Combined Point-Mass and Particle Filter for Target Tracking

Orguner, Umut
Tornqvist, David
Gustafsson, Fredrik
This paper presents a combined Point Mass Filter (PMF) and Particle Filter (PF), which utilizes the support of the PMF and the high particle density in the PF close to the current estimate. The result is a filter robust to unexpected process events but still with low error covariance. This filter is especially useful for target tracking applications, where target maneuvers suddenly can change unpredictably.


Analysis of the Raman intensities near the phase transitions in ammonium halides
Yurtseven, Hasan Hamit (Elsevier BV, 2008-12-01)
This study concentrates on the temperature dependence of the Raman intensities for the lattice modes in ammonium halides (NH4Cl and NH4Br) close to phase transitions, We predict their intensities using the results of a shell model for the Raman polarizability within the framework of an Ising pseudospin-phonon coupled model.
Entropy Calculation in Particle Filters
Orguner, Umut (2009-04-11)
This paper presents a differential entropy calculation method to be used for particle mixtures in particle filters. First it is shown that the exact differential entropy of particle mixtures is minus infinity and therefore useless in practice. The disadvantage of using discrete entropy formulation instead of differential entropy is also explained. Unlike the kernel-based methods in the literature, a Bayes rule based approximation is then proposed. The performance of the algorithm is illustrated on a basic G...
Extended target tracking with a cardinalized probability hypothesis density filter
Orguner, Umut; Granström, Karl (null; 2011-07-08)
This paper presents a cardinalized probability hypothesis density (CPHD) filter for extended targets that can result in multiple measurements at each scan. The probability hypothesis density (PHD) filter for such targets has already been derived by Mahler and a Gaussian mixture implementation has been proposed recently. This work relaxes the Poisson assumptions of the extended target PHD filter in target and measurement numbers to achieve better estimation performance. A Gaussian mixture implementation is d...
Combined low-temperature photoluminescence and thermally stimulated current studies in Cu3In5S9 layered single crystals
Hasanlı, Nızamı (2016-01-01)
Photoluminescence (PL) and thermally stimulated current (TSC) spectra of Cu3In5S9 layered crystals grown by Bridgman method have been studied in the photon energy region of 1.20-1.65 eV and the temperature range of 15-70 K (PL) and in the temperature region of 10-130 K (TSC). A broad PL band centered at 1.484 eV was observed at T=15 K. Radiative transitions from shallow donor level located at 16 meV to moderately deep acceptor level located at 120 meV were suggested to be responsible for the observed PL ban...
In Situ Formed "Weakly Ligated/Labile Ligand" Iridium(0) Nanoparticles and Aggregates as Catalysts for the Complete Hydrogenation of Neat Benzene at Room Temperature and Mild Pressures
Bayram, Ercan; Zahmakiran, Mehmet; Özkar, Saim; Finke, Richard G. (American Chemical Society (ACS), 2010-07-20)
"Weakly ligated/labile ligand" nanoparticles, that is nanoparticles where only weakly coordinated ligands plus the desired catalytic reactants are present, are of fundamental interest. Described herein is a catalyst system for benzene hydrogenation to cyclohexane consisting of "weakly ligated/labile ligand" Ir(0) nanoparticles and aggregates plus dry-HCl formed formed in situ from commercially available [(1,5-COD)IrCl](2) plus 40 +/- 1 psig (similar to 2.7 atm) H(2) at 22 +/- 0.1 degrees C. Multiple control...
