Compatibilization and characterization of blends of styrene-maleic anhydride copolymer with modified polyethylenes
Bayram, G; Yılmazer, Ülkü; Xanthos, M (Wiley, 2001-05-02)
Potentially reactive blends of styrene-maleic anhydride (SMAH) with ethylene/methyl acrylate/glycidyl methacrylate (E-MA-GMA) and nonreactive blends of SMAH with ethylene/methyl acrylate (E-MA) were produced in a Brabender batch mixer and in a corotating twin-screw extruder. The products were characterized in terms of rheology, morphology, and mechanical properties to understand the reaction characteristics between anhydride/epoxy functional groups. Storage modulus, G', loss modulus, G" and complex viscosit...
Compatibilization of poly(2,6-dimethyl-1,4-phenylene oxide) and poly(2,6-dichloro-1,4-phenylene oxide) with sulfonated polystyrene and its Na and Zn-neutralized ionomers
Mih, M; Aras, L; Alkan, C (Springer Science and Business Media LLC, 2003-05-01)
Compatibility of acidic (H), Na, and Zn neutralized sulfonated polystyrene ionomer blends with Poly(2,6-dimethyl-1,4-phenylene oxide) (PPO) and Poly(2,6-dichloro-1,4-phenylene oxide) (PDCIPO) was investigated by Dilute Solution Viscometry (DSV) and Differential Scanning Calorimetry (DSC). The intrinsic viscosities of the blends, are measured in suitable solvents. The degree of compatibility of the blends is characterized by Ab parameter. According to the results, PPO is completely miscible, except for Na-ne...
Compressive sensing methods for multi-contrast magnetic resonance imaging
Güngör, Alper; Yarman Vural, Fatoş Tunay; Çukur, Tolga; Department of Computer Engineering (2017)
Compressive sensing (CS) is a signal processing tool that allows reconstruction of sparse signals from highly undersampled data. This study investigates application of CS to magnetic resonance imaging (MRI). In this study, first, an optimization framework for single contrast CS MRI is presented. The method relies on an augmented Lagrangian based method, specifically alternating direction method of multipliers (ADMM). The ADMM framework is used to solve a constrained optimization problem with an objective fu...
Compressive Sensing Imaging with a Graphene Modulator at THz Frequency in Transmission Mode
Özkan, Vedat Ali; Takan, Taylan; Kakenov, N.; KOCABAŞ, COŞKUN; Altan, Hakan (2016-09-30)
In this study we demonstrate compressive sensing imaging with a unique graphene based optoelectronic device which allows us to modulate the THz field through an array of columns or rows distributed throughout its face.
