모바일 가상화는 두 개의 가상 플랫폼을 하나의 무선 장치에 탑재하는 모바일 장치 관리의 한 접근 방법이다. 단일 무선 장치인 스마트폰은 사업용과 개인용으로의 가상 환경으로 사용될 수 있을 것이다. 모바일 가상화는 또한 동일한 장치에 두 개의 운영체제인 RTOS와 안드로이드 앱이 동시에 수행되는 환경일 수 있다. 본 논문에서는 멀티코아에서 각 코아를 가상화하고, 물리 CPU(pCPUs)에 배당된 여러 가상 CPU(vCPU)를 재 할당하는 기법을 제시하며 또한 가상 CPU들을 물리 CPU에 할당하기 위한 실시간 스케줄링 방법을 제안한다. 본 논문에서 제안된 기술은 인터럽트 처리시에 실시간 처리의 시간 지연을 해결하였고, 이전의 알고리즘보다 빠른 처리를 가능하게 한다. Mobile virtualization is an approach to mobile device management in which two virtual platforms are installed on a single wireless device. A smartphone, a single wireless device, might have one virtual environment for business use and one for personal use. Mobile virtualization might also allow one device to run two different operating systems, allowing the same phone to run both RTOS and Android apps. In this paper, we propose the techniques to virtualize the cores of a multicore, allowing the reassign any number of vCPUs that are exposed to a OS to any subset of the pCPUs. And then we also propose the real-time scheduling method to assigning the vCPUs to the pCPU. Suggested technology in this paper solves problem that increases time of real-time process when interrupt are handled, and is able more to fast processing than previous algorithm.

Even though 12Cr alloy steel can be different in alloy composition and crystal structure according to the manufactures, it was found that more than 60% of damages were occurred at the condition alternatively repeated wet and dry and condensed vapor at low pressure. And also, it has been well known that both the mechanical properties and the influence of corrosion environments on strength of the 12Cr alloy steel change by its crystal structure. However, in spite of these common facts, it is difficult to find out the quantitative results including the particular environmental condition as well as the actual service conditions. In this study, as a fundamental investigation for providing information to design and to asses integrity of the 12Cr alloy steel, electro-chemical corrosion susceptibility and corrosion rate of the steam turbine bucket material of which its grain size is different was assessed under NaCl solution at 90℃.

However, in spite of these common facts, it is difficult to find out the quantitative results including the particular environmental condition as well as the actual service conditions. In this study, as a fundamental investigation for providing information to design and to asses reliability of the 12Cr alloy steel, stress corrosion cracking of the 12Cr alloy steel of which its crystal structure is different was assessed under 2.5~3.5wt.% NaCl solution at 90℃. From these results, S-t curves for predicting damage life and design criterion of the 12Cr alloy steel including corrosion environment as well as S.C.C. condition were obtained.
