Matched Filtering is an important part of the radar and sonar systems. Implementation of match filtering in time or frequency domain can be more advantageous due to bandwidth constraints. Another important part in match filtering is unwanted sidelobes. These sidelobes can be detected as a main part of another signal and it can be misleading. In literature, lots of methods have been proposed to reduce sidelobes. Each method has advantages and disadvantages regarding resource usage and speed. In this work, ma...
Abundance of Real Lines on Real Projective Hypersurfaces
Finashin, Sergey (2013-01-01)
We show that a generic real projective n-dimensional hypersurface of degree 2n-1 contains many real lines, namely not less than (2n-1)!!, which is approximately the square root of the number of complex lines. This estimate is based on the interpretation of a suitable signed count of the lines as the Euler number of an appropriate bundle.
Spectrofluorimetric determination of organic and inorganic selenium in vitamin supplements after cloud point extraction
Maden, Mervegül; Volkan, Mürvet; Department of Chemistry (2010)
Selenium is a trace and essential element for good health but required only in very narrow range. Hence, determination of selenium in trace level in any matrix related with human health is important. A preconcentration method is performed to obtain a low detection limit for analyte. In this study, the methodology of cloud point extraction (CPE) was used as the preconcentration method for speciation of selenium in vitamin tablets. Non-ionic surfactant Triton X-114 and a fluorimetric ligand, 2,3- diaminonapht...
Viscoelastic properties of reactive and non-reactive styrene-maleic anhydride olefinic blends
Bayram, G; Yılmazer, Ülkü; Xanthos, M (2000-05-11)
Reactive blends of styrene-maleic anhydride (SMAH) with polyethylene/methyl acrylate/glycidyl methacrylate (PE-F) and non-reactive blends of SMAH with polyethylene/methyl acrylate (PE-NF) were produced and characterized in terms of morphology and viscoelastic properties in order to understand the reaction characteristics between anhydride/epoxy functional groups. Storage modulus, G', loss modulus, G " and complex viscosity, eta* of reactive blends at 25 % and 50 % PE-F were higher than those of non-reactive...
Thermal analysis of a new thiophene derivative and its copolymer
Aslan, E.; Toppare, Levent Kamil; Hacaloğlu, Jale (2008-06-01)
Thermal characteristics of a new thiophene derivative, 2-(thiophen-3-yl-)ethyl octanoate (OTE), its homopolymer (POTE), and copolymer with thiophene P(OTE-co-Th) were investigated via pyrolysis mass spectrometry. Thermal degradation of the copolymer started by lose of side chains and thiophene involving products evolved almost in the same temperature range where PTh degradation was detected, at slightly higher temperatures than PTh backbone decomposed during the pyrolysis of POTE. The extent of doping and n...
