The Welfare Effects of Fuel Conservation Policies in the Indian Car Market
Indian Car Market Fuel Conservation Policies
2015/9/18
We estimate a model of vehicle choice and miles driven to analyze the impact of fuel
conservation policies in the Indian car market. Taxing diesel fuel to equalize diesel and petrol prices
would red...
The Experiment and Numerical Calculation of Propeller Performance with Surface Roughness Effects
Propeller Performance Surface Roughness Boundary Layer
2009/5/18
As well known, propeller and hull of ship are fouled and their surface are roughened due to various causes such as adhesion of sea-lives, painting degradation, cavitation erosion etc. The surface roug...

High-Speed Planing Craft Resistance Test Scale Effects Drag Force Lift Force Frictional Resistance Residual Resistance Transom Stern
2009/5/18
In order to develop a resistance test method for high speed planing craft using a very small model, the scale effects on wetted surface area, frictional resistance and pressure forces acting on a smal...
Wave Making Resistance of Ships in Shallow Water Based on Second Order Free Surface Condition with Sinkage and Trim Effects
Resistance Boundary Element Method Shallow Water Morino Perturbation Method Free-Surface Flow
2009/5/12
The problem of free surface potential flow around a ship in shallow water is subjected to linearized form of free surface condition and kinematic conditions on the body and bottom surface. The solutio...
A Study of On-Board Monitoring and Analysis System of Ship Propulsion Performance-An Estimation Method of Propeller Performance with Surface Roughness Effects
Propeller Performance Surface Roughness Ship Propulsion Performance Monitoring
2009/5/12
The propulsion performance of actual ship at sea tends to deteriorate mainly due to the fouling of hull and propeller. It is important, therefore, to monitor the present situation of ship propulsion p...
Effects of sway motion on roll reduction performance of an Anti-Rolling Tank
sway motion roll reduction performance Anti-Rolling Tank
2009/4/30
Effects of sway motion on roll reduction performance of a U-tube-type anti-rolling tank are experimentally investigated. Forced rolling and swaying tests of an anti-rolling tank model show that the w...

Compressive Plastic Zone the Fatigue Crack Tip Propagation Behavior
2009/4/30
In this paper, emphasis on physical meanings of hysteresis loops denoting a relationship between loads and strains near the fatigue crack tip, variations of the tensile plastic load zone in loading an...
A Study on Viscous Effects of Roll Damping for Multi-Hull High-Speed Craft
Viscous Effects Roll Damping Multi-Hull High-Speed Craft
2009/4/29
The roll damping plays a very important part of amplitude of roll motion in resonance and trigger of parametric rolling of a ship. Since the viscous damping components are usually dominant in the roll...
A study on the shielding effects among wind-power generators in a floating wind farm
wind-power generators shielding effects floating wind farm
2009/4/29
In the present study, the shielding effects among the generators in an offshore floating wind farm are investigated through extensive experiments and the trade-off effects on the generation cost due t...
Method of Estimation for Tensile Residual Stress Effects on Brittle Fracture Initiation
brittle fracture Tensile Residual
2009/3/27
This paper studies the method for estimating the residual stress effect on brittle fracture of structural steel based on the Weibull stress criterion. Using 4-point bend specimens, tensile residual st...
