Activation diagrams in enzyme catalysis

Journal of Theoretical Biology, 1969
Three features of activation diagrams applied to enzyme catalysis are discussed. (1) The quantities which should be plotted in the ordinate of activation energy diagrams are the standard state quantities. This is called for by transition state theory (H. Eyring).

Activities and ternary phase diagrams

Calphad, 1997
Abstract A set of theoretical formulae for calculating activities along the liquid surface in ternary phase diagrams has been presented. These formulae are rigorous since no assumption is made in the derivation. The expressions are generalized and can be simplified to the forms presented by Pelton, Chou, Elliott and Gokcen under certain conditions ...

Extending interaction overview diagrams with activity diagram constructs

Software & Systems Modeling, 2009
UML2.0 introduced interaction overview diagrams (IODs) as a way of specifying relationships between UML interactions. IODs are a variant of activity diagrams that show control flow between a set of interactions. The nodes in an IOD are either inline interactions or references to an interaction.

MODELLING HEALTHCARE PROCESSES USING ROLE ACTIVITY DIAGRAMMING

International Journal of Modelling and Simulation, 2008
This paper presents an investigation into the use of Role Activity Diagramming (RAD) to model complex processes in the healthcare sector, with reference to the process of Cancer Care and Registration in Jordan. We argue that RAD models are generally useful as a means for understanding, analysing and improving complex processes. Also, we show that using

Test Case Generation Using Activity Diagram and Sequence Diagram

2013
In this paper, we present an approach to generate test cases by usingtogether the UML activity diagram and the sequence diagram. Our approach consists of transforming the sequence diagram into a graph called Sequence Graph (SG) and transforming the activity diagram to the Activity Graph (AG).

Testcases Formation Using UML Activity Diagram

2013 International Conference on Communication Systems and Network Technologies, 2013
Most of the software practitioners believe in Model-based test case generation. Advantages of this are the early detection of faults, reducing software development time etc. The most important part of the testing attempt is the test case generation.

Scrutinizing UML Activity Diagrams

2009
Building an information system involves two processes: conceptual modeling of the “real world domain” and designing the software system. Object-oriented methods and languages (e.g., UML) are typically used for describing the software system. For the system analysis process that produces the conceptual description, object-oriented techniques or ...

Making UML activity diagrams object-oriented

Proceedings 33rd International Conference on Technology of Object-Oriented Languages and Systems TOOLS 33, 2002
The way the activity diagram in the Unified Modeling Language is currently defined is not object-oriented. Activity diagrams specify data/object flow. We feel that the object-oriented principles should hold for every part of the standard for object-oriented analysis and design. Therefore this paper proposes a few small changes to the UML metamodel that

Skeblle: A New Kind of Diagramming Tool with Programmable Active Diagrams

2015
Diagramming tools range from manual free-form drawing tools to pre-programmed notation specific tools for UML or SDL, and further to fully programmatic tools like Pic or TikZ. In such tools, the diagrams are the end product, not available for further use, unaware of relations between diagrams or the ability to express one diagram as a function of ...
