Multi-objective optimization for computation offloading in mobile-edge computing
2017
Mobile-edge cloud computing is a new cloud platform to provide pervasive and agile computation augmenting services for mobile devices (MDs) at anytime and anywhere by endowing ubiquitous radio access networks with computing capabilities. Although offloading computations to the cloud can reduce energy consumption at the MDs, it may also incur a larger execution delay. Usually the MDs have to pay cloud resource they used. In this paper, we utilize queuing theory to bring a thorough study on the energy consumption, execution delay and price cost of offloading process in a mobile-edge cloud system. Specifically, both wireless transmission and computing capabilities are explicitly and jointly co…
Apuvälineet ja teknologia osana fysioterapian ja fysioterapeutin ydinosaamista
2017
Aiempi tutkimustieto osoittaa, että fysioterapiaa ja apuvälineitä, terveys- ja hyvinvointiteknologiaa tai etäteknologiaa yhdistävää tutkimustietoa on vähän. Tarvitaan lisää tietoa apuvälineiden, teknologian ja etäteknologian käytöstä fysioterapiassa, niiden yhteydestä fysioterapian ydinosaamiseen sekä siitä, mitkä tekijät vaikuttavat niiden käyttöön fysioterapiassa. Tämän pro gradu -tutkielman tarkoituksena oli selvittää, miten suomalaisten fysioterapeuttien yksilölliset ja työhön liittyvät taustatekijät vaikuttavat apuvälineiden, terveys- ja hyvinvointiteknologian sekä etäteknologian käyttöön fysioterapian ydinosaamisalueilla. Lisäksi työn tarkoituksena oli selvittää, miten suomalaiset fys…
Imperial straightening devices in disciplinary choices of academic knowledge production
2021
Abstract In this piece, the authors question whether critical language research, in its complex collection of researcher choices, is possible beyond the discursive imaginary of critical academic scholarship. In other words, how do (allegedly) anticolonial efforts re-orient towards contribution to the imperial record? We present three vignettes, through which we grapple with the notion that researcher choice exists within the solipsism of academia. In doing so, we frame research and scholarship as a collection of choices, which we believe are better understood as a collection of fraught dilemmas. These dilemmas recognize that all academic scholarship production and its processes are birthed …
Use of the directional atherectomy for the treatment of femoro-popliteal lesions in patients with critical lower limb ischemia
2016
Femoro-popliteal PTA for the treatment of critical limb ischemia is frequently associated with unsatisfactory procedural success rates while directional atherectomy (DCA) has improved success rate since claudicant patients undergoing percutaneous treatment of femoro-popliteal obstructive disease. The aim of this prospective study is to evaluate the safety, efficacy and procedural success of DCA, at one year, in the percutaneous treatment of femoro-popliteal obstructive disease in patients with critical limb ischemia.Methods. From March 2012 to March 2013 18 consecutive patients with critical limb ischemia were treated with DCA (Turbohawk/ Covidien-ev3 Endovascular Inc., North Plymouth, Minn…
UAV-Assisted Data Collection in Wireless Sensor Networks: A Comprehensive Survey
2021
Wireless sensor networks (WSNs) are usually deployed to different areas of interest to sense phenomena, process sensed data, and take actions accordingly. The networks are integrated with many advanced technologies to be able to fulfill their tasks that is becoming more and more complicated. These networks tend to connect to multimedia networks and to process huge data over long distances. Due to the limited resources of static sensor nodes, WSNs need to cooperate with mobile robots such as unmanned ground vehicles (UGVs), or unmanned aerial vehicles (UAVs) in their developments. The mobile devices show their maneuverability, computational and energy-storage abilities to support WSNs in mul…
Does time spent on device security and privacy inhibit online expression?
2019
Freedom of expression is a recognized human right. More recently, the UN has resolved that unrestricted access to the Internet is also a human right. A commonly accepted benefit of the Internet is that it serves as a platform for free expression. Usage of the Internet for free expression can be a way of circumventing censorship or other hindrances that prevent citizens' freedom of expression in more traditional publishing media. However, the Internet has unique security and privacy risks that may affect users' attitudes toward expressing themselves online. In the online environment, users with controversial viewpoints may be reluctant to express the viewpoints due to concern about possible …
Time-Frequency Characteristics of In-Home Radio Channels Influenced by Activities of the Home Occupant
2019
While aging is a serious global concern, in-home healthcare monitoring solutions are limited to context-aware systems and wearable sensors, which may easily be forgotten or ignored for privacy and comfort reasons. An emerging non-wearable fall detection approach is based on processing radio waves reflected off the body, who has no active interaction with the system. This paper reports on an indoor radio channel measurement campaign at 5.9 GHz, which has been conducted to study the impact of fall incidents and some daily life activities on the temporal and spectral properties of the indoor channel under both line-of-sight (LOS) and obstructed-LOS (OLOS) propagation conditions. The time-frequ…
The explanatory variables of narrative transportation and consumer engagement with a transmedia consumption experience
2019
International audience; Professionals in the cultural sector are increasingly designing transmedia narrative devices. By that new strategy, they expect to increase cultural consumption and attendance. Considering the central role of the narrative transportation during the transmedia experience, this article presents results about six anticipated antecedents of this process experienced by users of a transmedia device that combines digital and physical elements, and deals with the heritage history of a French province. The six variables tested are gender, age, level of education (to describe the socio-demographic profile), geographical proximity (to proxy the familiarity with the topic and co…
Beyond good and evil: The impact of digital environment in family life
2019
Internet has changed the way we interact with others and has become an essential tool for daily activities. Children and adolescents are the main users of new digital technologies and their first contact with a screen happens increasingly earlier in life. Its premature use can be dangerous: technology represents a “supernormal stimulus” that can act on the brain reward circuit and affect neural development. In this article we describe the effects of technology on the brain, well-being, social and family relationships, highlighting both positive and negative ones: rather than defining a priori any type of technology as “good” or “bad”, we should consider how specific applications are used in…
An overview of a novel LC resonant device able to improve Power Quality in active and passive distribution networks
2004
Nowadays power distribution systems are under a rapid evolution. The widespread penetration of distributed generation is bringing about new operating conflicts, which are adding to traditional power quality issues. The paper aims to analyse the performance of a new LC device able to improve power quality in electrical distribution systems, even in presence of distributed generation units. The different possible applications of the device are shown and the performances are proved by means of computer simulation. The first experimental results are also presented.
