As a result of the research and design of reconfiguration router unit (RRU), the producing of network equipment is turned into component composition as building block. Based on the component composition and the character of RRU, this paper proposes the concept-CCS (component candidate set). The scheme of creating component candidate set is based on the BP neural network. The CSS is proposed to resolve...
As part of the DARPA sponsored high productivity computing systems (HPCS) program, IBM is building petaflop supercomputers that will be fast, power-efficient, and easy to program. In addition to high performance, high productivity to the end user is another prominent goal. The challenge is to develop technologies that bridge the productivity gap - the gap between the hardware complexity and the software...
OGSA-DQP provides distributed query processing functionalities on top of OGSA-DAI, presenting the multiple databases as a single one, but it does not address heterogeneous data semantic integration requirements. This paper show the query reformulation based on rules on top of OGSA-DAI and OGSA-DQP, which can implement heterogeneous data semantic integration, and users can submit queries over a single...
Most database applications are designed according the ANSI/SPARC architecture. When it is used a large amount of semantics of data may be lost during the transformation from the conceptual model to a logical model. As a consequence exchanging/integrating various databases or generating user interfaces for data access become difficult. Ontologies seem an interesting solution to solve these problems,...
Keyword search provides a simple yet effective way for the users to query and explore the underlying documents. In the recent years, there have been a great deal of research and development activities on extending keyword search capabilities to handle relational data, the dominant form in which business data are stored. Algorithms and prototype systems, such as Discover, DBXplorer, BANKS, and SPARK,...
Recently, with wide-spread of distributed systems, distributed monitoring systems are needed to mange such systems. However, since monitoring architecture of distributed system faces a huge amount of log data which come from local computing nodes, information aggregation is fundamental scheme for monitoring distributed system. In this paper, we preset a novel approach for extracting computing node-condition...
Nowadays, when the evolution of IT tools is faster than ever, the user's needs are evolving even faster. For a software company such a context is difficult to be handled because, within a classical development cycle, the development of an application takes several months or years delivery. A rapid software prototyping could be very useful in those cases helping the user to rethink its needs in terms...
According to the actual situation in the integrated statistical work of coal enterprise in our country now, we determined using the exploitation method of combining SAD and object oriented by analyzing the system's function characteristic, has established the composite structure model which C/S and B/S unify. The system has realized many essential functions such as the technical specification dynamic...
We present a solution to the Secure Multi-party Computation (SMC) problem in the form of a protocol that ensures zero-hacking. The solution comprises of a protocol with several trusted third parties (TTPs) where there is a possibility of threat to the security. Our protocol unanimously selects one TTP among all TTPs in the SMC architecture that owns the responsibility of all the computation in the...
In the framework of meaning representation in Natural Language Processing (NLP), we aim to develop a system that can be used for heterogeneous applications such as Machine Translation, Information Retrieval or Lexical Access. This system is based on six hypotheses which concern meaning representation and acquisition. In this paper, we discuss the related hypotheses that motivate the construction of...
Efforts for software evolution supersede any other part of the software life cycle. Technological decisions have a major impact on the maintainability, but are not well reflected by existing code or architecture based metrics. The way the persistency of object structures with relational databases is solved affects the maintainability of the overall system. Besides maintainability other quality attributes...
Next-generation distributed CORBA applications and services must be flexible, reusable, and capable of providing scalable, low-latency quality of service (QoS) to delay-sensitive applications. Caching is an important technique to improve performance for critical and real-time distributed applications. In this paper, we provide a unified object caching architecture (based on caching proxies that use...
