Estimating Taxonomic Diversity Using Centrum Growth Profiles and Stinger Morphology of 36 Million Year Old Stingrays From North Dakota
… by their individual vertebral centra, stingers, and teeth. No complete specimens have been identified. We examined 36 isolated vertebral centra and estimated the number of growth cessation marks on each centrum. Centrum radial distance (mm) was measured from the notochord foramen to …

Análise estrutural de dutos submarinos durante a operação de lançamento
… existing others. The influence of tension, stinger curvature and spring coefficients of the ocean floor are also studied.

Human factors and telerobotics : tools and approaches for designing remote robotic workstation displays
… of two 7 DOF arms, two 12 DOF hands, a 6+ DOF "stinger tail", and a 2+ DOF stereo camera platform. Current robotic workstations are insufficient for controlling highly dexterous manipulators, which require full immersion operator telepresence. The Robonaut workstation must be designed to allow …

Examination of the application and limitations of structural mode extraction via force apportionment
… The interaction of the electrodynamic shaker, stinger, and force transducer with the structure is investigated as a possible explanation for the failure of the technique in experimentation. It is found that there exists axial and rotatory coupling which can influence the structural response of …

Analysis of Force-Limiting Capabilities of Football Neck Collars
… Transient brachial plexopathy, commonly called a stinger or burner, is an injury to the brachial plexus. As many as 65% of collegiate football players will receive suffer such an injury. Accessory neck collars are worn to mitigate the risk of stingers, although little research has been performed …

The Design of Complex Weapons Systems in Scorpions: Sexual, Ontogenetic, and Interspecific Variation
… system consisting of a tail-like metasoma with a stinger at the tip of the terminal segment (telson) that can be thrust into prey, predators, or mates to inject venom. Given the complexity of these systems, I hypothesized that weaponry design is subject to selective forces arising from differences …

Impact Biomechanics of the Head and Neck in Football
… in this thesis related to the neck is based on stingers. Football players wear neck collars to prevent stingers; however, their designs are largely based on empirical data, with little biomechanical testing. The load limiting capabilities of various neck collars were investigated through dynamic …
