동역학 제어 실험 과제
1. 임펄스 테스트
FEM이나 전달 행렬 방법으로 모델링 한 회전축을 실험적으로 검증하기 위해서 임펄스 테스트를 수행한다. 베어링이 없는 축을 매달고 매단 방향과 직각으로 가속도계를 축에 붙이고 축을 임팩트 해머로 때려 그 둘 사이의 주파수 응답을 구한다. 이러한 주파
I Introduction
1) Purpose of project
Our purpose of this project is to use the knowledge we learned in the statistics management class and understand how to use these information to analyse the data we collected and depending our data to find the relationship between 3 variables we choose for proving the hypotheses we bring up are correct or not. Statisitics is a very important concept to many
Based on the data we found on the annual report and detailed product report of the company, we found out that a person can assemble 13 big LCDs in a day if they work for 10 hours. Therefore, from 13/10 we get 1.3 LCD per hour, and in order to fix this into labor hours per assembly, we divided 1 with 1.3 and got 0.77.
Labor hours per testing: 0.5
Since Labor hours for testing was recor
Testing은 spirogram이라는 다음과 같은 그래프를 나타낸다.
: volume-time curve, Y축에 volume(liters), X축에 시간(seconds)
: flow-volume loop, Y축에 rate of airflow, X축에 total volume of expiration or inspiration
G. Calibration and quality control
Spirometer의 quality control은 calibration과 매우 밀접한 연관이 있다. calibration은 quality control을 위

Gibbs/Duhem식은 체계적인 오차를 포함하는 실험값들이 만족시키지 못할 가능성이 있는 제한 조건을 활동도 계수에 부과한다. 이런 경우에 Gibbs/Duhem 식에 의존하지 않는 식

Why we chose this subject ?
Obviously there are many people using SNS,
and every year more people jump into SNS world.
Many Facebook pages about tourism post tour sites information and some other things about tourism a lot.
And there are many blogs related to tourism in some websites
such as Naver, Daum, etc.
At this point, we wanted to figure out if SNS has something to a
I. 서론
Blood Pressure
Figure 1-1 : 혈액이 혈관에 작용하는 혈압을 보여주고 있습니다.
혈관계 회로에서 심장박동의 펌프작용으로 박출된 혈액에 의해서 혈관벽(특히 동맥)에 생기는 압력. 심장에서 혈액이 박출될 때 약간 탄력성을 갖는 혈관벽이 조금 넓어지고 동시에 혈액은 혈관벽에 대한 혈
testing it by regression analysis, few variables had eliminated. Among the economic variables we added at the beginning, the labor participation is the only left one. The final model indicated that economic variables do not fully explain the high ration of suicide in Korea.
Therefore, the suicide rate in Korea has more association in aging society or divorce rate rather than labor participation
Depending on the organization, and depending on the industry the organization belongs to, an organization will have its unique culture that is different from others. Many factors about the organizations will influence it to adopt a certain organization. When talking about companies and its culture, Microsoft is almost always mentioned as the organization with an individualistic culture. To learn
