In the present study, supercritical carbon dioxide (SC-CO2) extraction of seed oil from winter melon (Benincasa hispida) was investigated. The effects of process variables namely pressure (150–300 bar), temperature (40–50 °C) and dynamic extraction time (60–120 min) on crude extraction yield (CEY) were studied through response surface method

An experimental investigation of a snake robot has been discussed and analyzed in this paper. This experimental investigation involves elementary possessions of the angular velocity of a snake robot by carrying out serpentine locomotion. This is a preparatory experimental work to go for the real snake experiment involving snake locomotion in future

The objective of this chapter is to estimate 2D human pose for action recognition and especially for sign language recognition systems which require not only the hand motion trajectory to be classified but also facial features, Human Upper Body (HUB) and hand position with respect to other HUB parts. We propose an approach that progressively reduce

Throughout the technological advancements, electronic devices are getting high dense and less expensive in day by bay. Thus, significantly reducing the production cost is the vital issue in order to produce more competitive device with maintaining its standard in all expect. Therefore, introducing new compact contact in high-Hertz stress with low n

An algorithm for undertaking indoor localisation of multi-robot reconnaissance mission through collaboration has been presented in this paper. A set of communication techniques, an algorithm for sharing behavior for positioning of agent robots, and appropriate attitude which is useful for a group of robots to work together, are developed for collab

For indoor local area network (LAN) the Polymer optical fiber (POF) is mostly appropriate, because of its large core diameter and flexible material. A 1×2 optical switch for indoor LAN using POF and a shape memory alloy (SMA) coil actuator with magnetic latches was successfully fabricated and tested. To achieve switching by the movement of a POF,

The development of a miniature; size, light and high performance electronic devices; has been accelerated for further development. In commercial stamping method, connector pitch size (radius) is more than 300μm due to its size limitation. Therefore, the stamped contact hertz stress becomes lower and less suitable for fine pitch connector. To overc

Enable the design of a small contact spring for applications requiring high density, high speed and high durability. A low normal force (LNF) contact spring with high performance is fabricated using a unique combined MEMS photo resist lithography and electro fine forming (EFF) technology. Reducing a total contact material cost of a connector, a hig

Polymer optical fiber (POF) is suitable for indoor local area network (LAN), because of its flexibility and its ease of connection due to its relatively large core diameter. A 1×2 optical switch for indoor LAN using POF and a shape memory alloy (SMA) coil actuator with magnetic latches was successfully fabricated and tested. To achieve switching b

The measure of quality assurance evaluation plays a vital role in quality enhancement determinations, precisely in university educational institutions. Recently, Nigeria Government had to embark on laudable policy programmes that will enhance the quality of university educational institutions. But to fulfill this responsibility, is frequently thwar
