Modeling Conventional Swing of a Cricket Ball

R. Latchman [1], A. Pooransingh [1],
[1] University of the West Indies - St. Augustine, St. Augustine, Trinidad and Tobago

Conventional swing is one phenomenon which a bowler uses to gain an advantage over the batsman. This study involved simulating conventional swing in the CFD Module of COMSOL Multiphysics® software and comparing the simulated results with experimental results of previous researchers. The ...

Numerical and Experimental Studies of a Capillary Channel

M. Xu[1], Z. Wu[1], X. Wang[1]
[1]Tsinghua University, Beijing, China

Capillary effects are common in microfluidics due to large surface-to-volume ratio of flows inside microchannels. In biological or chemical analysis, capillary flow is used for the transport of liquid and mixing enhancement, without applying any external means. It’s used in biochemical ... En savoir plus

Numerical Study of Exciton States of Core?shell CdTe/CdS Nanotetrapods by using COMSOL Multiphysics

Y. Yao?and K. Sakoda
National Institute for Materials Science
University of Tsukuba
Japan

This paper showed: * The electronic states of core-shell tetrapod with various shell thickness were calculated. Lowest 20 electron and hole wave functions have A1 or T2 symmetry. * At t=1.2 nm, the carriers separation is not serious, core-shell tetrapod is not apparent type II ... En savoir plus

Novel Simulation of a Voltage-Driven Electro-Thermo-Mechanical MEMS Self-Oscillator

S. Ouenzerfi [1,2,3], H.A.C. Tilmans [2], S. El-Borgi[3,4], X. Rottenberg [2]
[1] KACST-Intel Consortium Center of Excellence in Nano-manufacturing Applications (CENA), Riyadh, KSA
[2] IMEC, Leuven, Belgium
[3] Applied Mechanics and Systems Research Laboratory, Tunisia Polytechnic School, University of Carthage, La Marsa, Tunesia
[4] Texas A&M University at Qatar, Mechanical Engineering Program, Engineering Building, Doha, Qatar

This paper presents the modeling and simulation of electro-thermo-mechanical self-oscillators, an emerging type of M/NEMS-enabled timing devices in which sustaining electronic amplifiers are not required for their operation. Indeed, they realize amplification in the mechanical domain and ... En savoir plus

Use of Simulation in the Development of Next-generation Measurement Standards for Radiation Dosimetry

R. E. Tosh[1], H. Chen-Mayer[1]
[1]NIST, Gaithersburg, MD, USA

Calibration of field instruments used in radiation treatment clinics is currently traceable to NIST primary standards via protocols involving static, flat-field radiation beams. By contrast, radiation beams prescribed for treating cancer incorporate temporal and spatial modulation ... En savoir plus

Development and Optimization of a Microfluidic Device for Magnetic Field Induced Cell Separation

L. Helmich[1], A. Hütten[1]
[1]Bielefeld University, Bielefeld, Germany

Besides conventional laboratory analysis methods, so called micro-total-analysis devices (µTAS) have gained great interest during the last decades. In this work we demonstrate a mechanism for the separation and selection of medical samples that can be applied within these µTAS devices. ... En savoir plus

Design of MEMS Based 4-Bit Shift Register

V. B. Math[1], B. G. Sheeparamatti[1], A. C. Katageri[1]
[1]Basaveshwar Engineering College, Bagalkot, Karnataka, India

This paper presents a unique design of MEMS based 4-bit shift register that perform shifting operation same as logic devices that are composed of solid-state transistors. The MEMS shift register design inherits all the advantages from MEMS switches and thus is expected to have more ... En savoir plus

Ultrasensitive Mass Sensing Through Coupled Microelectromechanical Resonator Arrays

A. R. Hambarde [1], R. M. Patrikar [1],
[1] Visvesvaraya National Institute of Technology, Nagpur, Maharashtra, India

Microelectromechanical coupled resonating arrays are being used for detecting biological and chemical analytes through mass sensing. Such arrays of perfectly identical resonators can be considered as periodic, ordered, non-localized systems. The change in the eigen parameters of the ... En savoir plus
