Sensor-Based Locomotion Data Mining for Supporting the Diagnosis of Neurodegenerative Disorders: A Survey
Locomotion characteristics and movement patterns are reliable indicators of neurodegenerative diseases (NDDs). This survey provides a systematic literature review of locomotion data mining systems for supporting NDD diagnosis. We discuss techniques for discovering low-level locomotion indicators, sensor data acquisition and processing methods, and NDD detection algorithms. The survey presents a comprehensive discussion on the main challenges for this active area, including the addressed diseases, locomotion data types, duration of monitoring, employed algorithms, and experimental validation strategies. We also identify prominent open challenges and research directions regarding ethics and privacy issues, technological and usability aspects, and availability of public benchmarks
Locomotion Traces Data Mining for Supporting Frail People with Cognitive Impairment
The rapid increase in the senior population is posing serious challenges to national healthcare systems. Hence, innovative tools are needed to early detect health issues, including cognitive decline. Several clinical studies show that it is possible to identify cognitive impairment based on the locomotion patterns of older people. Thus, this thesis at first focused on providing a systematic literature review of locomotion data mining systems for supporting Neuro-Degenerative Diseases (NDD) diagnosis, identifying locomotion anomaly indicators and movement patterns for discovering low-level locomotion indicators, sensor data acquisition, and processing methods, as well as NDD detection algorithms considering their pros and cons. Then, we investigated the use of sensor data and Deep Learning (DL) to recognize abnormal movement patterns in instrumented smart-homes. In order to get rid of the noise introduced by indoor constraints and activity execution, we introduced novel visual feature extraction methods for locomotion data.
Our solutions rely on locomotion traces segmentation, image-based extraction of salient features from locomotion segments, and vision-based DL. Furthermore, we proposed a data augmentation strategy to increase the volume of collected data and generalize the solution to different smart-homes with different layouts. We carried out extensive experiments with a large real-world dataset acquired in a smart-home test-bed from older
people, including people with cognitive diseases. Experimental comparisons show that our system outperforms state-of-the-art methods
On a wildlife tracking and telemetry system : a wireless network approach
Includes abstract.Includes bibliographical references (p. 239-261).Motivated by the diversity of animals, a hybrid wildlife tracking system, EcoLocate, is proposed, with lightweight VHF-like tags and high performance GPS enabled tags, bound by a common wireless network design. Tags transfer information amongst one another in a multi-hop store-and-forward fashion, and can also monitor the presence of one another, enabling social behaviour studies to be conducted. Information can be gathered from any sensor variable of interest (such as temperature, water level, activity and so on) and forwarded through the network, thus leading to more effective game reserve monitoring. Six classes of tracking tags are presented, varying in weight and functionality, but derived from a common set of code, which facilitates modular tag design and deployment. The link between the tags means that tags can dynamically choose their class based on their remaining energy, prolonging lifetime in the network at the cost of a reduction in function. Lightweight, low functionality tags (that can be placed on small animals) use the capabilities of heavier, high functionality devices (placed on larger animals) to transfer their information. EcoLocate is a modular approach to animal tracking and sensing and it is shown how the same common technology can be used for diverse studies, from simple VHF-like activity research to full social and behavioural research using wireless networks to relay data to the end user. The network is not restricted to only tracking animals â environmental variables, people and vehicles can all be monitored, allowing for rich wildlife tracking studies

Enhanced Living Environments
This open access book was prepared as a Final Publication of the COST Action IC1303 âAlgorithms, Architectures and Platforms for Enhanced Living Environments (AAPELE)â. The concept of Enhanced Living Environments (ELE) refers to the area of Ambient Assisted Living (AAL) that is more related with Information and Communication Technologies (ICT). Effective ELE solutions require appropriate ICT algorithms, architectures, platforms, and systems, having in view the advance of science and technology in this area and the development of new and innovative solutions that can provide improvements in the quality of life for people in their homes and can reduce the financial burden on the budgets of the healthcare providers. The aim of this book is to become a state-of-the-art reference, discussing progress made, as well as prompting future directions on theories, practices, standards, and strategies related to the ELE area. The book contains 12 chapters and can serve as a valuable reference for undergraduate students, post-graduate students, educators, faculty members, researchers, engineers, medical doctors, healthcare organizations, insurance companies, and research strategists working in this area
Telemedicine
Telemedicine is a rapidly evolving field as new technologies are implemented for example for the development of wireless sensors, quality data transmission. Using the Internet applications such as counseling, clinical consultation support and home care monitoring and management are more and more realized, which improves access to high level medical care in underserved areas. The 23 chapters of this book present manifold examples of telemedicine treating both theoretical and practical foundations and application scenarios

High-throughput screening technologies for identification and expression of functional domains of proteins of biomedical importance
The ability to produce multi-milligram quantities of a recombinant âtargetâ protein in a proteolytically stable, soluble, and functional form is often necessary for subsequent biochemical, biophysical and structure-based analyses. Sub-constructs expressing only part of a large target protein can often be useful. Combinatorial Domain Hunting (CDH) is a methodology that allows the rapid production of sub- constructs via a random DNA fragmentation technique. One particular issue with CDH is that it can be used to identify globular regions or domains of a target protein, but does not take account of the functional properties of such domains; therefore some âhitsâ are not useful, because they exclude these functional regions. Here, we have attempted to enhance the CDH methodology by including an additional screening step that could specifically identify those constructs expressing functional protein domains. However, whilst rigorous testing of this functionality screen proved it to be successful under selective conditions, it was not considered suitable for inclusion in the CDH method.
CDH was also used to identify highly expressed, proteolytically stable regions of a previously largely uncharacterized protein, and to investigate their functionality. Human Claspin is a large, highly charged, S=phase specific âmolecular scaffoldâ protein, with no identifiable sub-domains or enzymatic function(s). However, Claspin is known to make multiple different protein-protein interactions at replication forks during the intertwined processes of DNA replication and DNA replication-coupled repair. CDH successfully identified a number of N-terminal expression constructs that could be expressed and purified to a high degree of homogeneity. Structural and functional analyses of these protein fragments indicated that the N-terminus of human Claspin is intrinsically disordered, and elongated in nature. However, these regions may become ordered upon binding to their respective protein or macromolecular partner(s). Furthermore, several N-terminal fragments were found to be able to bind to both single- or double-stranded DNA when longer than 16 nucleotides/base-pairs in length. Additionally, the phospho-specific protein-protein interaction made by human Claspin, with the checkpoint kinase Chk1 was further investigated
