Triangulated categories and localization
(Master thesis, 2012)We study Gabriel-Zisman localization, localization by a multiplicative system and by a null system. We define the triangulated category and the derived category. Finally we describe a scheme for localization from a ... -
Triangulated Categories and Matrix Factorizations
(Master thesis, 2016)In this thesis we study triangulated categories and look at one specific example, the homotopy category of matrix factorizations. First we define categories and functors. Then we introduce additive and triangulated categories ... -
Triangulated Derivators
(Master thesis, 2022)I denne oppgaven definerer vi Kan-utvidelser og introduserer den punktvise konstruksjonen som lar oss definere derivatorer i en passende kontekst. Ved å utvikle teorien om punktede og stabile derivatorer, beviser vi at ... -
Triangulated Derivators and their Calabi-Yau Dimension
(Master thesis, 2021)Vi introduserer teorien bak derivatorer fra perspektivet til homologisk algebra. Først med motivasjon fra deriverte kategorier og kanutvidelser, deretter en nøye gjennomgang av teorien. Vi utvider flere resultater fra ... -
Triangulating Front End Engineering Design Activities with Physiology Data and Psychological Preferences
(Chapter, 2013)lot data from an exploratory triangulation of front end engineering design activities with physiology data and psychological preferences. The aim is to gain more measurement control over engineering design activities by â ... -
Triassic and Jurassic reservoir distribution influenced by Zechstein salt, in a normal fault system near the margins of the Utsira High, South Viking Graben, North Sea
(Master thesis, 2014)During the Triassic and Jurassic periods, structural and stratigraphic development in the margins of the Utsira High, in the South Viking Graben, resulted in the development of depressional mini-basins and the halokinesis ... -
Tribal Knowledge War: A Location-based Pervasive Knowledge War Game
(Master thesis, 2013)In this thesis, we aim to examine the relationship between a game's pervasiveness and its entertainment value, and try to use this relationship to create a game that is both educational and fun to play. It is our hope that ... -
Tribal Rights in the Past and Present: A Study of how Indigenous Groups and the Archaeological Process may impact each othe
(Master thesis, 2020)Det Samiske Folket og Aboriginske Folket har begge vært utsatt for assimilering og undertrykkelser av vestlige nasjoner. Deres kultur, tradisjoner, spark og identitet har vært I fare for å bli utslettet av de Eurosentriske ... -
Tribocorrosion of Diamond Like Carbon (DLC) coatings for biomedical applications
(Master thesis, 2015)Tribocorrosion has arisen as one of the most important material degradation processes in biomedical applications; thus, the improvement of the materials used in hip or knee prosthesis is very relevant. The aim of this ... -
Tribocorrosion properties of 25% Cr super duplex stainless steel
(Master thesis, 2009) -
Tribocorrosion-fatigue (multi-degradation) of stainless steel: A fundamental approach in practical conditions
(Doctoral theses at NTNU;2017:056, Doctoral thesis, 2017)In marine and offshore industry, components and systems are exposed to corrosive media, wear and fatigue simultaneously (i.e. multi-degradation). These setups are vastly operated in critical and demanding conditions and ... -
Triboelectrochemical friction control of W- and Ag-doped DLC coatings in water-glycol with ionic liquids as lubricant additives
(Peer reviewed; Journal article, 2022)In the last years, diamond like carbon (DLC) coatings doped with both carbide forming and non-carbide forming metallic elements have attracted great interest as novel self-lubricating coatings. Due to the inherent properties ... -
Tribological Behavior of Polymer Seal Materials in Water-Based Hydraulic Fluids
(Journal article; Peer reviewed, 2018)In this work, two polymer materials have been tested in a lubricated reciprocating pin-on-plate contact geometry using water-based hydraulic fluids to simulate sliding conditions of seal materials used in offshore equipment. ... -
Tribological Performance of Polymers and Lubricants Used in Offshore Compensating Hydraulic Cylinders
(Master thesis, 2014)The direct-acting (N-line) riser tensioning system is a commonly selected option for riser tensioning on offshore deepwater drilling vessels. As the system operates in the splash zone, it is exposed to a corrosive environment ... -
Tribological Testing of Environmentally Acceptable Lubricants for Maritime Applications
(Master thesis, 2016)In marine applications, such as ship stabilizers, manoeuvring or propulsion systems, a number of mechanical components are situated below the waterline. Due to negative effects of lubricant leakage in marine environments, ... -
Tribologisk undersøkelse: Validering av ThermaSiC-belegg
(Bachelor thesis, 2021)Abstract will be available on 2024-07-01 -
Tribologisk/material teknologisk studie: Anvendelse av Termisk Sprøytet ThermaSiC som Slitasjebelegg
(Bachelor thesis, 2020)Abstract will be available on 2023-06-20 -
Tribology at High Temperature and Pressure
(Master thesis, 2010)The thesis consists of a “state of the art study” on different materials resistance to adhesive wear, an investigation of existing and new test method, and an experimental part to address the influence of high pressures ... -
Tribology Mechanisms in Low-Friction Hardbanding Coatings.
(Master thesis, 2013)As the shallow and easily accessible oil and gas reservoirs are becoming depleted, the oil and gas industry has turned its attention towards the deeper and more remote reservoirs. The increased drilling depth, more complex ... -
