Finite difference method for a nonlinear fractional Schrödinger equation with Neumann condition

In this paper, a special case of nonlinear fractional Schrödinger equation with Neumann boundary condition is considered. Finite difference method is implemented to solve the nonlinear fractional Schrödinger problem with Neumann boundary condition. Previous theoretical results for the abstract form of the nonlinear fractional Schrödinger equation are revisited to derive new applications of these theorems on the nonlinear fractional Schrödinger problems with Neumann boundary condition. Consequently, first and second order of accuracy difference schemes are constructed for the nonlinear fractional Schrödinger problem with Neumann boundary condition. Stability analysis show that the constructed difference schemes are stable. Stability theorems for the stability of the nonlinear fractional Schrödinger problem with Neumann boundary condition are presented. Additionally, applications of the new theoretical results are presented on a one dimensional nonlinear fractional Schrödinger problem and a multidimensional nonlinear fractional Schrödinger problem with Neumann boundary conditions. Numerical results are presented on one and multidimensional nonlinear fractional Schrödinger problems with Neumann boundary conditions and different orders of derivatives in fractional derivative term. Numerical results support the validity and applicability of the theoretical results. Numerical results present the convergence rates are appropriate with the theoretical findings and construction of the difference schemes for the nonlinear fractional Schrödinger problem with Neumann boundary condition

Discrete Element Method Modelling of the Particle Flow in Centrifugal Solar Particle Receiver

The centrifugal solar particle receiver (CentRec) is a promising design compared to other particle receiver concepts because it allows for an active adjustment of particle residence time and particle outlet temperature by adjusting the rotational speed of the drum and particle mass flow rate. A Discrete Element Method (DEM) tool is utilized to model the particle flow in CentRec. However, the numerical modeling of the particle flow in large scale receiver is computationally infeasible because of excessive number of particles in the simulation. Thus, in this study, a scale down approach is developed and validated to be used to estimate the particle film characteristics in large scale receivers. The particle velocity profile and film thickness distribution are employed to compare different receiver sizes

Self-Handicapping and Its Impact on Mental Health

Self handicapping is characterized by experiencing anxiety at succeeding a mission although the person has the capacity to fulfill the assignment or duty. It describes one's showing tendency to link own failures to problems in own performance instead of own abilities to protect oneself from the possibility of failure. When individuals care about performance much but doubt about success, they display self-handicapping strategies to protect their self. Self-handicappers try to protect their self by internalizing successes and externalizing failures. This strategies help them feel well in both successes and failures. Self-handicapping becomes a trait of personality in time and the individual begins to use it continuously as a negative coping mechanism to protect his/her self and to avoid failures. These actions eliminates the capability of rational thinking and prevents solution of the problems as a result of irrational interpretations. Self-handicapping causes the decrease of life satisfaction and motivation, and causes the increase of maladaptation, negative mood, somatic symptoms and alcohol-drug abuse. As a conclusion, self-handicapping hinders performance and this negative performance influences adaptation and psychological well-being. The most essential approach to prevent occurrence of self-handicapping behaviours is empowerment of the self. [Psikiyatride Guncel Yaklasimlar - Current Approaches in Psychiatry 2016; 8(2): 145-154
