In this paper two MEMS capacitive pressure sensor of two diffident geometries are designed for measurement of absolute pressure. Both of these sensors are designed as parallel plates where one is movable and the other is fixed. The only difference with common parallel plate structure is that one of the movable plates is supported by four anchors with respect to the fixed plate. Here we have con...

To reduce the working resistance and soil adhesion in process of tillage or engineering construction, this paper takes bulldozing plate as research object cutting angle directrix form Soil engaging surface design variables, designs 15 groups models for bin experiments. The test results show that compared with conventional circular plate, horizontal bionic 50 degrees, 55 60 degrees angles is red...

Cesium chloride centrifugation of DNA extracted from cells of blood strain Trypanosoma lewisi revealed a main band, rho = 1.707, a light satellite, rho = 1.699, and a heavy satellite, rho = 1.721. Culture strain T. lewisi DNA comprised only a main band, rho = 1.711, and a light satellite, rho = 1.699. DNA isolated from DNase-treated kinetoplast fractions of both the blood and culture strains co...

Introduction: Micro-perforated absorbents are one of the structures that are widely used nowadays. The sound absorption mechanism is performed by viscous energy losses in the cavities on the plate. In this study, the acoustic properties of non-flat perforated panels in oblique angle was investigated in numerical method. Material and Methods: This paper examined the effect of the surface shape ...

Experiments were performed tribo-tester with facility simulating A ball-on-plate model in reciprocating motion dry, oil-lubricated, water-lubricated conditions. T...

The modelling, simulation, fabrication and testing of a microchannel cooling plate are described in this article. The cooling component is to be used in microelectronic packaging applications. The nickelbased micro-channel cooling plate is fabricated on a glass substrate using a two-layer electroforming process borrowed from UV-LIGA. Forced convection of air or liquid is scheduled for this micr...

The MET95 strain of a lentogenic Newcastle disease virus (NDV) isolated from a broiler in Japan, showed unique hemagglutination (HA) activity. The MET95 strain failed to show HA when examined by rapid glass plate method although they showed HA titer of 1:1,024 by micro-plate method. This unique HA was also observed after the MET95 strain was passaged ten times in chickens. The failure of HA by ...

Abstract Micro-hot embossing (micro-HE) of polymeric materials creates exact micro/nanoscale designs. Micro-HE processes include plate-to-plate (P2P), roll-to-roll (R2R), and roll-to-plate (R2P). is preferred for large-scale production micro-patterns on polymer substrates. However, the lack simulation models optimization component design prevents broad use this technology. As size micro pattern...

This study develops a continuous model to analyze the ‘pull-in’ effect in the circular micro-plates used in capacitive-type micro-electro-mechanical systems (MEMS) sensors, actuators and microphones. In developing the model, the governing equation of motion of the deformed plate is established in the form of a partial different equation (PDE) which is then decomposed using the Galerkin method t...

The determination of bending moments, tWlstmg moments, and shearing forces in a thin circular elastic plate subjected to symmetrical bending is a problem which is often encountered in the design and analysis of structural elements or systems. This study deals.,with the solution of this problem for a thin circular elastic plate supported at points equally spaced along a concentric support c ircl...
