A Trusted Hybrid Learning Approach to Secure Edge Computing

2021

Securing edge computing has drawn much attention due to the vital role of edge computing in Fifth Generation (5G) wireless networks. Artificial Intelligence (AI) has been adopted to protect networks against attackers targeting the connected edge devices or the wireless channel. However, the proposed detection mechanisms could generate a high false detection rate, especially against unknown attacks defined as zero-day threats. Thereby, we propose and conceive a new hybrid learning security framework that combines the expertise of security experts and the strength of machine learning to protect the edge computing network from known and unknown attacks, while minimizing the false detection rat…

Structural disorder and electronic hybridization in NicMg1−cO solid solutions probed by XANES at the oxygen K edge

2007

A series of NicMg1−cO solid solutions has been studied for the first time looking at the structural disorder by means of x-ray absorption near-edge-structure (XANES) spectroscopy at the oxygen K edge. The experimental XANES signals were analysed within the full multiple scattering formalism and were interpreted taking into account clusters of up to 15 coordination shells around an absorbing oxygen atom. The substitution of nickel atoms by magnesium atoms results in a dramatic decrease of the empty density of states in the conduction band close to the Fermi level due to an exchange of the 3d(Ni)–2p(O) interaction with 3p(Mg)–2p(O). Besides, a simultaneous small decrease of the 3d(Ni)–2p(O) h…

Understanding and managing process interaction in IS development projects

2012

Published version of an article from the book: Nordic Contributions in IS Research. Also available on SpringerLink:http://dx.doi.org/10.1007/978-3-642-32270-9_2 Software-based information systems must be developed and implemented as a part of business change. This is a major challenge, since business change and the development of software-based information systems usually are performed in separate processes. Thus, there is a need to understand and manage the relationship between these two kinds of processes. In this paper we draw on a longitudinal case study. We suggest a framework to analyze the case as interaction between software development processes and organizational change processes.…

DYNAMIC SEMANTIC USER PROFILING FROM IMPLICIT WEB NAVIGATION DATA

2014

International audience; On the Web, pages are often dynamically generated and allow publishers to individually adapt contents to each viewer. Underlying systems must correctly understand the user's context - crucial especially in the case of online advertisement placement. The article at hand describes our proposition of a novel profiling system, adapted to the special needs of digital advertising. Based on Semantic Web Technologies, the MindMinings system relies on an ontology to enable thorough understanding of each user's context and needs. The underlying ontology structure also provides enhanced interoperability with semantically annotated knowledge resources, notably vocabularies from …

The paradoxical management of service skills

2015

This paper focuses on service skills which are mobilized by front office agents when they are involved with customers. These skills are most of the time tacit. We consider that the way in which firms recognize these skills and contribute to their development is an important management issue. It is all the more important that a lot of jobs combine poor levels of qualification and highly situated skills.

Impact of psychic distance to the internationalization behavior of knowledge-intensive SMEs

2009

Purpose: The purpose of this paper is to investigate the internationalization behavior of knowledge-intensive small- to medium-sized enterprises (SMEs) by using macro-level psychic distance indicators and managers' perceptions of psychic distance. Design/methodology/approach: This study uses both quantitative and qualitative approaches. In the quantitative approach, the impact of psychic distance to the internationalization behavior is analyzed by using bivariate correlation analysis. The qualitative case study approach is employed to investigate managers' perceptions of psychic distance as regards market entries. Findings: Findings of this study indicate that psychic distance has an impact…

A Task Execution Scheme for Dew Computing with State-of-the-Art Smartphones

2021

The computing resources of today’s smartphones are underutilized most of the time. Using these resources could be highly beneficial in edge computing and fog computing contexts, for example, to support urban services for citizens. However, new challenges, especially regarding job scheduling, arise. Smartphones may form ad hoc networks, but individual devices highly differ in computational capabilities and (tolerable) energy usage. We take into account these particularities to validate a task execution scheme that relies on the computing power that clusters of mobile devices could provide. In this paper, we expand the study of several practical heuristics for job scheduling including executi…

Joint attention behaviour in remote collaborative problem solving : exploring different attentional levels in dyadic interaction

2021

AbstractThe current article describes an exploratory study that focussed on joint attention behaviour—the basis of interaction predicting productive collaboration—to better understand collaborative problem solving, particularly its social aspects during remote dyadic interaction. The study considered joint attention behaviour as a socio-linguistic phenomenon and relied on detailed qualitative interaction analysis on event-related measures of multiple observational data (i.e. log files, eye-tracking data). The aim was to illustrate and exemplify how the diverse attentional levels of joint attention behaviour (i.e. monitoring, common, mutual and shared attention) delineated by Siposova and Ca…
