Khodabandeh, A. (author), Amiri-Simkooei, A.R. (author), Sharifi, M.A. (author)The efficacy of robust M-estimators is a well-known issue when dealing with observational blunders. When the number of observations is considerably large—long time series for instance—one can take advantage of the asymptotic normality of the M-estimation and compute reasonable estimates for the unknown parameters of interest. A few leading M...journal article 2011

Chitchian, M.M. (author)The particle filter is a Bayesian estimation technique based on Monte Carlo simulations. The non-parametric nature of particle filters makes them ideal for non-linear non-Gaussian systems. This greater filtering accuracy, however, comes at the price of increased computational complexity which limits their practical use for real-time applications...master thesis 2011

Blom, R.S. (author)The process of micro-milling is a promising technology for the fabrication of micro-parts with arbitrary 3D features in a wide range of materials. However, as a result of the reduced dimensions, the susceptibility of the process for machine tool errors and vibrations is higher, having adverse effects on accuracy and surface quality of the...doctoral thesis 2011

Chitu, D.A. (author)The estimation of a velocity model is an important step in seismic imaging. To a large extend, seismic data interpretation is implicitly based on this model. Thus, the velocity model influences important conclusions such as size and shape of the reservoir and the expected volume of producible hydrocarbons. In the Common Focus Point (CFP)...doctoral thesis 2011

Ou, Q. (author)Reliable and accurate estimation of traffic states play an important role in traffic management and traffic theory development, which therefore has significant social and scientific relevance. Data for traffic estimation normally from different sources and have different types, characteristics, etc, so data fusion techniques are used. Traffic...doctoral thesis 2011

Ji, L. (author), Xu, Y. (author)In (Xu and Shu in J. Sci. Comput. 40:375–390, 2009), a local discontinuous Galerkin (LDG) method for the surface diffusion of graphs was developed and a rigorous proof for its energy stability was given. Numerical simulation results showed the optimal order of accuracy. In this subsequent paper, we concentrate on analyzing a priori error...journal article 2011

Moerland, E. (author)The design of complex aircraft elements such as high-lift devices has large influence on the performance of modern transport airplanes. At the cost of increased wing weight, these devices are included in the wing to ensure safe takeoff and landing. In order to meet sustainability challenges on future air transportation systems, high-lift devices...master thesis 2011

Witte, B.I. (author)Statistics deals with answering questions based on collected data. In medical applications, the quantity of interest can often not be observed directly. They are censored. It is a challenge to answer the question as precisely as possible based on the incomplete data. The quantity of interest can be censored in many different ways. In HIV vaccine...doctoral thesis 2011

Van Dalen, K.N. (author)The characterization of porous materials (e.g., sandstone) is very important for geotechnical and reservoir engineers. For this purpose, often use is made of acoustic waves that are sent through the medium. The desired material parameters can then be estimated from the measured signals. However, often only the velocity or the attenuation of the...doctoral thesis 2011

Amiri-Simkooei, A.R. (author), Asgari, J. (author)In an attempt to model regular variations of the ionosphere, the least-squares harmonic estimation is applied to the time series of the total electron contents (TEC) provided by the JPL analysis center. Multivariate and modulated harmonic estimation spectra are introduced and estimated for the series to detect the regular and modulated dominant...journal article 2011

Van Buuren, P.J. (author)This thesis studies cost estimation and investment decisions under cost uncertainty of large construction projects. The combination of these two topics intends to satisfy the Master’s theses of Civil Engineering at the Delft University of Technology and Quantitative Finance (Econometrics) at the Erasmus University Rotterdam. The first part...master thesis 2011

Daamen, W. (author), Hoogendoorn, S.P. (author)In this paper, we show how the capacity of evacuation doors is affected by the evacuation door width, population composition, the presence of an open door and evacuation conditions. For this, laboratory experiments have been performed. Varying door opening widths showed that only the experiment with the widest door opening (275 cm) resulted in a...journal article 2010

(author)The Polarization-Based Collimated Beam Combiner efficiently produces pairwise interference between beams from multiple telescopes. An important feature is achieving ”Photometric Symmetry” whereby interference measurements have no first-order sensitivity to wavefront perturbations (or photometric variations following spatial filtering) which...conference paper 2010

Van Hinsbergen, C.P.Y. (author)This thesis deals with the optimal use of existing models that predict certain phenomena of the road traffic system. Such models are extensively used in Advanced Traffic Information Systems (ATIS), Dynamic Traffic Management (DTM) or Model Predictive Control (MPC) approaches in order to improve the traffic system. As road traffic is the result...doctoral thesis 2010

Maessen, D.C. (author), Gill, E.K.A. (author)This paper presents an investigation into the relative state estimation and observability for two formation flying satellites using two different relative navigation sensor sets. The first set consists out of a transmitter antenna on one satellite and a single receiver antenna on the other satellite to measure the inter-satellite range using a...conference paper 2010

Zhou, J. (author)Nowadays, wireless networks are used in most of the applications with radio technologies being used in all kinds of wireless networks. In all wireless links, the transmitted packets can be lost. How to identify the quality of a certain wireless link and achieve the best delivery performance over a certain wireless network is an open issue. In...doctoral thesis 2010

Van den Haak, W.P. (author)Dutch freeways suffer from severe congestion during rush hours or incidents. Research shows that 64% of congested traffic during rush hour consists of commuter traffic [30]. A traffic congestion increases travel time, resulting in a delay for travelers. Reliable travel time predictions are essential for Dynamic Routing, in which travelers can be...master thesis 2010

Sewlal, W. (author)Bij lineaire regressie geldt in het algemeen, dat het aantal metingen (n) groter is dan het aantal parameters (p). In praktische situaties kan het echter voorkomen, dat het aantal metingen veel kleiner is dan het aantal parameters. De kleinste kwadratenschatter kan in dat geval niet gebruikt worden om de parametervector te schatten, er is geen...bachelor thesis 2010

Borchert, S. (author)The main focus of video encoding in the past twenty years has been on video broadcasting. A video is captured and encoded by professional equipment and then watched on varying consumer devices. Consequently, the focus was to increase the quality and to keep down the decoder complexity. In more recent years we observe a shift in user behavior,...doctoral thesis 2010
