Several methods have been proposed for making this three levels decision and most of them need Speech Activity Detection (SAD). In this study, we propose the Estimated Degree of Noise (EDON) to adjust the threshold of speech activity. To estimate the degree of noise, a function was previously prepared using the least-squares (LS) method, from the given (true) DON and the estimated parameter of DON. This parameter is obtained from the Auto-Correlation Function (ACF) of the noisy speech on a frame basis. Issues associated with this EDON for SAD approach are discussed, and experiments are done using the TIMIT database. Experimental result shows that using EDON improves the classification performance specially voiced and silent parts and the efficiency is compared with other existing published algorithms. ····· 10361147434
für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Relational databases are not well suited for representing and processing hierarchical data. Clever schemes are required to represent trees in the flat format of the relational model, as well as answering queries such as retrieving all nodes in a sub-tree, all nodes at a particular level and the nodes on the path from a node to one of its descendants. Some areas where hierarchical data needs to be stored and processed include XML data warehousing, organization chart in automation systems, bioinformatics and pyramidal games that require hierarchical data representation. In this book, a new method (Arya) is proposed to represent hierarchical data structures in relational database systems so that queries proved on trees can be executed efficiently. This method reshapes hierarchical data structures to non-hierarchical graphs using extra pointers to be accessed directly from each node to its ancestors. The cost for the gained performance is only a small increase in the space required for the representation of the original tree, which is significantly less than the used space by other methods. ····· 10361147388

In the current democracies, there is an increasing demand to bring citizens closer to the government and to improve delivery of government services. There is always pressure on the government to achieve its objective within the budget constraints, an effective E-governance solution seems to be the better way out by offering opportunities for governments to re-invent themselves & deliver services at reduced time to its various clients and Citizens (G2C), Business (G2B), Employee (G2E) and Government (G2G). Today, as citizens are becoming more and more conscious of their right to get the required services and as both the state and Central governments recognize the need to deliver faster and efficient services to the ordinary citizens, e-governance (or government `online`) has emerged as an effective instrument of administration.

Mediators are middleware in which a new layer is introduced between applications and data sources, so changes in either application layer or data sources layer will not affect the other. The mediation layer adds value to systems such as data conversion, integration, and presentation. Before data can be integrated, it must be found: a simple solution to this is to maintain a repository for the schemas of the data sources. However, this approach affects the reliability and scalability of the system.

In this book, the effect of social network structure, position, ties and information and communication technologies (ICT) use on performance attitudes of knowledge-intensive workers in dispersed occupational communities is investigated. Based on social network theories of strength of weak ties and structural holes, and the social influence model of technology use, a theoretical framework is developed. A validated and reliable data collection instrument is also developed. Network measures of degree centrality, density, structural holes (constraint and efficiency), tie strength and tie diversity are applied for exploring the association with ICT use and performance from a sample of 110 knowledge workers. Empirical results suggest that network structure, position and ties of knowledge workers play a crucial role in individual performance and ICT use.

Camera calibration can be accomplished using one of two strategies. The first is off-line calibration which is often used when the camera is stationary during the setup operation. This however reduces the flexibility of using the camera. Alternatively, the camera may be calibrated during the normal operation of the setup. This strategy is called auto-calibration. To achieve greatest flexibility, this work focuses on the auto-calibration strategy. Once the camera is calibrated, it is possible to compute a metric reconstruction from the image sequence. As a result of the flexibility of this strategy, a 3D scene can be imaged from multiple views by a hand-held camera, which can be moving freely without special setup or hardware configuration. Several methods for solving the camera auto-calibration are discussed and implemented in this thesis. The thesis also studies this problem when the camera internal parameters are allowed to change, as the case with a zooming image sequence. ····· 10361147114

für 44.10€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray This comprehensive text shows the effectiveness of using mobile sinks in obtaining potential energy savings for the sensors in wireless sensor networks. The entire sensor network is divided into two layers: the resource-constrained sensor nodes constituting the lower layer and a mobile ad hoc network of resource-rich sinks forming the upper layer. Each sink is responsible for monitoring and data collection from a particular cluster of sensors. A sink moves to the vicinity of the sensor nodes - in a cluster - to collect data and exchanges the collected data with peer mobile sinks. The data can be transferred to the base station through multi-hop sink-to-sink data propagation and the energy loss incurred due to multi-hop data propagation in disseminating the data from a sensor to the control center is accounted to the sinks rather than sensors. This book also illustrates the scenarios, use just one mobile sink - where use of multiple mobile sinks becomes unaffordable - to reduce energy consumption in wireless sensor network. The lone mobile sink transfers the collected data to the base station directly. ····· 10361147040

In particular, we study two problems. The first problem is the multi-shift Vehicle Routing Problem (MSVRP) with overtime to meet around-the-clock demand. We use insertion to create the initial routes and then use tabu search to improve the routes. We show that our algorithm can find high-quality solutions for very large problems. The second problem is a multi-city resource allocation model to distribute the medical supplies in order to minimize the total number of fatalities in an infectious disease outbreak. We consider the problem with uncertainty in the initial number of cases and transmission rate, and build a two-stage stochastic programming model. To solve instances of realistic size we use a heuristic based on Benders decomposition. Finally, we use sample average approximation (SAA) to get confidence intervals on the optimal solution. We illustrate the use of the model and the solution technique in planning an emergency response to a hypothetic national smallpox outbreak. Computations show that the algorithm is efficient and can obtain near-optimal solution. ····· 10361147008

Usability is acted with end-user by an interaction between user and the system. This interaction is maintained by user interface. But to the software engineer, usability is just one of the many aspects that must be taken into account in the development process and most of the case if it is an explicit interest then is considered if time permits.Moreover, there is a trend to consider usability the responsibility of somebody else. Typically, usability is still considered as a test activity rather than a product design activity.

für 61.20€ kaufen ···· Rheinberg-Buch.de - Bücher, eBooks, DVD & Blu-ray Reconstructing a metric structure of a scene from images has been one of the important topics in computer vision. In this book, we focus on a simple diagonal rank-deficient form of a 2D metric invariant, a conic dual to the circular points. By manipulating image features to constrain the simple form algebraically, the metric reconstruction can be achieved. We start from second order curves such as concentric circles or confocal conics to be used as basic features. By simply subtracting them, affine and metric properties of a plane are recovered. The geometric meanings of the resulting subtraction matrices are also investigated. The idea of algebraically manipulating features extend to an ``addition method`` using human recognizable features such as a rectangle. Its parallelism and orthogonality enables us to obtain information of the scene structure. As a generalization, we propose a framework to unify the geometric constraints used in camera calibration and in metric reconstruction. We show that scene constraints can be converted into constraints of cameras, and that a flexible algorithm to metric-reconstruct scenes from images can be developed in the proposed unified framework. ····· 10361146850
