In the present work, we have studied the electron transport properties of single silicon nanowire using Semiconductor Module of COMSOLMultiphysics software. We construct a MSM (metal-semiconductor-metal) model where metal is selected as copper and semiconductor is taken as silicon. ... En savoir plus
An affordable and user friendly digital stethoscope with wireless connectivity is envisioned as an extremely useful tool for heart patients. Our design couples the acoustic pressure from normal stethoscope to a smartphone microphone in an enclosure that is then digitized and sent to ... En savoir plus
Basic Oxygen Steelmaking is the process of refining hot metal obtained from blast furnace using oxygen. In the process, supersonic jet of oxygen is blown over the metal bath resulting in formation of droplets. The droplets mix with slag to form an emulsion in which ... En savoir plus
The rotary kiln process is a commonly practiced method in the industry for producing sponge iron using coal. In the industry, there have been recent reports of premature failures of certain air tubes in a rotary kiln. Most of those cases have concentrated on those air tubes which run ... En savoir plus
A simulation study has been performed, using COMSOL Multiphysics software, for cooling and heating a FR4 PCB and thereafter developing a controller for maintaining the PCB at a fixed temperature for circuit testing at low temperatures. Experimental arrangement was made to cool the PCB ... En savoir plus
Perforated pipes are extensively used to control exhaust noise in automobiles [1-4]. The energy loss associated with the perforations leads to back pressure which needs to be quantified and minimized [5]. An objective approach presented in [6] is the introduction of friction factor for ... En savoir plus
Ellipsometry has been the most efficient and accurate method for determining optical constants of a given material. In this article, we present a novel concept for designing an ellipsometer for Terahertz frequencies based on reflection geometry THz Time Domain Spectroscopy. The present ... En savoir plus
A comparative study is done using optimized single axis accelerometer and dual axis and double gimbal accelerometers are designed with different cantilever beam types i.e. perforated, non perforated, spring type and cross spring type. The models are simulated to find the most sensitive ... En savoir plus
Mung bean is a good source of protein, vitamins, certain minerals and antioxidant compounds for the vegetarian population of the country. During storage, high moisture content of mung bean leads to the maximum quality and quantity losses due to the growth of fungus and insects. Thus ... En savoir plus
We calculate the maximum force acting on the mirror and found it to be 0.54 µN at 700 V. The force magnitude can be improved by increasing voltage and diminishing the separation between plates. The force along X, Y-axis acts towards the center of the plates and in Z direction towards the ... En savoir plus
