Finite-difference method for incompressible Navier-Stokes equations in arbitrary orthogonal curvilinear coordinates
Authors: Nikolay Nikitin
Venue: Journal of Computational Physics (2006)

A finite-difference method for solving three-dimensional time-dependent incompressible Navier-Stokes equations in arbitrary curvilinear orthogonal coordinates is presented. The method is oriented on turbulent flow simulations and consists of a second-order central difference approximation in space and a third-order semi-implicit Runge-Kutta scheme for time advancement. Spatial discretization retains some important properties of the Navier-Stokes equations, including energy conservation by the nonlinear and pressure-gradient terms. Numerical tests cover Cartesian, cylindrical-polar, spherical, cylindrical elliptic and cylindrical bipolar coordinate systems. Both laminar and turbulent flows are considered demonstrating reasonable accuracy and stability of the method.
Semidefinite spectral clustering
Authors: Jaehwan Kim, Seungjin Choi
Venue: Pattern Recognition (2006)

Multi-way partitioning of an undirected weighted graph where pairwise similarities are assigned as edge weights, provides an important tool for data clustering, but is an NP-hard problem. Spectral relaxation is a popular way of relaxation, leading to spectral clustering where the clustering is performed by the eigen-decomposition of the (normalized) graph Laplacian. On the other hand, semidefinite relaxation, is an alternative way of relaxing a combinatorial optimization, leading to a convex optimization. In this paper we employ a semidefinite programming (SDP) approach to the graph equipartitioning for clustering, where sufficient conditions for strong duality hold. The method is referred to as semidefinite spectral clustering, where the clustering is based on the eigen-decomposition of the optimal feasible matrix computed by SDP. Numerical experiments with several data sets, demonstrate the useful behavior of our semidefinite spectral clustering, compared to existing spectral clustering methods.
An efficient sensitivity computation strategy for the evolutionary structural optimization (ESO) of continuum structures subjected to self-weight loads
Authors: Rubén Ansola, Javier Canales, José A. Tárrago
Venue: Finite Elements in Analysis and Design (2006)

This work presents a modified version of the evolutionary structural optimization procedure for topology optimization of continuum structures subjected to self-weight forces. Here we present an extension of this procedure to deal with maximum stiffness topology optimization of structures when different combinations of body forces and fixed loads are applied. Body forces depend on the density distribution over the design domain. Therefore, the value and direction of the loading are coupled to the shape of the structure and they change as the material layout of the structure is modified in the course of the optimization process. It will be shown that the traditional calculation of the sensitivity number used in the ESO procedure does not lead to the optimum solution. Therefore, it is necessary to correct the computation of the element sensitivity numbers in order to achieve the optimum design. This paper proposes an original correction factor to compute the sensitivities and enhance the convergence of the algorithm. The procedure has been implemented into a general optimization software and tested in several numerical applications and benchmark examples to illustrate and validate the approach, and satisfactorily applied to the solution of 2D, 3D and shell structures, considering self-weight load conditions. Solutions obtained with this method compare favourably with the results derived using the SIMP interpolation scheme.

Packet-level integration of fluid TCP models in real-time network simulation
Authors: Jason Liu
Venue: Proceedings of the 38th conference on Winter simulation (2006)

We present a hybrid network traffic model that combines time-stepping fluid model with discrete-event packet-oriented simulation. We propose an integration scheme allowing packet flows to interact with fluid flows within each network queue. Different from previous schemes that require physical division of the virtual network between the fluid model and packet-oriented simulation, our hybrid model allows full integration of the two paradigms making it possible to dynamically change the composition of traffic flows to allow the simulation to keep up with real time. Experiments show that our model provides a good prediction of the network behavior. More important, as we increase the proportion of packet flows, the simulation is capable of capturing more detail of the network traffic behavior at the expense of more computing time. Hence the tradeoff.

A mura detection method
Authors: Kazutaka Taniguchi, Kunio Ueta, Shoji Tatsumi
Venue: Pattern Recognition (2006)

A method to detect mura, which is defined as an irregular lightness variation on a uniformly manufactured surface, is necessary to maintain the quality of the display devices. The mura is understood as defects without a clear contour or a contrast which imparts an unpleasant sensation to viewers. We propose a method to detect mura of the display devices' components that have lower intensity than the final device with some background pattern considering the property of the human vision system.
Hold your horses: a dynamic computational role for the subthalamic nucleus in decision making
Authors: Michael J. Frank
Venue: Neural Networks (2006)

The basal ganglia (BG) coordinate decision making processes by facilitating adaptive frontal motor commands while suppressing others. In previous work, neural network simulations accounted for response selection deficits associated with BG dopamine depletion in Parkinson's disease. Novel predictions from this model have been subsequently confirmed in Parkinson patients and in healthy participants under pharmacological challenge. Nevertheless, one clear limitation of that model is in its omission of the subthalamic nucleus (STN), a key BG structure that participates in both motor and cognitive processes. The present model incorporates the STN and shows that by modulating when a response is executed, the STN reduces premature responding and therefore has substantial effects on which response is ultimately selected, particularly when there are multiple competing responses. Increased cortical response conflict leads to dynamic adjustments in response thresholds via cortico-subthalamic-pallidal pathways. The model accurately captures the dynamics of activity in various BG areas during response selection. Simulated dopamine depletion results in emergent oscillatory activity in BG structures, which has been linked with Parkinson's tremor. Finally, the model accounts for the beneficial effects of STN lesions on these oscillations, but suggests that this benefit may come at the expense of impaired decision making.

Understanding accident and emergency department performance using simulation
Authors: Murat M. Gunal, Michael Pidd
Venue: Proceedings of the 38th conference on Winter simulation (2006)

As part of a larger project examining the effect of performance targets on UK hospitals, we present a simulation of an Accident and Emergency (A&E) Department. Performance targets are an important part of the National Health Service (NHS) performance assessment regime in the UK. Pressures on A&Es force the medical staff to take actions meeting these targets with limited resources. We used simulation modelling to help understand the factors affecting this performance. We utilized real data from patient admission system of an A&E and presented some data analysis. Our particular focuses are the multitasking behaviour and experience level of medical staff, both of which affect A&E performance. This performance affects, in turn, the overall performance of the hospital of which it is part.

Effect of Signal and Noise Mutual Coupling on MIMO Channel Capacity
Authors: Snezana M. Krusevac, Rodney A. Kennedy, Predrag B. Rapajic
Venue: Wireless Personal Communications: An International Journal (2007)

In this paper we analyze the impact of mutual coupling on MIMO channel capacity, considering its effect on both signal and thermal noise. We calculate noise correlation matrix in the multi-antenna system with closely spaced antenna by applying Nyquist's thermal noise theorem. Then, we employ the noise correlation matrix in the channel capacity formula, which enables the identification of thermal noise correlation contribution on the MIMO channel capacity. In addition, we examine the variations in the mean branch signal-to-noise ratios (SNR) due to the noise correlation. Our simulation results corroborate the theoretical analysis that mean and outage MIMO channel capacity is underestimated if noise correlation due to mutual coupling effect is not accounted for.

Scaling Security of Elliptic Curves with Fast Pairing Using Efficient Endomorphisms*This work was partially presented at SCIS 2006, held in Hiroshima.
Authors: Katsuyuki Takashima
Venue: IEICE Transactions on Fundamentals of Electronics, Communications and Computer Sciences (2007)

Cryptosystems using pairing computation on elliptic curves have various applications including ID-based encryption ([9], [29], [30] etc.). Scott [33] proposed a scaling method of security by a change of the embedding degree k. On the other hand, he also presented an efficient pairing computation method on an ordinary (non-supersingular) elliptic curve over a large prime field <Fopf>p ([34]). In this paper, we present an implementation method of the pairing computation with both of the security scaling in [33] and the efficiency in [34]. First, we will investigate the mathematical nature of the set of the paremeter r (the order of cyclic group used) so as to support many k's. Then, based on it, we will suggest some modification to the algorithm of Scott in [34] to achieve flexible scalability of security level.
An estimate for multivariate interpolation II
Authors: W. R. Madych
Venue: Journal of Approximation Theory (2006)

Suppose u is a function on a domain Ω in Rn all of whose mth order distributional derivatives are in Lp (Ω) and m is sufficiently large to imply that u is continuous. If the values of u on a sufficiently dense, but not necessarily regular, grid of points are in lp we obtain an estimate of the LP(Ω) norm of u in terms of the lp norm of these values and the Lp norms of its mth order derivatives. This result is useful in obtaining error estimates for certain interpolation schemes.
A study of Gaussian mixture models of color and texture features for image classification and segmentation
Authors: Haim Permuter, Joseph Francos, Ian Jermyn
Venue: Pattern Recognition (2006)

The aims of this paper are two-fold: to define Gaussian mixture models (GMMs) of colored texture on several feature spaces and to compare the performance of these models in various classification tasks, both with each other and with other models popular in the literature. We construct GMMs over a variety of different color and texture feature spaces, with a view to the retrieval of textured color images from databases. We compare supervised classification results for different choices of color and texture features using the Vistex database, and explore the best set of features and the best GMM configuration for this task. In addition we introduce several methods for combining the 'color' and 'structure' information in order to improve the classification performances. We then apply the resulting models to the classification of texture databases and to the classification of man-made and natural areas in aerial images. We compare the GMM model with other models in the literature, and show an overall improvement in performance.
On the classification of all self-dual additive codes over GF(4) of length up to 12
Authors: Lars Eirik Danielsen, Matthew G. Parker
Venue: Journal of Combinatorial Theory Series A (2006)

We consider additive codes over GF(4) that are self-dual with respect to the Hermitian trace inner product. Such codes have a well-known interpretation as quantum codes and correspond to isotropic systems. It has also been shown that these codes can be represented as graphs, and that two codes are equivalent if and only if the corresponding graphs are equivalent with respect to local complementation and graph isomorphism. We use these facts to classify all codes of length up to 12, where previously only all codes of length up to 9 were known. We also classify all extremal Type II codes of length 14. Finally, we find that the smallest Type I and Type II codes with trivial automorphism group have length 9 and 12, respectively.

Quantifying the effect of a control point on the sign of curvature
Authors: E. I. Karousos, A. I. Ginnis, P. D. Kaklis
Venue: Computing (2007)

We present a method for computing the domain, where a control point is free to move so that the corresponding planar curve is regular and of constant sign of curvature along a subinterval of its parametric domain of definition. The approach encompasses all curve representations that adopt the control-point paradigm and is illustrated for a quintic B&#x00e9;zier curve and a B-spline curve of degree 10.
