  • Hybrid robust image processing algorithm to extract visual features of melon during the cultivation was developed based on a wireless tele-operative interface. Features of a melon such as size and shape including position were crucial to successful task automation and future development of cultivation data base. An algorithm was developed based on the concept of hybrid decision-making which shares a task between the computer and the operator utilizing man-computer interactive interface. A hybrid decision-making system was composed of three modules such as wireless image transmission, task specification and identification, and man-computer interface modules. Computing burden and the instability of the image processing results caused by the variation of illumination and the complexity of the environment caused by the irregular stem and shapes of leaves and shades were overcome using the proposed algorithm. With utilizing operator's teaching via LCD touch screen of the display monitor, the complexity and instability of the melon identification process has been avoided. Hough transform was modified for the image obtained from the locally specified window to extract the geometric shape and position of the melon. It took less than 200 milliseconds processing time.

  • The UCA is a standard-based approach to utility communications which provides for wide scale integration of functional areas including customer interface, distribution, transmission, power plant, control center, and corporate information systems. Field devices in the power facilities require real-time communications, and they must be interconnected into fieldbus. This study introduces a method of implementing gateway that interfaces UCA and fieldbus. In this study, PROFIBUS and FOUNDATION Fieldbus are selected as candidate fieldbus protocols. Protocol interface in the gateway can be accomplished by mapping objects and services of UCA and fieldbus. MOst of the UCAs CASM objects and services are directly mapped into those of the application and user layers of fieldbus. However, some CASM services are not supported in the application and user layers of fieldbus. This study presents the method of implementing those services. In order to show that the implementation of interface is possible, this study presents pseudo-codes of interface program that maps the objects and services of UCA and fieldbus.

  • 현재 교량과 같은 토목구조물의 설계프로세스는 1차 설계 후 구조 검토를 수행하여 기준에 부적합할 경우 재설계하는 과정을 반복하여 최종적인 성과품을 만드는 것이 일반적이다. 이러한 반복 과정은 설계에 소요되는 기간을 연장시키는 원인이 되며, 보다 수준 높은 설계를 위해 투입되어야 할 고급 엔지니어링 인력을 기계적인 단순 반복 작업에 소모하고 있다. 이러한 문제는 설계 과정 자동화를 통하여 해결할 수 있으나, 설계 과정에서 사용되는 해석프로그램은 이러한 자동화에 가장 큰 장애요인이 되어 왔다. 본 연구에서는 기존 설계 과정 중 반복작업을 대체하고자 강화학습 알고리즘과 외부 해석프로그램을 함께 제어할 수 있는 인터페이스를 포함한 교량설계 프로세스에 대한 AI기반 자동화 시스템을 구축하였다. 이 연구를 통하여 구축된 시스템의 프로토타입은 2경간 RC라멘교를 대상으로 제작하였다. 개발된 인터페이스 체계는 향후 최신 AI 및 타 형식의 교량설계 간 연계를 위한 기초기술로써 활용될 수 있을 것으로 판단된다.

  • In this paper, an automated design system of suspension and steering parts is developed. The system automates the processes of 3-D modeling and 2-D drafting of the parts. In addition, the BOM and dimension data of the designed part is also automatically transferred to the database of ERP system. The system is developed by using the functions of parametric design and API(application Programming Interface) of the a commercial solid modeler.

  • It is said that the verification effort occupies about 50-70 percent of the total effort of a System-On-A-Chip. This paper aims to develop a test bench automation tool based on the abstraction of the interface protocols. This tool will allow designers to describe their test benches in a high level language such as C rather than VHDL or Verilog. It helps designers to save their verification time and effort.

  • Phenomelocial evidences for three-dimensional crystallizing $\pi$-bondings are investigated in case of the soft layer very near the suface of the metal , the surface layer of certain crystaline thermoplastics. the increased contact area of the metalic frictional interface and the delaminated sheet-like wear particles of the metal . The wear mechanisms are the cracks at the boundaries of the grains and their propagations parallel to the surface. The cracks are made by the reorientations of the atoms in the grains and the rotations of the grains.

  • An early step toward evaluating a predicted RNA secondary structure is to visualize the predicted structure in graphical form. This talk will present an algorithm for efficiently drawing RNA secondary structures. The algorithm represents the direction and space for a structural element using vector and vector space, and generates nearly overlap-free polygonal displays. The algorithm and a graphical user interface have been implemented in a working program called VizQFolder on IBM PC compatibles.
