The Maeslantkering ("Maeslant barrier" in Dutch) is a storm surge barrier on the Nieuwe Waterweg, in South Holland, Netherlands. [1] It was constructed from 1991 to 1997. As part of the Delta Works the barrier responds to water level predictions calculated by a centralized computer system called BOS.
The Maeslant barrier is designed for very extreme floods (when the water level is predicted to be 3 metres or more above NAP in Rotterdam). On average, this occurs once every 10 years. When the Maeslant barrier is closed, the entrance to the old port of Rotterdam at Oude Haven is closed to all shipping for at least 24 hours. The dikes behind ...
In this case then, for European options without dividends, the binomial model value converges on the Black–Scholes formula value as the number of time steps increases. [ 4 ] [ 5 ] In addition, when analyzed as a numerical procedure, the CRR binomial method can be viewed as a special case of the explicit finite difference method for the Black ...
The turbines were installed in the eighth sluice channel from the southern end of the barrier, and started generating electricity to the Dutch grid in 2016. [13] The installation was reported to have cost around US$12.4 million, and was the largest tidal power project in the Netherlands. [12]
The function f is variously called an objective function, criterion function, loss function, cost function (minimization), [8] utility function or fitness function (maximization), or, in certain fields, an energy function or energy functional. A feasible solution that minimizes (or maximizes) the objective function is called an optimal solution.
A barrier system would be expensive, but the city's plan, covering many miles of vulnerable coastline, would be even more expensive. And some of the cost to shore up areas on the sides of the barriers are scheduled to be spent anyway, for example in dune-building projects on the Rockaway peninsula and on Staten Island. [39] [45]
The formula can be expressed: =, means monopoly price set by firms means the marginal cost of production The Lerner index measures the level of market power and monopoly power that a firm owned.The higher Lerner index indicated the more monopoly power allows a company have chance to establish prices that are higher than their marginal costs and ...
These quantities represent a smile cost, namely the difference between the price computed with/without including the smile effect. The rationale behind the above formulation of the Vanna-Volga price is that one can extract the smile cost of an exotic option by measuring the smile cost of a portfolio designed to hedge its Vanna and Volga risks ...
