Compound semiconductor devices are commonly used in today’s wideband communications systems. In particular, they are indispensable to build the front-end stage, which is required to process high-frequency signals. Introduction of resonant-tunneling diodes (RTDs) to the front end would result in even better system performance. In the long term, such efforts are expected to pave the way for post-...

The world has become a global village. Today applications are developed which require sharing of resources dispersed geographically to fulfill the need of the users. In most cases applications turn out to be time bound thus leading to Real Time Distributed System (RTDS). Online Banking, Online Multimedia Applications, Real Time Databases, and Missile tracking systems are some examples of these ...

This paper presents the design, fabrication and characterization of temperature microsensors based on Resistance Temperature Detectors (RTDs) with a meander-shaped geometry. Numerical simulations were performed for studying sensitivity RTDs according to their windings numbers as well optimizing layout. These fabricated using well-established microfabrication photolithographic techniques. The se...

Real-time control of smart grid will require fast and accurate implementation of intelligent monitoring and decision making techniques. Intelligent methods with faster speed and better accuracy will be possible by implementing in parallel on high performance computing platforms. Such methods need to be rigorously tested in simulations before implementing in actual systems. Therefore, integratio...

The modeling and simulation of photovoltaic power generation system has become an important issue in the field of power generation. Research on the characteristics of photovoltaic (PV) grid-connected system by hardware-in-the-loop simulation could provide convenient experiment condition and accurate result. This article designs a photovoltaic grid-connected simulation platform for digital/physi...

We have estimated the performance of a flash analog-to-digital converter (ADC) that consists of ternary quantizers and a ternary-to-binary encoder using resonant-tunneling diodes (RTDs). The ternary quantizers consist of resonant-tunneling monostable-to-multistable transition logic (MML) circuits, while the encorder consists of multiple-valued multiple -input monostable-to-bistable transition l...

Introduction: Negative resistance elements are important components in oscillator circuits and form the basis of many other nonlinear circuits. Resonant tunnelling diodes (RTDs) have attracted much attention owing to their wide-bandwidth negative differential resistance (NDR), up to hundreds of GHz [1]. Because RTDs can be easily integrated in electronic and optoelectronic circuits, the applica...

Theta-defensins (θ-defensins) are macrocyclic antimicrobial peptides expressed in leukocytes of Old World monkeys. The peptides are broad spectrum microbicides in vitro and numerous θ-defensin isoforms have been identified in granulocytes of rhesus macaques and Olive baboons. Several mammalian α- and β-defensins, genetically related to θ-defensins, have proinflammatory and immune-activating pro...

Nowadays, industry has successfully used Network Control Systems (NCS) therefore several lines of research have arisen. A NCS is a current application of a Real-Time Distributed Systems (RTDS), composed of a number of nodes capable of developing a complete control process. In this systems several nodes exchange information through a communication network to achieve specific control goals, never...
