For certain geotechnical structures, such as dikes and levees, the design quality is heavily reliant on the sampling quality. In addition, the extent of consequences on geotechnical design of using parameters from samples with a certain degree of disturbance in laboratory tests is unclear. While the available literature has been mainly focussed...

Analysing the contact area between head-related products and the corresponding craniofacial profile is necessary to make such products more comfortable. The study of soft tissue biomechanical experiments provides a reliable perspective for understanding such contact areas and improving the comfort. In order to obtain more accurate and visualized...

Diagnosis of ankle impingement is performed primarily by clinical examination, whereas medical imaging is used for severity staging and treatment guidance. The association of impingement symptoms with regional three-dimensional (3D) bone shape variaties visible in medical images has not been systematically explored, nor do we know the type...

In this study, we targeted a calcium hydroxide and ettringite composite-type expansive additive (EA) and obtained the basic characteristics of the EA mixed cement paste in order to create a method for calculating volume expansion based on the hydration reaction of the PCEA system. Expansion strain, setting time, and compressive strength were...

Rolling contact fatigue (RCF) is an important form of damage in wheels and rails that typically has surface and subsurface cracks. Squats are one of the major RCF defects that occur in the running band of rails and can create high dynamic forces and cause rail fracture if they are not detected and treated in time. In the current research, three...

This project is initiated by Stan Buckens, a radiologist from the RadboudUMC, who believes in realizing passive four-dimensional (4D) CT scans for the wrist. At this moment the wrist is mainly scanned and reviewed statically in 3D. However, it is desirable to see what happens on a CT scan during movement (the fourth dimension) of the wrist, as...

One of the main drawbacks of crumb rubber modified bitumen (CRMB) is the storage stability issue. The storage instability of CRMB impedes its further application. This study aims to develop a robust methodology to evaluate the storage stability of CRMB binders using both mechanical and morphological tests. The effects of rubber contents (0, 5...

This study investigates the angles θ<sub>1</sub>, θ<sub>2</sub>, and θ<sub>3</sub> that squat crack faces form with respect to three orthogonal planes: the rail top, the longitudinal-vertical cross-section and the lateral-vertical cross-section. Rail samples with squats of various severities are obtained from the field. Their three...

Chemical Enhanced Oil Recovery (CEOR) methods can increase the oil recovery of a reservoir to more than 60% of the volumes originally in-situ. Typical oil recoveries range from 20% to 40% of OIIP under traditional primary and secondary recovery stages. The understanding of the mechanisms that control such complex processes is essential...

Surfactant-alternating-gas (SAG) is a favored method of foam injection, in part because of excellent gas injectivity. However, liquid injectivity is usually very poor in SAG. We report a core-flood study of liquid injectivity under conditions like those near an injection well in SAG application in the field, i.e., after a prolonged period of gas...

We study the potential formation damage effects due to radial jet drilling on Bentheim sandstone, a homogeneous sandstone that is well established in terms of mechanical properties and widely used as reservoir analogue. We quantify how properties degrade with distance from a jetted hole on μm scale (porosity) and cm scale (compressive, tensile...

Dilatant fractures and faults in carbonate rocks play an important role as fluid path for many applications. However, multidimensional characterization of these fractures remains a challenge due to structural complexity in multiscale. The progressive deformation of dilatant fracture in normal fault system from physical models are imaged in 3D...

In opdracht van Vlaamse Maatschappij voor Sociaal Wonen (VMSW) heeft ADC ArcheoProjecten een archeologische opgraving uitgevoerd voor het plangebied Oudenaarde-Heurnestraat. Op het terrein zijn de VMSW en Sociale Huisvestingsmaatschappij Vlaamse Ardennen voornemens een verkaveling te realiseren. Een archeologische prospectie wees uit dat er...

Hydraulic timber structures such as mooring poles, fenders, quay walls, lock gates and jetties are widely used in inner and marine harbours all over the world. In general, these structures give satisfactory performance with regard to the technical requirements. Because of the harsh exposure conditions such as brackish and contaminated water,...

This thesis aims at investigating the effect of a thermal shock of a couple of hundred degrees on the creation of the thermal microfractures and in what way the mechanical properties of volcanic rocks change. In the geothermal field, thermal microfractures can contribute to increase the permeability and produce more steam to the surface. We...

This paper evaluates a method that improves segmentation e ciency by intelligently suggesting planes where correction is most valuable. An existing method is extended to work for segmentation of multiple bones simultaneously. This method is evaluated because in clinical practice it is often necessary that scans are segmented very accurate. When...

Reinforcement corrosion is the most important deterioration mechanism affecting reinforced concrete infrastructures. After corrosion starts, expansive pressures are exerted onto the surrounding concrete, causing cracking and spalling of the cover concrete. The amount of cover cracking can possibly be reduced by using strain hardening...

Asphalt concrete is a viscoelastic material consisting of aggregates, filler and bitumen. The response of asphalt concrete is highly dependent on temperature, loading rate and confining pressure. Permanent deformation is one of the most important distresses developing during the flexible pavement service life. The total deformation which is...

Gas has proved to be a successful extractable hydrocarbon resource from shale in the United States. In Europe results have so far been disappointing, but with increasing global energy demand a lot of interest remains in the potential of recoverable shale gas reservoirs. However, the way how the economic potential of shale is mapped is...
