The Estimate of Instantaneous Solar Radiation Intensity Using Energy Conversion Method

buckling of viscoelastic composite plates using the finite strip method

در سال های اخیر، تقاضای استفاده از تئوری خطی ویسکوالاستیسیته بیشتر شده است. با افزایش استفاده از کامپوزیت های پیشرفته در صنایع هوایی و همچنین استفاده روزافزون از مواد پلیمری، اهمیت روش های دقیق طراحی و تحلیل چنین ساختارهایی بیشتر شده است. این مواد جدید از خودشان رفتارهای مکانیکی ارائه می دهند که با تئوری های الاستیسیته و ویسکوزیته، نمی توان آن ها را توصیف کرد. این مواد، خواص ویسکوالاستیک دارند....

Solar energy conversion

energy—enough to power the great oceanic and atmospheric currents, the cycle of evaporation and condensation that brings fresh water inland and drives river flow, and the typhoons, hurricanes, and tornadoes that so easily destroy the natural and built landscape. The San Francisco earthquake of 1906, with magnitude 7.8, released an estimated 1017 joules of energy, the amount the Sun delivers to ...

Solar Energy Conversion into H2 Energy Using Ferrites

A cation-excess (Ni,Mn) ferrite N~o.~zMno.51Fe2.0504.0 with a single phase was synthesized by heating the mixture of corresponding metal salts and oxide in 5% 02175% C02120% N2 gas mixture for 18h at 1100C. It could be thermochemically activated to form a cation-excess ferrite Nio,5z~l+s~Mno.51~l+6~Fe2~05~1+6~0440 in N2 gas at elevated temperature: The ( value was 0.03 1 at 1100C. The activated...

Solar Energy Potentials and Radiation Map of Lorestan Province

Solar energy is the most unique renewable energy source in the world and is the main source of all energy on Earth. Solar energy can be converted into other forms of energy directly and indirectly. In general, the energy given off by the sun about 3. 8 two 1023 kW per second. In the present study, the potential of solar energy in the province of surveillance data 9 synoptic stations located in ...
