A complete review based on various aspects of pulverized coal combustion

Coal is the most abundant energy source, and around 40% of the world's electricity is produced by coal combustion. The emission generated through it put a constraint on power production by coal combustion. There is a need to reduce the emissions generated through it to utilize the enormous energy of coal for power production. Detailed understanding of various aspects of coal combustion is required to reduce the emissions from coal‐fired furnaces. The aim of present paper is to review various aspects of pulverized coal combustion such as oxy‐fuel combustion, co‐combustion of coal and biomass, emissions from pulverized coal furnaces, ash formation and deposition, and carbon capture and sequestration (CCS) technologies to outline the progress made in these aspects. Both experimental and numerical aspects are included in this review. This review also discusses the thermodynamic aspects of the combustion process. Furthermore, the effect of various submodels such as devolatilization models, char combustion models, radiation models, and turbulent models on the process of pulverized coal combustion has been investigated in this paper.     

XOR transform with actin quantum automata for better security against cryptanalysis

XOR is a basic cryptographic transform, used as a one way function inside of complex cryptosystems. In this paper we propose first of a kind design of the XOR transform with a universal logic designing paradigm. The system offers enhanced security to the transform by propagating randomly generated information along with the XOR output over the unsecured channel. This additional security is a inherent attribute of the actin automata and is exploited in this paper. The system can be enacted on a Partitioned one-Dimensional Quantum Cellular Automata. A simulation of the proposed system is illustrated with Simulink tool in MATLAB. Based on the work done by Adamatzky et al. we observe that the actin automata is capable of operating on quantum input bits and can generate appropriate results when required. In this paper, the actin automata is simulated with classical bits instead of quantum bits for designing the transform. We have also tried to establish the proposed system by means of low power consumption verified with NI Multisim and comparison with cryptographic complexity with traditional XOR transform. Additionally, we have analyzed the system for enhanced cryptanalytic complexity against various attacks.

     

A study on remanufacturing possibility of a product

With the intensification of Globalization, customers’ environment-friendly attitude and stringent environmental regulations, the manufacturers have been orienting their manufacturing and other value additive processes towards the development of more environment-friendly products and use of relevant processes including taking back of used products after their end-of-use or end-of-life from the end users. Remanufacturing is one of the prominent and popular options. Remanufacturing perhaps has drawn maximum attention because of its economic viability and environmental cleanliness. The remanufacturing operation depends upon the quality and quantity of the used. Better the quality lesser the remanufacturing cost. A remanufacturer is unaware about the condition of used product before its acquisition. It may also be noted that the remanufactured product may be taken after a period of its use by users. So it is really difficult to judge how many cycles does the product go for remanufacturing. This has drawn the attention of the authors and the problem is studied with developing some mechanism on the possible frequency of the remanufacturing of a new product. This paper is a study report on this area of research which is expected to contribute immensely to the remanufacturing business.
