Safari, Vahid (author), Kamkari, Babak (author), Hewitt, Neil (author), Hooman, K. (author)The low thermal conductivity of phase change materials (PCMs) has limited their widespread use in practical applications. In the present study, different fin structures, namely, rectangular, perforated, and pin were examined to analyze the thermal performance of the melting process in rectangular latent heat storage tanks. Experiments were...journal article 2024

MAHAJAN, SAURABH (author)Structural joints influence the design strength, material requirement of a structure. Structural joints experience damping dissipation due to friction damping or hysteresis damping. Damping is often used for reducing the vibrations in a structure. However, large amount of energy dissipation leads to deterioration of the material used for...master thesis 2023

Spijksma, Cedric (author)Architects and urban planners still rely on physical models in the design process, particularly for urban contexts. However, developing such models can be time-consuming and resource-intensive, despite the abundance of digital information available. This study investigates the feasibility of using pin-type models, specifically in the concept and...master thesis 2023

Conde, Jorge (author), da Silva, Luis S. (author), Tankova, T. (author), Simões, Rui (author), Abecasis, Tiago (author)The design of pin connections between steel members has been established for many years in design codes. However, recently, in the scope of the revision of Eurocode 3, Part 1–8 (EN 1993–1-8), questions were raised concerning the safety of the corresponding design verifications. This paper identifies two main aspects that require revision,...journal article 2023

Liu, Y. (author), Pamososuryo, A.K. (author), Mulders, S.P. (author), Ferrari, Riccardo M.G. (author), van Wingerden, J.W. (author)The estimation of the rotor effective wind speed is used in modern wind turbines to provide advanced power and load control capabilities. However, with the ever increasing rotor sizes, the wind field over the rotor surface shows a higher degree of spatial variation. A single effective wind speed estimation therefore limits the attainable...journal article 2022

Vuillot, C. (author), Breuckmann, Nikolas P. (author)We introduce quantum pin codes: a class of quantum CSS codes. Quantum pin codes are a generalization of quantum color codes and Reed-Muller codes and share a lot of their structure and properties. Pin codes have gauge operators, an unfolding procedure and their stabilizers form so-called $\ell $ -orthogonal spaces meaning that the joint...journal article 2022

Liu, Yue (author), Rens, E.G. (author), Edelstein-Keshet, Leah (author)The polarization and motility of eukaryotic cells depends on assembly and contraction of the actin cytoskeleton and its regulation by proteins called GTPases. The activity of GTPases causes assembly of filamentous actin (by GTPases Cdc42, Rac), resulting in protrusion of the cell edge. Mathematical models for GTPase dynamics address the...journal article 2021

Fernandez-Toledano, Juan-Carlos (author), Rigaut, Clement (author), Mastrangeli, Massimo (author), de Coninck, Joel (author)Hypothesis The contact line pinning that appears in a flow coating process over substrates patterned with chemical or physical heterogeneities has been recently applied to deposit micro- and nanoparticles with great precision. However, the mechanism underlying pinning of a receding contact line at the nanoscale is not yet well understood. In the...journal article 2020

Chhabra, Arjun (author)Suzlon's wind turbine blades are connected to the pitch bearing and hence the hub using a T-Bolt (Ikea) connection. The merits of this bolted connection and the experience in its usage has led to its continuous use in the wind industry. Engineers at Suzlon believe that this connection can be optimized by improving the net-tension strength and...master thesis 2019

PAPAIOANNOU, Giannis (author)Sustainable railway systems with less disturbance are highly desired. Insulated rail joint (IRJ) is one important structural component in a railway track. IRJs serve the railway system with two crucial functions: dividing track into sections for signal control and enable the detection of broken rails. An IRJ generally consists of two fishplates,...master thesis 2018
