Multinucleon transfer mechanism in the collision of U-238 + U-238 system is investigated at E-c.m. = 833 MeV in the framework of the quantal diffusion description based on the stochastic mean-field approach. Double cross sections sigma (N, Z) as a function of the neutron and proton numbers, the cross sections sigma(Z) and sigma(A) as a function of the atomic numbers and the mass numbers are calculated for production of the primary fragments. The calculation indicates the U-238 + U-238 system may be located at an unstable equilibrium state at the potential energy surface with a slightly negative curvature along the beta stability line on the (N, Z) plane. This behavior may lead to rather large diffusion along the beta stability direction.

Employing the quantal diffusion mechanism for multinucleon transfer, the double differential cross sections are calculated for production of primary projectile-like and target-like fragments in collisions of Xe-136 + Pb-208 system at E-c.m. = 514 MeV. Including de-excitation due to neutron emission, the cross section for production of Po-210, Rn-222, and Ra-224 isotopes are estimated and compared with data.
Assessment of an iterative approach for solution of frequency domain linearized euler equations for noise propagation through turbofan jet flows
Dizemen, İlke Evrim; Yörükoğlu, Yusuf; Department of Aerospace Engineering (2007)
This study, explores the use of an iterative solution approach for the linearized Euler equations formulated in the frequency domain for fan tone noise propagation and radiation through bypass jets. The aim is to be able to simulate high frequency propagation and radiation phenomena with this code, without excessive computational resources. All computations are performed in parallel using MPI library routines on a computer cluster. The linearized Euler equations support the Kelvin-Helmholtz type convective ...
Combining perturbation theory and transformation electromagnetics for finite element solution of Helmholtz-type scattering problems
Kuzuoğlu, Mustafa (2014-10-01)
A numerical method is proposed for efficient solution of scattering from objects with weakly perturbed surfaces by combining the perturbation theory, transformation electro-magnetics and the finite element method. A transformation medium layer is designed over the smooth surface, and the material parameters of the medium are determined by means of a coordinate transformation that maps the smooth surface to the perturbed surface. The perturbed fields within the domain are computed by employing the material p...
Failure analysis of shear critical RC structural members
Sarıtaş, Afşin (2004-06-01)
This paper presents a beam finite element for the simulation of the monotonic and cyclic response of RC structural members under the interaction of flexure, axial force and shear. The proposed beam element follows the assumptions of the Timoshenko shear beam theory with a three-field Hu-Washizu variational formulation for the derivation of the element response. The nonlinear response of the element is obtained through section integration of nonlinear material response. A 3d plastic damage model for cyclic a...

Ayik, S.; YILMAZ TÜZÜN, ÖZGÜL; YILMAZ, BÜLENT; Umar, A. S.; GÖKALP, AHMET; Turan, Gürsevil; Lacroix, D. (2015-05-04)
The nucleon exchange mechanism is investigated in central collisions of symmetric heavy ions in the basis of the stochastic mean-field approach. Quantal diffusion coefficients for nucleon exchange are calculated by including non-Markovian effects and shell structure. Variances of fragment mass distributions are calculated in central collisions of Ca-40 + Ca-40, Ca-48 + Ca-48, and N-56 i+ Ni-56 systems.
