Background: This case-control study evaluated the diagnostic accuracy of Bender-Gestalt test (BGT) in identifying neuropsychological impairments individuals with drug abuse compared to healthy controls. Methods: A total 70 participants, comprising 52 and 18 controls, all a Glasgow Coma Scale (GCS) score greater than 15, were included study. Each participant completed BGT assess visual-motor impairments. Results: Individuals exhibited significantly more errors including rotation/reversal (P...
Abstract Trim control mechanisms such as interceptors and trim flaps have been widely used in recent years highspeed crafts for ride control. In spite of their extensive application, a few studies investigating the impact on planing craft performance, published. present study, hydrodynamic quality is investigated through application an experimental method. Two scaled-down models high-speed mono-hull catamaran are tested with without calm water at different heights to investigate effect drag...
In this study, the hydrodynamics and noise behaviour of marine propellers are examined through finite volume method under various operational conditions. The these studied both numerically experimentally, characteristic curves produced. Sheet cavitation inception development conditions also considered in order to understand impact different rotational speeds on propeller noise. Ffowcs Williams Hawkings equations used extract total sound pressure levels non-cavitating sheet cavitating...
This in-water experimental study deals with the effects of after-body on FIV response round and sharp edge cylinders. Different circular, square, diamond, right-angle isosceles triangular cross-sections are investigated. The cylinder is examined in four different symmetrical unsymmetrical configurations respect to incident flow. current towing tank experiments form a basis for feasibility cylinders energy converters. results indicate that flat side perpendicular flow have galloping type...
The controllable flaps and interceptors in planing crafts not only may reduce the resistance, but also could be designed to make a boat run at or near optimum attitude various environments, which results reduction both resistance vertical motion waves. Planing vessels suffer from porpoising instability violent high forward speeds. can used control of crafts. In present study, impact controlled on craft seakeeping quality is investigated through application experimental theoretical methods....
Purpose This study aims to present compatible computational fluid dynamics procedure for calculation of incompressible three‐dimensional time‐dependent flow with complicated free surface deformation. A computer software is developed and validated using a variety academic test cases. Design/methodology/approach Two fluids are modeled as single continuum property jump at the interface by solving scalar transport equation volume fraction. In conjunction, conservation equations mass momentum...
