A multi-stage optimization method for cost-optimal and nearly-zero-energy building solutions in line with the EPBD-recast 2010
(Journal article; Peer reviewed, 2013)Finding cost-optimal solutions towards nearly-zero-energy buildings (nZEBs) in accordance with European energy performance of buildings directive (EPBD-recast 2010) is a challenging task. It requires exploring a huge number ... -
A New Adaptive Cruise Control Strategy and Its Stabilization Effect on Traffic Flow
(Journal article; Peer reviewed, 2018)Connected and autonomous vehicle (CAV) technologies are likely to be gradually implemented over time. In this paper, an adaptive cruise control, named Smart Driver Model (SDM), is proposed to describe the autonomous vehicles ... -
A New Concept of Multi-Scenario, Multi-Component Animated Maps for the Visualization of Spatio-Temporal Landscape Evolution
(Journal article; Peer reviewed, 2011)In this paper, we propose a new approach to the presentation of the spatio-temporal evolution of landscape using a multi-component multi-scenario animated map system. The concept of multi-scenario map was introduced with ... -
A New Foundation Model for Integrated Analyses of Monopile-based Offshore Wind Turbines
(Journal article; Peer reviewed, 2017)Offshore wind turbines are highly dynamic and tightly coupled systems subjected to variable cyclic loads. Designing and optimizing the support structure is a complex task, where several load scenarios have to be analysed ... -
A New Level Set Numerical Wave Tank with Improved Density Interpolation for Complex Wave Hydrodynamics
(Journal article; Peer reviewed, 2016)A new three-dimensional numerical wave tank is developed for the calculation of wave propagation and wave hydrodynamics by solving the incompressible Navier–Stokes equations. The free surface is modeled with the level set ... -
A Non-normal-mode Marginal State of Convection in a Porous Box with Insulating End-Walls
(Journal article; Peer reviewed, 2019)The 4th order Darcy-Benard eigenvalue problem for the onset of thermal convection in a 3D rectangular porous box is investigated. We start from a recent 2D model for a rectangle with hand-picked boundary conditions defying ... -
A numerical study of capacity and stiffness of circular skirted foundations in clay subjected to combined static and cyclic general loading
(Journal article; Peer reviewed, 2017)Skirted foundations have been widely applied as offshore foundations for several decades. In design, the use of failure envelopes is convenient for assessing stability under combined loading. A large number of studies on ... -
A phenomenological explanation of the pressure-area relationship for the indentation of ice: Two size effects in spherical indentation experiments
(Journal article, 2015)Indentation tests provide a simple means to study the inelastic behavior of ice and other materials when loaded under a compressive stress state. Such tests provide force–time plots which are often converted to pressure–area ... -
A proposal of energy performance indicators for a reliable benchmark of swimming facilities
(Journal article; Peer reviewed, 2016)The main research question tackled in this work is which energy performance indicator should be used to benchmark energy usage in swimming facilities. After the design and administration of a survey, data from 43 Norwegian ... -
A review and comparison of floating offshore wind turbine model experiments
(Journal article; Peer reviewed, 2016)Floating off shore wind turbines provide more access to deeper water than conventional fixed bottom wind turbines, which expands the viable area for wind energy development, reduces visibility from shore, and can potentially ... -
A review of indices for assessing visual comfort with a view to their use in optimization processes to support building integrated design
(Journal article; Peer reviewed, 2015)In the last decades, several studies aimed at assessing some specified aspects of visual comfort characterizing the relationship between the human needs and the light environment, such as an available amount of light, ... -
