Abstract
The proper design and simulation of modern electronic microsystems oriented towards environment monitoring requires accurate models of various ambient sensors. In particular, this paper presents a comprehensive model of an ion sensitive field effect transistor (ISFET). The model can be employed straightforwardly for simulations at device, circuit or system level. First, the model was validated with electrical measurements a ....etc

Abstract:
The ELIICA is a revelation of a concept car made in Japan that is totally electric. The ELIICA short form for Electric Lithium Ion CAr was developed and created by Prof. Hiroshi Shimizu of Keio University, Tokyo. The ELIICA is powered by lithium ion batteries and uses eight 60kw in-wheel drive motors to provide the equivalent of 800hp. The in-wheel drive eliminates the need for the power transmission devices connecting the engine and the wheels that are necessary in conventional cars. Because all the wheels are d ....etc

Ion Beam Machining
Ion source
The Ion Source has arrays of permanent magnets to produce a multi-cusp magnetic field in regions remote from the plasma grid and the RF antenna.
The field confines the plasma by lengthening the path of ionizing electrons and reducing their drift to the walls.
Plasma sources generate plasmas.
Excitation of plasma requires partial ionization of neutral atoms and/or molecules of a medium.
There are several ways to cause ionization: c ....etc

Modern radiation therapy techniques, such as stereotactic radiotherapy and tomotherapy, deliver the total treatment dose to the patient using many small fields. This helps to construct a dose distribution which delivers a high dose to the tumour, while minimizing the dose to normal tissue. When considering a single small field, the dose resulting from that small field is usually reported as a relative dose factor (RDF). The RDF is the percentage of dose in a small field as compared to a large reference field. Task group report #51 from the Amer ....etc

ISFET is an ion-sensitive field-effect transistor used to measure ion concentrations in solution and is a new type of miniaturised semiconductor chemical sensor. It is based on the structure of the metal-insulator-semi-conductor field-effect transistor (MISFET) in which a metal gate is replaced by an ion selective membrane, an electrolyte and a reference electrode here when the ion concentration (such as pH) changes, the current through the transistor will change accordingly. Here, the solution is used as the gate electrode. A voltage between s ....etc

Ion Beams Machining (IBM) is an important nonconventional manufacturing technology (Hellborg et al. 2009), which uses a stream of accelerated ions by electrical means in a vacuum to remove, add, or modify atoms on the surface of the object. IBM can be classified into two main categories, that is, Large-area Ion Beam Machining (LIBM) technology and Focused Ion Beam Machining (FIBM) technology ....etc
