Visser, T. (author), Doornbos, E.N. (author), de Visser, C.C. (author), Visser, P.N.A.M. (author)Because of the highly accurate accelerometers, the GOCE mission has proven to be a unique source of thermosphere neutral density and cross-wind data. In the current methods, in which only the horizontal linear accelerations are used, the vertical winds cannot be obtained. In the algorithm proposed in this paper, angular accelerations derived...poster 2017

March, G. (author), Doornbos, E.N. (author), Visser, P.N.A.M. (author)Since 2000, accelerometers on board of the CHAMP, GRACE, GOCE and Swarm satellites have provided highresolution thermosphere density data, improving knowledge on atmospheric dynamics and coupling processes in the thermosphere-ionosphere layer. Most of the research has focused on relative changes in density. Scale differences between datasets and...poster 2017

Visser, T. (author), Doornbos, E.N. (author), de Visser, C.C. (author), Visser, P.N.A.M. (author), Fritsche, B (author)In recent studies thermospheric densities and cross-winds have been derived from linear acceleration measurements of the gradiometer on board the GOCE satellite. Our current work is aimed at analyzing also the angular accelerations, in order to improve the thermosphere density and wind data by allowing for the estimation of more unknown...poster 2016

(author)Accepted for publication in the Proceedings of the International Conference on Software Maintenance (ICSM), 2009, IEEE Computer Society. Software architecture evaluation methods aim at identifying potential maintainability problems for a given architecture. Several of these methods exist, which typically prescribe the structure of the evaluation...report 2009

Raemaekers, S. (author), Van Deursen, A. (author), Visser, J. (author)For API users, backward compatibility of new releases is important, as it permits safe and fast upgrading when the new release becomes available. To signal safe upgrading, version naming schemes such as semantic versioning provide strict rules on major (breaking changes permitted) versus minor and patch (no breaking changes permitted) releases....report 2014

Van Deursen, A. (author), Visser, E. (author), Warmer, J. (author)Software systems need to evolve, and systems built using model-driven approaches are no exception. What complicates model-driven engineering is that it requires multiple dimensions of evolution. In regular evolution, the modeling language is used to make the changes. In meta-model evolution, changes are required to the modeling notation. In...report 2007

Bouwers, E. (author), Lilienthal, C. (author), Visser, J. (author), Van Deursen, A. (author)Evaluating the complexity of the architecture of a softwaresystem is a difficult task. Many aspects have to be considered to come to a balanced assessment. Several architecture evaluation methods have been proposed, but very few define a quality model to be used during the evaluation process. In addition, those methods that do introduce a...report 2010

Visser, M.P. (author)Complex oceanographic circumstances are often found near the island of Texel. Generally, large variations occur in the water density (salinity, temperature), both in horizontal and in vertical direction, and in the course of time. Current velocity and direction are often depth dependent. Interaction between one aspect and the other is not yet...report 1977
