The importance of the equipment and secondary systems in seismic design and performance evaluation is well recognized and has been the subject of many studies. In all of these studies, earthquake is considered as a single component, and in most of them the primary system is considered as shear building. Most attention has been concentrated on the response of secondary system and its response sp...

in this research oxidation kinetic panceuo.s (p.s) by s2o8-2 at the presence of agno3 ascatalyst was studied.the method was spectrophotometer following absorption spectrum (p.s) inwave length of 518 nm. after improving the condition such as ph, p.s concentration, k2s2o8concentration, ionic strength, temperature, rate constant, activation energy, constant frequency,order reaction and thermo dyna...
با افزایش دانش بشر در باره پدیده زلزله و نحوه رفتار سازه ها در زمان زلزله، راهکارهای افزایش ایمنی در مقابل این پدیده نیز به روز می شوند. لذا هدف از این تحقیق ، ارائه دو روش تحلیل شبه استاتیکی غیرخطی به نام ، الف: روش تحلیل طیف ظرفیت capacity spectrum method و ب:روش تحلیل استاتیکی فزاینده غیرخطی مودی modal pushover analysis و مقایسه خطای آنها نسبت به روش تحلیل دینامیکی تاریخچه زمانی غیر ...
This study examined the cognitive underpinnings of spontaneous imagination in autism spectrum disorder (ASD) by way of individual differences. Children with ASD (N = 27) and matched typically developing (TD) children were administered Karmiloff-Smith's (1990) imaginative drawing task, along with measures that tapped specific executive functions (generativity, visuospatial planning, and central ...
objectives: autism spectrum disorder (asd) is a group of neurodevelopment syndromes with impairments in social communications and restrictive or repetitive behaviors. neurofeedback is a new method that may regulate neuro and metabolic function in brain. this study is semi-experimental, with pre and post test. methods: in 26 children with asd, 40 sessions of neurofeedback were done. brain waves...
We study a fundamental issue in cosmology: Whether we can rely on a cosmological model to understand the real history of the Universe. This fundamental, still unresolved issue is often called the “model-fitting problem (or averaging problem) in cosmology”. Here we analyze this issue with the help of the spectral scheme prepared in the preceding studies. Choosing two specific spatial geometries ...
Abstmet-This correspondence studies parametric estimatioll of spectral moments of a zero-mean complex Gaussian stationary pmcess immersed in independent Gaussian noise. With the merit of the maximum-likelihood @lL) approach as motivation, this work exploits a Whittle's type objective function that is able to capture the relevant feabues of the log-likelihmdfunction while b e i i much more manag...
Autism spectrum disorder (ASD) is characterised by profound difficulties in empathic processing and executive control. Whilst the links between these processes have been frequently investigated in populations with autism, few studies have examined them at the subclinical level. In addition, the contribution of alexithymia, a trait characterised by impaired interoceptive awareness and empathy, a...
This study further elaborates on the mind-reading impairments of young adults with autism spectrum disorder (ASD). The hypothesis is that differences in mind-reading abilities between subjects with ASD and control subjects become more apparent when they have to infer thoughts and feelings of other persons in a less structured or more chaotic conversation, than when they have to do so in a more ...
