BASED on vast experience watching the fruit of my hard work fall apart time and again, I feel highly qualified to discuss the manner in which systems break. In particular, the goal of this paper is to define and analyze systems which exhibit brittle behavior. This behavior is characterized by a sudden and steep decline in performance as system state changes as shown by point D along curve Ph in...

Abstract This paper elucidates a method of actuation and feedback for hard-soft composite continuum pentapod appendages to enable both kinematic accuracy gait. A mechanism based on Hall effect sensors is integrated within hard exterior/soft interior robotic limb, which unaffected by actuator slippage, provides accurate (sub 2°) end point measurements. The proposed uses two actuators control ful...

This study set out to evaluate the wound healing properties of brittle star extracts in vitro and vivo. Due great arm regeneration potential star, Ophiocoma cynthiae, present aimed effect hydroalcoholic undergoing models. The samples were collected from Nayband Bay, Bushehr, Iran. After induction stars, relating different times prepared. GC-MS analysis, MTT cell viability migration, Western blo...
