Slip suppression in prosthetic hands using a reflective optical sensor and MPI controller
Nakagawa-Silva, Andrei; Sunkesula, Sai Praneeth Reddy; Prach, Anna; Cabibihan, John-John; Thakor, Nitish V.; Soares, Alcimar B. (2018-10-19)
Prosthetic hands have greatly evolved in mechatronic, robotic and control aspects. However, occasional accidents might happen due to excessive grip force or the breaking of contact due to slip. Fast transient slip events c...
Efficient structural optimization for multiple load cases using adjoint sensitivities
Akgun, MA; Haftka, RT; Wu, KC; Walsh, JL; Garcelon, JH (American Institute of Aeronautics and Astronautics (AIAA), 2001-03-01)
Adjoint sensitivity calculation of stress, buckling, and displacement constraints may be much less expensive than direct sensitivity calculation when the number of load cases is large. In general, it is more difficult to i...
Multi-spectral False Color Shadow Detection
Teke, Mustafa; Baseski, Emre; Ok, Ali Ozgun; Yuksel, Baris; Senaras, Caglar (2011-10-07)
With the availability of high-resolution commercial satellite images, automated analysis and object extraction became even a more important topic in remote sensing. As shadows cover a significant portion of an image, they ...
Measurements of dynamic stability derivatives using direct forced oscillation technique
Alemdaroglu, N; Iyigun, I; Altun, M; Quagliotti, F; Guglieri, G (2001-08-30)
The subject of the experimental investigation presented in this paper is to measure the dynamic stability derivatives of a generic combat aircraft model in the Ankara Wind Tunnel by using the direct forced oscillation tech...
Cell-vertex based parallel and adaptive explicit 3D flow solution on unstructured grids
Yilmaz, E; Kavsaoglu, MS; Akay, HU; Akmandor, IS (Informa UK Limited, 2001-01-01)
A parallel adaptive Euler flow solution algorithm is developed for 3D applications on distributed memory computers. Significant contribution of this research is the development and implementation of a parallel grid adaptat...
System identification with generalized orthonormal basis functions: an application to flexible structures
Nalbantoglu, V; Bokor, J; Balas, G; Gaspar, P (Elsevier BV, 2003-03-01)
This paper presents an application of a multi-input/multi-output identification technique based on system-generated orthonormal basis functions to a flexible structure. A priori information about the poles of the system, p...
"ROTATION OF MATERIAL AXES EFFECTS ON FREE BENDING VIBRATIONS RESPONSE OF COMPOSITE MINDLIN BASE PLATES OR PANELS STIFFENED BY THREE BONDED PLATE STRIPS"
Yuceoglu, U.; Javanshir, J.; Farsadi, T.; Guvendik, O. (2011-11-17)
In the present study, the rotation of material axes on the free bending vibrations response of a certain type of composite "Bonded and Stiffened System" is theoretically analyzed and numerically solved with some numerical ...
ANALYSIS of FREE FLEXURAL VIBRATIONS of COMPOSITE MINDLIN BASE PLATES or PANELS REINFORCED by THREE BONDED PLATE STRIPS
Yuceoglu, Umur; Javanshir, Jaber; Amireghbali, Aydin; Guvendik, Ozen (2010-11-18)
The present study is about the theoretical analysis and the numerical solutions of the free vibrations of a certain type of the "Bonded and Stiffened System". In other words, the "Free Bending Vibrations of Composite Mindl...
Effects of Noises in Images used for Height Map Reconstruction of Cartridge Cases using Photometric Stereo
Ozturk, A. Oguz; Birgul, Ozlem; Esen, Ersin; Sakarya, Ufuk (2009-04-11)
Photometric stereo (PS) is commonly used in examination of ballistic marks and this stud), investigated the effects of noises present in images on the reconstructed depth map based on PS and the sensitivity of different er...
