this work is conducted to obtain mechanical properties of microtubule. for this aim, interaction energy in alpha-beta, beta-alpha, alpha-alpha, and beta-beta dimers was calculated using the molecular dynamic simulation. force-distance diagrams for these dimers were obtained using the relation between potential energy and force. afterwards, instead of each tubulin, one sphere with 55 kda weight ...

Sequence diagrams are a widely used design notation for describing software behavior. Many reusable software artifacts such as design patterns and design aspects make use of sequence diagrams to describe interaction behavior. When a pattern or an aspect is reused in an application, it is important to ensure that the sequence diagrams for the application correctly refines the corresponding seque...

The UML (Unified Modeling Language) has been widely accepted as a standard language for object-oriented analysis and design. Among the UML diagrams, one of the most difficult and time-consuming diagrams to develop is the object interaction diagram (OID), which is rendered as either a sequence diagram or a collaboration diagram. Our experience shows that developers have significant trouble in un...

This paper discusses (a) the design and (b) the development of easy to use interactive TV applications. (a) Because of the specifics of interaction design for interactive TV applications specific design guidance for interactive TV is needed. This paper investigates how the design of interactive TV applications can benefit from existing software usability knowledge as well as from the interactio...

Recently, aspect-oriented approaches have resulted in a tremendous impact on the processing of broadly scoped properties during the development of software systems. However, the weaving mechanism of these crosscutting concerns cannot be easily represented with the extant uniÞed modeling language (UML) notation at the early stage of software development life cycle. As an attempt toward the inves...

Computer-based teaching material must contain animation or interaction to offer substantial benefits over delivery on paper. Technology developed for use in web browsers — especially Java and JavaScript — makes it relatively easy to add interactive diagrams to web pages. The objectoriented nature of Java is well suited to developing a large collection of interactive diagrams (applets) for teach...

We develop and apply several novel methods quantifying dynamic multi-agent team interactions. These interactions are detected information-theoretically and captured in two ways: via (i) directed networks (interaction diagrams) representing significant coupled dynamics between pairs of agents, and (ii) state-space plots (coherence diagrams) showing coherent structures in Shannon information dyna...
