With the rapid growth of online social media and ubiquitous Internet connectivity, social sensing has emerged as a new crowdsourcing application paradigm of collecting observations (often called claims) about the physical environment from humans or devices on their behalf. A fundamental problem in social sensing applications lies in effectively ascertaining the correctness of claims and the reliability...
A leakage detection system and a method used for detecting leakages in the wire bonding gas supply system are introduced. The leakage detection system is connected to the pipeline remotely from the gas outlet. The detection module receives flow rate signal and monitors the flow rate changes that represent the leakage in the pipeline. The importance of leakage detection in wire bonding system will...
With the rapid development of Internet technology, the mobile terminal as a carrier get more and more popular, such as smart phones, tablet PCs and other mobile wireless communicated devices, so that the MDTN (Mobile Delay Tolerant Network) has become a hot topic in the wireless sensor networks. At the same time these mobile devices have the advantages of mobility and portability, but there are some...
In this paper, we propose two novel Dynamic Active Learning (DAL) methods with the aim of ultimately reducing the costly human labelling work for subjective tasks such as speech emotion recognition. Compared to conventional Active Learning (AL) algorithms, the proposed DAL approaches employ a highly efficient adaptive query strategy that minimises the number of annotations through three advancements...
Delay Tolerant Network (DTN) shows some features like link frequent interruptions, long delays, limited resources and so on, while nodes fight each other to win the network resources in the process of communication, which can lead to network congestion in delay tolerant network. Therefore, congestion control is a key issue in delay tolerant network research. The present congestion control strategies...
Spin transfer torque-based magnetic random access memory (STT-MRAM) is considered as one of the most promising candidates for the next generation of nonvolatile memories; however, its storage density and reliability are currently uncompetitive compared with other nonvolatile memories (e.g., NAND flash). In this paper, a dual-functional memory cell structure, named DFSTT-MRAM, is proposed by stacking...
The increasing complexity of software and hardware resources and frequentative interaction among function components make fault-tolerant very challenging in pervasive computing system. In our paper, we propose a novel framework of self-adaptive fault-tolerant mechanism for pervasive computing environments. In our approach, the self-adaptive fault-tolerant mechanism is dynamically built according to...
In ubiquitous computing system, the increasing mobile and dynamic of software and hardware resources and frequentative interaction among function components make fault-tolerant design very challenging. In this paper, we propose a context and policy based self-adaptive fault-tolerant mechanism for a mobile ubiquitous computing environment such as a mobile ad hoc network. In our approach, the fault-tolerant...

A novel fault tree analysis (FTA) technique based on the Takagi and Sugeno (T–S) model is proposed in this paper. In the proposed technique, referred to as the TS-FTA, the events in the conventional FTA can be expressed in terms of fuzzy possibilities, and the gates that represent the relations among the top event and the primary events are replaced by T–S fuzzy gates derived from the T–S model. The...
