Nowadays, enterprises cooperate more extensively with other enterprises during the entire product life cycle. Temporary alliances between various enterprises emerge such as those in Virtual Enterprises. Collaborative applications are demanded that enable enterprises to engage in such endeavors. This paper aims to present a framework with which collaborative applications can be characterized and...

The Virtual Company educational scenario engages students in a professional setting for working and learning. Students are enabled to develop competencies that are derived from professional practice. This allows us to use assessment strategies that are different from the practice in traditional educational settings. In the Virtual Company educational scenario the competence assessment procedure...

Introduction:     women's  employment  is one of the fundamental problems in breastfeeding. Studies have shown that after delivery, amount of milk is  equal in the mothers working and non-working. But  after several   months will be reduced markedly. Methods: In this study, with different departments was done coordination , and interviewed with the 351 mothers that had children under two years...

BACKGROUND Commercial fishing is an extremely dangerous economic activity. In order to more accurately describe the risks involved, a specific injury coding based on the working process was developed. METHOD Observation on six different types of vessels was conducted and allowed a description and a classification of the principal working processes on all kinds of vessels and a detailed classi...

In recent years, production of text documents has seen an exponential growth, which is the reason why their proper classification seems necessary for better access. One of the main problems of classifying text documents is working in high-dimensional feature space. Feature Selection (FS) is one of the ways to reduce the number of text attributes. So, working with a great bulk of the feature spa...

We revisit classical sieves for computing primes and analyze their performance in the external-memory model. Most prior sieves are analyzed in the RAM model, where the focus is on minimizing both the total number of operations and the size of the working set. The hope is that if the working set fits in RAM, then the sieve will have good I/O performance, though such an outcome is by no means gua...

The delayed delivery of the AIRBUS A380© demonstrates the challenges to be faced in the field of cross-company collaboration today. On the one hand, available CWE platforms are used insufficiently. On the other hand, they do not yet support collaboration in a completely adequate way. This paper illustrates the current state of CWE practice by way of a sample company, its internal and external c...

In the last years the quantity of text documents is increasing continually and automatic document classification is an important challenge. In the text document classification the training step is essential in obtaining good results. The quality of learning depends on the dimension of the training data. When working with huge learning data sets, problems regarding the training time that increas...

Support Vector Machines are learning paradigm originally developed on the basis of a binary classification problem with signed outputs ±1. The aim of this work is to give a probabilistic interpretation to the numerical output values into a multi-classification learning problem framework. For this purpose, a recent SV Machine, called `-SVCR, addressed to avoid the lose of information occurred in...
