A series of heterostructure designs low-voltage InP homothyristors have been investigated using numerical simulation methods. The design with a space charge layer formed in the p-base region n-p-n transistor part was considered as base one. dynamic characteristics and processes that determine rate transition to on state are investigated. It is shown thickness increases from 1 2.6 μm, maximum on...

This paper presents the design of a 6-DOF desk-top magnetically levitated force-feedback j o ystick utilizing voice-coil actua-tion. Relative to prior designs Hollis et. this haptic interface features a novel geometry, a n o vel optical sensor and optimized actuation. These allow for all the electronics including the control microprocessor to be integrated in its base, with the device tapering ...

In this paper, a new VLSI architecture is provided for the application of quad-input and dual-output Fuzzy Logic Controller (FLC) with maximum seven fuzzy membership functions. Our approach is based on classical three stage implementation process – fuzzification, rule inference and defuzzification cores. An innovative design methodology is proposed by splitting the process between DSP processor...

In the present work, a methodology that allows optimizing permanent magnet synchronous generator (PMSG) design by establishing limit values of radius and length maximize efficiency for nominal parameters wind turbine is developed. The consists two fundamental models. One model calculates from base, other optimization determines optimum generators according to criteria maximum with minimum weigh...

in order to study the influence of compost and biofertilizer on yield and essential oil of dill (anethum graveolens l.), an experiment was conducted as factorial experiment in the base of randomized complete blocks design with eight treatments and three replications at research field of agriculture company of ran in firouzkuh of iran in 2012. the factors were compost in four levels (0, 5, 10 an...

The purpose of this paper is to verify the applicability of the prototype of the Neural Network base model for Optimum Structural Design(NNOSD) to search the optimum design in all cases immediately. NNOSD suggest the procedure of the optimum design and the proper values of the neural network variables(training pattern, number of hidden neurons, maximum training error, steepness coefficient, lea...

lentil (lens culinaris. medik) is one of the major cool season pulse crops which could suffer damage under severe cold. some physiological parameters such as electrolyte leakage (el) have been used to assess the response of crops to cold conditions. in order to evaluate the possibility of using the el index for assessing the freezing tolerance of lentil genotypes, a factorial experiment carried...
