Design and Testing of Superconducting Microwave Passive Components for Quantum Information Processing
Abstract
We report on the design, fabrication and testing of
two superconducting passive microwave components, a quadrature
hybrid and a 20 dB directional coupler. These components
are designed to be integrated with superconducting qubits or
Josephson parametric amplifiers and used in quantum information
processing applications. For the coupler, we measure return
loss and isolation 20 dB, and insertion loss 0.3 dB in a 2 ....etc

RADAR AND SYNTHETIC APERTURE RADAR BASICS
PRINCIPLES OF RADAR
HOW DOES RADAR WORK?
• RADAR = Radio Detection And Ranging
• Since radar pulses propagate at the speed of light, the difference to the “target” is proportional to the time it takes between the transmit event and reception of the radar echo

Active and Passive Voice


In the active voice, the subject of the sentence performs the action:
I aced the exam.
Subject/actor verb object/thing acted on
In the passive voice, the object of the action becomes the subject of the sentence, and
the actor appears in a prepositional phrase, or is absent from the sentence:
The exam was aced (by me).
Subject verb actor/object of prepositional phrase
► Use the active voice when the actor’s identity is important.

ABSTRACT
This dissertation proposes simple and efficient control algorithms for seismically excited structures using MR dampers and a smart passive system based on MR dampers. Magnetorheological (MR) dampers are one of the most promising control devices for civil engineering applications to earthquake hazard mitigation, because they have many advantages such as small power requirement, reliability, and low price to manufacture. A number of control algorithms have been adopted for semi active systems including the M ....etc

INTRODUCTION

Miniaturization has been a key contributor to advances in electronic technology. Certainly, miniaturization has been made possible mostly through remarkable breakthroughs in reducing the size of active components. But as integrated circuits get smaller and more complex, there is an increasing need to also reduce the space required for the supporting passive components. If any of the electronic devices such as cellphone, camcorder, computer, or other consumer electronics system is opened, one or two circuit boards on which are mo ....etc

Abstract

This work features the design and a control scheme for an active multi-degree of freedom kinematic pair piezoelectric robot. We introduce the piezoelectric active kinematic pair where the joints between the links are made from piezoactive material. The objective is to design an energy efficient underactuated precision micromanipulator with a fault-tolerant design where not all joints require actuators. Typical configuration of this type of piezoelectric robot is that it consists of several identical joints, i.e. kinematic pairs of t ....etc
