Zhang, J.J. (author), Stoffel, M. (author), Rastelli, A. (author), Schmidt, O.G. (author), Jovanovi?, V. (author), Nanver, L.K. (author), Bauer, G. (author)The morphological evolution of both pits and SiGe islands on patterned Si(001) substrates is investigated. With increasing Si buffer layer thickness the patterned holes transform into multifaceted pits before evolving into inverted truncated pyramids. SiGe island formation and evolution are studied by systematically varying the Ge coverage and...journal article 2007

Zhang, Y. (author), De Weerdt, M.M. (author)In many applications of the task allocation problem such as peer-topeer and grid computing, and virtual organizations, the (social or business) relations between the participating agents play an important role, and thus they should be taken into account. Furthermore, in such applications, agents providing the resources usually act self...conference paper 2007

(author)We propose an amorphous/porous molecular connection network generation algorithm for simulating the material stiffness of a low-k material (SiOC:H). Based on a given concentration of the basic building blocks, this algorithm will generate an approximate and large amorphous network. The molecular topology is obtained by distributing these blocks...journal article 2008

Zhang, Y. (author), Barth, J.E. (author), Kruit, P. (author)For multielectron beam systems with a single electron source, the outside beams need to be collimated before entering the individual microcolumns. As an alternative of the traditional multibeam source design where the broad beam from the source is collimated by a single lens, the broad beam can be first split in subbeams that are focused by a...journal article 2008

Ding, Y. (author), Zhang, J.Q. (author)Retrieve the structure of model and the motion of camera is a classical and hot topic in computer vision and photogrammetry. A lot of automatic or semiautomatic techniques have been developed to optimize the retrieving processing from accuracy, stability and reality perspectives. These techniques are variant from data source, feature selection...conference paper 2008

Van der Krogt, R.P.J. (author), De Weerdt, M.M. (author), Zhang, Y. (author)Multiagent planning methods are concerned with planning by and for a group of agents. If the agents are selfinterested, they may be tempted to lie in order to obtain an outcome that is more rewarding for them. We therefore study the multiagent planning problem from a mechanism design perspective, showing how to incentivise agents to be truthful....conference paper 2008

(author)We report a heterodyne receiver using a superconducting NbN hot electron bolometer (HEB) integrated with a tight winding spiral antenna as mixer and a distributed feedback (DFB) terahertz quantum cascade laser (QCL) operating at 3.42 THz as local oscillator. The aim is to demonstrate the readiness of both devices for the detection of OH lines at...journal article 2008

Zhang, Z. (author), Xiao, Y. (author), Yang, Y. (author), Boom, R. (author), Voncken, J.H.L. (author)Vitrification is considered to be an attractive technology for bottom ash treatment because it destroys the hazardous organics, contributes to immobilization of the heavy metals, and additionally it reduces drastically the volume. The main components of the vitrified bottom ash slag are SiO2 , CaO, Al2 O3 , Fe2 O3 , Na 2 O and MgO, and the...conference paper 2009
