1987 ecosystem view of management research in the Myakka River: review of Phase I and Phase II reports

This memorandum has four parts. The first is a review and partial synthesis of Phase 1 and Phase 2 Reports by Dr. Ernest Estevez of the Mote Marine Laboratory to the Board of County Commissioners of Sarasota County, Florida. The review and synthesis emphasizes identification of the most important aspects of the structure of the Myakka system in terms of forcing functions, biological components, and major energy flows. In this context, the dominant primary producers, dominant fish species and food habits, and major environmental variables were of articular interest. A major focus of the review and synthesis was on the river zonations provided in the report and based on salinity and various biological indicators. The second part of this memorandum is a review of a draft report by Mote Marine Laboratory on evaluation of potential water quality impacts on the Myakka River from proposed activities in the watershed. This Memorandum's third part is a review of resource-management related ecosystem models in the context of possible future models of the Myakka River Ecosystem. The final part of this memorandum is proposed future work as an extension of the initial reports.

Flexible pneumatic twisting actuators

Compliant pneumatic actuators have attracted the interests of the robotics community especially for applications where large strokes are needed in delicate environments. This paper introduces a new type of compliant actuator that generates a large twisting deformation upon pressurization. This deformation is similar to torsion in solid mechanics, and can be characterized by a twisting angle along the longitudinal axis of the actuator. To produce prototype actuators, a new fabrication process is developed that uses soft lithography. With this process, prototype actuators with a width of 7mm and a thickness of 0.65mm have been produced that exhibit a twisting rotation of 6.5 degrees per millimeter length at a pressure of 178kPa. Besides design, fabrication and characterization, this paper will go into detail on stroke optimization. © 2013 IEEE.
