Developing VDM ++ operations from UML diagrams
The Unified Modelling Language (UML) is widely accepted as the standard notationfor Object-Oriented methods. However, one of its major problem is itslack of formal semantics. The development of the Object Constraints Language(OCL) in the last few years seems to be the answer to this problem, but …

Automating component-based testing from UML models
… tested in an automated fashion with the help of UML models. First, these objects should be modeled in UML, using certain extensions and modeling conventions. Then, an automated software-testing program can read the UML diagrams and generate testing scripts which drive the components …

Early component-based reliability assessment using UML based software models
… uses Rational Rose Unified Modeling Language (UML) diagrams to predict the reliability of component-based software. ECRA provides the user with an easy interface to annotate the UML diagrams and uses a Bayesian algorithm to predict the system reliability. This thesis presents the methodology of …

Evolution of batch-oriented COBOL systems into object-oriented systems through unified modelling language.
… method(s) are specified to extract a series of UML diagrams from this code in order to provide documentation of this system. This thesis outlines which of the UML diagrams, as specified in the UML Specifications version 1.5, can be extracted using the specified methods and under what conditions …

Understanding cognitive differences in processing competing visualizations of complex systems
Node-link diagrams are used represent systems having different elements and relationships among the elements. Representing the systems using visualizations like node-link diagrams provides cognitive aid to individuals in understanding the system and effectively managing these systems. Using …

Estimating reliability impact of biometric devices in large scale applications
… ECRA technique to biometrics is new. Using the UML diagrams and the ECRA tool, the reliability of the system is predicted.

Using Codecharts for formally modelling and automating detection of patterns with application to Security Patterns
… which consist of informal statements as well as UML diagrams. Security patterns are design patterns for specific security problems domains, therefore, they are described in the same manner. However, the current catalogues describing security patterns contain a level of ambiguity and imprecision. …

Model driven communication protocol engineering and simulation based performance analysis using UML 2.0
… the purpose. With the growth in popularity of UML the most obvious question to ask is whether one can translate one or more UML diagrams describing a system to a performance model. Until the advent of UML 2.0, that has been an impossible task since the semantics were not clear. Even though the …

Feature-based Approach to Bridge the Information Technology and Business Gap
… them into a feature model (presented in UML diagrams); this is represented as a top-to-middle process. The second phase is a reverse engineering process. A system program code is sliced into modules and transformed into feature-based models (again, in UML diagrams); these are represented …

Using the Unified Modeling Language (UML) to represent artefacts in the Zachman Frameword
… approach will be used to describe and decompose UML diagrams into their respective building blocks. A top down approach will be used to determine views that are important to enterprises during the system development lifecycle. The importance of providing graphical representations to describe …

The Effects of Business Process Management Cognitive Resources and User Cognitive Differences on Outcomes of User Comprehension
… as metagraphs and Unified Modeling Language (UML) diagrams, portray business process information (BPI) and prompt BPM managers to apply their training and expertise to deal with BPM situations. As a result, GPMs are the primary information artifacts for decision-making and communication among …

Qualitative Software Engineering and Parallel Sorting Algorithm for Real Numbers
… and Event-B modelling for class and Use case diagrams. Now a days distributed and parallel applications are most popular and are used in applications like telecommunications and aircraft systems with complex computations. It is very important to define the exact properties and features of …

Knowledge Representation and Decision Support for Managing Product Obsolescence
… developed in a systematic way with the use of UML diagrams. The generality of the developed ontology is demonstrated with distinct examples. Diminishing Manufacturing Sources and Material Shortages (DMSMS) obsolescence provides the basis for this study. Second, an ontology-based hybrid approach …

Using Model Driven Engineering to Reliably Automate the Measurement of Object-Oriented Software
… artifacts such as Unified Modelling Language (UML) diagrams as well as implementation artifacts such as program code are considered as different models of a software system. Working at the model level provides a whole new set of constructs to be measured and recent research has moved towards …

Efficient visual navigation of hierarchically structured graphs
… ranging from biochemical pathways to UML diagrams. Modifying the intermediate results of every step of the original algorithm locally, the update scheme is more efficient than re-applying the entire algorithm after expansion or contraction. As our experimental results on randomly …
