an important problem in performance evaluations of irrigation systems is the difficulty of the determining share of structural and operational elements and determining improvement solutions. in most studies, the combined impact of structural and operational elements on the performance of irrigation systems is assessed. some researchers try to separate the effects of structural and operational e...

In this paper I examine some of the factors influencing technology development and attempt to explain whether CLIA '88 enhances the opportunities or exacerbates the problems for U.S.-based technology development. The viewpoint I express is concentrated on the clinical chemistry segment of the diagnostics arena.
In service sector, there are challenges in keeping an optimum balance between customers' demand and availability of resources. This problem is going to be more intense in the health sector due to the fact that both arrival and service times are random. Therefore, designing the service environment by keeping the optimum balance between customers’ demand and available resources is becoming a seri...
Recently, orthogonal frequency division multiplexing (OFDM) has been extensively used in communications systems to resist channel impairments in frequency selective channels. OFDM is a multicarrier transmission technology in wireless environment that use a large number of orthogonal subcarriers to transmit information. OFDM is one of the most important blocks in digital video broadcast-terrestr...
One of the main problems of field effect diode (FED) is the increasing of its turn-off current as the channel length decreases. Thus, in this paper, a new structure is presented which decreases the injection of extra carriers to the channel and also increases the control of the gate over the channel by reducing the portion of channel shared with the source and drain regions and without the need...
