SHIP Search for Hidden Particles at CERN



Orbay Akcengiz, Ezgi; Sezer Uzol, Nilay (2019-10-30)
In this study, Computational Fluid Dynamics simulations of ship airwake for a simple ship geometry are performed for the horizontal and inclined deck configurations and also with and without the helicopter rotor hovering over the deck. In order to investigate the effect of the inclined flight deck due to ship motion, 10 degree roll about longitudinal-axis is given to SFS2. Full-scale, four-bladed S-76 helicopter rotor is selected as the rotor model. Rotor only case in hover is first solved and validated wit...
Ship detection in synthetic aperture radar (SAR) images by deep learning
Ayhan, Oner; Sen, Nigar (2019-01-01)
In this paper, we propose a Convolutional Neural Network (CNN) based method to detect ships in Synthetic Aperture Radar (SAR) images. The architecture of proposed CNN has customized parts to detect small targets. In order to train, validate and test the CNN, TerraSAR-X Spot mode images are used. In the phase of data preparation, a GIS (Geographic Information System) specialist labels ships manually in all images. Later, image patches that contain ships are cropped and ground truths are also obtained from pr...
Vessel Classification on UAVs using Inertial Data and IR Imagery
Demir, H. Seckin; Akagündüz, Erdem; Pakin, S. Kubilay (2015-01-01)
In this study, a civilian ship dataset is constructed via images captured by an infrared camera on an unmanned flying vehicle. By using this dataset and synchronized inertial data (UAV altitude and orientation, gimbal angles), a vessel classification method is proposed. The method first calculates the ship base length in meters by using segmented ship image and inertial data. By fusing the descriptors obtained from the segmented ship images and estimated ship base length, vessel classification is performed.
Helicopter Slung Load Simulations Using Heli-Dyn+
Yavrucuk, İlkay (null; 2013-08-13)
This paper demonstrates a fast and convinent way to model the dynamics of a helicopter with a slung load. A new software tool called Heli-Dyn+ is used to generate high fidelity helicopter math models. One of the benefits of Heli-Dyn+ is that helicopter math models can be exported as dynamic libraries into different software environments. In this paper we develop a generic 3-DOF slung load dynamic model in MATLAB/Simlulink. Then the slung load model is integrated with a nonlinear 6-DOF helicopter model expor...
Antenna Scan Period Estimation of Radars with Cepstrum and Scoring
Kalfaoglu, M. Esat; Can, Ogul; Yildirim, Berkin; Alatan, Abdullah Aydın (2019-01-01)
The performance of the cepstrum method on the radar antenna scan period estimation is evaluated. In addition, instead of relying on the cepstrum estimation directly, a two-block algorithm is proposed by adding a scoring block to make the estimation more reliable. Cepstrum is compared with zero-padded Fast Fourier Transform (FFT), zero-padded periodogram and Pulse Repetition Interval (PRI) transform. Cepstrum has been observed to be superior in six of the seven groups in the radar data set with respect to pe...
