Risk-Based Inspection (RBI) has been utilized in the offshore industry, but it is rarely applied for inland navigation lock gates. This research presents a framework where Dynamic Bayesian network (DBN) is used for risk-based inspection planning of a miter gate considering inspection data. The study incorporates two sets of heuristic decision rules...

Radiation budget instruments scan the earth, creating radiation maps that are interpreted as effective temperature. Then in a sense, these instruments continuously monitor the earth’s radiation budget. Since the measured signals are relatively weak, accurate mathematical modeling is critical to the design process. A mathematical model of the therma...
Reliability assessment of existing offshore wind turbine (OWT) support structures taking advantage of historical data from inspection and monitoring is crucial for the optimisation of maintenance and life extension. In this thesis, the crack inspection data and the monitoring data are separately considered for updating failure probability of welded...

Fiscal and monetary policies are two pillars of macroeconomic policy, for both accelerating growth and ensuring stability. Their relative roles and the nature of interface have been of great interest to both academics and policy makers. This paper presents a practitioner’s perspective of how the interface evolved in India. The pre-reform status of ...
Den ökade mängden realtidsdata som bland annat IoT-utvecklingen för med sig gör business intelligence (BI) i realtid mer relevant än någonsin. Då många BI-projekt tenderar till att misslyckas är förståelse av kritiska framgångsfaktorer vitalt. Denna studie syftar till att undersöka vilka skillnader i kritiska framgångsfaktorer som utmärker implemen...

During their operational lifetime, the static process equipment (including piping, pipelines and topside static equipment) that constitute an offshore oil and gas production installation are subjected to a number of degrading mechanisms, like corrosion and erosion. These degradation mechanisms can significantly reduce the integrity of equipment the...

Satellite instruments operating in the reflective solar wavelength region require accurate and precise determination of the Bidirectional Reflectance Distribution Functions (BRDFs) of the laboratory and flight diffusers used in their pre-flight and on-orbit calibrations. This paper advances that initial work and presents a comparison of spectral Bi...
For offshore wind turbines, the support structure contributes with a significant part to the Levelized Cost Of Energy (LCOE). LCOE is the total cost to build and operate a whole offshore wind turbine structure over its lifetime divided by the total energy output of the wind turbine over that lifetime. That total expected cost of operation & mainten...
The aim of this paper is to present the development of a standards-based software aPi- RP-580/581, which is running a series of calculations in order to provide greater reliability to Management Structural Integrity of Campo Escuela, which is currently under responsibility of the Metallurgical Engineering School of Industrial University of Santande...

Due to the shift from software-as-a-product to software-as-a-service, software components that were developed to run in a single address space must increasingly be accessed remotely across the network. Distribution middleware is frequently used to facilitate this transition. Yet a range of middleware platforms exist, and there are few existing guid...
