RLST: Its Origin and Development, an Interview with Prof. Jafar Mehrad

J. Mehrad

Volume 5, Issue 2 , July 2007, Pages 1-9

  Regional Library of Science and Technology (RLST), located in Fars State, is one of the international institutions of the Ministry of Science, Research and Technology which is active in the area of information production and dissemination. The following interview is aimed at providing the information ...  Read More

Survivable Network Systems: Its Achievements and Future Directions

M. Keshtgary; A. H. Jahangir

Volume 5, Issue 2 , July 2007, Pages 11-34

  Society is growing increasingly dependent upon large-scale, highly distributed systems that operate in unbounded open network environments. Unless safeguards are incorporated in the system, a failure of even a single component, e.g. a link or a node, can significantly impact the network performance ...  Read More

Multiobjective Geometric Programming with Fuzzy Parameters

H.R. Maleki; M. Mashinchi

Volume 5, Issue 2 , July 2007, Pages 35-45

  Generally, an engineering design problem has multiple objective functions. Some of these problems can be formulated as multiobjective geometric programming models. On the other hand,often in the real world, coefficients of the objective functions are not known precisely. Coefficients may be interpreted ...  Read More

Geo-Metadata Creation Using GML Technology

A. Kalantari Oskou’ee

Volume 5, Issue 2 , July 2007, Pages 47-65

  Nowadays, standardized metadata for geospatial data is a key in sharing and finding information on the web and crucial in building Geospatial Data Infrastructure (GDI). The main objective of this paper was to develop a web-based metadata dissemination system for in-situ sensors based on, most importantly, ...  Read More

A New Adaptive and Intelligent Traffic Shaper for High Speed Networks

A. A. Safavi; I. Shames; N. Najmaei; M. Zamani

Volume 5, Issue 2 , July 2007, Pages 67-82

  In this paper, the advantage of reinforcement learning to develop a new traffic shaper is invoked in order to obtain a reasonable utilization of bandwidth while preventing traffic overload in other parts of the network. This leads to a reduction in the total number of packet droppings in the whole ...  Read More

Bandwidth Estimation in Wireless Networks (TCP-bwiw): to Improve TCP Performance in Wireless Communication Networks

A. Ezil Sam Leni; S. K. Srivatsa

Volume 5, Issue 2 , July 2007, Pages 83-91

  As wireless networks with high data rate get widely deployed, improving the performance of TCP over these networks plays vital role. Wireless link losses have dramatic adverse impact on TCP performance due to the difficulty in distinguishing the congestion losses from wireless link losses. We first, ...  Read More

Does Simple Binary Crossover Hasten RCGA Convergence?

C. Lucas; A. Nayyeri; M. Yabandeh

Volume 5, Issue 2 , July 2007, Pages 93-98

  Real Coded Genetic Algorithm, RCGA, is the type of GA which operates on chromosomes with real valued parameters. Different mutation and crossover operations are defined for RCGA. One usable crossover for this kind of GA is to consider its chromosomes simply as bit strings and utilize the same operations ...  Read More

On-Line Identification of Non-Linear Systems Using Adaptive RBF-Based Neural Networks

K. Salahshoor; M. R. Jafari

Volume 5, Issue 2 , July 2007, Pages 99-121

  This paper extends the sequential learning algorithm strategy of two different types of adaptive radial basis function-based (RBF) neural networks, i.e. growing and pruning radial basis function (GAP-RBF) and minimal resource allocation network (MRAN) to cater for on-line identification of non-linear ...  Read More

Evaluation of Spread Spectrum Watermarking Schemes in the Wavelet Domain Using HVS Characteristics

A. Zolghadrasli; S. Rezazadeh

Volume 5, Issue 2 , July 2007, Pages 123-139

  In this paper, we introduce a multiresolution watermarking method for copyright protection of digital images. The method is based on the discrete wavelet transform. A noise type Gaussian sequence is used as watermark. To embed the watermark robustly and imperceptibly, watermark components are added ...  Read More
