Concurrent multiband receivers receive and process multiple frequency bands simultaneously. They are thus capable of providing multitask or multifunction to meet consumer needs in modern wireless communications. Concurrent multiband receivers require at least some of their components to operate concurrently at different frequency bands which results in substantial reduction of cost and power dissipation. Fi Read More

Given a water-terrain area of interest (waterways, ports, etc.), this paper attempts to efficiently allocate underwater sonars to achieve a reasonable amount of coverage within a limited budget. Coverage is defined as the capability of sonars to detect threats. Though total coverage is desired, priority is given to the criticality/importance attached to the location of an area of interest on a grid-based system. Unlike other works in Read More

The traditional cycle in the simulation of the electron avalanches and any scientific simulation is to prepare input, execute a simulation, and to visualize the results as a post-processing step. Usually, such simulations are long running and computationally intensive. It is not unusual for a simulation to keep running for several days or even weeks. If the experiment leads to the conclusion that there is incorrect logic in the a Read More

The automated and simultaneous extraction of multiple phase distributions and their derivatives continue to pose major challenges. A possible reason is the lack of proper data processing concepts to support the multiple wave mixing that needs to be introduced to make the configuration at a time sensitive to multiple phase components and yet be able to decrypt each component of the phase efficiently and robustly, in abse Read More

Fault diagnosis (FD) has received much attention for complex modern automatic systems such as car, aircraft, rockets, unmanned vehicles, and so on since 1970s.
