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

SUMMARY
Passive radar systems that exploit illuminators of opportunity, such as FM radio and television broadcasts, to
detect and track airborne targets have been under development for over a decade. This paper reviews efforts
to add radar imaging and target recognition capabilities to such systems. We discuss recent developments
along two parallel threads:
1) Target recognition via radar cross section (RCS) profiles: In this approach, databases of the RCS of
targets at different incident and observed angles are created using meth ....etc

The solar house: passive heating and cooling


ABSTRACT:

Passive solar heating and passive cooling—approaches known as natural conditioning—provide comfort throughout the year by reducing, or eliminating, the need for fossil fuel. Yet while heat from sunlight and ventilation from breezes is free for the taking, few modern architects or builders really understand the principles involved.

Abstract
One of the problems in low-cost passive RFID tagsis that they do not provide authentication andprivacy. To address this problem Liu et al.proposed the PAP protocol for low-cost passiveRFID tag in ICCST 2009. The PAP is has lowcomputation and ensures privacy andauthentication between tags and readers, especiallydesigned for SCM (Supply Chain Management)and small shops. We present an IPAP: ImprovedPrivacy and Authentication Protocol. IPAP has 2-bits privacy bit to support refined privacyprotection and lower computation overheadc ....etc

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.
A ....etc

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

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

Stereoscopic Passive Millimeter-Wave Imaging and Ranging

Thomas Lüthi and Christian Mätzler, Senior Member, IEEE



Abstract—

This paper presents the first stereoscopic range measurements
at a wavelength of 3.3 mmand discusses the accuracy of
this new method. The synthesis of passive millimeter-wave imaging
and stereoscopy combines the advantages of both principles, naturally
looking high-contrast images and superior poor-weather performance
(compared to visible and infrared ....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—Faulty components in a network need to be localized and repaired to sustain the health of the network. In this paper, we propose a novel approach that carefully combines active and passive measurements to localize faults in wireless sensor networks. More specifically, we formulate a problem of optimal sequential testing guided by end-to-end data. This problem determines an optimal testing sequence of network components based on end-to-end data in sensor networks to minimize expected testing cost. We prove that this problem is NP-hard ....etc
