Software communities are striving for techniques and approaches that could improve developer s productivity, reduce time-to-market, excellent performance and produce systems that are flexible, scalable, secure, and robust. Only possible solution of this problem is component-based software engineering, which has generated tremendous interest in software communities. Unfortunately, the quality attributes of the final component based system, such as its performance, scalability or reliability, are not easy to determine. For this reasons, the component-based approach, is difficult to utilize in domains in which quality attributes are of primary concern. This dissertation proposes quality model for CBSD that defines a set of quality attributes for the effective evaluation of COTS components. Further, this dissertation also suggests few necessary guidelines and proposes some relevant metrics applicable to it, which after proper quantification and validation may help guiding risk and quality management of CBSD. This dissertation may help the research scholar s software, practitioners and students in better understanding of more relevant metrics applicable to quality management of CBSD
This book provides an overview of state-of-the-art uncertainty quantification (UQ) methodologies and applications, and covers a wide range of current research, future challenges and applications in various domains, such as aerospace and mechanical applications, structure health and seismic hazard, electromagnetic energy (its impact on systems and humans) and global environmental state change. Written by leading international experts from different fields, the book demonstrates the unifying property of UQ theme that can be profitably adopted to solve problems of different domains. The collection in one place of different methodologies for different applications has the great value of stimulating the cross-fertilization and alleviate the language barrier among areas sharing a common background of mathematical modeling for problem solution. The book is designed for researchers, professionals and graduate students interested in quantitatively assessing the effects of uncertainties in their fields of application. The contents build upon the workshop "Uncertainty Modeling for Engineering Applications" (UMEMA 2017), held in Torino, Italy in November 2017.
This book presents a first comprehensive typological analysis of noun phrases in Australian languages, covering the domains of classification, qualification, quantification, determination and constituency. The analysis is based on a representative sample of 100 languages. Among other points, the results call into question the classic idea that Australian languages tend to lack phrasal structures in the nominal domain, with over two thirds of the languages showing evidence for phrasehood. Moreover, it is argued that it may be more interesting to typologise languages on the basis of where and how they allow phrasal structure, rather than on the basis of a yes-no answer to the question of constituency. The analysis also shows that a determiner slot can be identified in about half of the languages, even though they generally lack 'classic' determiner features like obligatory use in particular contexts or a restriction to one determiner per NP. Special attention is given to elements, which can be used both inside and beyond determiner slots, demonstrating how part of speech and functional structure do not always align. The book is of interest to researchers documenting Australian languages, as well as to typologists and theorists.
Presently some on-line vibration monitoring methods was used as an in-flight diagnostic and trend monitoring device. But verylittle work has been accomplished on the detection and quantification of combined gear damages and bearing faults in a bearing-rotor-gear transmission system. Vibrations caused by the combined damages in gears and bearing usually can not be identified readily without special procedure applied to the vibration signature. In this thesis, under a variety operating cases, vibration signature due to the combined damage between the outerrace of bearing and the teeth of gear were examined in both timeand frequency domains for identification purposes. Joint time-frequency analysis such as the Wigner-Ville Distribution (WVD) was used in detecting and identifying various types of gear and bearing damage. The modified Poincare Maps based on chaotic vibration were also successfully applied in analyzing the vibrationfrom gear and bearing damages. The objective of this work is to develop an on-line Health Monitoring system to detect faults ingear and bearing. Considerable success has been achieved in thiswork to identify faults in both bearing and gear components.
Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Statistical relational learning (SRL) is a subdiscipline of artificial intelligence that is concerned with models of domains that exhibit both uncertainty (which can be dealt with using statistical methods) and complex, relational structure. Typically, the knowledge representation formalisms developed in SRL use (a subset of) first-order logic to describe relational properties of a domain in a general manner (universal quantification) and draw upon probabilistic graphical models (such as Bayesian networks or Markov networks) to model the uncertainty, some also build upon the methods of inductive logic programming. Significant contributions to the field have been made since the late 1990s.

Focus particles--'even, only, also, merely'--play an important role in English in various syntactic and semantic domains such as coordination, focusing, emphatic reflexives, concessive constructions, and quantification. The syntactic properties of these expressions pose numerous problems for current syntactic frameworks and the highly context-dependent and subjective nature of their meaning presents a challenge for semantic theories. 'The Meaning of Focus Particles' presents a comprehensive analysis of the syntax, meaning, and use of focus particles and related function words. It combines an in-depth analysis of English with a comparative study of many other languages. Ekkehard Konig also provides a historical perspective on focus particles by examining their diachronic sources and the relevant process of grammaticalization. 'The Meaning of Focus Particles' will appeal to philosophers of language and semanticists of all persuasions. Specialistsin English will find a new approach to the syntactic and semantic properties of a class of adverbs' whose analysis until now has been problematic. The comparative aspect is of real interest to language typologists, since this is the first time that a cross-linguistic typology of this pragmatic-semantic area has been proposed. For the historical linguist there are detailed discussions of grammaticalization processes, of correlations between historical sources and targets in focus particle development, and of the pragmatic-semantic interaction in historical change.
The significant advances witnessed over the last years in the broad field of linguistic variation testify to a growing convergence between sociolinguistic approaches and the somewhat older historical and comparative research traditions. Particularly within cognitive and functional linguistics, the evolution towards a maximally dynamic approach to language goes hand in hand with a renewed interest in corpus research and quantitative methods of analysis. Many researchers feel that only in this way one can do justice to the complex interaction of forces and factors involved in linguistic variability, both synchronically and diachronically. The contributions to the present volume illustrate the ongoing evolution of the field. By bringing together a series of analyses that rely on extensive corpuses to shed light on sociolinguistic, historical, and comparative forms of variation, the volume highlights the interaction between these subfields. Most of the contributions go back to talks presented at the meeting of the Societas Linguistica Europaea held in Leuven in 2001. The volume starts with a global typological view on the sociolinguistic landscape of Europe offered by Peter Auer. It is followed by a methodological proposal for measuring phonetic similarity between dialects designed by Paul Heggarty, April McMahon, and Robert McMahon. Various papers deal with specific phenomena of socially and conceptually driven variation within a single language. For Dutch, José Tummers, Dirk Speelman, and Dirk Geeraerts analyze inflectional variation in Belgian and Netherlandic Dutch, Reinhild Vandekerckhove focuses on interdialectal convergence between West-Flemish urban dialects, and Arjan van Leuvensteijn studies competing forms of address in the 17th century Dutch standard variety. The cultural and conceptual dimension is also present in the diachronic lexicosemantic explorations presented by Heli Tissari, Clara Molina, and Caroline Gevaert for English expressions referring to the experiential domains of love, sorrow and anger, respectively: the history of words is systematically linked up with the images they convey and the evolving conceptualizations they reveal. The papers by Heide Wegener and by Marcin Kilarski and Grzegorz Krynicki constitute a plea against arbitrariness of alternations at the level of nominal morphology: dealing with marked plural forms in German, and with gender assignment to English loanwords in the Scandinavian languages, respectively, their distributional accounts bring into the picture a variety of motivating factors. The four cross-linguistic studies that close the volume focus on the differing ways in which even closely related languages exploit parallel morphosyntactic patterns. They share the same methodological concern for combining rigorous parametrization and quantification with conceptual and discourse-functional explanations. While Griet Beheydt and Katleen Van den Steen confront the use of formally defined competing constructions in two Germanic and two Romance languages, respectively, Torsten Leuschner as well as Gisela Harras and Kirsten Proost analyze how a particular speaker's attitude is expressed differently in various Germanic languages.
