Design and implementation of data warehouses remain delicate tasks which are led by experts. Nevertheless it would be interesting to allow the users to define and to build themselves their system through a simple and flexible process. In particular, in the field of production systems, exists the need to integrate data from various sources and to analyze them in order to extract knowledge for op...

We present a cortical model of cognitive control based on attractor networks, correlational learning, and gating. Our model does not make use of production rules or local representations. It is capable of completing a demonstration task requiring adding to and examining working memory. The architecture used is easily generalizable to other tasks.

This paper looks at differences in spatial and temporal variation of rice yields in China and Brazil. We find that rice yields in China have converged over time and that rice production has become more and more homogeneous. In contrast, rice yields in Brazil have diverged over time, primarily due to variations in upland rice yields. Three hypotheses are put forward to explain the different beha...

this article has attempted to present a clear image of science production by the member states of the organization of islamic conference (oic) based on the essential science indicators (esi). esi indexes the most effective science productions of the world. the world bank, on the other hand, has classified the countries of the world according to their economic position. using the information acc...

Fluid flow models have been used in performance evaluation of production, computer, and telecommunication systems. Currently, a general methodology to model and analyze a given continuous flow production system is not available. In order to develop a general methodology to analyze Markovian continuous material flow production systems with a finite buffer, we modelled the fluid flow system as a ...

This paper explains an implementation model for a new method for Production Leveling designed for batch production system. The main structure of this model is grounded on three constructs: traditional framework for Operations Planning, Lean Manufacturing concepts for Production Leveling and case study guidelines. By combining the first and second construct, a framework for Production Leveling h...

Production leveling is an essential element of the Toyota Production System. It aims at balancing production volume as well as production mix to reduce waste, overburden, and unevenness. The application of conventional leveling approaches is limited by the requested product diversity. Because of this production leveling is predominantly used in high volume production. Nevertheless it can be imp...

Streaming data, consisting of indefinitely evolving sequences, are becoming ubiquitous in many branches of science and in various applications. Computer scientists have developed streaming applications such as Storm and the S4 distributed stream computing platform1 to deal with data streams. However, in current production packages testing and evaluating streaming algorithms is cumbersome. This ...

BACKGROUND Several systems have been proposed to rank academic institutions worldwide. We aimed to introduce a new method of Health Research System (HRS) evaluation in Iran. METHODS In this cross-sectional study, a specific questionnaire has been used to assess stewardship, capacity building, and knowledge production through annual evaluations of HRS in Iran. This article has explored the res...

Chile has chosen different strategies to manage its rich marine resources while meeting the demands from domestic and increasing foreign markets. One strategy involves giving user (fishers, collectors of non-fish resources) organizations rights to manage and exploit certain target species in a public and limited area/volume of the sea in Management Areas for the Exploitation of Benthic Resource...
