Stochastic Graph Filtering Under Asymmetric Links in Wireless Sensor Networks
(Chapter; Peer reviewed, 2018)Wireless sensor networks (WSN s) are often characterized by random and asymmetric packet losses due to the wireless medium, leading to network topologies that can be modeled as random, time-varying and directed graphs. ... -
Stochastic Learning-Based Estimation Methods for Pattern Recognition and Its Application to Topic Detection and Tracking
(Master thesis, 2008)Every Pattern Recognition (PR) problem involves a training and a testing phase. In the training phase, the system is presented with samples, using which the distribution (also called the classconditional distribution), ... -
Streamwater responses to reduced nitrogen deposition at four small upland catchments in Norway
(Peer reviewed; Journal article, 2020)Reduced emissions of nitrogen (N) in Europe have resulted in decreasing atmospheric deposition since 1990. Long-term data (1988–2017) from four small Norwegian catchments located along gradients in N deposition, rainfall, ... -
Strongly Extreme Points and Approximation Properties
(Journal article; Peer reviewed, 2018) -
Structural vibration control for a class of connected multistructure mechanical systems
(Journal article; Peer reviewed, 2012)A mathematical model to compute the overall vibrational response of connected multistructure mechanical systems is presented. Using the proposed model, structural vibration control strategies for seismic protection of ... -
Student meaning making in elementary algebra teaching : An in-depth study of classrooms in four countries
(Doctoral dissertations at the University of Agder; no. 258, Doctoral thesis, 2020)The research presented in this thesis is based on observations and analyses of classroom data from four countries. The data were collected through a collaboration of local research teams in Finland, Norway, Sweden and the ... -
Student Motivation in Mathematical Problem-Solving Tasks
(Master thesis, 2022)Students from the school are our future. Therefore, it is essential that teachers, who are part of the school, encourage the students to use their full potential. To do this, teachers need to make their students find the ... -
Students’ perception of infinity : Perception, obstacles, conception
(Master thesis, 2017)Several studies in mathematics education have shown that students face significant difficulties for understanding the concept of infinity. The purpose of this study is to suggest an explanation of how students understand ... -
Students’ perceptions of the relevance of mathematics in an Ethiopian preparatory school : Doctoral Dissertation at the University of Agder
(Doctoral dissertations at University of Agder, Doctoral thesis, 2019) -
Studie av ulike Mother Wavelets til bruk innen kantdeteksjon av blodårer i ultralydbilder
(Master thesis, 2003)Kantdeteksjon er en viktig forutsetning for at operasjoner skal kunne gjennomføres på en tryggest mulig måte. Kirurgene må vite hvor blodårene er for å unngå og gjøre skade på pasienten. Metodene som blir brukt til ... -
Study and performance evaluation of transport layer protocols over heterogeneous radio and satellite networks
(Master thesis, 2006)Satellites have for some years made it possible to transfer data over long distances, and from desolated locations. Due to their natural broadcast ability they have some major advantages compared to terrestrial links. This ... -
Study Approaches in Higher Education Mathematics : Investigating the Statistical Behaviour of an Instrument Translated into Norwegian

Study of aspects in electronic patient journal relevant to the medical office agreement
(Master thesis, 2003)Keeping track of the condition of a patient is and always will be important in order for a doctor to give the best diagnosis and keeping the patient as healthy as possible. Earlier the patient journals were stored at the ... -
A study of possible use of Radio Frequency Identification(RFID) in Abu Dhabi Sewerage Directorate
(Master thesis, 2004)This report describes the possible use of RFID in a business case such as the Sewerage Directorate at Abu Dhabi Municipality & Town Planning Department. The prototype phase is developed using the ethnographic study which ... -
A study of the influence of shadowing on the statistical properties of the capacity of mobile radio channels
(Journal article; Peer reviewed, 2009)This paper studies the influence of shadowing on the statistical properties of the channel capacity. The problem is addressed by using a Suzuki process as an appropriate statistical channel model for land mobile terrestrial ... -
A study of wavelets combined, if desired, with other methods for use in edge sharpening of ultrasound images
(Master thesis, 2003)The increased use of laparoscopic surgery has resulted in a growing interest in use of ultrasounds. Ultrasounds do not have any known side effects, and it provides the surgeon with real-time imaging. In spite of its ... -
A study of Wavelets for edge detection of anatomical structure on medical images
(Master thesis, 2004)Osteoporosis is a bone disease that makes your bone crumble away. To find out how thick your bone structure is, medical personnel uses x-ray images and measure the thickness of your bones. Today this is done manually by ... -
A study on permanent deformation and fatigue damage interaction in asphalt concrete
(Peer reviewed; Journal article, 2023)The dominant load-induced damages, permanent deformation (PD) and fatigue cracking (F), are traditionally predicted separately by taking temperature as a variable of departure. This paper presents an experimental study of ... -
