Many firms are occupied with determining the optimal replacement time of machinery. Machine replacement is a complex investment decision that requires the estimation of future cash flows and other parameters. The non-deterministic character of future cash flows has given rise to stochastic models, that take into account this uncertainty. This...

In contrast with other Dutch rivers parts, human measures in the upstream part of the River Meuse did not mainly focus on discharging surplus water, but on retaining water in dry periods. Almost 100 years ago seven weirs were constructed in the River Meuse to enable transport of coals. The structures reach, due to concrete degradation, the end...

Asset degradation and maintenance strategies are driving factors that cause the variation in life cycle cost (LCC) of infrastructure assets. In the railway industry, several researchers have analyzed the impact of the uncertainty on LCC, but the emphasis was laid on traditional ballasted tracks. Another type of track structure, embedded rail...

Bridges are a crucial part of the dense Dutch highway network. Almost 50% of the current bridges are built between 1960 and 1980 for an intended service life of 50 years and thus they might reach the end of their lifetime in the near future. This strongly indicates that a large challenge can be expected regarding infrastructural replacement.<br/...

When people experience pain, discomfort or motion limitation in their hip joint they can get a hip implant. This implant improves the movement and decreases the pain and discomfort. Due to several reasons such an implant needs revision after ten to fifteen years. This revision surgery is a long and invasive surgery. When an implant is fixated...

This thesis report presents an investigation of a soil improvement technique that is being executed for a Van Oord project in Kuwait. The soil is improved by the use of a column supported embankment, consisting of sand columns installed in a soft soil layer and a sand platform. The efficiency of this method is defined in terms of stress transfer...

Introduction. Aseptic loosening is indicated as the main cause of knee implant failure. Despite all currently used techniques, it remains challenging to diagnose an aseptic loose knee implant. A promising technique to reveal aseptic loose related implant motions is inducible displacement (ID). ID measurements are used to detect implant motion...

At the dawn of a large infrastructure replacement program in the Netherlands the question rises whether current forms of public-private partnerships in infrastructure projects are sufficient to deal with the complexities involved in large scale replacement of water infrastructure objects. It is stated that the concept of public private...
