In the information age and with explosively increasing volumes of remote sensing, model and other Earth Science data available, scientists are now facing challenges to find and to access interesting data sets effectively and efficiently through the Internet. In this paper, we first discuss the DIstributed MEtadata Server (DIMES) prototype system. Designed to be flexible yet simple, DIMES uses X...

Aimed at overcoming subjectivity and improving the accuracy of traditional production performance evaluation methods for manufacturing enterprises, a new model of performance evaluation was proposed based on rough sets and a wavelet neural network (RS WNN). Firstly, an evaluation index system considering innovation performance was constructed. Secondly, a theory of rough sets and fuzzy mathemat...

As H2020 approaches and open access policies spread in the European research community ([9]), it becomes more important to revisit the basic concepts in software distribution such as free software, open source software, licenses: they should be considered before any research software dissemination. We also propose here a distribution procedure that can be adapted for software and data dissemina...

Component-based software development would allow application software be largely constructed, rather than programmed. This approach would dramatically improve the productivity of software development. Although there are many reusable software packages available, the integration of the chosen parts remains to be a very difficult problem because there are many barriers of integration, including p...

We count the number of alignments of N ≥ 1 sequences when match-up types are from a specified set S ⊆ N . Equivalently, we count the number of nonnegative integer matrices whose rows sum to a given fixed vector and each of whose columns lie in S. We provide a new asymptotic formula for the case S = {(s1, . . . , sN ) | 1 ≤ si ≤ 2}.

A simple procedure to tighten the Lagrangian bounds is proposed. The approach is interpreted in two ways. First, it can be seen as a reformulation of the original problem aimed to split the resulting Lagrangian problem into two subproblems. Second, it can be considered as a search for a tighter estimation of the penalty term arising in the Lagrangian problem. The new bounds are illustrated by a...

Given two point sets S and T , we study the many-to-many matching with demands problem (MMD problem) which is a generalization of the many-to-many matching problem (MM problem). In an MMD, each point of one set must be matched to a given number of the points of the other set (each point has a demand). In this paper we consider a special case of MMD problem, the one-dimensional MMD (OMMD), where...

This paper describes ThreadMon, a monitoring tool for improving the performance of multithreaded programs, and how we have used it to examine various aspects of the many-to-many (or two-level) threads implementation model. We run unmodified binary subject code, insert software probes to collect data, and analyze and present the results in real time on another machine. We show that the behavior ...

Software Defined Network interoperate with other technologies like flow visor and open flow. This enables slicing of the network in many ways, including MAC, IP and VLAN. It also enables seamless interconnections with multiple controllers, providing the ability to run multiple applications each on a different controller. The purpose of this interoperability analysis is to test the applications ...

1 Pong P. Chu, Electrical and Computer Engineering Department, Cleveland State University, Cleveland, OH 44115, [email protected] Abstract  Programmable devices and EDA (Electronic Design Automation) software tools are widely used to design today’s digital systems. Many introductory digital systems courses are aware of the trend and integrate the technology, especially HDL (Hardware Descriptio...
