Environmental Visualisation
50,99 € *
ggf. zzgl. Versand

Environmental visualisation is an emerging topic in the field of information visualisation. It is fast gaining importance because natural environments are constantly being subjected to complex interactions between the physical world and human impacts. Natural environments are valued because of their pristine wilderness appearances, and human interventions normally seek to be in sympathy with the aesthetics of natural environments wherever possible. Visualisation can be used to show the visual impact of changes on a landscape. Visualisation can be used to structure information in ways which highlight interests of users, rather than simply providing raw data. In seeking to manage natural environments, it is desirable to model and understand these complex interactions in order to compare the outcomes when different management scenarios are applied. To achieve this, environmental visualisations are valuable.

Handwritten Digit Reconition

Although every person has different writing style so it is very difficult for machine to recognize these characters. So, lots of researcher did a lot of work in this area and still going on to make it better. Image processing is an interesting and widely used field in the research area. Handwritten digit recognition is a sub module of the image processing. Although lots of research has been done so for in this field and continues. This paper suggested a novel approach of off-line handwritten digit recognition. The paper classified the digits into four regions: the left part, right part, upper part and lower part. In these four parts the images are identified on the basis of curve. The curve of a left part image is converted into pixels and as well as rest of all parts. Then these pixels are compared through decision tree and the result of comparison describes the format of digit. This application should help in zip code recognition, bank´s cheque number recognition.

Ranking of Classifiers Using Active Meta Learning
38,99 € *
ggf. zzgl. Versand

In Classification, Model Selection is one of the critical issues as different models from different categories are available. To select the best model for any given data set is a challenging task. Meta Learning automates this task by acquiring knowledge from the past experience and stores this knowledge into database called Meta Knowledge Base. When new data set comes, stored knowledge can be used for proving ranking of the candidate algorithms. But one of the problems with Meta Learning is generation of Meta Examples as large number of candidate algorithms and data sets are available. To reduce the generation of Meta Examples into Meta Knowledge Base, Active Meta Learning can be used that reduces generation of Meta Examples and at the same time maintaining the performance of candidate algorithms. In this book, Ranking is provided using Active Meta Learning approach by considering Data set Characteristics.

Identificar competências em uma base textual não estruturada é uma tarefa árdua. Para tanto, precisamos de todo um embasamento teórico necessário para a utilização dos processos nos quais possam extrair conhecimento desta base, assim a Mineração de textos ou descoberta de conhecimento em textos (KDT) é necessária. Um fator importante no contexto é que a maioria das informações (mais de 80%) no mundo estão armazenadas neste formato textual, acredita-se que as técnicas de KDT possuam um grande valor comercial. Deste modo, neste livro, apresentamos um embasamento teórico necessário para a modelagem e proposta de desenvolvimento de uma aplicação para a busca e identificação de competências profissionais em currículos em processos de contratação, promoção ou formação de equipes. Para este fim, são utilizadas técnicas KDT, associadas ao uso de ontologias para representar cada um dos conceitos presentes nos currículos. A classificação prévia das competências por conceitos restringe o tamanho do contexto a ser pesquisado, proporcionando uma maior qualidade na seleção dos currículos, de acordo com as exigências da empresa na qual será efetuado o recrutamento.

Cloud Computing is the emerging field of computer science. The core idea of the field is to provide infrastructure, soft wares, utilities, and platforms online. But the main concern of the tittle is that each cloud has its own standard that´s why they not able to communicate with each other. Therefore, an agent is used to perform interoperability and portability, because they are interoperable by default as per Foundation of Physical Agent(FIPA). Hence increase the scope of Cloud User in prospective of best services and avoid inconvenience.

Real-Time C++
53,99 € *
ggf. zzgl. Versand

With this book, Christopher Kormanyos delivers a highly practical guide to programming real-time embedded microcontroller systems in C++. It is divided into three parts plus several appendices. Part I provides a foundation for real-time C++ by covering language technologies, including object-oriented methods, template programming and optimization. Next, part II presents detailed descriptions of a variety of C++ components that are widely used in microcontroller programming. It details some of C++´s most powerful language elements, such as class types, templates and the STL, to develop components for microcontroller register access, low-level drivers, custom memory management, embedded containers, multitasking, etc. Finally, part III describes mathematical methods and generic utilities that can be employed to solve recurring problems in real-time C++. The appendices include a brief C++ language tutorial, information on the real-time C++ development environment and instructions for building GNU GCC cross-compilers and a microcontroller circuit. For this third edition, the most recent specification of C++17 in ISO/IEC 14882:2017 is used throughout the text. Several sections on new C++17 functionality have been added, and various others reworked to reflect changes in the standard. Also several new sample projects are introduced and existing ones extended, and various user suggestions have been incorporated. To facilitate portability, no libraries other than those specified in the language standard itself are used. Efficiency is always in focus and numerous examples are backed up with real-time performance measurements and size analyses that quantify the true costs of the code down to the very last byte and microsecond. The target audience of this book mainly consists of students and professionals interested in real-time C++. Readers should be familiar with C or another programming language and will benefit most if they have had some previous experience with microcontroller electronics and the performance and size issues prevalent in embedded systems programming.
