Greedy Gaussian Process Regression Applied to Object Categorization and Regression
(Association for Computing Machinery, 18 Decembe)In this work we propose an approximation of Gaussian Process and apply it to Classification and Regression tasks. We, primarily, target the problem of visual object categorization using a Greedy variant of Gaussian Processes. ... -
Reconnaissance attack detection via boosting machine learning classifiers
(American Institute of Physics Inc., 20 October)With the advancement of Internet technologies, network security concerns are growing exponentially. One of the most difficult issues of network security is keeping it safe. To detect and identify any malicious behavior the ... -
Photoionization of endohedral atoms using R-matrix methods: Application to Xe@C-60
(AMER PHYSICAL SOC, 2012-09-21)It is demonstrated that the effect of a static cage potential on the photoionization of endohedrally enclosed atoms can be incorporated into standard R-matrix calculations using one of two independent methods. For ... -
Photoionization of confined Ca in a spherical potential well
(AMER PHYSICAL SOC, 2013-01-09)The photoionization cross section of the Ca atom, confined by a spherical annular potential, has been calculated using a modification to the Belfast R-matrix code for a variety of depths of the confining potential. The ... -
Probing confinement resonances by photoionizing Xe inside a C-60(+) molecular cage
(AMER PHYSICAL SOC, 2013-11-01)Double photoionization accompanied by loss of n C atoms (n = 0, 2, 4, 6) was investigated by merging beams of Xe@C-60(+) ions and synchrotron radiation and measuring the yields of product ions. The giant 4d dipole resonance ... -
A comprehensıve x-ray absorptıon model for atomıc oxygen
(Iop Publıshıng Ltd, 2013-12-10)An analytical formula is developed to accurately represent the photoabsorption cross section of O I for all energies of interest in X-ray spectral modeling. In the vicinity of the K edge, a Rydberg series expression is ... -

K-SHELL PHOTOABSORPTION OF MAGNESIUM IONS
(IOP PUBLISHING LTD, 2014-09)X-ray photoabsorption cross sections have been computed for all magnesium ions with three or more electrons using the R-matrix method. A comparison with other available data for Mg II-Mg x shows good qualitative agreement ... -
Particle-filter-based pose Estimation from Controlled Motion with Application to Visual Servoing
(SAGE PUBLICATIONS INC, 2014-10-31)In this paper, we present a Bayesian algorithm based on particle filters to estimate the camera pose for vision-based control. The state model is represented as a relative camera pose between the current and initial camera ... -
Path planning for visual servoing and navigation using convex optimization
(ACTA PRESS, 2015)Exploiting visual cues to control systems for robotic applications is a promising idea. Practically, they are usable only if the end result accedes to the restrictions of the specific environment. These restrictions are ... -
