Facial structure editing of portrait images is challenging given the facial variety, lack ground-truth, necessity jointly adjusting color and shape, requirement no visual artifacts. In this paper, we investigate how to perform chin as a case study structures. We present novel method that can automatically remove double effect in images. Our core idea train fine classification boundary latent sp...
در این پژوهش دو نوسان ساز کنترل شده با سیگنال دیجیتالی بر مبنای دو تکنیک مختلف طراحی این نوسان سازها یکی بر مبنای تغییر قدرت جریان دهی mos و دیگری بر مبنای تغییر خازن بار طراحی شد. نوسان ساز مبتنی بر تغییر قدرت جریان دهی با استفاده از معکوس کننده های مبتنی بر اشمیت تریگر و آرایه ترانزیستورهای موازی جهت بهبود توان مصرفی تحقق یافت. همچنین مداری برای بهبود خطسانی آن در کدهای دیجیتال ورودی بالا ارا...
in the industrial area of elefsis, greece, aerosol samples from the atmosphere were collected using a stacked filter unit sampler, which separates the airborne particulate matter into coarse (pm2.5-10) and fine (pm2.5) size fractions. the samples collected during the period january 2005 to march 2006, were analyzed by anodic stripping voltammetry (asv) and inductively coupled plasma atomic emis...
the increasing use of nitrogen fertilizers due to high dynamics of nitrate in the soil would be a serious threat to groundwater, and therefore, to thuman health. this study is aimed to investigate the disperdivity values of nitrate in the coarse, medium and fine sandy soils in the short travel distance of 20, 40 and 80 cm in vitro using the hydrus-1d model. for this purpose, pure potassium nitr...
In order to design, manufactur and use chewing activity automatical recorder and more accurate assessment of livestock nutrition from 8 Holstein dairy cattle were used with similar production, weight, age, breed and health in change over design 2×2 in two 21-day periods (2 weeks to adapt to the diet and 7 days for sampling). Treatments were 2 diets with the same chemical composition and differe...
We study visual selection: Detect and roughly localize all instances of a generic object class, such as a face, in a greyscale scene, measuring performance in terms of computation and false alarms. Our approach is sequential testing which is coarse-tone in both in the exploration of poses and the representation of objects. All the tests are all binary and indicate the presence or absence of loo...
Among different types of controlling systems, the ON/OFF digital relative humidity control was used for measuring electrical properties of cashmere fibers to make the ambient relative humidity fixed. To achieve this goal the required hardware and software were designed and fabricated. The electrical resistance of fine and coarse hair cashmere fiber was measured by charge and discharge condenser...
Soil surface roughness (SSR) is one of the important factors in wind and water erosion studies and control. Several parameters such as surface rock fragments influence SSR. Main objectives of this paper are to study and compare (Allmarass) random roughness (RR) and tortuosity (Tb) indices in coarse, medium and fine grain plains of Yazd-Ardakan and investigate the relationship between indices an...
In recent years, due to the overpopulation, serious water shortages, and need to consume more water, the use of wastewater treatment plant has attracted lots of attention. When the pollution load is not high, biofilm reactors are commonly used for the purpose. In this study, the porous concrete as a bed biofilm in reducing pollution load of wastewater was investigated. In order to evaluate poro...
An experiment was carried out to determine the effect of corn silage particle size and fat supplements on performance, solid passage rate through the digestive tract, and chewing behavior in dairy cows. The forages were coarse or fine corn silage with geometric means of 8.8±2.7 and 5.6±2.8 mm, and alfalfa with geometrics means of 7.0±3.3 mm, and fat supplements were neutral fat (palm) and soy-o...
