[1]School of Mechanical Science & Engineering, Huazhong University of Science and Technology, Wuhan, China

Steel tubes are widely used in industries. In order to ensure the safety and reliability of industrial processes, electromagnetic acoustic transducers (EMATs) based guided wave technology has been developed for inspecting stainless steel tubes regularly. Theoretical models and finite ... En savoir plus

Dynamic Contact & Fatigue Analysis of a CV Boot (Gaiter) Design

M. Yeoman[1], R. Damodharan[1]
[1]Continuum Blue Ltd., Ystrad Mynach, UK

CV boots or gaiters are rubber like material used to cover & protect moveable or articulating components such as CV joints of a vehicle. These are primarily used to protect the articulating joint, by preventing the components from being exposed to the surrounding environment, the ... En savoir plus

Development of MEMS-based Pressure Sensor for Underwater Applications

Aarthi E[1], Pon Janani S[1], Vaidevi S[1], Meenakshi Sundaram N [1], Chandra Devi K[1]
[1]PSG College of Technology, Coimbatore, Tamil Nadu, India

Blind cave fish are capable of sensing flows and movements of nearby objects even in dark and murky water conditions with the help of arrays of pressure-gradient sensors present on their bodies called lateral-lines. To emulate this functionality of lateral-lines for autonomous underwater ... En savoir plus

Optimization of Design Parameters of a Novel MEMS Strain Sensor used for Structural Health Monitoring of Highway Bridges

H. Saboonchi, and D. Ozevin
Civil Engineering Department
University of Illinois at Chicago
Chicago, IL

The novel Micro Electro Mechanical System (MEMS) based Piezoresistive stain sensor is presented in this paper. The main goal of this sensor is to monitor the localized strain in the highway bridges especially near the crack tips. Monitoring the crack growth on the bridges can lead to ... En savoir plus

Analysis of a Prototype MRI Hybrid Birdcage RF Coil with Uncertainty Quantification (*)

J. T. Fong [1],
[1] National Institute of Standards & Technology, Gaithersbug, MD, USA

INTRODUCTION. In a magnetic resonance imaging (MRI) system (see Fig. 1), it is necessary to excite the nuclei of a patient into coherent precession for imaging. This requires coupling between the nuclei and a source of radio frequency (RF) power (the transmitter). To receive a ... En savoir plus

Groundwater Modeling as an Assessment Tool for Underground Mines Located in Fractured Massifs
