among various practical measures used for restriction of the ground surface settlement in such tunnels driven in soft ground, selection of an appropriate excavation method plays a significant role. in this paper, employing suggested diagram by yu & chern, corresponding values of niayesh tunnel has been inserted into the diagram. later, two excavation methods namely: central diaphragm and si...

This paper presents a novel approach for generation of test cases from UML design diagrams. In this new generation scheme, we have considered use case diagram, activity diagram and sequence diagram. Our approach consists of converting the use case diagram into use case diagram graph (UDG), activity diagram into activity diagram graph (ADG) and sequence diagram into sequence diagram graph (SDG)....

BACKGROUND The sequence logo is a graphical representation of a set of aligned sequences, commonly used to depict conservation of amino acid or nucleotide sequences. Although it effectively communicates the amount of information present at every position, this visual representation falls short when the domain task is to compare between two or more sets of aligned sequences. We present a new vis...

This thesis is concerned with operational analysis of UML 2.x sequence diagram specifications. By operational analysis we mean analysis based on a characterization of the executions of sequence diagrams, or in other words an operational semantics for sequence diagrams. We define two methods for analysis of sequence diagram specifications – refinement verification and refinement testing – and bo...

In this paper, we consider the aesthetic criteria and constraints related to the layouts of UML sequence diagrams. We consider the applicability of the traditional graph drawing aesthetics in drawing sequence diagrams. Because of the special nature of sequence diagrams, many of these aesthetics are not applicable. Based on our view on how these diagrams are read or viewed, we propose some new a...

Software Testing plays a important role in Software development because it can minimize the development cost. We Propose a Technique for Test Sequence Generation using UML Model Sequence Diagram.UML models give a lot of information that should not be ignored in testing. In This paper main features extract from Sequence Diagram after that we can write the Java Source code for that Features Accor...

This paper presents a proposal for modeling agent mobility using UML Sequence Diagram. Our notation is focused on representing agent migration path and includes modeling of three basic mobility elements: agent creation, mobility path and current agent location. Four variants of graphical notation are presented. In a case study we explain one variant of notation that is the most suitable for giv...
