Image and video encryption : From digital rights management to secured personal communication
Image and Video Encryption provides a unified overview of techniques for encryption of images and video data. This ranges from commercial applications like DVD or DVB to more research oriented topics and recently published material. This volume introduces different techniques from unified viewpoint, then evaluates these techniques with respect to their respective properties (e.g., security, speed.....). Encryption of visual data is an important topic in the area of mutimedia security, applications range from digital rights management (DVD, DVB) ) to secure personal communications. Within this topic area, we face several aims which contradict each other. What we thrive on is good compression, fast compression, high security, fast encryption, bitstream compliance, little power consumption and little memory requirements. The authors experimentally compare different approaches proposed in the literature and include an extensive bibliography of corresponding published material. Image and Video Encryption is designed for a professional audience composed of researchers and practitioners in industry. The book is also suitable for graduate-level students in computer science and electrical engineering.

How does the Galaxy Work? : A Galactic Tertulia with Don Cox and Ron Reynolds
Presents a multi-disciplinary approach to the physical mechanisms which structure the shape, evolution and fate of the Galaxy. It contains 4 panel sessions (the recording transcripts of the galactic 'tertulias'), an introductory historical overview on the Galaxy research, 17 reviews, and the proceedings of more than 50 oral and poster contributions. This book is not a new edition of a previous volume but it is in some way related to the book "The Formation of the Milky Way" (1995; Cambridge University Press), which contains the proceedings of the first IAA-IAC-University of Pisa meeting, held in Granada ten years ago, on the formation of the Milky Way, (see Shore's introduction). Where many other books focus their attention on singular galactic components or specific driving forces, this title provides a wide overview on the gaseous and stellar components and on the physical mechanisms which maintain the dynamical equilibrium of such a complex system as the Galaxy. The book, intended for graduate students and researchers, provides a valuable overview on the different physical mechanisms which drive the galactic gas-stars feedback.
Housing Market Dynamics in Africa
Utilizes new data to thoroughly analyze the main factors currently shaping the African housing market. Some of these factors include the supply and demand for housing finance, land tenure security issues, construction cost conundrum, infrastructure provision, and low-cost housing alternatives. Through detailed analysis, the authors investigate the political economy surrounding the continent’s housing market and the constraints that behind-the-scenes policy makers need to address in their attempts to provide affordable housing for the majority in need. With Africa’s urban population growing rapidly, this study highlights how broad demographic shifts and rapid urbanization are placing enormous pressure on the limited infrastructure in many cities and stretching the economic and social fabric of municipalities to their breaking point. But beyond providing a snapshot of the present conditions of the African housing market, the book offers recommendations and actionable measures for policy makers and other stakeholders on how best to provide affordable housing and alleviate Africa’s housing deficit.
Housing Estates in Europe : Poverty, Ethnic Segregation and Policy Challenges
Explores the formation and socio-spatial trajectories of large housing estates in Europe. Are these estates clustered or scattered? Which social groups originally had access to residential space in housing estates? What is the size, scale and geography of housing estates, their architectural and built environment composition, services and neighbourhood amenities, and metropolitan connectivity? How do housing estates contribute to the urban mosaic of neighborhoods by ethnic and socio-economic status? What types of policies and planning initiatives have been implemented in order to prevent the social downgrading of housing estates?The collection of chapters in this book addresses these questions from a new perspective previously unexplored in scholarly literature. The social aspects of housing estates are thoroughly investigated (including socio-demographic and economic characteristics of current and past inhabitants; ethnicity and segregation patterns; population dynamics; etc.), and the physical composition of housing estates is described in significant detail (including building materials; building form; architectural and landscape design; built environment characteristics; etc.).

The new parallel class A&B power amplifier can not only increase the transmitter's output power in the linear range, but can also result in significant savings in power consumption. High-Linearity CMOS RF Front-End Circuits can be used as a textbook for graduate courses in RF CMOS design and will also be useful as a reference for the practicing engineer.
High-Latitude Bioerosion : The Kosterfjord Experiment
Bioerosion is the major force driving the degradation of marine skeletal carbonates and limestone coasts. A wide spectrum of mechanical and/or chemical boring, scraping or crushing organisms break down calcereous substrates, comprising various grazers, macroborers and especially microborers. Their traces on and within hard substrates are known from fossil carbonates as old as the Precambrian and serve as valuable palaeoenvironmental indicators. Bioerosion processes have been extensively studied in tropical seas, while corrsponding investigations from cold-temperate to polar settings remain sparse. For the first time, an experimental study yields insight into the pace of carbonate degradation and the chronology of boring community development along a bathymetric gradient in a high-latitude setting.
High-Grade Gliomas : Diagnosis and Treatment
This is truly an exciting time in the field of neuro-oncology, particularly in the area of hi- grade gliomas. The management of patients with high-grade gliomas has historically been one of the most challenging and disheartening fields in medicine, where failure is the rule and longevity is the exception. The jaded often state that despite purported advances in surgical and radiotherapeutic techniques and a myriad of clinical trials of medical therapies, the s- vival statistics for glioblastoma have not changed in the last three decades. The nihilism associated with these tumors is such that some practitioners still advise against treatment or even biopsy, recommending palliative care with the diagnosis based only on history and an MRI scan. If the current state-of-the-art in the diagnosis and management of high-grade gliomas was truly so bleak, there would be no reason to compile and publish a monograph on the subject. The fact is that we have recently entered an era where real progress is being made in our understanding and treatment of high-grade gliomas that is directly benefiting some patients. We are slowly but surely chipping away at this problem. One approach has exploited correlations between particular molecular markers and therapeutic response.
Higher Education and Graduate Employment in Europe : Results from Graduates Surveys from Twelve Countries
The book indicates a noteworthy variety among economically advanced countries in the competences fostered by Higher Education and the emphasis placed either on laying a broad basis of knowledge or direct preparation for professional tasks. While universities in some countries are strongly involved in ensuring a rapid transition from study to employment, in other countries a long period after graduation is widespread for the search of a suitable career. Graduates from some countries appreciate their study experiences though they criticize a weak preparation for their subsequent assignments, while others less satisfied with higher education in their retrospective view note a satisfying preparation for the world of work. Study often turns out useful to lead to challenging tasks even though remuneration and status remain below expectations.
Higher education : Handbook of theory and research ; Vol. 19
In this Book provide some reflections on own contributions to the field of higher education. Describing how andwhy I conducted some of my studies may, I hope, help students understandthe process of doing research. Early in my graduate studies I came across abook about how sociologists work. The book was written by sociologistswho described in some detail how they went about doing particularresearch studies. This essay follows that same approach in describing myown rationale and experiences in carrying out studies in higher education,Bill McKeachie provided a rich foundation in theevaluation and improvement of teaching that helped me identify worth-while research directions. My own goal has always been to be pragmaticand to hope my findings would make a difference — in other words I havehoped that my research results would somehow be of service to someonein our colleges and universities.
