Database oriented data grid becomes a new demand with the development of grid technology, and DS_Grid (DatabaSe oriented Data Grid) is such a grid system supporting dynamic data integration with the idea of service. In DS_Grid, MultiChord is adopted as the grid framework implementing the distributed storage, processing and data integration of data service resources and the domain and its corres...

Mutual effects between fixed and mobile broadband technologies remain up to this date largely unexplored. The few studies on this subject produce partially contradictory results. Diffusion oriented analysis approaches focused on cross-product effects on growth. Mutual effects on the market potential level have not been studied. In this article we develop and apply two diffusion models, which co...

Governance has become a huge topic in the business world. Key drivers are increasing regulatory pressure, needs for better risk management, and the desire of enterprises to monitor and influence their business performance faster. IBM’s Unified Governance Framework is intended to cover the entire space of enterprise governance, with a focus on how IT-related services and components can support g...

Tropical varieties play an important role in algebraic geometry. The Bergman complex B(M) and the positive Bergman complex B+(M) of an oriented matroid M generalize to matroids the notions of the tropical variety and positive tropical variety associated to a linear ideal. Our main result is that if A is a Coxeter arrangement of type Φ with corresponding oriented matroid MΦ, then B (MΦ) is dual ...

The basement lamella under the epidermis of amphibian larvae shows a sub-microscopic architecture of remarkable geometric regularity: It consists of about twenty layers of ground substance in which cylindrical fibers (presumably collagenous) of about 500 Angström diameter are embedded parallel to one another, but with the fiber directions alternating by 90 degrees from layer to layer. The repai...

A meta-programming technique known as reflection can be regarded as a sophisticated programming interface for program transformation. It allows software developers to implement various useful program transformation without serious efforts. Although the range of program transformation enabled by reflection is quite restricted, it covers a large number of interesting applications. In particular, ...

Aspect-oriented (AO) programming proposes a solution to the crosscutting problem in Object-oriented (OO) programming by supporting the modularization of crosscutting concerns with new composition mechanisms. This paper evaluates the solution through aspect mining two existing Java code-bases and then refactoring crosscutting concerns found in them into aspects using AspectJ. It documents the pr...

We describe our two query-oriented summarization systems implemented for the NTCIR-9 1CLICK task. We regard a Question Answering problem as a summarization process. Both of the systems are based on the integer linear programming technique, and consist of an abstractive summarization model and a model ensuring to cover diversified aspects for answering user’s complex question. The first system a...

the most important goal of each society, is to reach economic development. as the goal and agent of development, man has got an important responsibility, which responsibility is realized by way of education, specially higher education, because the universities are the main factors for progress, production of knowledge and education of specialized human forces and they play a significant role in...
