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

Fakhredin, F. (author), Bakker, C.A. (author), Geraedts, J.M.P. (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

Kulkarni, S. (author)Crystallization is an essential step in many processes in chemical industries, ranging from bulk chemicals to special products. It is a separation and purification technique that results in a solid particulate product, which is generally preferred in the pharmaceutical industry. The crystal product quality is determined by the specific crystal...doctoral thesis 2014

Negro, E. (author)Graphitic materials have attracted a great interest in the field of sustainable energy production and storage because of their excellent electrical, mechanical and chemical properties. This thesis modestly contributes to this global research by investigating new interconnected carbon nanostructures, here called Carbon Nano-Networks (CNNs). The...doctoral thesis 2014

Van der Voort, H.G. (author), De Bruijn, J.A. (author), Sidorova, Y. (author), Arnaboldi, M. (author)One major strategy to incorporate social media in the organizational structure is erecting a ‘social media hub’, a relatively independent organization within a standing organization. The standing organization with its divisions do not change, but the hub has considerable possibilities to operate independently within and in between these...conference paper 2014

Vreeswijk, J.D. (author), Rakha, H. (author), Van Berkum, E. (author), Van Arem, B. (author)In the context of route choice, inertial behaviour shows that drivers make choices that are satisfactory rather than optimal. Consequently, drivers may not necessarily alter their choice when confronted with a travel time increase on the current choice or a travel time decrease of a choice alternative. As a consequence it can be assumed that...conference paper 2014

Nasri, A. (author)Nowadays, power systems are dealing with some new challenges raised by the major changes that have been taken place since 80’s, e.g., deregulation in electricity markets, significant increase of electricity demands and more recently large-scale integration of renewable energy resources such as wind power. Therefore, system operators must make...doctoral thesis 2014

Goni Ros, B. (author), Knoop, V.L. (author), Van Arem, B. (author), Hoogendoorn, S.P. (author)Sags are freeway sections along which the gradient changes significantly from downwards to upwards. The capacity of sags is considerably lower than the capacity of normal sections. Consequently, sags are often freeway bottlenecks. Recently, several control measures have been proposed to improve traffic flow efficiency at sags. Those measures...conference paper 2014

Ozmen, N. (author)The main focus of this thesis is on modeling acoustic wavefield propagation and implementing imaging algorithms for breast cancer detection using ultrasound. As a starting point, we use an integral equation formulation, which can be used to solve both the forward and inverse problems. This thesis contains three main topics: forward modeling,...doctoral thesis 2014

Schakel, W.J. (author), Van Arem, B. (author), Van Lint, J.W.C. (author)For a recently developed in-car speed, headway and lane use advisory system, this paper investigates empirically advice validity (advice given in correct traffic circumstances), credibility (advice logical to drivers) and frequency. The system has been developed to optimize traffic flow by giving advice on a tactical scale. This scale allows...conference paper 2014

Smets, P.S.M. (author), Evers, L.G. (author)A method is presented to study the life cycle of a SSW using infrasonic ambient noise observations. The potential of infrasound is shown to provide the missing observations required by numerical weather prediction to better resolve the upper atmosphere. The 2009 major SSW is reanalyzed using the Evers and Siegmund (2009) data set. Microbarom...journal article 2014

Van der Gun, J.P.T. (author), Pel, A.J. (author), Van Arem, B. (author)There are many kinds of disasters that can severely impact the transportation system of an urbanized region. Transportation authorities therefore need to develop management strategies to adequately deal with such emergencies. In this paper, we discuss the structure of a simulation model that can be used to assess a candidate strategy. We model...conference paper 2014

Varotto, S.F. (author), Hoogendoorn, R.G. (author), Van Arem, B. (author), Hoogendoorn, S.P. (author)Automated driving potentially has a significant impact on traffic flow efficiency. Automated vehicles, which possess cooperative capabilities, are expected to reduce congestion levels for instance by increasing road capacity, by anticipating traffic conditions further downstream and also by accelerating the clearance of congestion. However, the...conference paper 2014
