We present the CCD photometry, light curve and time series analysis of the classical nova V2275 Cyg. The source is observed for 14 nights in total using standard R filters in 2002 and 2003 with the 1.5m Russian-Turkish joint telescope (RTT150) at the TUBITAK National Observatory (TUG) in Antalya Turkey. We report the detection of two periodicities in the light curve of the nova : a) P-1=0.31449(15) d, b) P-2=0.017079(17) d. We propose that the first period is the orbital period of the system as a result of the aspect changes of the secondary irradiated by the hot WD. The second period could be a QPO originating from the oscillation of the ionization front below the inner Lagrange point as predicted by King (1989) or could be a QPO/beat period related to the magnetic nature of the WD.

Precision Measurement of the (e(+) + e(-)) Flux in Primary Cosmic Rays from 0.5 GeV to 1 TeV with the Alpha Magnetic Spectrometer on the International Space Station Aguilar, M.; et. al. (American Physical Society (APS), 2014-11-26) We present a measurement of the cosmic ray (e(+) + e(-)) flux in the range 0.5 GeV to 1 TeV based on the analysis of 10.6 million (e(+) + e(-)) events collected by AMS. The statistics and the resolution of AMS provide a precision measurement of the flux. The flux is smooth and reveals new and distinct information. Above 30.2 GeV, the flux can be described by a single power law with a spectral index gamma = -3.170 +/- 0.008(stat + syst) +/- 0.008(energy scale).
Time-domain mapping of electromagnetic ray movement inside anisotropic spherical resonator Biber, A; Golick, A; Tomak, Mehmet (2002-09-01) This paper presents the analytical proof of "Time-Domain Mapping Method" for the spherical resonator made up of uniaxial crystal. In this way, the main types of caustics inside the spherical resonator made up of uniaxial crystal, which were investigated numerically before, are confirmed analytically. It is engraved that the problem of the ray flow inside the spherical resonator can be reduced to the problem of the ray flow inside metal cavity shaped as spheroid.
WEIGHTED HOMOGENEOUS SINGULARITIES AND RATIONAL HOMOLOGY DISK SMOOTHINGS Bhupal, Mohan Lal (2011-10-01) We classify the resolution graphs of weighted homogeneous surface singularities which admit rational homology disk smoothings. The nonexistence of rational homology disk smoothings is shown by symplectic geometric methods, while the existence is verified via smoothings of negative weight.
Magnetic dipole moment of the light tensor mesons in light cone QCD sum rules Alıyev, Tahmasıb; Savcı, Mustafa (IOP Publishing, 2010-07-01) The magnetic dipole moments of the light tensor mesons f(2), a(2) and the strange K-2*(0)(1430) tensor meson are calculated in the framework of the light cone QCD sum rules. It is observed that the values of the magnetic dipole moment for the charged tensor particles are considerably different from zero. These values are very close to zero for the light neutral f(2) and a(2) tensor mesons, while it has a small nonzero value for the neutral strange K-2*(0)(1430) tensor meson.
Optimum topological design of geometrically nonlinear single layer lamella domes using harmony search method Çarbaş, Serdar; Saka, Mehmet Polat; Department of Engineering Sciences (2008) Harmony search method based optimum topology design algorithm is presented for single layer lamella domes. The harmony search method is a numerical optimization technique developed recently that imitates the musical performance process which takes place when a musician searches for a better state of harmony. Jazz improvisation seeks to find musically pleasing harmony similar to the optimum design process which seeks to find the optimum solution. The optimum design algorithm developed imposes the behavioral ...
