technical and scale efficiencies of cotton farms, in khorasan province, were estimated through the parametric approach during the period 2000-2003. efficiency was estimated through stochastic translog frontier production function based on panel data. results indicated that technical efficiency wa rated as less than scale efficiency. means of technical and scale efficiency were found to be 63 an...

this research covered three villages in kura local government area of kano state. the study described the socio-economic characteristics of maize producers and their production techniques and also determined the profitability and resource use efficiency in the maize production. structured questionnaires were used for primary data collection and 40 small scale producers were purposively selected...

This paper specifies an empirical framework for estimating both technical and allocative efficiency, which is applied to a large panel of European banks over the years 1996 to 2003. Our methodology allows for self-consistent measurement of technical and allocative inefficiency, in an effort to address the issue known in the literature as the Greene problem. The results suggest that, on average,...

Let $f \in L^{2}(\mathbb{R}^n)$ and suppose we are interested in computing its average at a fixed scale. This is easy: pick the density $u_{}$ of probability distribution with mean 0 some moment desired scale compute convolution $u_{} * f$. Is there particularly natural choice for $u$? question studied space theory Gaussian popular answer. We were whether canonical $u$ can arise from new axiom:...

DNA replication is a key process in cell division cycle. It is initiated in coordinated manner in several species. To understand the DNA replication in a species one needs to measure the half replication timing (or replication timing) and the efficiency of replication which vary across genome in higher eukaryotes. In the previous studies, no direct assessment of replication efficiency on a geno...

Adaptive coded modulation (ACM) is a promising tool for bandwidth-efficient transmission in a fading environment. The main motivation behind employing ACM schemes is to improve the spectral efficiency of wireless communications. In this paper, we present a method This work was supported in part by the NTNU project IKT-webtek (http://www.ntnu.no/ satsingsomraader/ikt/focus1.htm), in part by the ...

the purpose of this article is the measurement of technical efficiency and returns to scale using data envelopment (dea) approach. in this study, we have measured efficiency quantity and economies of scale for state owned insurance and private companies for 1384-1385 periods. the results reveal that in the dea with the assumption of variable returns to scale, iran, tosee and razi companies have...

In wireless networks consisting of sensors and mobile devices, battery power is a severe resource constraint. Energyefficient communication techniques are therefore crucial to the long-term survivability of the network. In communication theory, it is well known that for a bandlimited additive white Gaussian noise (AWGN) channel with bandwidth W and onesided noise spectral level N0, the minimum ...
