Three efficient alternatives to the model in COMSOL’s thermoacoustics interface are presented. The higher efficiency of these models are explained from theory and are demonstrated by means of two examples. Mehr lesen
Electromagnetic sounding measurements utilize magnetic induction to constrain the interior geophysical properties of planetary bodies. Under some conditions, the Earth’s moon can be approximated by the response of a conducting sphere in a vacuum. Transient magnetic fields originating ... Mehr lesen
Microarrays are extensively used in modern biology as tools of multiplexed, high throughput analysis to study thousands of genes and their expression inside cells at once [1]. The basic principle of a microarray is quantitative detection of fluorophore tagged DNA. Use of this method ... Mehr lesen
The aim of this paper is to determine the location of the “sweet spot” for a selected cricket bat commonly used in the sport. Knowledge of the “sweet spot” is important in delivering a shot that utilizes the optimal zone of the bat that corresponds to the maximum power of the stroke. A ... Mehr lesen
In this paper an Electromagnetic Solenoid Actuator (EMVA) consisting of an upper and lower electromagnet, a linear moving armature and two preloaded springs is considered as a potential approach in Variable Valve Actuation (VVA) systems for internal combustion engines. The analysis of ... Mehr lesen
Objective of this contribution is to present a procedure for evaluating second order drift forces on floating bodies, often the most important loading component for mooring design, in case of high waves propagating in relatively shallow water depths. The non linearity associated to this ... Mehr lesen
This work describes the design and optimization of three prototypes of microelectromechanical systems (MEMS) capacitive accelerometer-based middle ear microphone. The microphone is intended for middle ear hearing aids as well as future fully implantable cochlear prosthesis. The analysis ... Mehr lesen
Manual manufacturing of inlay fixed partial denture frameworks by metal casting can take hours of dental practitioners work time. This paper introduces 3-D simulations of premanufactured inlay fixed partial denture framework assembled from laser cut sheet metal parts. The study gives a ... Mehr lesen
Introduction: The dual electromagnet configuration of Active Magnetic Levitation system (AML) where the electromagnets are locate opposite to each other, constitutes and single axis of the Active Magnetic Bearing. The same configuration can be used to test the single electromagnet AML ... Mehr lesen
A 2D numerical model for determination of sound reduction index is set up in this work. Results are in good agreement in middle and high frequency range when using solid structure approximation. Results are compared with experiment. Mehr lesen
