Chadwell, Alix (author), Chinn, Natalie (author), Kenney, Laurence (author), Karthaus, Zoë J. (author), Mos, Daniek (author), Smit, G. (author)The Delft Self-Grasping Hand is an adjustable passive prosthesis operated using the concept of tenodesis (where opening and closing of the hand is mechanically linked to the flexion and extension of the wrist). As a purely mechanical device that does not require harnessing, the Self-Grasping Hand offers a promising alternative to current...journal article 2021

Culmone, C. (author), Lussenburg, K.M. (author), Alkemade, J.P.E. (author), Smit, G. (author), Sakes, A. (author), Breedveld, P. (author)In the field of medical instruments, additive manufacturing allows for a drastic reduction in the number of components while improving the functionalities of the final design. In addition, modifications for users’ needs or specific procedures become possible by enabling the production of single customized items. In this work, we present the...journal article 2021

Creating 3d indoor first responder situation awareness in real-time through a head-mounted ar deviceSmit, Bart Peter (author), Voûte, R.L. (author), Verbree, E. (author)Emergency operations are a key example for the need of digital twins in the way it is complex, urgent and uncertain. First, the process is complex, as many organizations are involved. Second, it is urgent, as most damage is done in the first moments of an emergency. Third, it is uncertain, as situational conditions tend to change quickly. For...journal article 2021

Bodlaender, Hans L. (author), van Dobben de Bruyn, J. (author), Gijswijt, Dion (author), Smit, Harry (author)In this paper, we give a constructive proof of the fact that the treewidth of a graph is at most its divisorial gonality. The proof gives a polynomial time algorithm to construct a tree decomposition of width at most k, when an effective divisor of degree k that reaches all vertices is given. We also give a similar result for two related...journal article 2021

Ali, A. (author), Dodou, D. (author), Smit, G. (author), Rink, Ruben (author), Breedveld, P. (author)Positioning and stabilizing a catheter at the required location inside a vessel or the heart is a complicated task in interventional cardiology. In this review we provide a structured classification of catheter stabilization mechanisms to systematically assess their challenges during cardiac interventions. Commercially available, patented,...review 2021

Dittli, Jan (author), Hofmann, Urs A.T. (author), Bützer, Tobias (author), Smit, G. (author), Lambercy, Olivier (author), Gassert, Roger (author)Wearable robots assist individuals with sensorimotor impairment in daily life, or support industrial workers in physically demanding tasks. In such scenarios, low mass and compact design are crucial factors for device acceptance. Remote actuation systems (RAS) have emerged as a popular approach in wearable robots to reduce perceived weight...journal article 2021

Cuellar Lopez, J.S. (author), Plettenburg, D.H. (author), Zadpoor, A.A. (author), Breedveld, P. (author), Smit, G. (author)Various upper-limb prostheses have been designed for 3D printing but only a few of them are based on bio-inspired design principles and many anatomical details are not typically incorporated even though 3D printing offers advantages that facilitate the application of such design principles. We therefore aimed to apply a bio-inspired approach...journal article 2021

Smit, Chris (author)Measuring cognitive load is essential for understanding driver performance. Under- and overload can result in dangerous situations on the road. Cognitive load can be estimated by monitoring the diameter and movements of the pupils, but during measurements external influences such as changes in light intensity affect pupil diameters. In this...master thesis 2020

In this growing data environment, there is a constant search to provide more value to all data that is available for as little effort as possible. Our research tries to add such additional value by diving into the...student report 2020

Smit, Daan (author)The aim of this study is the assessment of the mechanical performance reduction due to manufacturing-induced gaps and voids (delaminations) in thermoplastic composite pipes. The effects of gaps are assessed based on the finite element modeling of an internal pressure load case and is validated by experimental tensile coupon testing. Results show...master thesis 2020

Smit, Angela (author)This thesis is about reconstructing historical vaults with cast glass. The vision is to design a complete dry-assembly cast glass arch vault where the Notre Dame de Paris is the chosen case study. The main question is: To what extent can a historical masonry arch vault be reconstructed by using cast glass components? The method is based on...master thesis 2020

Smit, Niels (author)Throughout human history deltas attract people and all other sorts of life. Inherent to this increase of delta life is the growth in conflicting values and interests. Coastal systems are not only natural systems, but can also be regarded as societal and ecological systems. Development of the coastal system inevitably leads to changes in these...master thesis 2020

Smit, Freek (author)During this thesis, 2D modelling using the MOVE software suite is performed on a fold and thrust belt in the French Prealps. The area of interest is called the Couspeau area and is 72 km2. In this area, Vocontian basin sediments deposited during the Jurassic and Cretaceous can be found. The area contains well exposed fold and thrust structures....bachelor thesis 2020

Wu, J. (author), Smit, J.J. (author), Mor, A. R. (author)In practice, High-voltage (HV) cables are occasionally exposed to impulse and superimposed transient conditions, which may initiate partial discharges (PD) temporarily. Whether such PDs persist under AC voltage after the transient conditions have vanished, is at focus in the research described in this paper. Since for cross-linked polyethylene ...journal article 2020

Akrish, G. (author), Smit, Pieter (author), Zijlema, Marcel (author), Reniers, A.J.H.M.

These models assume that different wave components are statistically independent and as a consequence cannot resolve wave interference due to statistical correlation between crossing waves, as may be found in, for...journal article 2020

Arnar Briem, Jón (author), Smit, Jordi (author), Sellik, Hendrig (author), Rapoport, Pavel (author), Gousios, G. (author), Aniche, Maurício (author)Mistakes in boundary conditions are the cause of many bugs in software. These mistakes happen when, e.g., developers make use of '<' or '>' in cases where they should have used '<=' or '>='. Mistakes in boundary conditions are often hard to find and manually detecting them might be very time-consuming for developers. While...conference paper 2020

Vertongen, J. (author), Kamper, Derek G. (author), Smit, G. (author), Vallery, H. (author)The large interest in robot hands and active hand prostheses has in recent years been joined by that in active hand orthoses. Despite the differences in intended uses, these three categories of artificial hand devices share key characteristics. Examination of the commonalities could stimulate future design. Thus, in this article, we undertook...journal article 2020

Gijswijt, Dion (author), Smit, Harry J. (author), van der Wegen, Marieke (author)There are several notions of gonality for graphs. The divisorial gonality dgon(G) of a graph G is the smallest degree of a divisor of positive rank in the sense of Baker-Norine. The stable gonality sgon(G) of a graph G is the minimum degree of a finite harmonic morphism from a refinement of G to a tree, as defined by Cornelissen, Kato and Kool....journal article 2020
