Experiments with a Simulated Race Car Larry D. Pyeatt Adele E. Howe Colorado State University Fort Collins, CO 80523 email: fpyeatt,[email protected] URL: http://www.cs.colostate.edu/~fpyeatt,howeg Abstract We have implemented a reinforcement learning architecture as the reactive component of a two layer control system for a simulated race car. We have found that separating the layers has ...

this study investigated the utility of all of the above (aota) as a test option in multiple-choice items. it aimed at estimating item fit, item difficulty, item discrimination, and guess factor of such a choice. five reading passages of the key english test (ket, 2010) were adapted. the test was reconstructed in 2 parallel forms: test 1 did not include the abovementioned alternative, whereas te...

It is well recognized that assemblage structure of stream macroinvertebrates changes with alterations in catchment or local land use. Our objective was to understand how the trophic ecology of benthic macroinvertebrate assemblages responds to land use changes in tropical streams. We used the isotope methodology to assess how energy flow and trophic relations among macroinvertebrates were affect...

This paper shows that all shared atomic object types that can solve consensus among k > 1 processes have the same weakest failure detector in a message passing system with process crash failures. In such a system, object types such as test-and-set, fetch-and-add, and queue, known to have weak synchronization power in a shared memory system are thus, in a precise sense, equivalent to universal t...
