The decision-making process can be supported by many tools such as Data Warehouse (DW), On-Line Analytical Processing (OLAP) and Geographical Information System (GIS). Much research found in database literature is aimed at integrating these technologies. However, most of them do not specify neither evaluate multidimensional-geographical processing algorithms. This paper proposes two algorithms,...

Grid computing provides high computing power, enormous data storage, and collaboration possibilities to its users. In the networked access to computation with a single-sign-on system as the portal to the possibilities of world wide computing grids security plays an important role. This paper provides an overview about the state-of-the-art of security in current grid technologies and a discussio...

We present a study of web user behavior when network performance decreases causing the increase of page transfer times. Real traffic measurements are analyzed to infer whether worsening network conditions translate into greater impatience by the user, which translates in early interruption of TCP connections. Several parameters are studied, to gather their impact on the interruption probability...

This paper presents the application of a connection-ist control-learning system to an autonomous mini-robot. The system's design is severely constrained by the computing power and memory available on board the mini-robot and the on-board training time is greatly limited by the short life of the battery. The system is capable of rapid unsupervised learning of output responses in temporal domains...

The ICDAR Robust Reading Competition (RRC), initiated in 2003 and re-established in 2011, has become the defacto evaluation standard for the international community. Concurrent with its second incarnation in 2011, a continuous effort started to develop an online framework to facilitate the hosting and management of competitions. This short paper briefly outlines the Robust Reading Competition A...

In this paper, the advantage of the use of an NoC with reconfigurable Routers has been presented instead of homogeneous ones. . In this paper we propose the use of a reconfigurable router, where the buffer slots are dynamically allocated to increase router efficiency in an NoC, even under rather different communication loads. In the proposed architecture, the depth of each buffer word used in t...

This article study chip communication mechanisms deeply based on the NoC (Network on Chip) technology and a load equalization of virtual channel (LEVC) routing algorithm for Torus networks is proposed, which splits the physical network into virtual networks in the case of physical link load equalization. According to the predefined rules, packets use different virtual networks on their way to d...

Specifically, based on the observation that a response is always preceded by a request in multi-processor SoCs, this letter proposes a novel deadlock-free XY-YX router for on-chip network performance improvement. In order to avoid deadlock, we add additional physical channels in the horizontal direction and optimize the priority of output channel allocation. Simulation results show the enhancem...

It is a challenging topic to perform pattern reconstruction from a unit-width skeleton, which is obtained by a parallel thinning algorithm. The bias skeleton yielded by a fully-parallel thinning algorithm, which usually results from the so-called hidden deletable points, will result in the difficulty of pattern reconstruction. In order to make a fully-parallel thinning algorithm pattern reconst...
