Dynamic Multi-Phase Modelling and Optimisation of Fluid Jet Polishing Process
In the Fluid Jet Method, a polishing fluid is compressed and delivered through a nozzle, allowing the spot area to become continuously replenished with abrasives and coolant. Process parameters include: Abrasive type and concentration, Inlet pressure, Nozzle diameter, Impingement angle, ... Per saperne di più

Design of a Miniaturized RF MEMS Based Single-Bit Phase Shifter
This paper presents a novel design of single-bit RF MEMS phase shifter. The basic novelty introduced for phase shifter design in this case, is by scaling down of the lateral dimensions of the conventional RF MEMS shunt switch by 10 times. The Mechanical and Electromechanical analysis ... Per saperne di più
Determination of Fundamental Frequency of a Thin Rectangular Perforated Plate using COMSOL Multiphysics
COMSOL Multiphysics 4.0 is being used to simulate the free vibrations of a plate. The results obtained by simulation in COMSOL are in close proximity to that found by Fast Fourier Transform analyzer and analytical method. As of now the vibration analysis of thin rectangular plates with ... Per saperne di più

MEMS Electrostatic Comb Actuator: A Comparison of Different Structure Designs and Materials using COMSOL 3.5a
The micro machining technology that emerged in the late 1980’s can provide micron sized sensors and actuators. Actuators are used for the transformation of non- mechanical input energy into mechanical output energy. There are many types of micro- actuation mechanisms, most commonly used ... Per saperne di più
Design and Simulation of a Nano-Wire Based Piezoresistive Pressure Sensor
This paper chalks out the design and performance of a piezo resistive surface micro machined circular diaphragm based pressure sensor. A structural deformation in the piezo resistive nano structure placed above the diaphragm will result in varied current density, which is in direct ... Per saperne di più
