attempts have been made to study the thermodynamic behavior of 1,3 butadiene purification columns with the aim of retrofitting those columns to more energy efficient separation schemes. 1,3 butadiene is purified in two columns in series through being separated from methyl acetylene and 1,2 butadiene in the first and second column respectively. comparisons have been made among different therm...
one of the most important goals for increasing recognition and treatment revenue is transmitting vital data to medical care team, more quickly. nowadays, use of new technologies for transmitting data will deploy more and more daily. in this article, for transmitting electrocardiogram, first we code the signal into a suite of codes, then we will use bluetooth technology to transmit data from off...
Let S ( t ) denote the argument of Riemann zeta-function, defined as = 1 π Im log ζ / 2 + i . Assuming hypothesis, we prove that Ω ± This improves classical Ω-results Montgomery (Theorem 2; Comment. Math. Helv. 52 (1977) 511–518) and matches with Ω-result obtained by Bondarenko Seip Ann. 372 (2018) 999–1015).
In recent years there has been an increase in the number of inactive and debris Space Objects (SOs). This work examines both data driven and model driven SO classification. The model driven approach investigated for this work is based on the Multiple Model Adaptive Estimation approach to extract SO characteristics from observations while estimating the probability the observations belonging to ...
Background: Dyes have complicated structure, are usually toxic and resistant to biological treatment which entere into environment by industrial waste streams. The aim of this study was the removal of reactive red 198 dye (RR 198) by photolysis (UV) and photocatalytical (TiO2/UVC) processes. This study was conducted to investigate the effects of dye concentration, pH, TiO2 dose, and contact tim...
Optimal crop water requirement is needed for precise irrigation scheduling. Prediction of crop water requirements is a basic factor to achieve this goal. In this study, maize potential evapotranspiration (ETp) was prediced by maize simulation model (MSM). Then, it was evaluated and validated using experimental field data obtained in Agricultural Research Station of Shiraz University (Bajghah, F...
