(Nelvin C. Cepeda / The San Diego Union-Tribune) Two of the field’s approach lighting systems for the runway, which help to direct a pilot on the correct glide slope and to line up with the ...

The exact slope of the isoquant curve on the graph shows the rate at which a given input, either labor or capital, can be substituted for the other while keeping the same output level. In the ...

Abstract: A hybrid global-local optimization technique for the design of antennas is presented. It consists of the subsequent application of a genetic algorithm (GA) that employs coarse models in the ...

Abstract: This paper presents an investigation of dispersive behavior of glide-symmetric parallel-plate waveguides ... the design of EBGs while the latter to the design of leaky-wave antennas with ...
