van der Lingen, Annick (author)This study aims to explore the impact of employee separation as a result of hybrid working on the organisational commitment of ORGANISATION X’s workforce. The findings of this research aim to offer valuable insights to ORGANISATION X's understanding on how the alternating remote and in-office work setup may influence the commitment levels of...master thesis 2023

Sławek, Andrzej (author), Jajko, Gabriela (author), Ogorzały, Karolina (author), Dubbeldam, David (author), Vlugt, T.J.H. (author), Makowski, Wacław (author)In this work, adsorption properties of the UiO-66 metal–organic framework were investigated, with particular emphasis on the influence of structural defects. A series of UiO-66 samples were synthesized and characterized using a wide range of experimental techniques. Type I adsorption isotherms for low-temperature adsorption of N<sub>2</sub>...journal article 2022

Stuber, V.L. (author), Kotsonis, M. (author), van der Zwaag, S. (author)Two piezoelectric series bimorph sensors were embedded below the skin of a NACA 0012 symmetrical airfoil to detect the local state of the boundary layer during wind tunnel testing. Small vanes piercing the airfoil skin were glued onto the bimorphs providing a mechanical coupling to the local mechanical force fluctuations imparted by the local...journal article 2022

de Jong, bart (author)Growing populations, high-technology applications and the energy transition raise the demand for rare earth elements. As a secure supply in the future is all but certain, opportunities arise for deep-sea mining. Polymetallic nodules<br/>that are located on the vast, sediment-covered ocean floors, are one of the more promising deep-sea mineral...master thesis 2021

Mohan, Keerthana (author)Separation of particles from suspensions has been an integral part of many industrial, chemical and biological processes. Traditional methods such as sieving, flocculation, centrifugation etc. have many demerits. This has lead to an interest in unconventional separation methods that use physical properties of the particles. Acoustophoresis is...master thesis 2020

Ishiyama, Tomohide (author), Ali, Mohammed (author), Blacquière, G. (author), Nakayama, S. (author)We introduce a blended-acquisition method: temporally signatured and/or modulated and spatially dispersed source array, namely S-/M-DSA. The former S-DSA has much less constraints in the encoding with operational flexibility, allowing non-uniform sampling and non-patterned shooting both in the space and time dimension. The latter M-DSA allows...conference paper 2019

Schoenmaker, Lars (author)In this thesis diffuser performance will be simulated with computational fluid dynamics, which will be done with the program Ansys Fluent. The expanding geometry creates an adverse pressure gradient and under certain conditions there will also be separation.<br/><br/>At first a relative simple simulation will be done of a one-directional...master thesis 2017

Oudshoorn, Tijmen (author)This thesis consist of the graduation project executed in cooperation with the municipality of the Hague, at design studio DIDID in the Hague. The beaches of the Hague are cleaned by so called beach cleaners. Beach cleaners are large tractor pulled screening machines that effectively screen/rake garbage from the beach. There is however a problem...master thesis 2017

Braymand, Sandrine (author), Roux, Sébastien (author), Fares, Hanaa (author), Feugeas, Françoise (author)Construction and demolition waste stream has generated news materials that may be reintroduced into new concrete, e.g. as recycled aggregates. The specific feature of recycled concrete aggregates (RCA) is the presence of hardened mortars influencing their behaviour. This study aims to distinguish processes that allow the complete separation and...conference paper 2017

Janssen, B.P.M. (author)In the goal of creating a safer environment for bicyclists and pedestrians, there is an on-going debate about the usefulness of kerbs as a separation between these two modes. Right angled kerb types separate well but are not forgiving. Sloped and levelled kerb types are more forgiving, but the extent to which they separate is unknown. A video...master thesis 2016

(author)The objective of the present study was to examine the relative timing of pelvis and thorax rotations in achieving high throwing velocities in baseball pitching. During the preseason, a kinematic analysis was performed on eight pitchers. Peak angular velocities of the pelvis and thorax were determined and separation, defined as the time between...conference paper 2016

Van Campen, L.J.A.M. (author)Separation of oil and water is an essential step in the treatment of the production streams from fossil oil wells. Settling by gravity is a robust though voluminous process and therewith expensive method at remote locations, leading to a need for smaller separation equipment. In this thesis, we describe the research performed on the development...doctoral thesis 2014

Grobbe, N. (author), Van der Neut, J. (author), Almagro Vidal, C. (author)We present a new approach to apply wavefield decomposition, illustrated for an energy flux-normalized elastodynamic case. We start by considering a situation where two horizontal boreholes are closely separated from each other. By recording only the particle velocities at both depth levels (for example with conventional 3-component geophones)...journal article 2013

Van der Neut, J. (author), Bakulin, A. (author), Aramco, S. (author), Alexandrov, D. (author)We present a novel inversion scheme for decomposing upgoing and downgoing wavefields from vertical particle velocity recordings in downhole arrays at multiple depth levels. Our method requires no knowledge of the subsurface medium parameters as the required operators are obtained directly from the data by direct-wave interferometry. As we...journal article 2013

Doulgeris, P. (author)The recording and storage capacity of modern seismic acquisition systems is continuously growing, enabling denser sampling and the acquisition of better-quality data. One big hurdle is survey time, since the duration of a survey is directly proportional to the number of sources fired. The proposed way forward is to deploy nearly simultaneous...doctoral thesis 2013

Li, W.L. (author)In the psychiatry, isolation cells are used to lock up patients, when they become emotionally instable, behave aggressively and become a danger towards their selves or his environment. The isolation cell is a low stimulus and high safety environment. This means simply put that the patient has no control in the room. He is dependent on the staff...master thesis 2012

Van der Tempel, W.M. (author)Eutectic Freeze Crystallization is a new technology to separate salt and water from a process stream. A process stream is cooled to the eutectic temperature where both ice and salt crystallize, the solids can then be separated by their density difference. Eutectic Freeze Crystallization has the potential to be much more efficient than current...master thesis 2012

Oudshoorn, A. (author)Product recovery is crucial for fermentative butanol production. Bio-based fermentative butanol production systems benefit from answering the question to what extent, and in which form, integration between fermentation and product recovery should be applied. The product recovery is applied in order to minimize the impact of butanol inhibiting...doctoral thesis 2012

Doulgeris, P. (author), Mahdad, A. (author), Blacquière Gerrit, G. (author)n conventional marine acquisition surveys the time intervals between the firing of successive sources are large enough to avoid interference in time. To obtain an efficient survey, the spatial source sampling is therefore often (too) large. How- ever, much attention has been drawn recently to blended ac- quisition designs, where sources are shot...conference paper 2011
