Peptide classification using optimal and information theoretic syntactic modeling
(Journal article; Peer reviewed, 2010)We consider the problem of classifying peptides using the information residing in their syntactic representations. This problem, which has been studied for more than a decade, has typically been investigated using ... -
Language Detection and Tracking in Multilingual Documents Using Weak Estimators
(Chapter; Peer reviewed, 2010)This paper deals with the extremely complicated problem of language detection and tracking in real-life electronic (for example, in Word-of-Mouth (WoM)) applications, where various segments of the text are written in ... -
Accessibility of eGovernment Web Sites: Towards a Collaborative Retrofitting Approach
(Lecture Notes in Computer Science;6179, Chapter; Peer reviewed, 2010)Accessibility benchmarking is efficient to raise awareness and initiate competition. However, traditional benchmarking is of little avail when it comes to removing barriers from eGovernment web sites in practice. Regulations ... -
Broadband internet access via multi-hop wireless mesh networks: design, protocol and experiments
(Journal article; Peer reviewed, 2010)While bandwidth for Internet access in urban areas is steadily increasing in recent years, many rural areas are still suffering from the effect of the digital divide. This paper presents a broadband Internet access paradigm ... -
Secure, dependable and publicly verifiable distributed data storage in unattended wireless sensor networks
(Journal article; Peer reviewed, 2010)In unattended wireless sensor networks (UWSNs), sensed data are stored locally or at designated nodes and further accessed by authorized collectors on demand. This paradigm is motivated by certain scenarios where historical ... -
Fault-tolerant routing in adversarial mobile ad hoc networks: an efficient route estimation scheme for non-stationary environments
(Journal article; Peer reviewed, 2010)Designing routing schemes that would successfully operate in the presence of adversarial environments in Mobile Ad Hoc Networks (MANETs) is a challenging issue. In this paper, we discuss fault-tolerant routing schemes ... -
An Exact Solution for the Level-Crossing Rate of Shadow Fading Processes Modelled by Using the Sum-of-Sinusoids Principle
(Journal article; Peer reviewed, 2010)The focus of this paper is on the higher order statistics of spatial simulation models for shadowing processes. Such processes are generally assumed to follow the lognormal distribution. The proposed spatial simulation ... -
Optimal sampling for estimation with constrained resources using a learning automaton-based solution for the nonlinear fractional knapsack problem
(Journal article; Peer reviewed, 2010)While training and estimation for Pattern Recognition (PR) have been extensively studied, the question of achieving these when the resources are both limited and constrained is relatively open. This is the focus of this ... -
Mobile-to-mobile fading channels in amplify-and-forward relay systems under line-of-sight conditions: statistical modeling and analysis
(Journal article; Peer reviewed, 2010)This paper deals with the modeling and analysis of narrowband mobile-to-mobile (M2M) fading channels for amplify-and-forward relay links under line-of-sight (LOS) conditions. It is assumed that a LOS component exists in ... -
Cooperative MAC design in multi-hop wireless networks-Part II: When source and destination are two-hops away from each other
(Journal article; Peer reviewed, 2010)Ubiquitous and pervasive computing and networking are envisaged as part of the future 5G wireless communication landscape where devices which are multi-hops away from each other are connected in a cooperative way. In this ... -
Editorial: Special issue on "5G workshop on networks, services and applications" : topics from the 1st Joint Workshop between Center for TeleInFrastruktur (CTIF), Denmark and Center for Wireless Innovation (CWI), Norway, October 8, 2009, Aalborg, Denmark
(Journal article; Peer reviewed, 2010)The first joint workshop between Center for TeleInFrastruktur (CTIF), Denmark and Center for Wireless Innovation (CWI), Norway, was held in Aalborg, Denmark on October 8, 2009, focusing on yet undefined term, "5G mobile ... -
Supporting fine-grained generative model-driven evolution
(Journal article; Peer reviewed, 2010)In the standard generative Model-driven Architecture (MDA), adapting the models of an existing system requires re-generation and restarting of that system. This is due to a strong separation between the modeling environment ... -
Cooperative MAC design in multi-hop wireless networks: Part I: When source and destination are within the transmission range of each other
(Journal article; Peer reviewed, 2010)Cooperative communication is regarded as a promising technology in future 5G wireless networks to enhance network performance by exploiting time and/or space diversity via distributed terminals. In this paper, we propose ... -
Solving Non-Stationary Bandit Problems by Random Sampling from Sibling Kalman Filters
(Lecture Notes in Computer Science ; 6098, Chapter; Peer reviewed, 2010)The multi-armed bandit problem is a classical optimization problem where an agent sequentially pulls one of multiple arms attached to a gambling machine, with each pull resulting in a random reward. The reward distributions ... -
