Temporal changes in parameters describing stochastic population dynamics
(Master thesis, 2011)The solution of a stochastic differential equation with temporally dependent parameters is the basis for the following analysis of stochastic population dynamics with temporal changes in the parameters. A discrete density ... -
Ten years of Methods in Ecology and Evolution
(Journal article; Peer reviewed, 2020)The start of 2020 marks the end of the first decade of Methods in Ecology and Evolution. When we launched the journal in 2010, we did so because of feedback from the community that there was a need for a journal that ... -
Tension during parametric excitation in submerged vertical taut tethers
(Journal article; Peer reviewed, 2017)The construction of a suspension bridge with floating pylons or a submerged floating tunnel requires the installation of a mooring system. The option of taut vertical tethers, similar to those used in tension-leg platforms, ... -
Tensor-product coaction functors
(Peer reviewed; Journal article, 2020)Recent work by Baum et al. [‘Expanders, exact crossed products, and the Baum–Connes conjecture’, Ann. K-Theory 1(2) (2016), 155–208], further developed by Buss et al. [‘Exotic crossed products and the Baum–Connes conjecture’, ... -
Testing equality of the success probabilities in two independent binomial distributions
(Master thesis, 2016)The aim of this thesis is to compare the power of tests of equality of the success probabilities in two independent binomial distributions for different sample sizes and for different significance levels. The null hypothesis ... -
Testing the effect of quantitative genetic inheritance in structured models on projections of population dynamics
(Peer reviewed; Journal article, 2019)Global climate change is altering the timing of life history events for species living in seasonal environments. These shifts in phenology can lead to the disruption of interspecific relationships with implications for ... -
Text Classification via Topological Data Analysis
(Master thesis, 2023)Moderne generative språkmodeller som ChatGPT har en bemerkelsesverdig evne til å generere tekster som er vanskelige å skille fra menneskeskrevne tekster. Topologisk dataanalyse (TDA) brukes til å studere formen på data, ... -
Text-Video Retrieval Using Encoder and Cross Encoder Models
(Master thesis, 2022)I denne oppgaven undersøker vi hvordan dyp læring med enkodermodeller kan brukes til videosøk. Motivasjonen for å bruke nettopp enkodermodeller er den store suksessen de har hatt på flere tekst-bildeoppgaver og deres ... -
The 2-Kronecker Quiver and Systems of Linear Differential Equations
(Master thesis, 2013)We present a way of classifying all the indecomposable representations of the 2-Kronecker quiver over an algebraically closed field. We do this mainly by constructing classes of irregular indecomposable representations by ... -
The 4 Subspace Problem
(Master thesis, 2008)We present a complete solution to the 4 subspace problem in the generality of an algebraically closed eld. We do this by means of Auslander-Reiten theory and give the Auslander-Reiten quiver of the extended $D_4$ Dynkin ... -
The 4 Subspace Problem
(Bachelor thesis, 2020)Fireunderromsproblemet handlar om å finne alle ikkje-dekomponerbare system som består av eit vektorrom med fire underrom. Denne avhandlinga oversetter uttrykket system om til underromsrepresentasjonar av stjernekogger og ... -
The Algebraic Bivariant Connes-Chern Character
(Master thesis, 2017)In this thesis we present many properties of bivariant periodic cyclic homology with the purpose of then constructing two bivariant Connes-Chern characters from algebraic versions of Kasparov's KK-theory with values in ... -
The Analysis of Continuous Mark-Recapture Data
(Doctoral thesis, 2006)The purpose of this thesis is to develop a general methodology for the analysis of continuously sampled data from open populations. The thesis consists of four parts and one appendix. The four parts may be read independently ... -
The argument principle and its first applications.
(Master thesis, 2023)I denne masteroppgaven skal vi utforske opphavet til argumentprinsippet og dets utvikling over tid. Vi vil også undersøke noen av nøkkelapplikasjonene, inkludert bruken i studiet av Riemann zeta funksjonen. Mot slutten av ... -
The Arnold Conjecture
(Bachelor thesis, 2020)Arnolds formodning sier at en Hamiltonsk symplektomorfi på en symplektisk mangfoldighet har minst like mange fikspunkter som en funksjon på mangfoldigheten har kritiske punkter. I denne oppgaven gir vi en introduskjon ... -
The Balian–Low theorem and noncommutative tori
(Journal article; Peer reviewed, 2018)We point out a link between the theorem of Balian and Low on the non-existence of well-localized Gabor–Riesz bases and a constant curvature connection on projective modules over noncommutative tori. -
The Balmer Spectrum of the Local Equivariant Stable Homotopy Category
(Master thesis, 2022)Vi introduserer tensor triangulert geometri, med et mål for å regne ut Balmer spektrumet til den lokale 𝐺-ekvivariante stabile homotopi kategorien, for en en- delig gruppe 𝐺. Vi starter ved å definere grunnleggende ... -
The Cauchy problem for a model of immiscible gas flow with large data
(Doctoral Theses at NTNU, 1503-8181; 2009:4, Doctoral thesis, 2009) -
The Choice of screening design
(Journal article; Peer reviewed, 2017)A screening design is an experimental plan used for identifying the expectedly few active factors from potentially many. In this paper, we compare the performances of 3 experimental plans, a Plackett-Burman design, a minimum ...
