(author), de Dominicis, L. (author)Preventing terrorist attacks at soft targets has become a priority for our society. The realiza tion of sensor systems for automatic threat detection in crowded spaces, such as airports and metro stations, is challenged by the limited sensing coverage capability of the devices in place due to the variety of dangerous materials, to the scanning...article 2023

Binnerts, B. (author), Mulders, I. (author), Blom, K. (author), Colin, M. (author), Dol, H. (author)Autonomous Underwater Vehicles (AUVs) offer an automated solution for the collection of environmental data underwater. While they provide an effective solution in scenarios where their task is limited to basic sensor data collection, supervisory control by an operator is still needed to make more complicated decisions. Because raw data of camera...conference paper 2018

Noack, B. (author), Sijs, J. (author), Reinhardt, M. (author), Hanebeck, U.D. (author)In distributed and decentralized state estimation systems, fusion methods are employed to systematically combine multiple estimates of the state into a single, more accurate estimate. An often encountered problem in the fusion process relates to unknown common information that is shared by the estimates to be fused and is responsible for...article 2017

Verhoosel, J.P.C. (author), Spek, J.C. (author)In the Dutch SmartDairyFarming project, better decision support for the dairy farmer on daily questions around feeding, insemination, calving and milk production processes is made possible using a variety of big data sources containing static and dynamic sensor data of individual cows. This paper is concerned with the inherent semantic...conference paper 2016

Verhoosel, J.P.C. (author), van Bekkum, M.A. (author), van Evert, F.K. (author)This paper addresses the use of ontologies for combining different sensor data sources to enable big data analysis in the dairy farming domain. We have made existing data sources accessible via linked data RDF mechanisms using OWL ontologies on Virtuoso and D2RQ triple stores. In addition, we have created a common ontology for the domain and...conference paper 2015

Vonder, M.R. (author), van der Waaij, B.D. (author), Harmsma, E.J. (author), Donker, G. (author)Think big, start small. With that thought in mind, Smart Dairy Farming (SDF) developed a platform to make real-time sensor data from different farms available, for model developers to support dairy farmers in Precision Livestock Farming. The data has been made available via a standard interface on an open platform in real-time at the individual...conference paper 2015

Vonder, M.R. (author), van der Waaij, B.D. (author)The Dutch lowlands are protected by many kilometres of dikes. Currently these dikes are visually inspected on a regular basis. During heavy weather this frequency is raised, up to 24/7 in very extreme situations. After a dike failure at the Dutch town Wilnis in 2003, the question was raised whether modern sensor technology could be used to...conference paper 2013

van der Veen, J.S. (author), van der Waaij, B. (author), Vonder, M. (author), de Jonge, M. (author), Lazovik, E. (author), Meijer, R.J. (author)Sensors have been used for many years to gather information about their environment. The number of sensors connected to the internet is increasing, which has led to a growing demand of data transport and storage capacity. In addition, evermore emphasis is put on processing the data to detect anomalous situations and to identify trends. This...conference paper 2013

Brandt, P. (author), Basten, T. (author), Stuijk, S. (author), Bui, V. (author), de Clercq, P. (author), Ferreira Pires, L. (author), van Sinderen, M. (author)Much effort has been spent on the optimization of sensor networks, mainly concerning their performance and power efficiency. Furthermore, open communication protocols for the exchange of sensor data have been developed and widely adopted, making sensor data widely available for software applications. However, less attention has been given to the...conference paper 2013

van der Veen, J.S. (author), van der Waaij, B.D. (author), Meijer, R.J. (author)Sensors are used to monitor certain aspects of the physical or virtual world and databases are typically used to store the data that these sensors provide. The use of sensors is increasing, which leads to an increasing demand on sensor data storage platforms. Some sensor monitoring applications need to automatically add new databases as the size...conference paper 2012

Hinnen, K. (author), Verhaegen, M. (author), Doelman, N.J. (author), TNO Industrie en Techniek (author)Adaptive optics (AO) is used in ground-based astronomical telescopes to improve the resolution by counteracting the effects of atmospheric turbulence. Most AO systems are based on a simple control law that neglects the temporal evolution of the distortions introduced by the atmosphere. This paper presents a data-driven control design approach...article 2008

Hogervorst, M.A. (author), Toet, A. (author), TNO Defensie en Veiligheid (author)We developed a fast and efficient method to derive and apply a natural colour mapping for night-time imagery from multi-band sensors. The colour mapping is derived from the combination of a multi-band image and a corresponding natural colour reference image. The mapping optimizes the match between the multi-band image and the reference image,...conference paper 2007

Naus, H.W.L. (author), van Wijk, C.V. (author), TNO Fysisch en Elektronisch Laboratorium (author)Exploiting several arrays of sensors enables simultaneous detection of a number of emitters. Fusion of the respective array data yields lines containing possible positions as a function of the frequency. Identifying multiple intersections eventually leads to unambiguous localisation of the sources. The usual unwanted ghost detections do not...conference paper 2004
