Rainfall data are widely used to predict regional rainfall. Limited rainfall is a problem that has an impact on decreasing accuracy, one of which in the area South Sumatra. This can be overcome by using satellites. However, utilize satellitebased data, it necessary carry out analysis determine accuracy data. research aims evaluate from GPM satellite and PERSIANN with validation calibration so v...
Evaluating the quality of satellite precipitation products (SPPs) is crucially important for SPPs' applications and improvements. This study aims to comprehensively evaluate accuracy six widely used SPPs (GSMaP, IMERG, TMPA, CMORPH, PERSIANN, CHIRPS) from 2000 2017 over mainland China using 2372 rain gauges. The performance at different spatio-temporal scales altitudes are explored. probability...
پنل های خورشییدی دارای مشیه ه جریان -ولتاژ غیر خطی بوده و تنها در یک نقطه کار خاص، حداکثر توان را تولید می کنند. این نقطه بهینه توان با تغییر دما و شیدت نور تغییر می کند. روش های مهتلفی برای ردیابی نقطه حداکثر توان به صورت free model و based model معرفی شده است. این تحقیق روش جدیدی جهت بهبود عملکرد ردیابی نقطه حداکثر توان پنل های خورشیدی جدا از شبکه ارائه می دهد و الگوریتم روش پیشینهادی از دو...
Tersedianya data hujan yang lengkap serta akurat menjadi sebuah kebutuhan perlu dipenuhi namun pada kenyataan di lapangan, banyak ditemukan kasus ketidak lengkapan pendataan hujan. Sehingga dilakukan kajian mendalam mengenai keterkaitan terukur dengan dari satelirt disajikan oleh beberapa satelit. Penelitian ini tujuan agar mengetahui korelasi antara BMKG dan satelit PERSIAN-CDR & TRMM 3B42...
run-out-table (rot) is located between last finishing stand and down coiler in a hot strip mill. as the hot steel strip passes from rot, water jets impact on it from top and bottom and strip temperature decreases approximately from 800-950 °c to 500-750°c. the temperature history that strip experience while passing through rot affects significantly the metallurgical and mechanical properties, s...
the main purpose of this research was to:1.develop a coking model for thermal cracking of naphtha.2.study coke inhibition methods using different coke inhibitors.developing a coking model in naphtha cracking reactors requires a suitable model of the thermal cracking reactor based on a reliable kinetic model.to obtain reliable results all these models shall be solved simultaneously.for this pu...
Insufficient precipitation observations hinder the bias-correction of Global Climate Model (GCM) outputs in ungauged and remote areas. As a result, reliability future water resource projections is restricted for these Open-access quantitative estimation (QPE) products offer potential solution to this challenge. This study assesses effectiveness three widely used, long-term QPEs, including ERA5,...
Drought is a climatic event that threatens the environment and human life with an ambiguity of location time. Recently, droughts can be analyzed for different periods help mathematical methods developing technology. This study aims to perform drought analysis in 126 designated points Turkey. The data includes monthly total precipitation values between March 2000 February 2021, obtained from PER...
Satellite-based precipitation (SP) data are gaining scientific interest due to their advantage in producing high-resolution products with quasi-global coverage. However, since the major reliance of is on distinctive geographical features each location, they remain at a considerable distance from station-based data. This paper examines effectiveness convolutional autoencoder (CAE) architecture p...
