-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
Ⅰ. 초고속 엘리베이터 시장에 대해서
1) 특 징
초고속승강기는 보통 분당 이동속도가 150m를 넘는 승강기종을 지칭하는데 수량기준으로 국내 엘리베이터시장의 3%에 불과하지만, 대당 설치가격이 아파트용 저속기종에 비해 최고 10∼20배에 달하는 고부가가치 제품인데다 기술력 과시를 통한
Mechanical stability when standing is based on musculo-skeletal linkages between the trunk and legs.
Dynamic equilibrium during walking is maintained by coordinated synergies of axial and proximal limb contractions and a hierarchy of postural reflexes and reponses.
Supraspinal centers signal when to start walking, when to stop, the speed of locomotion, and the size and direction of stepping.
C
direction, inlet locates downside and outlet locates upside.
Through this, we can know that axial impeller is not suitable. Also, because of wide width of tank, it has poor mixing.
Second, there is a problem with chemicals. PAC is injected with Cl2, so activation of Cl2 must be restricted.
Also, using alum may cause settling.
Alum lowered pH in localized area. To overcome this problem, we
