With application of electrical power, current flows in the resistive element, generating heat. The resistive element temperature rises and heat is conducted across the insulation. At high power-density, the low thermal conductance of the insulation causes the resistive element to reach unacceptably high temperatures, and this limits performance. Consequently, power densities are generally limited to less than 50W/cm2 surface area. The High Power-Density Plane-Surface H...Tue, 24 Jul 2012 09:30:40 GMTalexv@unr.eduhttp://unr.testtechnologypublisher.com/technology/5849Hybrid human/robot coordinated joint motion control architecture for application in unstructured environments involving iterative or repetitive taskshttp://unr.testtechnologypublisher.com/technology/5825Robotics used in the manufacturing industry cannot be aptly applied in machinery operations that require complex operations and variable tasks or a changing environment that is unstructured and requires on-going adjustment.
