Rajabzadeh, Aydin (author), Groves, R.M. (author), Hendriks, R.C. (author), Heusdens, R. (author)In this paper the behaviour of fibre Bragg grating (FBG) sensors under non-uniform strain distributions was analysed. Using the fundamental matrix approach, the length of the FBG sensor was discretised, with each segment undergoing different strain values. FBG sensors that are embedded inside composites, also undergo such non-uniform strain...conference paper 2017

van Kuyk, Steven (author), Kleijn, W.B. (author), Hendriks, R.C. (author)Instrumental measures of speech intelligibility typically produce an index between 0 and 1 that is monotonically related to listening test scores. As such, these measures are dimensionless and do not represent physical quantities. In this paper, we propose a new instrumental intelligibility metric that describes speech intelligibility using bits...conference paper 2016

Zhang, J. (author), Hendriks, R.C. (author), Heusdens, R. (author)Auto-localization in wireless acoustic sensor networks (WASNs) can be achieved by time-of-arrival (TOA) measurements between sensors and sources. Most existing approaches are centralized, and they require a fusion center to communicate with other nodes. In practice, WASN topologies are time-varying with nodes joining or leaving the network,...conference paper 2016

Khademi, S. (author), Hendriks, R.C. (author), Kleijn, W.B. (author)The processing required for the global maximization of the intelligibility of speech acquired by multiple microphones and rendered by a single loudspeaker, is considered in this paper. The intelligibility is quantized, based on the mutual information rate between the message spoken by the talker and the message as interpreted by the listener. We...conference paper 2016

Koutrouvelis, A. (author), Hendriks, R.C. (author), Jensen, J (author), Heusdens, R. (author)We propose a new multi-microphone noise reduction technique for binaural cue preservation of the desired source and the interferers. This method is based on the linearly constrained minimum variance (LCMV) framework, where the constraints are used for the binaural cue preservation of the desired source and of multiple interferers. In this...conference paper 2016

Esposito, R. (author), Hendriks, M.A.N. (author)The alkali-silica reaction (ASR) is a long-term deterioration process, which produces a hydrophilic and expansive gel causing damage. The ASR acts on concrete as an ageing phenomenon, modifying the material on the basis of its stress state. Focussing on the mechanical degradation of concrete, estimated trends for the mechanical properties in...conference paper 2016

Zhang, J. (author), Hendriks, R.C. (author), Heusdens, R. (author)Randomized gossip (RG) based distributed averaging has been popular for wireless sensor networks (WSNs) in multiple areas. With RG, randomly two adjacent nodes are selected to communicate and exchange information iteratively until consensus is reached. One way to improve the convergence speed of RG is to use greedy gossip with eavesdropping (GGE...conference paper 2016

Vidal Sarmiento, E. (author), Hendriks, M.A.N. (author), Geiker, M. R. (author), Kanstad, T. (author)Most recent studies on fibre-reinforced self-compacting concrete agree on the impact of the casting conditions on the fibre orientation and distribution, and its consequence thereof on the structural performance. A substantial number of investigations are continuously contributing to gain experience on the use of flowable FRC for different...conference paper 2016

Engen, Morten (author), Hendriks, M.A.N. (author), Øverli, Jan Arve (author), Åldstedt, Erik (author)A fully triaxial material model for concrete was implemented in a commercial finite element code. The only required input parameter was the cylinder compressive strength. The material model was suitable for non-linear finite element analyses of large concrete structures. The importance of including a crack closure algorithm was demonstrated on a...conference paper 2016

(author), Jensen, Jesper Rindom (author)Multi-microphone noise reduction algorithms in binaural hearing aids which cooperate through a wireless link have the potential to become of great importance in future hearing aid systems. However, limited transmission capacity of such devices necessitates the data compression of signals transmitted from one hearing aid to the contralateral one....conference paper 2016

(author)Applying persuasive games in mental healthcare contexts, especially using game-elements to support and redesign therapy, is a relatively new concept. In the youth addiction care context, patients often have comorbidities, causing a lot of differences between them. Besides this, therapists apply the therapy protocol in a specific personal way,...conference paper 2015

Esposito, R. (author), Hendriks, M.A.N. (author)Structures affected by Alkali-Silica Reaction (ASR) include large massive concrete dams and bridges, which are considered essential for the infrastructure system, and not easily replaceable. The main feature of this reaction is the creation of a hydrophobic expansive gel which causes internal damage in the concrete. This damage is strongly...conference paper 2015

Engen, M. (author), Hendriks, M.A.N. (author), Overli, J.A. (author), Aldstedt, E. (author)Due to practical and economic reasons the design of complex concrete structures is often based on linear FEA with rather large elements. The inelastic behavior of reinforced concrete can lead to significant load redistributions which can only be predicted using non-linear FEA (NLFEA). This work aims at developing a method for performing large...conference paper 2014

To gain insight into which game experiences can be evolved by the game, designers have been using PLEX cards in the user input phase or in the product evaluation phase of the design process. However, to our...conference paper 2014
