These problems have many applications, in particular in data mining, computational biology, computational chemistry, and medicine.Numerical methods for GO are often very time consuming and could not be applied for high-dimensional non-convex and/or non-smooth optimization problems. This is the reason of this book why to develop and study new algorithms for solving large-scale GO problems.The existing local/global optimization techniques effectively solve many problems when the number of variables is not very large and, as a rule, fail to solve many large-scale problems. The study of new algorithms which allow one to solve large-scale GO problem is very important. One technique is to use hybrid of global and local/global search algorithms. When the gradient (or its generalizations) of theobjective functions and the constraint functions are very complex in form or they are not known, the derivative-free methods benefit the large-scale GO problems. This book presents several derivative-free hybrid methods for large-scale GOproblems, & applied to data mining, biochemstry, biomedicine. ····· 10361134000

The role of visualization tools in knowledge discovery, while acknowledged as an important step in the process is not clearly defined as to how it influences subsequent steps or exactly what the visualization reveals about the data before those steps take place. The research work described, by showing how known structures in test data sets are displayed in the visualization tools considered, indicates the definite knowledge, and limitations on that knowledge, that may be gained from those visualization tools. The major contributions of the book are: to provide an objective assessment of the effectiveness of some representative information visualization tools under various conditions to suggest and implement an approach to developing standard test data sets on which to base an evaluation to evaluate the chosen information visualization tools using the test data sets created to suggest criteria for making a comparison of the chosen tools and to carry out that comparison. ····· 10361133938

Studies in this field have primarily been based on models, which can either be described as empirical or theoretical. Part of the current study is to understand fluid flow in porous media through studying three recent theoretical pore-scale models based on the concept of a Representative Unit Cell (RUC), to represent a porous medium. Amongst other assumptions, these models assumed plane Poiseuille flow throughout each pore section of a rectangular RUC. The main objective of this study is to numerically verify this assumption using Computational Fluid Dynamics (CFD) software, FLUENT version 6.2.16. Attention is also paid to comparison between these models with the experimental data, obtained during the model tests of airflow through a timber stack end, undertaken in a wind tunnel. The laminar and intermediate airflow through a timber stack end is simulated using the commercial software FLUENT, and the results are validated against the theoretical pore-scale models and experimental data. ····· 10361133783

A new method that combines multi-resolution analysis (MRA) and classical Fourier spectral methods to identify peaks in the power spectral density of a given time series is proposed. The method is validated on specially designed test signals. The proposed method is then applied to the rainfall time series, especially to help separate closely spaced periodicities. In this procedure, using MRA the stationary component of the rainfall time series is first identified. Then (partially) reconstructed time series are derived over each wavelet scale band in the stationary component. The significance of the detected peaks is then determined using a chi-squared test against the reference spectra, which together represent a noise process spectrally close to rainfall. A new quantitative definition of spectral homogeneity is also proposed which identifies new spectrally homogeneous region in Indian sub-continent.

Among these disciplines palynology is one of the most significant tool used by modern taxonomists to identify and differentiate closely related taxas. Pollen characters have received great attention in taxonomic classification as they show more stability in their characters than morphology. The significance of pollen morphology in plant systematic has been stressed by a number of workers to delineate different taxa in terms of phylogenetic and taxonomic consideration. This monograph will shed some light on pollen morphology of medicinally important herbal flora of tropical and subtropical regions, and will be source of useful information not only for taxonomist but also for the people related to herbal pharmaceutical industries. ····· 10361133681

für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Recent assessments indicate that climate change is likely to result in significant changes to both wave climates and sea level. Traditionally, the effect of climate change on shoreline response has been assessed for sea level rise using the Bruun Rule, a simplistic cross-shore equation which can neither account for changes in wave climate or variations in longshore sediment transport resulting from sea level rise. As part of a Masters Research project Chris Huxley developed a methodology capable of addressing this issue in the form of a coupled cross/longshore shoreline response model. This dissertation outlines research completed to develop the modelling approach, including a case study assessment for Wooli Beach in Northern NSW, Australia. The case study assessment provides insight into to the effect that changes in wave climate may have on our coastline compared with sea level rise alone. Additionally, the results highlight the non-uniform shoreline response to climate change likely to impact open coast littoral drift dominated beaches. ····· 10361133475

Inversion of electromagnetic data requires a number of repeated solves of the mathematical/numerical model in an iteration process. The computational efficiency of the solver will therefore have great impact of the computational efficiency of the inversion. Various types of solvers, like finite difference, finite element, integral equation (IE), and hybrid methods, have been applied. The different types of methods have different computational advantages and disadvantages. With rigorous IE, a dense-matrix problem must be solved. For problems involving many grid cells in the target region, a huge computational effort is then needed.The main focus of this thesis is to develop and analyze a fast and accurate hybrid method, simplified IE (SIE) modeling, for modeling of electromagnetic scattering from an underground target. The method consists of solving a finite volume problem in a localized region containing the target, and using the IE method to obtain the field outside that region.

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Establishing the presence of `life-like emergent phenomena` is a major goal of simulation based artificial life (ALife) studies. This book presents an abstract algorithmic framework towards this goal. Presented framework is used to study observational processes by which time-varying entities are identified and their behaviour is observed to uncover higher-level emergent phenomena. Observations are formalized as algorithmic transformations from the underlying dynamic structure of the model universe to a set of abstract components needed to establish the presence of emergent phenomena. Observability of evolutionary dynamics is used as a defining characteristic to infer the emergence of life in any ALife model. Computational complexity theoretic analysis of the problem of observability provides insights for an algorithmic realization of the presented framework for an automated discovery of life-like phenomena during model simulations. Anyone interested in the field of ALife and its operational processes would find this work useful. It should be of special interest to researchers, who aim to programmatically discover emergent properties in their models using simulations based studies. ····· 10361132900

In this regard, we study several problems and establish exponential, polynomial and general decay rate results. The decay results are established in the absence, as well as in the presence of a source term. This thesis contains five chapters. In Chapter 1, we discuss the properties and significance of viscoelastic materials and we end the chapter by reviewing some literatures related to our problems. In Chapter 2, we present some principal concepts, some theorems on Sobolev embeddings and some lemmas which are of essential use in the proofs of our results. In Chapter 3, we study the asymptotic behaviors of solution of a viscoelastic problem when the relaxation function is decaying exponentially in the presence of a source term. In this regard, we establish a decay result which depends on the behavior of the external force. The case when the relaxation function is decaying polynomially in the absence of a source term is treated in Chapter 4. A general decay result for the finite history case is studied in the last chapter. ····· 10361132891

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray A common problem in microarray cancer studies is how to identify and select the most informative marker genes whose expression levels are predictive of clinical or other outcomes of interest. 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.
