Authors : C. Ononogbo,O.C. Nwufo,G.N. Nwaji,E. C. Nwosu,P. C. Nwadinobi,C.A. Okoronkwo,J.O. Igbokwe,E.E. Anyanwu,


The thermal profile of an exhaust gas waste heat recovery (WHR) crop dryer is presented. The dryer uses a parallel flow heat exchanger to recover the exhaust gas waste heat of a diesel engine generator for the drying of food crops. No-load tests of the assembled test rig were conducted to study the temperature profile and heat transfer rates in the dryer at varying inlet ambient air velocities....

Technological Process of Increasing the Density of Elements  in a Compact Transimpedance Amplifier based on Heterostructures, Porosity and Missmatch  Induced Stress of Materials
Authors : E.L. Pankratov,


In this paper, we introduce an approach to increase the density of field-effect transistors framework a compact transimpedance amplifier. In the present theoretical framework, the approach we consider in the manufacturing the inverter in heterostructure with specific configuration. Several required areas of the heterostructure should be doped by diffusion (alternatively they could be doped by...

An Approach to Increase Integration Rate of Elements of a Dynamic Comparator
Authors : E.L. Pankratov,


In this paper we introduce an approach to increase integration rate of elements of a dynamic comparator. In the framework of the approach we consider a heterostructure, which consists of a substrate and an epitaxial layer with special configuration. After that we consider doping by diffusion or ion implantation of several specific areas of the epitaxial layer with annealing of them in the...

Modeling and Analysis of the Effects of Surface and Interface States on the Photocurrent and the Efficiency of a Solar Cell Based on n+npp+ Structure
Authors : E.M. Keita,Y. Tabar,B. Ndiaye,A.A. Correa,C. Sene,B. Mbow,


In this article, we study the influence of interface and surface recombination effects on the performance of a solar cell and on the photocurrent profile. This study is applied to chalcopyrite thin film solar cell comprising 4 active layers following the model ZnO(n+)/CdS(n)/CuInS2(p)/CuInSe2(p+) where CuInS2 represents the base and CuInSe2 the substrate. It is based on the continuity...
