the effects of pulsed electric field (pef) on the cell disintegration of sugar beet were studied. field strength (0.5kv/cm to 6kv/cm), pulse number (1 to 100 pulses) and capacity of capacitors (0.5 f to 32 f) were evaluated on degree of cell disintegration and consumed energy in pef treatment. the field conditions of 1 and 2 kv/cm, 8 f with 20 and 10 pulses respectively disintegrated the cel...

in scpc-dama satellite networks, the baseband rrc pulse shaping is utilized to reduce the bandwidth and inter symbol interference (isi). but the variation in carrier's envelope, which expands the spectrum and ultimately increases the bandwidth, causes isi and quadrature channel crosstalk (qcc). the goal of this paper is to introduce a method to shape baseband rrc pulses, in order to make a near...

Abstract: The reliability analysis of load-sharing m-out-of-n systems where the workload is shared by the remaining working units when a unit fails is proposed in the paper. General expressions are provided for the m-out-of-n system reliability by arbitrary probability distributions of time to failure of units. Simplified methods are given for computing the survivor function in cases when the t...

Long-run average properties of probabilistic systems refer to the average behavior of the system, measured over a period of time whose length diverges to innnity. These properties include many relevant performance and reliability indices, such as system throughput, average response time, and mean time between failures. In this paper, we argue that current formal spec-iication methods cannot be ...

This article shows the use of lexical functions in the MorDebe lexical database system. Lexical functions are used in MorDebe to bridge the gap between derivation and inflection – to model relations between word-forms that are derivational from one perspective but inflectional from another. However, lexical functions in MorDebe range over lemmas rather than word-meanings and are hence significa...

The daily volatility is typically unobserved but can be estimated using high frequent tick-by-tick data. In this paper, we study the problem of forecasting the unobserved volatility using past values of measured volatility. Specifically, we use daily estimates of volatility based on high frequency data, called realized variance, and construct the optimal linear forecast of future volatility. Ut...

The effect of supervisory control on a redundant database unit representing a command and control (C2) system that supports air operations is investigated through simulation. Several supervisory control policies are considered. They authorize restoration and/or routing upon the failure of a server in the system. The performance of the modeled system under these policies is evaluated based on th...
