Liquid Crystal Heat Transfer Measurements in a Rectangular Channel with Solid and Slit Rib
Authors: P. K. Panigrahi, A. Tariq
Venue: Journal of Visualization (2003)

An experimental investigation on the heat transfer effectiveness of solid and slit ribs mounted on the bottom surface of a rectangular channel has been carried out at Reynolds numbers of 13400, 22600, 32100 and 40800. The rib height to hydraulic diameter ratio (e/D_h) set during experiment is equal to 0.0624. The surface Nusselt number results from transient liquid crystal thermography are presented. The heat transfer enhancement performance analysis has been carried out using entropy generation principle. The slit rib is superior to solid rib from both heat transfer augmentation and pressure penalty point of view. The performance of the slit rib is a function of the open area ratio (&beta;) and the location of the slit (b) from the bottom test surface. The optimum open area ratio is 20% and the slit located symmetrically from the top and bottom surface of the rib is the optimum location of the slit. The heat transfer augmentation of the slit rib (&beta; = 20%) is 61% in comparison to 40% for the solid rib at Re = 32100 and the pressure penalty for the slit rib is 7% lower than the solid rib. The entropy generation for the slit rib is 33% less than that of the solid rib.
Jackknife estimators for reducing bias in asset allocation
Authors: Amit Partani, David P. Morton, Ivilina Popova
Venue: Proceedings of the 38th conference on Winter simulation (2006)

We use jackknife-based estimators to reduce bias when estimating the optimal value of a stochastic program. Our discussion focuses on an asset allocation model with a power utility function. As we will describe, estimating the optimal value of such a problem plays a key role in establishing the quality of a candidate solution, and reducing bias improves our ability to do so efficiently. We develop a jackknife estimator that is adaptive in that it does not assume the order of the bias is known a priori.
RBF-based neurodynamic nearest neighbor classification in real pattern space
Authors: Mehmet K. Muezzinoglu, Jacek M. Zurada
Venue: Pattern Recognition (2006)

Superposition of radial basis functions centered at given prototype patterns constitutes one of the most suitable energy forms for gradient systems that perform nearest neighbor classification with real-valued static prototypes. It is shown in this paper that a continuous-time dynamical neural network model, employing a radial basis function and a sigmoid multi-layer perceptron sub-networks, is capable of maximizing such an energy form locally, thus performing almost perfectly nearest neighbor classification, when initiated by a distorted pattern. The proposed design scheme allows for explicit representation of prototype patterns as network parameters, as well as augmenting additional or forgetting existing memory patterns. The dynamical classification scheme implemented by the network eliminates all comparisons, which are the vital steps of the conventional nearest neighbor classification process. The performance of the proposed network model is demonstrated on binary and gray-scale image reconstruction applications.

Energetic performance of service-oriented multi-radio networks: issues and perspectives
Authors: Mauro Caporuscio, Damien Charlet, Valerie Issarny, Alfredo Navarra
Venue: Proceedings of the 6th international workshop on Software and performance (2007)

Wireless devices now hold multiple radio interfaces, allowing to switch from one network to another according to required connectivity and related quality. Still, the selection of the best radio interface for a specific connection is under the responsibility of the end-user in most cases. Integrated multi-radio network management so as to improve the overall performance of the network(s) up to the software application layer, has led to a number of research efforts over the last few years. However, several challenges remain due to the inherent complexity of the problem. This paper specifically concentrates on the comprehensive analysis of energy-efficient multi-radio networking for pervasive computing. Building upon the service oriented architectural style, we consider pervasive networks of software services, which are deployed on the various networked nodes. The issue is then to optimize the energetic performance of the pervasive network through careful selection of the radio link over which service access should be realized for each such access. By considering the most common wireless interfaces in use today (Bluetooth, WiFi and GPRS), we introduce a formal model of service-oriented multi-radio networks. The proposed model enables characterizing the optimal network configuration in terms of energetic performance, which is shown to be a NP-hard problem and thus requires adequate approximation.
Sure Success Partial Search
Authors: Byung-Soo Choi, Thomas A. Walker, Samuel L. Braunstein
Venue: Quantum Information Processing (2007)

Partial search has been proposed recently for finding the target block containing a target element with fewer queries than the full Grover search algorithm which can locate the target precisely. Since such partial searches will likely be used as subroutines for larger algorithms their success rate is important. We propose a partial search algorithm which achieves success with unit probability.
On the combinatorial invariance of Kazhdan-Lusztig polynomials
Authors: Federico Incitti
Venue: Journal of Combinatorial Theory Series A (2006)

In this paper, we solve the conjecture about the combinatorial invariance of Kazhdan-Lusztig polynomials for the first open cases, showing that it is true for intervals of length 5 and 6 in the symmetric group. We also obtain explicit formulas for the R-polynomials and for the Kazhdan-Lusztig polynomials associated with any interval of length 5 in any Coxeter group, showing in particular what they look like in the symmetric group.
Affine invariant comparison of point-sets using convex hulls and hausdorff distances
Authors: C. Gope, N. Kehtarnavaz
Venue: Pattern Recognition (2007)

Many object recognition or identification applications involve comparing features associated with point-sets. This paper presents an affine invariant point-set matching technique which measures the similarity between two point-sets by embedding them into an affine invariant feature space. The developed technique assumes no a priori knowledge of reference points, as is the case in many identification problems. Reference points of a point-set are obtained based on its convex hull. An enhanced version of the Modified Hausdorff Distance is also introduced and used in the feature space for comparing two point-sets. It should be noted that the technique does not attempt to obtain correspondences between the point-sets. The introduced technique is applied to two real databases and its performance is found favorable as compared to three other affine invariant matching techniques.
Foundations of incremental aspect model-checking
Authors: Shriram Krishnamurthi, Kathi Fisler
Venue: ACM Transactions on Software Engineering and Methodology (TOSEM) (2007)

Programs are increasingly organized around features, which are encapsulated using aspects and other linguistic mechanisms. Despite their growing popularity amongst developers, there is a dearth of techniques for computer-aided verification of programs that employ these mechanisms. We present the theoretical underpinnings for applying model checking to programs (expressed as state machines) written using these mechanisms. The analysis is incremental, examining only components that change rather than verifying the entire system every time one part of it changes. Our technique assumes that the set of pointcut designators is known statically, but the actual advice can vary. It handles both static and dynamic pointcut designators. We present the algorithm, prove it sound, and address several subtleties that arise, including cascading advice application and problems of circular reasoning.

Inverse Scale Spaces for Nonlinear Regularization
Authors: Johan Lie, Jan M. Nordbotten
Venue: Journal of Mathematical Imaging and Vision (2007)

Error minimization of global functionals provides a natural setting for analyzing image processing and regularization. This approach leads to scale spaces, which in the continuous formulation are the solution of nonlinear partial differential equations. In this work we derive properties for a class of inverse scale space methods. The main contribution of this paper is the development of a proof that the methods considered are convergent for convex regularization operators. The proof is based on energy methods and the Bregman distance. Further, estimates for convergence toward a clean image with noisy forcing data is provided in terms of both the L 2 norm and Bregman distances. This leads to natural estimates of optimal stopping scale for the inverse scale space method. These analytical results are discussed in the context of a numerical example.
Using copulas in risk analysis
Authors: Dalton F. Andrade, Pedro A. Barbetta, Paulo J. de Freitas Filho, Ney A. de Mello Zunino, Carlos Magno C. Jacinto
Venue: Proceedings of the 38th conference on Winter simulation (2006)

Nearly every well installation process nowadays relies on some sort of risk assessment study, given the high costs involved. Those studies focus mostly on estimating the total time required by the well drilling and completion operations, as a way to predict the final costs. Among the different techniques employed, the Monte Carlo simulation currently stands out as the preferred method. One relevant aspect which is frequently left out from simulation models is the dependence relationship among the processes under consideration. That omission can have a serious impact on the results of risk assessment and, consequently, on the conclusions drawn from them. In general, practitioners do not incorporate the dependence information because that is not always an easy task. This paper intends to show how Copula functions may be used as a tool to build correlation-aware Monte Carlo simulation models.

Venue:  (2004)

If you're ready for an Elements 3 book that breaks all the rules, this is it, because it does something for digital photographers that's never been done before--it cuts through the bull and shows you exactly "how to do it." It tells you, flat-out, which settings to use, when to use them, and why.This book is not a bunch of theory; it doesn't challenge you to come up with your own settings or figure things out on your own. It gives you the same settings used by some of the top digital pros, settings you can use today to get professional results you've always dreamed of.Plus, since this book is designed for photographers, it doesn't waste your time talking about how to frame a shot, setting your exposure, etc. and there's no talk which camera or printer to buy. It's all Elements, step-by-step, cover-to-cover in the only book of its kind, and you're gonna love it!Besides learning the inside tips and the tricks of the trade for correcting, editing, sharpening, retouching, and presenting your photos like a pro. You'll learn how to unlock the power of all the new Elements 3 features, including how to manage your photos using the new Organizer, how to use the new "pro tools" like the Healing Brush and the Shadow/Highlight controls, and how to master the new "Creation" section to take your photos to an entirely new level. Plus, you'll see it all step-by-step, in plain English, and you'll be absolutely amazed at how easy and effective these techniques are, once you know the secrets.You'll learn: The secrets of how the pros retouch portraits How to incorporate the amazing new features of Elements 3 into your work today!

Dealing with common digital camera image problems, including removing noise and avoiding halos When to use Quick Fix, and when to do to it yourself (using our step-by-step methods). The most-requested photographic special effects and much more! But besides all that, this book has a "secret weapon" that makes it the most important, most useful Elements book yet. The reason is this--although Elements 3 offers some digital photography features Photoshop CS doesn't offer, there are plenty of features that Photoshop CS has, that Elements 3 still doesn't have (things like Layer Masking, Channel Mixer, etc.). But in this book, you'll learn some slick workarounds, cheats, and some fairly ingenious ways to replicate many of those Photoshop features from right within Elements. There's never been a book like it, and if you're a digital photographer using Photoshop Elements 3, this is the book you've been waiting for.
Motivations of contributors to Wikipedia
Authors: Stacey Kuznetsov
Venue: ACM SIGCAS Computers and Society (2006)

This paper aims to explain why people are motivated to contribute to the Wikipedia project. A comprehensive analysis of the motivations of Wikipedians is conducted using the iterative methodology developed by Batya Friedman and Peter Kahn in Value Sensitive Design and Information Systems and co-developed by Nissenbaum and Friedman in Bias in Computer Systems. The Value Sensitive Design (VSD) approach consists of three stages: Empirical Investigation, Conceptual Investigation, and Technical Investigation. During the empirical phase, motivations of the contributors to Wikipedia are identified through analysis of data from two published surveys and a pilot survey conducted at New York University. The underlying values behind these motivations are then defined in the conceptual phase of the study. Finally, a technical investigation is conducted in order to determine how features of the Wiki technology support and facilitate these values.

Stochastic models of decisions about motion direction: behavior and physiology
Authors: Jochen Ditterich
Venue: Neural Networks (2006)

Roitman and Shadlen [Roitman J. D., & Shadlen M. N. (2002). Response of neurons in the lateral intraparietal area during a combined visual discrimination reaction time task. Journal of Neuroscience, 22, 9475-9489] have published a non-human primate study on visual decision making. They collected both behavioral and neurophysiological data and provided evidence that the data are qualitatively consistent with a mechanism based on accumulating sensory evidence up to a decision threshold. I have previously demonstrated that a time-variant diffusion model can account quite well quantitatively for both the behavioral and the neural data. In this manuscript I discuss how well the data constrains different components and parameters of the computational process. I also discuss the biological plausibility of the model parameters. I will demonstrate that a relatively large class of models, both with and without temporal integration and both stationary and time-variant could account for the behavioral data. Both the single cell recordings from the parietal cortex and previously published data from the extrastriate visual cortex provide additional constraints. Overall, the data favor a diffusion model with time-variant gain and leaky integrators. The integration time constant, however, turns out not to be well-constrained by the data.
Adaptive mesh refinement for coupled elliptic-hyperbolic systems
Authors: Frans Pretorius, Matthew W. Choptuik
Venue: Journal of Computational Physics (2006)

We present a modification to the Berger and Oliger adaptive mesh refinement algorithm designed to solve systems of coupled, non-linear, hyperbolic and elliptic partial differential equations. Such systems typically arise during constrained evolution of the field equations of general relativity. The novel aspect of this algorithm is a technique of "extrapolation and delayed solution" used to deal with the non-local nature of the solution of the elliptic equations, driven by dynamical sources, within the usual Berger and Oliger time-stepping framework. We show empirical results demonstrating the effectiveness of this technique in axisymmetric gravitational collapse simulations, and further demonstrate that the solution time scales approximately linearly with problem size. We also describe several other details of the code, including truncation error estimation using a self-shadow hierarchy, and the refinement-boundary interpolation operators that are used to help suppress spurious high-frequency solution components ("noise").
