On the Realization of the Wolfe Conditions in Reduced Quasi-Newton Methods for Equality Constrained Optimization
Authors: Jean Charles Gilbert
Venue: SIAM Journal on Optimization (1997)

This paper describes a reduced quasi-Newton method for solving equality constrained optimization problems. A major difficulty encountered by this type of algorithm is the design of a consistent technique for maintaining the positive definiteness of the matrices approximating the reduced Hessian of the Lagrangian. A new approach is proposed in this paper. The idea is to search for the next iterate along a piecewise linear path. The path is designed so that some generalized Wolfe conditions can be satisfied. These conditions allow the algorithm to sustain the positive definiteness of the matrices from iteration to iteration by a mechanism that has turned out to be efficient in unconstrained optimization.
Classification trees for problems with monotonicity constraints
Authors: R. Potharst, A. J. Feelders
Venue: ACM SIGKDD Explorations Newsletter (2002)

For classification problems with ordinal attributes very often the class attribute should increase with each or some of the explaining attributes. These are called classification problems with monotonicity constraints. Classical decision tree algorithms such as CART or C4.5 generally do not produce monotone trees, even if the dataset is completely monotone. This paper surveys the methods that have so far been proposed for generating decision trees that satisfy monotonicity constraints. A distinction is made between methods that work only for monotone datasets and methods that work for monotone and non-monotone datasets alike.
Experience with integrating Java with new technologies: C#, XML and web services
Authors: Judith Bishop, R. Nigel Horspool, Basil Worrall
Venue: Proceedings of the 2002 joint ACM-ISCOPE conference on Java Grande (2002)

Java programmers cannot but be aware of Microsoft's new initiative - a complete language, network environment, and a host of supporting technologies under the title of C# .NET. We highlight the advantages of C# by presenting our experiences connecting it to Java in three ways. The first is by providing a platform and language-independent XML-based API called Views for developing programmer-controlled GUIs. Views does not need C#'s resource-intensive Visual Studio development environment, and is also targeted for Unix. The second provides evidence that C# can be linked to Java at the source code level, albeit through C++ wrappers. The third is a means for retaining the useful applet feature of Java in a server-side architecture of .NET's web services. We conclude that many common shared technologies bring Java and C# together and innovative ways of using others will open up opportunities not hitherto imagined.
Stress analysis of a helical gear set with localized bearing contact
Authors: Yi-Cheng Chen, Chung-Biau Tsay
Venue: Finite Elements in Analysis and Design (2002)

This study investigates the contact stress and bending stress of a helical gear set with localized bearing contact, by means of finite element analysis (FEA). The proposed helical gear set comprises an involute pinion and a double crowned gear. Mathematical models of the complete tooth geometry of the pinion and the gear have been derived based on the theory of gearing. Accordingly, a mesh-generation program was also developed for finite element stress analysis. The gear stress distribution is investigated using the commercial FEA package, ABAQUS/Standard. Furthermore, several examples are presented to demonstrate the influences of the gear's design parameters and the contact positions on the stress distribution.
Feature based volumetric video compression for interactive playback
Authors: Bong-Soo Sohn, Chandrajit Bajaj, Vinay Siddavanahalli
Venue: Proceedings of the 2002 IEEE symposium on Volume visualization and graphics (2002)

In this paper, we describe a compression scheme for encoding time-varying isosurfaces and amorphous volumetric features (volumes within specified value ranges) in a unified way, which allows for on-line reconstruction and rendering. Since the size of even one frame in a time-varying data set is very large, transmission and on-line reconstruction are the main bottlenecks for interactive visualization of time-varying volume and surface data. To increase the run-time decompression speed and compression ratio, we decompose the volume into small blocks and encode only the significant blocks that contribute to the isosurface and volumetric features. The result shows that our compression scheme achieves high compression ratio with fast reconstruction, which is effective for client-side rendering of time-varying isosurfaces with amorphous volumetric features.

Real-world MVD's
Authors: Edward Sciore
Venue: Proceedings of the 1981 ACM SIGMOD international conference on Management of data (1981)

According to database theory, a database designer can specify any set of data dependencies, no matter how complex, to constrain a database scheme. This paper investigates how much complexity is actually needed in real-world situations. It is shown that every "natural" set of mvd's must belong to a class of mvd's called conflict-free. Conflict-free sets of mvd's have the desirable property that they allow a unique 4NF dependency preserving database scheme; moreover, non conflict-free sets have no such normalization. If a set of mvd's is not conflict-free, then the dependencies are inadequately specified; there are semantic concepts that are unrepresented in the scheme. These concepts are isolated, and it is shown that adding these concepts amounts to making the set of mvd's conflict-free.
An H1-Galerkin Mixed Finite Element Method for an Evolution Equation with a Positive-Type Memory Term
Authors: Amiya K. Pani, Graeme Fairweather
Venue: SIAM Journal on Numerical Analysis (2002)

An H1-Galerkin mixed finite element method is analyzed for a class of evolution equations with memory. When a classical mixed method is applied to such problems, it has not been possible to obtain any estimate for the flux. However, the proposed approach yields optimal order convergence without the LBB consistency condition and quasi uniformity of the finite element mesh. Compared to the results proved for one space variable, the L2 estimate of the flux is not optimal for problems in two and three space dimensions. Therefore, a modification of the method is proposed and analyzed. A maximum norm estimate is also derived in one and two space variables. A backward Euler approximation of the modified method is also analyzed.

Time Series Analysis: Forecasting and Control, 3rd edition
Authors: George Edward Pelham Box, Gwilym M. Jenkins
Venue:  (1994)

:This is a complete revision of a classic, seminal, and authoritative book that has been the model for most books on the topic written since 1970. It focuses on practical techniques throughout, rather than a rigorous mathematical treatment of the subject. It explores the building of stochastic (statistical) models for time series and their use in important areas of application forecasting, model specification, estimation, and checking, transfer function modeling of dynamic relationships, modeling the effects of intervention events, and process control. Features sections on: recently developed methods for model specification, such as canonical correlation analysis and the use of model selection criteria; results on testing for unit root nonstationarity in ARIMA processes; the state space representation of ARMA models and its use for likelihood estimation and forecasting; score test for model checking; and deterministic components and structural components in time series models and their estimation based on regression-time series model methods.
Internet Core Protocols: The Definitive Guide with Cdrom, 1st edition
Authors: Eric Hall
Venue:  (1999)

:If you've ever been responsible for a network, you know that sinking feeling: your pager has gone off at 2 a.m., the network is broken, and you can't figure out why using a dial-in connection from home. You drive into the office, dig out your protocol analyzer, and spend the next four hours trying to put things back together before the staff shows up for work. When this happens, you often find yourself looking at the low-level guts of the Internet protocols: you're deciphering individual packets, trying to figure out what is (or isn't) happening. Until now, the only real guide to the protocols has been the Internet RFCs  and they're hardly what you want to be reading late at night when your network is down. There hasn't been a good book on the fundamentals of IP networking aimed at network administrators  until now. Internet Core Protocols: The Definitive Guide contains all the information you need for low-level network debugging. It provides thorough coverage of the fundamental protocols in the TCP/IP suite: IP, TCP, UDP, ICMP, ARP (in its many variations), and IGMP. (The companion volume, Internet Application Protocols: The Definitive Guide, provides detailed information about the commonly used application protocols, including HTTP, FTP, DNS, POP3, and many others). It includes many packet captures, showing you what to look for and how to interpret all the fields. It has been brought up-to-date with the latest developments in real-world IP networking. The CD-ROM included with the book contains Shomiti's "Surveyor Lite," a packet analyzer that runs on Win32 systems, plus the original RFCs, should you need them for reference.Together, this package includes everything you need to troubleshoot your network  except coffee.

:The present book is primarily the first of its kind in the world. It contains almost all the topics connected with protection schemes. The book, which contains in all nine main chapters and an Appendix, starts with the chapter on Introduction and includes chapters on fundamental and basic theory of protection schemes, definition of various terms, different types of protective relaying schemes, generalized mathematical theory of protective relay, relay as a comparator, single input, dual input and multi-input comparator, different types and arrangement of protection schemes for various components and detailed studies of electromechanical, electronics, static and digital relaying schemes. The digital protection of synchronous machines, transformer and transmission line based both on fundamental and travelling wave phenomena are dealt with in detail. Also included in the present volume, are the related topics such as theory and design of dynamic test bench and P.C. based short circuit studies for the purpose of designing appropriate protection schemes. The present volume which contains almost all the topics of current interests in the area of protective relaying will certainly be very useful to the teachers, students and engineers working with the utilities. The present book is the result of teaching by the author the under-graduate and post-graduate level classes and supervising several doctoral and master thesis and graduate level projects in the area of power system protection at the Indian Institute of Technology, Kanpur for nearly two decades. The content of the present volume has been class tested for several years at the under-graduate and post-graduate level classes at I.I.T. Kanpur. It has also been tested in several intensive courses offered by the author under QIP and other schemes to the teachers of academic institutions and also engineers working with utilities.
Review of proof, language, and interaction: essays in honour of Robin Milner edited by Plotkin, Stirling and Tofte
Authors: Riccardo Pucella
Venue: ACM SIGACT News (2001)

The field of theoretical computer science has had a long tradition of providing wonderful edited books to honor various prominent members of the community. The idea behind such edited works is clear: celebrate the work of a particular researcher by having co-authors and colleagues write papers on subjects related to the researcher's body of work. When successful, such a project provides for a wonderful excursion through the work of a researcher, often highlighting an underlying coherence to that work.On that account, the book Proof, Language, and Interaction: Essays in the Honor of Robin Milner (edited by Plotkin, Stirling and Tofte) is a success. In no small part this is due to Milner's span of work from theory to practice. It is hard to both briefly describe Milner's contributions and give an idea of the breadth of his effort. Two major tracks of research emerge. First, after some work with John McCarthy's AI group at Stanford, he developed LCF (specifically, Edinburgh LCF), a system for computer-assisted theorem proving based on Dana Scott's idea on continuous partial functions for denotational semantics. Not only working on the implementation, Milner also worried about the semantic foundations [1]. LCF came with a programming language, Edinburgh ML, which evolved with Milner's help into standard ML, a higher-order language that introduced many features now standard in advanced programming language, features such as polymorphism and type inference [4]. His second track of research involves concurrency. He invented CCS, the calculus of communicating systems [2]. Work on the semantics of CCS went from the traditional domain-theoretic approach to a new operational view of processes equality based on the notion of bisimulation. Subsequent work by Milner led to the development of other calculi, most notably the &pi;-calculus, which included a powerful notion of mobility [3]. His later work in the area attempted to provide a unifying framework for comparing calculi, and unifying sequential and concurent computation.This range of interests is reflected in the table of contents of the book. The book splits across different subjects: semantic foundations, where we discover work aimed at understanding computation, both sequential and concurrent, programming logic, where we discover work derived from Milner's work on LCF, and aimed at understanding the role of formal mathematics, programming languages, where we discover Standard ML, and other languages based on Milner's idea about concurrent calculi, concurrency, where we discover work on Milner's early CCS approach and extensions, and mobility, where we discover work related to the &pi;-calculus.
Dot.Con: The Greatest Story Ever Sold
Authors: John Cassidy
Venue:  (2002)

:In Dot.Con, John Cassidy argues that what we have witnessed was not just a stock market bubble, but a buying frenzy that drove the prices of dot-coms to stratospheric heights that were absolutely impossible to maintain. He explains how it happened and how all involvedfund managers, stock analysts, journalistswere simply acting in their own best interests. He focuses on the role played by entrepreneurs like Jeff Bezos, venture capitalists like John Doerr, Wall Street analysts like Mary Meeker, journalists like Maria Bartiromo, and policy-makers like Alan Greenspan. In a narrative that is lively and entertaining, Cassidy reveals how millions of ordinary Americans got caught up in this mirage and confused wishful thinking with realityuntil the inevitable bust brought them to their senses.

A mixture model for the connection holding times in the video-on-demand service
Authors: Maurizio Naldi
Venue: Performance Evaluation (2002)

A fundamental traffic parameter for the design of a network supporting the Video-on-Demand service is the connection holding time. This holding time is usually characterized by its average value and, possibly, by its probability density function (pdf). In this paper, a model is proposed for this density, consisting of a mixture of Gaussian pdf's, whose parameters are estimated through the combination of the K-means algorithm and of a recursive likelihood maximization procedure. The model has been applied to a data set extracted from a video catalogue. Exponential and log-normal models have been fitted to the same data set by comparison. For all three models, the chi-square statistic and the Akaike Information Criterion result to be much lower for the mixture model than for the other two. In addition, the shape of the mixture pdf resembles more closely the multimodal characteristic of the empirical data. This results have been obtained with a mixture of limited complexity, being made up of a small number of Gaussian components (three or four).

Authors: David Mercer, Matthias Arndt
Venue:  (2001)

:The key takeaway from this book is that, despite all the recent hype, e-commerce follows most of the marketing rules that have long been established in conventional markets. What has changed is the variety and scope of new channels to market. David Mercer picks through the most important of these channels and signposts the key activities that will enable companies to successfully incorporate the best e-commerce elements of business into an effective, profitable marketing mix. What is vital is creating a synergy between the old and new ways of doing business. The topic of e-marketing is approached from the perspective of a traditional business incorporating clicks into bricks. Genuinely interactive one-to-one customer relationship management is closely examined, as well as B2B (business to business) and C2C (consumer to consumer) models. These models are set within the context of product/service decisions, pricing and promotion, e-retail, future developments and the thorny issue of how to actually make money online. Readers will emerge with an enhanced understanding of the true potential of e-marketing and a set of powerful, practical tools needed to effectively express themselves and their enterprise in this multichannel environment.
A novel methodology for robust VBR video transmission in an ATM system
Authors: A. Alheraish, D. G. Smith, J. Irvine
Venue: International Journal of Network Management (2002)

A dynamic FEC (DFEC) scheme for VBR video in ATM networks is proposed. The scheme combines the design of source encoder, error control, and the network. In the design, we will develop a methodology to vary FEC redundancy dynamically. The methodology considers the fluctuations in video source and network utilisation to adjust the FEC redundancy levels. We demonstrate the effectiveness of the proposed scheme by examining its performance with three existing schemes in terms of loss rates, throughput, and quality degradation.
