  • Recently, the object-oriented design is the major paradigm for software development. Most systems are following this paradigm, but the past studies for a video conversation domain were not based on full-scale object-oriented design. Thus, this paper presents an systematical architecture design using UML for a video conversation system that is well-known and has high rate of usefulness. It analysis a video conversation system that has much demand of service as systematical functional/non-functional requirements, and the object-oriented design applying '4+1 View Model' guarantees the reusability of a component and makes it possible to extend a system by adding components as needed. Consequently, it is expected that the components of video conversation system designed by this paper will be useful the other video conversation systems and will be expanded to web environment.

  • In this study, an automation tool was developed for rapid evaluation of machine tool spindle designs with automated three-dimensional finite element analysis (3D FEA) using solid elements. The tool performs FEA with the minimum data of point coordinates to define the section of the spindle shaft and bearing positions. Using object-oriented programming techniques, the tool was implemented in the programming environment of a CAD system to make use of its objects. Its modules were constructed with the objects to generate the geometric model and then to convert it into the FE model of 3D solid elements at the workbenches of the CAD system using the point data. Graphic user interfaces were developed to allow users to interact with the tool. This tool is helpful for identification of a near optimal design of the spindle based on, for example, stiffness with multiple design changes and then FEAs.

  • Recently, the distributed processing environments provide various open multimedia serivces through telecommunication network and have been developing into information networking structure based on object oriented concepts and distributed systems which can apply new services with a few changes the existing networks. This paper proposes the object group model which is the collection of objects and can functionally and efficiently manage the individual object. this paper presents the analysis of the requirement and the function specifications to propose the object group model, and depicts the functional structure in details using its analysis. The goal of this paper is to decrease the complexity of the object's management and to voercome the limitations of among the components of object group for management and service functions based on our proposed the object group model and show interaction procedures to eTD (event tracing diagram)s and finally we design the object group model by TINA-ODL.

  • This paper introduces the concepts of UML(Unified Modeling Language) and the applying this technique for implementing voltage stability analysis program. Conventional function-oriented software development methodologies are inadequate to support further maintenance and enhancement. To overcome drawbacks of these methodologies, this paper proposes applying object-oriented technology for voltage stability evaluation software development. In this paper, a modal analysis approach, a steady-state voltage stability evaluation method, is used and UML is applied to the analysis and design for software development.

  • Analysis model focuses only on functional requirements and postpones nonfunctional requirements and implementation specific issues until subsequent design activities are undertaken. Based on the analysis models, the design activities are performed by refining and clarifying the analysis models. Thus, the quality of analysis models has a vast impact on the design models. Therefore, much effort should be taken to build correct analysis model. In this paper, we propose a set of structural constraints that analysis models of typical object-oriented development methods should satisfy. Three kinds of constraints are proposed: class related constraints, relation related constraints, and usage related constraints. For each constraint, formal definition and description with OCL are provided. In addition, through a case study with two medium-sired industrial systems, we demonstrated that the proposed approach can help to identify and correct serious deficiencies in object-oriented analysis models.

  • After reviewing the background and motivations for using modern computational methods for the design of reinforced concrete structures, an algorithm making use of the object oriented programming language Python and professionally developed finite element software is presented for the sizing and placement of the reinforcement in RC structures. The developed method is then used to design the reinforcement of a deep beam. To validate the design, two identical deep beam specimens were manufactured with the obtained steel, and then tested in the laboratory. It was found that the experimental results corroborated those predicted with the finite element design method.

  • My proposed Co-creation platform software analysis and design method in my paper, presents build technology of co-creation platform using Co-creation concepts refer to all process from products' idea level to products' design, manufacturing and marketing level. And this method can be possible to design and implement to be interlocked with company's cloud service and system through own SNS functions and OPEN API to build co-creation platform. Also owing to apply Wiki technology in the process of idea modification and completion level and provide cooperative work tools of story-board prototyping, it can be participate actively in the design process with customer and stakeholder together and realize functions to apply opinions. Therefore, Co-creation platform software analysis and design by objected-oriented analysis method is presented to show these design process effectively.

  • Object orientation has become the predominant paradigm for conceptual modeling (e.g., UML), where the notions of class and object form the primitive building blocks of thought. Classes act as templates for objects that have attributes and methods (actions). The modeled systems are not even necessarily software systems: They can be human and artificial systems of many different kinds (e.g., teaching and learning systems). The UML class diagram is described as a central component of model-driven software development. It is the most common diagram in object-oriented models and used to model the static design view of a system. Objects both carry data and execute actions. According to some authorities in modeling, a certain degree of difficulty exists in understanding the semantics of these notions in UML class diagrams. Some researchers claim class diagrams have limited use for conceptual analysis and that they are best used for logical design. Performing conceptual analysis should not concern the ways facts are grouped into structures. Whether a fact will end up in the design as an attribute is not a conceptual issue. UML leads to drilling down into physical design details (e.g., private/public attributes, encapsulated operations, and navigating direction of an association). This paper is a venture to further the understanding of object-orientated concepts as exemplified in UML with the aim of developing a broad comprehension of conceptual modeling fundamentals. Thinging machine (TM) modeling is a new modeling language employed in such an undertaking. TM modeling interlaces structure (components) and actionality where actions infiltrate the attributes as much as the classes. Although space limitations affect some aspects of the class diagram, the concluding assessment of this study reveals the class description is a kind of shorthand for a richer sematic TM construct.

  • Statistics concerning software errors indicate that more errors are introduced in analysis and design phase than implementation phase. Therefore, it is needed to check whether the design modeling is appropriate for own function and structure. This paper discussed the effective test method for the object-oriented design model, i.e., UML. A new method was proposed for generating test data. This method consists of category partition theory by the representation each element in UML model with OCL (Object Constraint Language). Test data generated in this way can be used for testing the source code functionality as well as for checking the design model.
