Effect of Cu concentration on the reactions between Sn-Ag-Cu solders and Ni
Authors: C. E. Ho, R. Y. Tsai, Y. L. Lin, C. R. Kao
Venue: Journal of Electronic Materials (2002)

The reaction between the Sn-Ag-Cu solders and Ni at 250°C for 10 min and 25 h was studied. Nine different Sn-Ag-Cu solders, with the Ag concentration fixed at 3.9 wt.% and Cu concentrations varied between 0.0-3.0 wt.%, were used. When the reaction time was 10 min, the reactions strongly depended on the Cu concentration. At low-Cu concentrations (≤0.2 wt.%), only a continuous (Ni1-xCux)3Sn4 layer formed at the interface. When the Cu concentration increased to 0.4 wt.%, a continuous (Ni1-xCux)3Sn4 layer and a small amount of discontinuous (Cu1-yNiy)6Sn5 particles formed at the interface. When the Cu concentration increased to 0.5 wt.%, the amount of (Cu1-yNiy)6Sn5 increased and (Cu1-yNiy)6Sn5 became a continuous layer. Beneath this (Cu1-yNiy)6Sn5 layer was a very thin but continuous layer of (Ni1-xCux)3Sn4. At higher Cu concentrations (0.6-3.0 wt.%), (Ni1-xCux)3Sn4 disappeared, and only (Cu1-yNiy)6Sn5 was present. The reactions at 25 h also depended strongly on the Cu concentration, proving that the strong concentration dependence was not a transient phenomenon limited to a short reaction time. The findings of this study were rationalized using the Cu-Ni-Sn isotherm. This study shows that precise control over the Cu concentration in solders is needed to produce consistent results.

E-Trustworthy: bridging the Balkans
Authors: Paul S. Raines
Venue: Software Magazine (2002)

TO THE UNINFORMED OUTSIDER, a corporate IT organization may appear to be a fairly homogeneous group of gadget-toting, fashion-challenged, techno-babbling geeks. An IT insider would admit to all of the above except the description of being homogeneous. In fact, an IT department is a seething cauldron of competing factions staffed with widely varying personality types. At one end of the spectrum are the developers---the consummate artists of information technology. At the other end are the information security professionals---the watchdogs of the corporate jewels. They seldom see eye to eye. It is into this Balkanized world of information technology that this article ventures bravely forth.

Authors: Frederick R. Stocker, Thomas Minsker
Venue: Proceedings of the 1st annual conference on Computer graphics and interactive techniques (1974)

The Pennsylvania State University Computation Center is currently performing research and development in the areas of communication and perception to expand a user's ability to function in a dynamic interactive computer graphics environment. One aspect of this research is the development of an on-line approach to graphics comprehension and learning through user-interaction.withgeometric imagery on a cathode-ray-tube. Such geometric imagery allows fundamental concepts of computer graphics to be readily conveyed to the user with or without the guidance of a knowledgeable graphics programmer. This paper, together with a film, describes the nature of such an approach. The film illustrates some of the aspects of system/user interaction embodied in the geometric perception and communication package in development at the Computation Center.

Nonparametric Estimation and Adaptive Control of Functional Autoregressive Models
Authors: Bruno Portier, Abderrahim Oulidi
Venue: SIAM Journal on Control and Optimization (2000)

This paper deals with nonparametric estimation and adaptive control of nonlinear systems of the form $X_{n+1}\ =\ f(X_n)\ +\ U_n\ +\ \xi_{n+1}\ (n \in \bkN)$ where the state $X_n$ is observed, f is an unknown function, and the control Un is chosen in order to track a given reference trajectory. We estimate the function f using a nonparametric estimator and study two adaptive control laws built from this nonparametric estimator and derived from the self-tuning control. The first one can be used for open-loop stable systems and requires an additional exciting noise. The second one needs some a priori knowledge on function f but allows us to control open-loop unstable systems. We establish some general results on the nonparametric estimator of f like the uniform almost sure convergence over dilating sets and then prove that both adaptive control laws are asymptotically optimal in quadratic mean. In addition, we give a strongly consistent estimator of the covariance matrix of the unobservable white noise $\xi_n$.

Declarative problem-solving using the DLV system
Authors: Thomas Eiter, Wolfgang Faber, Nicola Leone, Gerald Pfeifer
Venue: Logic-based artificial intelligence (2000)

The need for representing indefinite information led to disjunctive deductive databases, which also fertilized work on disjunctive logic programming. Base on this paradigm, the DLV system has been designed and implemented as a tool for declarative knowledge representation. In this paper, we focus on the usage of DLV for solving problems in a declarative manner and report on experiments that we have run on a suite of benchmark problems. We discuss how problems can be solved in a natural way using a "Guess&Check"-paradigm where solutions are guessed and verified by parts of the program. Furthermore, we describe various front-ends that can be used for solving problems in specific applications. The experiments show that due to the ongoing implementation efforts, which include fine -tuning of the underlying algorithms, successive and significant performance improvements have been achieved during the last two years. The results indicate that DLV is capable of solving some complex problems quite efficiently.
Analysis of Timing-Based Mutual Exclusion with Random Times
Authors: Eli Gafni, Michael Mitzenmacher
Venue: SIAM Journal on Computing (2002)

Various timing-based mutual exclusion algorithms have been proposed that guarantee mutual exclusion if certain timing assumptions hold. In this paper, we examine how these algorithms behave when the time for the basic operations is governed by probability distributions. In particular, we are concerned with how often such algorithms succeed in allowing a processor to obtain a critical region and how this success rate depends on the random variables involved. We explore this question in the case where operation times are governed by exponential and gamma distributions, using both theoretical analysis and simulations.
Mixed finite element methods for a class of nonlinear reaction diffusion problems
Authors: Luis Ferragut, Isabel Asensio
Venue: Neural, Parallel Scientific Computations (2002)

A mixed finite element approximation is presented for a class of non-linear reaction diffusion problems with a wide applicability. Some results about the existence and uniqueness of weak solutions are resumed. Semidiscrete error estimates are established assuming only Lipschitz regularity of the reactive term and nondecreasing of the diffusive term and demostrated with a new technique. The proofs of this error estimates are described in detail, first in the dual norm, and then in the L2-norm. As an application, a model for numerically simulating wildland fires is presented.

ATLAS: a scalable network framework for distributed virtual environments
Authors: Dongman Lee, Mingyu Lim, Seunghyun Han
Venue: Proceedings of the 4th international conference on Collaborative virtual environments (2002)

A distributed virtual environment (DVE) is a software system that allows users on a network to interact with each other by sharing a common view of their states. As users are geographically distributed over large networks like the Internet and the number of users increases, scalability is a key aspect to consider for real-time interaction. Various solutions have been proposed to improve the scalability in DVE systems but they are either focused on only specific aspects or customized to a target application. In this paper, we classify the approaches for improving scalability of DVE into four categories: communication architecture, interest management, concurrency control, and data replication. We then propose a scalable network framework for DVEs, ATLAS. Incorporated with our various scalable schemes, ATLAS meets the scalability of a system as a whole. By providing system developers with a set of APIs as a network infrastructure, ATLAS intends to support various applications The integration experiences of ATLAS with several virtual reality systems ensures the versatility of the proposed solution.
Improved retrieval effectiveness through impact transformation
Authors: Vo Ngoc Anh, Alistair Moffat
Venue: Proceedings of the 13th Australasian database conference - Volume 5 (2002)

Users of web search engines are notoriously parsimonious in their use of search terms, and search effectiveness has tended to be relatively poor on the resulting short queries, especially when compared against the good performance attained by recent systems when working with long TREC-like queries. In this paper we examine the reasons why short queries are hard to deal with, and propose a modification to the vector-space paradigm, which we call impact transformation. Experiments with a collection of web data and web queries shows that impact transformation significantly boosts retrieval effectiveness. Moreover, the use of quantised values in the transformation allows extremely fast query processing.
