Since conventional silicon metal-oxide-semiconductor field-effect transistor (MOSFET) is approaching its scaling limit, novel devices structures are being explored lately. The scaling of the technology to dimensions below ~45 nm, where short channel effects start to become significant, ... Read More
The use of optical sensors in the industry is still growing. A transmission of signal from the sensors is mostly done by optical fibers. Switching the signals from optical paths may be done by using micromechanical silicon switches. The main advantage is an ability to transmit data from ... Read More
As reliability of transformer is highly dependable on high voltage condenser type bushing, there is need to design bushings with low dielectric stress to insure the large lifespan of components. It is analytically not possible to predict or analyze the stresses generated at foil edges, ... Read More
The need for high storage capacitors led to the development of polymer based capacitors. Polymers have high processability, mechanical flexibility, electrical breakdown strength and compatibility with printed circuit board (PCB) technologies; but usually have very low permittivity (K). ...

A new design of electrostatic comb drive actuator is presented in this paper by using different spring designs and with different folded beam lengths. An increased displacement of lateral comb drive actuator will subsequently be accomplished with the same actuation voltage. Stress ... Read More
The main purpose of SPIDER (Source for the Production of Ions of Deuterium Extracted from RF plasma) test facility is the investigation and optimization of a negative ion beam produced by the full size ion source for ITER NBIs (Neutral Beam Injectors). Thermal, transient, non-linear FE ... Read More
Anthropogenic mercury (Hg) emissions increase the risk of neurological and neonatal health effects in humans through fish consumption. There are several technological approaches to controlling mercury emissions from coal combustion, including the injection of a powdered mercury sorbent ... Read More
The chemisorption and absorption of CO2 bubbles have been extensively studied and modeled in literature. CO2 gas is converted into aqueous CO2, which produces OH-, HCO3- and CO32- - ions in the solution. In this study, a 3D CO2 bubble column is simulated using COMSOL Multiphysics, ... Read More
The micro machining technology that emerged in the late 1980’s can provide micron sized sensors and actuators. Actuators are used for the transformation of non- mechanical input energy into mechanical output energy. There are many types of micro- actuation mechanisms, most commonly used ... Read More
The TS (Turin Shroud) [1,2] is a fine linen fabric showing a not yet explainable [3] double body image of a scourged and crucified man stabbed on the side. Many hypotheses have been formulated without success [4] and perhaps the most reliable is one correlated to the Corona Discharge [5] ... Read More
