Meet- and join-irreducibility of additive hereditary properties of graphs
Authors: Amelie J. Berger, Izak Broere, Samuel J. T. Moagi
Venue: Discrete Mathematics (2002)

An additive hereditary property of graphs is any class of simple graphs which is closed under unions, subgraphs and isomorphisms. The set of all such properties is a lattice with set inclusion as the partial ordering. We study the elements of this lattice which are meet- join- and doubly-irreducible. The significance of these elements for the lattice of ideals of this lattice is discussed.
A Nonlinear Control Problem with Several Goal Sets
Authors: Yu. I. Berdyshev
Venue: Cybernetics and Systems Analysis (2002)

A problem is considered on detour of a manifold group moving in a geometrical coordinate space, performed by a nonlinear controlled object in a prescribed order. The quality of the process is evaluated by a sum of terminal criteria calculated on these manifolds. The necessary optimality conditions for the control of the nonlinear object and the moments of rendezvous in the form of Pontryagin maximum principle are obtained without time decomposition.
Periodic graphs and connectivity of the rational digital hyperplanes
Authors: Yan Gérard
Venue: Theoretical Computer Science (2002)

Given a digital hyperplane of Zn defined by a double-inequality hi=1naixi<h+, we want to determine whether it is connected. The problem consists of computing the connectivity of a graph whose set of vertices is not finite. The classical algorithms of labelling are not deterministic in this framework but we can think of using the properties of the digital hyperplanes and in particular their periodicity to provide a deterministic method. It leads to introduce a special kind of graphs that we call periodic and whose properties allow to compute connective components of infinite size. It provides a deterministic algorithm determining whether a given rational digital hyperplane is connecte
Complete folding of Han ideographs in internationalized domain names
Authors: Pei-Chi Wu
Venue: Computer Standards Interfaces (2002)

Discussion in the working group of Internationalized Domain Name (IDN) has raised the issue of Han folding: folding Han ideographs that are treated to be equivalent during domain name comparison. This paper addresses the complete folding of Han ideographs in IDN. Firstly, the folding is locale-independent: Han ideographs that are treated to be equivalent in one country can be folded with other equivalent ideographs in another country. Secondly, the folding is complete: all well-accepted equivalent relations in any country are included in the folding. We address and analyze issues such as the side effect and ambiguity in Han folding.
Space Complexity in Propositional Calculus
Authors: Michael Alekhnovich, Eli Ben-Sasson, Alexander A. Razborov, Avi Wigderson
Venue: SIAM Journal on Computing (2002)

We study space complexity in the framework of propositional proofs. We consider a natural model analogous to Turing machines with a read-only input tape and such popular propositional proof systems as resolution, polynomial calculus, and Frege systems. We propose two different space measures, corresponding to the maximal number of bits, and clauses/monomials that need to be kept in the memory simultaneously. We prove a number of lower and upper bounds in these models, as well as some structural results concerning the clause space for resolution and Frege systems.

Coercion as homomorphism: type inference in a system with subtyping and overloading
Authors: Alex Shafarenko
Venue: Proceedings of the 4th ACM SIGPLAN international conference on Principles and practice of declarative programming (2002)

A type system with atomic subtyping and a special form of operator overloading, which we call offset-homomorphism is proposed. A set of operator overloadings is said to be offset-homo-morphic when for each pair of overloadings the coercion function realises a homomorphism of types and at the same time certain conditions on the operator type signature are satisfied. We demonstrate that offset-homomorphic overloading has sufficient power for supporting a comprehensive set of array operations in a declarative language. The problem of inferring the least types in our type system is proven to be equivalent to the shortest path problem for weighted, directed graphs with non-negative cycle weights, which has a computationally efficient solution.
A New Merit Function For Nonlinear Complementarity Problems And A Related Algorithm
Authors: Francisco Facchinei, João Soares
Venue: SIAM Journal on Optimization (1997)

We investigate the properties of a new merit function which allows us to reduce a nonlinear complementarity problem to an unconstrained global minimization one. Assuming that the complementarity problem is defined by a $P_0$-function, we prove that every stationary point of the unconstrained problem is a global solution; furthermore, if the complementarity problem is defined by a uniform $P$-function, the level sets of the merit function are bounded. The properties of the new merit function are compared with those of Mangasarian--Solodov's implicit Lagrangian and Fukushima's regularized gap function. We also introduce a new simple active-set local method for the solution of complementarity problems and show how this local algorithm can be made globally convergent by using the new merit function.
A New Nonparametric Pairwise Clustering Algorithm Based on Iterative Estimation of Distance Profiles
Authors: Shlomo Dubnov, Ran El-Yaniv, Yoram Gdalyahu, Elad Schneidman, Naftali Tishby, Golan Yona
Venue: Machine Learning (2002)

We present a novel pairwise clustering method. Given a proximity matrix of pairwise relations (i.e. pairwise similarity or dissimilarity estimates) between data points, our algorithm extracts the two most prominent clusters in the data set. The algorithm, which is completely nonparametric, iteratively employs a two-step transformation on the proximity matrix. The first step of the transformation represents each point by its relation to all other data points, and the second step re-estimates the pairwise distances using a statistically motivated proximity measure on these representations. Using this transformation, the algorithm iteratively partitions the data points, until it finally converges to two clusters. Although the algorithm is simple and intuitive, it generates a complex dynamics of the proximity matrices. Based on this bipartition procedure we devise a hierarchical clustering algorithm, which employs the basic bipartition algorithm in a straightforward divisive manner. The hierarchical clustering algorithm copes with the model validation problem using a general cross-validation approach, which may be combined with various hierarchical clustering methods.We further present an experimental study of this algorithm. We examine some of the algorithm's properties and performance on some synthetic and &lsquo;standard&rsquo; data sets. The experiments demonstrate the robustness of the algorithm and indicate that it generates a good clustering partition even when the data is noisy or corrupted.
Computing the Effective Hamiltonian in the Majda--Souganidis Model of Turbulent Premixed Flames
Authors: Boualem Khouider, Anne Bourlioux
Venue: SIAM Journal on Numerical Analysis (2002)

Turbulence enhances the speed of propagation of a premixed flame front. According to the Majda--Souganidis model, the procedure to predict this enhancement involves computing the effective Hamiltonian in a small-scale nonlinear cell-problem. We first discuss how to transform this problem into computing the steady-state solution of a system of conservation laws whose vector solution represents the gradient of the eigenfunction associated with the effective Hamiltonian. Theoretical arguments as well as numerical evidence are presented to emphasize the importance of enforcing the constraint that the vector solution must effectively be the gradient of a scalar function. We introduce a scheme that satisfies this constraint exactly by relying on staggered grids for the gradient components. Also discussed is the issue of selecting a time integrator to achieve fast convergence to a steady state. Validation is performed by examining convergence under grid refinement and by comparison with analytical results when available.
Intentional non-photorealistic rendering
Authors: Dan Goldstein
Venue: ACM SIGGRAPH Computer Graphics (1999)

Non-photorealistic rendering (NPR) is a subject that has been generating quite a bit of interest in the computer graphics community lately. This is partly because any advance in the area is so rapidly picked up by authors who create actual content. The term NPR covers any computer-generated imagery explicitly rendered using techniques designed not to mimic physical reality. Most frequently, NPR rendering is performed by a program that takes images or three-dimensional geometry as input and creates a new output image within the bounds of a given artistic style.
COTS products characterization
Authors: Marco Torchiano, Letizia Jaccheri, Carl-Fredrik Sørensen, Alf Inge Wang
Venue: Proceedings of the 14th international conference on Software engineering and knowledge engineering (2002)

A way to learn about Commercial Off-The-Shelf (COTS) products is to define a set of characteristics or attributes and then to collect information about these attributes. In an industrial context, the attributes used to select COTS clearly depend on project specific goals. In our educational context we made an attempt to define general COTS characterization attributes. The resulting framework provides a structure, which facilitate the learning process. Our proposed attributes have several similarities with the generic evaluation attributes defined by ISO 9126. A comparison with such a standard provides a deeper insight into the problem of characterizing COTS products.
Self-similarity based texture editing
Authors: Stephen Brooks, Neil Dodgson
Venue: Proceedings of the 29th annual conference on Computer graphics and interactive techniques (2002)

We present a simple method of interactive texture editing that utilizes self-similarity to replicate intended operations globally over an image. Inspired by the recent successes of hierarchical approaches to texture synthesis, this method also uses multi-scale neighborhoods to assess the similarity of pixels within a texture. However, neighborhood matching is not employed to generate new instances of a texture. We instead locate similar neighborhoods for the purpose of replicating editing operations on the original texture itself, thereby creating a fundamentally new texture. This general approach is applied to texture painting, cloning and warping. These global operations are performed interactively, most often directed with just a single mouse movement.

This unique resource not only details ATM signaling but also discusses why, when, and how to use each signaling feature. It covers UNI 3.1, UNI 4.0, and P-NNI signaling, as well as point-to-point and point-to-multipoint signaling. In addition, it provides detailed coverage of ABR traffic signaling and negotiation. The book is an important reference for developers, systems designers, researchers, graduate students, users, and others who need to keep up-to-date with recent advances in order to understand and/or implement current standards in signaling.
Optimal Buy-and-Hold Strategies for Financial Markets with Bounded Daily Returns
Authors: Gen-Huey Chen, Ming-Yang Kao, Yuh-Dauh Lyuu, Hsing-Kuo Wong
Venue: SIAM Journal on Computing (2002)

In the context of investment analysis, we formulate an abstract online computing problem called a planning game and develop general tools for solving such a game. We then use the tools to investigate a practical buy-and-hold trading problem faced by long-term investors in stocks. We obtain the unique optimal static online algorithm for the problem and determine its exact competitive ratio. We also compare this algorithm with the popular dollar averaging strategy using actual market data.
Catadioptric Stereo Using Planar Mirrors
Authors: Joshua Gluckman, Shree K. Nayar
Venue: International Journal of Computer Vision (2001)

By using mirror reflections of a scene, stereo images can be captured with a single camera (catadioptric stereo). In addition to simplifying data acquisition single camera stereo provides both geometric and radiometric advantages over traditional two camera stereo. In this paper, we discuss the geometry and calibration of catadioptric stereo with two planar mirrors. In particular, we will show that the relative orientation of a catadioptric stereo rig is restricted to the class of planar motions thus reducing the number of external calibration parameters from 6 to 5. Next we derive the epipolar geometry for catadioptric stereo and show that it has 6 degrees of freedom rather than 7 for traditional stereo. Furthermore, we show how focal length can be recovered from a single catadioptric image solely from a set of stereo correspondences. To test the accuracy of the calibration we present a comparison to Tsai camera calibration and we measure the quality of Euclidean reconstruction. In addition, we will describe a real-time system which demonstrates the viability of stereo with mirrors as an alternative to traditional two camera stereo.

Facing budgetary shortfalls?: ways to keep IT staffing, while saving important monies for critical use
Authors: Quentin Calder
Venue: Proceedings of the 30th annual ACM SIGUCCS conference on User services (2002)

The Help Desk staff at Valparaiso University has discovered several practices that may be of use to other organizations. First, on-call student technicians working on student problems in residence halls and computer clusters greatly reduces the strain and call volume to the Help Desk. Second, on-site student User Support Specialists for faculty and also staff on-site assistance increase call ticket closure or reassignment speeds. Regularly scheduled mandatory training sessions increase student knowledge and reduce second level intervention in service requests due to consultant error or omission. Finally, having managers on each shift gives students a feeling for workplace hierarchy and reduces their reliance on full-time staff, thereby saving staff time and crucial dollars.

E-Roadmapping: Digital Strategising for the New Economy
Authors: Stefan P. Bornheim, Oliver Ohler, Jutta Weppler
Venue:  (2001)

:This book introduces e-Roadmapping-a new tool set for executives and entrepreneurs who need to strategize in the new economy. The rapidly changing commercial environment and new focus on innovation and speed of execution means that for many organizations the old models of assessing the competitive landscape and forecasting a long-term strategy are dead. So how are company leaders to plot their future and maintain a sense of direction for their business? E-Roadmapping examines ways of dealing with this complexity and provides a tool-kit for formulating strategy with an entrepreneurial spirit. Stefan Bornheim demonstrates models of "mapping" the business landscape, pinpointing areas of competition, and planning an organization's transformation. Based on extensive in-company research and full of examples of the models in action, E-Roadmapping is a stimulating look at the sharp end of the new economy.Author Biography: Stefan P. Bornheim is Research Director and Head of Executive Coaching, the Research Institute for International Management, the University of St. Gallen, Switzerland.
