Solar systems are used around the world, especially in sunny and dry regions, to convert radiation energy from the sun into electricity or heat. Soiling, as dust deposition onto surfaces is commonly called, hinders this conversion of the solar energy by blocking of the incidenting light. ... 詳細を見る

In the humanitarian demining setting, it is crucial to detect landmines with reliable sensing performance. As Nuclear Quadrupole Resonance (NQR) is an effective method for detecting explosive materials, our group is currently developing the world’s first low-cost system for anti-vehicle ... 詳細を見る

Water disinfection using UV light is a well-known technology. Conventionally, mercury based cylindrical lamps are used, however, recently LED based UV lamps have emerged on a commercial scale. These devices hold several advantages compared to the conventional lamps, e.g. being mercury ... 詳細を見る

Indoor thermal comfort has become a hot topic as energy saving raises the public attention. Accurate thermal flow prediction in an indoor environment and its influence on human provides a critical background to the development of comfort-providing yet energy-saving solutions. This study ... 詳細を見る

Modeling the acoustic output of wind turbines presents extreme simulation challenge due to the geometry of rotors and towers requiring very large mesh size with large volumes of empty space between blades. In this paper, the structural-acoustic finite element models that were previously ... 詳細を見る

Introduction In this study, we investigate the damping mechanisms of particle resonances in acoustofluidic systems using the finite element framework of COMSOLTM. In the field of acoustic micro-manipulation, pressure waves are used for the contactless handling of micro-meter sized ... 詳細を見る

An important yet rarely explored problem in room acoustics is how to correlate the decay times of modal resonances to the acoustic properties of the boundaries (walls). The room response is often described by reverberation times, but the reverberation model breaks down at low frequency, ... 詳細を見る

The use of cardiac rhythm management (CRM) devices is the first choice of therapy for the treatment of slow heart rate (bradycardia) and abnormal heart rate (tachycardia). A Pacemaker (PM) is a device implantable inside the body able to deliver low voltage electrical signals to the ... 詳細を見る

The free-radical photo-polymerization of thermoset polymers is an essential part in additive manufacturing, in particular for the Stereolithography (SLA) printing technique. A better understanding of the photo-polymerization and its relation to the process is required to improve the ... 詳細を見る

Heat transfer from human body to the environment through clothing layer depends on many factors such as environmental conditions, thermal properties of clothing and size and shape of enclosed air layers (air layers between body surface and clothing). In clothing science, most numerical ... 詳細を見る
