Nowadays, composites are mainly produced via petroleum derived chemicals. In a world where petroleum resources are running out, it is essential to find viable options for the replacement of these reserves. Biocomposites are already exploited but they appear to have low resistance to weathering. This …

The current research and design thesis deals with implementation of a 30-meter-long bridge with a cross section made with an innovative hybrid material composed of GFRP composite and steel members. A preliminary design consisting of analytical calculations creates a reference line on top of which FEM …

In this thesis the workings of a time-resolved setup are treated as well as the underlying physics. The setup is based on optical gating, which gives control over very short moments in time to let light pass through a gate. As this process is stable, light can be studied in very short and low intensities. …

In het najaar van 1988 werd de bever (Castor fiber L.) in de Biesbosch geherintroduceerd. De verwachting was dat de rijkdom aan plantensoorten door de komst van bevers zou toenemen, dat ermeer variatie in de vegetatiestructuur zou optreden en dat de bevers de verruiging van de vegetatie zouden tegengaan. …

Raman spectroscopy is an optical technique that is based on the inelastic scattering of light. It is non-invasive, fast, objective and easy to use. These traits make it an ideal tool for use in medical diagnosis. Melanoma is the deadliest form of skin cancer. Currently, melanomas are visually diagnosed …

This paper investigates the limits and efficacies of the Fiber Reinforced Polymer (FRP) material for strengthening mid-rise RC buildings against seismic actions. Turkey, the region of the highest seismic risk in Europe, is chosen as the case-study country, the building stock of which consists in its …

Stricter environmental policies, increased energy prices and depletion of resources are forcing industries to look for bio-based and low carbon footprint products. For industries, flax is interesting resource since it is light, strong, environmental friendly and renewable. From flax plant to fiber products …

Voor optische koppeling van glasvezels in andere optische geleiders kan een evanescent veld worden gebruikt. Een evanescent veld kan worden gestimuleerd door de glasvezels dunner te maken. Een kleine diameter resulteert in een groot veld rondom the glasvezel. Het dunner maken (tapering) kan worden …

Barges are used in order to transport all types of offshore structures and equipment. Structures which are transported are becoming larger and heavier. Therefore, there is need for barges that can handle these structures. This research will explore the possibilities to increase barge capacity by adding …

Dietary fibers are at the forefront of nutritional research because they positively contribute to human health. Much of our processed foods contain, however, only small quantities of dietary fiber, because their addition often negatively affects the taste, texture, and mouth feel. There is thus an urge …
