Development of a Machine Vision System for Automotive Part-Car Seat Frame Inspection
Nelson S. Andres(Nelson S. Andres),장봉춘(Jang Bong-Choon) 한국자동차공학회 2005 한국자동차공학회 지부 학술대회 논문집 Vol.- No.-
Meeting the growing demand deadlines, reducing the production cost and upgrading the quality control measurements are the reasons why the automotive part manufacturers are venturing into automation. Attaining these objectives is impossible with human inspection for many reasons. Accordingly, the introduction of machine vision system purposely for car seat frame inspection is presented in this study as an alternative for human inspection. This proposal is designed to meet the demands, features and specifications of car seat frame manufacturing companies in striving for increased throughput of better quality. More specifically, this computer-based inspection proposal is designed to perform quality measures to detect holes, nuts and welding spots on every car seat fiame in real time and ensuring these portions to be intact, precise and in proper place. In this study, the NI Vision Builder software for Automatic Inspection is used as a solution in configuring the aimed quality measurements. These quality measurement techniques for visual inspection are optimized through qualitative analysis and simulation of human tolerance on inspecting car seat frames. Furthermore, this study exemplifies the incorporation of the optimized vision inspection environment to the pre-inspection and post-inspection phases using LabVIEW software.

Objectives: The purpose of this paper is to describe the role for public education in mental health promotion, prevention of mental illness and treatment of mental disorders in Canada. Results: A brief history of the changing nature of the way we treat mental disorders in Canada argues for an increasingly critical role for public education. Furthermore, the new understanding of the role of social determinants in prevention of mental illness again necessitates a vital role for public education as the shift in focus moves from exclusively individual-focused health care treatments to creating supportive environments. The roles for mental health public education then become: advocacy for the social determinants of health approach, better understanding of the nature of mental health problems, useful information for self-management, and more knowledge about appropriate treatments. A brief discussion of the structure of the response in Canada provides an overview of national and provincial responsibilities in mental health care with a case study highlighting one community's response to addressing mental disorders. Conclusion : Finally, challenges regarding the most effective educators and the issue of professional expertise embedded in the status quo are discussed.

산업디자인은 과학기술이 발달한 나라에서 행하여지는 새로운 종류의 전문적인 활동으로, 현재 미국이나 영국, 일본과 그 밖의 서구라파의 몇몇 나라에서 성행하고 있다. 새로운 예술인 산업디자인은 고도로 발달된 산업과 직접적인 관계를 갖기 때문에 불가사의하고 생소하게 여겨질지도 모른다. 그러므로 산업디자인을 논하는 데 있어서의 첫 번째 단계는 그 불가사의한 점을 밝혀내는 것이라 하겠다. 그러기 위해서는 디자인과 공업과의 직접적인 관계를 잠시 제쳐놓고 디자인에 관한 문제를 인간의 기본적인 활동으로 생각해 보면 된다.
Lubrication Aspects during Single Point Incremental Forming for Steel and Aluminum Materials
Nelson Gil Azevedo,João Sá Farias,Ricardo Pereira Bastos,Pedro Teixeira,João Paulo Davim,Ricardo Jose Alves de Sousa 한국정밀공학회 2015 International Journal of Precision Engineering and Vol. No.
Over the past few years, Single Point Incremental Forming (SPIF) has been mainly studied regarding formability, forming forcesinvolved and the dimensional accuracy achieved in the final product. As in any other metal forming process, the choice of thelubricant depends on the deformation mechanisms that characterize the process, the roughness of the material involved and on theprocess parameters. Despite the recent developments on SPIF, little attention has been paid to the influence of lubricants used duringthe process. This study intends to evaluate the influence of the type of lubricant used in SPIF process, particularly on aluminum 1050and DP780 steel sheets, in what concerns the surface quality of final parts. To do so, tests were performed employing a range ofdistinct lubricants. Roughness tests were conducted to evaluate surface quality. Results show opposite trends for aluminum and steelin the sense that lubricants that guarantee better results in aluminum proved to have worse results in steel and vice-versa.

Hundreds of years ago the prophet Isaiah said that we should no longer look backward, but rather look forward because God is doing a new thing(Isa. 43:19)! Since then God has done and continues to do many new things. This is especially true in reference to the evangelization of the world. No longer do Christians see this as the sole responsibility of Western Christians, but realize that the Great Commission applies equally to men and women of every continent, nation and trebe.
