In this paper, we propose an Error Tolerant Dual-Hydrophone Localization method, i.e., ET-DHL, in underwater sensor networks (USNs). To reduce the impact of the node uncertainty, measurement uncertainty, poor link quality and long latency for underwater localization problem, ET-DHL adds bit-level probability to process the binary sequence. Different from our previous work PCM, each dual-hydrophone...
Missing values are an unavoidable problem in a number of real world applications and how to impute these missing values has become a challenging issue in industrial production. Even though there are some popular imputation methods proposed, these methods perform poorly in the estimation of missing values in the trash pickup logistics management system (TPLMS). The problem of missing values in the...
Moving object detection is often one of the most basic and important stages in computer vision applications. In this paper, a novel background model is proposed to extract moving foreground objects from videos that may contain different kinds of disturbance such as illumination changes, camera parameter variations, noises and dynamic backgrounds, etc. For each frame, a local frequency response map...
Since the power integrity problem has become one of the critical issues that limit the design performance, it is essential to obtain the supply current waveforms at early design stages to make efficient reduction of the supply noise. Therefore, a high-level macro current model is proposed in for logic blocks to provide quick current waveform estimation at RTL. However, due to the different arrival...
We design and implement a Job Management System for improving automation level of job execution process in network-based digital multimedia content production. Jobs are automatically parallelized and executed on a large number of execution machines. Our implementation of the Job Management System has two novel aspects. One aspect is using a feedback mechanism in execution time estimation base on Extreme...
Fire source localization is an important direction in the research area of fire detection. For application researches of fire source localization in fire nonage, a method of fire source localization and its algorithm are presented in the paper, via. transforming the task of fire source localization to the orientation detection of gas signal source beneath the certain conditions, in which a mode of...
For application researches of the detection for the gas signal source, a method for orientation estimation of the gas signal source in the two-dimensional space and its algorithm are presented in the paper. In the method, a mode of dual-line gas sensor array is applied to sample the signals of the gas concentration in real time, and the time delay estimation, an approach of the signal processing,...
