This up-to-date text deals with the mutual interaction and energy transfer between electronic defect states of F centres and defect ions and neighbouring molecular defects in alkali halides. It includes more than 100 illustrations and figures, plus many previously unpublished results.
This seven-year retrospective covers the significant results, reported in these fields during that time, and includes abstracts of papers which appeared after the publication of Defect and Diffusion Forum, Volumes 150-151 and Volumes 181-182, (which were last to cover these topics systematically) and the end of August 2004 (allowing for vagaries of journal availability).
Invasion of privacy and misuse of personal data are among the most obvious negative effects of today's information and communication technologies. Besides technical issues from a variety of fields, privacy legislation, depending on national activities and often lacking behind technical progress, plays an important role in designing, implementing, and using privacy-enhancing systems. Taking into account technical aspects from IT security, this book presents in detail a formal task-based privacy model which can be used to technically enforce legal privacy requirements. Furthermore, the author specifies how the privacy model policy has been implemented together with other security policies in accordance with the Generalized Framework for Access Control (GFAC). This book will appeal equally to R&D professionals and practitioners active in IT security and privacy, advanced students, and IT managers.
Plastic deformation (PD) changes drastically the content of imperfections in solids: the concentration of dislocation, point defects, clusters and of dispersed impurities increases up to some orders of magnitude. In alkali halides these changes affect appreciably most physical properties of the sample. This research dealt mainly with the influence of PD on the thermoluminescence (TL) of alkali halide single crystals; the work was expanded to include the study of TL in undeformed crystals, in order to clarify the nature of the various traps. The influence of plastic deformation on dipolar complexes (Sr++ (+)) in doped samples was studied by means of ionic thermoconductivity (ITC), a method recently conceived. Some work was done also on the absorption edge and on the manganese ESR in deformed samples.
This extensive survey covers defects in nonmetals, emphasizing point defects and point-defect processes. It encompasses electronic, vibrational, and optical properties of defective solids, plus dislocations and grain boundaries. 1985 edition.
