Multi Block and Parallel Computations of Rotor Fan Using Three Dimensional Euler Equations

Multi-symplectic integration of coupled non-linear Schrodinger system with soliton solutions AYDIN, AYHAN; Karasözen, Bülent (2009-01-01) Systems of coupled non-linear Schrodinger equations with soliton solutions are integrated using the six-point scheme which is equivalent to the multi-symplectic Preissman scheme. The numerical dispersion relations are studied for the linearized equation. Numerical results for elastic and inelastic soliton collisions are presented. Numerical experiments confirm the excellent conservation of energy, momentum and norm in long-term computations and their relations to the qualitative behaviour of the soliton sol...
Multi-frequency contactless electrical impedance imaging using realistic head models : single coil simulations Gürsoy, Doğa; Ertan, Hulusi Bülent; Department of Electrical and Electronics Engineering (2007) Contactless electrical impedance imaging technique is based upon the measurement of secondary electromagnetic fields caused by induced currents inside the body. In this study, a circular single-coil is used as a transmitter and a receiver. The purpose of this study is twofold: (1) to solve the induced current density distribution inside the realistic head model resulting from a sinusoidal excitation, (2) to calculate the impedance change of the same coil from the induced current distribution inside the head...
Multi-source Partial Discharge Signals Discrimination by Six Bandpass filters and DBSCAN Clustering Anşin, Berfin (2018-01-01) Partial discharge (PD) signals generated by defects in a transformer insulation can be captured through measurement instruments and they may be used, after preprocessing, to discriminate the PD Sources. Some of the artificial defect models, such as: corona, internal cavity and surface discharge in air are developed in the laboratory. These defect models are put in parallel under a high voltage stress. The PD signals stemmed from these sets of multiple PD sources are captured. In this paper six bandpass filt...
Multi-Fidelity Aerodynamic Dataset Generation of a Fighter Aircraft with a Deep Neural-Genetic Network Millidere, Murat; Gomec, Fazil Selcuk; Kurt, Huseyin Burak; Akgül, Ferhat (2021-01-01) © 2021, American Institute of Aeronautics and Astronautics Inc.. All rights reserved.This paper is a follow-up study on prior research work on multi-fidelity aerodynamic dataset generation. The prior work studied a comparison of modified Variable-Complexity Modelling and co-Kriging methods applied to F-16 fighter aircraft. In this research, the multi-fidelity deep neural-genetic network method is introduced. The results provide evidence that the deep neural-genetic network method in this paper can be employ...
Multi-Project Multi-Resource Leveling Using Mixed Integer Programming Altun, Murat; Sönmez, Rifat; Akçamete Güngör, Aslı (2018-11-16) In construction projects, resource leveling aims to provide efficient resource planning during project implementation by reducing possible fluctuations in resource usage. Decision makers mostly focus on the single project to optimize its resource usage by applying various objective functions of resource leveling problem. However, in real life, multiple projects may be performed in the same time period. Hence, leveling the resources of each project separately generates sub-optimal solutions since interaction...
