Assessment of dynamic barriers in oil/gas well operations: Vurdering av dynamiske barrierer i olje/gass brønner
(Master thesis, 2014)Well integrity is an important topic in oil and gas well operations. The intention is to control the reservoir fluids and well pressures, by technical, operational and organizational barriers. Inadequate barriers can lead ... -
Assessment of early warning signs in hospital projects’ front-end phase
(Peer reviewed; Journal article, 2022)Purpose The front-end phase plays an important role in achieving project success, and establishment of performance measurement systems considering project challenges or pitfalls is a way of keeping track of this phase. ... -
Assessment of expected production of a deep-sea mining system: An integrated model-based systems engineering and discrete event simulation approach
(Peer reviewed; Journal article, 2023)In this paper, model-based systems engineering (MBSE) and discrete event simulation (DES) are combined to assess the performance of an offshore production system at an early stage. Various systems engineering tools are ... -
Assessment of fruit ripening through electrical impedance spectrometry.
(Bachelor thesis, 2020)In this thesis, some of the different parameters that can determine fruit ripening have been measured and analyzed through non-destructive techniques by following the ripening process of three different kinds of fruits: ... -
Assessment of mixed mode fatigue crack growth under biaxial loading using an iterative technique
(Peer reviewed; Journal article, 2020)Crack growth is investigated numerically in a cruciform specimen with an inclined center crack subjected to biaxial fatigue loading. The mixed-mode fatigue crack growth was examined using a parametric study both on the ... -
Assessment of Order Picking Technologies in Picker-to-parts Order Picking Systems: An MCDM Approach
(Master thesis, 2022)This thesis evaluates the available order picking technologies and their level of automation based on performance criteria in picker-to-parts order picking systems. To evaluate these technologies a group MCDM approach was ... -
Assessment of Prior Use Requirements of IEC-61511
(Master thesis, 2023)Funksjonell sikkerhet er av største betydning i bransjer der svikt i sikkerhetssystemer kan føre til katastrofale konsekvenser. International Electrotechnical Commission (IEC) introduserte IEC 61511-standarden for å gi ... -
Assessment of safety barriers for the prevention of cascading events in oil and gas offshore installations operating in harsh environment
(Journal article, 2018)Fire in the topside production area of offshore Oil and Gas (O&G) platforms has the potential to trigger cascading events and may lead to catastrophic consequences for operators, environment and asset. Safety barriers, ... -
Assessment of Structural Integrity and Potential Improvements of Micro Hydropower Turbine
(Master thesis, 2013)A comparative study of two different hydro power turbine designs, madeby Remote Hydrolight (RHL) was conducted. The shaft of the first designhas suffered from fatigue failures and a bushing was introduced to solvethe ... -
Assessment of tensile and fatigue behavior of PEEK specimens in a physiologically relevant environment
(Journal article; Peer reviewed, 2019)In the last decades the necessity of implant devices is continuously increasing. The researchers have thus focused their attentions on the development of new biocompatible materials, in particular polymers. Among them, ... -
Assessment of the Mechanical Integrity of a 2 mm AA6060-T6 Butt Weld Produced Using the Hybrid Metal Extrusion & Bonding (HYB) Process – Part I: Bend Test Results
(Journal article; Peer reviewed, 2019)The present investigation is concerned with butt welding of 2 mm thin AA6060-T6 profiles at room temperature (RT), using the HYB process and AA6082-T4 as filler material. In the as-welded condition, the 1000 mm long butt ... -
