SUMMARY Modelling the spatial distribution of infrasound attenuation (or transmission loss, TL) is key to understanding and interpreting microbarometer data observations. Such predictions enable reliable assessment source characteristics such as ground pressure levels associated with earthquakes, man-made or volcanic explosion properties, ocean-generated microbarom wavefields. However, computat...
assigning premium to the insurance contract in iran mostly has based on some old rules have been authorized by government, in such a situation predicting premium by analyzing database and it’s characteristics will be definitely such a big mistake. therefore the most beneficial information one can gathered from these data is the amount of loss happens during one contract to predicting insurance ...
به منظور بررسی تاثیر پروبیوتیک و سطوح مختلف پودر صمغ آنغوزه در مقایسه با آنتی بیوتیک (آویلامایسین) بر عملکرد رشد، وزن نسبی اندام های داخلی، میکروفلور روده، مورفولوژی پرزهای روده، کیفیت گوشت و تیترآنتی بادی بر علیه گلبول قرمزگوسفندی در جوجه های گوشتی، آزمایشی در قالب طرح کاملا تصادفی با 6 تیمار به اجرا درآمد. تیمارهای آزمایشی شامل: جیره پایه بدون افزودنی، جیره پایه حاوی 100 میلی گرم در کیلو گرم ...
This project bestows optimal sizing and placement of FACTS device, which is achieved by the searching method of bacteria foraging algorithm (BFA) with optimal sizing of FACTS device. Static Var Compensator (SVC) is one of the FACTS devices, utilized for progress of voltage profile and loss minimization. The precise strategy of SVC offers the real power loss minimization with increase of voltage...
In this study, the acoustic properties of porous absorbents with different porosity levels have been evaluated using different mathematical models. These models use one or more parameters of materials for calculating acoustic characteristics. In all of these models, materials are considered as equivalent fluid and reactionary characteristics have not been taken into account.
