This study proposes a node-aware distributed simulation system for accelerating production simulation. To optimize simulation performance, this system proposes the performance-surveying module and the node-invoking module based on a MapReduce parallel framework to dynamically invoke valuable nodes during simulation. The performance-surveying module periodically records each node performance and ranks...
Hidden Markov Model (HMM) is a robust statistical methodology for automatic speech recognition. It has being tested in a wide range of applications. A prediction approach traditionally applied for the text compression and coding, Prediction by Partial Matching (PPM) which is a finite-context statistical modeling technique and can predict the next characters based on the context, has shown a great...
The real-world applications of ocean acoustic field computations present serious computational requirements for high performance computing technologies. At the same time, more and more engineers and researchers are using parallel processing technologies to improve computational performance using emerging parallel hardware architectures. In this paper, we introduce latest parallel computing technologies...
The paper evaluates the shielding effectiveness of a flexible metallic screen perforated with multiple square apertures. The screen shield is designed and fabricated using screen printing technique. The electromagnetic shielding performance of the screen is analyzed using empirical formulae as well as full-wave modeling. By considering the effects of measurement setup and substrate, an accurate representation...
