This paper introduces jumping robots as a means to traverse rough terrain; such terrain can pose problems for traditional wheeled, tracked and legged designs. The diversity of jumping mechanisms found in nature is explored to support the theory that jumping is a desirable ability for a robot locomotion system to incorporate, and then the size-related constraints are determined from first princi...

Nordic ski-jumping fatalities are rare events. Six jumping fatalities have occurred in the United States during the past 50 years. The fatality rate for nordic ski jumping, estimated to be roughly 12 fatalities/100,000 participants annually, appears to be within the range of fatality rates for other "risky" outdoor sports. Cervical fractures appear to be the most frequent fatal ski-jumping injury.

Because of inherent variability in all human cyclical movements, such as walking, running and jumping, data collected across a single cycle might be atypical and potentially unable to represent an individual's generalized performance. The study described here was designed to determine the number of successive cycles due to continuous, repetitive countermovement jumping which a test subject shou...

Conclusion Jumping of legged mobile robots has been a highly motivated research area. When a running robot encounters obstacles comparable to its body height, jumping is one of the most effective ways to overcome them. Also, if the robots can jump over gaps or crevices, the mobility of robots in a wild field would be enhanced drastically.The jumping performance is dependent on the terrain prope...

introduction: morphine withdrawal syndrome is mediated via several central and peripheral neurological pathways. in the present study we investigated the role of n-methyl-d aspartic acid (nmda) glutamate receptor on naloxone-induced withdrawal syndrome in morphine-conditioned mice. materials and methods: we designed two separate experiments. in experiment one, 30 male nmri mice were divided int...

Frogs are characterized by a morphology that has been suggested to be related to their unique jumping specialization. Yet, the functional demands associated with jumping and swimming may not be that different as suggested by studies with semi-aquatic frogs. Here, we explore whether features previously identified as indicative of good burst swimming performance also predict jumping performance i...

This paper presents a review of recent jumpingrobots including the following; the NASA JPLHopper, the Sandia National Laboratories Hopper,the University of Michigan Monopod Jumper,Kagoshima University Pendulum JumpingMachine, Tokyo Institute of Technology Air-hopper, University of Minnesota Scout robot, CaseWestern Reserve University Jumping MiniWhegsTM, and the ...

Objectives: New cognitive theories of delusions have proposed that deficit or bias in inference stage (a stage of normal belief formation) is significant in delusion formation. The aim of this study was predicting the severity of delusions based on jumping-to-conclusion bias in patients with schizophrenia. Methods: The sample consisted of 60 deluded patients with schizophrenia w...

coordination, body and limb designs are related to the environmental objects and events. the aim of this study was to investigate the necessity to implement rope jumping program in iran schools and since one of the major problems in learning how to write is eye–hand coordination, the effect of a rope jumping training course on eye–hand coordination was investigated in the fourth grade elementar...
