Network security is very important when sending confidential data through the network. Cryptography is the science of hiding information, and a combination of cryptography solutions with cognitive science starts a new branch called cognitive cryptography that guarantee the confidentiality and integrity of the data. Brain signals as a biometric indicator can convert to a binary code which can be...

Quantum information processing exploits the quantum nature of information. It offers fundamentally new solutions in the field of computer science and extends the possibilities to a level that cannot be imagined in classical communication systems. For quantum communication channels, many new capacity definitions were developed in comparison to classical counterparts. A quantum channel can be use...

This report gives an insight about two major aspects of information theory, including data compression and channel coding. It discusses the simulations results obtained using MATLAB from the information theory view point. It also defines these aspects by using the definitions of entropy and mutual information which reflects the optimum data compression could be obtained and the ultimate transmi...

: In this article, the ‘information channel diagram’ (ICD) approach is introduced as a diagrammatical tool for modelling information flow during the delivery phase of organisations in which goods are deployed or delivered to customers. An initial review and evaluation of current tools for modelling information flow will be conducted based on the characteristics of information flow during the de...

in synthetic aperture radar (sar) imagery, ship-sea contrast can be significantly improved when the polarimetric information is used, compared with information from a single channel sar. the constant false alarm rate (cfar) detection algorithm based on the alpha-stable (as) distribution model is a descent method for ship detection in sea. the most important step in this method is the parameter ...

This is an introduction to Shannon’s Information Theory. It is more like a long note so that it is by no means a complete survey or completely mathematically rigorous. It covers two main topics: entropy and channel capacity. All related concepts will be developed in a totally combinatorial flavor. Some issues usually not addressed in the literature will be discussed here as well. Hopefully, it ...
