This paper describes an automated model selection method for analysing the relationship between the order of the spherical harmonic basis functions used to fit high angular resolution diffusion imaging (HARDI) data and the accuracy of the fitting results. The method performs statistical inference on the spherical harmonic expansion coefficients and uses a backward elimination procedure to remov...

We report a new method for identifying disulfide linkages in peptides using mass spectrometry. This is accomplished by collisional activation of singly charged cationic alkali and alkaline earth metal complexes, which results in the highly selective elimination of hydrogen disulfide (H2S2). Complexes of peptides possessing disulfide bonds with sodium and alkaline earth metal are generated using...

The paper proposes an algorithm to calculate the switching angles using harmonic elimination PWM (HEPWM) scheme for voltage source inverter. The algorithm is based on curve fittings of a certain polynomials functions. The resulting equations require only the addition and multiplication processes; therefore, it can be implemented efficiently on a microprocessor. An extensive angle error analysis...

A large number of harmonics will be generated in the process transforming high frequency and voltage alternating current (AC) into a constant through power conversion system when high-speed motor is used as generator. The phase-shifting reactor to eliminate for generator systems, LCL filter adjustable inductance are supply this paper. can adjust value time according change output inverter. resu...

In this paper we are concerned with the elimination of gamma related errors by employing a simple and direct approach, specifically, for phase measuring profilometry (PMP) methods. The harmonic structure of a gamma distorted fringe is investigated and the implications of j for the PMP algorithm is studied. The minimum requirements in terms of number of Steps for appropriate elimination of j rel...

The reduction of high harmonic content in the grid side current is achieved by different harmonic compensating techniques. In order to accomplish it, selective harmonic compensation is carried out in grid-connected photovoltaic inverters by means of resonant harmonic compensators. The harmonic compensator shown in this paper is lead lag compensator. This paper shows a systematic design procedur...
