Lateral torsional buckling in translational and rotational compliant joints to obtain zero-stiffness behaviour

Compliant mechanisms are a popular alternative to conventional mechanisms because of their advantages on mass reduction, friction, backlash and lubrication. However, the major drawback in the use of compliant mechanisms is the stiffness is the desired direction of motion. The advantages of conventional and compliant mechanisms can be combined if...

The Future of Structuralism: Hidden Beauty

How does a brick arch become part of a structuralist building? In this project I unravel the material layers of Van Stigt's Leiden Faculty and add a new architectural language that reappreciates the craftmanship behind brickwork.

The New Vorarlberger Einhof

A CANS-preventing posture-coaching shirt accompanied by an application that is positioned in a world of professionals

Goal of the graduation project is to make a market proposition for an existing innovative product, the FysioPal. This is done by researching the internal and external market environment as well as the stakeholders that can be influencing in the business model network of the product-service FysioPal. By combining the insights found internal as...

Structural and mechanical characterization of the peri-prosthetic fibrous membrane

In this pilot study, we obtained the peri-prosthetic fibrous membrane of eleven patients undergoing hip revision surgery due to aseptic loosening. We investigated the molecular content of the tissue by real-time PCR (RT-PCR) and the structural properties by histology and confocal microscopy. Atomic force microscopy (AFM) and nanoindentation were...

Drinking water temperature modeling in domestic systems

Domestic drinking water systems are the final stage of the transport process to deliver potable water to the customers tap. Although these systems play an important role in drinking water quality only several researches on the edge of residence time and temperature were performed during the past. These two parameters play an important role in...

Developing the bridge championship table of the future

Developing a new bridge championship table and exploring the world of the card game contract bridge. An analysis of the present used table, the surroundings of the product and the users is done to find problems and possible improvements that can be done. Resulting in a redesigned innovative championship table.

Long-term morphological modelling of the mouth of the Columbia River

With the construction of a process-based long-term morphological model (Delft3D) for the Mouth of the Columbia River (MCR), a first approach is made in trying to simulating the long-term morphodynamics of the MCR. Focus is on simulating the observed morphological changes for the post-jetty period of 1926-1958. The model is supplied with a high...

Fieldwork coastal engineering: Preliminary design of a floating marina, Varna, Bulgaria

The beach in front of the hotel Sirius is suffering from a retreating coastline. Bathymetry and beach profiles were measured. With the data from previous years the long term evolution of the coast was analyzed. The main conclusions were that the beach in front of the Sirius hotel is still suffering from erosion and if this erosion trend...
