Performance assessment of all-air heating in an office cubicle equipped with an active supply diffuser in a cold climate
(Journal article; Peer reviewed, 2019)Low-temperature space heating systems play a prominent role in improving the indoor air quality (IAQ) and thermal comfort of energy efficient buildings in cold-climate countries such as Norway. All-air heating (AAH) systems ... -
Performance assessment of K-out-of-N safety instrumented systems subject to cascading failures
(Peer reviewed; Journal article, 2021)Safety instrumented systems often employ redundancy to enhance the ability to detect and respond to hazardous events. The use of redundancy increases the fault tolerance to single failure but remains vulnerable in case of ... -
A Performance Assessment of Polarimetric GNSS-R Sea Level Monitoring in the Presence of Sea Surface Roughness
(Peer reviewed; Journal article, 2021)Monitoring coastal sea level has gained a large socioeconomic and environmental significance. Ground-based Global Navigation Satellite System Reflectometry (GNSS-R) offers various geophysical parameters including sea surface ... -
Performance Assessment of Redundancy Strategies of Systems Subject to External Shocks
(Chapter, 2022)Engineering systems are subject to degradation due to operational conditions and usage. The systems are also subject to random external shocks that are capable of causing abrupt failures. To maintain desired system performance ... -
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 ... -
