This paper presents a methodology to compute the inductances of the abc induction motor model considering mixed eccentricity. The winding function method (WFM) is employed to calculate the magnetizing inductances. Moreover, the air gap is approximated by an expression which…

The present article shows the design and test of a unified-processing device for detection and demodulation of narrow and broadband communication signals, as well as navigation signals from GLONASS and GPS systems. The specific processing for each type of signal…

We present radial-velocity observations from DAO and Cambridge, from which we derive orbital elements. HD 23052 is a G-type main-sequence object which has been regarded as a solar analogue, in an orbit of period nearly three years. HD 90512 is…

Strömgren uvby - β photoelectric photometry of the stars RU Piscium, SS Piscium and TU UMa is reported.

In this work an alternative approach for diffuse lighting and specular reflections is presented that uses YIQ color space instead of traditional RGB color space. The classical illumination algorithms that rely on RGB color space may lead to unrealistic results…

This paper describes an improved sensorless vector control strategy for a squirrel cage induction generator used in variable speed wind energy conversion systems (WECS). The main goal is to design a robust control algorithm immune to generator parameter variations. In…

Selecting an optimal threshold value is the most important step in image thresholding algorithms. For a bimodal histogram which can be modeled as a mixture of two Gaussian density functions, estimating these densities in practice is not simply feasible. The…

Motivated by a problem faced by road construction companies, we develop a new model to obtain an optimal transportation schedule of mobile machines which have to travel to execute tasks. In this problem, each task is characterized by the location…

This paper presents the sensitivity analysis of the behavior of a synchronous machine using the winding function theory considering the effect of static air-gap eccentricity. The winding function theory as a method to calculate the inductances of synchronous machines from…
