Variable Fidelity Optimization Using a Kriging Based Scaling Function
Solving design problems that rely on very complex and computationally expensive calculations using standard optimization methods may not be feasible given design cycle time constraints. Variable fidelity methods address this issue by using lower fidelity models and a scaling function to approximate the higher fidelity models in a provably convergent framework. In the past, scaling functions hav...
متن کاملMeasurement and Computational Modeling of Radio-Frequency Electromagnetic Power Density Around GSM Base Transceiver Station Antennas
Evaluating the power densities emitted by GSM1800 and GSM900 BTS antennas isconducted via two methods. Measurements are carried out in half a square meter grids around twoantennas. CST Microwave STUDIO software is employed to estimate the power densities in order fordetailed antenna and tower modeling and simulation of power density. Finally, measurements obtainedfrom computational and experime...
متن کاملModeling Light Sources for Accurate Simulations
abstract Producing realistic computer generated images has been a focus of computer graphics in recent years, and some papers have proposed methods for handling the geometric or spectral information of light sources. However, lighting engineering applications need to solve many problems in order to substitute accurate visual computer simulations for full scale tests. Solutions are proposed in t...
متن کاملMicrowave Antennas and Circuits Modeling Using Electromagnetic Field Simulator
Electromagnetic field simulators have become a widely used tool in a design process of microwave circuits and systems. A proper usage of electromagnetic (EM) field simulators allows substantial reduction of the design time providing reliable results. In such case the required parameters of the designed circuit can be reached even at the first manufactured prototype in spite of high complexity o...
