RISDecision Support System for Railway Track Maintenance and Renewal Management
Publisher: American Society of Civil Engineers
Abstract: This paper describes a decision support system approach for railway track maintenance and renewal management system to analyze the track components and to suggest methods for helping the track managers and engineers decide ...
Model to Estimate Trip Distribution: Case Study of the Marmaray Project in Turkey
Publisher: American Society of Civil Engineers
Abstract: Istanbul, the only city that straddles two continents, Europe and Asia, is one of the biggest metropolitan areas in the world with over thirteen million residents. The demand for transportation in Istanbul has been boosted ...
Effects of Errors in Coordinates on Transformation Parameters
Publisher: American Society of Civil Engineers
Abstract: In the stage of transformation of global positioning system coordinates to a national coordinate system, the transformation parameters computed show local changes depending upon the selection of common points used in the ...
Experimental Study on the Bond Strength of Different Geometries of Corroded and Uncorroded Reinforcement Bars
Publisher: American Society of Civil Engineers
Abstract: This study develops empirical models for the prediction of the bond strength of uncorroded and corroded reinforcement bars. The effects of hooked reinforcement on the bar’s development length when covered fully and partially ...
Centrically Loaded Bolt Joints
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Externally loaded bolt joints of different design are investigated. The bolt load is substantially lower than that predicted by the mounting stiffnesses of bolt and abutment. A load application ...
Control of Charge Dilution in Turbocharged Diesel Engines via Exhaust Valve Timing
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper we extend an existing crank angle resolved dynamic nonlinear model of a six-cylinder 12 l turbocharged (TC) Diesel engine with exhaust valve closing (EVC) variability. Early EVC ...
Material and Microslip Damping in a Rotor Taking Gravity and Anisotropic Bearings Into Account
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The paper is concerned with material and microslip damping in a rotor. The horizontal rotor is carried by anisotropic bearings, which means that the shaft feels three different frequencies, the ...
Exergetic Analysis and Assessment of Industrial Furnaces
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This study presents exergy analysis of a natural gas-fired radiant tube-heating furnace. In the analysis, actual data over a test period of 3 h were used. Exergy efficiencies, destructions, ...
Computation of the Pressure Distribution in Hydrodynamic Bearings Using Newton’s Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper an algorithm is developed where Reynolds’ equation, equilibrium equations and non-negativity of pressure are formulated as a system of equations, which are not differentiable in ...
Virtual Tissue Cutting With Haptic Feedback Using a Hybrid Actuator With DC Servomotor and Magnetorheological Brake
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Surgical training is an important and recent application where haptic interfaces are used to enhance the realism of virtual training simulators. Tissue cutting with surgical scissors is a common interaction mode in the ...
