We report the results of analysis of observations of the Vela Pulsar by PCA on RXTE. Our data consists of two parts. The first part contains observations at 1, 4, and 9 days after the glitch in 1996 and has 27000 sec, total exposure time. The second part of observations were performed three months after this glitch and have a total exposure time of 93000 sec. We found pulsations in both sets. The observed spectrum is a power-law with no apparent change in flux or count rate. The theoretical expectations of increase in flux due to internal heating after a glitch are smaller than the uncertainty of the observations.

EXPECTANCY OF LARGE PULSAR GLITCHES - A COMPARISON OF MODELS WITH THE OBSERVED GLITCH SAMPLE ALPAR, MA; Baykal, Altan (1994-08-15) We study the expectancy of large glitches (DELTAOMEGA/OMEGA > 10(-7)) from a sample of 430 pulsars other than the Vela pulsar. The pulsars in this sample have exhibited 19 large glitches. We assume that all pulsars experience such glitches, with rates that depend on the pulsar's rotation rate OMEGA and spin-down rate OMEGA, and on the glitch model. We use the core-quake model, and two variants of the superfluid vortex unpinning model, and choose model parameters such that the observed number of glitches is ...
Application of artificial neural network and logistic regression methods to landslide susceptibility mapping and comparison of the results for the ulus district, Bartin Bartin, ulus ilçesi için yapay sinir aǧi ve lojistik regresyon yöntemlerinin heyelan duyarlilik çalişmasina uygulanmasi ve karşilaştirilmasi Eker, Arif Mert; Dikmen, Mehmet; Cambazoǧlu, Selim; Düzgün, Şebnem H.s.b.; Akgün, Haluk (2012-03-01) Bu çalışma, Coğrafi Bilgi Sistemlerine (CBS) dayalı lojistik regresyon (LR) ve yapay sinir ağı (YSA) analizlerini kullanarak, Karadeniz bölgesindeki Bartın ilinin Ulus ilçesi için bir heyelan duyarlılık haritası hazırlamayı amaçlamaktadır. Bu araştırma kapsamında, Maden Tetkik ve Araştırma Genel Müdürlüğü tarafından hazırlanan heyelan envanter haritası, heyelan sınıflandırma haritasına temel olarak alınmıştır. Çalışma alanındaki analizlerin tamamı aktif heyelanlara istinaden gerçekleştirilmiştir. Bununla bi...
Practical tools for ranking and selection of groundmotion prediction equations (GMPEs) for probabilistic seismic hazard assessment and development of a regional GMPE Kale, Özkan; Akkar, Sinan; Danciu, Laurentiu; Department of Civil Engineering (2014) This study starts summarizing the progresses in ground-motion databases and ground-motion models in pan-European region and consequent seismic hazard comparisons conducted for individual local and global predictive models. Then, the study presents the compilation of the Middle East region and Turkish ground-motion databases with principle seismological features to be mainly used in predictive model selection process in these regions. In the following step, using a high standard subset of the Middle East gro...
Temperature-dependent radiative lifetimes of excitons in non-polar GaN/AlGaN quantum wells Rudin, S.; Garrett, G. A.; Shen, H.; Wraback, M.; İmer, Muhsine Bilge; Haskell, B.; Speck, J. S.; Keller, S.; Nakamura, S.; DenBaars, S. P. (2007-01-01) We report theoretical and experimental studies of radiative recombination of carriers in GaN quantum wells grown on low defect a-plane GaN templates fabricated by lateral epitaxial overgrowth. The radiative rates are presented as functions of temperature and well width.
Experimental Characterization of Micro Vortex Generators in Low Speed Flows Akpolat, Tuğrul; Abdulrahim, Anas; Hassanein, Abdelrahman; Uzol, Oğuz; Perçin, Mustafa (2021-09-08) In this study, we present the experimental results of the characterization of micro-ramp type Micro Vortex Generators (MVGs) in low-speed flows. The undisturbed boundary layer profile was measured by means of Hot-Wire Anemometry. Two MVGs with the same design but different height-to-boundary layer thickness ratios are used in this study. Two-dimensional twocomponent particle image velocimetry measurements are conducted in the wake of the MVGs. The results reveal the lift-off of the wake away from the wall f...
