Coefficient inequality for qstarlike functions
(Elsevier Science Inc, 360 Park Ave South, New York, Ny 100101710 USA, 20160305)Let A be the class of analytic functions f which are regular and satisfying the conditions f (0) = 0, f'(0) = 1. In other words each f in A has the power series representation f(z) = z + a(2)z(2) + a(3)z(3) + ... in the ... 
A combinatorial discussion on finite dimensional Leavitt path algebras
(Hacettepe Univ, Fac Sci, Hacettepe Univ, Fac Sci, Beytepe, Ankara 06800, Turkey, 2014)Any finite dimensional semisimple algebra A over a field K is isomorphic to a direct sum of finite dimensional full matrix rings over suitable division rings. We shall consider the direct sum of finite dimensional full ...

Model order reduction for nonlinear Schrodinger equation
(Elsevier Science Inc, 360 Park Ave South, New York, Ny 100101710 USA, 20150501)We apply the proper orthogonal decomposition (POD) to the nonlinear Schrodinger (NLS) equation to derive a reduced order model. The NLS equation is discretized in space by finite differences and is solved in time by structure ...

On the class of harmonic mappings which is related to the class of bounded boundary rotation
(Elsevier Science Inc, 360 Park Ave South, New York, Ny 100101710 Usa, 20150915)The class of bounded radius of rotation is generalization of the convex functions. The concept of functions bounded boundary rotation originated from Loewner (1917). But he did not use the present terminology. It was Paatero ... 
Growth and distortion theorems for multivalent Janowski closetoconvex harmonic functions with shear construction method

Instructional technology as a tool in creating constructivist classrooms
(Elsevier Science Bv, Sara Burgerhartstraat 25, Po Box 211, 1000 Ae Amsterdam, Netherlands, 2013)Unlike traditional approach, constructivists view the learner as the active participant of the learning process. Constructivist instructors' main concern is providing the learners with learning environments in which they ...
