This paper presents an important step in developing a combined active noise- and audio system for a light jet. To prepare its installation both a wooden mock-up and a finite element model of the investigated cavity were created. Sensitivity analysis and key parameters selection were done ... En savoir plus
Many materials require functionally graded cellular microstructures whose porosity is engineered to meet specific requirements of diverse applications. It has been shown in previous work that the bubble growth rate of a polymeric foam can be influenced by the surrounding acoustic ... En savoir plus
We have developed a small environmental chamber to expose a sample to adjustable climate conditions. This climate chamber will be used as sample environment for small-angle neutron scattering (SANS) experiments. SANS is a favorable measuring method, to explore structural changes on the ...

Grating couplers are a common optical component for introducing light into chip-based photonic structures. They are used extensively for optical interconnects and optical device integration. A microfluidic diffraction grating coupled waveguide (MDGCW) biosensor applies a grating coupler ... En savoir plus
FEM (Finite Element Method) modelling software such as COMSOL Multiphysics® can be a powerful tool for modelling the behavior and response of piezoelectric materials and devices [1]. Devices based on piezoelectric crystals are particularly well suited, because the polarization magnitude ... En savoir plus
We present time-resolved methods that rely on near-infrared photons to image the optical properties and distribution of fluorescent probes in small laboratory animals. The coupled diffusion equations of excitation and fluorescence photons in highly scattering tissues were solved using ... En savoir plus
Piezoelectric energy conversion has received great attention for vibration-to-electric energy conversion over the last five years. A typical piezoelectric energy harvester is a unimorph or a bimorph cantilever located on a vibrating host structure, to generate electrical energy from base ... En savoir plus
Optical fibers that can deliver mid-infrared light in a wide wavelength range are in high demand due to their significant potentials in sensors, chemical imaging, optoelectronics and nonlinear optics applications. Semiconductors such as Ge, ZnSe and Si are good infrared-transparent ... En savoir plus
A finite element model of a total hip replacement (THR) has been developed from the approach of modal analysis. The model is capable of determining the first 15 Eigenmodes of a THR with an artificial bone model. The model was equipped with several different defects to simulate a ... En savoir plus
Recently, due to the dynamically increasing complexity of modern systems, a strong necessity appears for more systematic approaches to high quality control and process monitoring. Requirements imposed by process control in the area of spatio-temporal physical systems also called ... En savoir plus
