Union Internationale des Chemins (UIC) defines the high-speed railway (HSR) as a system that contains infrastructure and rolling stock. The can be newly built dedicated lines enabled for trains to travel with speed above 250 km/h or upgraded conventional up 200 even 220 km/h. HSR requires specially increased power weight ratio must have an in-cab signalling traditional systems are incapable of

A tunneled planing craft is a high-speed boat with two tunnels over the hull bottom that are designed to improve vessel’s performance. Hydrodynamic performance of hulls in calm-water well-known, however, current information on wave conditions limited. In this study, different degrees freedom heave and pitch motions studied regular waves by using computational fluid dynamics (CFD) method based U...

The main purpose of this study was to develop interdisciplinary project-based learning and investigate the process and effectiveness of project-based learning involving undergraduate students in the Naval Architecture and Ocean Engineering in a college in Taiwan. The theme of this research project was “boat design and building.” This study used the revised PIPER (PIPER; Preparation / Implementa...

recently, incremental sheet metal forming (ismf) process as one of the new methods in rapid prototyping collection has been considered by researchers. this process is based on a defined path in cnc controller and applies a spherical-head tool that supplies the required pressure for sheet metal forming. despite affirmation of process ability in forming symmetric geometries, some of its aspects s...

In rowing, motor learning may be facilitated by augmented feedback that displays the ratio between actual mean boat velocity and maximal achievable mean boat velocity. To provide this ratio, the aim of this work was to develop and evaluate an algorithm calculating an individual maximal mean boat velocity. The algorithm optimised the horizontal oar movement under constraints such as the individu...
