In this work, time domain analysis is used to solve Adler’s equation in order to obtain the required time, for an oscillator under external injection, reaching the steady-state condition. Mathematical approach has been applied to fully describe the transient of frequency acquisition in injection-locked LC and Ring oscillators considering their time-varying nature. Then, the analysis is verifie...

In this paper we consider an inverse problem motivated by the use of electroencephalogram (EEG) data to estimate the location and strength of a neural activity in brain tissue. This problem leads to a Poisson type equation with interfaces where the source of activity is described by a model whose parameters must be estimated. Much of the work in this is based on modelling the source as a “dipol...

a simple and sensitive high performance liquid chromatographic method with electrochemical detection is described for the quantitative determination of the amoxycillin and clavulanic acid in pharmaceutical dosage forms. separation of sample components occurs on a reversed phase c18 column with a mobile phase consisting of methanol-water-phosphate buffer. for the amperometric detection, the pote...

spherical granules of the superionic conductor β/β́ lizr2(po4)3 in the range of sub 100 nm sizewere synthesizedvia freeze drying methodand fully reviewed in all aspects. samples were characterized by the x-ray diffractometry (xrd), the thermal analysis (tg, dsc), thefourier transform infra-red spectroscopy (ftir) and the scanning electron microscopy (sem).their structuredepends largely on the me...

This paper presents an analytical modeling method of optimal control variables to maximize output power for switched reluctance generators (SRGs) in single pulse mode operation. This method extends the basic theory of the Stiebler model and utilizes the flux linkage function to express the inductance model of SRG. In this paper, the optimal phase current shape of SRG for maximum output power is...

objective(s):investigation of phase diagram of various drug formulations is effective to predict different phase region of drugs to detect final formula. the purpose of this research was to develop the ternary phase diagrams for a drug microemulsion system consisting of cucurbita pepo (pumpkin) oil, surfactant (tween 80) and deionized water. materials and methods:an electrical conductivity was ...

B1-xLaxFeO3 (x = 0.0, 0.025) crystallites were prepared by chemical solution route. XRD analysis confirmed the phase formation of the materials. Thermal characterization was done by DSC-TGA to confirm crystallization and thermal behavior for phase development. Morphological studies by FESEM showed the agglomerated nature of the ferrite...
