Open source computer algebra systems

ACM Communications in Computer Algebra, 2010
This survey will look at SymPy, a free and open source computer algebra system started in 2005 by the second author (O.C.). It is written entirely in Python, available from http://sympy.org. SymPy is licensed under the "modified BSD" license, as is its beautiful logo designed by Fredrik Johansson.

An Open-Loop Computer-Based Drug Infusion System

IEEE Transactions on Biomedical Engineering, 1987
This study reports the development of a computer-based infusion system and methodology to produce and maintain selected plasma concentrations. The method identifies pharmacokinetic infusion parameters for subjects from bolus injection response data, employs these values in control equations implemented by a portable microcomputer and computer ...

Computer-aided biochemical system analysis in open systems with environment simulation

Experientia, 1979
A computer-aided arrangement is described which allows kinetic and regulative studies with enzymes, organelles and cells in an open system. This is demonstrated with some simple examples.

Real-Time Computing in Open Systems for Manufacturing

Journal of Computing and Information Science in Engineering, 2000
This article reviews various mechanisms in languages and operating systems for deterministic real-time computing. Open-architecture systems will be defined and their applications in manufacturing will be addressed. Market directions for open-architecture manufacturing systems will be surveyed.

Open complex computer systems are no silver bullet

Proceedings. Fourth IEEE International Conference on Engineering of Complex Computer Systems (Cat. No.98EX193), 2002
Open systems, through the use of public, consensus based specifications or standards, are focussed on achieving the interoperability between, and the portability of components. In accommodating standards, open systems promise the advantages of plug-n-play technology, rapid prototyping and component re-use, while at the same time preventing system ...

Usable computing on open distributed systems

Proceedings of the 6th international workshop on Challenges of large applications in distributed environments, 2008
An open distributed system provides a best-effort guarantee on the quality of service provided to applications. This has worked well for throughput-based applications of the kind typically executed in Condor or BOINCstyle environments. For other applications, the absence of timeliness of correctness guarantees limit the utility or appeal of this ...

Online Engineering and Open Computational Systems

2006
We strongly believe that agent-oriented approaches to system development come with a natural level of abstraction and therefore have something valuable to offer. However, in doing so, any comprehensive agent-oriented methodology necessarily has to be grounded in issues and solutions of relevance in contemporary research and development areas such as ...

Maxima: An open source computer algebra system

Journal of Applied Econometrics, 2008
In one way or another, economists, especially econometricians, wind up spending a good part of their day interacting with computers. We may find ourselves writing Monte Carlo simulations designed to study the finite-sample behaviour of statistical procedures, conducting applied data analysis and visualization, or conducting mathematical analysis with ...

An Open System Approach to Quantum Computers

1997
Two of the basic characteristics of any computational procedure are: i) iteration of a basic operation ii) convergence to the result in a finite number of steps.

Modeling indirect interaction in open computational systems

WET ICE 2003. Proceedings. Twelfth IEEE International Workshops on Enabling Technologies: Infrastructure for Collaborative Enterprises, 2003., 2004
Open systems are part of a paradigm shift from algorithmic to interactive computation. Multiagent systems in nature that exhibit emergent behavior and stigmergy offer inspiration for research in open systems and enabling technologies for collaboration.
