Most ocean-going ships are fitted with an impressed current cathodic protection (ICCP) system. The currents impressed by this system onto the seawater find their way to corroding parts of the ship’s hull, and prevent the hull from corroding. The electric field resulting from the currents around the ship is called the electric signature. This...

In today's digital world, customers give their opinions on a product that they have purchased online in the form of reviews. The industry is interested in these reviews, and wants to know about which topics their clients write, such that the producers can improve products on specific aspects. Topic models can extract the main topics from large...

Manganese nodules have been lying on the deep sea soil for centuries before they became known. The first ones to discover the nodules were Murray and Renard, during their scientific cruise between 1872 and 1876 (Murray and Renard, 1876). The Clarion-Clipperton Zone, located between Mexico and Hawaii, appears to have a virtually inexhaustible...

Cobalt is one of the most important critical raw materials for emerging technologies. There are many incentives for analysis of this metal, from increasing demand for rechargeable batteries, rising prices and social issues involved. This paper is the first attempt to perform a substance flow analysis of cobalt at a city level. The analysis...

Salt caverns formed by solution mining may cause soil subsidence, because the surrounding adapts to fill the void (cavity) created in the strata. The cavern volume is hence not only a function of salt extraction (estimated from mass balance) but also a function of salt creep. The cavern size can be measured by sonar, but a less costly way would...

In the mining industry the initial capital expenditure budgeted in the feasibility study is being overrun structurally. These capital expenditure overruns have long been recognised, yet no method is available predicting the probability a mining project will experience an overrun.

This thesis introduces a method to assess the likelihood...

This study approached migration-related problems from a global perspective. The inter- connected nature of migration means that migration problems accumulate and intensify throughout the world. To capture these effects, a data-rich model component was devel- oped for global migration dynamics.
To that extent, this study has developed the...

In recent years, the offshore wind industry has grown significantly. The wind turbines are constructed in wind farms, and are serviced with relatively small crew transfer vessels. These vessels transport repair crews from the mainland to the farms and back within a day. One of the big challenges is that these transits can cause motion sickness....

Since 1918 AkzoNobel produces salt by means of solution mining from the bedded Triassic Röt Evaporite deposit in the eastern part of the Netherlands. In this technique water is pumped into the rock salt layer through a well and dissolves the halite in situ. Subsequently the brine is pumped to the purification plant at surface level where the...

Circular building has been increasing in popularity over several years. The idea being that we should not use resources only once and then discard them, but continue using them in new products. The construction industry has responded to this by designing 'circular' buildings that can be disassembled at the end of their functional life. This...

Library developers are often unaware of how their library is used exactly in practice. When a library developer changes the internals of a library, this may unintentionally affect or even break the working of the library users' code. While it is possible to detect when a syntactic breaking change occurs, it is not as easy to detect semantic...

Large material flows are extracted from natural mines in the earth’s crust and moved and stored in anthropogenic environments. Extraction processes from natural mines are often harmful for the environment and can cause material scarcity. At the same time governments are formulating ambitions to increase circularity in cities. For these reasons...

Growing markets for sustainable technologies such as solar panels, wind turbines, and electric cars require an enormous amount of raw materials that might not be available from sources on land. Exploitation of seafloor mineral resources could secure the supply of raw materials for the future. However, proposed deep-sea mining (DSM) systems will...

With a declining mining industry, Canada is looking for new models of economy. Arctic Eco-Tourism has already started growing over the last decade and is expected to grow even more rapid in future. This brings the chance of economic growth and employment. But it is also a danger¬ous situation for nature. Since the Canadian north is to more than...

In this thesis, we focus on database query processing for so-called experience items, i.e., items commonly encountered in E-Commerce systems such as books, games or movies which are better described by their perceived subjective consumption experience, or Perceptual Features, than by factual meta-data normally used in SQL-style queries. To...

In open-pit mining on a bench level, the dig-limit optimization problem is deciding whether to classify a Selective Mining Unit(SMU) as waste or whether to classify it as ore. SMU’s with high ore grades are profitable for the mining operation, but due to equipment size a whole frame of SMU’s has to be classified as either ore or waste. In this...

An efficient production is essential for an economic continuation of most gold mining companies, due to a moderate gold price and a competitive market. Recently, the Ahafo South Mining operations owned by the Newmont Mining Corporation and located on a Proterozoic gold belt in the south west of Ghana, indicated that the cost of production must...

Blasting operations form a central part of any hard rock metal mining operation, and are, given its inherent hazards, critical in ensuring safe mine working environments. In order to improve workplace safety in such operations, it is important to select the right explosives and technologies, to issue rules and procedures and to offer adequate...
