Guarneri, H. (author), Verlaan, M. (author), Slobbe, D.C. (author), Veenstra, J. (author), Zijl, F. (author), Pietrzak, J.D. (author), Snellen, M. (author), Keyzer, L.M. (author), Afrasteh, Y. (author), Klees, R. (author)Both empirical and assimilative global ocean tidal models are significantly more accurate in the deep ocean than in shelf and coastal waters. In this study, we answered whether this is due to the quality of the models used to reduce tide and surge or the general approach to treat tide and surge as two separate components of the water level...journal article 2023

Buskes, V. F. (author), Kaczmarek, M.B. (author), Veenstra, J. C. (author), Coulais, C. (author), Hassan HosseinNia, S. (author)Metamaterials are artificial structures with properties that are rare or non-existent in nature. These properties are created by the geometry and interconnection of the metamaterial unit cells. In active metamaterials, sensors and actuators are embedded in each unit cell to achieve greater design freedom and tunability of properties after the...conference paper 2023

(author), Theelen, Mirjam (author)Nonequal current generation in the cells of a photovoltaic module, e.g., due to partial shading, leads to operation in reverse bias. This quickly causes a significant efficiency loss in perovskite solar cells. We report a more quantitative investigation of the reverse bias degradation. Various small reverse biases (negative voltages) were...journal article 2023

Wang, X. (author), Verlaan, M. (author), Veenstra, Jelmer (author), Lin, H.X. (author)Global tide and surge models play a major role in forecasting coastal flooding due to extreme events or climate change. The model performance is strongly affected by parameters such as bathymetry and bottom friction. In this study, we propose a method that estimates bathymetry globally and the bottom friction coefficient in shallow waters for a...journal article 2022

Veenstra, C.R.A. (author), Noteboom, C. (author), Oikonomopoulou, F. (author), Overend, M. (author)This research revolves around the design, fabrication and testing of tubular glass columns, with particular focus on their redundancy and fire-safety mechanisms; moreover, addressing aspects such as: the column shape; cleaning and maintenance; end connections; geometric tolerances in the glass and demountability. Two alternative circular hollow ...conference paper 2022

Heijmann, Frank (author), Tan, Y. (author), Rukanova, B.D. (author), Veenstra, Albert (author)The World Customs Organization (WCO) Framework of Standards to Secure and Facilitate Global Trade (SAFE) introduced concepts of supply chain supervision and authorised operator schemes. While it has been implemented in many countries, supply chain supervision still requires further exploration and development. In this article we present a vision...journal article 2020

Kislaya, A. (author), Deka, Antaran (author), Veenstra, Peter (author), Tam, D.S.W. (author), Westerweel, J. (author)Abstract: In microscopic particle image velocimetry (micro-PIV), correlation averaging over multiple frames is often required, leading to a loss in temporal resolution, therefore limiting the measurement accuracy for unsteady flows. Here, we present a new PIV method suitable to study steady and unsteady laminar flows between parallel plates ...journal article 2020

Kislaya, A. (author), Deka, Antaran (author), Veenstra, Peter (author), Tam, D.S.W. (author), Westerweel, J. (author)In micro-PIV, reaching the optimum image density has always been difficult due to high displacement gradient, coagulation of particles at the inlet and due to particles adhering to the surface to name a few. The most widely used method is to take ensemble correlation average of multiple PIV images to extract the velocity field. However, this...conference paper 2018

(author)The perovskite solar cell is considered a promising candidate as the top cell for high-efficiency tandem devices with crystalline silicon (c-Si) bottom cells, contributing to the cost reduction of photovoltaic energy. In this contribution, a simulation method, involving optical and electrical modelling, is established to calculate the...journal article 2016

(author)The organic photovoltaics field is maturing and reaching a technology readiness level where the focus is on developing large scale fabrication methods. In this light, fully inkjet printed organic solar cells were demonstrated. Inkjet printing allows direct patterning of all the layers, including the electrodes, offering full freedom of design...journal article 2015

Veenstra, A.W. (author), Hulstijn, J. (author), Christiaanse, R.M.J. (author), Tan, Y. (author)An integrated data pipeline has been proposed to meet requirements for visibility, supervision and control in global supply chains. How can data integration be used for risk assessment, monitoring and control in global supply chains? We argue that concepts from model-based auditing can be used to model the ‘ideal’ flow of money and goods, and by...conference paper 2013

Pourakbar, M. (author), Zuidwijk, R.A. (author), Veenstra, A. (author), Lucassen, I. (author)This paper aims at studying the coordination of governmental actors, such as customs, and supply chain partners in order to mitigate risks. To do so the concepts of supply chain visibility and data pipeline are briefly revisited.
