Good localization result is obtained from rough RF information.(b)Step 2: Finally, a shearing load is added to the moving plate A thin plate is fabricated in this step.The tensile strength of the Ti thin plate formed by the Compression Shearing Method at Room Temperature (COSME-RT) was found to be 3 times larger than that for the rolled Ti.Compression Shearing Method at Room Temperature (COSME-RT): (a)Step 1: metal powder is first placed between a stationary plate and a moving plate in the apparatus. A compressive stress is then applied to the moving plate and maintained during the forming process. and displaced in the shearing direction.Jun-yaTakayamaAssociateProfessorHehasbeenafacultyatShinshuUniversitysince2012.Hiscurrentresearchinterestsaretheintelligentsensingsystemsandthehigh-accuracysensingtechniquesrelatingthem.Noboru NakayamaAssociateProfessorDr.Eng.Researcharea:Plasticworking(powdermetallurgy),NondestructiveinspectionIn the FutureAfter GraduationIn the FutureAfter GraduationEngineeringEngineering3 timesRealization of Intelligent Sensing Systemsthat can think about their Own PerformanceDevelopment of Materials Useful in the Fields of Medicine and Welfare
