Added Resistance & Drift Force Analysis in Regular and Irregular Waves
The sea wave causes excess resistance which is out of scope of calm water resistance. The total wave force in horizontal plane is divided into “Added Resistance” and “Drift Force”. In this study, based on Gerritsma and Beuckelman[3] hypothesis a computer program has been developed for calculation of added resistance and drift force at various ship speeds and various head...
متن کاملAnalysis of hydrofoil craft in regular and irregular waves
In this article, the most important specifications of hydrofoil floats, i.e. their seakeeping under regular and irregular waves under different encounter angles of wave, has been investigated. Numerical simulation has been done using STAR CCM+ software. Surge, heave, roll and pitch motions are kept free at the same time and their effects on each other are taken into account. USV01 model, whose ...
متن کاملFrequency response characteristics of sympathetically mediated vasomotor waves in humans.
In a recent study, we demonstrated that transmission from peripheral sympathetic nerves to vascular smooth muscles is strongest in the frequency band from 0.2 to 0.5 Hz in conscious rats. In contrast, sympathetic modulation of vasomotor tone in humans is suggested to be reflected in the power spectrum of arterial blood pressure in a frequency range centered around ∼0.1 Hz. Therefore, we address...
متن کاملInfluence of Tether Length in the Response Behavior of Square Tension Leg Platform in Regular Waves
The tension leg platform (TLP) is a vertically moored structure with excess buoyancy. The TLP is regarded as moored structure in horizontal plan, while inherit stiffness of fixed platform in vertical plane. In this paper, a numerical study using modified Morison equation was carried out in the time domain to investigate the influence of nonlinearities due to hydrodynamic forces and the coupling...
متن کاملRegular frequency computations
An (m,n)-computation of a function f is given by a deterministic Turing machine which on n pairwise different inputs produces n output values where at least m of the n values are in accordance with f . In such a case we say that the Turing machine computes f with frequency ≥ m/n. The most prominent result for frequency computations is due to Trakhtenbrot: The class of (m,n)-computable functions...
