We apply the multilevel Monte Carlo method for option pricing problems using exponential Lévy models with a uniform timestep discretisation. For lookback and barrier options, we derive estimates of the convergence rate of the error introduced by the discrete monitoring of the running supremum of a broad class of Lévy processes. We then use these to obtain upper bounds on the multilevel Monte Ca...
Introduction In this work we propose novel sparse matrix ordering approaches based on hypergraph partitioning. The significance of hypergraph-partitioning-based (HP-based) ordering is three-fold. First, almost all of the successful nested dissection [6] tools [7, 9, 10] are based on multilevel graph partitioning tools [7, 8, 10] with some extra initial partitioning and refinement strategies spe...
یکی از پارامترهای مهم محیطهای پخش نوترون، طول نوترون حرارتی است. روش مرسوم محاسباتی استفاده کد MCNP برمبنای توزیع شار در محیط و برازش تابع ریاضی مربوطه بر آن این پژوهش، روشی نوین که مبنای کارت PTRAC است، ارایه شده پارامتر برای آبسبک اساس روشهای فوق محاسبه با مقادیر گزارش مراجع مقایسه گردیده تطابق خوبی نیز مشاهده حسن فوق، عدم نیاز به علاوه فرض میشود تا محل چشمه، فاصلهی کافی وجود دارد. مسأله...
Abstract. The North Ionian Gyre (NIG) displays prominent inversions on decadal scales. We investigate the role of internal forcing induced by changes in horizontal pressure gradient due to varying density Adriatic Deep Water (AdDW), which spreads into deep layers northern Sea. In turn, AdDW fluctuates according circulation NIG through a feedback mechanism known as bimodal oscillating system. se...
شرایط افروزش و اشتعال سوختهای گداخت هستهای در حضور ناخالصها، یکی از موارد مهمی است که طراحی قرصهای سوخت باید مورد توجه قرار گیرد. این مقاله اثر ناخالصی هسته سنگین طلا بر کلیه فرایندهای احتراق پلاسمای غیرتعادلی دوتریم- تریتیم مدل چهار دمایی آن شکل تابع توزیع انرژی رفتار فوتونها تأثیر میگذارد بررسی گرفته است. مطالعه شامل اثرات منفی سوخت، طول زمان تشکیل لکه داغ نتایج محاسبات عددی به دست آم...
The β(3)-adrenegic receptor (β(3)-AR) selectivity over β(1)- and β(2)-ARs has been the most important aspect for successful therapeutic agents for obesity and type-II diabetes, as the concomitant activation of β(1)- and β(2)-ARs would lead to undesirable side effects, such as increased heart rate. In order to explore the structural basis for the β-AR subtype selectivity of agonists and anatagon...
Linear Programming is a scientific method used for obtaining and determine the most optimal solution problem with given constraints. This technique useful guidance of quantitative decision-making in different fields such as business planning, industrial engineering, production firm to extent social physical sciences. research examines application linear programming product(s) that maximize(s) p...
We introduce a simple additive process for equity index derivatives. The model generalizes Lévy Normal Tempered Stable processes (e.g. NIG and VG) with time-dependent parameters. It accurately fits the volatility surfaces in whole time range of quoted instruments, including options small time-horizon (days) long (years). via its characteristic function. This allows using classical Fourier prici...
