This investigation deals with a mathematical model for a distribution transformer including saturation effect. To this end, the equations related to a three phase transformer are specified and the effect of an inter-turn fault is included. Naturally by applying an inter-turn fault the inductance and resistance matrix will change. Thus, unknown quantities of inductances and resistances for compl...
Beyond the natural proteome, high-throughput mutagenesis offers the protein engineer an opportunity to "tweak" the wild-type activity of a protein to create a recombinant protein with required attributes. Of the various approaches available, saturation mutagenesis is one of the core techniques employed by protein engineers, and in recent times, nondegenerate saturation mutagenesis is emerging a...
the quality of the river water is assessed in different months in different stations to evaluate the change in the quality in re1ation with the various point sources along the river. thirteen parameters were measured in the samples manually taken from three meters off shore in 20 cm. depth in four points representing the quality in four reaches under consideration. the results revealed that nat...
Different cascode circuits are investigated with regard to their suitability for low-voltage and low-current circuits. A generalized circuit representation is introduced and different cascode circuits are discussed with respect to their small-signal parameters as well as their associated dynamic output ranges. The output voltage ranges for saturation operation of the different cascode circuits ...
A two-dimensional along-the-channel CFD (computational fluid dynamic) model, coupled with a twophase flow model of liquid water and gas transport for a PEM (proton exchange membrane) fuel cell is described. The model considers non-isothermal operation and thus the non-uniform temperature distribution in the cell structure. Water phase-transfer between the vapour, liquid water and dissolved phas...
: Induction generators are gaining the popularity due to its simplicity and no synchronization problem. However the major drawback of this machine is its additional reactive burden on the system, where it is connected. In this paper an attempt is made to explore the performance of a grid connected induction generator (GCIG) due to weak grid conditions i.e. voltage and frequency fluctuations. It...
cdse nanostructures were synthesized by using green chemical route as starch was used as capping agent. xrd, hr-tem, sead, uv and pl studies were made for structural and optical properties of the prepared sample. film morphology and the thickness measurement of n-cdse were carried out with afm analysis. i-v characteristics curve of this junction confirmed the formation of schottky contact betwe...
The magnetization behavior of long nanowires with square cross section under the influence of strong perpendicular spin-polarized current is studied theoretically. The study is based on Landau-Lifshitz-Slonczewski phenomenology. Without the current the wire is magnetized uniformly along its axis. For small currents the wire magnetization remains uniform, but it inclines with respect to the wire...
