Available in PDF, EPUB and Kindle. Book excerpt: model. In general, the mean atomic positions and the geometrical parameters calculated from them are more accurate if the more sophisticated anisotropic model has been used for the thermal motion during structure refinement. Low temperature data collection also results in more accurately determined structures. By decreasing the temperature at which data is collected, the intensities and number of data observed is increased. Since hydrogen atoms have only a single electron, they scatter X-rays very weakly, and they can be observed experimentally only if the data are of good quality. Finally, in the absence of systematic errors in data collection or refinement, tae greater the number of observed data relative to the number of independent atoms, the better the atomic resolution will be. Table 1 is a summary of the information used in assessing the reliability of a structure. Neutron diffraction is the result of interaction of atomic nuclei with a neutron beam. The intensi ty of the diffracted beam is not proportional to atomic number. Hydrogen, deuterium, carbon, oxygen and nitrogen scatter neutrons with almost equal intensity. In addition, hydrogen and deuterium scatter out of phase so that they can be distinguished wita high precision. 20-Methyl-5-pregnene-3S,20-diol (PR104N) is the only steroid which has been the subject of a neutron diffraction study. The study was undertaken to examine the stereospecificity of Grignard addition using deuterated reagent. Data were collected at 123°K.

Book excerpt: Industries that use machines in their day-to-day operations include power, automobile, steel, and chemical plants sectors, to mention just a few. As these industries' services evolve, their machines must also evolve. To design these machines, you must understand both their performance requirements and the physical concepts governing their motion. Emphasizing the industrial relevance of the subject matter, Mechanics of Machines provides the fundamental information students need to decide on the criteria for designing new machines and for analyzing the root cause of problems arising out of malfunctioning of existing equipment.

Download or read book Intelligent and Fuzzy Techniques for Emerging Conditions and Digital Transformation written by Cengiz Kahraman and published by Springer Nature. This book was released on 2021-08-23 with total page 954 pages. Available in PDF, EPUB and Kindle. Book excerpt: This book presents recent research in intelligent and fuzzy techniques. Emerging conditions such as pandemic, wars, natural disasters and various high technologies force people for significant changes in business and social life. The adoption of digital technologies to transform services or businesses, through replacing non-digital or manual processes with digital processes or replacing older digital technology with newer digital technologies through intelligent systems is the main scope of this book. It focuses on revealing the reflection of digital transformation in our business and social life under emerging conditions through intelligent and fuzzy systems. The latest intelligent and fuzzy methods and techniques on digital transformation are introduced by theory and applications. The intended readers are intelligent and fuzzy systems researchers, lecturers, M.Sc. and Ph.D. students studying digital transformation. Usage of ordinary fuzzy sets and their extensions, heuristics and metaheuristics from optimization to machine learning, from quality management to risk management makes the book an excellent source for researchers.

Download or read book John Stewart of Baldynneis Roland Furious written by Donna Heddle and published by BRILL. This book was released on 2007-11-30 with total page 365 pages. Available in PDF, EPUB and Kindle. Book excerpt: The poetry of John Stewart of Baldynneis, one of James VI's soi disant Castalian Band, is a relatively unknown phenomenon of the Renaissance period. This book is a critical edition of his epic poem Roland Furious, supposedly a translation of Ludovico Ariosto’s Orlando Furioso into Scots but actually a brilliantly original poem which directly follows guidelines given by James VI for the creation of such literature in the Scottish vernacular. A fully annotated version of the text is given, along with a critical induction discussing the main European influences on Stewart's work, notes to the text, an appendix of proper and personal names, and a full glossary. This book provides an important link in the history of Scottish poetry. Brill's Texts and Sources in Intellectual History, vol. 4
