A 3D Non-Stationary Cluster Channel Model for Human Activity Recognition
(Journal article; Peer reviewed, 2019)This paper proposes a three-dimensional (3D) non- stationary fixed-to-fixed indoor channel simulator model for human activity recognition. The channel model enables the formulation of temporal variations of the received ... -
A Case Study of the Technology Use and Information Flow at a Hospital-driven Telemedicine Service
(Journal article; Peer reviewed, 2017)Health care services face the challenge of providing individualised treatment to a growing ageing population prone to chronic conditions and multi-morbidities. The research project Patients and Professionals in Productive ... -
A Cluster Analysis of Stock Market Data Using Hierarchical SOMs
(Chapter; Peer reviewed, 2016)The analysis of stock markets has become relevant mainly because of its financial implications. In this paper, we propose a novel methodology for performing a structured cluster analysis of stock market data. Our proposed ... -
A co-writing development approach to wikis: Pedagogical issues and implications
(Journal article; Peer reviewed, 2011)Wikis are promoted as collaborative writing tools that allow students to transform a text into a collective document by information sharing and group reflection. However, despite the promising collaborative capabilities ... -
A collaborative writing approach to wikis: Design, implementation, and evaluation
(Journal article; Peer reviewed, 2011)Wikis provide teachers with potentially significant opportunities for creating socially engaged tasks that require active student participation and collaboration. Wikis allow students to work together to develop content ... -
A critical review on supply chain risk - Definition, measure and modeling
(Journal article; Peer reviewed, 2015) -
A formal proof of the ε-optimality of absorbing continuous pursuit algorithms using the theory of regular functions
(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
(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
(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 general framework for group authentication and key exchange protocols
(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 geometrical three-ring-based model for MIMO mobile-to-mobile fading channels in cooperative networks
(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
(Journal article; Peer reviewed, 2017) -
A hierarchical learning scheme for solving the Stochastic Point Location problem
(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
(Peer reviewed; Journal article, 2016) -
A new frontier in novelty detection : Pattern recognition of stochastically episodic events
(Lecture Notes in Computer Science; no. 6591, Chapter; Peer reviewed, 2011)A particularly challenging class of PR problems in which the, generally required, representative set of data drawn from the second class is unavailable, has recently received much consideration under the guise of One-Class ... -
A new paradigm for pattern classification: Nearest Border Techniques
(Lecture Notes in Computer Science;8272, Chapter; Peer reviewed, 2013)There are many paradigms for pattern classification. As opposed to these, this paper introduces a paradigm that has not been reported in the literature earlier, which we shall refer to as the Nearest Border (NB) paradigm. ... -
A Non-Isovelocity Geometry-Based Underwater Acoustic Channel Model
(Journal article; Peer reviewed, 2017) -
A Non-Stationary Channel Model for the Development of Non-Wearable Radio Fall Detection Systems
(Journal article; Peer reviewed, 2018)The emerging non-wearable fall detection systems rely on processing radio waves reflected off the body of the home user who has no active interaction with the system, increasing the user privacy and acceptability. This ... -
A Non-Stationary Mobile-to-Mobile Channel Model Allowing for Velocity and Trajectory Variations of the Mobile Stations
(Journal article; Peer reviewed, 2017) -
A Non-Stationary Mobile-to-Mobile Channel Model Allowing for Velocity and Trajectory Variations of the Mobile Stations
(Journal article; Peer reviewed, 2017)In mobile-to-mobile (M2M) communication systems, both the transmitter and the receiver are moving with a certain velocity, which is usually assumed to be constant over time. However, in realistic propagation scenarios, the ...
