in this paper, the stability of a functionally graded magneto-electro-elastic (fg-mee) micro-beam under actuation of electrostatic pressure is studied. for this purpose euler-bernoulli beam theory and constitutive relations for magneto-electro-elastic (mee) materials have been used. we have supposed that material properties vary exponentially along the thickness direction of the micro-beam. gov...

We report a new approach for microfluidic optical bioanalysis that is based on the electrically driven assembly of bio-components on a transparent sidewall and the optical detection of the assembled components using planar waveguides. This allows localized electrical signals for bio-assembly and optical signals for bio-detection that can easily be applied in MEMS systems. We demonstrate a BioME...

ELECTRO-OCULOGRAPHY has been established as a valuable clinical procedure for measuring indirectly the standing corneo-fundal potential, of importance in the investigation of retinal and choroidal function. Although the technique of clinical recording is not very complicated, the load of a great many records is a burden for the technical staff of an electro-diagnostic clinic. Semiautomatic reco...

Der Entwurf von Steuerungen und die Trajektorienplanung für lineare Systeme mit örtlich verteilten Parametern und konzentrierten Stelleingriffen können in gewissen Fällen auf der Basis von Potenzreihendarstellungen erfolgen. Es wird eine Methode vorgestellt, mit der diese Reihendarstellungen systematisch auch für solche partiellen Differentialgleichungen hergeleitet werden können, deren Koeffiz...

In Bangladesh, the BBC Janala project is using multimedia to give adults opportunities to learn English for economic purposes. English lessons are available on mobile phones, the web, a newspaper and a TV show. Despite the large numbers of people accessing the BBC Janala media products, there is a gendered digital divide, with much fewer women accessing the web and mobile lessons in particular....

Embedded micro processors are becoming increasingly important in medical treatments These devices are embedded in CAT scanners radiation therapy devices MRIs and are used in the control of drug production Embedded systems are becoming more sophisticated and the programs that control these system have increasing demands for precision and reliability Recently the FDA has been under increased pres...

in this research, the influence of adding micro- and nano- sized calcium carbonate powders to nylon-66 was investigated. mechanical properties of micro and nano- composites, including tensile strength, elongation, and young’s modulus, before and after ageing, were determined and analyzed. for this purpose, micro- and nano-sized caco3 particles were used as fillers to prepare micro-composites (c...
