A major constraint however, is that the expression levels of most of these genes are often collected on relatively few samples which makes the use of classical regression methods inappropriate for genes selection and the prediction of biological samples. A number of methods have been proposed in literature some of which are characterized by procedural complexities. In this book, a novel k sequential genes selection and tumour classification (k-SS) method is proposed. The new k-SS method is very simple to implement and it competes favourably with some selected state-of-the-art methods under varying platforms. Also, a classifier-like preliminary feature selection technique that employs the cross-validated area under the ROC curve for primary gene selection is presented in this book among other results. This book should be a valuable resource for researchers in statistics, medical, pharmacological and biological sciences or anyone that is interested in data mining in science and industry. ····· 10361132749

The first essay deals with the modelling of a perpetual coupon debt structure using two different jump diffusion processes: double exponential and uniform. The second models a debt structure of roll-over perpetual, where the firm s asset value follows a double exponential jump diffusion process. The third develops a model with zero coupon debt structure, and takes into account a stopping time marked by an important negative jump. In our essays, we obtain almost closed form formulae for the debt, equity and firm values, as well as the endogenous default barrier and credit spreads. Levels of credit spreads obtained are closer to the market data and confirm the existence of an optimal capital structure, which takes into account the risk free rate, pay-out ratio, firm risk, tax rate, default costs, and jump intensity & sizes.These essays are designed to provide academic and practitioners with useful and insightful knowledge of credit risk, default event as well as credit spreada. ····· 10361132517

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Water quality degradation is one of the major environmental problems in Addis Ababa and the municipal solid waste dump site can be source of groundwater contamination as leachate may infiltrate and join the aquifer. Despite the potential danger of the Repi landfill (commissioned 4 decades ago with no evaluation of hydro-geologic condition of the area) to the groundwater system, empirical work on the level of sealing of the landfill has been largely scant. The book, therefore, provides geophysical techniques involving 2-D resistivity imaging and VES for a hydro- geophysical assessment of contamination of groundwater. The survey results clearly indicate that the underlying layers around the landfill are weak incapable of preventing downward movement of leachate from the landfill to the groundwater. Hence, the groundwater in this area may have been contaminated. It is hoped that the book can provide useful information for policies and practices aimed at minimizing the environmental impact of solid waste dump sites and should be especially useful to professionals in Environmental geophysics, or anyone else who may be considering utilizing geoelectrical methods. ····· 10361132367

Both these theorems can be jointly stated, as follows. While square numbers can be expressed as a sum of two squares, numbers with higher powers than two can not be expressed as a sum of two like powers. At the end of the HMN, Fermat stated that he had a marvelous demonstration (Proof) of this proposition (FLT), but it could not be traced. In this monograph a proof of FLT closest to Fermat`s thought-process has been presented. This proof is based on techniques known during Fermat`s time. Thus, this proof meets the aspirations of those connoisseurs of number theory who are looking forward to get the glimpses of Fermat`s thought-process, while writing his HMN.

We discussed the methods for finding the optimal (maximum and minimum) solution of inverse problem of fuzzy relation equation of the form R o Q = T where for both cases R and Q are kept unknown interchangeably using different operators (e.g. alpha, sigma etc.). The aim of this study is to make an in-depth finding of best project among the host of projects, depending upon different factors (e.g. capital cost, risk management etc.) in the field of civil engineering. On the way to accomplish this aim, two linguistic variables are introduced to deal with the uncertainty factor which appears in civil engineering problems. Alpha-composition is used to compute the solution of fuzzy relation equation. Then the evaluation of the projects is orchestrated by defuzzifying the obtained results.

The rate of urbanization, on the other hand, refers to the speed at which a country is urbanizing. Urban areas have long been associated with economic growth and prosperity. However, as populations, industries and services get attracted to urban centers, urbanization, if not well managed, may come with a number of environmental challenges, prominent among which are water and air pollution, poor solid and liquid waste management, disappearance of urban greenery, loss of biological diversity, and sub-urban sprawl. The environmental challenges faced by urban planners and managers, as well as urban dwellers in general form the basis of this book. The book tries to highlight the causes and effects of these environmental challenges, particularly in less developed countries, and suggests possible codes of practice that might minimize the challenges. Among the suggestions proffered is the need for environmental education, public involvement and urban planning that integrates environmental considerations at all stages of urbanization and urban development. ····· 10361131786· 1 · ::::: · 6 ·· 7 ·· 8 ·· 9 ·· 10 ·· 11 ·· 12 · ::::: · 26 ·
