Building Resilience: Analyzing Beira’s Drainage Network and Flood Management: The impact of failure mechanisms on flooding in informal settlements

This research analyses and evaluates the performance of the drainage system in Beira, Mozambique. It considers its formation, maintenance, failure modes and connections, to recommend improvements on its performance. The research identifies six primary failure modes - vegetation overgrowth, human interference, waste accumulation, sedimentation,...

The Hydraulic WILMER Tweezer: Design and Development of a Hydraulic Voluntary Closing Mechanism within a Body Powered Split-Hook Prosthesis

Background Despite its high demand, prostheses are too often abandoned because they fail to meet the main requirements control, comfort and cosmesis. Body-powered hook prostheses provide good control due to their proprioceptive feedback but are in general not efficient nor appealing. The WILMER group has developed an appealing voluntary-opening...

A New Take on Prosthetic Wrists: The Development of a 3 DoF, Hydraulically Powered Wrist Prosthesis

Background: While new prosthetic hands are developed to increase functionality and allow more complex movements, prosthetic wrists are researched less. Although there are wrists available, primarily featuring 1 degree of freedom (DoF), only a few prototype 3 DoF wrists are currently known. These 3 DoF wrists usually have sufficient range of...

Creating a Miniature Hydraulic System to Power the Delft Cylinder Hand

To reduce the necessary input force of the user to exert a precision grip force above 30 N, the hydraulic circuit of the Delft Cylinder Hand can be expanded. This added hydraulic circuit has to be able to generate high enough pressures and volume flows to generate a pinch force of 30 N with all of the fingers, close the hand within 0.5 seconds...

Observing Solid Concentrations in a Vertical Hydraulic Transport System

At large oceans depths (5000m) manganese nodules are formed, these are rock shaped objects that contain various rare earth metals, Royal IHC is currently developing equipment to bring these nodules to the shore. The nodules will be transported to the water surface using a Vertical Transport System (VTS).<br/><br/>In the VTS insight of the...

Feasibility Study on Deep Seawater Solutions for Manado: ROTEC

Due to climate change and growing cities, water scarcity is becoming one of the futures biggest problems. On top of that, the population and prosperity of cities around the equator are growing fast. Meaning that the need for electricity, cooling and drinking water will grow fast in the following decades. ROTEC’s vision is that these growing...

Energy Storage: It's inevitable, Gravity Power: A preliminary feasibility study

This paper has been written for everyone that is interested in the topic of energy and consists of part one and part two. Attempted has been to write this paper in such a way so that it’s easy to follow for everyone. Part one, the non-technical part, should be an easy read for everyone. Part two, on the other hand, is a technical report,...

Coal transport Kalimantan, research on different alternatives for coal transport in the province of South Kalimantan, Indonesia.

This master thesis focuses on the transportation of coal from two coalmines in South Kalimantan to the Java sea. Coal has to be transported from the coal mine area, situated hundred kilometre land inward, to a location with sufficient water depth, at the mouth of the river Barito. The biggest challenge for the new transport system is to increase...
