Scattering in a quantum dot: the role of resonances
(Journal of Physics: Condensed Matter;25(31), Journal article; Peer reviewed, 2013-07-09)The dynamics of a system in which an electron is incident on a populated quantum dot is studied by resolving the time dependence of the system. Specifically, one electron is initially at rest in the ground state of the ... -
An Interface for reducing errors in intravenous drug administration
(Lecture Notes in Electrical Engineering;260, 3-12, Journal article; Peer reviewed, 2013-08)Input errors occur with drug infusion pumps when nurses or technicians incorrectly input the prescribed therapy through the control panel. Such number copying tasks are cognitively and visually demanding, errors are easily ... -
An error tolerant memory aid for reduced cognitive load in number copying tasks
(Lecture Notes in Computer Science;8010, Journal article; Peer reviewed, 2013-08)Number copying tasks are still common despite increased digitalization of services. Number copying tasks are cognitively and visually demanding, errors are easily introduced and the process is often perceived as laborious. ... -
Gravitational Entropy and Inflation
(Entropy;15 (9), Journal article; Peer reviewed, 2013-09-04)The main topic of this paper is a description of the generation of entropy at the end of the inflationary era. As a generalization of the present standard model of the Universe dominated by pressureless dust and a Lorentz ... -
Universe models with negative bulk viscosity
(Astrophysics and Space Science;347 (2), Journal article; Peer reviewed, 2013-10)The concept of negative temperatures has occasionally been used in connection with quantum systems. A recent example of this sort is reported in the paper of S. Braun et al. [Science 339, 52 (2013)], where an attractively ... -
Crawling JavaScript websites using WebKit - with application to analysis of hate speech in online discussions
(NIK: Norsk Informatikkonferanse;2013, Journal article; Peer reviewed, 2013-11)JavaScript Client-side hidden web pages (CSHW) contain dynamic material created as a result of specific user activities. The number of CSHW websites is increasing. Crawling the so-called Hidden Web is challenging, particularly ... -
Detecting Threats of Violence in Online Discussions Using Bigrams of Important Words
(IEEE Joint;, Chapter; Peer reviewed, 2014)Making violent threats towards minorities like immigrants or homosexuals is increasingly common on the Internet. We present a method to automatically detect threats of violence using machine learning. A material of ... -
Building sentiment Lexicons applying graph theory on information from three Norwegian thesauruses
(Norsk Informatikkonferanse;2014, Journal article; Peer reviewed, 2014)Sentiment lexicons are the most used tool to automatically predict sentiment in text. To the best of our knowledge, there exist no openly available sentiment lexicons for the Norwegian language. Thus in this paper ... -
Before and after Lightfoot/León. Using rich pictures to illustrate an educational journey through the world of opera and ballet
(FORMakademisk;7(5), Journal article; Peer reviewed, 2014)In this article, we describe part of an action research project carried out during a classroom-based art course at a higher education institution. We gave the students themed collaborative drawing assignments, with the ... -
A novel strategy for solving the stochastic point location problem using a hierarchical searching scheme
(Journal article; Peer reviewed, 2014)Stochastic point location (SPL) deals with the problem of a learning mechanism (LM) determining the optimal point on the line when the only input it receives are stochastic signals about the direction in which it should ... -
Evolutionary optimization algorithms for sunlight-based positioning sensor networks
(International Journal of Distributed Sensor Networks;Article ID 564072, Journal article; Peer reviewed, 2014)The sunlight intensity-based global positioning system (SGPS) is able to geolocate outdoor objects by means of the sunlight intensity detection. This paper presents the integration of SGPS into a sensor network in order ... -
