A Hierarchical Detection and Response System to Enhance Security Against Lethal Cyber-Attacks in UAV Networks
2018
International audience; Unmanned aerial vehicles (UAVs) networks have not yet received considerable research attention. Specifically, security issues are a major concern because such networks, which carry vital information, are prone to various attacks. In this paper, we design and implement a novel intrusion detection and response scheme, which operates at the UAV and ground station levels, to detect malicious anomalies that threaten the network. In this scheme, a set of detection and response techniques are proposed to monitor the UAV behaviors and categorize them into the appropriate list (normal, abnormal, suspect, and malicious) according to the detected cyber-attack. We focus on the m…
A robust aerial image registration method using Gaussian mixture models
2014
Aerial image registration is one of the bases in many aerospace applications, such as aerial reconnaissance and aerial mapping. In this paper, we propose a novel aerial image registration algorithm which is based on Gaussian mixture models. First of all, considering the characters of the aerial images, the work uses a shape feature detector which computes the boundaries of regions with nearly the same gray-value to extract invariant feature. Then, a Gaussian mixture models (GMM) based image registration model is built and solved to estimate the transformation matrix between two aerial images. Furthermore, the proposed method is applied on real aerial images, and the results demonstrate the …
Estimating economic severity of Air Traffic Flow Management regulations
2021
The development of trajectory-based operations and the rolling network operations plan in European air traffic management network implies a move towards more collaborative, strategic flight planning. This opens up the possibility for inclusion of additional information in the collaborative decision-making process. With that in mind, we define the indicator for the economic risk of network elements (e.g., sectors or airports) as the expected costs that the elements impose on airspace users due to Air Traffic Flow Management (ATFM) regulations. The definition of the indicator is based on the analysis of historical ATFM regulations data, that provides an indication of the risk of accruing dela…
Special Issue of Journal of Manufacturing Processes on Advancing Manufacturing Processes Research at NAMRC 46
2018
During the refereeing process of papers submitted to NAMRC 46 this year, nine high-quality papers have been selected and fast-tracked to a special issue of Journal of Manufacturing Processes (JMP) entitled “Advancing Manufacturing Processes Research at NAMRC 46”. The selection of the fast-track papers was based on authors’ preferences, quality of the papers, reviewers’ recommendations, Track Chairs’ picks, pre-selection by the Chair of NAMRI/SME Scientific Committee, and final approval by the JMP Editor. The nine papers published in JMP are therefore excluded from the Proceedings of NAMRC 46 in Procedia Manufacturing. Nevertheless, these papers are presented in person at NAMRC 46. Details o…

Artificial Neural Networks in Sports: New Concepts and Approaches
2001
Artificial neural networks are tools, which - similar to natural neural networks - can learn to recognize and classify patterns, and so can help to optimise context depending acting. These abilitie...
Developing a supplier performance analysis model : case study: Aker MH supplier performance
2012
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2012 This master thesis focuses on the use Data Envelopment Analysis (DEA) for measuring supplier performance. Goal of the study is to apply a mathematical model for supplier performance measurement which would be able to handle multi-criteria. To test the model in practice, cooperation was established with case study firm (Aker Maritime Hydraulics), which is providing drilling engineering solutions to Oil & Gas industry. Proposing the model for measuring performance of existing suppliers not only demonstrates how DEA can be applied, but also sets the grounds for supplier performance improvement process in a case study firm. …
The implementation of NFC-based mobile payment in Norway : a case study of the emerging NFC business ecosystem in Norway
2013
Masteroppgave i økonomi og administrasjon - Universitetet i Agder 2013 This master thesis looks at the emergence of mobile payment in Norway with a focus on NFC technology. NFC based mobile payments represent a relative new technology that can be used in a relative new business area, which is that of mobile payments. The move towards mobile payment can be the beginning of a shift from traditional payment forms, such as cash and payment cards, to a new and modern way of conduction payments, using your own personal mobile phone. For the unobservant eye, the idea can seem like a scenario taken out of a Hollywood movie. The reality is that the technology already surrounds us in our everyday lif…
Batteries for Aerospace: A Brief Review
2018
This paper presents a brief overview on batteries for aerospace application. In particular, More Electric Aircraft (MEA) and All Electric Aircraft (AEA) concepts are introduced at first, together with their main advantages and drawbacks. Subsequently, opportunities and issues related to the employment of batteries on aircrafts are presented and briefly discussed. Reference is then made to aircraft power system architectures and battery technologies, as well as on the state-of-the-art of battery management systems, state-of-charge and state-of-health estimations, and thermal management.
