A formal proof of the ε-optimality of absorbing continuous pursuit algorithms using the theory of regular functions
Zhang, Xuan; Granmo, Ole-Christoffer; Oommen, B. John; Jiao, Lei (Journal article; Peer reviewed, 2014)The most difficult part in the design and analysis of Learning Automata (LA) consists of the formal proofs of their convergence accuracies. The mathematical techniques used for the different families (Fixed Structure, ... -
A Framework for Activity Monitoring and Fall Detection Based on the Characteristics of Indoor Channels
Abdelgawwad, Ahmed; Pätzold, Matthias Uwe (Journal article; Peer reviewed, 2018)This paper concerns the Doppler power spectrum of three-dimensional non-stationary indoor fixed-to- fixed channels with moving people. In this paper, we model each moving person as a moving scatterer with time-variant (TV) ... -
A framework for assessing the condition of crowds exposed to a fire hazard using a probabilistic model
Radianti, Jaziar; Granmo, Ole-Christoffer (Journal article; Peer reviewed, 2014)Allocating limited resources in an optimal manner when rescuing victims from a hazard is a complex and error prone task, because the involved hazards are typically evolving over time; stagnating, building up or diminishing. ... -
A Framework for Improving Intrusion Detection Systems by Combining Artificial Intelligence and Situational Awareness
Lindemann, Daniel; van der Meij, Yaguel (Master thesis, 2022)The vast majority of companies do not have the requisite tools and analysis to make use of the data obtained from security incidents in order to protect themselves from attacks and lower their risk. Intrusion Detection ... -

A frequency compensation algorithm of four-wheel coherence random road
Feng, Jun; Zhang, Xinjie; Guo, Konghui; Ma, Fangwu; Karimi, Hamid Reza (Journal article; Peer reviewed, 2013)The road surface roughness is the main source of kinematic excitation of a moving vehicle, which has an important influence on vehicle performance. In recent decades, random road models have been widely studied, and a ... -
A fuzzy logic approach to modeling a vehicle crash test
Pawlus, Witold; Karimi, Hamid Reza; Robbersmyr, Kjell G. (Journal article; Peer reviewed, 2012)This paper presents an application of fuzzy approach to vehicle crash modeling. A typical vehicle to pole collision is described and kinematics of a car involved in this type of crash event is thoroughly characterized. The ... -
A general framework for group authentication and key exchange protocols
Yang, Huihui; Jiao, Lei; Oleschchuk, Vladimir A. (Lecture Notes in Computer Science;8352, Chapter; Peer reviewed, 2014)In this paper, we propose a novel framework for group authentication and key exchange protocols. There are three main advantages of our framework. First, it is a general one, where different cryptographic primitives can ... -
A Generative Adversarial Approach for Packet Manipulation Detection
Kamphaug, Åsmund (Master thesis, 2018)Over the years, machine learning has been used together with intrusion detection systems to protect networks against different threats. The evolution of machine learning has exploded and there are new types of of machine ... -
A geometrical three-ring-based model for MIMO mobile-to-mobile fading channels in cooperative networks
Talha, Batool; Pätzold, Matthias (Journal article; Peer reviewed, 2011)This paper deals with the modeling and analysis of narrowband multiple-input multiple-output (MIMO) mobile-to-mobile (M2M) fading channels in relay-based cooperative networks. In the transmission links from the source ... -
A Geometry-Based Underwater Acoustic Channel Model Allowing for Sloped Ocean Bottom Conditions
Naderi, Meisam; Pätzold, Matthias Uwe; Hicheri, Rym; Youssef, Neji (Journal article; Peer reviewed, 2017) -
A Global Perspective on Microplastic Concentrations and Characteristics in Sediment and Biota in Marine Coastal Areas
Johnsen, Emilie (Master thesis, 2023)Microplastic (MP, < 5 mm) has become an omnipresent environmental pollutant due to inappropriate management since the invention of plastic during the 1800s. MPs are now detected in all environmental matrices, with marine ... -
A hierarchical learning scheme for solving the Stochastic Point Location problem
Yazidi, Anis; Granmo, Ole-Christoffer; Oommen, B. John; Goodwin, Morten (Lecture Notes in Computer Science;7345, Chapter; Peer reviewed, 2012)This paper deals with the Stochastic-Point Location (SPL) problem. It presents a solution which is novel in both philosophy and strategy to all the reported related learning algorithms. The SPL problem concerns the task ... -
A Highly Flexible Trajectory Model Based on the Primitives of Brownian Fields---Part II: Analysis of the Statistical Properties
Borhani, Alireza; Pätzold, Matthias Uwe (Peer reviewed; Journal article, 2016) -
A knowledge-based master model approach exemplified with jet engine structural design
