In this paper, an automatic speech recognition (ASR) system under ubiquitous environment is proposed, which is successfully implemented in a personalized voice command system under vehicle and living room environment. The proposed ASR system describes a novel scheme of separating speech sources from multi-speakers, detecting speech presence/absence by tracking the higher portion of speech power spectrum...
Parameter interval calculation has been used for fault isolation, but the verification of multi-parameter interval is difficult for multi-parameter fault. To check a multi-parameter interval whether contains the parameter vector value of the faulty system, the vertex algorithm can be used when the isotonic condition is satisfied, and then the calculation is greatly simplified. For the systems which...
For the current inefficient use of distribution network equipment and the lack of effective evaluation means, a set of comprehensive evaluation index system is built, which could accurately evaluate utilization level of equipment and find weakness. First, use fish bone diagram to find out influencing factors of distribution network equipment utilization; then build evaluation index system of distribution...
The proposed research will focus on developing a novel approach to solve Software Service Evolution problems in Computing Clouds. The approach will support dynamic evolution of the software service in clouds via a set of discovered evolution patterns. An initial survey informed us that such an approach does not exist yet and is in urgent need. Pattern will be categorised into five groups in order...
Many key problems of the control system can be effectively reflected by the inverted pendulum system, such as the problem of nonlinear system, robustness, servo system, stabilization and tracking, etc. Any control problem with whose center is above and fulcrum is blow can be approximate into an inverted pendulum model, so the study of inverted pendulum has important practical significance. In this...
SaaS (Software as a Service) and cloud computing are two emerging concepts. This article will combine them together and conduct a comprehensive research, SaaS can solve problems such as insufficient hardware and bandwidth by using cloud computing. In the mean time, cloud computing can make its own powerful integrated resources perform more adequately through the SaaS model, thus all structure the...
