Panich, "Physical Properties of the Low-Dimensional A3B6 and A3B3C62 Compounds " English | ISBN: 1608761207 | 2010 | 287 pages | PDF | 8 MB The authors present the first monograph on electronic properties, lattice dynamics and phase transitions in TlX and TlMX2 (M = Ga, In; X = Se, S, Te) compounds. These chalcogenides belong to a family of the low-dimensional ?3?6 and A3B3C62 semiconductors possessing chain or layered structure. They are of significant interest because of highly anisotropic properties, semiconductor and photoconductor behaviour, non-linear effects in their current-voltage characteristics (including a region of negative differential resistance), switching and memory effects, second harmonic optical generation, ferroelectricity, relaxor behaviour and potential applications in optoelectronic devices. We review (i) crystal structure of the compounds, (ii) their transport properties under ambient conditions, (iii) experimental studies of the electronic structure, (iv) band structure calculations, (v) transport properties, semiconductor-metal phase transitions and band structure under high pressure, (vi) ferroelectric/structural phase transitions at ambient pressure, soft modes and incommensurate states, (vii) electronic nature of the ferroelectric phase transitions, (viii) lattice dynamics in ?3?6 and A3B3C62 crystals and their solid solutions, (ix) elastic properties and (x) recently discovered relaxor behaviour, nanodomains and quantum dots in doped and irradiated crystals. Physical properties of some related low-dimensional compounds are also discussed. New perspectives in studying and application of the aforementioned semiconductors are considered. The monograph is addressed to physicists, materials scientists, engineers and students who are interested in physics of the low-dimensional compounds, lattice dynamics, phase transitions and ferroelectricity.  Free Download Shao-Ping Li, "Pharmacological Activity-Based Quality Control of Chinese Herbs" English | ISBN: 1604568232 | 2013 | 468 pages | PDF | 11 MB Natural products are the most successful source of drugs. Of the 877 small-molecule new chemical entities introduced between 1981 and 2002, roughly half were natural products, semi-synthetic natural product analogues or natural mimics. Chinese herbs (traditional Chinese medicines, TCMs) have been used for prevention and treatment of diseases for thousands years. It has been attracting intensive attention in the trends of back to nature. As herbal medicines, the conditions of growth, harvest time, process and storage etc. will undoubtedly affect the presence and concentration of the bioactive constituents, thus affecting their quality and efficacy. Up to date, there are few books focussing on the relationship, which is the bridge between TCM and modern medical science, of traditional clinic uses, pharmacological activities and quality control of Chinese herbs.Unfortunately, bioactive compounds in Chinese herbs are usually not or only partially known. Actually, the active compounds considered in Chinese herbs may be different according to their clinical indication. In addition, it is considered that the curative effect of Chinese herbs is an integrative result of a number of bioactive compounds. Therefore, how to control the quality is a big problem. We would like to discuss the quality control based on their traditional clinical uses and pharmacological activities in this book, which is the fundamental step towards developing and modernising such products into evidence based medicines. It will also help the peoples to understand TCMs in modern scientific angles. This book is designed primarily as a textbook for or adjunct to course in herbal remedies, food safety or quality control of herbs. It is also a professional reference whom is in the area of drug discovery, pharmaceutical analysis and food chemistry.  Free Download Penser L'espace En Mesopotamie: Contributions a La Comprehension Spatiale a Travers Les Amenagements: Scripta Memoriae Jean-claude Margueron Dedicata (French Edition) by Laura Battini French | May 2, 2024 | ISBN: 1803277572 | 226 pages | PDF | 23 Mb Les recherches sur les amenagements n'ont pas ete au centre de l'attention des archeologues. Parfois, elles sont conduites sans la rigueur necessaire et manquent de definitions claires, l'identification des amenagements restant largement subjective, inexpliquee et dependante de l'interpretation des espaces que les amenagements auraient du aider a identifier. La serie des workshops dont est issu ce livre s'est penchee sur des questions essentielles, telles que la perception des espaces, leur fonctionnalite eu egard aux amenagements, la multifonctionnalite, la question de l'etage. Les reponses a ces questions peuvent etre encore partielles, mais a present la necessite d'analyses plus rigoureuses et moins guidees par des aprioris s'impose, me semble-t-il. De meme, l'analyse archeologique a tout interet a discuter avec les textes qui, pour ces questions d'architecture, s'averent tout a la fois episodiques, riches et complexes. Le livre est dedie a Jean-Claude Margueron, qui n'a cesse d'encourager les archeologues a travailler rigoureusement sur l'architecture. Il se compose de deux parties, precedees par une biographie de Jean Margueron par Beatrice Muller et la liste presque definitive des ses ecrits. La premiere partie (Force, defaillances et problematiques des amenagements) comprend trois chapitres generaux, qui posent les problematiques, tentent de definir ce qu'on entend par amenagement, montrent la methode et soulignent les difficultes de la recherche. La deuxieme partie (Etude de cas) comprend sept chapitres, qui partent de l'etude de cas precis pour essayer de montrer l'importance de l'etude des amenagements et l'utilite d'une confrontation avec les donnees textuelles.

Free Download Optimization of PID Controllers Using Ant Colony and Genetic Algorithms By Muhammet Ünal, Ayça Ak, Vedat Topuz, Hasan Erdal (auth.) 2013 | 88 Pages | ISBN: 3642328997 | PDF | 4 MB Artificial neural networks, genetic algorithms and the ant colony optimization algorithm have become a highly effective tool for solving hard optimization problems. As their popularity has increased, applications of these algorithms have grown in more than equal measure. While many of the books available on these subjects only provide a cursory discussion of theory, the present book gives special emphasis to the theoretical background that is behind these algorithms and their applications. Moreover, this book introduces a novel real time control algorithm, that uses genetic algorithm and ant colony optimization algorithms for optimizing PID controller parameters. In general, the present book represents a solid survey on artificial neural networks, genetic algorithms and the ant colony optimization algorithm and introduces novel practical elements related to the application of these methods to process system control.
