Tv and or Fm Transmitting Antennas Desien Using Computer Graphic System (RESEARCH NOTES)

The purpose of this paper is three fold. First, the major theoretical pattern relationships of TV and/or FM transmitting antennas are dealt with. Secend, the computer calculation method and designing of such patterns using the given relationships. And third, a method in which a computer graphic system can be used to design such antennas for a specific pattern is introduced and its results are p...

Some notes concerning the convergence control parameter in homotopy analysis method

omotopy analysis method (HAM) is a promising method for handling func-tional equations. Recent publications proved the eectiveness of HAM in solvingwide variety of problems in dierent elds. HAM has a unique property whichmakes it superior to other analytic methods, this property is its ability to con-trol the convergence region of the solution series. In this work, we claried theadvantages and ...

Sandrine Martin, Michael C. Hamilton and Jerzy Kanicki The University of Michigan, Department of Electrical Engineering and Computer Science, Solid-State Electronics Laboratory, 1067 BIRB, 2360 Bonisteel Blvd, Ann Arbor, MI 48109-2108, USA. ABSTRACT Organic polymer based thin-film transistors (OP-TFTs) look very promising for flexible organic electronics. In this paper, we describe devices base...

Evidence of the Potential Shift Mechanism in Crevice Corrosion (RESEARCH NOTES)

Previous research has indicated a qualitative resemblance between the current distribution along actively corroding crevice walls and currents measured in corresponding anodic polarization plots. Using detailed measurements of the potential gradient along the crevice, a semi-quantitative current distribution was calculated for the crevice wall using a double numerical differentiation method. Th...
