Tang, X. (author), Bassir, D.H. (author), Zhang, W. (author)In this work, we explore simultaneous designs of materials selection and structural optimization. As the material selection turns out to be a discrete process that finds the optimal distribution of materials over the design domain, it cannot be performed with common gradient-based optimization methods. In this paper, material selection is...journal article 2010

Chen, X. (author), Yuan, C.A. (author), Wong, K.Y. (author), Zhang, G.Q. (author)Molecular dynamics (MD) and molecular mechanical (MM) analysis are carried out to provide reliable and accurate model for emeraldine base polyaniline. This study validate the forcefields and model with the physical and mechanical properties of the polyaniline. The temperature effects on non-bond energy, potential energy and solubility parameter...journal article 2010

Zhang, X. (author), Stoter, J.E. (author), Ai, T. (author), Kraak, M.J. (author)Automated evaluation of generalization output relies to a large extent on that requirements (e.g. specifications, constraints) being formalized in machine-readable formats. Previous studies suggest that the formalization and automated evaluation are relatively easier for legibility constraints (improve the readability of maps) than for...conference paper 2010

Brück, E.H. (author), Trung, N.T. (author), Zhang, L. (author), Caron, L. (author), Buschow, K.H.J. (author)The MnCoGe alloy can crystallize in either the hexagonal Ni2In- or the orthorhombic TiNiSi-type of structure. In both phases MnCoGe behaves like a typical ferromagnet with a second-order magnetic phase transition. For MnCoGeBx with B on interstitial positions, we discover a giant magnetocaloric effect associated with a single first-order...journal article 2010

Trung, N.T. (author), Biharie, V. (author), Zhang, L. (author), Caron, L. (author), Buschow, K.H.J. (author), Brück, E.H. (author)Substitution of some Cr for Mn atoms in MnCoGe was employed to control the magnetic and structural transitions in this alloy to coincide, leading to a single first-order magnetostructural transition from the ferromagnetic to the paramagnetic state with a giant magnetocaloric effect observed near room temperature. Further increase in the Cr...journal article 2010

Zaal, J.J.M. (author), Van Driel, W.D. (author), Zhang, G.Q. (author)This paper discusses the assembly challenges considering the design and manufacturability of a Wafer Level Thin Film Package in MEMS applications. The assembly processes are discussed. The loads associated with these processes are illustrated and evaluated. Numerical calculations are combined with experimental observations in order to estimate...journal article 2010

Zhang, Y. (author), Van der Giessen, E. (author), Nicola, L. (author)Simulations of rough surface flattening are performed on thin metal films whose roughness is created by nanoimprinting flat single crystals. The imprinting is carried out by means of a rigid template with equal flat contacts at varying spacing. The imprinted surfaces are subsequently flattened by a rigid platen, while the change of roughness and...journal article 2010

(author)We have measured the noise temperature of a single, sensitive superconducting NbN hot electron bolometer (HEB) mixer in a frequency range from 1.6 to 5.3 THz, using a setup with all the key components in vacuum. By analyzing the measured receiver noise temperature using a quantum noise (QN) model for HEB mixers, we confirm the effect of QN. The...journal article 2010

Zhang, B. (author), Grzelak, L.A. (author), Oosterlee, C.W. (author)We analyze the efficiency properties of a numerical pricing method based on Fourier-cosine expansions for early-exercise options. We focus on variants of Schwartz’ model [20] based on a mean reverting Ornstein-Uhlenbeck process [23], which is commonly used for modeling commodity prices. This process however does not possess favorable properties...report 2010

Zhang, B. (author), Oosterlee, C.W. (author)Swing options give contract holders the right to modify amounts of future delivery of certain commodities, such as electricity or gas. In this paper, we assume that these options can be exercised at any time before the end of the contract, and more than once. However, a recovery time between any two consecutive exercise dates is incorporated as...report 2010

Zhang, B. (author), Oosterlee, C.W. (author)The acceleration of an option pricing technique based on Fourier cosine expansions on the Graphics Processing Unit (GPU) is reported. European options, in particular with multiple strikes, and Bermudan options will be discussed. The influence of the number of terms in the Fourier cosine series expansion, the number of strikes, as well as the...report 2010

Zhang, L. (author)There was an explosive growth in the bioprocess industry market during the last decade. The tight control of these processes is often very critical in order to optimize the process efficiency or even achieve the right product. Capillary electrophoresis (CE) system is a good option for process monitoring and controlling, since it has already been...doctoral thesis 2009

Zhang, Y. (author), De Weerdt, M.M. (author)When information or control in a multiagent system is private to the agents, they may misreport this information or refuse to execute an agreed outcome, in order to change the resulting end state of such a system to their benefit. This may result in execution failures. When only information is private, mechanisms such as VCG use payments to...conference paper 2009
