This paper projects a novel 3D capacitive accelerometer design to identify a severe accident and initiate airbag deployment systems. It will detect the rapid negative acceleration of the vehicle to avoid the severity of the collision. Such a device demands excellent performance in terms ... En savoir plus
An inactive Demonstration facility for the integrated pyroprocess, named High temperature Electrorefining (HTER) facility is in developing stage. This facility is equipped with several types of pyroprocess equipment such as electro-refiner, salt and cadmium distillation equipment, ... En savoir plus
Phase gratings are used in many applications owing to their high transmission and thus higher diffraction efficiencies. COMSOL is based on finite element modeling and is chosen for 2 reasons; firstly, because it can handle complex 2-D and 3-D geometries and secondly, it can handle the ... En savoir plus
Acoustic metamaterials are structured materials of negative mass density or negative bulk-modulus or both of them. Materials are tailored in sub-wavelength dimensions so as to get these negative properties. This paper compares the result of an experimental investigation of acoustic ... En savoir plus
‘Metamaterial’ is one of the most recent topic in several areas of science and technology due to its vast potential in various applications. These are artificially fabricated materials which exhibit negative permittivity and/or negative permeability. The unusual electromagnetic ... En savoir plus
Understanding the rock structure at nano to micro scale is of growing importance in geology, oil and gas, and hydrology. New approaches that relies on a variety of high resolution 3D imaging techniques offered tremendous potential. These new approaches, in the meanwhile, introduce ... En savoir plus
Vibrating mechanical tank components, such as quartz crystals and surface acoustic wave (SAW) resonators with Q’s in the range of 10e3–10e6, are widely used to implement high-Q oscillators and band pass filters in the radio frequency (RF) and intermediate frequency (IF) stages of ... En savoir plus
High temperature super conducting (HTS) cables are gaining attentions for their ability to transmit more power compared to their convention counterparts with essentially no resistance and electromagnetic emissions. They are also appropriate for solving the grid congestion problem in the ... En savoir plus
The MEMS microphone is also called microphone chip or silicon microphone. The pressure sensitive diaphragm is etched directly into a silicon chip by MEMS techniques and is usually accompanied with integrated preamplifier. Most MEMS microphones are variants of the condenser microphone ... En savoir plus
An attempt has been made to sustain the efficiency of an air pre-heater(APH) in the long run. The APH is modeled using COMSOL Multiphysics in 3D and fed with real life conditions. Upon Heat transfer analysis, the temperature profile was found out and from that, the regions undergoing ... En savoir plus
