This paper deals with the threshold radius that warrants the use of single restraining rail for transit and railroads. Different railways use different threshold radius from 91m to 365m to provide restraining rail. These threshold figures are probably experience driven choices. The need for restraining rail may be related to a so-called derailment alarm coefficient of 1.2 sustained over 2m leng...

Aerosonde is a small autonomous aircraft (UAV) designed for meteorological sampling along a specified flight plan. This aircraft is currently being used by the Flight Systems Laboratory at the University of Washington as a test-bed for the development of a rapid control-law prototyping platform based on Matlab/Simulink/Real-Time Workshop environment. To accurately track a set of pre-planned fli...
