Parametric modelling of marine structures for hydrodynamic calculations

Ocean Engineering, 2018
Abstract The paper describes a numerical 3D modelling method to develop quadrilateral meshes for panel method calculations with an integrated solution to obtaining the mass properties from the same grid. It aims to offer a more precise and versatile alternative to the spreadsheet type approach repeatedly used in early design stages of marine ...

Calculation of the Principal Characteristics of a Parametric Radiating Antenna

LETI Transactions on Electrical Engineering & Computer Science
Presents the calculation of the main characteristics of the parametric radiating antenna for the given signals with pumping frequencies of 86 kHz for a tone signal, 87...97 kHz for a signal with linear frequency modulation (LFM) and a signal with a difference frequency of 1..11 kHz (LFM signal).

Statistically calculating reject limits at parametric test

Twenty First IEEE/CPMT International Electronics Manufacturing Technology Symposium Proceedings 1997 IEMT Symposium, 2002
Known Good Die (KGD) methodology is a process used in the manufacture of semiconductor chips which determines reject limits for parameters measured at sample probe. The philosophy of KGD is to set reject limits on all sample probe parameters at x~/spl plusmn/4 s, where x~ is the sample average and s is the sample standard deviation, assuming a normal ...

A Desktop Calculator for Parametric Fuzzy Arithmetic. [PDF]

, 2009
In this paper we describe a desktop calculator for the fuzzy arithmetic and the fuzzy extension of basic univariate functions. The fuzzy numbers are modelled indifferently in the parametric LR or LU representation. The operations are performed in the setting of Zadeh's extension principle.

On the Correlation Approach and Parametric Approach for CVA Calculation

SSRN Electronic Journal, 2016
Credit value adjustment (CVA) is an adjustment added to the fair value of an over-the-counter trade due to the risk of counterparty defaults. When the exposure to the counterparty and the counterparty default risk tend to change in the same direction, the so-called wrong-way risk (WWR) must be taken into account.

Parametrization and Calculation of a Shaft by Using Mathematical Applications

2017
It is advisable to carry out parametric calculation and make parametric 3D model for machine parts which undergo frequent changes of initial applications of both the structure and the load. It was found that designers spend most of their time adapting the existing models. This paper presents an example of calculation of gear reducer shaft.

Implementing calculations of solar gains in parametric models

2009
Working with environmentally sustainable architecture today is becoming more and more challenging due to the strict energy demands in the building regulations (Hyde et al. 2007). This demands a design process, where parameters affecting the energy demands are considered from the very beginning, and where relations between the architectural form, the ...

Calculation of the Differential Geometry Properties of Implicit Parametric Surfaces Intersection

2020
Generally, to calculate the Frenet-Serret apparatus of a curve, it is necessary to have a parameterization of it; but when it is difficult to obtain a parameterization of the curve, as is the case of the curves obtained by the intersection of two implicit parametric surfaces, it is necessary to develop new methods that make it possible to know the ...
