طوفان‌های گردوغبار بلایایی طبیعی‌اند که در زندگی انسان و محیط‌زیست تأثیر چشمگیری گذاشته‌اند. توسعة مدل‌هایی، به‌منظور پیش‌بینی مسیر حرکت این طوفان‌ها، پیشگیری مدیریت نقش بسزایی ایفا می‌کند زیرا انتقال آنها را آشکار مناطق آسیب‌پذیر بعدی برابر طوفان مشخص می‌کنند. به‌لطف امکانات روش‌های یادگیری عمیق حل مسائل مبتنی‌بر سری زمانی یافتن الگوهای پنهان از حجم دادة کلان، پژوهش، یک مدل ترکیبی شبکة عصبی پی...

PPG12-Buteth16, PPG-9-Buteth12, PPG-26-Buteth-26, and PPG-28-Buteth-35 are polyoxypropylene, polyoxyethylene ethers of butyl alcohol that function as hair conditioning agents, miscellaneous skin conditioning agents, surfactant/emulsifying agents. In addition, PEG-12-Buteth-16 is used as a solvent in cosmetic formulations. This latter ingredient is used at concentrations up to 31% in hair groomi...

High prevalence of obstructive sleep apnea (OSA) has increased the demands for more convenient and accessible diagnostic devices other than standard in-lab polysomnography (PSG). Despite the increasing utility of photoplethysmograph (PPG), it remains understudied in underserved populations. This study aimed to evaluate the reliability of a standard pulse oximeter system with an automated analys...

Preformed particle gel (PPG) has been successfully synthesized and applied to control excess water production in most of the mature, waterflooded oil fields in China. This paper reports on laboratory experiments carried out to investigate PPG transport mechanisms through porous media. Visual observations in etchedglass micromodels demonstrate that PPG propagation through porous media exhibits s...

A photoplethysmography (PPG) signal provides very useful information about a subject's hemodynamic status in a hospital or ubiquitous environment. However, PPG is very vulnerable to motion artifacts, which can significantly distort the information belonging to the PPG signal itself. Thus, the reduction of the effects of motion artifacts is an important issue when monitoring the cardiovascular s...

Liquid -caprolactone (CL) oligomers were synthesized by a ring-opening reaction of CL using a propylene glycol (PPG) as the initiator for use as new plasticizers of poly (L-lactide) (PLA) films. PPG-CL oligomers containing two (PPG-2CL) and four (PPG-4CL) units of CL at both PPG end-chains were prepared. The PLA/oligomer blend films were prepared by solution blending before film casting. The t...
