Introduction: This study aims to comparatively review the rehabilitation information systems in 8 countries: Canada, the United States, the United Kingdom, Sweden, Australia, Malaysia, Russia, and Iran. Methods: A comprehensive review of published studies without a time limit was explored by searching the keywords, titles, and abstracts. Studies were obtained from the Web of Science, Scopus, P...

in this paper by use of mathematical modeling of an observer [14,15] the notion of relative information functional for relative dynamical systemson compact metric spaces is presented. we extract the information function ofan ergodic dynamical system (x,t) from the relative information of t fromthe view point of observer χx, where x denotes the base space of the system.we also generalize the inv...

Social cataloging sites—tagging systems where users tag books—provide us with a rare opportunity to contrast tags to other information organization systems. We contrast tags to a controlled vocabulary, the Library of Congress Subject Headings, which has been developed over several decades. We find that many of the keywords designated by tags and LCSH are similar or the same, but that usage of k...

In information retrieval systems, it is very important that indexing is defined very well by appropriate terms about documents. In this paper, we propose a simple retrieval model based on terms distribution characteristics besides term frequency in documents. We define the keywords distribution characteristics using a statistics, standard deviation. We can extract document keywords that term fr...

purpose: libraries and information centers as information storage and retrieval systems can develop with the adoption of cybernetics rules. this paper discusses system dynamics, control, feedback, and other cybernetic concepts especially in information storage and retrieval systems. methodology: this study is a review intending to find what cybernetics and lis have in common especially in the f...
