In Line Heating method, heating line is determined by kinematics analysis. But the heating line, which is solved by kinematics analysis, doesn't verify by the point of physical analysis and the choice problem in many heating line doesn't determine. In this paper, the simulator is developed. When we get the processing information at the kinematics analysis, simulator can estimate the shape of deformed plate that process along the processing information. When we get the initial shape and the object shape, we calculate the processing information first, using kinematics analysis. In a simulator, we estimate deformed shape from the processing information. After this we compare deformed shape and object shape. If the error of deformed shape and object shape is in the proper limits, that information is determined the final processing information. Else we repeat the process changing variables.

The major purpose of this study is to explore the effect of the presentation undo combined by main four media(moving Image, audio, turf image) of web contents on the children's information processing process. So children were assigned to one of five experimental medium conditions: 'moving Image1 (auditory-visual redundancy)', 'moving Image2 (auditory-visual dissonance)', 'text', 'text-with-image', 'audio'. Results indicated that the moving image was found to be the most effective transmitter of internet news information for children's recall. And the recall advantage of moving image was found to be particularly pronounced for verbal information supplemented with redundant visual.

Re-manufacturing is the process of recovering the function and performance of the original product through a re-assembly process such as a new product assembly process after reprocessing by recovering used products or parts that are in the disposal stage at the end of their lifespan. One of the manufacturing methods. The remanufacturing industry is important not only in terms of environmental protection, but also in terms of economics. The success or failure of the industry as a whole depends on trust in products and price competitiveness. Image processing systems are used to reduce labor costs and improve product reliability in the product manufacturing process. In this study, foreign substances and defects that are difficult to identify with the human eye are detected by using the pre-processing step of determining whether to recycle the drum and image processing immediately before shipment after regenerating the drum to regenerate the waste drum.

EPDW는 Event-Process-Data-Work의 약자로 소프트웨어 아키텍처이다. 이 아키텍처는 Event 지향적인 프로그래밍 아키텍처이다. Event 가 발생하면 Process에서 가공하고 Data로 만들어 Work가 처리하는 기본구조를 가지고 있다. 모든 Event는 EventDivider 흐름이 관리되며 Process는 EventDivider에 등록된다. Work는 하나의 기능단위로써 필요한 controller들과 Process들을 가진다. 이를 통해 Event 가공의 코드의 재사용 및 분산방지가 된다. 그리고 Event 흐름의 단순화와 추적의 용이성을 증대해 디버깅에 이점을 가진다.

소프트웨어 개발 프로젝트의 특성을 고려한 프로세스의 테일러링은 고품질 소프트웨어 개발에 기본적인 요건이다. 테일러링을 유연하게 하기 위해서는 프로세스 구성 변화에 대한 영향이 지역화 되도록 프로세스 구성요소가 모듈화되어야 한다. 본 논문에서는 프로세스 모델을 모듈화된 요소기반으로 정의하기 위한 메타모델을 정의한다. 또한 정의된 메타모델을 기반으로 모듈화된 프로세스 모델의 예를 제시한다.

소프트웨어 제품 및 서비스의 품질 향상을 위한 방법으로 개발 프로세스의 개선을 목적으로 시작된 SPA & SPI(Software Process Assessment & Software Process Improvement)가 그 효과와 필요성을 인정받고 국내에서도 서서히 기업에 널리 확산되는 추세이다. 하지만 기업 문화의 차이와 시간적, 공간적, 비용적 이유로 SPA의 확산 및 수행에 어려움이 있다. 본 논문에서는 SPA에 GDSS(Group Decision Support System)를 적용하여 좀 더 원활하게 수행하고자 ISO/IEC TR 15504를 모델로 하는 심사 도구의 개발을 위한 연구를 하였다.

The LiDAR sensor is attracting attention as a key sensor for autonomous driving vehicle. LiDAR sensor provides measured three-dimensional lengths within range using LASER. However, as much data is provided to the external system, it is difficult to process such data in an external system or processor of the vehicle. To resolve these issues, we develop integrated processing system for LiDAR sensor. The system is configured that client receives data from LiDAR sensor and processes data, server gathers data from clients and transmits integrated data in real-time. The test was carried out to ensure real-time processing of the system by changing the data acquisition, processing method and process driving method of process. As a result of the experiment, when receiving data from four LiDAR sensors, client and server process was operated using background or multi-core processing, the system response time of each client was about 13.2 ms and the server was about 12.6 ms.

This paper presents an integrated and automated inspection system using image processing technology for the automotive engine assembly process. The system make it possible for the inspected data to be entered directly from the machine vision into the statistical process control system. Such direct entry enables the prompt preparation of corrective actions against process problems. An IVP-150 machine vision board is installed within the PC for image processing, and a template matching technology is implemented to precisely verify quality factors. The developed system showed robustness to the problems of noise, distortion, and orientation.

Providing web services to users has become expensive in recent times. For better web services, a web server is provided with high-performance technology. To achieve great web service experiences, tools such as general-purpose graphics processing units (GPGPUs), artificial intelligence, high-performance computing, and three-dimensional simulation are widely used. However, graphics processing units (GPUs) are used in high-speed operations and have limited general applications. In this study, we developed a task queue in a GPU to improve the performance of a web service using a multiprocessor and studied how to receive and process user requests in bulk. We propose the use of a GPGPU-based task queue to process user requests more than GPGPU based a central processing unit thread, and to process more GPU threads on task queue at about 136% to 233%, and proved that the proposed method is effective for web service.
