Cloud computing is a syncretic development result of traditional computer technology and network technology. The core idea of cloud computing is to manage and schedule huge computing resources linked by network and then provide services for users from computing resources pool. The birth and speedy development of cloud computing bring new opportunities to test field, which is the foundation of PHM-enabling...
Future robot applications will require cloud computing. Using an architecture of cloud robotics would increase performance over hardware constraints (e.g., processors, memory, and power). In this paper, we propose a control middleware for cloud robotics, which not only can receive the robots' requests and allocate the cloud resources based on the robots demand, but also can ensure the connection between...
Rule engine, which acknowledges facts and draws conclusions by repeatedly matching facts with rules, is a good way of knowledge representation and inference. However, because of its low computational efficiency and the limitation of single machine's capacity, it cannot deal well with big data. As traditional MapReduce architecture can only address this problem in certain conditions, we have made some...
Power consumption is a major obstacle for future exascale computing. We propose a low power high performance optical interconnect architecture based on AWGR with WDM wavelength routing for exascale systems. Theoretical analysis and simulation show its better performance compared with fat-tree architecture.
Cloud robotic system is a mono- or multi- robot system that profits one or more services of Cloud Computing. In a few short years, Cloud robotics as a newly emerged field has already received much research and industrial attention. The use of the Cloud for robotics and automation brings some potential benefits largely ameliorating the performance of robotic systems. However, there are also some challenges...
IoT (Internet of Things) bridges the physical world and information space. IoT services are environment sensitive and event-driven. The new IoT service architecture should adapt to these features. This paper analyses IoT sensing service characteristics and proposes the future services architecture. It is focused on the middleware architecture and the interface presentation technology. In the middleware...
In Optical Flow Switched networks, the control plane manages the data plane, performs scheduling, reconfigures the network, etc. For large wide area networks the scale of the data plane and the stochastic nature of the requests pose big challenges in achieving both data plane responsiveness/efficiency and control plane scalability which are coupled. In this work, we give an overview of the control...
To apply software architecture techniques in domain specific development becomes an emergent issue. Many industrial domains such as aeronautics, automobile develop their own domain specific ADLs to benefit the advantages of software architecture techniques. However, for small domains, this is very costly in terms of time, manpower and money. However, domain specific software architecture (DSSA) development...
System quality is key part of software system in industry. It not only directly affects the customers/users' satisfaction, but also influences the entire lifecycle of system products from requirement to maintenance. Many quality assurance development methodologies and standards are proposed. However, software evolution as an another important part in software system lifecycle is less studied from...
The development of the mobile Internet brought about by the thriving mobile intelligent terminals has made it possible to access to the Internet anytime and anywhere. While people enjoy the convenience, they also suffer from a series of security threats caused by cyber-attacks. IPS brings reliability and security in a network system and is regarded as one of the most popular security devices. However,...
In component-based software engineering, software architectures govern not only software development but also software evolution. Indeed, to efficiently and accurately manage software evolution and guarantee its quality, architecture models should be at the core of the evolution process, be accurately synchronized with the runtime systems and have their changes and version information be completely...
Computation-intensive multimedia applications are emerging on mobile devices. System-on-Chip (SoC) offers high performance at a decreased size for these devices. SoC often integrates tens of cores and uses Network-on-Chip (NoC) as its communication infrastructure. To ensure high yield of manycore processors, core-level redundancy is often used as an effective approach to improve the reliability of...
Through the technical approach analysis of the Rotorcraft Unmanned Air System (RUAS) in resent ten years, we find that the way of realizing the RUAS development, rapid prototype test platform, and serial RUASs programs are all using the mature manned helicopters to carry out unmanned adaption. Moreover, we think the serial RUAS based on unmanned adaption is the trends in the future. However, there...
The last decade has seen an explosive growth in wireless network services and consequently an increasing demand of high data rates on wireless networks, and the demand of users on real-time traffic is growing. The quality of service (QoS) requirements of different applications are different, for example, the real-time applications are delay-sensitive, yet can tolerant certain data loss. An intrinsic...
Three-dimensional (3D) integration and Network-on-Chip (NoC) are both proposed to tackle the on-chip interconnect scaling problems, and extensive research efforts have been devoted to the design challenges of combining both. Through-silicon via (TSV) is considered to be the most promising technology for 3D integration, however, TSV pads distributed across planar layers occupy significant chip area...
Large scale Chip-Multiprocessors (CMPs) generally employ Network-on-Chip (NoC) to connect the last level cache (LLC), which is generally organized as distributed NUCA (non-uniform cache access) arrays for scalability and efficiency. On the other hand, aggressive technology scaling induces severe reliability problems, causing on-chip components (e.g., cores, cache banks, routers) failure due to manufacture...
Long Term Evolution system represents the latest developments in the direction of UMTS standard. Radio Link Control Protocol layer protocol is an important component of LTE, and its data transmission function plays an important role in the LTE R & D. This paper is concerned with a study of the RLC layer protocol framework, state transitions, and AM mode transmission. Mainly realizes AM transmission...
