The Transistor, A Semi-Conductor Triode

Automotive semi-conductor trend & challenges

The automotive electronics has been introduced with multiple waves over the time: powertrain, safety & vehicle dynamic, body & convenience, telematics. The future is already knocking at the door and revolutionary systems are currently developed: X-by-wire, E-safety, Hybrid vehicle. The increasing requirements for fuel economy, safety, emission reduction, and onboard diagnosis push the automotiv...

Smart, Biocompatible Semi-conductor Nanocrystal Constructs

Orbital ordering in the two - dimensional ferromagnetic semi - conductor

PACS. 71.20.-b – Electron density of states and band structure of crystalline solids. PACS. 71.20.Be – Transition metals and alloys. Abstract. – We present the results of electronic structure calculations for the two-dimensional ferromagnet Rb2CrCl4. They are obtained by the augmented spherical wave method as based on density functional theory and the local density approximation. In agreement w...

Verification of the Accuracy of the Delivered Dose in Pelvic and Breast Cancer Radiotherapy by in-vivo Semi-Conductor Dosimetry

Introduction: Delivering maximum dose to tumor and minimum dose to normal tissues is the most important goal in radiotherapy. According to ICRU, the maximum acceptable uncertainty in the delivered dose compared to the prescribed dose should be lower than 5%, and this is because of the relationship between absorbed dose, tumor control and normal tissue damage. Absorbed dose accuracy is investiga...

On the characteristic cycle of a constructible sheaf and the semi-continuity of the Swan conductor

We define the characteristic cycle of an étale sheaf as a cycle on the cotangent bundle of a smooth variety in positive characteristic assuming the existence of a singular support. We prove a formula à la Milnor for the total dimension of the space of vanishing cycles and an index formula computing the Euler-Poincaré characteristic. An essential ingredient of the construction and the proof is a...
