The values of the parameters r, t, St, T , and K used to price a call option via the Black-Scholes formula can be easily obtained from market data. Estimating the volatility coefficient σ can be a more difficult task, and several estimation methods are considered in this section with some examples of how the Black-Scholes formula can be fitted to market data. We cover the historical, implied, a...

از جمله استفاده فرآیند متالورژی پودر، ساخت فیلترهای فلزی و نیز فیلترهای فولادی است و همانطور که از نامشان پیداست این قطعات متخلخل هستند. فیلترها در حوزه های مختلف صنایع متالورژی، شیمیایی، داروسازی، فضائی و هوائی کاربرد و مورد استفاده وسیع قرار دارند. در این تحقیق، نمونه هائی متخلخل از پودر فولاد 316L تهیه شده بروش اتمایزینگ آبی طی فرآیند متالورژی پودر تهیه شدند. ابتدا پودرهای فولاد 316L ب...

A 12-lead ECG was obtained from a 59-year-old man experiencing chest pain on his first postoperative day following a triple-vessel coronary artery bypass graft (CABG). Is this a single-lead ischaemia? (Fig. 1). The ST-segment elevation in V6 does not represent ischaemia. In fact, lead V6 was inadvertently connected to an epicardial pacing wire, recording a unipolar signal (Fig. 2). www.elsevier...

  Background :Disruption of anterior cruciate ligament (ACL) is a common ligamentous injury of the knee. The choice of graft for (ACL) reconstruction remains controversial. This prospective, randomized clinical trial aimed to compare clinical results of bone-patellar tendon-bone (BPTB) grafts and four-strand semitendinosus-gracilis (ST) grafts for ACL reconstruction over a 3-year follow-up inte...
