this paper is concerned with the estimation of total factor productivity (tfp) growth for the iranian electric utilities during the period 1980-1993 on the basis of panel data. a translog cost function is used which accommodates firm - specific variability through a one - way error component model. the results show that the iranian electricity supply industry experienced increasing returns to s...

This paper evaluates the Total Vector Error of an estimated Phasor as define in IEEE C37.118 standard within different medium access in Local Area Networks (LAN). Three different LAN models (CSMA/CD, CSMA/AMP and Switched Ethernet) are evaluated. The Total Vector Error of the estimated Phasor has been evaluated for the effect of Nodes Number under the standardized network Band-width values defi...

The loss probability of a queueing system provides, in many cases , insuucient information for performance evaluation, for example , of data link layer protocols and applications with forward error correction. This paper evaluates and characterizes the correlation between packet losses for two queueing systems in discrete time that are motivated by BISDN applications. The rst, a two-class discr...

error is an inevitable part of life and cannot be completely eliminated, but it can be minimized. a root cause analysis is a technique for understanding the systematic error causes that is involved beyond a person or people to implement an errors and including field and environmental causes of errors when occur in this situation too. an important factor of an error occurrence is a root cause (c...

In Xu [11], a class of parametrized flux limiters is developed for high order finite difference/volume essentially non-oscillatory (ENO) and Weighted ENO (WENO) schemes coupled with total variation diminishing (TVD) Runge-Kutta (RK) temporal integration for solving scalar hyperbolic conservation laws to achieve strict maximum principle preserving (MPP). In this paper, we continue along this lin...

Consider the multiple testing problem of testing null hypotheses H1, . . . ,Hs. A classical approach to dealing with the multiplicity problem is to restrict attention to procedures that control the familywise error rate (FWER), the probability of even one false rejection. But if s is large, control of the FWER is so stringent that the ability of a procedure that controls the FWER to detect fals...

We propose a joint source channel coding system for fractal image codes in which both a transmission bit rate allocation scheme and an unequal error protection strategy are considered. We express the total distortion in terms of the source distortion and the channel distortion. Then, we allocate the available total bit rate between the source code and a range of error-correcting codes using a L...
