In this paper, a Finite Element (FE) and scaled-up experimental modal analysis are employed to estimate the natural frequencies of individual spherical and ellipsoidal cells. It is apparent that the mechanical properties of the living cells and particularly the natural frequencies might ... En savoir plus
Acoustic metamaterials are structured materials of negative mass density or negative bulk-modulus or both of them. Materials are tailored in sub-wavelength dimensions so as to get these negative properties. This paper compares the result of an experimental investigation of acoustic ... En savoir plus
Cardiovascular disease has become a major healthcare problem. To tackle this along with bypass surgery, the use of the cardiovascular stent is considered promising and effective. In this study, we aim to find the effectiveness of stent deployments and their influence on haemodynamics ... En savoir plus
Ar/H2 discharges are frequently used in various industrial applications, such as etching processes, surface treatment, and film deposition. In the discharges, the active species, such as ions and hydrogen atoms, are responsible for surface reactions, which could be considered as the ... En savoir plus
The Gas Electron Multiplier (GEM) technology has been proven to tolerate rate larger than 50 MHz/cm2 without noticeable aging and to provide the sub millimeter resolution on working chambers up to 45x45 cm2. A new GEM based tracker is under development for the Hall A upgrade at ... En savoir plus
In this study the flow through a tube filled with highly porous aluminium foam of three different pore sizes is analysed using COMSOL Multiphysics® CFD Module and compared to experimentally determined pressure drop data. Analyzing the flow through an array of pores allow the deduction of ... En savoir plus
Self-heating is a problem to consider for Ultrasound Imaging probes. Since the probe is in contact with the skin, it’s necessary to find a solution to lower the front face temperature in order to avoid patient discomfort, even at the most demanding operating condition. One solution ... En savoir plus
Several undergraduate programs include the “Heat transfer” subject and, in our experience, it is hard for the students to grasp the concepts that are presented in the course. With this in mind, we designed and constructed an apparatus for the experimentation of heat transfer in a short ... En savoir plus
In the Collaborative Research Centre 692 at TU Chemnitz several academic institutions work on aluminum matrix composites (AMCs). These materials consist of an aluminum matrix, which is reinforced by SiC or Al2O3 particles with dimensions less or equal 1 µm. One main task is finishing ... En savoir plus
This paper describes the design and characterization of an 8 slots resonant cavity Magnetron, which undergoes thermal-structural effects due to cathode heating. The proposed study involves Thermal Stress, Eigen-frequency and Particle Tracing analysis based on COMSOL Multiphysics®. ... En savoir plus
