KURZFASSUNG In diesem Papier wird ein Vergleich der Betriebssysteme Mantis OS, cocoOS und .NET Micro Framework vorgenommen. Dabei wird der Einsatz auf Sensorknoten hinsichtlich E zienz, Sicherheit und Benutzungskomfort beleuchtet. Die jeweiligen Vorund Nachteile werden diskutiert und eine abschließende Bewertung vorgenommen. Für die optimale Wahl eines der behandelten Betriebssysteme ist der ko...

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...

micro scale gas flows has attracted significant research interest in the last two decades. in this research, the fluid flow of gases in the stepped micro-channel at a wide range of knudsen number has been analyzed with using the lattice boltzmann (mrt) method. in the model, a modified second-order slip boundary condition and a bosanquet-type effective viscosity are used to consider the velocity...

background: in human, about 25% of implanted embryos are losing 1-2 week following attachment to the uterus. a subset of this population will have three or more consecutive miscarriages which define as repeated pregnancy loss (rpl). introducing the assisted reproductive technologies (arts) made a chance for infertile couples to solve their childless problem. objective:  this study was conducted...

In this paper, we propose a traffic conditioner with promotion and fairness guarantee (TC_PFG) schemes to amend the inappropriate marking by conventional traffic conditioners. The TC_PFG is based on the Two Rate Three Color Marker (TRTCM) scheme. It can allocate appropriate bandwidth to micro-flows to reduce the unfair distribution among micro-flows and improve the utilization by allowing promo...

Thermo-elastic damping is a significant dissipation mechanism in high quality factor microstructures. In this paper, thermo-elastic damping of the in-plane vibration of fully clamped rectangular micro-plates has been studied. The governing equation of the micro-plate motion and heat conduction equation were derived. Then, The Galerkin method has been used to solve the coupled heat-displacement ...

Intelligent Tutoring Systems (ITS), also known as Intelligent E-learning Systems, is the task of providing individualized instruction, by being able to adapt to the knowledge, learning abilities and needs of each individual student. The offer of the ITS is increasing at an unrestrainable pace (Butz & Hua, 2006; Chen, 2008; Reategui & Boff, 2008; Roger, 2006). The “intelligence” in these systems...

Published studies concerning transport phenomena in micro-channel heat sinks can be divided into those concerning saturated boiling versus those focused on subcooled boiling, with the vast majority related to the former. What has been lacking is a single generalized method to tackle both boiling regimes. The primary objective of the present paper is to construct a consolidated method to predict...

THE electro-encephalographic changes following a recent head injury have been described (Williams, 1941). The observations were made upon 74 cases of head injury selected from a total of 600 because the injury had occurred less than 20 days previously. From these observations it was concluded that the electro-encephalogram (e.e.g.) accurately reflects the abnormal cerebral state caused by a rec...
