Book Description
For a long time an automatic detection of contacts between humans was not possible. In this work a new generation of resource-aware RFID tags (proximity tags) is used which has the ability to detect reliable face-to-face contacts. This innovation opens up new research possibilities in the ?elds of human contact behaviour analysis, link prediction and indoor localisation. In this context the identi?cation of human contact structures and their underlying pro¬cesses is a prominent research topic. However, the analysis of of?ine social networks has been largely neglected. In this work face-to-face information is utilised to study the link prediction problem as well as dynamic and static contact patterns in face-to-face contact networks. Furthermore the in?uence of user interests and social contacts on the predictability of talk attendance is analysed. The localisation of humans in indoor environments is still a challenging problem. In literature, accurate positioning approaches exist. Unfortunately, these approaches requi¬re expensive hardware and an extensive deployment of suitable infrastructure. Therefo¬re novel approaches are presented that use proximity tags for positioning. All methods are evaluated using real-world data and it is shown that all approaches signi?cantly outperform state-of-the art indoor localisation approaches.

Book Description
By using various data inputs, ubiquitous computing systems detect their current usage context, automatically adapt their services to the user’s situational needs and interact with other services or resources in their environment on an ad-hoc basis. Designing such self-adaptive, context-aware knowledge processing systems is, in itself, a formidable challenge. This book presents core findings from the VENUS project at the Interdisciplinary Research Center for Information System Design (ITeG) at Kassel University, where researchers from different fields, such as computer science, information systems, human-computer interaction and law, together seek to find general principles and guidelines for the design of socially aware ubiquitous computing systems. To this end, system usability, user trust in the technology and adherence to privacy laws and regulations were treated as particularly important criteria in the context of socio-technical system design. During the project, a comprehensive blueprint for systematic, interdisciplinary software development was developed, covering the particular functional and non-functional design aspects of ubiquitous computing at the interface between technology and human beings. The organization of the book reflects the structure of the VENUS work program. After an introductory part I, part II provides the groundwork for VENUS by presenting foundational results from all four disciplines involved. Subsequently, part III focuses on methodological research funneling the development activities into a common framework. Part IV then covers the design of the demonstrators that were built in order to develop and evaluate the VENUS method. Finally, part V is dedicated to the evaluation phase to assess the user acceptance of the new approach and applications. The presented findings are especially important for researchers in computer science, information systems, and human-computer interaction, but also for everyone working on the acceptance of new technologies in society in general.

Book Description
Every second, users produce large amounts of image data from medical and satellite imaging systems. Image mining techniques that are capable of extracting useful information from image data are becoming increasingly useful, especially in medicine and the health sciences. Biomedical Image Analysis and Mining Techniques for Improved Health Outcomes addresses major techniques regarding image processing as a tool for disease identification and diagnosis, as well as treatment recommendation. Highlighting current research intended to advance the medical field, this publication is essential for use by researchers, advanced-level students, academicians, medical professionals, and technology developers. An essential addition to the reference material available in the field of medicine, this timely publication covers a range of applied research on data mining, image processing, computational simulation, data visualization, and image retrieval.

Book Description
This debate style textbook allows students to explore diverse, well-founded views on controversial African issues, pushing them to go beyond superficial interpretations and complicate and ground their understanding of the continent. From the positive images in the film Black Panther, to the derogatory remarks of former American President Donald Trump, the African continent often figures prominently in the collective, global imagination. This interdisciplinary collection covers 20 enduring and contemporary debates across a broad range of subjects affecting Africa, from development and health to agriculture, climate change, and urbanization. Each chapter has a pro and con view penned by a leading expert on the topic in an accessible and engaging style. These contrasting views on each issue are framed by an introduction that helps the student contextualize the debate and draw on further resources. Moreover, they enable readers to deepen their understanding of the topic, develop a more nuanced perspective, and foster classroom debates. This book is an excellent resource for Africa related courses across a range of disciplinary and interdisciplinary fields including African studies, anthropology, development studies, economics, environmental studies, geography, history, international studies, political science and public health.
