für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray One of the best known general techniques for developing of the algorithms is the Backtracking method. It seeks to eliminate the generation of all possibilities in order to get the result. The Backtracking method can be applied to those problems for which the solution can be represented as a vector whose elements take values in some finite sets and who meet certain internal conditions. In the Backtracking method, the vector elements are expressed one at a time, assigning a value to a component will be done only after values have been assigned to all its previous components, and no incompatibilities exist between these values. Classical problems solved by this method are: queens problem, Cartesian product generation, the generation of combinations, the 0-1 knapsack problem. The book is structured into 7 chapters and provides the solutions to a number of 19 classical problems by using versions of the backtracking algorithm. Most of the paragraphs are followed by a section with solved exercises and problems. ····· 1036120976
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray IT-Governance has a major impact not only on IT management but also and foremost in the Enterprises performance and control. Business uses IT agility, flexibility and innovation to pursue its objectives and to sustain its strategy. However being it more critical to the business, compliance forces IT on the opposite way of predictability, stability and regulations. Adding the current economical environment and the fact that most of the times IT departments are considered cost centres, IT-Governance decisions become more important and critical. This research intends to provide an answer to IT-Governance requirements using Data Driven Decision Support Systems based on dimensional models. To address this research opportunity we have considered IT-Governance research (Peter Weill), best practises (ITIL), Body of Knowledge (PMBOK) and frameworks (COBIT). Key IT-Governance processes (Change Management, Incident Management, Project Development and Service Desk Management) were studied and key process stakeholders were interviewed. Based on the facts gathered, dimensional models (data marts) were modelled and developed to answer to key improvement requirements on each IT-Governance process. ····· 1036120938

Deep brain stimulation employ the use of high electric field to stimulate some brain centers. The final position of the electrodes in the brain is specified by the aid of CT and MRI scans for the patient`s head before and after the operation. A study of electric field distribution in the brain is required to interpret and improve the action of DBS. In this master thesis project, Voreen was extended to visualize a multimodal volume of the CT and MR images. The MR volume was segmented to extract the brain from the skull in T1 weighted images. Some image processing techniques were developed to enhance the contrast of CT and MR images. In order to stimulate electric field in the brain, the neurologists are allowed to design and position the electrodes in the reconstructed volume. The electrodes and some pre-modeled electric fields can be visualized in the reconstructed volume and the slice views. A mesh generator was developed using delaunay tetrahedralization. ····· 1036120645
für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In literature one can find numerous works on the subject of schema matching and integration. Under normal circumstances the methods employed are ideal for matching two schemas. But with the Web scale data sources availability, these techniques need to be enhanced. Querying schemas over web requires more robust and performance oriented techniques which have the capacity to cope with the large scale scenarios, where hundreds and thousands of schemas need to be matched for integration or data exchange. For a single query on the web, hundreds of schemas in the subject domain need to be scrutinized, to get the right information stored against them. The dynamic nature of web makes the scenario very difficult to comprehend by humans as well as software systems, for retrieval of good results. The work presented in this book is motivated by these large scale schema matching and integration applications. The book gives a detail explanation of research done in this domain. A hybrid approach utilizing tree mining technique is explained, to tackle the large scale scenario. Further, the same tree mining algorithm is extended to compute complex schema matching. ····· 1036120542

The proposed CBM method gives the geometric definition for all English Alphanumeric characters. All characters recognized by using arc (s), radius (radii) and center of a circle. Any character is recognized by the presence or absence of arc (s), radius (radii) and center. Thus our proposed feature vector consists of eight radii, eight arcs and a center of a character. From CBM we get different index values for distinct characters and using this value any alphanumeric characters can be recognized. The overall efficiency of the CBM is satisfactory to recognize the characters at the specified font. It has been found from the experimental results that the accuracy rate is approximately 96% for all types of character recognition. ····· 1036120472

Estimation is the basis for planning therefore, having a reliable way of estimating effort needed to perform the tasks is a must for a reliable project plan. Already in 1987, Samson, Nevill and Dugard, showed that there is a strong and direct influence of formal specification metrics onto the effort needed for implementation. Since then, there has been some progress in various aspects of formal specifications the introduction of specification slicing methods, slice-based specification metrics, and methods for visualization of specifications has opened new ways for measuring properties of specifications with more metrics. Nevertheless, there hasn t been much progress in the field of cost estimation using recent achievements of formal specifications. The main focus in this work is to examine if there is a correlation between formal Z specification measures and implementation related measures. In concise, this work tries to explain the correlation between the measures in specifications and code. ····· 1036120423

The revolution of information technology has led to the emergence of electronic interaction that involves machines to support and facilitate humans` interaction. Though the research on electronic interaction has achieved large advances in the last decades, there are still critical and challenging problems especially with regards to semantic interaction. Namely, little attention has been paid to devise technology that reflects humans natural interaction. Humans need a smart technology that reasons and acts on behalf of them and, consequently, minimize their effort. In order to reflect the human natural interaction, one core problem to face is the semantics in human interaction. In this work, we study the semantics enabled interaction. Our ultimate goal is to develop a technology that maximizes the reflection of human natural way of interacting. We present a theory of the semantic enabled interaction by capturing its definition, procedure and semantics. ····· 1036120373
für 49.41€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Automata-theoretic tools have been deeply utilized in literature for studying algebraic matters, in particular free monoids and free groups. In this book we propose to study finitely generated submonoids of free monoids and finitely generated subgroups of free groups, and their intersection. Free monoids play an important role in combinatorics on words and in formal language theory. The study of submonoids of free monoids has been deepened by using combinatorial and automata methods in the setting of the theory of variable-length codes, started by M.P.Schützenberger. We investigate the intersection of two finitely generated submonoids of the free monoid on a finite alphabet by using an automata-theoretic approach. For what concerns free groups, several open problems have been solved and moreover several algorithms concerning group`s problems have been optimized using automata. We focus on algorithms constructing particular bases for a subgroup of a free group and in particular strongly reduced Nielsen bases. Using inverse automata we furnish two algorithms for the construction of a strongly Nielsen basis for a finitely generated subgroup. ····· 1036120250

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Spreadsheets play an important role in software organizations: they are not only used to define sheets containing data and formulas, but also to collect information from different systems, to perform operations to enrich or simplify data, etc. Unfortunately, spreadsheet systems provide poor support for modularity, abstraction, and transformation, thus making the maintenance of spreadsheets a complex and error-prone task. An emerging solution to handle complex software systems is model-driven engineering. Its basic principle is to consider models as first class entities and to classify any software artifact as either a model or a model instance. In our work, we adapted to spreadsheets several techniques that are inspired by model-driven approaches to generic software systems. In fact, most spreadsheets lack a proper specification or a model. Using reverse engineering techniques we are able to derive various models from legacy spreadsheets: they can be used for several improvements, namely refactoring, safe evolution, migration or even generation of edit assistance. The techniques presented in this book have been integrated in HaExcel, a framework to improve spreadsheet productivity. ····· 1036120157

This book introduce the idea of using the concept of fractal dimension spectrum for describing, discriminating and classifying different visual textures. Two methods for estimating the fractal dimension spectra are proposed the first method is the modified binarization method and the second is the traditional box counting method. A testing procedure was conducted to evaluate the degree of sensitivity for each kind of fractal dimension spectrum to the visual variation of the different textures. It has been shown a satisfactory results for the usage of fractal dimension spectra as textural discriminating criteria. The proposed classification methods were applied on two important set of images the first set consists of remote sensing images, and the second set consists of breast tumors images. The higher recognition accuracy in the first set of textures images was (100%), while in the second set was (98.8%). ····· 1036120039

Thus, a heuristic approach (Neural Network Model) is often the only viable alternative. Neural Network Models offer the most unified approach to building truly intelligent systems which can provide good optimal solution for many applications. In this work we propose a hybrid (Kalkoh) neural network algorithm which is being used to model and solve the continuous stirred tank mixer (CSTM) problem. The hybrid algorithm is robust and converges fast without being trapped into a local minimal as is the case with the popular back-propagation neural network.

Due to the gap between modeling and programming artifacts, refactoring efforts soon become duplicate and considerably expensive. In this context, currently used tool support, in special Round-Trip Engineering (RTE) tools, fails to fully automate evolution tasks. Consequently, most projects discard object models early in the life cycle, adhering to code-driven approaches. This work proposes a formal approach to consistently refactor object models and object-oriented programs of a system in a model-driven manner. Model refactoring is backed by formal laws of modeling, which are guaranteed to be semantics preserving. Each refactoring, a composition of laws, applicable to an object model, is associated with a semi-automatic sequence of applications of laws of programming, called strategy. Strategies are applied by relying on a specific conformance relationship between object models and programs, which must fulfill a specific degree of confinement. ····· 1036118700
