(author), Wang, Wenshou (author), Li, Zhenming (author)Recycling aluminosilicate-based solid wastes is imperative to realize the sustainable development of constructions. By using alkali activation technology, aluminosilicate-based solid wastes, such as furnace slag, fly ash, red mud, and most of the bio-ashes, can be turned into alternative binder materials to Portland cement to reduce the carbon...review 2024

Slot, R.E. (author), Geldof, H.J. (author)The DUST (Delft University Settling Tube) is a settling tube system intended to analyse particle size (settling velocity) of sand ranging from 0.06 mm to 2 mm, with the sample mass varying from 0.5 g to 20 g. The main parts of the system are (see fig. 1): a. the sample introduction device (venetian blind with rotating lamellae) b. the settling...report 1979

De Graaff, J. (author), Slot, R.E. (author)De laatste tijd wordt er veel onderzoek gedaan aan cohesief sediment. Het speelt een belangrijke rol bij het ondieper worden van havens en waterwegen, en bij andere soortgelijke problemen. Om cohesief sedimenttransport te kunnen voorspellen zijn gegevens nodig over de verdelingen van de groottes en de bezinksnelheden. Er bestaan veel methoden om...report 1994

Apostolou, G. (author), Reinders, A.H.M.E. (author), Verwaal, M. (author)This article presents a simple comparative model which has been developed for the estimation of the performance of photovoltaic (PV) products' cells in indoor environments. The model predicts the performance of PV solar cells, as a function of the distance from a spectrum of artificial (fluorescent light, halogen light, and light-emitting diodes...journal article 2016

Wegen, G. Van der (author), Polder, R.B. (author), Breugel, K. Van (author)Nowadays major structures require a service life of 100 years or even more. CUR committee VC81 has developed a guideline for service life design based on initiation of corrosion due to chloride penetration for exposure classes XD or XS. A semi-probabilistic simplification of the DuraCrete methodology is introduced with a probability of failure...journal article 2012

Cohen, I. (author), Brinkman, W.P. (author), Neerincx, M.A. (author)Professionals working in risky or emergency situations have to make very accurate decisions, while the quality of the decisions might be affected by the stress that these situations bring about. Integrating task feedback and biofeedback into computer-based training environments could improve trainees’ stress-coping behaviour. This paper presents...journal article 2015

Bazley, C. (author), Nugent, R. (author), Vink, P. (author)A review of literature on comfort and discomfort indicates an increase in physical discomfort during the workday. In this paper, three different types of occupations were studied to identify whether a similar discomfort pattern exists in these occupations while participants perform work throughout the work day and workweek. Results are that...journal article 2015

Khan, I.A. (author), Brinkman, W.P. (author), Hierons, R.M. (author)There is much research that shows people’s mood can affect their activities. This paper argues that this also applies to programmers, especially their debugging. Literature-based framework is presented linking programming with various cognitive activities as well as linking cognitive activities with moods. Further, the effect of mood on...journal article 2010

Rahimi, Serveh (author), Shooshtari, M. (author)Here we investigated a novel layer-based optimization technique to improve the performance of a CZTSe solar cell. By using this technique, the optical behavior and electrical properties of the proposed solar cell improved significantly as a result of the changes in the layer specifications and the layer materials. The structure of the cell...journal article 2022

van der Graaff, Erik (author), Hoozemans, Marco J.M. (author), Nijhoff, Martijn (author), Davidson, Michael (author), Hoezen, Merel (author), Veeger, H.E.J. (author)The objective of the present study was to examine the magnitude and timing of peak pelvis and thorax rotations in achieving high throwing velocities in pitching fastballs. During the preseason (Test 1 or T1) and four months later (Test 2 or T2), kinematic analysis was performed on eight elite youth pitchers throwing fastballs. Peak rotation...journal article 2018

(author)The principal aim of the work presented here is to investigate and demonstrate that a forward tilted rowing blade would result in a more efficient and effective motion of the blade through the water that would result in a higher boat speed when an equal input power is provided. A 1:5 scaled rowing boat is used to determine the performance of...journal article 2023

(author)Micro wind turbines can be structurally integrated on top of the solid base of noise barriers near highways. A number of performance factors were assessed with holistic experiments in wind tunnel and in the field. The wind turbines underperformed when exposed in yawed flow conditions. The theoretical cosθ theories for yaw misalignment did not...journal article 2021

de Souza Amorim, L.E. (author), Steindorfer, M.J. (author), Visser, Eelco (author)Context Context-free grammars are widely used for language prototyping and implementation. They allow formalizing the syntax of domain-specific or general-purpose programming languages concisely and declaratively. However, the natural and concise way of writing a context-free grammar is often ambiguous. Therefore, grammar formalisms support...journal article 2018

van der Werf, Job (author), Kapelan, Z. (author), Langeveld, J.G. (author)To evaluate the performance of Real Time Control (RTC) of urban drainage systems (UDS) a comparison is made with the pre-RTC situation, making the RTC performance dependent on the functioning of the UDS prior to implementation. To standardise things, a generalised baseline is formulated here as the operation with optimal static settings of the...journal article 2021
