압축비는 내연기관의 열효율을 결정하는 중요한 parameter이다. 이상적인 Otto cycle의 열효율의 식은 다음과 같이 표현된다.
( : thermal efficiency, : compression ratio, : specific heat ratio)
이때 비열비 는 공기에 대해 1.4 정도로 일
compression of probability of default (PD) estimates in internal ratings-based (IRB) capital requirements during benign credit conditions by using the PD estimates for a bank’s portfolios in downturn conditions. Addressing the same issue, the UK Financial Services Authority (FSA) has proposed an approach aimed at providing non-cyclical PDs in IRB requirements through the application of a scala
-Conclusion & Discussion
Poisson's ratio is derived by dividing the horizontal strain modulus by perpendicular strain modulus. Poisson's ratio is a characteristic value of materials, and concretes have 0.16∼0.22 of it. The Poisson's ratio from the first experiment is 0.18 and this is comprised in the range of theory, and the value from the second experiment is 0.16 which also comes under th
