Our results are also used to address the general problem of synchronization of multiple Lagrangian systems. The problems of multi-robot coordination and of bilateral teleoperation with time delay are shown to be special ...

The National Aeronautics and Space Administration (NASA), in addition to an increasing number of privately funded ventures, has demonstrated growing interest in more electric aircraft (MEA) - flight vehicles where propulsion ...

Landscape evolution models (LEMs) have been used as tools for geomorphologist to explain and understand mountain formation and landform development. Initially these models were conceptual ideas of how geomorphic processes ...

Conventional A/D conversion circuits require high-performance analog circuits requiring exquisite design. A novel way to convert analog signal is presented here using a mostly-digital frequency discriminator with low cost. ...

This report presents an overview of selected seismic hazard analysis (SHA) methodologies. First, background information about earthquakes is presented, followed by more rigorous treatment of acceleration attenuation ...

Controversy regarding the mechanism(s) responsible for the retention of alumina scales formed on NiAlCr alloys containing reactive elements remains. Laser cladding is the process where a mechanical mixture of powders is ...

The oxidation states of Cu on the (001) MgO surface have been studied with an Ab-Initio cluster (S-atoms-plus-charge-array) calculation in the Hartree-Fock approximation, for two cases: (i) Cu above a surface oxygen, and ...
