Douma, Laurens Jan (author)The replacement of conventional generation units with variable renewable energy sources could have a negative impact on the balance of supply and demand of electricity. Moreover, since the variable renewable energy sources are inverter based and therefore decoupled from the grid, the overall grid inertia will decrease. To solve this problem, the...master thesis 2023

Ourabi, Hamza (author)The presence of particles in a flow can change the flow behaviour in an unpredictable manner, that leads us to multiphase flow. Multiphase flows are present in nature and in everyday life around us. The most common example of a multiphase flow, that one can think of, is the treatment of drinking water using liquid-solid fluidization in softening...master thesis 2023

Nguyen, Hoang (author)If people repeat choices in daily travel behaviour under stable conditions, over time this can form habitual travel behaviour and lead to inertia. If travellers face a new metro line, to what extent does their habitual travel behaviour affect their willingness to use this new transport alternative. This study investigate the inertia effects in a...master thesis 2023

Fu, X. (author), Qian, QK (author), Liu, Guiwen (author), Zhuang, Taozhi (author), Visscher, H.J. (author), Huang, R. (author)Neighborhood regeneration has become essential component of environmental improvement, and promoting resident participation is a key aspect of effective environmental management. However, in China, the legacy of the former housing allocation system and specific cultural contexts have led to residents' psychological inertia towards...journal article 2023

Angelides, S. C. (author), Talbot, J. P. (author), Overend, M. (author)The applications of architectural and automotive laminated glass continue to grow. This is largely due to the enhanced safety in extreme events, such as blast. However, the complex interaction between the glass fragments and the polymer interlayer after glass fracture is still only partially understood, with existing analysis methods adopting...journal article 2023

Tenpierik, M.J. (author), Lachi, Mohammed (author), Bliard, Christophe (author), Polidori, Guillaume (author), Maalouf, Chadi (author)Due to environmental concerns, bio-based materials are being increasingly investigated and used in buildings. In general, the density of these materials, and thus their thermal inertia, is low. Thermal inertia can be beneficial for reducing the energy use of buildings by damping indoor temperature fluctuations or by reducing and delaying...journal article 2023

Kamstra, Haye (author)Inertial measurement units (IMUs) offer the possibility to capture the lower body kinematics of players of outdoor team sports. However, various sources of error are present when using IMUs: the definition of the body frames, the soft tissue artefact (STA) and the orientation filter. Methods to minimize these errors are currently being used...master thesis 2022

Bellizio, Federica (author), Bugaje, Al Amin B. (author), Cremer, Jochen (author), Strbac, Goran (author)Machine Learning (ML) for real-time Dynamic Security Assessment (DSA) promises a probabilistic approach to secure lower safety margins and costs. However, future systems with a high share of renewables have low inertia and converter-interfaced devices resulting in faster dynamics. Past research on ML-based DSA used high inertia systems to...journal article 2022

Guo, Feng (author), Cheng, Gang (author), Pang, Y. (author)Aiming at a 5-DOF hybrid optical mirror polishing robot, the explicit dynamic model considering the joint friction is established and the inertia coupling distribution is studied. Firstly, the kinematics of the manipulator is solved based on closed-loop vector method, and the dynamic model is established with Newton-Euler method based on the...journal article 2022

Klifman, Boyan (author)Existing wind load simulators such as wind tunnels and fans have multiple disadvantages, especially when used in a scaled-down environment. This paper proposes to simulate wind loads by using an admittance-controlled industrial robot arm rigidly attached to a research object. Admittance control should make it possible to simulate wind loads and...master thesis 2021
