Esposito, R. (author), Hendriks, M.A.N. (author)The Alkali-Silica Reaction is a harmful reaction which can compromise the integrity and capacity of concrete structures. Due to its nature, a multiscale material model has been chosen to perform structural analyses. The model aims to couple the chemical and mechanical effects in order to characterize the affected concrete into the structures,...conference paper 2013

Esposito, R. (author), Hendriks, M.A.N. (author)One of the most harmful degradation process for concrete structures is the alkali-silica reaction. This process starts at aggregate level with a gel swelling and can produce damage up to macro level, by compromising the integrity and capacity of the structure. In order to better understand the complex nature of this phenomenon, a multiscale...conference paper 2013

Belletti, B. (author), Damoni, C. (author), Hendriks, M.A.N. (author)Three years ago, the Dutch Ministry of Infrastructure and the Environment initiated a project to re-evaluate the carrying capacity of existing bridges and viaducts (e.g. reinforced and pre-stressed concrete beams and slabs). Due to the increase of traffic and the reallocation of emergency lanes to traffic lanes, the safety verification of some...conference paper 2013

Kappen, J.M.J. (author), Giardina, G. (author), Hendriks, M.A.N. (author), Rots, J.G. (author)The development of infrastructure in major cities often involves tunnelling, which can cause damage to existing structures. Therefore, these projects require a careful prediction of the risk of settlement induced damage. The simplified approach of current methods cannot account for three-dimensional structural aspects of buildings, which can...conference paper 2013

Slobbe, A.T. (author), Hendriks, M.A.N. (author), Rots, J.G. (author)This paper presents a dedicated numerical test that enables to assess the directional mesh bias of constitutive models in a systematic way. The test makes use of periodic boundary conditions, by which strain localization can be analyzed for different mesh alignments with preservation of mesh uniformity and with exclusion of boundary disturbances...conference paper 2013

Belletti, B. (author), Damoni, C. (author), Hendriks, M.A.N. (author), Den Uijl, J.A. (author)According to the new fib Model Code 2010 the design shear resistance of a reinforced concrete (RC) structure can be evaluated through analytical and numerical calculation methods that fall into four different levels of approximations; the complexity and the accuracy of the calculated shear resistance increases with increasing the level of...conference paper 2013

Van der Maaten, L.J.P. (author), Hendriks, E.A. (author)Automatic facial expression recognition is an important problem in social signal processing that has applications ranging from treatment of autistic children to monitoring of conflict situations [6]. In psychology, facial expressions are generally described using the Facial Action Coding System (FACS; [2]), in which each facial muscle is...conference paper 2012

Esposito, R. (author), Hendriks, M.A.N. (author)The Alkali-Silica Reaction (ASR) can generate harmful effects in the concrete structures. In this paper the degradation of the mechanical properties of ASR-affected concrete is studied by comparing the experimental results available in literature. An overview of the macroscopic material modelling approaches related to this aspect is given....conference paper 2012

Esposito, R. (author), Hendriks, M.A.N. (author)In this paper the anisotropic behavior of ASR swelling is simulated through a 1D smeared crack model. The choice of the engineering properties is discussed, in particular for the evolution of the tensile strength and the Young’s modulus during the swelling. The last one is used as the main indicator for ASRrelated damage. The model is hampered...conference paper 2012

(author)This paper outlines a project (namely PAT-ASR) which entails the development of a multi scale material performance assessment model on simulation of alkali silica reaction deployment and its effects on concrete durability. Performance models require a multi scale approach from micro (namely reaction chemistry) to macro level studies (namely...conference paper 2012

Huo, F. (author), Hendriks, E. (author), Paclik, P. (author)Until now, most of the computer games are played with a controller. But there is a big difference between pushing a button to jump and jumping yourself. Currently we are developing new tools which allow players to get rid off controllers and play games using intuitive body movements and poses. In this demo, we illustrate real-time pose tracking...conference paper 2011

(author)The paper presents an extension of active appearance models (AAMs) that is better capable of dealing with the large variation in face appearance that is encountered in large multi-person face data sets. Instead of the traditional PCA-based texture model, our extended AAM employs a mixture of probabilistic PCA to describe texture variation,...conference paper 2010
