RISSurvival of Biological Cells Deformed in a Narrow Gap
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Recent studies show that during slow freezing of biological cells, the cells may be also injured by not only chemical damage but also mechanical damage induced by ice crystal compression. A ...
Flow Control of Rotating Stall in a Radial Vaneless Diffuser
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The instabilities of a backflow layer on a diffuser wall and the main flow with vorticity have already been shown theoretically to cause the occurrence of rotating stall in a vaneless diffuser. ...
Application of Optimization Approach to Static FE Analysis of Hard Disk Drive Slider
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The objective of the present work is to present the numerical analysis of the computer hard disk slider. The air film pressure is calculated using the finite element method. The conjugate-gradient ...
Sequential Algorithm Based on Number Theoretic Method for Statistical Tolerance Analysis and Synthesis
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Tolerancing is one of the most important tasks in product and manufacturing process design. In the literature, both Monte Carlo simulation and numerical optimization method have been widely used ...
Control of Volumetric Flow-Rate of Ball Valve Using V-Port
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The control of volume flow rate in a ball valve is very important when a ball valve is utilized in a piping system. It is difficult to linearly control the flow rate in a ball valve ...
Skew Ray Tracing and Sensitivity Analysis of Geometrical Optics
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In order to improve upon the inconvenient and complicated contemporary analytic techniques employed for optical systems, this paper investigates two important optical topics: (1) the determination ...
An Analytical Representation of Chip Area for Corner-Radiused Tools Under Both Depth-of-Cut and Feed Variations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The operation of corner-radiused tools under both depth-of-cut and feed variation is a situation that occurs for many processes (e.g., straight turning, contour turning, boring, and face-milling) ...
Dynamic Analysis of a Mode I Propagating Crack Subjected to a Concentrated Load
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This work investigates the phenomenon of mode I central crack propagating with a constant speed subjected to a concentrated load on the crack surfaces. This problem is not a self-similar ...
Vibration Characteristics and Seismic Responses of Mechanical Structures With Hysteresis Elements
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Hysteresis elements such as elasto-plastic dampers are important for mechanical structures. They have nonlinearities and thus the vibration characteristics of mechanical structures with hysteresis ...
Identification of Armax Models With Time Dependent Coefficients
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A method that uses input/output measurements is developed for the estimation of the coefficients of stochastic Time-varying AutoRegressive Moving Average with eXogeneous imputs (TARMAX) models. The ...
