one of the main objectives of ecosystem management is to preserve the speciesdiversity. many researchers regard higher species diversity as the stability of ecologicalsystems. the aim of this study is to investigate the stability and relationships betweentopographical factors with diversity indices in ghorkhud mountainous rangeland innorthern khorasan province, iran. for data sampling (2012), l...
We propose an equation to evaluate the efficiency of a classification as function effort required and population size data collectors. The formula postulates “classification coefficient”, which relates not only complexity object be classified, but also availability representativeness. When applied phytocoenoses, suggests that system based on vascular plants offers best compromise between sampli...
تحقیقات اخیر روی روشهای عددی، بر ایده استفاده از روشهای بدون شبکه{meshfree methods} برای حل عددی معادلات دیفرانسیل با مشتقات جزئی تاکید می کند. یکی از ویژگی های رایج همه روشهای بدون شبکه، توانایی آنها در ساخت تقریب تابع، تنها با استفاده از اطلاعاتی در یک مجموعه از داده های پراکنده می باشد. تعدادی از روشهای بدون شبکه عبارتند از: روش هیدرودینامیکهای ذره ی هموار{smooth particle hydrodynamics ...
in this thesis a calibration transfer method is used to achieve bilinearity for augmented first order kinetic data. first, the proposed method is investigated using simulated data and next the concept is applied to experimental data. the experimental data consists of spectroscopic monitoring of the first order degradation reaction of carbaryl. this component is used for control of pests in frui...
هدف از ارایه این پایان نامه بررسی روشی است برای حل معادلات دیفرانسیل غیرخطی که شکل عمومی آنها بصورت lu+nu=g(t) می باشد. در این معادله n یک عملگر غیرخطی و l یک عملگر دیفرانسیلی خطی می باشد. این روش تحت عنوان روش تجزیه (آدومیان) بررسی می شود. در این روش u رابه صورت u تجزیه می کنیم. همچنین ترکیب غیر خطی nu را بصورت an (u , u , ... , u ) نمایش می دهیم که a ها چند جمل...
a simple, rapid and low-cost scanner spectroscopy method for the glucose determination by utilizing glucose oxidase and cdte/tga quantum dots as chromoionophore has been described. the detection was based on the combination of the glucose enzymatic reaction and the quenching effect of h2o2 on the cdte quantum dots (qds) photoluminescence.in this study glucose was determined by utilizing glucose...
