PURPOSE This study evaluated different fibular-based reconstruction techniques for grade III posterolateral corner (PLC) injuries. METHODS Seven fresh-frozen cadaveric knees were used in this study. A surgical navigation system was used to determine varus opening and external rotation at 0 degrees , 30 degrees , and 60 degrees with a 9.8-Nm varus stress and 5-Nm external rotation stress appli...

When magnetic tunnel junctions (MTJ) are built into a memory device they will be arranged in a matrix; therefore some of the not addressed elements will be exposed to a significant field during the switching of one element. It has to be avoided that the state of not selected MTJ is changed during this process. Here we present data on the stability of MTJ against small fields which occur during ...

This paper presents a genetic algorithm for automating the design process for underground tunnels. The tunnel cross-sectional profile must enclose a prescribed minimum space polygon, and for stability the bending moments in the shotcrete lining must not exceed certain limits. The engineer seeks to achieve these aims while minimizing the volume of rock to be excavated. We describe the five param...

Nowadays, numerical modelling is increasingly used to assess the stability of tunnels and underground caverns. However, an analysis of the mechanical behaviour of existing brick-lined tunnels remains challenging due to the complex material components. In order to study the mechanical behaviour of the masonry in brick-lined tunnels, this paper proposes a series of small scale physical tunnel mod...

The excavation of deep tunnels has significant spatial and temporal effects on the stress distribution surrounding rock. Accurately describing characteristics rock state is a key issue in analyzing failure mechanism Based numerical analysis, study influencing factors during was conducted. results show that (i) divided into mutation, disturbed, stables zones using quantitative index: peak stable...
