Pauser i tidligfase i norske byggeprosjekter - Årsaker og konsekvesner
(Master thesis, 2017)Gjennom analyse av tidsdata gjennom forskningsprosjektet SpeedUp er det observert at det oppstår pauser i tidligfasen i større norske byggeprosjekter. Målet med denne studien er å se på årsakene som forårsaker disse pausene ... -
Pd-Functionalized ZnO:Eu Columnar Films for Room-Temperature Hydrogen Gas Sensing: A Combined Experimental and Computational Approach
(Peer reviewed; Journal article, 2020)Reducing the operating temperature to room temperature is a serious obstacle on long-life sensitivity with long-term stability performances of gas sensors based on semiconducting oxides, and this should be overcome by new ... -
Perception by Palpation: Development and Testing of a Haptic Ferrogranular Jamming Surface
(Master thesis, 2021)Denne masteroppgaven beskriver konseptutviklingsprosessen av et haptisk brukergrensesnitt ment for trening på palpasjon. Utviklingsprosessen involverer utforskning, design, bygging og testing av konseptet. Inspirasjonen ... -
Perception by Palpation: Development and Testing of a Haptic Ferrogranular Jamming Surface
(Peer reviewed; Journal article, 2021)Tactile hands-only training is particularly important for medical palpation. Generally, equipment for palpation training is expensive, static, or provides too few study cases to practice on. We have therefore developed a ... -
Performance analysis for subsea blind shear ram preventers subject to testing strategies
(Journal article; Peer reviewed, 2018)In a subsea blowout preventer system, a subsea blind shear ram preventer (BSRP) plays as a crucial safety barrier by cutting off the drill pipe and sealing the wellhead to prevent serious accidents. Testing and repairs of ... -
Performance analysis of redundant safety-instrumented systems subject to degradation and external demands
(Journal article; Peer reviewed, 2019)Safety-instrumented systems (SISs) play a vital role in preventing hazardous events in the offshore facilities. Many of existing performance analysis of SISs are based on the constant failure rate assumption, which is ... -
Performance analysis of safety barriers against cascading failures in a battery pack
(Peer reviewed; Journal article, 2022)Lithium-ion batteries have been widely employed as the principal power source in electric vehicles and other storage systems. However, some critical issues in a battery pack still exist, such as thermal failures on initial ... -
Performance analysis of safety instrumented systems against cascading failure during prolonged demand
(Peer reviewed; Journal article, 2021)Cascading failures may occur in many technical systems where the failure of one component triggers successive events. Safety barriers like safety instrumented systems are installed in many industries to prevent failures ... -
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 ... -
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 Management for Parametric Building Design Generated by a Genetic Algorithm
(Peer reviewed; Journal article, 2024)The paper analyzes the results of applying a genetic algorithm to generate building designs. The genetic algorithm developed by the authors uses shadow length as fitness function value to examine the impact on the building ... -
PERFORMANCE MANAGEMENT USING BUSINESS INTELLIGENCE
(Master thesis, 2011)The purpose of this thesis is to develop a solution for how an effective lean performance measurement system can be developed and how the system can be supported by business intelligence. The motivation behind this exercise ... -
Performance Measurement using Deep Digital Maintenance (DDM) Concept: A Technique for Measuring "Hidden Factory"
(Master thesis, 2022)På grunn av måten konkurranse driver både kostnader og innovasjon på i dag, leter produksjonsselskaper etter alle mulige måter å minimere kostnader, redusere risiko forbundet med fysiske eiendeler, forbedre eiendelens ... -
