in this paper, a new design of optical channel drop filter based on two- dimensional photonic crystal ring resonators with triangular lattice is proposed. the rods of this structure is silicon with the refractive index nsi=3.46 and the surrounding environment is air with the refractive index of nair=1.the widest photonic band gap obtains for the filling ratio of r/a = 0.2. the filter’s transmis...
we define a new type of spectrum, called δ-approximate spectrum, of an element a in a complex unital banach algebra a and show that the δ-approximate spectrum σ_δ (a) of a is compact. the relation between the δ-approximate spectrum and the usual spectrum is investigated. also an analogue of the classical gleason-kahane-zelazko theorem is established: for each ε>0, there is δ>0 such that if ϕ is...
Introduction: Autism is one of the most common neurodevelopmental disorders that is diagnosed late due to parentschr('39') unfamiliarity with the disorder. Lack of knowledge of parents is one of the major problems of this disorder. The objective of this study was to develop an educational smartphone-based application for autism spectrum disorder specific for parents. Method: This study was an a...
Background: The presence of children with autism spectrum disorder in the family imposes great pressure on family members especially on mothers. Mothers of children with autism spectrum disorder are faced with numerous challenges that expose them to high levels of stress and other negative psychological consequences. This study is conducted in order to compare levels of perceived stress, family...

The Impact of Emotion Regulation Training on Social Skills of Children with Autism Spectrum Disorder
Background and Purpose: Since children with autism spectrum disorder are at risk for emotional and social problems, the purpose of this study was to investigate the effectiveness of emotional regulation training on social skills of children with autism spectrum disorder. Methods: The research method was quasi-experimental with pretest-posttest and control group design. For this purpose, 25 chil...
This study set out to determine the impact of a family-centered problem-solving program on emotional regulation of mothers of students with autism spectrum disorder. The research had a pretest-posttest control group design with a follow-up session. The statistical population of the study was comprised of all mothers of students with autism spectrum disorder in Kermanshah in 2018-19 school year....
Earthquake time history records are required to perform dynamic nonlinear analyses. In order to provide a suitable set of such records, they are scaled to match a target spectrum as introduced in the well-known design codes. Corresponding scaling factors are taken similar in practice however, optimizing them reduces extra-ordinary economic charge for the seismic design. In the present work a ne...
