An Inverse Free Preconditioned Krylov Subspace Method for Symmetric Generalized Eigenvalue Problems
Authors: Gene H. Golub, Qiang Ye
Venue: SIAM Journal on Scientific Computing (2002)

In this paper, we present an inverse free Krylov subspace method for finding some extreme eigenvalues of the symmetric definite generalized eigenvalue problem $Ax = \lambda B x$. The basic method takes a form of inner-outer iterations and involves no inversion of B or any shift-and-invert matrix $A-\lambda_0 B$. A convergence analysis is presented that leads to a preconditioning scheme for accelerating convergence through some equivalent transformations of the eigenvalue problem. Numerical examples are given to illustrate the convergence properties and to demonstrate the competitiveness of the method.

Usability testing: revisiting informed consent procedures for testing internet sites
Authors: Oliver K. Burmeister
Venue: Selected papers from the second Australian Institute conference on Computer ethics (2000)

This paper explores issues of professional, ethical conduct in usability testing centering around the concept of 'informed consent'. Previous work on informed consent has been in homogeneous geographic locations. With Internet sites being developed at a prodigious rate, these procedures need to be revisited for their applicability to heterogeneous locations, in terms of culture, business practice, language and legal requirements. Some previously valued principles might now be considered discretionary, that is their applicability has situational specificity. Other principles are mandatory.

Parsek: object oriented particle in cell. implementation and performance issues
Authors: Stefano Markidis, G. Lapenta, W. B. VanderHeyden
Venue: Proceedings of the 2002 joint ACM-ISCOPE conference on Java Grande (2002)

Previous plasma simulations have used Fortran or other computer languages in which it is difficult to directly express the underlying physics. In a plasma, each particle - electron, ion, or dust - interacts with the external fields and with other particles in ways that can be readily and effectively mimicked by object oriented programming. Thus, we have used JAVA's strong object design to rewrite traditional plasma simulation codes. By using coarse grain and fine grain object design, we incorporate the power of object oriented design for programming and for making the physics clear while paying only a small cost in increased computational time. The JAVA implementation has also the advantage that changes in the underlying physical model can be easily completed swapping or adding objects without large scale revisions of the code.
The Effectiveness of Control Structure Diagrams in Source Code Comprehension Activities
Authors: Dean Hendrix, James H. Cross,  II, Saeed Maghsoodloo
Venue: IEEE Transactions on Software Engineering (2002)

Recently, the first two in a series of planned comprehension experiments were performed to measure the effect of the control structure diagram (CSD) on program comprehensibility. Upper- and lower-division computer science and software engineering students were asked to respond to questions regarding the structure and execution of one source code module of a public domain graphics library. The time taken for each response and the correctness of each response was recorded. Statistical analysis of the data collected from these two experiments revealed that the CSD was highly significant in enhancing the subjects' performance in this program comprehension task. The results of these initial experiments promise to shed light on fundamental questions regarding the effect of software visualizations on program comprehensibility.
XML Schema Essentials
Authors: Andrew Watt, R. Allen Wyke
Venue:  (2002)

:Replacing XML DTDs (Document Type Definitions) as the way in which XML documents are described and validated, XML Schema allows you to describe the structure of information in an XML document and is essential for ensuring the accuracy and security of information in B2B transactions and other XML applications. Since XML Schema defines a greater and more complex set of datatypes than XML DTDs -- such as numbers, dates, times, and currencies -- it is an invaluable tool for e-commerce applications. XML Schema also offers more flexibility than XML DTDs, with its ability to have users define datatypes for data (for example, an "address" can be further refined as a "postal address," "billing address," or "shipping address") and its ability to validate documents based on namespaces, which allows for the distinction between identical terms being used in different contexts. This hands-on guide uses extensive examples and source code to provide you with all the information you'll need to understand and use XML Schema. Beginning with an example of a simple schema, the authors provide you with the opportunity to quickly become familiar with coding structure, and offer in-depth explanations for each example. The book progresses logically through basic schema concepts and applications such as datatypes and structures, and then gradually moves to more complex examples and advanced topics such as unique element and attribute values and keys.
Incommunicado: efficient communication for isolates
Authors: Krzysztof Palacz, Jan Vitek, Grzegorz Czajkowski, Laurent Daynas
Venue: Proceedings of the 17th ACM SIGPLAN conference on Object-oriented programming, systems, languages, and applications (2002)

Executing computations in a single instance of safe language virtual machine can improve performance and overall platform scalability. It also poses various challenges. One of them is providing a fast inter-application communication mechanism. In addition to being efficient, such a mechanism should not violate any functional and non-functional properties of its environment, and should also support enforcement of application-specific security policies. This paper explores the design and implementation of a communication substrate for applications executing within a single Java virtual machine modified to enable safe and interference-free execution of isolated computations. Designing an efficient extension that does not break isolation properties and at the same time pragmatically offers an intuitive API has proven non-trivial. This paper demonstrates a set of techniques that lead to at least an eight-fold performance improvement over the in-process inter-application communication using standard mechanisms offered by the Java platform.
Dual-Bounded Generating Problems: All Minimal Integer Solutions for a Monotone System of Linear Inequalities
Authors: E. Boros, K. Elbassioni, V. Gurvich, L. Khachiyan, K. Makino
Venue: SIAM Journal on Computing (2002)

We consider the problem of enumerating all minimal integer solutions of a monotone system of linear inequalities. We first show that, for any monotone system of r linear inequalities in n variables, the number of maximal infeasible integer vectors is at most rn times the number of minimal integer solutions to the system. This bound is accurate up to a polylog(r) factor and leads to a polynomial-time reduction of the enumeration problem to a natural generalization of the well-known dualization problem for hypergraphs, in which dual pairs of hypergraphs are replaced by dual collections of integer vectors in a box. We provide a quasi-polynomial algorithm for the latter dualization problem. These results imply, in particular, that the problem of incrementally generating all minimal integer solutions to a monotone system of linear inequalities can be done in quasi-polynomial time.
A cost-effective estimation of uncaught exceptions in standard ML programs
Authors: Kwangkeun Yi, Sukyoung Ryu
Venue: Theoretical Computer Science (2002)

We present a static analysis that detects potential runtime exceptions that are raised and never handled inside Standard ML (SML) programs. This analysis will predict abrupt termination of SML programs, which is SMLs only one "safety hole". Even though SML program's control flow and exception flow are in general mutually dependent, analyzing the two flows are safely decoupled. Program's control flow is firstly estimated by simple case analysis of call expressions. Using this call-graph information, program's exception flow is derived as set constraints, whose least model is our analysis result. Both of these two analyses are proven safe and the reasons behind each design decision are discussed. Our implementation of this analysis has been applied to realistic SML programs and shows a promising cost-accuracy performance. For the ML-Lex program, for example, the analysis takes 1.36 s and it reports 3 may-uncaught exceptions, which are exactly the exceptions that can really escape. Our final goal is to make the analysis overhead less than 10% of the compilation time (compiling the ML-Lex takes 6-7 s) and to analyze modules in isolation. Copyright 2002 Elsevier Science B.V.
Design of Silicon IP Cores for Biorthogonal Wavelet Transforms
Authors: Shahid Masud, John V. McCanny
Venue: Journal of VLSI Signal Processing Systems (2001)

A methodology for rapid silicon design of biorthogonal wavelet transform systems has been developed. This is based on generic, scalable architectures for the forward and inverse wavelet filters. These architectures offer efficient hardware utilisation by combining the linear phase property of biorthogonal filters with decimation and interpolation. The resulting designs have been parameterised in terms of types of wavelet and wordlengths for data and coefficients. Control circuitry is embedded within these cores that allows them to be cascaded for any desired level of decomposition without any interface logic. The time to produce silicon designs for a biorthogonal wavelet system is only the time required to run synthesis and layout tools with no further design effort required. The resulting silicon cores produced are comparable in area and performance to hand-crafted designs. These designs are also portable across a range of foundries and are suitable for FPGA and PLD implementations.
