THREE COORDINATE SYSTEMS FOR INFORMATION SCIENCE APPROACHES

channel estimation for mimo-ofdm systems

تخمین دقیق مشخصات کانال در سیستم های مخابراتی یک امر مهم محسوب می گردد. این امر به ویژه در کانال های بیسیم با ‏خاصیت فرکانس گزینی و زمان گزینی شدید، چالش بزرگی است. مقالات متعدد پر از روش های مبتکرانه ای برای طراحی و آنالیز ‏الگوریتم های تخمین کانال است که بیشتر آنها از روش های خاصی استفاده می کنند که یا دارای عملکرد خوب با پیچیدگی ‏محاسباتی بالا هستند و یا با عملکرد نه چندان خوب پیچیدگی پایینی...

Quantitative Approaches for Modeling Information Quality in Information Systems

Coordinate Systems for Supergenomes

Background: Genome sequences and genome annotation data have become available at ever increasing rates in response to the rapid progress in sequencing technologies. As a consequence the demand for methods supporting comparative, evolutionary analysis is also growing. In particular, efficient tools to visualize -omics data simultaneously for multiple species are sorely lacking. A first and cruci...

Recent Development in Information Science: Implications for Information Systems Research

Over past several decades, the management information systems (MIS) community has adopted theories, methodologies, philosophical bases, and assumptions from sister disciplines. This paper reports the changing nature of information science (IS) towards multi-disciplinarity and its development over the past decade. It also examines the contribution of informetrics to MIS research in delineating t...

Biological and Information Systems Approaches

INtrODUctION Knowledge of past activities, discoveries, and events is applied by businesses to support everyday operations in much the same manner that human beings use their personal memories. But the true nature of organizational memory (OM) remains obscure, and information-systems practitioners have no clear definitional model of what they are working toward and have been unable to build a c...
