Uncertainties in current measurements in the northern North Sea
(Journal article; Peer reviewed, 2017)A met–ocean measurement program of waves and current profiles at five locations in the northern North Sea was performed over a period of approximately 5 years. Despite quality control, the measured current speed data ... -
Unfrozen Skewed Turbulence for Wind Loading on Structures
(Peer reviewed; Journal article, 2022)The paper introduces an algorithm to generate a three-variate four-dimensional wind turbulence field suited for yawed wind dynamic load simulation. At large yaw angles, a relaxation of Taylor’s hypothesis of frozen turbulence ... -
Unlocking Household Electricity Consumption in Pakistan
(Peer reviewed; Journal article, 2021-11)In Pakistan, data for household electricity consumption are available in the form of monthly electricity bills only, and, therefore, are not helpful in establishing appliance-wise consumption. Further, it does not help in ... -
Unsteady RANS Simulations of Flow around a Twin-Box Bridge Girder Cross Section
(Journal article; Peer reviewed, 2019-07)The aerodynamic performance of bridge deck girders requires a thorough assessment and optimization in the design of long-span bridges. The present paper describes a numerical investigation of the aerodynamic characteristics ... -
Use of circular economy practices during the renovation of old buildings in developing countries
(Peer reviewed; Journal article, 2023)The construction industry is responsible for over 30% of global natural resource extraction and 25% of solid waste production, primarily due to its prevalent "take, make, dispose" economic model. Shifting toward a circular ... -
Use of digital technology to follow the consequences of a warming Arctic climate
(Peer reviewed; Journal article, 2021)The rapid warming climate is causing the Arctic ice to retreat and the permafrost to melt. These visible manifestations of the ongoing climate change are few of many environmental and societal changes that take place in ... -
Use of response forecasting in decision making for weather sensitive offshore construction work
(Peer reviewed; Journal article, 2023)Response forecasting is an emerging technology for supporting decision-making during offshore construction work. The method aims to improve the reliability and efficiency of weather-sensitive operations. This article ... -
Use of simulator training to mitigate risks in arctic shipping operations
(Peer reviewed; Journal article, 2019)Over the recent years, ship traffic in the polar areas has increased. There is reason to believe that this traffic, and especially the cruise traffic, will increase further as the ice retracts towards the poles. There is ... -
Using the Kriging Response Surface Method for the Estimation of Failure Values of Carbon-Fibre-Epoxy Subsea Composite Flowlines under the Influence of Stochastic Processes
(Peer reviewed; Journal article, 2022)This paper investigates the use of the Kriging response surface method to estimate failure values in carbon-fibre-epoxy composite flow-lines under the influence of stochastic processes. A case study of a 125 mm flow-line ... -
Utilization of Industrial By-Products/Waste to Manufacture Geopolymer Cement/Concrete
