Risto, M. (author), Martens, M.H. (author)Purpose: In-car support systems focus increasingly on improving traffic flow and throughput. Advisory systems allow for fast market penetration, advising drivers how to drive in order to improve general flow. By following the advice, drivers cannot create a beneficial effect by themselves but rely on other road users to comply as well. Drivers...article 2014

Polder, R.B. (author), Nijland, T.G. (author), de Rooij, M.R. (author), Larsen, C.K. (author), Pedersen, B. (author)road environment in The Netherlands for nearly a century. The experience is good and structures with long service lives can be obtained, as has been shown by several field studies. This is caused by a high resistance against chloride penetration and a high electrical resistivity, demonstrated both in the field and in the laboratory. Due to the...conference paper 2014

Verreault, J. (author)The Penetrator with Enhanced Lateral Effect (PELE) is a type of explosive-free projectile that undergoes radial fragmentation upon an impact with a target plate. This type of projectile is composed of a brittle cylindrical shell (the jacket) filled in its core with a material characterized with a large Poisson's ratio. Upon an impact with a...conference paper 2014

Abadjieva, E. (author), Khoe, Y.S. (author)The interaction of thin ceramic tiles with AP8 (WC core, 7,62 mm) at 1000 m/s velocity has been studied experimentally and numerically. “Thin” ceramic tiles refers here to ratio of the tile thickness (t) to the projectile diameter, (d), t/d@ 1, as they are both in the same order. The method applied to visualize the penetration dynamics has been...conference paper 2013

Beckers, A.L.D. (author), van Vossen, R. (author), Vlaming, G. (author)Naval mines and underwater improvised explosive devices in harbors can halt or block maritime transport, causing local disruptions that can impact national and regional economies considerably. Securing harbors against such threats is implemented in the Netherlands through cooperation between civil and military authorities. Existing commercial...article 2012

Mikhnenko, O.V. (author), Ruiter, R. (author), Blom, P.W.M. (author), Loi, M.A. (author)We present a new method to measure the triplet exciton diffusion length in organic semiconductors. N,N′-di-[(1-naphthyl)-N,N′-diphenyl]-1,1′-biphenyl)-4,4′-diamine (NPD) has been used as a model system. Triplet excitons are injected into a thin film of NPD by a phosphorescent thin film, which is optically excited and forms a sharp interface with...article 2012

(author)In this paper we present laboratory experiments where we address the Ground Penetrating Radar (GPR) capability of monitoring oil displacement processes in porous media. This has significant applications in near-subsurface environments where remediation of contaminant such as oil-derived liquids is considered one of the major technical,...conference paper 2011

(author)One of the shortcomings of current treatment of nerve agent poisoning is that oximes hardly penetrate the blood-brain barrier (BBB), whereas nerve agents easily do. Increasing the concentration of oximes in the brain, would therefore provide an attractive approach to improve medical countermeasures. An explanation for limited penetration might...article 2011

(author), TNO Bouw en Ondergrond (author)CO2 storage in the subsurface is becoming more and more attractive as a means to reduce CO2 emissions to the atmosphere and hence minimize human-induced global warming. The ability to monitor and verify these CO2 storage reservoirs is a key element for further implementation of other storage sites. Since the current sites fortunately do not...article 2009
