Abstract: A new distributed computer system used for real-time monitoring and protecting of mine steel-cord belt conveyor is developed and introduced in this paper. It can accomplish the on-line monitoring of some faults of the conveyor, such as splice breaking, longitudinal rip, fire and tension super-threshold etc. Simulation experiments and industrial experiments show that this system possesses many advantages such as general, high reliability, lower cost, easy installation, evidential suitability, etc. So it is feasible.

Abstract: The paper applies the location quotient method to analyze the position of the industry in Wuhan and expounds its outside environments and foresees its development tendency in the angle of the structures like industry, product and technology and of the industrial operating mechanism. On the base of the above analysis, the paper puts forward the importance, namely, the industrial construction in industrial clusters, information, service and brands in developing the industry in Wuhan.

Abstract: Importance measures are widely used to characterize the contribution of components to the system performance such as reliability, availability, risk, etc, and thus give great help in identifying system weaknesses and prioritizing system improvement activities. Although much work has been carried out on component importance analysis, most studies only concern the consistent states of components within which components exhibit consistent performance until state changes happen. Unfortunately, field data shows that many transient faults in components may result in severe consequences without causing any state changes, and, this can lead to a misunderstanding of component importance. This paper focuses on the reliability importance analysis in presence of transient faults, and proposes a composite measure for evaluation. A sample series parallel system is analyzed to illustrate the use of this measure.

Abstract: Availability is one of the key features for transaction processing systems. Fault injection is one of the important techniques to hasten availability tests. A fault injection platform is designed in this paper for IA64 system which is being widely used in transaction processing business. The fault injection platform is implemented using client/server mode and a series of fault injection tools are accomplished which covers CPU faults, memory faults, disk faults, IO faults, file system faults and system call boundary errors. A group of experiments on a typical IA64 server are described and performed, and the experiment results validate the effectiveness of the fault injection platform.

Abstract: Handle official business specifically for at present mature business system is moving the aspect deficiency, be applied or used universally having suggested that one kind of business system combines with displacement terminal appearance moves the middleware. And by the design studying the population having given the displacement being applied or used universally out the middleware, scheme composing module detailed design as well as important, have given out at the same time suitable match tier suitable match the algorithm, inquiry decomposition algorithm , inquire about the result XML form encapsulation algorithm, have realized middleware of that displacement system. The at last has verified the feasibility owing the centre being applied or used universally moving a middleware combining with some company's handling of goods and materials business system.

Abstract: In real world, high-dimensional data are everywhere, but the nature structure behind them is always featured by only a few parameters. With the rapid development of computer vision, more and more data dimensionality reduction problems are involved, this leads to the rapid development of dimensionality reduction algorithms. Linear method such as LPP [1], NPE [2], nonlinear method such as LLE [3] and improvement version kernel NPE. One particularly simple but effective assumption in face recognition is that the samples from the same class lie on a linear subspace, so lots of nonlinear methods only perform well on some artificial data sets. This paper emphasizes on NPE and SPP [4] come up with recently, and combines these methods, the experiments show the effect of new method outperform some classic unsupervised methods.

Abstract: Process composition with shared resources is a kind of composition that all participants share common resources that cannot be consumed and must be returned after using. Properties of the composited process and conditions of property preserving of participants are studied in this paper. Moreover sharing graph of composited process is defined and constructed to judge whether the composition is structural sound or not. And devices to keep the structural soundness of participants are given also.

Abstract: A new type of networked manufacturing — cloud manufacturing is forming and developing with the development of information technology and manufacturing industry. This paper gives the definition of cloud manufacturing and puts forward a structure of cloud manufacturing system. At the same time we discuss the key technologies for realization of resource encapsulation of cloud manufacturing by using EDDL technology.

Abstract: A highly efficient, single-port SRAM-based loop filter based on H.264 is presented. Hybrid edge filtering order, efficient memory organization for both on-chip SRAM and transposition buffers, and five-stage pipeline architect are adopted in the design. Efficient transposition buffer organization reduces the gate counts and the memory access times. By using hybrid edge filtering order and alternating output memory update scenario, zero stall cycle in pipeline flow is realized. To balance on-chip memory size and bus bandwidth, the design can be configured to operate in on-chip memory and off-chip memory modes.
