Previous work in leakage current reduction for digital circuits can be divided into two main categories: static design-time selection of slow, low-leakage transistors for non-critical paths and dynamic deactivation of fast leaky transistors on critical paths. Leakage power is dominated by critical paths, and hence dynamic deactivation of fast transistors could potentially yield large savings. W...

The rising availability of multiprocessing platforms has increased the importance of providing programming models that allow users to express parallelism simply, portably, and efficiently. One popular way to write parallel programs is to use threads for concurrent sections of code. User-level threads packages allow programmers to implement multithreaded programs in which thread creation, thread...

aisi 304l austenitic stainless steel with different grain sizes of 0.5 -12 μm was obtained through the martensiticprocess. corrosion behavior of different samples was investigated in a 0.5m hcl solution using open circuitpotential, potentiodynamic polarization and electrochemical impedance spectroscopy tests. also, the correlationbetween the grain size and pitting corrosion resistance was asses...

Object-oriented languages are often promoted as encouraging the production of flexible, reusable software. Unfortunately, experience suggests that although individual classes may be reusable, large class libraries seem to lack flexibility in the face of circumstances unforeseen by the designer. This paper explores the problems associated with flexibility and reuse in large libraries, and shows ...

One of the issues in creating any search technique is balancing the need for diverse exploration with the desire for efficient focusing. This paper explores a genetic algorithm (GA) architecture which is more resilient to local optima than other recently introduced GA models. and which provides the ability to focus search quickly. The GA uses a fine-grain parallel architecture to simulate evolu...

It has long been thought that coarse-grain parallelism is much more efficient than fine-grain parallelism due to the overhead of process (thread) creation, context switching, and synchronization. On the other hand, there are several advantages to fine-grain parallelism: architecture independence, ease of programming, ease of use as a target for code generation, and load-balancing potential. Thi...

This paper describes a GA for job shop scheduling problems. Using the Giffler and Thompson algorithm, we created two new operators, THX crossover and mutation, which better transmit temporal relationships in the schedule. The approach produced excellent results on standard benchmark job shop scheduling problems. We further tested many models and scales of parallel GAs in the context of job shop...

Our aim is to development of the inspection system of wooden chopsticks, and in this paper, we develop the prototype for high-class disposable wooden chopsticks by computer vision technology. We propose a method of inspecting the four items of fine grain sample, coarse grain sample, unpeeled sample, and defective sample. Moreover, we addressed not only the proposal of the algorithm but developm...
