Lau, G.K. (author), Goosen, J.F.L. (author), Van Keulen, F. (author), Chu Duc, T. (author), Sarro, P.M. (author)A powerful and effective design of a polymeric thermal microactuator is presented. The design has SU-8 epoxy layers filled and bonded in a meandering silicon (Si) microstructure. The silicon microstructure reinforces the SU-8 layers by lateral restraint. It also improves the transverse thermal expansion coefficient and heat transfer for the...journal article 2007

Klein Breteler, M. (author)In het kader van het Onderzoeksprogramma Kennisleemtes Steenbekledingen is er ook aandacht gegeven aan de stabiliteit van basalt (Rudolph e.a. (2005), en de aanvullende notitie van Klein Breteler (2005)). Uit dit onderzoek is een aanbeveling gekomen omtrent het toetsen en ontwerpen van basalt. Door de gebruikersgroep van Steentoets2007 is...report 2007

Molinari, A. (author), Gutiérrez, I. (author), Hulea, I.N. (author), Russo, S. (author), Morpurgo, A.F. (author)The authors report a systematic study of the bias-dependent contact resistance in rubrene single-crystal field-effect transistors with Ni, Co, Cu, Au, and Pt electrodes. They show that the reproducibility in the values of contact resistance strongly depends on the metal, ranging from a factor of 2 for Ni to more than three orders of magnitude...journal article 2007

Chen, Y. (author)The emerging of large-scale urban (re)development projects presents a complex situation for local urban managers to deal with. They involve various local-global actors, public-private sectors and flow of finance and know-how from far beyond local city boundaries. Developing projects as such can be prolonged. In the development of Pudong New Area...doctoral thesis 2007

De Weerdt, M.M. (author), Zhang, Y. (author), Klos, T. (author)This paper proposes a new variant of the task allocation problem, where the agents are connected in a social network and tasks arrive at the agents distributed over the network. We show that the complexity of this problem remains NPhard. Moreover, it is not approximable within some factor. We develop an algorithm based on the contract-net...conference paper 2007

Verwer, S.E. (author), De Weerdt, M.M. (author), Witteveen, C. (author)We describe an algorithm for learning simple timed automata, known as real-time automata. The transitions of real-time automata can have a temporal constraint on the time of occurrence of the current symbol relative to the previous symbol. The learning algorithm is similar to the redblue fringe state-merging algorithm for the problem of learning...conference paper 2007

Steenhuisen, J.R. (author), De Weerdt, M.M. (author), Witteveen, C. (author)In crisis response, hierarchical organizations are being replaced by dynamic assemblies of autonomous agents that promise more agility. However, these autonomous agents might cause a decrease in effectiveness when individually constructed plans for moderately-coupled tasks are not jointly feasible. Existing coordination techniques can be applied...conference paper 2007

(author), Minaeva, O. (author)We have fabricated fiber-coupled superconducting single-photon detectors (SSPDs), designed for quantum-correlationtype experiments. The SSPDs are nanostructured (~100-nm wide and 4-nm thick) NbN superconducting meandering stripes, operated in the 2 to 4.2 K temperature range, and known for ultrafast and efficient detection of visible to...conference paper 2007

Toussaint, M.H. (author)In the last few years the timber gridshell has gained popularity. Recently two gridshells were constructed: the Weald and Downland gridshell in 2002 and the Savill Garden gridshell in 2006. These structures are examples from which the benefits of timber gridshells become apparent. A gridshell can display elegance and style, with its slender ribs...master thesis 2007

Swane, H.A.J. (author)This study investigates the possibility to build and operate a Tidal Power Plant (TPP) in Saemangeum in South Korea. The objective of the study is to investigate if a TPP would be technically possible and economically feasible for Saemangeum. This has resulted in a design for a Tidal Power Plant. All decisions were made taking into account...master thesis 2007

For fixed bridges a solution was found: the steel deck plate is overlayed with a concrete layer with a thickness varying between 50mm and 120mm and on top of the repair layer a new...master thesis 2007

Hindriks, C.O.H. (author)A seismic survey is conducted to acquire data which can be used to image the earth's discontuinities. On land, the near surface disturb the data severely, due to its strongly heterogeneous character. Commonly used methods use single trace methods to correct for these near surface effects based on simplified models and are known as 'statics',...doctoral thesis 2007
