Design for energy-efficient and reliable fog-assisted healthcare IoT systems

Cardiovascular disease and diabetes are two of the most dangerous diseases as they are the leading causes of death in all ages. Unfortunately, they cannot be completely cured with the current knowledge and existing technologies. However, they can be effectively managed by applying methods of continuous health monitoring. Nonetheless, it is difficult to achieve a high quality of healthcare with the current health monitoring systems which often have several limitations such as non-mobility support, energy inefficiency, and an insufficiency of advanced services. Therefore, this thesis presents a Fog computing approach focusing on four main tracks, and proposes it as a solution to the existing limitations. In the first track, the main goal is to introduce Fog computing and Fog services into remote health monitoring systems in order to enhance the quality of healthcare. In the second track, a Fog approach providing mobility support in a real-time health monitoring IoT system is proposed. The handover mechanism run by Fog-assisted smart gateways helps to maintain the connection between sensor nodes and the gateways with a minimized latency. Results show that the handover latency of the proposed Fog approach is 10%-50% less than other state-of-the-art mobility support approaches. In the third track, the designs of four energy-efficient health monitoring IoT systems are discussed and developed. Each energy-efficient system and its sensor nodes are designed to serve a specific purpose such as glucose monitoring, ECG monitoring, or fall detection; with the exception of the fourth system which is an advanced and combined system for simultaneously monitoring many diseases such as diabetes and cardiovascular disease. Results show that these sensor nodes can continuously work, depending on the application, up to 70-155 hours when using a 1000 mAh lithium battery. The fourth track mentioned above, provides a Fog-assisted remote health monitoring IoT system for diabetic patients with cardiovascular disease. Via several proposed algorithms such as QT interval extraction, activity status categorization, and fall detection algorithms, the system can process data and detect abnormalities in real-time. Results show that the proposed system using Fog services is a promising approach for improving the treatment of diabetic patients with cardiovascular disease

MediaSync: Handbook on Multimedia Synchronization

This book provides an approachable overview of the most recent advances in the fascinating field of media synchronization (mediasync), gathering contributions from the most representative and influential experts. Understanding the challenges of this field in the current multi-sensory, multi-device, and multi-protocol world is not an easy task. The book revisits the foundations of mediasync, including theoretical frameworks and models, highlights ongoing research efforts, like hybrid broadband broadcast (HBB) delivery and users' perception modeling (i.e., Quality of Experience or QoE), and paves the way for the future (e.g., towards the deployment of multi-sensory and ultra-realistic experiences). Although many advances around mediasync have been devised and deployed, this area of research is getting renewed attention to overcome remaining challenges in the next-generation (heterogeneous and ubiquitous) media ecosystem. Given the significant advances in this research area, its current relevance and the multiple disciplines it involves, the availability of a reference book on mediasync becomes necessary. This book fills the gap in this context. In particular, it addresses key aspects and reviews the most relevant contributions within the mediasync research space, from different perspectives. Mediasync: Handbook on Multimedia Synchronization is the perfect companion for scholars and practitioners that want to acquire strong knowledge about this research area, and also approach the challenges behind ensuring the best mediated experiences, by providing the adequate synchronization between the media elements that constitute these experiences

Semantic discovery and reuse of business process patterns

Patterns currently play an important role in modern information systems (IS) development and their use has mainly been restricted to the design and implementation phases of the development lifecycle. Given the increasing significance of business modelling in IS development, patterns have the potential of providing a viable solution for promoting reusability of recurrent generalized models in the very early stages of development. As a statement of research-in-progress this paper focuses on business process patterns and proposes an initial methodological framework for the discovery and reuse of business process patterns within the IS development lifecycle. The framework borrows ideas from the domain engineering literature and proposes the use of semantics to drive both the discovery of patterns as well as their reuse

Designing personalized video-based crossmedia informal learning environments beyond iTV

Tese de doutoramento, Informática (Engenharia Informática), Universidade de Lisboa, Faculdade de Ciências, 2014Video is a very rich medium, in cognitive and affective terms, to convey information and support learning and entertainment like no other medium, and TV is a privileged way to watch it. However, by being traditionally watched in a more experiential and passive cognitive mode, TV and video are limited in their capacity to fully support learning so important in the lifelong learning era where learning is taking place in a wide variety of contexts and locations that calls for flexible environments. TV and video are limited in their capacity to fully support learning but may induce viewers to engage in more reflective modes, that can be supported to some extent by their adequate design, in interactive contexts and augmented by other media and devices, in diverse situations. The inclusion of iTV that has been gaining increasing attention from researchers, and practitioners, in the last few years, as part of rich and flexible crossmedia environments brings new opportunities in this respect. This situation justifies our research main goal to efficiently and flexibly support users learning informal opportunities created in video-based crossmedia environments, taking into account the different cognitive modes, contexts of use and taking advantage of the diverse devices being used in order to have each device contributing with what it does best. In order to illustrate, explore and validate our research, the eiTV application was conceptualized, prototyped and evaluated. It is capable to create videobased crossmedia informal learning environments, created as additional information to the video being watched, initially via iTV. These environments are accessed from iTV, PC and mobile devices (the most commonly used in crossmedia scenarios), depending on the preferred or most adequate device in each context of use.Fundação para a Ciência e a Tecnologia (FCT, SFRH/PROTEC/67727/2010, projeto UTA-Est/MAI/0010/2009

THE MATERIALITY AND SPATIALITY OF GRAVES AND GRAVE MARKERS IN THE BORDER REGION BETWEEN LUXEMBOURG AND GERMANY

This PhD thesis is the partial result of the research project entitled "Material Culture and Spaces of Remembrance – A Study of Cemeteries in Luxembourg in the Context of the Greater Region", under the coordination and supervision of Dr. Thomas Kolnberger and Associate Professor Sonja Kmec at the University of Luxembourg, and funded by the Fonds National de la Recherche (FNR). Building on prior, seminal research, this thesis aims to address the following questions concerning a specific, predefined region between Luxembourg and Germany, and selected cemeteries: • Does the research approach demonstrated from Anglo-American literature also apply to the sample in the border region between Luxembourg and Germany? • Does the analysis of materiality within its spatial context provide indications of a neighbouring effect, i.e. do material characteristics appear in spatial clusters? • With regards to the materiality that can be observed at the selected cemeteries, what might explain the specific appearance of, especially, graves and grave markers; i.e. what factors, such as cemetery regulations or stonemasons, might have had an influence? Based on a pilot project at Walferdange (Luxembourg) cemetery, as well as a specifically developed and designed data collection approach and tool, the author of this thesis collected the data from full populations of grave and grave marker material culture at three additional, selected cemeteries in Luxembourg and Germany, i.e. Wormeldange, Wincheringen and Konz, in order to allow an analysis of the present assemblage, reaching back into the late 19th century. The data gained thus were analysed using statistical and geo-spatial methods. The results of this data collection and analysis indicate the following: similar methods compared to, for example, work in the Anglo-American context, can generally be applied; since materiality of funeral culture shows a certain level of fluctuation and volatility over time in this specific research context, the researcher has to be careful in order to ensure appropriate dating; results in a chronologically limited data set in which also accurate spatiality cannot be ensured. Whileclusters of materiality can be identified visually, they do not in all instances produce stable results during statistical testing. Thus, a neighbouring effect cannot in all cases be supported and needs to be critically questioned in the face of different tactical confidence intervals. Moreover, potential cultural differences and differences in cemetery management, manifested for example in cemetery regulations, are not enough to explain the actual materiality and spatiality that can be found on the researched cemeteries. The author uses additional literature from business studies and economics in order to highlight a different approach in historical archaeological research in understanding grave monument genesis, their explanatory power and studying related phenomena in the future, hypothesizing about business related aspects in the interrelationship between stonemasons and their customers
