Quadriceps and hamstring muscle EMG activity during a football match
2012
Roudi Kalema (2012). Quadriceps and hamstring muscle EMG activity during a football match. Department of Biology of Physical, University of Jyvaskyla. Master’s Thesis in Exercise Physiology. 58 pages. Fatigue represents a reduction in the ability of muscle to generate force and in the context of football, it has been often related with injury. Surface electromyography is a valuable technique for evaluating muscle activation and fatigue but it has never been applied during a football match. The development of washable textile electrodes has opened up possibilities to investigate muscular activity in non-laboratory settings, without skin preparation and wires hanging around the body. It has a…
AI Ethics - Critical Reflections on Embedding Ethical Frameworks in AI Technology
2021
Embedding ethical frameworks in artificial intelligence (AI) technologies has been a popular topic for academic research for the past decade [1, 2, 3, 4, 5, 6, 7]. The approaches of the studies differ in how AI technology, ethics, role of technical artefacts and socio-technical aspects of AI are perceived. In addition, most studies define insufficiently what the connection between the process of embedding ethical frameworks to AI technology and the larger framework of AI ethics is. These deficiencies have caused that the concept of AI ethics and the construct of embedding ethical parameters into AI are used in an ambiguous, rather than in a complementary manner. One reason for the ambiguity…
A coupled discontinuous Galerkin-Finite Volume framework for solving gas dynamics over embedded geometries
2021
Author(s): Gulizzi, Vincenzo; Almgren, Ann S; Bell, John B | Abstract: We present a computational framework for solving the equations of inviscid gas dynamics using structured grids with embedded geometries. The novelty of the proposed approach is the use of high-order discontinuous Galerkin (dG) schemes and a shock-capturing Finite Volume (FV) scheme coupled via an $hp$ adaptive mesh refinement ($hp$-AMR) strategy that offers high-order accurate resolution of the embedded geometries. The $hp$-AMR strategy is based on a multi-level block-structured domain partition in which each level is represented by block-structured Cartesian grids and the embedded geometry is represented implicitly by a…
Miniature wireless photoplethysmography devices: integration in garments and test measurements
2012
Wireless PPG devices were developed and embedded in everyday clothes (bandage, scarf, cycling glove and wrist strap) to monitor cardiovascular state of free-moving persons. The corresponding software for measurements also has been developed and tested in laboratory. Real-time measurements of PPG signals were taken in parallel with a professional ECG reference device, and high correlation was demonstrated.
Mise en œuvre d’une architecture de gestion de collision pour le déploiement efficace d’un NoC sur multi-FPGA
2015
International audience; Le déploiement d’un NoC (Network On Chip) sur plusieurs FPGA nécessite que des routeurs partagent un même lien de communication entre FPGAs, créant des goulots d’étranglement [1]. Dans ce papier, nous proposons une structure de gestion de collision intégrée entre le NoC et le point d’accès du protocole FPGA. Cette structure est basée sur les algorithmes utilisés dans les réseaux informatiques et adaptée aux NoC [2].
Lääkintälaitteiden kyberturvallisuuden standardit ja testaaminen
2017
Tietotekniikkaa sisältävät lääkintälaitteet pitävät meidät hengissä, jos kehomme pettää. Esimerkiksi ostoskeskuksissa olevat älykkäät defibrillaattorit antavat maallikoillekin mahdollisuuden antaa tehokasta ensiapua sydänkohtaukseen. Tietotekniikan käyttäminen lääkintälaitteissa tuo mahdollisuuksien lisäksi uhkia. Tässä tutkielmassa perehdytään siihen, miten standardit ja testaaminen edistävät kyberturvallisuutta, uhkien torjumista. Ensin tehdään katsaus kirjallisuuteen ja standardeihin ja sitten kytketään tieto käytäntöön testaamalla potilasmonitoria kirjallisuuden pohjalta. Tulos oli, että tutkittava potilasmonitori oli hyvin avoin fyysisen käyttöliittymän kautta. Esimerkiksi potilastiedo…
Measurement and communication interfaces for distributed generation in smart grids
2013
The aim of this work is to perform a feasibility study on the measurement and communication strategies for the development of a new generation of interface devices for distributed generators and their integration on smart grids. The communication system can use one or more technologies, at the various levels, creating a low cost network infrastructure, in the framework of a SCADA (Supervisory Control and Data Acquisition) architecture. As regards the measurements, the attention is focused on the anti-islanding protection, based on a hybrid solution, which makes use of local measurements and communications with the grid, at both MV and LV level by employing the PLC technology. Some simulatio…
Institutional perspectives in transition : research groups’ profiles and embeddedness in organisational and national context
2019
Research into differentiation and profiling of knowledge producing institutions through the lenses of institutional logics and field embeddedness have proliferated in recent years. By discussing this process in the context of research groups, as those basic units in which knowledge production epistemically and practically takes place, this article offers a contribution to the theoretical discussion on organisational differentiation. Based on a small-N comparative case study of research groups operating in different national and organisational contexts on a single, highly competitive and interdisciplinary applied sciences field, nanosciences, the article proposes research group profiles as h…
Video Scene analysis for a configurable hardware accelerator dedicated to Smart Camera
2012
International audience; According to the Center for Research and Prevention of Injuries report, fall-caused injuries of elderly people in UE- 27 are five times as frequent as other injury causes which reduce considerably their mobility and independence. Among the diverse applications of computer vision systems, object detection and event recognition are of the most prominent related recognition and motion analysis, that is, researchers had the idea to spread it in fall detection. The fall event, extracted automatically from the video scene represents itself, crucial information that can be used to alert emergency. In this context, visual information on the corresponding scene is highly impo…
FPGA-based smart camera : industrial applications
2013
International audience; For the last two decades and still today, smart cameras offer innovative solutions for industrial vision applications. This kind of system associates a flexible image acquisition with high-speed processing possibilities. Many smart camera designs are based on FPGA components to obtain these two features. Indeed, the FPGA enables the CMOS sensor to be controlled and therefore to propose a configurable acquisition according to the application constraints (i.e. dynamic windowing). The configurable structure of a FPGA represents a key advantage for modifying the embedded processing (even on-the-fly using dynamic reconfiguration). Meanwhile, FPGA components offer a large …
