The exponential growth in wireless systems require rapid prototyping of radio frequency circuits (RF) using computer-aided design (CAD) enabled models. Most of the RF circuits (e.g. switches, amplifiers, mixers, etc.) use transistors as their active component for a variety of key functions. This thesis deals with application-oriented empirical modeling of high electron mobility transistors (HEM...

Abstract High mass transfer rate is a key advantage of microreactors however, under their characteristic laminar flow, it dominated by slow diffusion rather than fast convection. In this paper, we demonstrate how the configuration inlet, i.e. mixers, can promote different flow patterns to greatly enhance mixing efficiency downstream. A systematic evaluation and comparison widely adopted mixers ...

The control of blend morphologies during process is of prime importance in order to predict the final properties of polymer blends. A coextrusion technique combined with static mixers was developed in order to smartly blend polymeric melts and to optimize the blend morphologies during the flow in static mixers [1]. The aim of this paper is to study the evolution of those blend morphologies duri...

We discuss performance of submicron size hotelectron bolometer (HEB) mixers made from thin MgB2 superconducting films. With a superconducting transition temperature of 30K, such THz mixers can operate with high sensitivity at temperatures up to 20K. Due to very small dimensions local oscillator (LO) power requirements are rather low. In the intermediate frequency (IF) band of 1-3GHz the double...

Domestic Hot Water (DHW) production constitutes a significant proportion of the energy demand modern buildings, and as building envelope is improved share increases. This article shows results from measurement campaign on two equal hotel blocks, in same hotel. There are different basin shower mixing taps installed one with original mixers (13–14 l/min) touch-free operated water saving (5–6 l/mi...
