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

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

CASE ANALYSIS FUJI Vs KODAK
Introduction to the Case
Kodak’s revenues were down from $15.97 bn in 1996 to $14.36 bn in 1997 and net earnings fell from $1.29 bn to just $5 mn
More than 5 percent points decline in the US marketshare (from 80.1% to 74.7%)
Analysts felt that Kodak had underestimated its competitors especially Fuji Photo Film
Fuji entered the market in the mid- 1990s with 10% marketshare and increased it to 17% in 1990s
Aggressive marketing by Fuji brought down prices significantly
Contd ....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
