Mechelse, Eelco (author)Knowledge of the state of stress is of significant importance to have a thorough understanding of subsurface geomechanics. The World Stress Map (WSM) is the main source of present-day stress data in Western Europe and indicates a regional NW-SE maximum horizontal stress (SH) trend for the Netherlands. However, for more local studies the WSM...master thesis 2017

Elghlan, Faris (author), van Leest, Timo (author), van den Berg, Michiel (author)Note: some parts of the abstract have been censored to hide company secrets.<br/><br/>This project was performed for Orchid N.V., an innovator in agriculture. The project focuses on their Scalar system. This is a system that consists out of multiple machines that automatically feed cows. While farmers are generally pleased with these systems, --...bachelor thesis 2017

Wieman, R. (author)Analyzing large numbers of log entries can be challenging, especially when there are many short log entries that each describe only one execution of the system, either successful or unsuccessful. How can one determine whether the system is working correctly, based on these logs? The logs that are of interest (e.g., log entries pointing towards...master thesis 2017

Evers, P. (author)Logs play an important role in debugging and maintaining large applications. When a system fails, developers investigate the log records to gain insight to identify the problem. Traditionally developers used tools like grep and tail to identify irregular behavior. This approach is time consuming for large companies that can generate over 600GB...master thesis 2017

Aué, Joop (author)Using logs to detect and diagnose problems in software systems is no longer a feasible human process. The ever increasing amount of logs produced by present-day systems calls for more advanced techniques to enable log analysis. A great deal of log research has since then been focused on abstracting over log messages, clever analysis techniques...master thesis 2016

Ooms, M.C. (author)The Collisional Orogeny in the Scandinavian Caledonides (COSC) drilling project, supported by the International Continental Drilling Program (ICDP) and Swedish Research Council, was designed to study mountain building processes and the geologic structure and composition of the Caledonian orogeny in central Sweden. The 2.5 km deep scientific COSC...master thesis 2016

Hendriksen, H. (author)Financial fraud is, within the banking world, a major source of expenses. Improving on timely detecting fraud is a constantly ongoing cat and mouse game between the financial institutions and criminal organisations. To be on the edge of fraud detection, new approaches have to constantly be developed. This research will tap into the large amount...master thesis 2016

Brenkman, C.F. (author)Anomaly (or outlier) detection techniques can be used to find occurrences in data that are surprising or unusual, arousing the suspicion of being generated by an aberrant mechanism. A collective anomaly is a collection of data instances of which the individual data instances may not be anomalies by themselves, but their occurrence together is...master thesis 2015

Guijt, D.J. (author)One of the standard features of today’s major Web search engines are query suggestions, which aid the user in the formulation of their search queries. Over the years, a number of different approaches have been proposed that have com- monly been evaluated in the standard Web search setting. In this thesis, we build a query suggestion pipeline...master thesis 2014

Liu, J. (author)“If you could relive a moment of your life, what would it be?” Beautiful moments are constantly happening in everyone’s life and the answer for this question can be different from person to person. Big life events such as wedding, graduation, the birth of your child, are certainly those memorable moments. But our life is also full of moments...master thesis 2014

Van der Boor, M.C. (author)In clastic rock, the interpretation of facies from the spectral gamma-ray log should be applied with caution because a consistent relationship with gamma-ray is lacking due to variations in provenance and/or diagenesis. In this thesis the use of the gamma-ray log for the derivation of source rock characteristics and/or diagenesis is examined....master thesis 2014

Ogg, W. (author)Just like many other shallow marine fields, the Troll field is steadily increasing its recovery factor by performing an extensive infill drilling procedure. Well planning requires an ever increasing knowledge of the geological and sedimentary characteristics of the field, as higher drilling precision demands a more detailed reservoir model. The...master thesis 2013

Siadis, J. (author)Checking the execution behaviour of continuous running software systems is a critical task, to validate if the system is behaving as expected. In order to facilitate this process, many companies from the industry utilize log mechanisms to record events of interest and analyze the data in a post-mortem fashion. However, employing logging...master thesis 2013

Jain, P. (author)This thesis proposes and evaluates a concept for downhole depth estimation by matching subsurface measurements from two sensors in a bottom hole assembly. The application of a downhole depth estimate in automated subsurface navigation has also been demonstrated. One of the key hurdles in achieving real time subsurface navigation lies in...master thesis 2013

Muijs, E.S. (author)Publications of bipolar log-amp detectors for RF power detection show good temperature and RF performance. So far published CMOS log-amps fail to demonstrate accurate performance over temperature.

Boogaerdt, N.M. (author)Geological data is often compositional (i.e. positive and sum to unity). The constrained nature of compositional data can lead to severe problems during data analysis. Transforming from the simplex to centered log-ratio (CLR) space can solve these problems, converting constrained non-linear processes into unconstrained linear processes ...master thesis 2012
