Schuts, M. (author), Hooman, J. (author)The high-tech industry produces complex devices in which software plays an important role. Since these devices have been developed for many decades, an increasing part of the software can be classified as legacy which is difficult to maintain and to extend. To improve the maintainability of legacy components, domain specific languages (DSLs)...conference paper 2016

Asgarpour, M. (author), Serraris, J.W. (author), de Ridder, E. (author), van den Broek, J. (author), Bos, J.E. (author)Operation and maintenance (O&M) costs contribute to a significant part of Cost of Energy produced by offshore wind. In order to reduce the O&M costs and to guarantee safety and wellbeing of the maintenance technicians, for each individual wind farm an optimal set of support vessels and access systems should be selected. This selection should...conference paper 2016

Hofman, W.J. (author)Supply - and logistics innovations require data of different, heterogeneous sources. Supply chain resilience for instance requires visibility of goods flows and data of planned infrastructure maintenance and unforeseen accidents or incidents that may cause delays. Technically, there are different ways to share this data, e.g. the messaging...conference paper 2016

de Kruif, B.J. (author)Wafer fabrication is the major cost contributor in semiconductor manufacturing. One of the steps in the fabrication is the removal of exposed layers in an automatic wet-etch station with chemicals. In time, these chemicals get polluted and their effectiveness decreases. Therefore, the chemicals in these baths need to be renewed or maintained on...conference paper 2015

(author)Corrosion in amine treating plants is known to cause integrity failures, plant shutdown, costly repairs, and so forth. The use of an amine treatment system for postcombustion CO2 capture brings additional challenges in terms of the flue gas quality, flue gas composition, operating conditions, scale of operation, and so forth. These differences...article 2015

(author)Wear and tear, electrification and aging of (low voltage) distribution grids require maintenance in order to assure continuous provision of electricity. Situational awareness is required to find out when parts of the grid need maintenance and which parts should be prioritized. The paper proposes a conceptual value model which relates sensor data...conference paper 2015

Woldman, M. (author), Tinga, T. (author), van der Heide, E. (author), Masen, M.A. (author)Machines operating in sandy environments are damaged by the abrasive action of sand particles that enter the machine and become entrapped between components and contacting surfaces. In the case of the military services the combination of a sandy environment and the wide range of tasks to be fulfilled results in extreme and uncertain operating...article 2015

Herens, M. (author), Wagemakers, A. (author), den Besten, L.A.A. (author), Bernaards, C.M. (author)Community-based physical activity programs often target women of non-Western origin, because they are relatively less active. Factors influencing physical activity initiation are widely studied. Less is known about factors influencing physical activity maintenance. More knowledge of these factors may enhance community-based physical activity...article 2015

Moerman, F. (author), Kastelein, J. (author), Centraal Instituut voor Voedingsonderzoek TNO (author)To satisfy consumer demand for "fresh-like" additive-free foods, many food producers nowadays apply mild processing and conservation techniques that often shorten the shelf-life of food, may put food at risk and may compromise consumer health. However, food legislation developed in many countries around the globe requires that microbiologically...bookPart 2014

van Zon, A.T. (author), Volker, A.W.F. (author)The concept of predictive maintenance using permanent sensors that monitor the integrity of an installation is an interesting addition to the current method of periodic inspections. Guided wave tomography had been developed to create a map of the wall thickness using the travel times of guided waves. It can be used for both monitoring and for...conference paper 2014

(author)Maintenance operations on ITER tokamak components will be largely performed by remote handling. In previous work it was shown that representative maintenance tasks could be performed significantly faster with direct visual feedback than with camera feedback. In post-test interviews, operators indicated that they regarded the lack of 3D...article 2013

Mooij, A.J. (author)Context:Large software systems are usually developed by integrating several smaller systems, which may have been developed independently. The integration of such systems often requires the development of a custom adapter (sometimes called mediator or glue logic) for bridging any technical incompatibilities between the systems. Adapter...article 2013

Polder, R.B. (author), Peelen, W.H.A. (author), Raupach, M. (author), Reichling, K. (author)This paper investigates the economic effects of full corrosion surveys of concrete structures. The background is that the existing concrete infrastructure is aging, while being exposed to aggressive influences, which increases the occurrence of corrosion and related concrete damage over time. The central proposition is that solely relying on...article 2013
