Meeuws, R.J. (author)Heterogeneous System Development needs Hardware/Software Partitioning performed early on in the development process. In order to do this early on predictions of hardware resource usage and delay are necessary. In this thesis a Quantitative Model is presented that can make early predictions to support the partitioning process. The model is based...master thesis 2007

De Klerk, D. (author)This thesis deals with new methods, which can determine the dynamic response of a complex system identified in operation, based on the knowledge of its subsystem dynamics and excitation. In the first part of this thesis, the identification of component excitation and its transmission into the total system will be addressed. The identification of...doctoral thesis 2009

Dannenberg, F.G.W. (author)Principal component analysis (PCA) is a widespread exploratory data analysis tool. Sparse principal component analysis (SPCA) is a method that improves upon PCA by increasing the number of zeros in the loading vectors of PCA results. This makes the results more understandable and more usable. This bachelor's thesis introduces both methods, and...bachelor thesis 2010

Moore, J.K. (author), Kooijman, J.D.G. (author), Schwab, A.L. (author), Hubbard, M. (author)Recent observations of a bicyclist riding through town and on a treadmill show that the rider uses the upper body very little when performing normal maneuvers and that the bicyclist may, in fact, primarily use steering input for control. The observations also revealed that other motions such as lateral movement of the knees were used in low...journal article 2010

Eleftherakis, D. (author), Amiri-Simkooei, A. (author), Snellen, M. (author), Simons, D.G. (author)Riverbed and seafloor sediment classification using acoustic remote sensing techniques is of high interest due to their high coverage capabilities at limited cost. This contribution presents the results of riverbed sediment classification using multi-beam echo-sounder data based on an empirical method. Two data sets are considered, both taken at...journal article 2012

Feng, Q. (author)Aviation financers are interested in the current/future market value of used commercial aircraft, as this information is precious knowledge for them to support collateral position in the aircraft loan. In this paper, variables from general economy, airline industry and aviation fleet are explored to find out the factors predictive for used...master thesis 2012

Jansen, J.D. (author)This note describes the theory behind a simple Matlab program to generate ensembles of geological realizations of relatively small-scale reservoir models (permeability fields) for subsurface flow simulation. The algorithm makes use of Principal Component Analysis (PCA) to parameterize the spatial covariance of a reference image, and a Bayesian...report 2013

Roman, M. (author)By contemplating on the Eigenchair project, we ponder upon strategies and concepts of designing by using information technologies. What are the potentials of data driven design? What happens with objects when they are abstracted and reduced to a set of data? The emphasis is no longer on the creation of physical objects, but on conceiving meta...conference paper 2013

Tene, M. (author)The oil industry is at the backbone of global economy and, as natural resources are becoming scarce, there is a pressing need for efficient extraction strategies. This has led to the development of reservoir models and simulators, able to predict future field behaviour, when paired with accurate geological information. However, the data obtained...master thesis 2013

El Bouhaddani, S. (author)In modern Life Sciences, high dimensional correlated data matrices are often dealt with. Ordinary linear regression fail and PCA does not take into account the outcome variable(s). Also there might be large amount of orthogonal variation present. To deal with this, the O2PLS model (which is based on the PLS model) is derived. O2PLS is symmetric...master thesis 2014

Budiarto, E. (author)Radiotherapy is one of the methods used to treat cancer. One common approach for radiotherapy is exposing the patient to external beams of high-energy X-ray photons. Using the intensity-modulated radiation therapy (IMRT) technique, the fluence (radiation energy per unit area) of the radiation beams can be modulated to optimally shape the 3D high...doctoral thesis 2015

Lopez Lena Estrada, R. (author)In almost every field of applied science and engineering, dynamical models are widely used as a professional tool to describe in a compact format the scientific knowledge we have about the phenomena we are analyzing. Such models are widely used for the estimation, optimization, detection of failures and even for real-time control. The relevance...doctoral thesis 2016

Palma, David (author), Montessoro, Pier Luca (author), Giordano, G. (author), Blanchini, Franco (author)Most of the existing techniques for palmprint recognition rely on metrics, typically based on static functions, which evaluate the distance between a pair of features. In this paper, we propose a new technique for palmprint verification based on a dynamical system approach for principal palm lines matching. The proposed dynamic algorithm is...journal article 2017

Garufo, A. (author), Carluccio, G. (author), Freeman, Joshua R. (author), Bacon, David R. (author), Llombart, Nuria (author), Davies, Alexander G. (author), Neto, A. (author)In this paper a rigorous electromagnetic characterization of the setup for measuring the THz power radiated by pulsed photoconductive antenna is discussed. Such characterization is expressed in terms of efficiencies which quantify how much power is lost in the coupling between the various components involved in the measurement setup. The...conference paper 2017

Luo, D. (author), Cats, O. (author), van Lint, J.W.C. (author)Transit networks are complex systems in which the passenger flow dynamics are difficult to capture and understand. While there is a growing ability to monitor and record travelers' behavior in the past decade, knowledge on network-wide passenger flows, which are essentially high-dimensional multivariate data, is still limited. This paper...conference paper 2017

(author), Vandemeulebroucke, Jef (author)Image registration is an important task in medical image analysis. Whereas most methods are designed for the registration of two images (pairwise registration), there is an increasing interest in simultaneously aligning more than two images using groupwise registration. Multimodal registration in a groupwise setting remains difficult, due to...journal article 2018

van Driel, B.A. (author), van den Berg, K.J. (author), Gerretzen, J. (author), Dik, J. (author)White pigments were abundantly used in 20th century paintings, and relate to several degradation risks such as titanium white mediated photocatalytic binder degradation or zinc soap formation. Knowledge about the white pigments that were used is essential for risk assessments of 20th century collections. In this study, a representative set of...journal article 2018
