Detection performance of the smoke in the outdoor depends on weather conditions, the shadow by the movement of the sun, or illumination changes, etc. In this paper, a smoke detection system in conjunction with a robust background estimate algorithm to environment change in the outdoor in daytime is proposed. Gaussian Mixture Model (GMM) is applied as background estimation algorithm, and also, Adaboost algorithm is applied to detect the smoke for candidate region. Through the experiments with input videos obtained from a various weather conditions at the same actual road, the proposed algorithms were useful to detect smoke in the outdoor. Index Terms—GMM, adaboost, smoke detection, outdoor environments.

In this paper, we propose a method to infer the user’s behavior and situation through collected data from multi-sensor equipped with a smart clothing and it was implemented as a smartphone App. User context reasoning and behavior determine is very difficult using single sensor depending on the measured value of the sensor varies from environmental noise. So, the reasoning and the digital filter algorithms to determine user behavior reducing noise and are required. In this paper, we used EWMA, Kalman Filter and SVM processing behavior for 3-axis value as a representative value of one.

In this paper, we reinterpreted the features of a set-top box system by applying a SOA (Service Oriented Architectures) like that used in the web-based Internet and improved the way messages are handled. Our set-top box system can respond to multiple requirements.

In this paper, a new de-allocation scheme which the de-allocation channels can be used by both voice calls and packet calls is proposed. To research the possible neglect effect on voice calls for the de-allocated channels can be allocated to the new packets, a threshold of a new packet call can obtain a de-allocation channel or not is proposed and studied. The simulation results show that the new scheme can achieve excellent performance and it is really necessary to let the new packets use the de-allocated channels, when the threshold thetas=2/3 of our scheme in this paper, the blocking probability of voice calls and the mean packet transmission time have nearly no degradation, while the blocking probability of packet calls is decreased evidently and the mean channel utilization is improved significantly.
