Piezo-resistive method for tuberculosis detection using microcantilever biosensor

Abstract: Microcantilever device is utilized in several biosensors for detection of bio-molecule of interest. Biosensors task is to identify presence of targeted molecule and supply result into a measurable signal. Comparing with conventional biological equipments, micro scale biosensors are very fast, reliable and price effective. Microelectromechanical systems (MEMS)/nanoelectromechanical systems are used for designing of such biosensors, which might be utilized in several biological applications. Sensing mechanism of biosensor is varied with the application. This paper is focused on detection of bio-molecule using microcantilever beam. Biosensor has shown here uses piezo-resistive method for detection of targeted bio-molecule. This Bio-MEMS device is designed and simulated using coventorware software. This biosensor wants to identify a presence of T.B. in a very suspected patient. For detection of primary stage of tuberculosis (ESAT-6), specific antibodies need to immobilize on top of microcantilever. Once patient sample (consist of ESAT-6) is placed on functionalized cantilever surface, biochemical reaction happen between tuberculosis antigens ESAT-6 and antibodies. Adsorption of antigens will increase mass working on cantilever and results in bending of microcantilever. This deflection shows the presence of tuberculosis within the patient sample.

Analytical and FEA based analysis of homopolar poly-phase transverse flux machine

Abstract: This paper proposes a novel topology for a transverse flux machine (TFM) to address the three major issues associated with conventional TFM, namely: multi-stack poly-phase TFM, low power factor and difficulty in construction. The proposed machine has homopolar main field flux set by the rotor and a hetero-polar winding arrangement on the stator. Design equations and equivalent magnetic circuit model of the proposed topology are presented in this paper. The machine is analyzed both by using equivalent magnetic circuit approach and three dimensional finite element analysis (FEA). Results obtained by both the methods are compared.

Architectural Considerations for Next Generation IoT Processors

Abstract: Currently, the growth of the first generation Internet of Things (IoT) system for low-end devices having less memory and infrastructure is challenged due to the lack of engineering support in terms of architecture, technology, hardware, privacy, security, and business. This paper discusses system engineering issues relevant in IoT processors and builds a case for exploring rough set as an approximate computing technique in next generation IoT hardware. The proposed approach has a potential of dealing with inconsistencies arising at layers in hardware infrastructure for IoT applications with a dominance at cloud and fog processing. The authors bring out a research direction in IoT as an engineering discipline with an emphasis on the impact of processor hardware extension.

Effect of Burnishing Parameters on Surface Finish

Abstract: Burnishing is cold working process in which hard balls are pressed against the surface, resulting in improved surface finish. The surface gets compressed and then plasticized. This is a highly finishing process which is becoming more popular. Surface quality of the product improves its aesthetic appearance. The product made up of aluminum material is subjected to burnishing process during which kerosene is used as a lubricant. In this study factors affecting burnishing process such as burnishing force, speed, feed, work piece diameter and ball diameter are considered as input parameters while surface finish is considered as an output parameter In this study, experiments are designed using 25 factorial design in order to analyze the relationship between input and output parameters. The ANOVA technique and F-test are used for further analysis.
