Energy-Efficient Resource Allocation and User Scheduling for Collaborative Mobile Clouds With Hybrid Receivers
2016
In this paper, we study the resource allocation and user scheduling algorithm for minimizing the energy cost of data transmission in the context of OFDMA collaborative mobile cloud (CMC) with simultaneous wireless information and power transfer (SWIPT) receivers. The CMC, which consists of several collaborating MTs offers one potential solution for downlink con- tent distribution and for the energy consumption reduction at the terminal side. Meanwhile, as RF signal can carry both informa- tion and energy simultaneously, the induced SWIPT has gained much attention for energy efficiency design of mobile nodes. Previous work on the design of CMC system mainly focused on the cloud formulation o…
A Web Application for the Remote Control of Multiple Unmanned Aerial Vehicles
2019
Unmanned Aerial Vehicles (UAVs) are receiving an increasing attention from the research and industry community, and today they are adopted for several civilian and military applications. However, state of the art technologies are still based on a single UAV either directly controlled by the human operator or supervised through the manual definition of a flight plan. As a result, scalability is still a significant limitation for such systems, especially when large areas need to be monitored. In this paper we propose a web based application for the control of multiple UAVs. The application has three layers. The first layer allows the user to remotely submit a monitoring mission through a web …
Interactive multiobjective optimization system WWW-NIMBUS on the Internet
2000
Abstract NIMBUS is a multiobjective optimization method capable of solving nondifferentiable and nonconvex problems. We describe the NIMBUS algorithm and its implementation WWW-NIMBUS. To our knowledge WWW-NIMBUS is the first interactive multiobjective optimization system on the Internet. The main principles of its implementation are centralized computing and a distributed interface. Typically, the delivery and update of any software is problematic. Limited computer capacity may also be a problem. Via the Internet, there is only one version of the software to be updated and any client computer has the capabilities of a server computer. Further, the World-Wide Web (WWW) provides a graphical …
Multi-party metering: An architecture for privacy-preserving profiling schemes
2013
Several privacy concerns about the massive deploy- ment of smart meters have been arisen recently. Namely, it has been shown that the fine-grained temporal traces generated by these meters can be correlated with different users behaviors. A new architecture, called multi-party metering, for enabling privacy-preserving analysis of high-frequency metering data without requiring additional complexity at the smart meter side is here proposed. The idea is to allow multiple entities to get a share of the high-frequency metering data rather than the real data, where this share does not reveal any information about the real data. By aggregating the shares provided by different users and publishing …
The Perceived Role of Technology in Career Guidance among Practitioners Who are Experienced Internet Users
2011
The increasing use of technology is placing new demands on career guidance practitioners. This article examines what changes, if any, have occurred in the perceptions of guidance practitioners regarding their role and the role of the internet in meeting guidance goals and delivering career guidance services. The data were collected in focus groups in 2001–2002 and a follow-up study in 2010. A total of seven focus groups were held. The data were analysed using combined methods. The results indicated that practitioners now observe that the need for differentiated service delivery modes is more explicit due to varied levels of readiness in decision-making and ICT literacy.
Compensating Need Satisfaction across Life Boundaries: A Daily Diary Study
2017
Self-determination theory suggests that satisfaction of an individual's basic psychological needs (for competence, autonomy, and relatedness) is a key for well-being. This has gained empirical support in multiple life domains, but little is known about the way that need satisfaction interacts between work and home. Drawing from ideas of work–home compensation, we expect that the benefits of need satisfaction in the home domain are reduced when needs are satisfied in the work domain. We tested this hypothesis with a daily diary study involving 91 workers. Results showed that individuals particularly benefit from satisfaction of their need for competence in the home domain when it is not sati…
iCanCope With Pain: Cultural Adaptation and Usability Testing of a Self-Management App for Adolescents With Persistent Pain in Norway.
2019
Background: Persistent or chronic pain is a common health problem among adolescents. Thus, it is important that they receive evidence-based strategies for symptom management. iCanCope with Pain is a mobile phone app designed to help adolescents cope with chronic pain. The app comprises 5 evidence- and theory-based features: (I) symptom trackers for pain, sleep, mood, physical function, and energy; (II) goal setting to improve pain and function; (III) a coping toolbox of pain self-management strategies; (IV) social support; and (V) age-appropriate pain education. The iCanCope with Pain app is based on theory, identified health care needs, and current best practices for pain self-management. …
A visual framework to create photorealistic retinal vessels for diagnosis purposes
2020
The methods developed in recent years for synthesising an ocular fundus can be been divided into two main categories. The first category of methods involves the development of an anatomical model of the eye, where artificial images are generated using appropriate parameters for modelling the vascular networks and fundus. The second type of method has been made possible by the development of deep learning techniques and improvements in the performance of hardware (especially graphics cards equipped with a large number of cores). The methodology proposed here to produce high-resolution synthetic fundus images is intended to be an alternative to the increasingly widespread use of generative ad…
Dynamic interface for machine vision systems
2002
Iconic programming intends to provide expressive tools to implement, to debug, and to execute programs. For this purpose, visual languages need pictorial constructs and metaphors to guide the design of algorithms in interactive fashion. In the paper a new class of dynamic visual interfaces, named DIVA (Dynamic Interface for Visual Applications), is introduced, its properties are described, and an application to visual compilers in a multi-processors system dedicated to image analysis is given. Moreover, a formal definition of dynamic icon (DI) is also given.
Citizen experts in participatory governance: Democratic and epistemic assets of service user involvement, local knowledge and citizen science
2021
Initiatives that attribute expert status to ‘ordinary citizens’ proliferate in a range of societal realms and are generally celebrated for ‘democratising expertise’. By tapping new sources of knowledge and participation simultaneously, such ‘citizen expertise’ practices seem to provide responses to the contemporary decline of trust in political elites and traditional experts that seriously challenges the legitimacy of democratic policy-making. This study distinguishes between three quintessential types of citizen expertise (‘local knowledge’, ‘service user involvement’ and ‘citizen science’) and, from an integrated perspective, critically discusses the value of citizen expertise for public…
