Reliability and Validity of the Norwegian Family Sense of Coherence Scale
(Journal article; Peer reviewed, 2016)Aims and Objectives: To investigate reliability and validity of the translated Norwegian version of the Family Sense of Coherence scale. Background: The Family Sense of Coherence scale measures the global sense of coherence ... -
The Reliability and Validity of the Norwegian Version of the Quality of Life in Late-Stage Dementia Scale
(Journal article, 2015)Aim: To translate the Quality of Life in Late-Stage Dementia (QUALID) Scale into Norwegian, and to evaluate the test-retest reliability and validity of the scale. Method: QUALID was translated according to standardised ... -
Reliability assessment for final elements of SISs with time dependent failures
(Journal article, 2018)Reliability assessment for safety-instrumented systems (SISs) plays a vital role in improving the design of SISs. Traditional methods for SIS reliability assessment that assume constant failure rates are, however, not ... -
Reliability assessment for subsea HIPPS valves with partial stroke testing
(Chapter, 2017)High integrity pressure protection systems (HIPPS) have been applied in subsea applications to prevent accidents due to over-pressurization. A subsea HIPPS can be regarded as a complete functional loop consisting of sensors, ... -
Reliability assessment of a bridge structure subjected to chloride attack
(Journal article; Peer reviewed, 2018)Prediction of the service lifetime of concrete structures with respect to chloride ingress involves a number of parameters that are associated with large uncertainties. Hence, full-scale measurements are strongly in demand. ... -
RELIABILITY ASSESSMENT OF A SUBSEA HIPPS
(Master thesis, 2014)Safety instrumented systems are vital in the oil and gas industry. A SIS consists of input elements, a logic solver and final elements. A High Integrity Pressure Protection System is an example of such a system. HIPPS is ... -
Reliability assessment of digital forensic investigations in the Norwegian police
(Journal article; Peer reviewed, 2022) -
Reliability Assessment of Distribution Systems: -Including a case study on Wangdue Distribution System in Bhutan
(Master thesis, 2009)A stable and reliable electric power supply system is an inevitable pre-requisite for the technological and economic growth of any nation. Due to this, utilities must strive and ensure that the customer s reliability ... -
Reliability Assessment of Long Span Suspension Bridges Subjected to Dead Loads
(Master thesis, 2016)In the present study the influence of standardized safety factors in large and heavy structures, where the major loading arises from self-weight of the structure itself, is considered. For this purpose, a reliability ... -
Reliability assessment of safety instrumented systems operating in high demand mode
(Master thesis, 2010)Safety instrumented systems (SISs) play an important role in protecting human life, the environment, and material and financial assets. In order to achieve the expected protection function, high reliability of such systems ... -
Reliability Assessment of Safety Instrumented Systems: An Application Example For A Ballasting System: Pålitelighetsvurdering av instrumenterte sikkerhetssystemer: Med anvendelsesområde for et ballasteringssystem
(Master thesis, 2012)Ballast systems perform important safety functions on ships and floating facilities, and failure to ballast properly may lead to a major accident, involving multiple fatalities, release to environment and loss of vessel. ... -
Reliability assessment of subsea BOP control systems
(Master thesis, 2015)The subsea blowout preventer (BOP) and the BOP control system were the most important contributors to the Macondo accident in April 2010. A BOP is a large valve system used during the drilling phase; to seal, control, and ... -
Reliability assessment of subsea BOP shear ram preventers
(Master thesis, 2015)The objective of this report is to assess the reliability of blind shear rams (BSRs). The BSR's failure to seal off and secure the well in the Macondo incident proved the necessity of reevaluating the abilities of current ... -
Reliability Assessment of Subsea X-mas Tree Configurations
(Master thesis, 2015)The focus of this thesis is to provide input for choosing the optimal X-mas Tree (XT) configuration for a subsea production system. The subsea XT is used to direct, regulate, and stop the flow from a well. These functions ... -
Reliability Assessment Tool for Modern Electrical Distribution Systems – A Monte Carlo Simulation Approach
(Doctoral theses at NTNU;2023:172, Doctoral thesis, 2023)The electrical power system is under constant development, and multiple changes will occur in the upcoming years, leading to a more intelligent and active system with the integration of ICT, distributed generation, and ... -
Reliability assessments of concrete structures using non-linear finite element analyses
(Master thesis, 2017)Reliability assessment of slender concrete columns using Non-linear finite element analysis (NLFEA) is studied in this thesis. Several reliability methods in combination with NLFEA are applied and discussed to assess the ... -
Reliability assessments of railway signaling systems: A comparison and evaluation of approaches
(Master thesis, 2015)The railway signaling system is the key system to ensure the safe operation of railway traffic. It is therefore important to have a safe and reliable railway signaling system. The railway authority defines requirements ... -
