Zhou, C. (author), Liu, X. (author), Apostolidis, P. (author)Low Temperature Asphalt (LTA) technologies are utilized in asphalt pavement industry to lower energy demands and greenhouse gas emission during mixing and construction processes. Although these technologies are currently available and hope to demonstrate similar performance with Hot Mix Asphalt (HMA) mixes, LTA shows more sensitive than HMA to...conference paper 2017

Wang, Guijie (author), Heidari, A. (author), Makinwa, K.A.A. (author), Meijer, G.C.M. (author)This paper describes the design of a precision bipolar junction transistor based temperature sensor implemented in standard 0.7-μmCMOS technology. It employs substrate p-n-ps as sensing elements,which makes it insensitive<br/>to the effects of mechanical (packaging) stress and facilitates the use of low-cost packaging technologies. The sensor...journal article 2017

Phan Hien, V. (author), Lindenbergh, R.C. (author), Menenti, M. (author)Monitoring glacier changes is essential for estimating the water mass balance of the Tibetan Plateau. In this study, we exploit ICESat laser altimetry data in combination with the SRTM DEM and the GLIMS glacier mask to estimate trends in change in glacial thickness between 2003 and 2009 on the whole Tibetan Plateau. Considering acquisition...journal article 2017

Lommen, S.W. (author)This dissertation has investigated whether a combination of DEM and MBD can be used for a reliable and accurate environment for predicting grab unloading performance. A grab is a type of bulk material handling equipment used for unloading materials such as coal and iron ore from vessel to shore. Both a grab and iron ore pellets have been...doctoral thesis 2016

Derakhshani, S.M. (author)Dust has negative effects on the environmental conditions, human health as well as industrial equipment and processes. In this thesis, the transfer point of a belt conveyor as a bulk material handling system with a very high potential place for dust liberation is studied. This study is conducted based on experimental and numerical methods as...doctoral thesis 2016

Jonker, C. (author)The recent emergence of Light Detection And Ranging (LiDAR) scanning technology has resulted in the availability of very large three dimensional point cloud data sets. These LiDAR data sets have become a main source for the modeling and reconstruction of both ground surface as well as above-ground objects such as buildings and vegetation. For...master thesis 2016

Le, N.L.B. (author), Stroeven, P. (author), Stroeven, M. (author), Sluys, L.J. (author)Details of a complete methodology for porosimetry of virtual concrete have been described in a series of publications. This paper shortly sketches the main characteristics, whereupon it is indicated how a pore network model is designed based on data extracted from the virtual cement paste. This involves smoothing the main trunks as the main pore...conference paper 2015

Li, K. (author), Stroeven, P. (author), Stroeven, M. (author), Sluys, L.J. (author)Permeability of virtual cement seems to exceed experimental data by several orders of magnitude. The differences may actually not be that dramatic, since experimental samples are in practice not always fully saturated as generally assumed. This paper demonstrates that this has enormous effects on permeability. A numerical study is conducted on...conference paper 2015

Li, K. (author), Stroeven, P. (author), Le, L.B.N. (author)A novel methodology is described for porosimetry as well as for water transport through the pore system in dynamic DEM-based virtual cementitious materials. The pore network topology, the pore size distribution and the pore connectivity are assessed on the basis of a robotics-inspired pore delineation method and star volume measurements....journal article 2015

Stroeven, P. (author), Le, L.B.N. (author)Porosimetry of matured cementitious materials is of hiigh interest, because durability is governed by the capillary pore network structure. Experimental approaches are time-consuming, laborious and thus expensive. Fast developments in computer technology make it nowadays possible quite realistically producing cementitious materials in virtual...conference paper 2013
