Introduction: Flexures are low-cost bearings that are capable of providing motion guidance with high repeatability and low friction (Figure 1). However, applications of flexure bearings are often limited by their low range. This is because motion guidance in flexures is provided by ... Saiba Mais

Design of Multiple Ground System for Maternal Defibrillation new

A. Jeremic[1], E. Khoshrowshahli[2]
[1]Electrical & Computer Engineering, McMaster University, Hamilton, ON, Canada
[2]Biomedical Engineering, McMaster University, Hamilton, ON, Canada

Although cardiac arrest may be statistically insignificant event financial and more important emotional costs in such cases are quite devastating. In this paper we study the effects of multiple grounding pads. Namely, we believe that by placing multiple pads in the lower abdominal ... Saiba Mais

2차원 및 3차원 맨틀 플룸의 벤치마크

Y. Kim, C. Lee [1]
[1] Department of Earth and Environmental Sciences, Chonnam National University, South Korea

최근의 수치모델링 연구들은 맨틀 플룸(mantle plume)이 배호(back-arc)지역의 분지 및 산맥(basin and range)과 유사한 지구조를 형성시키는 성인임을 제시하였다. 섭입 슬랩 후퇴(slab roll-back) 현상에 의해 지각에 가해지는 인장력과 지각 아래로부터 상승하는 뜨거운 맨틀 플룸으로 인한 지각 강도 감소가 더해져 배호 지역에 분지를 형성시킨다는 것이다. 이처럼 분지 형성 작용에 있어 맨틀 플룸의 역할이 중요해짐에 따라, 수치모델링의 필요성이 커지고 있기 때문에 초기 연구로써 ...

The Spherical Design Algorithm in the Numerical Simulation of Fiber-Reinforced Biological Tissues

M. Carfagna [1], A. Grillo [1],
[1] Dipartimento di Scienze Matematiche, Politecnico di Torino, Italy

The numerical results of the unconfined compression test on a sample of Articular Cartilage (AC) are discussed. AC is modelled as a load-bearing, deformable, fiber-reinforced material filled with an interstitial fluid and comprising statistically oriented collagen fibers, chondrocytes, ... Saiba Mais

Dynamic Saturation of TiZrV Layer of Non-Evaporable Getters (NEG) Chamber

M. Ortino [1], J. A. Ferreira Somoza [1], G. Bregliozzi [1]
[1] CERN, Geneva, Switzerland

Non-evaporable getters (NEG) chambers are 316L vacuum chambers coated with a TiZrV layer, widely used in accelerator systems. This particular alloy works, when thermally activated, as a linear pump for almost all gas species inside the chamber: molecules are adsorbed on the surface or ... Saiba Mais
