Background: Human error is the most important cause of occupational and non-occupational accidents. Because, it seems necessary to identify, predict and analyze human errors, and also offer appropriate control strategies to reduce errors which cause adverse consequences, the present study was carried out with the aim of identifying human errors while operating meat grinder and offer sugg...

UML models consist of several diagrams of different types describing different views of a software system ranging from specifications of the static system structure to descriptions of system snapshots and dynamic behaviour. In this paper a heterogeneous approach to the semantics of UML is proposed where each diagram type can be described in its “natural” semantics, and the relations between dia...

We present an algorithm taking a Kirby diagram of closed oriented $4$-manifold to trisection the same manifold. This provides us with large number examples for diagrams $4$-manifolds since many Kirby-diagrammatic descriptions are known. That being said, does not necessarily provide particularly efficient diagrams. also extend this work non-orientable case.

Various object-oriented methodology is advocated in recent years. The Unified Modeling Language (UML), which is the unification modeling language of those notation, is becoming leading now. This paper proposes a supporting method of diagrams generation with the transformation rules in UML to draw diagrams eliminated contradiction in a short time by using common elements which other diagrams hav...

Agent UML (AUML) is an extension of the standard objectoriented modelling language UML adapted for agent-based systems. In AUML sequence diagrams are extended to describe specific dynamic aspects of agents including dynamic role assignment, nondeterministic choice in agent decisions and concurrent communication. These diagrams are used to describe agent interaction protocols. We describe some o...

In order to perform daily maintenance and repair tasks in complex electrical and mechanical systems, technicians commonly utilize a large number of diagrams and documents detailing system properties in both electronic and print formats. In electronic document views, users typically are only provided with traditional pan and zoom features; however, recent advances in information visualization an...

Diagrams are frequently used to document various components of information systems, from the procedures established for user-system interaction, to the structure of the database at the system’s core. Past research has revealed that diagrams are not always used as effectively as their creators intend. This study proposes a theory of diagrammatic attention management to contribute to the explorat...
