The purpose of this work is as follows. Military aircraft are enormous investments for a nation. The systems lifecycle for aircraft spans decades wherein aging effects increase maintenance and operations costs over time. At some point, the deterioration of a fleet of aircraft erodes the capability of those assets below an acceptable threshold,...

Revetment systems prevent erosion of dikes. The systems need to be stable under wave attack. The size and the weight of revetment elements is the main contribution to their stability. Pattern-placed revetments consist of relatively small blocks or column-shaped natural stones or concrete elements, placed in a regular grid. The pattern creates a...

An accurate prediction of shoreline changes behind detached breakwaters is, in regard to the adjustment to the environmental impact, still a challenge for designers and coastal managers. This research is expected to fill the gaps in the estimation of shoreline changes by developing new and generalized relationships of the shoreline changes to...

The present study develops a method for the sake of evaluating Disposal and Recycle (D&R) cost in view of the increasing demand in aircraft retirement. Firstly, a process model is extracted. The subordinated cost elements are also identified. Next, the cost aggregations based on the D&R process steps are discussed. Moreover, it proposes...

Currently, task support information in aircraft maintenance is mostly provided using paper-based solutions, which are burdensome, slow and prone to error. Aircraft maintenance documentation contains vast amounts of information irrelevant for the task at hand and even for the simplest tasks multiple documents need to be consulted. Next to these...

Sustainability of electronic products until recently mainly focused on improving the energy efficiency. Recently, resource efficiency has become of growing importance. Due to the use of relatively small amounts of many valuable and scarce materials, often intimately mixed, the design of electronic products deserves specific attention. From a...

There is trend in spacecraft engineering toward distributed systems where a number of smaller spacecraft work as a larger satellite. However, in order to make the small satellites work together as a single large platform, the precise relative positions (baseline) and orientations (attitude) of the elements of the formation have to be estimated....

Dit rapport is voortgekomen uit de resultaten van een vier jaar durend destructief onderzoek naar de erosiebestendigheid van binnentaluds onder golfoverslagbelasting. Dit onderzoek is onder andere uitgevoerd met de golfoverslagsimulator. In het onderzoek is kennis ontwikkeld over de wijze waarop golfoverslag de grasbekleding van een binnentalud...

Piontkowitz, T. (author)
A large number of the dikes in the North Sea and Baltic Sea regions are covered with grass that is exposed to hydraulic loading from waves and currents during storm surges. During previous storm surges the grass cover layers often showed large strength and remained undamaged. A clear physical understanding of the failure of grass cover layers...

Inbreken via internet is een fact of life geworden. Eén van de uitdagingen voor de ICT-beveiligers is dat nieuwe inbraaktechnieken zeer snel hun weg vinden naar elke internettoegangsdeur. Professionele internetcriminaliteit is geen toekomstige bedreiging; het is volop aanwezig. Inbraaksoftware wordt in eerste instantie vaak gemaakt door...

In the low-lying coastal regions coastal defence structures are usually designed with a main function to protect the hinterland from highly vulnerable to coastal flooding. Sea dikes are usually the most common and important elements which form the coastal flood defence system. Sea dikes are designed at a pre-defined circumstance and requirement....

Experience has shown that the stability parameters relating to breakwater armour unit stability vary considerably for steep foreshores when compared to milder foreshore slope. Furthermore, the change from the deep water spectra (Tm0) to the shallow water wave spectra (Tm-1.0) does not fully explain the difference. Leading on from recent...

The Rhine River in the Netherlands, the Yellow River in China and the Mississippi River in the U.S. are three great rivers in the world. Each of them is performing a significant role in the country. The delta area for each river, in particular, is served as the centre in importance and commonly the most developed region in the whole river basin....

The wave overtopping simulator is a device which is able to simulate overtopping waves at the crest of a dike and at the inner slope. The device has been used in the ComCoast project to test a traditional dike section with grass and the SGR, the Smart Grass Reinforcement, placed in May 2006. This report describes in the first part (Chapters 1-6)...

An important element in the ComCoast concept is the overtopable sea defence, often a dike.The landward (inner) slope of the dike is adjusted in such a way that it can withstand higher overtopping rates. One of the concepts to improve the resistance is the "Sandy Dike", a cover of the inner slope with layer sand. The sand will be washed away...

In the present report field erosion tests of the inner slope of a sea dyke in the province of Groningen (near Delfzijl) are described for the situation of severe wave overtopping. Three types of tests have been performed: tests at the present grass cover, tests at a reinforced grass cover and tests at a section of bare clay. At the reinforced...
