The doping profile optimization in semiconductor has been tackled as a constrained optimization problem coupled with a drift-diffusion model to simulate the physical phenomenon. A new population-based algorithm, the Constrained Immunological Algorithm, has been introduced and the experimental results confirm that clearly outperforms previous state-of-theart algorithms in doping profile optimiza...

The shape of wake behind a wind turbine is normally assumed to have a hat shape for the models used in wind farm layout optimization purposes; however, it is know from experimental tests and numerical simulations that this is not a real assumption. In reality, the results of actual measurements and detailed numerical simulation show that the velocity in wake region has a S-shape profile. Th...

In this paper, we focus on a typical cooperative communication system with one pair of source and destination, where a unmanned aerial vehicle (UAV) flying from a start location to an end location serves as a mobile relay. To efficiently utilize energy in ambient environment, the UAV’s transmission capability is powered exclusively by radio signal transmitted from the source via the power-split...

This paper describes and evaluates the profile-based optimizations in the Compaq C compiler tool chain for Alpha. The optimizations include superblock formation, inlining, commando loop optimization, register allocation, code layout, and switch statement optimization. The optimizations either are extensions of classical optimizations or are restructuring transformations that enable classical op...

In order to improve accuracy and convergence speed for flight trajectory optimization program in flight management computer and enhance its maintainability, an improved particle swarm optimization (PSO) algorithm with object-oriented performance database is proposed. Firstly, an object-oriented performance database is built by Microsoft Visual C++ and MATLAB/SIMULINK mixed software development ...
