Koutrouvelis, A. (author), Hendriks, R.C. (author), Heusdens, R. (author), Jensen, Jesper (author)In this paper, we propose a new binaural beamforming technique, which can be seen as a relaxation of the linearly constrained minimum variance (LCMV) framework. The proposed method can achieve simultaneous noise reduction and exact binaural cue preservation of the target source, similar to the binaural minimum variance distortionless response ...journal article 2017

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

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

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) in concrete is one of the most harmful deterioration processes, which leads to expansion and cracking of the material. To understand the evolution of ASR in concrete and its deteriorating impact on the material, a multiscale material model, from aggregate to concrete level, is proposed. The concrete, which at...journal article 2016

Esposito, R. (author), Anac, C. (author), Hendriks, M.A.N. (author), Copuroglu, Oguzhan (author)The alkali-silica reaction (ASR) is an important problem that has yet to be completely understood. Owing to the complexity of this<br/>phenomenon, a number of studies have been conducted to characterize its kinetics, its impact on the material, and its structural consequences.<br/>This paper focuses on the deteriorating impact of ASR on concrete...journal article 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

(author)Personalization, the involvement of stakeholders in the design process, is often applied in serious game design for health. It is expected to enhance the alignment of a game to the preferences and capacities of the end-user, thereby increasing the end-user’s motivation to interact with the game, which finally might enhance the aimed-for health...journal article 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

Esposito, R. (author), Hendriks, M.A.N. (author)Unaffected and ASR-affected concrete, experimentally, appear as substantially different materials. Since the material characterization is one of the main points of attention within a structural assessment, the deteriorating impact of ASR on concrete in terms of both expansion and degradation of the mechanical properties is studied. Both...book chapter 2015
