Middelburg, L.M. (author), de Graaf, G. (author), Bossche, A. (author), Bastemeijer, J. (author), Ghaderi, M. (author), Wolffenbuttel, F.S. (author), Visser, J. (author), Soltis, R. (author), Wolffenbuttel, R.F. (author)Measuring the ethanol/water ratio in biofuel of high ethanol content, such as E85, is important when used in a flex-fuel engine. A capacitive probe is generally used for measuring the ethanol/gasoline ratio. However, the water content in E85 biofuel cannot be disregarded or considered constant and full composition measurement of biofuel is...journal article 2017

Gustus, A. (author), Stillfried, G. (author), Visser, J. (author), Jörntell, H. (author), Van der Smagt, P. (author)An overview of mathematical modelling of the human hand is given. We consider hand models from a specific background: rather than studying hands for surgical or similar goals, we target at providing a set of tools with which human grasping and manipulation capabilities can be studied, and hand functionality can be described. We do this by...journal article 2012

Bijlsma, D. (author), Ferreira, M.A. (author), Luijten, B. (author), Visser, J. (author)We performed an empirical study of the relation between technical quality of software products and the issue resolution performance of their maintainers. In particular, we tested the hypothesis that ratings for source code maintainability, as employed by the Software Improvement Group (SIG) quality model, are correlated with ratings for issue...journal article 2011

Wiegmans, B.W. (author), Visser, J. (author), Konings, R. (author), Pielage, B.J.A. (author)Now, 10 years after the first plans, we analyse in this paper what has happened with Underground Logistic Systems (ULS). The major question in this paper is: Which barriers and enablers led to the failure of ULS and what ULS spin-offs can be found nowadays? Several factors can be classified as barriers or enablers. The main conclusions that can...journal article 2010

Kluyver, A.J. (author), Visser, J. (author)1. A method has been developed for testing the filtration efficiency of some filter materials. For each of the materials investigated — cotton wool, stillite and carbon — a suitable filter has been devised. 2. The filtered air was analyzed as to its germ content with the aid of a set of 3 capillary impingers. 3. The cotton wool filter gave on...journal article 1950
