The objective of the work is to propose a reliability enhancement model for antigen detection system (ADS) using bio MEMS based cantilever array sensors using heterogeneous modular redundancy technique. The reliability of the ADS is expressed in terms of the constituent sub systems which are heterogeneous not only in their respective structures and behaviors but also in their forms. The possible ...

Proton exchange membrane fuel cells (PEMFCs) were investigated using COMSOL Multiphysics with the AC/DC Module and Chemical Engineering Module. Simulation may be used to increase the performance while decreasing the cost of the catalyst later (CL). Experimental validation of single and multi-layer CL was performed for varied PBI electrolyte content. The validated model was used to investigate ...

Cryotherapy and thermotherapy are common methods of treatment for acute injuries ranging from ankle sprains to complex surgery. The idea behind such treatment is that a change in temperature will reduce pain and constrict fluctuations in blood flow at the targeted area. The purpose of this study is to simulate the vascularized tissue reaction and the resulting blood flow fluctuation from thermal ...

A pocket-size portable particle size detector for diesel and cigarette smoke aerosols is being designed using particle size and composition methods. Aerodynamics, fluid properties, material composition and aerosol composition are taken into account. Testing methods for the design include using an impactor and virtual impactor with two quartz crystal resonators to determine particle composition ...

Due to computational considerations most models of lithium storage particles in batteries incorporate spherical particles. However most storage particles used in battery electrodes tend to be irregular in shape with sharp edges and extended aspect ratios. The change of the relative surface area to the volume of the particle can lead to a change in the stress response of the particle for the same ...

The numerical study of temperature and acceleration sensitivities of a dual cavity Fabry-Perot (FP) interferometer is carried out using finite element method. The optical cavities are formed by machining two side-by-side circular bore of 12 mm each on a monolithic block of low expansion material. One cavity will be used to generate broadband channel spectra for accurate wavelength calibration of ...

Introduction: In inductively coupled plasma (ICP) systems the inductive antenna is coupled to the excited plasma inside the low pressure gas reactor. A multi-ICP system can be used for increased area processing and provide additional variables for controlling the plasma. However, assembling the source from individual sources changes the symmetry of the system. Simulation of plasmas in ...

All particles in suspension have a zeta potential, or surface potential. Its measurement is extremely important for predicting the formulation stability across a wide range of industries including food, ink and pharmaceuticals, water purification and medical devices. Zeta potential is not measurable directly but it can be calculated from an experimentally determined electrophoretic mobility. ...

A small particle or a nano-sized object placed in a liquid is subject to random collisions with solvent molecules. The resulting erratic movement of the object is known as Brownian motion, which, in nature, cannot be used to any practical advantage both in natural systems (such as biomolecular motors) or by artificial devices. If energy is supplied by external source or by chemical reactions, ...

A very simplified system for high voltage test is studied, considering reason for voltage holding failures which are not covered by conventional and local design criteria. A first understanding of the problem is obtained by solving the electrostatic potential in a 2D axis symmetric geometry, considering in detail the electrode shapes, and following a cascade of particle between opposite ...
