Silk fibers are a remarkable material made of proteins possessing excellent mechanical properties that match or even outperform, in some aspects, high performance such as Kevlar and steel. can be further produced recombinantly, allowing the possibility for genetic modification, enhancing silks’ already impressive range benefits. Thus far, little research has explored incorporating silk-based ma...

Abstract This paper analyzes the influence of harmonics on system and importance power factor correction. According to requirements aircraft use, an active correction based three phase six switch topology is designed. The article working process control method system, then designs a rectifier convert 220V/400Hz AC provided by DC high. Moreover, performance tested.

In this work a low power, low voltage and high gain operational amplifier is proposed. For this purpose a negative resistance structure is used in parallel with output to improve the achievable gain. Because of using self cascode transistors in the output, the proposed structure remains approximately constant in a relatively large output voltage swing causing an invariable gain. To evaluate the...
