Performance Assessment of Safety-instrumented Systems Subject to Cascading Failures in High-demand Mode
(Chapter, 2019)Safety-instrumented systems are designed to act upon hazardous events and reinforce safety. IEC 61508 specifies two possible reliability measures of safety-instrumented systems: the average probability of failure on demand ... -
Performance Assessment of Songo Songo Gas Field: Dynamic Approach
(Master thesis, 2014)The primary purpose of this work is to evaluate the dynamic performance of the Songo Songo gas field through tuning the model to characterize reservoir performance. The work is dedicated on evaluation of aquifer activity ... -
Performance assessment of the built environment in healthcare facilities
(Peer reviewed; Journal article, 2021)Purpose – This study presents findings of post-occupancy evaluation (POE), through a performance assessment, on a polyclinic, as a health-care facility, in Saudi Arabia. Design/methodology/approach – Review of the literature ... -
Performance assessment of the energy system onboard an LNG FPSO
(Master thesis, 2011)LNG power and heat systems, the balance of demand is dependent of the feed gas and on the location of the production vessel. Further, the power and heat balance is dependent on the gas processing efficiencies and the air ... -
Performance assessment of the semi-distributed hydrological model HYPE for central Norway
(Master thesis, 2017)Norway s water authorities need a comprehensive tool to generate hydrological infor- mation for all water bodies to implement the European water framework directive. The precipitation-runoff model HYPE was developed by the ... -
Performance Assessment of Transient Signal Detection Methods and Superiority of Energy Criterion (EC) Method
(Peer reviewed; Journal article, 2020)Radio frequency fingerprinting (RFF) based on RF transients is one of the most effective techniques for improving wireless security. For an efficient RFF development, RF transients need to be accurately detected. However, ... -
Performance based modelling of long-term deterioration to support rehabilitation and investment decisions in drinking water distribution systems
(Journal article; Peer reviewed, 2017)Managing the urban drinking water system in the long term in order to maintain system performance can be challenging due to the difficulty of modelling future deterioration of the networks. This paper establishes a methodology ... -
Performance Bounds for Tracking Multiple Objects using a Single UAV
(Chapter, 2017)In this paper we calculate probabilistic estimates for the size of an area a single unmanned aerial vehicle (UAV) can expect to monitor when tracking multiple objects. The objects are assumed to move according to a linear ... -

Performance Calculations for a Model Turbine
(Master thesis, 2009)En modell av en vindturbin er studert numerisk og eksperimentelt. Dette er gjort for å verifisere at modellen fungerer i henhold til de beregninger som ble lagt til grunn i designprosessen. Vindturbinen har en diameter på ... -
The performance change of aluminum electrolysis in standard cryolite electrolyte with cathodic current density
(Master thesis, 2017)A series of experiments were performed to verify the effect of current density in current efficiency of aluminum electrolysis in molten salts. To avoid interference of other parameters, a special designed laboratory cell ... -
Performance Characteristics of the NREL S826 Airfoil - An assessment of Re-Independency and effect of inflow turbulence
(Master thesis, 2015)Lift- and drag measurements on an NREL S826 airfoil were performed experimentally in NTNU s low-speed wind tunnel. Reynolds number effects were investigated in the range Re = 0.7 × 105 6.0 × 105 at angles of attack ... -
Performance Characterization of Warm-Mix Asphalt Containing High Reclaimed-Asphalt Pavement with Bio-Oil Rejuvenator
(Peer reviewed; Journal article, 2020)Warm-mix asphalt (WMA) technology and recycling of asphalt pavement, i.e., reclaimed asphalt pavement (RAP), have been becoming more popular in recent years due to their economic and environmental benefits. Similarly, ... -
