This paper presents the formulation, validation, and application of a spectral/hp algorithm for numerical solution of the Navier–Stokes and heat/scalar transport equations in arbitrarily moving complex geometries. The new spectral element algorithm is based on the arbitrary Lagrangian Eulerian formulation and utilizes modal expansion of Jacobi polynomials in mixed triangular and quadrilateral e...

A high-pressure electro-osmotic (EO) micro-pump fabricated by a sol–gel process is shown to be potentially effective as a fluid-driving unit on chip-scale analytical systems. A silica monolithic matrix with a morphology of micron-scaled through pores was synthesized within the 100 m inner diameter (i.d.) fused-silica capillary of the micro-pump. The monolith bonds directly with the capillary wa...

Knowledge management is a business model that embraces knowledge as an organizational asset to drive sustainable business advantage. Nowadays the leaders know that they are moving towards knowledge era very fast and they should align all activities in a way that knowledge management facilitates the competition in a better way. Developed countries also try to apply knowledge policies all over th...

Robotics was successfully applied to the medical field which led to a new scope with vast areas of research; specially, robotics with dental application is relatively an untraveled area to explore. Access opening, bio mechanical preparation and obturation are the three vital steps in endodontic treatment. This procedure is time consuming and completely relies on the clinician’s mastering skills...

Robots moving in a crowd occasionally reach situations where they need to decide whether to give way to a human or not, a situation we call a micro-conflict and model with a two player game. We collect data from a robot controlled by a human operator and use three different supervised learning algorithms (random forest, SVM and neuroevolution) to create a decision maker module which imitates th...

AIMS Transmission routes of noroviruses, leading aetiological agents of acute gastroenteritis, are rarely verified when outbreaks occur. Because the destination of norovirus particles being firmly captured by micro-organisms could be totally different from that of those particles moving freely, micro-organisms with natural affinity ligands such as virus-binding proteins would affect the fate of...

The Micro-Mouse is an autonomous robot that is capable of moving about within a maze and finding its way to the center in the shortest possible amount of time. The complete robotic system is a synthesis of mechanical design, motor control, sensory input systems, electrical design and software development system.

In this paper, we consider moving target detection and ranging for indoor sensing applications in urban environments. A simple method is used to determine the unambiguous range of an indoor moving target using dual frequency continuous wave (CW) radars. The dual-frequency radar employs two different carrier frequencies and simultaneously measures the phase change with respect to time, for each ...

The technical progress in key technologies as microelectronics, telecommunication and micro-electro-mechanical systems (MEMS) proceeds rapidly. Classical education at universities has to be accomplished by additional learning activities to fulfill the requirements of life-long learning in companies and research institutions. The Internet techniques offer the technical basis to provide engineers...
