Crowdsourcing is rising as a new framework that enables human workers to solve tasks in the physical world. With spatial crowdsourcing(SC), a major challenge is to assign reliable workers to nearby tasks. The goal of such task assignment process is to maximize the task completion in the face of uncertainty. Two modes of task assignment have been proposed by Kazemi and Shahabi: worker select task(WST)...
Rescue and salvage works are often carried out under the sea in harsh conditions. The position and attitude of under platforms may change at any time by ocean currents, thus produces great difficulties for underwater search and fixed-point rescue. This paper aims to realize the efficient control of underwater platform attitude and effectively improve the operation efficiency of underwater platforms...
Dempster-Shafer Theory has been extensively employed in the field of information fusion due to its impressive capability to cope with uncertain information. But when it deals with completely conflictive evidences or highly conflictive evidences, the phenomenon of counter intuition will occur. In this paper, shortcomings of the commonly accepted measure of conflict are analyzed and to avoid the wrong...
The Internet of Things (IoT) technology, based on the wireless sensor network, is developing rapidly and permeating into agriculture including livestock farming. Our research focuses on the problem that current industrial IoT system for livestock farming is tightly coupled, hard to expand, and with poor network performance. In this paper we proposed an integrated framework of smart livestock farming...
The outcome of smartphone greatly changes the life of people. It is of importance to understand the usage pattern of varieties of applications in social life. Many researches have centered on this topic through statistics of the log files. However, most of them treat the location of the user as an element of the statistical result but not the cause for the usage pattern. In this paper, by analyzing...
There are many types of liquid level measurement instrumentations in modern technology, including the multiple-liquid level measurement. However, there are some practical considerations that make them unfit to use in car washer tanks. They are often too expensive, too cumbersome, too awkward and unsuitable in tanks. Only a few of them are suitable enough for the technology to widely benefit their...
Nowadays, the Internet of Things (IoT) is receiving more attention in commercial and academic research, especially about its security property. However, current protocols cannot satisfy the requirement of various IoT applications and introduce some problems. There are three typical problems: traditional public key infrastructure (PKI) apply in IoT will incur great overhead, wireless sensor network...
