This report describes least squares estimation (LSE) and Kalman filtering in integrated navigation. The Kalman filter and its underlying principles are treated. The implementation of a Kalman filter in MIAS is investigated, and two different Kalman filters are developed. The problems that occur in a hybrid environment as the asynchronicity of...

A. construction method for codes correcting multiple localized burst errors with variable rate is proposed. The rate of a code is the ratio of the number of message symbols to the total number of symbols sent. The codes obtained by this construction method have code rate that varies with the total number of localized errors corrected. This...

Reliability analysis of the Caldicot Levels flood defence system by using Dutch reliability methods for flood defences F.A. Buijs In the light of the shift to a risk-based safety assessment of flood defences in the UK a project called RASP, Risk Assessment of Strategic Planning, is carried out at among others HRWallingford. Part of this project...

Public transport offers affordable transport to many people every day. Due to material wear down, trains can break down and stop functioning. To prevent this from happening, modern technology can used be for condition monitoring to recognize material wear down and thus allowing trains to be mended in time. The Dutch Railways approached Logica to...

The functioning of vital infrastructures, such as energy and telecommunications infrastructure, is key to societal and economic security and well-being in modern society. The reliability of these infrastructures is thus of paramount importance. Transmission system operators (TSOs) fulfill a central role in achieving this reliability, by...

Many of the assets managed by TenneT TSO have been installed in the sixties and seventies of the previous century. Consequently, 50% of their assets will reach their designed lifetime within ten years. Due to financial and technical restrictions not all the asset can be replaced based on their age. Hence, TenneT TSO developed a Health index tool...

Reliability evaluation of power system substations is of significant importance when performing asset management. Most of the studies about substation reliability only focus on the substation connectivity. The reaction of protection system is fully neglected, which cannot be true in reality. Failures of the protection system failure or the...

Introduction Floods are a threat to millions of people who live in lowlands like the Netherlands. Therefore the Dutch government has been given re-quirements for primary flood defence systems like dikes. The current condition of most of these dikes does not fulfill to these requirements based on flood risk analyses of RWS. The most logical step...

Reliability-based design is an approach currently gaining more popularity for geotechnical engineering. Neverthless, its implementation poses several challenges, one being the additional time (usually significant) in order to perform it. An important portion of this additional time comes from the need to perform many scenarios to compute the...

Petabytes of data are processed daily by distributed applications built upon Hadoop and MongoDB. A significant fraction of these applications use cloud infrastructure to cope with this vast amount of data. Commercial clouds use virtualized environments, but most distributed applications are designed around the idea that they run on physical...

The traditional Dutch way to deal with piping for river levees is the implementation of piping berms. The disadvantage of such a measure is the inland space required, especially in urban areas. Relief wells, on the other hand, require less or no inland space and therefore represent an attractive solution as mitigation measure against piping. The...

The DNV GL Health Index translates statistical, condition and utilization data of electrical power equipment into several asset representations that show technical asset health, including expected remaining lifetimes. These remaining lifetimes are used to determine the required action for the asset manager. In this research, a method was...

This thesis describes a method to find the best maintenance policy for a light rail rolling stock system based on reliability, availability, and maintenance cost. The objective of this maintenance policy is to maintain a minimum required level of system reliability at minimum maintenance cost and maximum availability. The maintenance policy...

The four blast furnace blowers at Tata Steel IJmuiden are essential for the operation of the blast furnaces. The blast blowers are steam turbines that drive large air compressors, with a power up to 37MW. In the last four years the blast blowers have suffered from a higher unplanned downtime than is acceptable for the company. This situation...

Offshore wind energy has become a very hot topic in northwest Europe, both from an industrial as from an academic point of view. Research on transmission grids for offshore wind energy focuses predominately on radial grids and HVDC. This study broadens this general scope by taken mesh grids and HVAC as the starting point. With the use of load...

Some dike sections in the Netherlands failed to comply with the safety standards and one of the most promising countermeasures is the construction of retaining walls inside the dike. The Dutch design codes for dikes with retaining walls rely on Finite Element Analysis (FEM) in combination with partial safety factors. However, this can lead to...

It was unclear what level of reliability was provided by appliance of the Eurocode load models for fatigue due to train loads, meaning that it might be insufficient. Therefore, it was investigated what the provided reliability is, compared to what is should be. Within this report, the focus is solely on fatigue induced by bending moments on...
