Background: TTFields are being investigated for treatment of brain metastasis. Although vasogenic edema is the most common type of associated cerebral edema, other forms of edema might arise within the brain due to prior treatment or other confounding effects. Therefore, we seek to ... Mehr lesen
For many decades Helium-3 (3He) and Argon gas filled detectors have been used for neutron and gamma detection. Detection requires the generation of electrons which can then be measured by electronic means. These electrons are generated either directly through gamma ionization of a gas ... Mehr lesen
Organic Thin Film Transistors are simulated for gas sensing application. The simulation is performed using COMSOL Multiphysics® simulation software's Semiconductor Module. Drift-diffusion (DD) simulation model is used in which the basic equations used are similar to those used for a ... Mehr lesen
Micro shutter array (MSA) is a programmable optical spatial filtering device fabricated by micro electro-mechanical system (MEMS) technology. It was originally developed for James Webb Space Telescope (JWST) to enable multi-object spectroscopy and operated by a moving magnet. Next ... Mehr lesen
MEMS microphones consist of a conductive backplate and a conductive flexible membrane. The backplate and the membrane are at a certain distance from each other to be interpreted as parallel plates of a capacitor. When a bias voltage is applied to the electrodes, membrane deflection ... Mehr lesen
Cold season thunderstorms are a threat for wind turbines in several areas of the world because the thundercloud is much closer to the earth compared to warm season thunderstorms. As a consequence, the electric field between cloud and ground is much higher during these storms, triggering ... Mehr lesen
HVDC electrodes are installed on HVDC transmission systems to provide a low resistance current return path during both monopolar and bipolar operation, using the earth and/or sea as the conductive medium. HVDC electrodes are in general less costly and have lower losses than dedicated ... Mehr lesen
This study investigates the effect of a uniform magnetic field on the lateral migration behavior of a ferrofluid droplet in a plane Poiseuille flow at arbitrary directions by means of numerical simulation. A numerical scheme called level set method in combination with the laminar two ... Mehr lesen
Due to particle interactions, magnetic particles suspended in non-magnetic fields tend to form chains, clusters or columns under magnetic fields. The non-spherical magnetic particles in the suspension show different rheological properties compared to spherical particles. In this paper, ... Mehr lesen
Disciplines such as neutron polarimetry and medical imaging depend on highly uniform magnetic fields to preserve target polarization, and have turned to "magic boxes" to reliably generate these fields. Searches for the permanent Electric Dipole Moment of the neutron (nEDM) are sensitive ... Mehr lesen
