In this work we propose an efficient parallel approach of Hidden Markov Model classification based on Cell Broadband Engine (Cell/B.E.) architecture. The Cell/B.E. technology offers us the possibility of developing two level parallelization algorithms due to the hybrid architecture feature of this kind of processors. Based on this concept, we developed and analyzed two different techniques of parallelization...
The paper presents a relationship among three important concepts: Power quality, Energy efficiency and Performance of the company operating in energy field. In most of cases, the improvement of Power quality determines an increase of the Energy efficiency and, of course, the increasing of the performance of the company. The balancing between two of them, could give us the optimum solution to act in...
In this paper we will try to present a new technique of navigation in a virtual environment using dynamic gestures performed with arms and we made a performance analysis of the navigation system. System evaluation has been made using following performance parameters: accuracy, precision and sensitivity of gesture recognition.
In this paper we present a parallel approach for radiation propagation simulation using Monte Carlo technique. Our work focuses on developing techniques of parallelization and optimization of Monte Carlo simulation algorithms specific to the CBEA-based clusters. The results of the first attempts of developing a parallel Monte Carlo simulation for photon propagation are presented in this paper. These...
The supercomputers built with processors based on CBEA architecture are relatively new and there are fewer applications optimized for this type of system. In this article, we propose to use computing resources provided by a CBEA-based cluster by parallelization and optimization of an algorithm for classification of a large dataset. In order to analyze the proposed methods of parallelization, the algorithm...
Emotion recognition has become a “must have” for all system that want to inspire user's confidence and to interact in a friendly and familiar way. In this paper we propose an improved CBST (Computer Based Speech Therapy System) architecture by using multimodal (i.e. paralanguage, visual, and physiological parameters) emotion recognition techniques. Most research on emotion recognition using speech...
The analysis of large data volumes needs high computational ability. In order to accomplish this analysis in reasonable time, computer systems based upon multicore processors should be used. A method of implementing an algorithm of hierarchical data clustering to a computer system based on Cell BE processor is presented in this paper. The algorithm illustrated here was implemented in two versions:...
Improving the Power Quality and the Energy Efficiency are the strategic goals of the Electricity Distribution and Supply Company — ELECTRICA. In Romania, there are eight subsidiaries as a regional part of the mother company — ELECTRICA. Each of the subsidiaries has about one-milion electricity customers. Generally speaking, Power Quality has an important influence on the market shares of the company...
