Service computing is a popular development paradigm in information technology. The functional properties of Web services assure correct functionality of cloud applications, while the nonfunctional properties such as reliability might significantly influence the user-perceived availability evaluation. Reliability rankings provide valuable information for making optimal cloud service selection from...
Recently, there are many improvements in Internet of Things (IOT). Through the recombination and optimization, the real-world devices can provide their functionality as web services in IOT. However, it is very difficult to cost-effectively access to the Internet of Things due to the environmental changes. In this paper, firstly, a Petri net-based model for service composition in IOT is proposed, which...
Phase change memory (PCM) has many advantages over the traditional DRAM technology, hence it becomes a promising candidate for main memory. Multi-level cell (MLC) PCM has the benefits of higher capacity and lower cost-per-bit due to store multiple bits in a single cell. However, MLC PCM employs an iterative write scheme, which is precise, reliable but slow, incurring adverse impact on the system performance...
Phase change memory (PCM) is a promising nonvolatile memory technology developed as a possible DRAM replacement. Although it offers the read latency close to that of DRAM, PCM generally suffers from the long write latency. Long write request may block the read requests on the critical path of cache/memory access, incurring adverse impact on the system performance. Besides, the write performance of...
Phase change memory (PCM) has emerged as a mostly promising non-volatile memory. Multi-level Cell (MLC) PCM that stores multiple bits in a single cell, has the benefits of increasing capacity and lower cost-per-bit. However, as feature size scales down, prior work reports that low frequency noise and random telegraph noise would greatly jeopardize the reliability of MLC PCM. In this paper, we firstly...
This paper discussed specific applications of reliability, maintenance, protection, testability, security and environment adaption designs based on ATE automatic test system, which provide effective technical references for ATE researchers to choose reasonable design solutions and create general automatic test equipment with high efficiency and practicality.
As a novel service robot, the automatic cooking robot (ACR) has been attracting many people's attentions. But the existing products still have some disadvantages, especially the quick-return mechanism used as the main mechanism to turn over the pan. There are always large vibrations and noises accompanying with the motions of the quick-return turning-over mechanism. And its stability and reliability...
