für 53.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray In service oriented world, mitigating human intervention in name resolution, service registration and discovery, resource storage and access etc. has always been a hot research topic. Peer-to-peer systems give an impetus to achieving these tasks in distributed way with no centralized single point of failure. Accomplishing these tasks becomes more challenging in peer-to-peer ad hoc networks where dynamism is inherited trait. This work is an effort to achieving auto-organization including automatic IP assignment, domain name resolution, service discovery and lookup in p2p ad hoc networks. We employ Scope a p2p social networking prototype on ad hoc networks developed under a European ITEA project, as a case study for this work. We prototype a system, which provides domain name resolution, bootstrapping (super) node discovery, service discovery and registration in local ad hoc networks. We propose and develop service lookup system that works in global settings. Our solution for lookup is based on One Hop DHT for ad hoc networks giving query result in a single routing hop with minimum possible network traffic. The simulation results for lookup show the effectiveness of our approach. ····· 1036121008
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book tries to connect the successful implementation and operation of the ERP (Enterprise Resource Planning) information systems with people and their characteristics. It examines the human factors that influence ERP user satisfaction. The key findings that were found when analysing the data were that none of the human socio-demographic characteristics do influence ERP user satisfaction. In the current survey was found that perceived usefulness and self-efficacy are the key directors of the ERP user satisfaction. Users that intent to use the ERP system and feel that they are able enough to correspond to whatever it will arise while using the ERP system, these users are the most satisfied. A discussion takes place about how the companies should handle this situation in order to develop the prerequisites for increasing the user satisfaction and the productivity accordingly. Such recommendations should be taking into account from top management in order for organizations to increase their human capital, increase the return on investment (that is made on ERP information systems) and gain competitive advantage. ····· 1036120960

In many applications, the size of the data that needs to be clustered is much more than what can be processed at a single site. Further, the data to be clustered could be inherently distributed. The increasing demand to scale up to these massive data sets which are inherently distributed over networks with limited bandwidth and computational resources has led to methods for parallel and distributed data clustering. In this book, we present a cohesive framework for cluster identification and outlier detection for distributed data. The data is either distributed originally because of its production at different locations or is distributed in order to gain a computational speed up. We use a parameter free clustering algorithm to cluster the data at local sites. ····· 1036120944

für 71.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This book investigates how data and information are transformed into knowledge that supports decision-making processes. The information revolution renders information a common product: it is easily supplied, accumulated, processed and managed. In recent years, the amount of data has been growing exponentially. Traditional methods of data analysis rely primarily on slower, more expensive manual investigation and analysis. These limitations make the traditional methods impractical. This book provides an alternative approach and presents a novel framework to advance data analysis through the knowledge discovery process. This work borrows ideas from related fields, such as Operations Research and Information Theory. Grounded in these disciplines and formal mathematical expressions, this work presents a comprehensive model and corresponding design tools. Last, this book enables a rigorous exploration of data analysis and knowledge discovery tools which provide a roadmap to better decision-making. ····· 1036120822

A personalized information filtering system must be able to tailor to current interests of the user and to adapt as they change over time. This research has proposed a content-based personal information system that learns the user preferences by analyzing the content of the document and building the user profile. The proposed filtering system monitors a stream of incoming documents to deliver only those matches the user profiles. This system is called RePLS an agent-based Reinforcement Profile Learning System with adaptive information filtering. The agent approach is used because of its autonomous and adaptive capabilities to perform the filtering. The core of this system is an improved term weighting method which is called Purity term weighting to measure the importance of the most suitable terms represented in each profile. The top selected terms are then used to filter the incoming documents to the learned user profiles. ····· 1036120812

There are many existing edge detection techniques but still many practical issue exists in this field. Edge is a set of those pixels whose grey have step change/ rooftop change and it exists between objects & its background, onject & object, region & region and between element & element. These edge detection techniques do not work well upon these images. Many edge detection algorithms are used to find boundaries in images. A significant problem with mammography is the variability of diagnosis among radiologist and computer aided diagnosis (CAD) methods that consistently highlight region on mammograms that may warn further examinations. One of the first step in CAD is the segmentation of the image into background and the breast. This has the advantage of further simplifying the processing of image (by eleminating the background) and also provides as a reference for the alignment of the views when two viewes are being compared. Knowledge of the breast edge also sometimes identifies large masses that have distorted the outline of the breast. ····· 1036120751

A generic data mediator provides uniform support for both XML and relational data with similar storage and retrieval efficiencies is produced by using existing efficient schema-oblivious mapping strategies XNode and SUXCENT and free of cost available technologies: MySQL, PHPMyAdmin and PHP classes. The key to mediator approach is storing and retrieving XML documents in a relational database, providing a user interface for XML manipulation, independent of proprietorship and without doing any modification in its basic structure. After the mediator`s implementation, the RDBMS becomes repository for both XML and Relational data simultaneously. The mediator has flexibility to add any proposed more efficient schema-oblivious XML mapping strategy as a new collection. The mediator can also be used as the benchmarking tool for the researchers to compare various schema-oblivious XML mapping strategies by adding a new collection. The comparative study of insertion, retrieval and query performance of these two types of mapping strategies is produced. ····· 1036120728

The current trend in this direction focus on representing the information needs of the user along with the query. This representation need to be automatic and transparent to the furthest extent possible. In this work the focus is on identifying and understanding the user intent: What motivated the user to perform a search on the web To this end, we apply machine learning models not requiring more information than the one provided by the very needs of the users, which in this work are represented by their queries. The knowledge and interpretation of this invaluable information can help search engines to obtain resources, especially relevant to users, and thus improve user satisfaction. By means of unsupervised learning techniques, which have been selected according to the context of the problem being solved, throughout this research work, we show that is not only possible to identify the user`s intents but that this process can be done automatically. ····· 1036120673

A buffered based implementation has been proposed which accept a stream of data form input port store the data into the buffer. The encryption technique operates on the data to generate the intermediate encrypted data stream through simulated hardware. Triangular Encoder deals with string / block as input and produces the string / block as output based on the XOR operation. The XOR operation is done on a fixed size data block, which is taken from the buffer storage. The number of iterations depends on the size of the block of data bits in the data stream. This encoder follows the principle of block cipher technique and symmetric in nature, hence decoding is done following the same procedure. The buffer can store the encrypted data also. This simulation gives the hardware definition/ RTL for buffer based encryption. ····· 1036120580

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Medical Data mining is the search for relationships and patterns within the medical datasets that could provide useful knowledge for effective clinical decisions. The medical data are usually multidimensional,and is presented by a large number of features. The inclusion of irrelevant, redundant and noisy features in the process model can result in poor predictive accuracy and increased computation. The success of the data mining technique is based on the selection of a small set of highly predictive attributes. Feature selection techniques extract informative features from medical databases to facilitate medical decision making in an effective and efficient way. The feature selection methods discussed, both Wrapper and Filter methods, use feature ranking methods to identify the informative and discriminatory features of the medical datasets, which greatly influence the predictive accuracy of the classifiers. There is a significant improvement in the sensitivity and specificity values which shows that the feature selection indeed improves the discriminating ability of the classifiers.
