The field of perceptual quality assessment has gone through a wide range of developments and it is still growing. In particular, the area of no-reference (NR) image and video quality assessment has progressed rapidly during the last decade. In this article, we present a classification and review of latest published research work in the area of NR image and video quality assessment. The NR metho...
osa (oxic settling anoxic) process is one of the sludge reduction methods. in this method an anaerobic reactor is placed in activated sludge recycling line for sludge reduction purpose. this method is getting popular because of possibility of its application in currently operating waste water treatment plants. in this research, the performance of osa process in sludge reduction in sbr was impro...
background and purpose: quality of life is a ubiquitous concept, and improving quality of life plays a pivotal role in the promotion of individual and social health. this parameter requires exclusive attention in case of students since quality of life remarkably affects learning and academic achievement.this study aimed to evaluate quality of life among the students of islamic azad university o...
In this paper we compare the overall image quality of 7 state-of-the-art denoising schemes, based on human visual perception. A psycho-visual experiment was set up in which 37 subjects were asked to score and compare denoised images. A perceptual space is constructed from this experiment through multidimensional scaling (MDS) techniques using the perceived dissimilarity and quality preference b...
in the case of iran with arid and semiarid climate and lack of freshwater, pay attention to water quality and its effective factors is necessary. karkheh watershed is more than 5 million hectares in area and with biggest soil dam in asia, which has widespread land use changes in last decades. the most important factors of water volume and water resources reduction are aridity and improper land ...
امروزه تخمین حرکت بلوک در تصاویر بر اساس روش هایی که تمام جزئیات را شامل می شوند، تبدیل به یک مبحث فراگیر در شاخه ی پردازش تصویر گشته است. چرا که از جمله ی روش هایی به حساب می آید که باعث فشردگی و کاهش حجم داده های تصویری می گردد. جهت تحقّق این هدف، الگوریتم های متفاوتی ارائه شده اند. الگوریتم های جستجوی محلی، جستجوی پیشگویانه و... که با توجه به نیاز مسأله انتخاب و مورد استفاده قرار می گیرند، از...
background : the aim of this study was to investigate the association between the two most commonly used generic and disease specific health-related quality of life (hrqol) measures in patients with chronic lung disease due to sm: medical outcomes study short form 36-item (sf-36) and st george's respiratory questionnaire (sgrq). methods : this is a secondary analysis of iranian chemical warfare...
وب سرویس ها نرم افزارهایی هستند که از xml برای انتقال اطلاعات بین نرم افزارهای دیگر از طریق پروتکل های معمول اینترنتی استفاده می کنند، به عبارت دیگر وب سرویس ها مولفه های نرم افزاری قابل دسترس بر روی پروتکل های مختلف هستند و برای برقراری ارتباط بین نرم افزارها مورد استفاده قرار می گیرند. تضمین کیفیت سرویس یکی از مباحث غیرکارکردی وب سرویس ها است . در شبکه های کامپیوتری و سایر شبکه های مخابراتی ...
photocatalytic reduction of carbon dioxide to formaldehyde was investigated on four semiconductor photocatalysts (fes, fes/fes2, nio and tio2). the reaction was carried out in continues flow of co2 gas bubbled into the reactor. semiconductor photocatalysts were characterized by x-ray diffraction (xrd) and diffuse reflectance spectroscopic (drs) methods. sulfide ion was used as hole scavenger. t...
this study on the design of pid controllers for flexible single-arm robot system optimizationpso method is focused so that the coefficients of the pid controller are reduced. in this study,pid controller and pso algorithm have been described and then by using matlab, pidcontrol was simulated. then by pso algorithm, attempts to reduce the pid coefficients are givenby simulation. finally pid coef...
