allocation algorithm. As...

the objective of the current study is to identify the role of professional development components in developing organizational entrepreneurship in agricultural extension management of kermanshah province. the study was fulfilled by using correlation method and relational-causal model. all the agricultural extension agents in kermanshah province equal to 456 people formed the population of this ...

Relay assisted cooperative wireless communication has been shown to have significant performance gains over the legacy direct transmission scheme for Ad-hoc network. An efficient cooperative Medium Access Control Scheme (MAC) is needed to solve the difficulties induced by relaying and cooperative computing. Another challenging issue is the extension of network lifetime of an Ad-hoc network with...
