✍️🏻روش المان محدود (Finite Element Method) – مبانی و کاربردها
در بیومکانیک، سیستم‌های زیستی اغلب دارای ساختارهای پیچیده، ناهمگن و غیرخطی هستند که تحلیل آن‌ها با روش‌های تحلیلی دشوار یا غیرممکن است. روش المان محدود، با تقسیم یک ساختار پیچیده به المان‌های کوچک‌تر (مش‌بندی)، حل معادلات حاکم را به صورت عددی انجام می‌دهد و نتایج دقیقی از توزیع تنش، کرنش، جابجایی و دیگر پارامترهای مکانیکی ارائه می‌دهد.

"Like the bombing of the maternity ward in Mariupol," he said, "Even before it hits the news, you see the videos on the Telegram channels." The picture was mixed overseas. Hong Kong’s Hang Seng Index fell 1.6%, under pressure from U.S. regulatory scrutiny on New York-listed Chinese companies. Stocks were more buoyant in Europe, where Frankfurt’s DAX surged 1.4%. As such, the SC would like to remind investors to always exercise caution when evaluating investment opportunities, especially those promising unrealistically high returns with little or no risk. Investors should also never deposit money into someone’s personal bank account if instructed. "We're seeing really dramatic moves, and it's all really tied to Ukraine right now, and in a secondary way, in terms of interest rates," Octavio Marenzi, CEO of Opimas, told Yahoo Finance Live on Thursday. "This war in Ukraine is going to give the Fed the ammunition, the cover that it needs, to not raise interest rates too quickly. And I think Jay Powell is a very tepid sort of inflation fighter and he's not going to do as much as he needs to do to get that under control. And this seems like an excuse to kick the can further down the road still and not do too much too soon." What distinguishes the app from competitors is its use of what's known as channels: Public or private feeds of photos and videos that can be set up by one person or an organization. The channels have become popular with on-the-ground journalists, aid workers and Ukrainian President Volodymyr Zelenskyy, who broadcasts on a Telegram channel. The channels can be followed by an unlimited number of people. Unlike Facebook, Twitter and other popular social networks, there is no advertising on Telegram and the flow of information is not driven by an algorithm.
