A number of software tools are available that do symbolic computation that can facilitate the theoretical analysis of a mathematical model. We made use of one these tools, Mathematica (Wolfram, 1988), to implement the global familiarity memory models of Gillund and Shiffrin (1984) and Murdock (1982, 1983). We describe our implementation, and illustrate the flexibility and efficiency of use that...

Abstract The study constitutes an analysis of the durability dies used in first operation producing valve forgings from chromium–nickel steel (NCF 3015) for motor trucks. average (subjected to standard thermal treatment and nitriding) this equals about 800 forgings. To perform in-depth effect nitrided layer thickness (0.1 mm 0.2 mm) tool material (W360 QRO90) on possibilities increasing die dur...

During the last years several new tools applicable to protein analysis have made available on the IBIVU web site. Recently, a number of tools, ranging from multiple sequence alignment construction to domain prediction, have been updated and/or extended with services for programmatic access using SOAP. We provide an overview of these tools and their application.

The range of tools designed to help build agent-based models is briefly reviewed. It is suggested that although progress has been made, there is much further design and development work to be done. Modelers have an important part to play, because the creation of tools and models using those tools proceed in a dialectical relationship.

In this paper we present simple methods for construction and evaluation of finite-state spell-checking tools using an existing finite-state lexical automaton, freely available finite-state tools and Internet corpora acquired from projects such as Wikipedia. As an example, we use a freely available open-source implementation of Finnish morphology, made with traditional finite-state morphology to...

ABSTRACT One of the major problems of academic research is the unavailability of appropriate tools where researchers can develop and evaluate their ideas. Research groups tend to spend a significant amount of time in developing tools which results in an abundance of incomplete tools which do not provide sufficient features for other groups to use. Often these tools are never made public which m...
