An Object-Oriented Design for Two-Dimensional Vortex Particle Methods

Abstract: Support for units of measurement is the main topic of the research project described in this thesis. In this interdisciplinary project, knowledge from the fields of computing and auditing is combined to investigate the possibilities of unit-aware organization modeling. Such modeling also requires computations in proper units of measurement and thus a unit-aware programming language. The first part of this thesis describes a unit-aware matrix type based on dimensioned linear algebra that infers principle types for linear algebra expressions. In the second part the matrix type is used to construct unit-aware value cycle models from the field of control and auditing.

Abstract: The multidisciplinary requirements of current computational modeling problems preclude the development of scientific software that is maintained and used by selected scientists. The multidisciplinary nature of these efforts requires the development of large scale software projects established with a wide developer and user base in mind. This article describes some of the software-engineering practices adopted in a scientific-software application for a laser-induced incandescence community model. The project uses an Agile and Test-Driven Development approach to implement the infrastructure for the development of a collaborative model that is to be extended, modified, and used by different researchers. We discuss some of the software-engineering practices that can be exploited through the life of a project, starting with its inception when only a hand full of developers are contributing to the project and the mechanism we have put in place in order to allow the natural expansion of the model.

Abstract: Matplotlib is a 2D graphics package used for Python for application development, interactive scripting,and publication-quality image generation across user interfaces and operating systems

Abstract: From the Publisher: Written by Bjarne Stroustrup, the creator of C, this is the world's most trusted and widely read book on C. For this special hardcover edition, two new appendixes on locales and standard library exception safety have been added. The result is complete, authoritative coverage of the C language, its standard library, and key design techniques. Based on the ANSI/ISO C standard, The C Programming Language provides current and comprehensive coverage of all C language features and standard library components. For example: abstract classes as interfaces class hierarchies for object-oriented programming templates as the basis for type-safe generic software exceptions for regular error handling namespaces for modularity in large-scale software run-time type identification for loosely coupled systems the C subset of C for C compatibility and system-level work standard containers and algorithms standard strings, I/O streams, and numerics C compatibility, internationalization, and exception safety Bjarne Stroustrup makes C even more accessible to those new to the language, while adding advanced information and techniques that even expert C programmers will find invaluable.

Abstract: An algorithm is presented for the rapid evaluation of the potential and force fields in systems involving large numbers of particles whose interactions are Coulombic or gravitational in nature. For a system ofNparticles, an amount of work of the orderO(N2) has traditionally been required to evaluate all pairwise interactions, unless some approximation or truncation method is used. The algorithm of the present paper requires an amount of work proportional toNto evaluate all interactions to within roundoff error, making it considerably more practical for large-scale problems encountered in plasma physics, fluid dynamics, molecular dynamics, and celestial mechanics.

Abstract: Python offers basic facilities for interactive work and a comprehensive library on top of which more sophisticated systems can be built. The IPython project provides on enhanced interactive environment that includes, among other features, support for data visualization and facilities for distributed and parallel computation
