The novel characteristics of a new lateral PNM Schottky collector bipolar transistor (SCBT) on silicon-on-insulator (SOI) are explored using two-dimensional (2-D) simulation. The collector-base junction of the proposed lateral PNM transistor consists of a Schottky junction between n-base (N) and metal (M). The characteristics of this structure are compared with that of lateral PNP transistors o...

Simulation for the smooth muscle layer of blood vessel plays a key role in tubular tissue engineering. However, fabrication of biocompatible tube with defined inner nano/micro-structure remains a challenge. Here, we show that a biocompatible polymer tube from poly(l-lactide) (PLLA) and polydimethylsiloxane (PDMS) can be prepared by using electrospinning technique, with assistance of rotating co...

In this paper, the effects of residual charges on nanofiber alignment in a gap method are studied and presented. The gap method was presented by Li and Xia (2003 Nano Lett. 3 1167); in it, a gap is introduced into a traditional collector. Due to the non-perfect conductivity of electrospun nanofibers, they carry residual charges after deposition across the gap. These residual charges will intera...

The material dependence of hot electron magnetotransport in a spin-valve transistor has been theoretically explored. We calculate the parallel and antiparallel collector current changing the types and relative spin orientation of the ferromagnetic layers. The magnetocurrent has been presented as well. In this calculations, spin dependent self energy effect of hot electron in ferromagnetic mater...

This paper describes the design and the evaluation of Complementary Garbage Collector that is a fundamental algorithm for the parallel and incremental garbage collector. Our algorithm is a combination of two types of fundamental algorithms, incremental update and snapshot-at-beginning, which are complementary to each other. The algorithm has the advantages of both types: great e ciency of the g...

-We propose an improved method for eye-feature extraction, descriptions, and tracking using deformable templates. Some existing algorithms are exploited to locate the initial position of eye features and then deformable templates are used for extracting and describing the eye features. Rather than using original energy minimization for matching the templates, the region-based approach is propos...

Garbage collectors are an important part of many modern language runtimes. Essentially all tools for developing and debugging programs using garbage collection assume the correctness of the collector, and therefore provide no means for detecting garbage collector errors. As a result it is especially important that garbage collector implementations be free of errors. This goal is even more chall...

As the fossil fuels are depleting continuously, we know that solar energy harvesting is a significant potential area for new research dimensions. Sun provides us about 1.9 x 10 8 TWh/yr on the land, of which 1.3 x 10 5 TWh]/yr energy is used. In order to make much use of solar energy on the earth, solar energy harvesting into more usable form (e.g. heat or electricity) by using solar energy col...

As real-time systems become more complex, the need for more sophisticated runtime kernel features arises. One such feature that substantially lessens the burden of the programmer is automatic memory management, or garbage collection. However, incorporating garbage collection in a real-time kernel is not an easy task. One needs to guarantee, not only that sufficient memory will be reclaimed in o...

We describe an efficient and fault-tolerant algorithm for distributed cyclic garbage collection. The algorithm imposes few requirements on the local machines and allows for flexibility in the choice of local collector and distributed acyclic garbage collector to use with it. We have emphasized reducing the number and size of network messages without sacrificing the promptness of collection thro...
