Articular cartilage is an avascular connective soft tissue in the diarthrodial joints and functions in a highly demanding mechanical environment. The degeneration or wear of the cartilage is a huge problem that effects millions of people every year. The long term objective of the present work is to develop an analytical articular cartilage growth model. A simplified 2D axisymmetric ...

Carbon Nanotubes (CNTs) have remarkable mechanical, thermal and electrical properties. The properties of CNTs depend on atomic arrangement (how the sheets of graphite are rolled), the diameter and length of the tubes and morphology of nanostructure. In this paper effective elastic properties of CNT based polymer composites are evaluated using a square Representative Volume Element (RVE) in ...

Freeze-drying is a popular method of producing shelf stable particulate products and is of particular value for drying thermally sensitive materials (volatiles and biological based), which can be heat damaged by higher temperature methods, such as spray-drying. Porous structures are formed by the creation of ice crystals during the freezing stage, which subsequently sublime during the drying ...

Thermocouples have been used for measurement of temperature ever since the discovery of Seebeck effect. Though the voltage output of a thermocouple is a function of the temperature difference between hot and cold junctions, the response time and the magnitude of voltage depends on the geometry and material of the thermocouple also. This report deals with the study of the ...

Curved cone corrugated ground plane conical antenna has been designed and analyzed using Finite Element Method. In this paper, we introduce a novel Curved cone corrugated ground plane conical antenna for ultra-wideband (UWB) applications. The antenna is composed of curved cone with narrow corrugation on finite ground plane and fed by a 50? coaxial cable. The designed antenna operates over ...

Arterial disease, especially Coronary Artery Disease (CAD) is one of the leading causes of premature morbidity and mortality. During the flow, blood interacts with vessel wall mechanically and chemically which modulates the plaque formation in blood vessel leading to coronary artery diseases. Here we propose to simulate a MEMS based flexible flow sensor based on anemometer principle designed to ...

MEMS(Microelectromechanical systems) based energy harvesting is process of extracting energy from natural resources in small amounts. Here, number of (millions) small energy harvesting modules lead to substancial energy. In this design, a piezoelectric material is used to scavenge energy from natural resources like radioactive source. COMSOL Multiphysics is used to model and simulate a ...

The objective of this paper is to design a 3D Gas Sensor for sensing Hydrogen gas and to increase the conductivity at nano level. In this novel design, nanorods act as the sensing layer. The sensitivity towards gas adsorption is found to be increased due to its high surface to volume ratio. The total displacement and voltage on intermediate layer after gas adsorption will be changing by varying ...
