The “last mile” problem in logistics is challenging due to its low efficiency and high cost. To address this problem, Unmanned Aerial Vehicle (UAV) delivery such as drone delivery has been proposed and widely accepted as a promising solution. However, currently most of the existing UAV delivery systems are based on Cloud Computing which cannot efficiently meet the requirements of many real‐time services...
With the rapid growth of smartphones, crowdsensing emerges as a new paradigm which takes advantage of the pervasive sensor-embedded smartphones to collect data efficiently. Auction has been widely used to design mechanisms to stimulate smartphone users to participate in the crowdsensing applications and systems. Many auction-based incentive mechanisms have been proposed for crowdsensing. However,...
Massive Internet invasions implemented through the distributed platform fabricated by rapid diffusion of malwares, has become a significant issue in network security. We argue that the notion of “Collaborative Security” is an emerging trend in resisting distributed attacks originated from malware. Therefore, this paper proposes a new architecture: CloudSEC, for composing collaborative security-related...
Abstract-To study the effect of Xiaoyaosan on changes of behaviors (the open field test, elevated plus maze test and Y-maze test) in chronic immobilization stress (CIS) rats. Methods: 28 male Sprague-Dawley rats were randomly divided into control group, model group and Xiaoyaosan group. CIS was used to induce stress in rats of model group and Xiaoyaosan group, 3 h a day for 21 days. Xiaoyaosan was...
A 3-state Markov model is used to model some safety-critical systems, when the system states can be divided into three kinds of categories: Operating States, Failed-Safe States & Failed-Unsafe States. These models are used to estimate the system safety and security. Based on these models, a new model is built when the system fails, different defect states have different measures. For Failed-Safe...
Purchasing portfolio is a significant tool for purchasing and supply management. Although the Kraljic portfolio approach is a dominant approach in the profession, there are problems and unanswered questions with respect to measurement and strategic issues. This study describes a purchasing portfolio approach and strategic directions for steel industry. With this approach, the measurement method has...
