Prediction of Resistance and Self-Propulsion Characteristics of a Full-Scale Naval Ship by CFD-Based GEOSIM Method

open access: yes, 2020
Resistance and self-propulsion characteristics of a naval ship at full scale have been investigated by using Telfer's GEOmetrically SIMilar (GEOSIM) method based on the computational fluid dynamics (CFD) approach.

Unnatural Wills: Inheritance Disputes and Inequality

open access: yesThe British Journal of Sociology, EarlyView.
ABSTRACT Within the conceptual frame of relational economic sociology, inheritance disputes are a canonical form of relational mismatch. But the social patterning of relational mismatches, and their various ties to inequality, remain murky. In this paper, I examine all known inheritance disputes in Dallas from 1895–1945 within their social context to ...

An Approximate Method for Calculation of Mean Statistical Value of Ship Service Speed on a Given Shipping Line , Useful in Preliminary Design Stage

open access: yesPolish Maritime Research, 2015
During ship design, its service speed is one of the crucial parameters which decide on future economic effects. As sufficiently exact calculation methods applicable to preliminary design stage are lacking the so called contract speed which a ship reaches

Genetic programming for the automatic design of controllers for a surface ship [PDF]

open access: yes, 2008
In this paper, the implementation of genetic programming (GP) to design a contoller structure is assessed. GP is used to evolve control strategies that, given the current and desired state of the propulsion and heading dynamics of a supply ship as ...

Market Integration and Nonlinear Price Transmission in 19th‐Century British Wheat Markets

open access: yesJournal of Agricultural Economics, EarlyView.
ABSTRACT Important developments in infrastructure and institutions characterized 19th‐Century wheat markets in Great Britain. Among these developments was the construction of the national rail system which enabled cheaper and more efficient transport of grain and other bulky cargoes between inland towns and ports.
