Millimeter-wave (mmWave) communication included in new radio (NR) provides high throughput to meet the stringent requirements of modern applications. However, its performance is highly dependent on whether obstacles are blocking line-of-sight (LOS) paths. Blockages LOS paths jeopardize reliable connections. E-UTRA-NR dual connectivity (EN-DC) one option for managing unstable using robust long-t...

conclusions results indicated that annular fluidized bed reactor’s adsorbers are useful techniques for vocs adsorption. comparison of two particle ranges indicates that in all concentrations and all flow rates of the experiments, smaller particle size adsorption are better. in superficial velocity above the minimum fluidization velocity, pressure drop of fluidized beds are less than the pressur...

A computational study of the blood flow in a stenosed microvessel is presented using coupled discrete ghost-cell and continuous-forcing immersed boundary methods. This focuses on studying platelet behaviors near stenosis with deformable red cells (RBCs). The influence varying hematocrit, area blockage, shape, driving force characteristics, RBCs, particle considered. Distinct characteristics are...

در حوزه مهندسی سواحل، شکست امواج در نزدیکی ساحل از اهمیت زیادی برخوردار است. یکی از مسائل مهم ناشی از شکست امواج پدیده انتقال رسوب است که اهمیت فراوانی در مهندسی سواحل و حفاظت سواحل دارد. در دهه های اخیر تلاش زیادی به منظور فهم بیشتر این پدیده انجام شده است. با وجود پیچیدگی رفتاری حرکتی سیال در هنگام شکست موج، مشکلات زیادی به منظور توصیف یک روش ریاضی برای مطالعه در مورد جریان سطح آزاد در پدیده ...
