A Comparison of Factor Based Methods for Analysing Some Non-regular Designs
Afrifa-Yamoah, Ebenezer (Master thesis, 2016)Non-regular designs have nice properties regarding run economy. However, standard methods of analysing regular designs are not applicable as a results of possible non-orthogonal contrast columns. We investigated three ... -
A Comparison Study of Different Optimizing Criteria and Confounding Patterns For Multi-Level Binary Replacement and Other Designs Used in Computer Experiments
Thalberg, Hege Grøstad (Master thesis, 2011)We have constructed four different types of designs for computer experiments. Thedesign types are based on latin hypercube sampling (LHS), orthogonal arrays (OA), ran-dom sampling and the recently proposed multi-level ... -
A General Face Recognition System
Manikarnika, Achim Sanjay (Master thesis, 2006)In this project a real-time face detection and recognition system has been discussed and implemented. The main focus has been on the detection process which is the first and most important step before starting with the ... -
Active Learning for Data Streams
Cacciarelli, Davide (Doctoral theses at NTNU;2024:186, Doctoral thesis, 2024)As businesses increasingly rely on machine learning models to make informed decisions, the ability to develop accurate and reliable models is critical. However, in many industrial contexts, data annotation represents a ... -
Analysis of Censored Data from Split-Plot Design
Hansen, Marte Nevland (Master thesis, 2015)In reliability theory, there are often data missing due to censoring. Such incomplete datasets are usually difficult to analyse. The exact value of the censored data is not known, but some information exists. That is, the ... -
Analysis of salmon lice count data for production zones 6 and 7 in Norway from 2017 to 2019
Brakestad, Inge Hoven (Master thesis, 2020)Lakselus (Lepeophtheirus salmonis), er ein parasitt som er ei stor utfordring for vill laksefisk og for oppdrettsnæringa. Denne oppgåva er skriven i samarbeid med "Taskforce Lakselus", som er eit FoU-prosjekt, der målet ... -
Assessing some aspects of factor screening with nonnormal responses
Chaudhry, Muhammad Azam; Tyssedal, John Sølve (Journal article; Peer reviewed, 2019)Nonnormally distributed response values, such as count data for instance, create challenges for factor screening. One problem is that variances may vary from run to run. Another is the choice of screening design for such ... -
Bayesianske metodar relevant for jernbanevedlikehald
Nilsen, Jens Morten (Master thesis, 2008)Jernbaneverket ønskjer å utnytte ressursane dei har til vedlikehald best mogleg. Systematisering og lagring av data om svikt og tilstand på dei utallege komponentane som utgjer det norske jernbanenettet i databasen BaneData ... -
Binary Classification of Credit Card Users with Logistic Regression, Gradient Boosted Decision Trees and Deep Learning
Løite, Ask Moe (Master thesis, 2023)En betydelig del av den vestlige befolkningen eier et kredittkort, men mange av disse personene bruker ikke aktivt kortene sine. Denne oppgaven har som mål å undersøke passive kredittkortbrukere hos SpareBank1, og fokuserer ... -
Blocking and analyzing screening designs
Hamre, Yngvild Hole (Doctoral theses at NTNU;2024:220, Doctoral thesis, 2024) -
Can students' attitudes and behaviors be changed by educational interventions? A comparative case study
Gynnild, Vidar; Tyssedal, John Sølve (Peer reviewed; Journal article, 2020)This study examined engineering students’ attitudes and behaviors in a first-year Calculus course. Not surprisingly, High School mathematics and physics grades correlated closely with self-reported Calculus grades, and a ... -
Censored Weibull Distributed Data in Experimental Design
Støtvig, Jeanett Gunneklev (Master thesis, 2014)Give an introduction to experimental design. Investigate how four methods handle Weibull distributed censored data, where the four methods are the quick and dirty method, the maximum likelihood method, single imputation ... -
Chlamydia trachomatis infections in Norway 2004-2006: Testing and treatment patterns among men and women
Ghaderi, Sara (Master thesis, 2009)Background: In Norway, the number of positive tests for Chlamydia Trachomatis (CT) is increasing. Patients with a positive CT test result should be immediately treated with oral antibiotics according to the treatment ... -
A decoupling method for analyzing foldover designs
Hamre, Yngvild Hole; Tyssedal, John Sølve (Journal article; Peer reviewed, 2024)Foldover designs often have attractive properties. Among these is that the effects can be divided into two orthogonal subspaces, one for odd effects and one for even effects. In this paper, we introduce a new method for ... -
Delousing Effect and Welfare Implications of Non-Medicinal Delousing Methods
Middelthon, Martine (Master thesis, 2023)Lakselusen (Lepeophtheirus salmonis) er en parasitt som påvirker velferden til atlanterhavslaksen. De siste årene har det vært økende interesse for å bruke ikke-medikamentelle metoder for å bekjempe lus, men disse behandlingene ... -
Effect of Safe Failures on the Reliability of Safety Instrumented Systems
Kvam, Eva (Master thesis, 2008)Safety instrumented systems (SISs) are of prime importance to the process industry to avoid catastrophic consequences or even loss of human life. The dangerous situations that any equipment may face should be analysed in ... -
Efficiency of Screening Designs with a Small Number of Runs
Hussain, Shahrukh (Master thesis, 2010)Abstract: Two level non-regular designs are widely used in industrial experimentation for factor screening. At the initial stage of experimentation, it is not possible to know in advance which factors are active so it is ... -
