Van Mieghem, P. (author), Wang, H. (author), Ge, X. (author), Tang, S. (author), Kuipers, F.A. (author)Newman’s measure for (dis)assortativity, the linear degree correlation coefficient ?D, is reformulated in terms of the total number Nk of walks in the graph with k hops. This reformulation allows us to derive a new formula from which a degree-preserving rewiring algorithm is deduced, that, in each rewiring step, either increases or decreases ?D...journal article 2010

Wang, H. (author), Kooij, R.E. (author), Van Mieghem, P. (author)We propose a class of graphs G?D(n1, n2, ..., nD+1), containing of a chain of D+1 cliques Kn1 , Kn2 , ..., KnD+1, where neighboring cliques are fully-interconnected. The class of graphs has diameter D and size N = ? 1?i?D+1ni. We prove that this class of graphs can achieve the maximal number of links, the minimum average hopcount, and more...journal article 2010

Krasnov, O.A. (author), Babur, G.P. (author), Wang, Z. (author), Ligthart, L.P. (author), Van der Zwan, F. (author)The article describes the IRCTR PARSAX radar system, the S-band high-resolution Doppler polarimetric frequency modulated continuous wave (FM-CW) radar with dual-orthogonal sounding signals, which has the possibility to measure all elements of the radar target polarization scattering matrix simultaneously, in one sweep. The performance of such...journal article 2010

(author)The cloud condensation nuclei (CCN) properties of ammonium sulfate particles mixed with organic material condensed during the hydroxyl-radical-initiated photooxidation of isoprene (C5H8) were investigated in the continuous-flow Harvard Environmental Chamber. CCN activation curves were measured for organic particle mass concentrations of 0.5 to...journal article 2010

(author)We have carried out first-principles calculations of the Compton scattering spectra to demonstrate that the filling of the hole Fermi surface in LaO1?xFxFeAs produces a distinct signature in the Fourier-transformed Compton spectrum when the momentum transfer vector lies along the [100] direction. We thus show how the critical concentration xc,...journal article 2010

Wang, J. (author), Prasad, R.V. (author), Niemegeers, I. (author)With the increase in the capacity of mobile communication devices, it is but natural to expect that these devices would work ubiquitously anywhere anytime to offer high data rate support. Recently 60 GHz frequency band has been identified as an obvious choice for the high data rate indoor communications. However, as the 60 GHz radio system...journal article 2010

Liu, D. (author), Wang, H. (author), Van Mieghem, P. (author)In recent years, many network perturbation techniques, such as topological perturbations and service perturbations, were employed to study and improve the robustness of complex networks. However, there is no general way to evaluate the network robustness. In this paper, we propose a global measure for a network, the reconstructability...journal article 2010

Wang, T. (author), Leus, G. (author), Huang, L. (author)Sensor positioning is an important task of location-aware wireless sensor networks. In most sensor positioning systems, sensors and beacons need to emit ranging signals to each other. Sensor ranging energy should be low to prolong system lifetime, but sufficiently high to fulfill prescribed accuracy requirements. This motivates us to investigate...journal article 2009

Chen, Y. (author), Wang, X. (author), Mierop, A.J. (author), Theuwissen, A.J.P. (author)This paper presents a CMOS imager sensor with pinned-photodiode 4T active pixels which use in-pixel buried-channel source followers (SFs) and optimized row selectors. The test sensor has been fabricated in a 0.18-mum CMOS process. The sensor characterization was carried out successfully, and the results show that, compared with a regular imager...journal article 2009

(author)Perovskite oxide Pb(Fe1/2Nb1/2)0.52Ti0.48O3 crystals, which were grown using a modified Bridgman method, show a high low-frequency dielectric constant response at room temperature. The Curie phase transition occurs at 523 K. The characteristic frequency of the dielectric dispersion versus the inverse of temperature obeys an Arrhenius relation,...journal article 2009

(author)We report time-dependent photocurrent and transport measurements of sub-bandgap photoexcited carriers in nitrogen-rich (type Ib), single-crystal diamond. Transient carrier dynamics are characteristic of trapping conduction with long charge storage lifetimes of ? 3?hours. By measuring the photoexcited Hall effect, we confirm that the charge...journal article 2009

Wang, C. (author), Menenti, M. (author), Stoll, M.P. (author), Feola, A. (author), Belluco, E. (author), Marani, M. (author)Light detection and ranging (LiDAR) has been shown to have a great potential in the accurate characterization of forest systems; however, its application to salt-marsh environments is challenging because the characteristic short vegetation does not give rise to detectable differences between first and last LiDAR returns. Furthermore, the lack of...journal article 2009
