Real Time Visualization and Steering of Large Scale Parallel Simulations
Tonkal, Ozan Çağrı; Pehlivan, Sercan; Sezer Uzol, Nilay; İşler, Veysi (nsezeruzol.etu.edu.tr; 2004-08-12)
While a tremendous amount of work has gone into developing Computational Fluid Dynamics(CFD) software, little has been done to develop computational steering and visualization tools thatcan be easily integrated with this software. Computational steering can be used to visualize CFD solutions while they are being computed and change simulation parameters “on the fly.” In this paper we explore the use of the general-purpose computational steering software (POSSE) coupledwith a parallel, 3-D Navier-Stokes flow...
Realtime Magnetometer Calibration for Spinning Aerospace Vehicles
Çetin, Mustafa Efe; Söken, Halil Ersin; Tekinalp, Ozan; Department of Aerospace Engineering (2022-2-8)
Magnetometers are essential sensors for attitude estimation application in small spacecrafts due to their robust, inexpensive and lightweight characteristics. However, their direct usage is not applicable due to sensor errors. These errors limit the overall attitude estimation accuracy. This study proposes a complete real-time attitude independent magnetometer calibration algorithm for spinning aerospace vehicles. The recursive algorithm aims estimating the complete error state; consisting bias, scale facto...
Real Time Path Planning for Unmanned Air Vehicles
Leblebicioğlu, Mehmet Kemal (2017-11-01)
This study is about developing an online (real-time) path planning algorithm for multiple Unmanned Aerial Vehicles (UAV). The proposed algorithm dynamically finds the path of each vehicle by solving an optimization problem over a planning horizon. The main objective of the optimization problem is to maximize the collected amount of information from targets within a certain interval of time. The importance of the information collected from a targets, if no UAV is flying on the target, decreases with time. Th...
REAL TIME CALCULATION OF SHEM ANGLES BY METAHEURISTIC ALGORITHMS FOR VARIABLE FREQUENCY MOTOR DRIVES
NALÇACI, Gamze; ERMİŞ, Muammer; ÇADIRCI, Işık; Department of Electrical and Electronics Engineering (2021-9-23)
Harris hawks optimization (HHO) has been used to optimize a voltage source inverter's selective harmonic elimination method (SHEM) for light rail transportation. The primary goal of SHEM's pulse-width modulation strategy is to eliminate low-order harmonics by solving nonlinear equations while maintaining the required magnitude of the fundamental component. When applied to a two-level, three-phase inverter, the HHO algorithm aims to solve the associated nonlinear equations with a high degree of accuracy and ...
Real time panoramic background subtraction on GPU
BÜYÜKSARAÇ, SERDAR; Akar, Gözde; Temizel, Alptekin (2016-05-19)
In this study, we propose a method for panoramic background subtraction by using Pan-Tilt cameras in real-time. The proposed method is based on parallelization of image registration, panorama generation and background subtraction operations to run on Graphics Processing Unit (GPU). Experiments results showed that GPU usage increases speed of the algorithm 33 times without considerable performance loss and makes working real-time possible.
