Abstract :

Formulation of binary blend of coal-bitumen by weight (blend design involving 10 % bitumen and 90 % of preheated coal samples at about 150 oC) was carried out. The blend was then partially briquetted to increase the bulk density. The feasibility of the blend for the metallurgical coke production was investigated by physico-chemical analysis which revealed that the coking properties of the blend had been improved: particularly the Simonis’ Coking Index (SCI) in LMZ and SKJ which was 0.92 and 0.99. The partial briquetted blend was co-carbonized at high temperature (about 1100 oC) for 15 hours for the metallurgical coke. The calorific value and chemical analysis of the metallurgical coke produced were carried out and the result of SKJ coke found to be close to the acceptable range for use in a blast furnace. Furthermore, the fissuring and abrasion index of the metallurgical coke were evaluated, and only SKJ coke has promising results: Micum 10 (M10) = 26.87 % and M40 = 65.69 % that almost meet the specifications for blast furnace, particularly Ajaokuta Steel Company, Kogi state of Nigeria. The results of this study revealed that the use of bitumen as a bonding substance has upgraded the weakly coking coal to cokeable blend for metallurgical coke making.

Abstract :

The functionality of Cognitive Radio is to detect the presence and absence of licensed user (i.e.) Primary User, in the spectrum, so that the secondary user can use it. Many works has been contributed on spectrum sensing of cognitive radio with single user, which has less complexity but offers inferior detection performance compared to cognitive radio with multiple users. Further there arises hidden user problem in single user system which degrades the system performance. Therefore, it is advisable to use multiple cognitive radio users to sense the spectrum individually and combine their result at the fusion centre. This technique is known as co-operative spectrum sensing. Cooperative sensing is considered to be a boon to the problems that arise in spectrum sensing due to noise uncertainty, fading and shadowing. Further, co-operative sensing decreases the probabilities of miss detection and false alarm to a considerable extent. This paper presents various co-operative spectrum sensing techniques with exhaustive survey and comparison.

Title : Genetic Adaptive Neural Networks for Prediction of Insurance Claims

Authors : Fred Kitchens, Thomas Harris

Abstract :

In the insurance business, an underwriter’s two most important considerations are loss frequency and loss severity (probability of a loss and the financial value of the loss).  Neural networks have been successfully applied to the insurance business in areas such as prediction of loss frequency, and prediction of bankruptcy.  The objective of this study is to develop a neural network model to predict the severity of potential insurance losses in private passenger automobile insurance in the United States.  The study predicts loss severity in private passenger automobile insurance using independent variables commonly available to the insurance underwriter based on the consumer’s application for insurance.  A genetic adaptive neural network training algorithm is used to model the losses.  Premiums are expected to be positively correlated with risk; therefore a linear model is developed as a benchmark, using the same data.  These findings show that loss severity is more difficult to predict than frequency of loss.  Improved results are likely to be found through alternative methodology, or data.

Abstract :

This study presents a sliding mode control and genetic algorithm based sliding mode control of a system with two-bus. The proposed algorithm uses either the coefficients which have been calculated in terms of stability for sliding mode control or the coefficients in the genetic algorithm based sliding mode control which have been calculated by considering stability and optimization. In order to solve the chattering problem of the sliding mode, a solution was offered by obtaining the fast fourier transform of the switching signal and frequency spectrum distribution. Simulation results showed that sliding mode control based on genetic algorithm performs better response than sliding mode control in terms of accuracy.

Title : Business Process Reengineering as a Tool in Total Quality Management makes Engineering Business Sense: A new Perspective and Model

Authors : Philip F. Musa

Abstract :

Business process reengineering (BPR) first made its way into American management lexicon in earnest with the publication of Hammer and Champy’s Reengineering The Corporation: A Manifesto For Business Revolution, in 1993.  However, there were other writers’ works that preceded this publication; notable among these are the publications by James Harrington.  Although lack of standardization is not limited to reengineering, this management concept seems to take this problem to new heights as evidenced by prevalent inconsistencies even in the writings of the same authors.  Regardless of how the various theorists and practitioners define reengineering, it seeks to take advantage of advances in technology to address the goal of cost cutting in organizations.  Too often business managers’ implementations of BPR have seemed to legitimize labor reductions.  Somehow, quality improvement focus was lost in the shuffle.  The premise here is that BPR’s historical conceptualization and implementation has many pitfalls.  These pitfalls are elaborated upon in this article, and an alternative view is presented as to how BPR should be conceptualized and implemented.  This new approach integrates BPR into Total Quality Management (TQM); it also preserves workers’ moral. Merging BPR into TQM shines a much needed positive light on BPR and strengthens the value continuous improvement doctrine in TQM.  The “drastic” and “revolutionary” principles advocated by Hammer and Champy have caused unnecessary dislocations in businesses that implemented it as a separate business practice from TQM. The fundamental issue is the crystallization of what BPR really is.  How should we view it? Is it a management strategy or is it a tool by which higher level management strategies such as TQM could be executed?  We present an alternative conceptualization of business process reengineering.  Therefore, this paper enhances not only engineering knowledge, but the business of engineering knowledge.

Abstract :

Eye-Tracking technologies have strongly increased in deductive reasoning research during the last years. The aim of this paper is to introduce a brief history of its use, to elaborate on some mathematical problems of Eye-Tracking algorithms, to suggest further engineering developments both for hardware and software, to illustrate our proposal with an example of current research on deductive reasoning focused on compound negation, and to discuss the scope and limitations of our contribution. We conclude that Eye-Tracking is a useful tool for Cognitive Science, in general, and for deductive reasoning research, in particular. We also conclude that the future improvement of hardware and software engineering is critical for the potential contribution of this tool to the understanding of human reasoning.

Abstract :

In this paper, we consider an almost periodic multispecies discrete Lotka-Volterra mutualism system with time delays. We first obtain the permanence and global attractivity of the system. By means of an almost periodic functional hull theory and constructing a suitable Lyapunov function, sufficient conditions are obtained for the existence of a unique strictly positive almost periodic solution which is globally attractive. An example together with numerical simulation indicates the feasibility of the main results.
