Running robots at insect scale are an upcoming research field, because of their numerous potential applications like exploration of hazardous environments such as collapsed buildings, natural disaster sites and debris. To date no report exists on such a robot that either exploits its resonance, or that is monolithic. These properties, however,...

This paper presents a new monolithic free-surface formulation that exhibits correct kinetic and potential energy behavior. We focus in particular on the temporal energy behavior of two-fluids flow with varying densities. Correct energy behavior here means that the actual energy evolution of the numerical solution matches the evolution as...

Recently, a monolithic scintillator detector for time-of-flight (TOF)/depth-of-interaction (DOI) positron emission tomography (PET) was developed. It has a detector spatial resolution of ∼1.7 mm full-width-at-half-maximum (FWHM), a coincidence resolving time (CRT) of ∼215 ps FWHM, and ∼4.7 mm FWHM DOI resolution. Here, we demonstrate, for the...

In order to collect validation data for the study of the mechanism of fluid-structure interaction (FSI), an lab experiment was conducted by L. Rizos in the towing tank, 3ME,TUDelft in 2016. The concept of the experiment is shown in the figure 1. A cylindrical container is partially filled with water. A small cylindrical oscillator with flexible...

We have recently built and characterized the performance of a monolithic scintillator detector based on a 32 mm × 32 mm × 22 mm LYSO:Ce crystal read out by digital silicon photomultiplier (dSiPM) arrays coupled to the crystal front and back surfaces in a dual-sided readout (DSR) configuration. The detector spatial resolution appeared to be...

The benefit of two-terminal multijunction solar cells in regard to the number<br/>of junctions (subcells) is critically evaluated. The optical and electrical losses<br/>inherent in the construction of multijunction cells are analyzed using information<br/>from thin-film silicon photovoltaics as a representative case. Although<br/>the...

New applications for positron emission tomography (PET) and combined PET/magnetic resonance imaging (MRI) are currently emerging, for example in the fields of neurological, breast, and pediatric imaging. Such applications require improved image quality, reduced dose, shorter scanning times, and more precise quantification. This can be...

Gamma-ray detectors based on thick monolithic scintillator crystals can achieve spatial resolutions &lt;2 mm full-width-at-half-maximum (FWHM) and coincidence resolving times (CRTs) better than 200 ps FWHM. Moreover, they provide high sensitivity and depth-of-interaction (DOI) information. While these are excellent characteristics for...

Gamma-ray detectors based on bright monolithic scintillation crystals coupled to pixelated photodetectors are currently being considered for several applications in the medical imaging field. In a typical monolithic detector, both the light intensity and the time of arrival of the earliest scintillation photons can be recorded by each of the...

Distinguished Dunes is an ambitious, yet realistic design for a crematorium within the Coepelduynen. It makes the most of the opportunities offered by its program, the present natural forces and high-end technology. These three parameters leads to a very pure and clean building that takes its responsibility for its direct environment, spatial...

Fibre reinforced polymer composites are applied in monolithic sandwich elements that function as bearing structure in unitised façade systems. The research covers a complete system analysis of the concept, a material assessment regarding engineering FRP composites, and the accompanying quality assurance for both the materials and the production...

The performance of heterogeneous catalysts in multiphase reactions in general is governed by different types of extrinsic and intrinsic structural effects on all length scales, i.e., on the macro- (m to cm), meso- (mm to µm), and microlevel (nm). This PhD research, with a catalysis-engineering approach, focused on several of these multiscale...

This paper highlights the importance of achieving durable and long-term predictable repair of reinforced concrete structures. The performance of concrete repair in past and current engineering practice, including all types of repair and application of different materials, is often unsatisfactory. One of the reasons for this lays in the fact that...

Positron emission tomography (PET) is one of the key medical imaging modalities in the diagnosis and staging of e.g. cancer and cardiovascular diseases. The image formation is based on the measurement of annihilation photon pairs in the detector ring of the PET scanner. The diagnostic value of a PET image depends crucially on the image quality,...

The Monolithic Stirrer Reactor (MSR) is a novel concept for heterogeneously catalyzed reactors and is presented as an alternative device to slurry reactors. It uses a modified stirrer on which structured catalyst supports (monoliths) are fixed to form permeable blades. The monoliths consist of small square parallel channels on which a layer of...

The majority of existing problems within conventional prosthetic fingers are related to the use of conventional rigid links and kinematic joints and to the lack of adaptability of the finger. In this paper these problems are solved by the design of a fully compliant under-actuated prosthetic finger. At first a basic structure was defined....

Monolithic scintillator detectors are very promising for high-resolution high-sensitivity PET. These detectors consist of several cubic centimetres of scintillating material coupled on one or more sides to position-sensitive avalanche photo-diode (APD) arrays. The coordinates of the entry point of an incoming gamma photon are estimated from the...

Positron emission tomography (PET) is a technique for imaging the 3-dimensional distribution of radio-labelled molecules in vivo. This technique plays an increasingly important role in preclinical research involving mice and rats. The small dimensions of these animals impose stringent requirements on both the image resolution and the sensitivity...
