The ubiquitous nature of biofilms has led to a growing need to be able to detect, control, and maintain or remove them. Therefore a robust testing platform that allows for multiple analytical techniques is required to better understand their multitude of properties. The development of ... Read More
A concept of an adaptive sound absorbing material is proposed and investigated numerically using the COMSOL Multiphysics® Software suitable for the required advanced dual-scale modelling which involves solution of various problems of physics at the microscopic and macroscopic levels. A ... Read More
One of the main design questions in loudspeaker enclosures concern vibrations reduction. An ideal cabinet would be infinitely rigid, so a section of an engineer work is focused on this goal. Solutions depend by loudspeaker system audio field: Line Arrays, Automotive environments or hi ... Read More
For automotive applications, simulations are used to optimize the position and orientation of a subwoofer (loudspeaker) in a very constrained space to get the best acoustic performances. One solution is to use particular part of the BIW volume as the subwoofer enclosure. The acoustical ... Read More
Various types of FI-Relays are built in electrical protective residual current devices (RCD). They are all electromechanical assemblies that trip at appearance of residual currents (i.e. fault or earth leakage current) and consequently break main contacts of RCD. FI relays are very ... Read More
Snow can exist in a wide range of temperatures. Its behavior changes especially around its melting point. A better understanding for wet snow is essential for snow pack stability, the effect of water percolation and friction between ski and wet snow surface. Technical details about ... Read More
Microfabricated planar interdigitated electrodes can detect and analyze cells or particles giving an impedance-based characterization. This method presents several advantages: real-time detection, label-free analysis, non-invasive sensing, easiness of integration and high-throughput ... Read More
Finite element modelling of surgical transducers has been performed and is described. Ultrasonic transducers vibrating at around 25 kHz are used in orthopaedic surgery to cut bone. The high acoustic impedance of the metal blades used in these devices couples energy more efficiently to ... Read More
The growing demand for efficient transmission (1), including refurbishing of existing lines, requires technological advances beyond the actual methodologies, basically electric parameters and electromagnetic fields estimation. Some analytical models developed at CEPEL (2, 3) provide ... Read More
Duct silencers are used to reduce noise in Heating, Ventilation and Air Conditioning (HVAC) as well as noise from exhaust gas chimneys. For a duct silencer, an important trade-off has to be made between the achieved noise reduction and the pressure drop. Using an example model, we will ... Read More
