Arboreal animals with prehensile hands must balance the complex demands of bone strength, grasping and manipulation. An informative example of this problem is that of the aye-aye (Daubentonia madagascariensis), a rare lemuriform primate that is unusual in having exceptionally long, gracile fingers specialized for foraging. In addition, they are among the largest primates to engage in head-first...

The noise and vibration of a ring-plate pincycloid gear reducer driven by two motors are measured respectively at different rotational speeds and different loads. The data are collected and analyzed using the HEAD acoustics multi-channel noise test and analysis system. The ArtemiS is a set of analysis system for improving product quality in all areas of sound and vibration. From the frequency s...

The combination of functional MR imaging and novel robotic tools may provide unique opportunities to probe the neural systems underlying motor control and learning. Here, we describe the design and validation of a MR-compatible, 1 degree-of-freedom pneumatic manipulandum along with experiments demonstrating its safety and efficacy. We first validated the robot's ability to apply computer-contro...

Issues related to the design and hydraulic calculations of transit part a closed tubular water supply structure siphon type are considered. The operating conditions with rectangular pipes in transition mode estimated. Due formation jump, inlet section experiences increased hydrodynamic loads, leading certain defects destruction. two breaks along length portal smooth head or without it was model...

Helmet-mounted systems (HMS), such as night vision goggles and helmet-mounted displays, are designed to enhance pilot performance. Using HMS, however, may also affect pilot safety by increasing the potential for neck injury during ejection due to the increase in dynamic forces generated in the cervical spine as a result of the change in helmet inertial properties. Pilot bracing techniques may a...

The success that banks have had deploying remote deposit capture has been tremendous over the past few years. The ability to decrease manual handling of checks and increases deposit breadth has certainly been a positive in what otherwise has not been the greatest of times in the banking community. However, as with any success along comes scrutiny. Echoes from the halls of Congress of not enough...

Production of nursery crops in the US is accomplished in containerand field-growing conditions, with propagation and seedling-rearing carried out in greenhouses; 11% of the US national farm-product is represented by these crops. Container-grown crops represent 60% of the US market and represent a highly labor-intensive and thus costly segment of ornamental crop production. The USDA, NASA and th...

Recent years have seen an increasing awareness of the anatomical and biomechanical significance of the distal radioulnar joint (DRUJ). With this has come a more critical approach to surgical management of DRUJ disorders and a realization that all forms of "excision arthroplasty" can only restore forearm rotation at the expense of forearm stability. This, in turn, has led to renewed interest in ...

Mosaic evolution is a key mechanism that promotes robustness and evolvability in living beings. For the human head, to have a modular organization would imply that each phenotypic module could grow and function semi-independently. Delimiting the boundaries of head modules, and even assessing their existence, is essential to understand human evolution. Here we provide the first study of the huma...

This paper focuses on the investigation carried out on the failure of the MSC Napoli using two-dimensional (2D) symmetric (i.e. vertical bending) hydroelasticity analysis. The aim of the investigation was to assess the influence of whipping-induced loads on the structural strength of this containership. Relevant structural, hydrostatic and operational data were provided. The calculations were c...
