Unified Access to Heterogeneous Resources in a Distributed Library Consortia Environment: Challenges and Opportunities
No full textLibrary consortia in today’s digital age are quite different from that of library networks in yester years. The main reason is that the resources that are shared in today’s consortia environment are predominantly in electronic form such as electronic journals and databases. Hence the technology and associated tools to support sharing the electronic resources are also important components for the success of any library consortia. It is essential that each participating libraries of a consortium is equipped with necessary and sufficient technology to support sharing the resources across. Unified access to heterogeneous resources is one of the greatest challenges that library consortia face. The paper looks at the unified access system to search heterogeneous resources in a distributed library environments. The paper discusses the challenges and opportunities of unified access systems by looking at some of the major international initiatives

Convenient and Efficient Microwave-Assisted Synthesis of a Methyl Derivative of the Fused Indoloquinoline Alkaloid Cryptosanguinolentine
No full textAn efficient synthesis of a methyl derivative of the indoloquinoline alkaloid cryptosanguinolentine based on microwave-assisted reactions is described. The microwave-assisted synthesis of an intermediate 4-hydroxy-2-methylquinoline yielded 86% of the desired product and other intermediates prepared yielded high % of products in shorter reaction times, under optimum conditions, as compared to traditional methods
Dynamic Load Prediction in Offshore Wind Turbines
No full textThe rapid development of the wind industry over the past few years has pushed turbine manufacturers to meet the growing energy demands by designing and producing large scale wind turbines.This also means development of larger monopile foundations for the foundation designers in the case of offshore wind turbines.\ Generally, the turbine tower and monopile are modeled together and the loads from the rotor-nacelle assembly are provided by turbine manufacturers.\ The offshore industry is now showing more interest in extracting the loads from the top mass by developing their own tools in order to reduce the dependency on the manufacturers. In order to aid in this process, the present master thesis aims to develop a linear model based on the concept of Dynamic Substructuring which employs a set of equations to compute the interface forces using the kinematics.\ Furthermore, the developed prediction model is used to analyze the loads occurring at the interface between the rotor-nacelle assembly and the tower for different wind speeds and wind conditions.Consequentially, the model was found to produce acceptable loads at higher wind speeds for selected degrees of freedom at the interface while failing to do the same for other degrees of freedom.The results in time domain were converted to the frequency domain to analyse the resonance.The influence of resonance on the interface degrees of freedom was found to be higher at wind speed below the rated condtion.\ These findings can be used as a basis to conduct further investigations into the application of numerical integration concepts to aeroelastic structures.Electrical Engineering | Sustainable Energy Technolog
Contribution to the grammar of the Kmhmouʔ language
No full textCette thèse est une contribution à la description du kmhmouʔ – langue à tradition orale parlée au Laos. Elle présente les caractéristiques générales de cette langue peu décrite dans la région de l’Asie du Sud-Est comme le montre notre référence bibliographique.Le kmhmouʔ, langue isolante, est dépourvue de marqueurs grammaticaux morphologiques. Les mots du kmhmouʔ sont pour la plupart pluricatégoriels et plurifonctionnels : la distinction verbo-nominale se fonde essentiellement sur des critères combinatoires. Les noms sont des noms massifs portant une signification notionnelle, et leur référentialité est conditionnée à la présence de déterminants nominaux (classificateurs, déictiques, quantifieurs et épithètes qualificatives) ; en l’absence de morphologie verbale, le temps, l’aspect et le mode peuvent être soit non-marqués et identifiables par le contexte, marqués par des moyens lexicaux de type adverbial ou circonstanciel, ou marqués par des particules d’origine catégorielle variée (majoritairement verbale), et le plus souvent empruntées aux langues de contact. La description grammaticale s’appuie sur des données spontanées recueillies lors d’un travail de terrain dans les villages kmhmouʔ et à la radio nationale lao pour l’émission en kmhmouʔ. Le travail de terrain a été conduit en kmhmouʔ, et l’analyse et l’interprétation du corpus ont bénéficié du fait que l’auteur est locuteur natif. Une partie du corpus recueilli (1h30 au total) est présenté en annexe, intégralement glosé et traduit en français et en lao. Cette thèse, outre qu’elle rend disponible pour la première fois les données et la grammaire du dialecte du kmhmouʔ de l’Est, ouvre des pistes de réflexion particulièrement intéressantes pour les travaux en typologie des langues isolantes et de la transcatégorialité, ainsi que la réflexion sur le rôle du contact de langue dans la grammaticalisation.This dissertation is a contribution to the description of Kmhmouʔ, a language with an oral tradition spoken in Laos. It presents the general characteristics of this language, which is among the less described languages of the region of Southeast Asia, as shown by the bibliography. Kmhmouʔ, an isolating language, does not exhibit any grammatical morphology. Words are mostly multi-categorial as regards parts of speech, and multi-functional: the verb-noun distinction is based essentially on combinatory properties of words. Nouns are basically all mass terms bearing a notional meaning, and they become countable and referential by means of determiners (classifiers, deictics, quantifiers and qualifiers); due to the lack of verb morphology, tense, aspect and mood can be either unmarked and identifiable by the context, marked by lexical means (adverbs or adverbial phrases), or marked by particles originating from various parts of speech (mostly verbs), and for the most part borrowed from contact languages.This grammatical description is based on spontaneous data collected during fieldwork in Kmhmouʔ villages and from the Lao national radio (Kmhmouʔ broadcast). The fieldwork was conducted in Kmhmouʔ, and the analysis and interpretation of the corpus benefited from the fact that the author is native speaker of Kmhmouʔ. A significant part of the corpus (1h30 in total) is provided in an appendix, fully glossed and translated into French and Lao.This thesis, besides making data and grammar of the Eastern Kmhmouʔ dialect available for the first time, opens up some new and challenging paths for the study of the typology of isolating languages and transcategoriality, as well as for studies of the role of language contact in grammaticalization
