At Rensselaer Polytechnic Institute we have altered our undergraduate and graduate curricula so that we now teach transport phenomena (heat, mass, momentum, charge) in a holistic manner rather than as discrete courses. The traditional pencil-papercalculator toolset was found lacking and so we turned to FEMLAB® as a teaching tool to help enhance student understanding. In this paper, I will ...

Unter Elektrotechnikausbildung ist in diesem Papier die Hochschulausbildung und insbeson-dere die in den Fächern Allgemeine Elektrotechnik und Theoretische Elektrotechnik zu ver-stehen. Üblicherweise wird das Gebäude der Elektrotechnik auf den Erfahrungssätzen des Strömungs-, elektrostatischen und magnetischen Feldes aufgebaut. Zur Motivation und Fes-tigung des Wissens werden dann in den ...

In this paper a poly-optimization of the design of the electromechanical actuator is presented. The shape of the actuator is defined by the decision variables. The number of decision variables under consideration is up to ten but in the next step while the multi-coils system will be analyzed the number of decision variables will increase up to hundred, so the genetic algorithm has been used. The ...

Tessellated models are more and more used in several engineering fields. The need to use such models to quickly perform computer simulations related to coupled physical phenomena, implies the use of dedicated software, allowing to solve, into an integrated environment, multiphysics problems. In the present work, COMSOL Multiphysics® has been used and its ability to handle tessellated models ...

A teaching platform that could be used to help students understand concepts such as; flux linking and mutual inductance has been developed using the AC/DC Module of COMSOL Multiphysics®. This is achieved through the accurate determination of different magnetic flux density components within the proposed geometry. Furthermore, based on the structure configuration, students can use obtained ...

An undergraduate course is developed to initiate future engineers to multiphysics numerical simulation by approaching concrete cases in various fields such as: heat transfers, fluid flow, mechanics, chemistry and electrostatics. The so called “Virtual Experiments” course consists of four projects given successively to students. Each project lasts about ten hours. The major notions related to ...

Single photon emission computed tomography (SPECT) is a nuclear medicine imaging technique that uses gamma rays. It has been especially useful for bone scans, cardiac perfusion imaging, tumor scans and brain imaging. The main advantage of SPECT imaging is that it can target particular tissue receptors allowing one to focus on the imaging of the diseased tissue. In most cases Monte Carlo ...

Capacitive MEMS (Micro-Electro-Mechanical Systems) accelerometers may be directly soldered to the printed circuit board by an array of solder balls. Differences in the thermal expansion coefficients of the pertinent materials cause deformations of the accelerometer under temperature change. This may cause a relative movement of the sensing masses with respect to the sensing electrodes, resulting ...

Chaotic systems may lead to instability, extreme sensitivity and performance reduction. Therefore it is unwanted in many cases. Due to these undesirable characteristics of chaos in practical systems, it is important to recognize such a chaotic behavior. The existence of chaos has been discovered in several areas during the last 30 years. However, there is a lack of studies in relation with ...

The capillary network is a complex-interconnected structure. A single blood cell traveling from the arteriole to a venule via a capillary bed passes through, on average, 40−100 capillary segments. The cardiovascular systems responsible of delivering blood to the tissue under sufficient pressure to exchange materials. This is a two way process, at which nutrients, Oxygen, and other ...
