A Data Replenishment Method for Self Regulating Sail-Assisted Ships Considering Big Data
The concept of intelligent sail-assisted ships based on big data comes to people's mind gradually. Data loss and distortion cannot be avoided during data collecting and preprocessing process. In this paper, a data replenishment method based on computational fluid dynamics (CFD) method is proposed and simulation cases are done to explain the method
OPERATING PERFORMANCE OF A SAIL EQUIPPED TANKER IN WAVES AND WIND
Ship stability and the effect of sails on rolling have been studied in a newly-built, engine-powered, sail-assisted merchant ship. It was found that sail-damping may reduce the rolling angle in heavy rolling induced by waves.
The history and development of the dental surveyor--Part III.
The dental surveyor is an indispensable instrument capable of performing a number of prosthodontic procedures. Surprisingly, the technique of surveying casts as part of the treatment planning procedure did not emerge until early in the twentieth century. This article reviews the origins and early use of the dental surveyor. It includes features common to all surveyors as well as the principal uses of these instruments.
