Dittrich, M.G. (author), Jansen, H.W. (author)Improved methods for measuring curve squeal and braking noise have been proposed within the ACOUTRAIN project, intended as input to future standards. In this paper an outline of these methods is given and the underlying considerations are explained. The EU TSI regulation limiting noise emission of new rail vehicles does not yet specify limits...bookPart 2015

Liu, G. (author), Nielsen, E. (author), Komacka, J. (author), Leegwater, G. (author), van de Ven, M. (author)Reclaimed asphalt (RA) that contains polymer-modified bitumen (PMB) offers a potential premium material contribution for recycling. This study investigated the influence of soft virgin bitumens on the chemical and rheological properties of three reclaimed PMBs from different "old" surface-layer asphalt mixtures in Europe. Although the PMB...article 2015

Claassen, W. (author), Snijder, H.H. (author), Koot, C.J.G. (author), Maljaars, J. (author)De Hovenring is een schoolvoorbeeld van moeilijk voorspelbare trillingen. Ook wanneer wel direct voorzieningen waren opgenomen in het ontwerp, dan nog zou de problematiek zich hebben aangediend. In de praktijk bleken trillingen op te treden met hoge spanningsranges in grote aantallen, die volgens de analyses op basis van de norm vooraf niet...article 2015

Jacobs, P. (author), Borsboom, W.A. (author)People spend more than 80% of their time indoors. In contrast to ambient air, no (legal) limits for indoor particulate matter exist, although there are WHO guidelines. In the Netherlands a measurement protocol to determine the PM2.5 in office buildings has been developed including 5 quality classes. However at the moment no simple guidelines or...conference paper 2015

(author), Volten, H. (author)In this paper, the use of a neural network algorithm for the retrieval of the aerosol properties from ground-based spectropolarimetric measurements is discussed. The neural network is able to retrieve the aerosol properties with an accuracy that is almost comparable to that of an iterative retrieval. By using the outcome of the neural network as...article 2015

Walraven, J. (author), Vrouwenvelder, A.C.W.M. (author)Tot voor kort leefde Nederland mee met de gevolgen van aardbevingen in de wereld, in de veronderstelling dat dit ver van ons bed was. Door de recente aardschokken in Groningen zijn in ons land andere ideeën ontstaan over de invloed van aardbevingen op de gebouwde omgeving. In dit artikel worden de herkomst en de karakteristieken van de Groninger...article 2015

Jonson, J.E. (author), Jalkanen, J.P. (author), Johansson, L. (author), Gauss, M. (author), van der Gon, H.A.C.D. (author)Land-based emissions of air pollutants in Europe have steadily decreased over the past two decades, and this decrease is expected to continue. Within the same time span emissions from shipping have increased in EU ports and in the Baltic Sea and the North Sea, defined as SECAs (sulfur emission control areas), although recently sulfur emissions,...article 2015

Yang, Z. (author), Fischer, H. (author), Polder, R.B. (author)In this paper, two types of modified hydrotalcites (MHT) were incorporated into cement mortars with two dosage levels (replacing 5% and 10% cement by mass). Designated testing programme including strength test, porosity test, and rapid chloride migration and diffusion test were employed to investigate the effect of modified hydrotalcites on...article 2015
