ABSTRACT This paper describes a distributed UML virtual machine, called Matilda, which allows developers to design their applications as UML models and directly execute the models. Matilda accepts a UML model as an input, validates it against the UML metamodel, constructs a Java abstract syntax tree (JAST) according to the input model, and executes Java bytecode generated from the JAST. The arc...

This paper describes a distributed UML virtual machine, called Matilda, which allows developers to design their applications as UML models and directly execute the models. Matilda accepts the UML models that developers define (class and sequence diagrams), validates them against the UML metamodel, constructs a Java abstract syntax tree (JAST) that corresponds to the user-defined models, and exe...

The MATILDA hypermedia authoring framework has been developed in an attempt to address a number of issues related to authoring process, information reuse and application maintainability. In particular, the framework addresses information representation and usage issues, and has been used in the development of a series of data models. The architecture of MATILDA separates the information domain ...

Lipids, proteins and starch are the main storage products in oat seeds. As a first step in elucidating the regulatory mechanisms behind the deposition of these compounds, two different oat varieties, 'Freja' and 'Matilda', were analysed during kernel development. In both cultivars, the majority of the lipids accumulated at very early stage of development but Matilda accumulated about twice the ...

Present authoring issues, such as managing large-scale complexity, information reuse and application maintainability have yet to be effectively addressed by current authoring approaches. This problem has motivated the MATILDA hypermedia project, which has three primary development areas; frameworks, information models, and process models. This paper presents the MATILDA information model. This ...

The paper suggests a review of the existing approaches to the analysis of the “project success” concept. It focuses on the exploration of possible indicators for its evaluation and the identification of the critical success factors. The paper considers in particular the critical factors of project success regarding projects funded by the Operational Programmes of the EU in Bulgaria. It suggests...

Although so much stress is laid on the physiological reactions of bacteria in their identification and classification, little investigation (except to distinguish aerobic from anaerobic forms) has been devoted to the fundamental process of respiration in these organisms. In order to throw some light on the nature of this process and to compare the results with those obtained with other plants a...

Oat (Avena sativa) is unusual in comparison with other cereals since there are varieties with up to 18% oil content. The lipid content and fatty acid composition in different parts of the grain during seed development were characterized in cultivars Freja (6% oil) and Matilda (10% oil), using thin-layer and gas chromatography, and light and electron microscopy. The majority of lipids (86-90%) w...
