Abstract Formal definitions of syntax and semantics for the static and dynamic models in Object Oriented methods are already defined. But the behavior of interacting objects is not formalized. In this paper, we defined the common behavior of interacting objects in terms of process algebra using sequence diagram in UML and regularized properties of interacting objects. Based on the results, we can develop a formal specification by. using of the object interaction instead of the existence dependency suggested by M. Snoeck and G. Dedene[9].

The irrigation facilities are managed systematically and a facility is independent at the view of shape and function. The design of the irrigation facility is the formulated process with independent objectives. So its process is accordance to object-oriented concept. The design of irrigation facilities is classified into several steps. In these steps, the design data is made and the various problems are solved and consolidated with analysis and decision. In order to achieve our goal of constructing an efficient integrated design system, the results from the design should be able to be systematically connected and re-used. In the study, the design task of irrigation facility, the integrated design system for (IDSAF) is to be developed using the object-oriented methods, and then its applicability will be examined.

The notion of object oriented analysis and design in software engineering has many rewards that aid the programmer to have an understanding of and improve the program efficaciously. Object oriented metrics helps rather a lot to a programmer or developer to comprehend and unravel the thing-oriented trouble readily and exactly. Object oriented metrics helps in examining the usefulness of object oriented applied sciences or in simple phrases Object-oriented metrics depict characteristics of object-oriented programming. The intention of this paper is to have an understanding of concerning the UML, Object oriented evaluation and design and the way it plays in UML.

The RSS Reader is a software application that assist users easily to read and collect contents which are frequently changeable syndicated contents of RSS format that published on the web. This paper presents a formula software design based on RUP object-oriented design method for implementing the RSS Reader. We extract a use case based on requirements for implement of the RSS Reader and propose a domain concept model by. Using above artifacts, we extract event to generate between users and, the RSS Reader and logical architecture. So, we design classes and packages of the RSS Reader. As proposed a formula software design about the RSS Reader in early stage, it can make the RSS Reader with a variety of characters easily based on these.

This Pager presents an object-oriented analysis and design for Remote Examination System on Internet. The UML is used for describing the process of analyzing and designing the system. The system is composed of the parts: Question Generation part that professors make questions, Question Answer part that students answer the questions. By object-oriented analysis and design, the system inherits the advantages of object-oriented methodology. All the results are retained on database on server-side. This system can be integrated with the Cyber-University System, and substituted for off-line paper-based tests or adopted to on-line poll applications on Internet.

Fiber reinforced composites fabricated by the resin film infusion (RFI) process, which is one of the outof-autoclave process, have the advantage of significantly reducing the processing cost in large structures while having excellent mechanical properties and uniform impregnation of the resin. In this study, we applied RFI carbon fiber composites to unmanned aerial vehicle structures to improve structural safety and achieve weight reduction. The tensile test results showed that the strength was 46% higher than that of generic T300 grade plain weave carbon fiber composites. As a result of the layup design and finite element analysis of the composite wing structure using the above material properties, the wing tip deflection is decreased by 31%, the structural safety factor is increased by 28% and the weight of the entire structure can be reduced by more than 10% compared to the reference model using glass fiber composite material.
