Speech disorders, especially hypernasality, are common in children with cleft lip and palate. In order to simplify the diagnosis during the speech therapy of these patients an automatic non-invasive way to measure hypernasality is desirable. In this context, the author analyzes approaches to the detection of hypernasal speech. The focus lies on examining the fitness of several features for that purpose. These include pronunciation features computed from phoneme confusion probabilities, prosodic features, features based on the Teager Energy operator, and Mel Frequency Cepstral Coefficients. The extraction process of each of these features is described as well as the classification system in which they are tested. Finally, experimental...

The use of local likelihood methods (Tibshirani and Hastie, 1987; Loader, 1996) in the presence of interval-censored or aggregated data leads to a natural consideration of an EM-type strategy, or a local EM algorithm. We consider local EM to analyze point process data that are either interval-censored or aggregated into counts. We present the formulation of local EM algorithms to estimate density, intensity and risk and their implementations using piecewise constant functions. It is shown that the use of the piecewise constant function at the E-step explicitly results in an iteration that involves an expectation, maximization and smoothing step, or an EMS algorithm considered in Silverman et al. (1990). Consequently, we reveal a...

Thema des vorliegenden Buches ist die Analyse von Softwareprozess-Modellen. Solche Modelle bilden die Grundlage prozessgesteuerter Softwareenwicklungs-Umgebungen (PSEU). Diese unterstutzen die Durchfuhrung insbesondere grosser und raumlich verteilter Softwareprojekte, indem sie die Arbeit vieler Softwareentwickler geeignet koordinieren. Der Korrektheit eines Softwareprozess-Modells kommt ein hohes Mass an Bedeutung zu. Werden Fehler (d.h. Inkonsistenzen zwischen dem erwunschten Prozess und seinem Modell) erst zur Laufzeit eines konkreten, raumlich weit verteilten Projekts entdeckt, ist ihre Korrektur haufig mit grossen Schwierigkeiten verbunden. Daher sollten geeignete Editier-, Analyse- und Simulations-Werkzeuge zur Verfugung stehen, um...

This study deals with the evaluation of performance data from the TTM - Test Traffic Measurement project in the New Projects Group at the RIPE NCC. Here we introduce new methods and tools to help draw conclusions on the performance when comparing IP4 and IPv6 delay data. The concepts proposed in this thesis will become the basis of new TTM services, providing quality assurance tools for backbone networks. An analysis of the current TTM network was carried out using these new approaches. Finally, we present an account on the development of a tunnel detection tool. The tool detects IPv4 tunnels in IPv6 networks and has already been introduced as a new RIPE NCC service. Данное издание не является...

Clinical trials often involve multiple endpoints that are clinically meaningful to determine efficacy and safety of the investigational medicinal product. These multiple outcomes are often measured over scheduled and/or unscheduled visits which add complexity when analyzing these types of data. This book is developed specifically to deal with multiple longitudinal outcomes in the framework of generalized estimating equations and their post-hoc multiplicity adjustment for the control of familywise error rate. The book covers a recent development and its extension of quasi-least squares to the application in clinical trials for the analysis of single and multiple longitudinal outcomes. A user-written SAS software with its complete code and...

To analyze an algorithm is to determine the amount of resources (such as time and storage) necessary to execute it. Most algorithms are designed to work with inputs of arbitrary length. Usually the efficiency or complexity of an algorithm is stated as a function relating the input length to the number of steps (time complexity) or storage locations (space complexity). Algorithm analysis is an important part of a broader computational complexity theory, which provides theoretical estimates for the resources needed by any algorithm which solves a given computational problem. These estimates provide an insight into reasonable directions of search for efficient algorithms. In theoretical analysis of algorithms it is common to estimate their...

With the introduction of computers, the analytical stereoplotter became a popular machine of choice photogrammetry in the late 1960’s to 1970’s. A stereoplotter is an instrument that uses stereo photographs to determine elevations for the purpose of creating contours on topographic maps. Computers bought the capability to execute more precise calculations that ensure additional accurate output instead of approximations. This innovation also allowed a shift to a digital format rather than paper. Analytical stereoplotters edged out their analog predecessors and became the primary method of acquiring elevation data from stereo photographs. Данное издание не является оригинальным. Книга...

The analytical engine, an important step in the history of computers, was the design of a mechanical general-purpose computer by the British mathematician Charles Babbage. In its logical design the machine was essentially modern, anticipating the first completed general-purpose computers by about 100 years. It was first described in 1837. Babbage continued to refine the design until his death in 1871. Because of the complexity of the machine, the lack of project management science, the expense of its construction, and the difficulty of assessing its value by Parliament relative to other projects being lobbied for, the engine was never built. Some have said that the technological limitations of the time were a further obstacle to the...

High Quality Content by WIKIPEDIA articles! In complex analysis, a branch of mathematics, analytic continuation is a technique to extend the domain of definition of a given analytic function. Analytic continuation often succeeds in defining further values of a function, for example in a new region where an infinite series representation in terms of which it is initially defined becomes divergent.

Software Product Lines (SPLs) are sets of software systems that share a common base of features and satisfy the needs of specific market segments. SPLs are developed from a common architecture and share a set of reusable artifacts (designed for a specific domain). Among the main activities in the life cycle of a SPL is the management of variations in all the artifacts that belongs to it. Particularly, the choice of programming techniques that enable variability in implementation artifacts is an activity that deserves much attention. The choice of which technique to use in order to deal with variations in the implementation artifacts of a SPL can result in significant impacts on the quality of these artifacts and also in the resulting...

In mathematics, specifically geometry, an analytic variety is defined locally as the set of common solutions of several equations involving analytic functions. It is analogous to the included concept of complex algebraic variety, and any complex manifold is an analytic variety. Since algebraic varieties may have singular points, not all analytic varieties are complex manifolds. An Analytic variety is also called real or complex analytic set.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematics, an analytic function is a function that is locally given by a convergent power series. Analytic functions can be thought of as a bridge between polynomials and general functions. There exist both real analytic functions and complex analytic functions, categories that are similar in some ways, but different in others. Functions of each type are infinitely differentiable, but complex analytic functions exhibit properties that do not hold generally for real analytic functions. A function is analytic if and only if it is equal to its Taylor series in some neighborhood of every point. Данное...

Availability is a key feature in the fault tolerant distributed systems, like clusters, and it can be achieved by using failover techniques. For cluster availability, simplified strategies such as cold backup and warm backup are used by spare resources. High cost can be a drawback for using many stand-by computers in a large cluster system in order to achieve predefined level of availability. Another substitute solution for failure detection and recovery is the hot backup, even it is hard to make a decision on which computer the task of failure computer is executed while maintaining the load balance. Dynamic monitoring facilities and central scheduling are the usual solutions for this. In practice, the above solution turned out to be a...

In this book we are interested in manifolds with cusp like singularities that are in between the cases of cylindrical end and of hyperbolic cusp. More precisely, we study the Laplace operator acting on p-forms, defined on an n-dimensional manifold with generalized cusp. Such a manifold consists of a compact piece and a noncompact one. The noncompact piece is isometric to the generalized cusp. A generalized cusp is an n-dimensional noncompact manifold equipped with a parameter dependent warped product metric. When the positive parameter goes to zero, the cusp becomes a cylinder, and when it goes to infinity, it could be thought of as approaching the n-dimensional hyperbolic cusp. In such a manifold we construct the generalized eigenforms...

The book is devoted to non-commutative analysis over Cayley-Dickson algebras and its applications to partial differential equations. In the first chapter super-differentiability of functions is described on regions of the real Cayley-Dickson algebra. The non-commutative analog of the Cauchy integral as well as criteria for functions of a Cayley-Dickson variable to be analytic are exposed. Among the main results we have the Cayley- Dickson algebras analogs of Caychy's theorem, Hurtwitz', argument principle, Mittag-Leffler's, Rouche's and Weierstrass' theorems, etc. In the second chapter the theory of meromorphic functions of the Cayley-Dickson variables is presented. Their properties and methods of calculations of their residues and...

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. In mathematical analysis, an analytical proof is a proof of a theorem in analysis that only makes use of methods from analysis, and which does not make use of results from geometry. The term was first used by Bernard Bolzano, who first provided a non-analytic proof of his intermediate value theorem and then, several years later provided proof of the theorem which was free from intuitions concerning lines crossing each other at a point and so he felt happy calling analytic.

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. The simplest definition of analytics is "the science of analysis". A simple and practical definition, however, would be how an entity (i.e., business) arrives at an optimal or realistic decision based on existing data. Business managers may choose to make decisions based on past experiences or rules of thumb, or there might be other qualitative aspects to decision making; but unless there are data involved in the process, it would not be considered analytics.
