Review of Science and Technology Status in Iran

S. Afsharnia; S. Vaez-Zadeh

Volume 3, Issue 1 , July 2005, Pages 3-17

  The experiences by different societies reveal that consistent social and economic development results from the development of science and technology, and that the latter takes place only in a process that includes: comprehensive policy making; precise planning; determining relevant strategies and finally ...  Read More

The Web Search Engines and General Reference Questions

Z. Hayati; R. Alijani

Volume 3, Issue 1 , July 2005, Pages 18-32

  Six Web search engines, namely, Altavista, Excite, Go, Google, Hot Bot and Lycos, were compared and evaluated in terms of their search capabilities (i.e., duplicate, false drops, mirror sites, dead links) and retrieval performances (i.e., precision) using sample queries drawn from real reference ...  Read More

An Alternative Approach to Security Concerns in Digital Library Initiatives

N. Naghshineh

Volume 3, Issue 1 , July 2005, Pages 33-46

  Digital preservation refers to an important aspect that most Iranian digital library initiatives lack. This component is Security. While a digital library may be misconceived as an information supply space without a physical form, the same security concerns in force for operation of physical library ...  Read More

Adaptive Non‑Uniform Rate Sampling and Application in Data Compression

A. Zolghadrasli

Volume 3, Issue 1 , July 2005, Pages 47-56

  In this paper the author considers a general method, based on time domain samples for spectral manipulation of time limited signals. First, the original signal is divided into some frames in the time domain. Then, by presenting a suitable theoretical and computational algorithm, and using a method ...  Read More

Application of Passive Gg-Aero Stabilization for Near-Earth Small Satellites

H. Bolandi; A. Badpa; M. Nasiri Sarvi

Volume 3, Issue 1 , July 2005, Pages 57-71

  When the orbital altitude of a small satellite is near-Earth, passive stabilization can be considered. The purpose of this paper is to combine the passive gravity gradient and aerodynamic stabilization methods together so that all the three axes stabilizations can be obtained. In this regard, the ...  Read More

An Approach Towards Solving Large-Scale Allocation Problems (Modeling and Solution Algorithm)

S. M. Khalesizadeh; A. Basirian Jahromi

Volume 3, Issue 1 , July 2005, Pages 72-86

  Large-Scale Allocation Problem (LSAP) is considered to be an important problem in Operations Research. In this paper, we have tried to model a sample LSAP and show that famous linear OR approaches in use cannot efficiently help us challenge, develop and handle such cases. We begin with efforts in ...  Read More
