Susanto, A. (author), Koleva, D.A. (author), Copuroglu, O. (author), Van Beek, C. (author), Van Breugel, K. (author)This investigation presents a comparative study on mechanical properties, electrical resistivity and microstructure of mortar under DC current, compared to mortar in rest (no current) conditions. Monitoring was performed from 24h after casting until 84 days of cement hydration. A current density level of 10 mA/m2 was chosen as a simulation...journal article 2013

Krzeminska, D.M. (author), Bogaard, T.A. (author), Malet, J.P. (author), Van Beek, L.P.H. (author)The importance of hydrological processes for landslide activity is generally accepted. However, the relationship between precipitation, hydrological responses and movement is not straightforward. Groundwater recharge is mostly controlled by the hydrological material properties and the structure (e.g., layering, preferential flow paths such as...journal article 2013

Susanto, A. (author), Koleva, D.A. (author), Copuroglu, O. (author), Van Beek, C. (author), Van Breugel, K. (author)Corrosion in reinforced concrete structures is not only induced by the penetration of aggressive substances (e.g. chlorides and/or CO2) but also influenced by stray currents. Further, the degradation mechanisms in reinforced cement-based systems due to the combined effect of stray current and chloride penetration have been a serious problem in...conference paper 2012

Prins, R. (author), Van Beek, J. (author), Timmermans, T.T.M. (author)We, three students from the TU Delft, have created a new Secure Access Control System, named Glados. The goal of this system is to limit the access to a building, and separate 'zones' in that building, to authorized persons only. In 10 weeks, we created a prototype that can read an authentication token, and react with the permission from a...bachelor thesis 2012

Bezuijen, A. (author), Van Beek, V.M. (author), Van den Ham, G.A. (author), Zwanenburg, C. (author)Three on-going dike safety studies (on: macro stability, piping and flow slides) in the Netherlands make use of geotechnical physical models. A short outline of these projects is presented; the physical models chosen are described and discussed. The three studies use different physical models, depending on the research questions at the beginning...conference paper 2012

Van Beek, V.M. (author), Bezuijen, A. (author), Schenkeveld, F.M. (author)Piping is one of the possible failure mechanism for dams and levees with a sandy foundation. Water flowing through the foundation causes the onset of grain transport, due to which shallow pipes are formed at the interface of the sandy layer and an impermeable blanket layer. In the past, the mechanism has been investigated predominantly in...conference paper 2012

Krzeminska, D.M. (author), Bogaard, T.A. (author), Van Asch, T.W.J. (author), Van Beek, L.P.H. (author)Hydrological processes control the behaviour of many unstable slopes, and their importance for landslide activity is generally accepted. The presence of fissures influences the storage capacity of a soil and affects the infiltration processes of rainfall. The effectiveness of the fissure network depends upon fissure size, their spatial...journal article 2012

Van Beek, V.M. (author), Knoeff, H.G. (author), Schweckendiek, T. (author)Backward piping is the process of channel formation in a sandy aquifer under river dikes. During high water periods this process manifests itself by the formation of sand boils. A long history of cases and experiments has contributed to the insights into this phenomenon and has improved the ability to predict the safety of levees.book chapter 2011

The goal of this system is to limit the access to a building, and separate 'zones' in that building, to authorized persons only. Our primary concerns were security and maintainability. Special care has been taken in identifying possible attack vectors and defending against those. This...bachelor thesis 2011

Van Beek, R.B. (author)The introduction of large numbers of Electric Vehicles (EV) poses significant challenges to the power infrastructure. The combination of expected consumer recharging behaviour and the technical characteristics of the EV’s recharging power demand could potentially lead to significant increases in peak demand and cause overloads. Conventional...master thesis 2010
