ones. For example, a use case exclusively included by another one will be grouped with it to provide a more abstract use case belonging to a higher level use case diagram. As for the UML sequence diagrams abstraction, for each use case (i.e. validated cluster) it is possible to produce a sequence diagram whose objects derive from classes associated with the cluster’s entities, while interaction...

KRYŠTOF, J.: Towards an MDA-based approach for development of a structural scope of the presentation layer. Acta univ. agric. et silvic. Mendel. Brun., 2009, LVII, No. 6, pp. 123–132 This paper presents an approach for developing the presentation layer of so ware applications. The approach is based on the concept of the Model Driven Architecture (MDA) and uses a UML – based model of graphical u...

We present a tool-assisted platform-based design ow for embedded multiprocessor applications. The methodology relies on (1) a formal language which provides constructs to specify the platformindependent behavior of an application using an abstract execution model, and to describe the micro-architecture components of the hardware architecture, together with its compilation chain JAHUEL [1], and...

This project investigates collaboration within teams and the group-ware tools used to support them. This project expands on the work by Johnson & Hourizi on large group collaboration. With their framework as a starting point, the project will go onto apply this to a virtual-collaborative team in order to discover which factors within collaboration need to be supported by group-ware solutions. F...

As cluster computing becomes increasingly more accessible the need for tools to simplify the development and use of parallel simulations grows proportionally. One class of tools, steering and visualization middle-ware, promises to assist in code development as well as increase the value of the final simulation produced. We are interested in employing a steering and visualization middle-ware pac...
