Gkorou, D. (author)In online communities, users frequently interact with strangers in order to buy and sell products, watch videos, educating themselves, and playing games. Establishing trust among strangers is essential for the functionality of these communities but challenging, as well. Online reputation systems effectively establish trust among strangers by...doctoral thesis 2014

Ma, L. (author), Naud, B. (author), Roekaerts, D.J.E.M. (author)MILD Combustion, also known as flameless combustion, is attracting wide scientific interest due to its potential of high efficiency and low NOx emission. This paper focuses on the numerical modeling of one of the ethanol spray flame cases from the Delft Spray-in-Hot-Coflow (DSHC) burner, which has been used to study MILD oxidation of liquid...conference paper 2014

Yu, Q. (author), Wang, Y. (author), Gao, J. (author), Gao, S. (author), Flemming, B. (author)Traditionally, vertical circulation (induced by gravity circulation and tidal straining), tidal pumping, and resuspension are suggested as the major processes for the formation and maintenance of the estuarine turbidity maximum (ETM). Due to strong mixing, tidal pumping is considered as the dominating process in macrotidal estuaries. To analyze...journal article 2014

Sheikh, A.H. (author)The Helmholtz equation is the simplest possible model for the wave propagation. Perhaps this is the reason, despite denying traditional iterative methods like Krylov sub-space methods, Multigrids, etcetera, numerical solution of the Helmholtz equation has been an interesting and abundant problem to researchers since years. The work in this...doctoral thesis 2014

Djukic, T. (author)Dynamic origin-destination (OD) demand is important input to many simulation models applied within dynamic traffic management systems (DTMS) for predicting traffic states on the network. The inability to provide high-quality dynamic OD demand estimates makes prediction with simulation models simply impossible, irrespective of how well these...doctoral thesis 2014

Wang, C. (author), Hindriks, K.V. (author), Babuska, R. (author)Learning object affordances and manipulation skills is essential for developing cognitive service robots. We propose an active affordance learning approach in continuous state and action spaces without manual discretization of states or exploratory motor primitives. During exploration in the action space, the robot learns a forward model to...conference paper 2014

Calvillo Cortés, D.A. (author)The main objectives of this thesis are to improve the energy efficiency and physical form-factor of high-power amplifiers in base station applications. As such, the focus of this dissertation is placed on the outphasing amplifier concept, which can offer high-efficiency, good linearity and excellent opportunities for system integration. With...doctoral thesis 2014

Rusak, Z. (author), Kooijman, A. (author), Song, Y. (author), Verlinden, J.C. (author), Horvath, I. (author)Motor interaction in virtual sculpting, dance trainings, and physiological rehabilitation requires close virtual proximity of users, whichmay be hindered by low resolution of images and system latency. This paper reports on the results of our investigation aiming to explore the pros and cons of using ultrahigh 4K resolution displays (4096 × 2160...journal article 2014

De Pauw, I.C. (author), Kandachar, P.V. (author), Karana, E. (author)In the field of sustainable product development, a new perspective for approaching sustainability has been advocated, challenging designers and engineers to aim beyond ‘reducing unsustainability’. Several design strategies – including Biomimicry and Cradle to Cradle – have been suggested for developing truly sustainable, or ‘beneficial’,...journal article 2014

Qu, B. (author), Li, Q. (author), Havlin, S. (author), Stanley, E. (author), Wang, H. (author)Dynamic social opinion models have been widely studied on undirected networks, and most of them are based on spin interaction models that produce a consensus. In reality, however, many networks such as Twitter and the World Wide Web are directed and are composed of both unidirectional and bidirectional links. Moreover, from choosing a coffee...journal article 2014

Bakker, C.A. (author), Kuijer, L. (author)Mobile devices like smart phones, tablet computers and ultraportable laptops are experiencing rapid worldwide market growth and have relatively short lifespans. Recently, embedded (non-removable) batteries were introduced that cannot be replaced by consumers. This study traces the environmental and social consequences of the introduction of...conference paper 2014

Jourquin, B. (author), Tavasszy, L.A. (author), Duan, L. (author)Elasticities for freight transport in the context of mode choice are hardly available for markets in which intermodal container transport competes with truck only transport. These elasticities are expected to be different, however, from values found in the literature for traditional freight transport, as trucking is a complement to rail or...journal article 2014

Shen, K. (author)Nanostructured materials are featured by providing a variety of favourable electrical properties, as the reduced ion and electron transport paths enable significant enhancement on (de)intercalation rates and hence high power. For TiO2 anatase, nano-sizing results in a curved open cell voltage profile with a much shorter plateau region in...doctoral thesis 2014

(author)Recycling crosses the fields of resource engineering, metallurgy and materials sciences, and designers cannot be expected to master all these knowledge areas. However, designers need to have access to this knowledge in a simple and clear form, to be able to design products that allow an optimal recovery with minimum quality losses. This is...conference paper 2014

Huang, H. (author)Concrete is a brittle composite cementitious material that easily fractures under tensile loading. Microcracks can appear throughout the concrete prior to application of any load because of temperature-induced strain and autogenous and drying shrinkage. There is no doubt that these cracks provide preferential access for aggressive agents to...doctoral thesis 2014
