Battery life is an increasingly urgent challenge for today's untethered VR and AR devices. However, the power efficiency of head-mounted displays naturally at odds with growing computational requirements driven by better resolution, refresh rate, dynamic ranges, all which reduce sustained usage time AR/VR For instance, Oculus Quest 2, under a fully-charged battery, can sustain only 2 to 3 hours...
بررسی فرایند الکتروفنتون به منظور تصفیه ی پساب شرکت پتروشیمی شازند و بهینه سازی عوامل موثر بر فرایند
هدف از این تحقیق بررسی کارایی فرایند الکتروفنتون و بهینه سازی پارامترهای موثر بر فرایند به کمک طراحی آماری به منظور تصفیه پساب شرکت پتروشیمی شازند میباشد.در این تحقیق تاثیر پارامترهای : زمان واکنش ، چگالی جریان، ph پساب ، نسبت (?ml h?_2 o_2)/( lit pw) و نسبت مولی (mol h_2 o_2)/(mol fe^(2+) ) بر حذف cod و color از پساب پتروشیمی تحت فرایند الکتروفنتون( با الکترود های آهن و آلومینیوم به طور جداگان...
A new nonlinear dimensionality reduction method for multi-spectral images was presented to solve the problem brought by high dimensionality of multi-spectral images during color reproduction. Firstly, according to the characteristics of human visual system, the CIE standard observer color matching functions were weighted to the source spectral reflectance and then a principal component analysis...
This paper presents the treatment of Acid green V by an electrochemical oxidation using Ti/RuO2 IrO2 TiO2 as anode and cathode and NaCl as supporting electrolyte in a tubular flow reactor under continuous single pass process. During the electrolysis, COD reduction, color removal, and energy consumption were investigated under different flow rates and current densities. The experimental results ...
Background: Distillery’s vinasse wastewater is problematic to be easily disposed of in environment due to its high BOD and COD content which imposes a great deal of costs on plant. The main aim of this scientific and applied research is reducing the organic load of distillery’s vinasse wastewater via concentration technology. Method: In this research, concentration of vinasse technology was...
A conventional image posterization method occasionally fails to preserve the shape and color of objects due to the uneffective color reduction. This paper proposes a new image posterizartion method by using modified color quantization for preserving the shape and color of objects and color contrast enhancement for improving lightness contrast and saturation. Experiment results show that our pro...
