Incomplete Multilevel Cholesky Factorizations
Authors: J. C. Diaz, K. Komara
Venue: SIAM Journal on Matrix Analysis and Applications (2000)

Adaptive in-time local grid refinement techniques use multilevel local discretizations designed to achieve local accuracy. The changing nature of the matrix structure of the linear systems arising from the multilevel local discretizations requires flexible approximate factorizations that focus on local components and coordinate their interaction. The solution of these composite grid systems with Krylov solvers is considered. The selection of an adequate preconditioner is crucial. The incomplete Cholesky (IC) factorization of the composite matrix and the inexact BEPS preconditioner are two such potential preconditioners. The inexact BEPS preconditioner can be constructed and applied with significantly more flexibility than the IC factorizations of the composite multilevel grid matrix.An extension of the IC factorizations for matrices arising from discretizations of self-adjoint PDEs on multilevel composite grids is proposed. The resulting factorization is referred to as the incomplete multilevel Cholesky (IMC) factorization. The IMC factorization is spectrally equivalent to the IC factorization of the matrix of the composite grid system.IMC factorization can be constructed with the same flexibility as the inexact BEPS preconditioner. The application of IMC factorization is achieved via a multilevel LLT-cycle consisting of a forward elimination pass proceeding downward on the grids from fine to coarse followed by an reverse-order upward back substitution pass.The application of multilevel factorization as a preconditioner requires roughly one-half as many operations as the inexact BEPS preconditioner. The numerical results illustrate the potential of the method.
A domain based internal schema for relational database machines
Authors: M. Missikoff
Venue: Proceedings of the 1982 ACM SIGMOD international conference on Management of data (1982)

In this paper a method for relational database storage organization is presented.The method is based upon a disaggregation of the relations and a subsequent reaggregation to form the domains on which the relations are defined.A hierarchical organization of the domain is proposed in order to keep track of the relational entities (i.e. relations, tuples and attributes) that insist on the values present in the domains.Then we introduce an implementation technique, referred to as Data Pool, suitable to be processed by a database machine capable of "on the fly" track processing.Finally we present an analytic evaluation of the DP method and an example of database and query with performance comparison of the DP method with the most common flat file technique.The proposed method appears to be generally advantageous in storage occupancy; in data retrieval operations it is extremely effective when joins between permanent relations are performed. Good performances can be achieved with other relational operations using proper parallel architectures and, when temporary relations are involved, using special purpose devices.

Interactive ray tracing of time varying data
Authors: Erik Reinhard, Charles Hansen, Steve Parker
Venue: Proceedings of the Fourth Eurographics Workshop on Parallel Graphics and Visualization (2002)

We present a simple and effective algorithm for ray tracing iso-surfaces of time varying data sets. Each time step is partitioned into separate ranges of potentional iso-surface values. This creates a large number of relatively small files. Out-of-core rendering is implemented by reading for each time step the relevant iso-surface file, which contains its own spatial subdivision as well as the volumetric data. Since any of these data partitions is smaller than a single time step, the I/O bottleneck is overcome. Our method capitalizes on the ability of modern architectures to stream data off disk without interference of the operating system. Additionally, only a fraction of a time-step is held in memory at any moment during the visualization, which significantly reduces the required amount of internal memory.

Real Java for real time - gain and pain
Authors: Anders Nilsson, Torbjörn Ekman, Klas Nilsson
Venue: Proceedings of the 2002 international conference on Compilers, architecture, and synthesis for embedded systems (2002)

The Java programming language, being a portable and safe object-oriented language, has gained much interest among embedded and real-time systems developers. However, standard Java implementations exhibit problems with performance, memory footprint, and predictability. The question is then, are these limitations inherent in the technology?Reviewing run-time aspects and the possibility to compile Java to native code, reveals some real limitations as well as common misconceptions. Investigation of the real limitations shows that for implementing real-time Java on small embedded platforms, native compilation via C is an appropriate solution for many platforms and applications.A revised technique for Java-compatible memory management is proposed to reduce latencies, and linkage of externally generated (C) code with natively compiled Java is considered in a prototype that has been implemented. Based on application demands and experimental verification, we find that real-time Java can, and should, retain the standard simple Java memory model to the programmer.

The Use and Properties of Tikhonov Filter Matrices
Authors: Marten Gulliksson, Per-Åke Wedin
Venue: SIAM Journal on Matrix Analysis and Applications (2000)

We consider the concept of Tikhonov filter matrices in connection with discrete ill-posed and rank-deficient linear problems. Important properties of the Tikhonov filter matrices are given together with their filtering and regularization effects. We also present new perturbation identities for the Tikhonov regularized linear least squares problem using filter matrices generalizing well-known perturbation identities for the linear least squares problem and pseudoinverses.
An architecture for query optimization
Authors: Arnon Rosenthal, David Reiner
Venue: Proceedings of the 1982 ACM SIGMOD international conference on Management of data (1982)

We describe an optimizer for relational queries to databases stored as flat files and Codasyl networks. We include sophisticated manipulations on a broad range of direct access structures (DAS's). To achieve this with minimum additional code, we allow operations like sort, scan, and join to apply to DAS's, and categorize indexes and other DAS's in terms of the operations which can be performed on them. Our storage model, based on indivisible units of access and a small set of associated physical operators, provides a uniform interface to both relational and Codasyl storage mechanisms. The optimizer derives a sequence of internal data structures at successively more detailed levels. For a given query, a graph representing an overview of alternative joins is constructed, and then used to derive a physical graph which considers the physical attributes (location and sort order) of the data objects involved. Using cost predictions and other heuristics, the optimizer prunes the physical graph to produce a final access strategy tree. This layered approach and reliance on primitive operators make explicit (and permit changes to) the universe of possible strategies for the query at hand, and ease extension of the optimizer to new storage structures.

Performance evaluation of two concurrency control mechanisms in a distributed database system
Authors: Wen-Te K. Lin
Venue: Proceedings of the 1981 ACM SIGMOD international conference on Management of data (1981)

Two concurrency control mechanisms, the SDD-1 system and Dynamic Timestamping Method, are evaluated in terms of protocol synchronization delays and average transaction response time by using simulation. Relationship among average protocol synchronization delay, average transaction response time, average 10 service delay, communication delay, and other system parameters is analyzed by using regression analysis. The statistical distribution functions of transaction response times and synchronization delays are then examined to see if they fit exponential, erlangian, or some other distribution functions.

A security scheme for aglets
Authors: Kouichi Ono, Hideki Tai
Venue: Software&mdash;Practice Experience (2002)

Aglets, a framework and runtime platform for mobile agents developed by the IBM Tokyo Research Laboratory, is an advanced system of mobile agents written in Java, and is already used in some commercial applications. Using mobile agent technologies provides potential benefits to applications, but they also pose security threats to those applications. These threats not only come as malicious agents, but also in the form of malicious hosts. In this paper we introduce security features against these threats. Access control and message protection can prevent attacks by malicious agents. Server authentication allows agents to avoid movement to malicious hosts and blocks suspicious agents coming from malicious hosts.

Graphics in business decision making
Authors: Irvin M. Miller
Venue: Proceedings of the 1st annual conference on Computer graphics and interactive techniques (1974)

Mountains of data can be converted into easily digestible graphs so that decision makers can grasp the peaks and trends of economic situations and make rapid and confidential decisions.We will study how we can define simple models using a graphic-based Industrial Dynamics system (Forrester of MIT), then interact with them symbionically to obtain graphs of various manufacturing or sales considerations. We will proceed to apply graphic analysis techniques to these graphs in order to produce curves that identify the sensitivities of the analysis, to reinforce confidence in the decision to be made. Finally, we will discuss the progress and the potential of graphics in business decision making. The ACM Portal is published by the Association for Computing Machinery. Copyright © 2010 ACM, Inc.

Squarish k-d Trees
Authors: Luc Devroye, Jean Jabbour, Carlos Zamora-Cura
Venue: SIAM Journal on Computing (2000)

We modify the k-d tree on [0,1]d by always cutting the longest edge instead of rotating through the coordinates. This modification makes the expected time behavior of lower-dimensional partial match queries behave as perfectly balanced complete k-d trees on n nodes. This is in contrast to a result of Flajolet and Puech [ J. Assoc. Comput. Mach., 33 (1986), pp. 371--407], who proved that for (standard) random k-d trees with cuts that rotate among the coordinate axes, the expected time behavior is much worse than for balanced complete k-d trees. We also provide results for range searching and nearest neighbor search for our trees.
A homogeneous formulation for lines in 3 space
Authors: James F. Blinn
Venue: ACM SIGGRAPH Computer Graphics (1977)

Homogeneous coordinates have long been a standard tool of computer graphics. They afford a convenient representation (for) various geometric quantities in two and three dimensions. The representation of lines in three dimensions has, however, never been fully described. This paper presents a homogeneous formulation for lines in 3 dimensions as an anti-symmetric 4x4 matrix which transforms as a tensor. This tensor actually exists in both covariant and contravariant forms, both of which are useful in different situations. The derivation of these forms and their use in solving various geometrical problems is described.

Modelling location operations in UMTS networks
Authors: Marcien Mackaya, Ousmane Koné, Richard Castanet
Venue: Proceedings of the 5th ACM international workshop on Modeling analysis and simulation of wireless and mobile systems (2002)

This paper is concerned with design issues in telecommunication services. We propose a modelling and simulation approach for location operations in UMTS networks. These operations involve entities belonging to both core network and access network. The proposed model is based on formal techniques and represents functional behaviour of network elements. The model is intended for simulation and analysis in order to detect possible inconsistencies and to design test patterns for implementations of 3G-networks. The results show that the design of the model is good and tests patterns are automatically produced.
