Van de Par, S. (author), Kohlrauch, A. (author), Heusdens, R. (author), Jensen, J. (author), Jensen, S.H. (author)Psychoacoustical models have been used extensively within audio coding applications over the past decades. Recently, parametric coding techniques have been applied to general audio and this has created the need for a psychoacoustical model that is specifically suited for sinusoidal modelling of audio signals. In this paper, we present a new...journal article 2005

Verhoeff, R.P. (author), Moors, E.H.M. (author), Osseweijer, P. (author)Pharmacogenomics is a quickly evolving field of research that increasingly impacts individuals and society. As some innovations in biotechnology have experienced strong public opposition during the 1990s, interaction between producers and users of these innovations may help in increasing their success in social and economic terms. However,...journal article 2008

Tang, Z. (author), Leus, G.J.T. (author)In this paper, we consider pilot-aided channel estimation for orthogonal frequency division multiplexing (OFDM) systems with a multiple-input multiple-output setup. The channel is time varying due to Doppler effects and can be approximated by an oversampled complex exponential basis expansion model. We use a best linear unbiased estimator (BLUE)...journal article 2011

Wang, Y. (author), Leus, G.J.T. (author)Low-complexity least-squares (LS) estimators based on time-of-arrival (TOA) or time-difference-of-arrival (TDOA) measurements have been developed to locate a target node with the help of anchors (nodes with known positions). They require to select a reference anchor in order to cancel nuisance parameters or relax stringent synchronization...journal article 2012

Lian, X. (author), Nikookar, H. (author), Ligthart, L.P. (author)Cognitive radio (CR) is an intelligent radio system and is able to share the spectrum with licensed users (LU). By adopting adaptive beam forming techniques, CR can reuse the spectrum with LU via directing main beams towards CR users while displaying nulls towards LU. In this article, we present a new distributed beam forming (DB) technique, and...journal article 2012

Castellanos-Gomez, A. (author), Poot, M. (author), Steele, G.A. (author), Van der Zant, H.S.J. (author), Agrait, N. (author), Rubio-Bollinger, G. (author)We fabricate freely suspended nanosheets of molybdenum disulphide (MoS2) which are characterized by quantitative optical microscopy and high-resolution friction force microscopy. We study the elastic deformation of freely suspended nanosheets of MoS2 using an atomic force microscope. The Young’s modulus and the initial pretension of the...journal article 2012

(author)We fabricate and characterize carbon-fiber tips for their use in combined scanning tunneling and force microscopy based on piezoelectric quartz tuning fork force sensors. An electrochemical fabrication procedure to etch the tips is used to yield reproducible sub-100-nm apex. We also study electron transport through singlemolecule junctions...journal article 2012

Caratelli, D. (author), Gielis, J. (author), Tavkhelidze, I. (author), Ricci, P.E. (author)The Dirichlet problem for the Laplace equation in normal-polar annuli is addressed by using a suitable Fourier-like technique. Attention is in particular focused on the wide class of domains whose boundaries are defined by the so-called ‘superformula’ introduced by Gielis. A dedicated numerical procedure based on the computer algebra system...journal article 2013

Arroyo Rodriguez, C. (author), Frisenda, R. (author), Moth-Poulsen, K. (author), Seldenthuis, J.S. (author), Bjornholm, T. (author), Van der Zant, H.S. (author)Interference effects on charge transport through an individual molecule can lead to a notable modulation and suppression on its conductance. In this letter, we report the observation of quantum interference effects occurring at room temperature in single-molecule junctions based on oligo(3)-phenylenevinylene (OPV3) derivatives, in which the...journal article 2013

(author)In this paper, the problem of training optimization for estimating a multiple-input multiple-output (MIMO) flat fading channel in the presence of spatially and temporally correlated Gaussian noise is studied in an application-oriented setup. So far, the problem of MIMO channel estimation has mostly been treated within the context of minimizing...journal article 2013

(author), Watson, I.R. (author)Melanoma is the most deadly form of skin cancer. Expression of oncogenic BRAF or NRAS, which are frequently mutated in human melanomas, promote the formation of nevi but are not sufficient for tumorigenesis. Even with germline mutated p53, these engineered melanomas present with variable onset and pathology, implicating additional somatic...journal article 2013

Pournaras, E. (author), Warnier, M. (author), Brazier, M.T. (author)Aggregation functions are used in distributed environments to make system-wide information locally available in the nodes of a network. The computation of different aggregation functions, e.g., SUMMATION, AVERAGE, MAXIMUM etc., in large-scale distributed systems is challenging and crucial for a wide range of applications. This is especially the...journal article 2013

(author)Clustering is a very important tool in data mining and is widely used in on-line services for medical, financial and social environments. The main goal in clustering is to create sets of similar objects in a data set. The data set to be used for clustering can be owned by a single entity, or in some cases, information from different databases is...journal article 2013
