RISA Computational Fluid Dynamics Investigation Comparing the Performance of an Alternative Valvetrain Design Against a Traditional Poppet Valvetrain
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The poppet valve is by far the most widely used in cylinder head design of internal combustion (IC) engines; however, poppet valves themselves create significant flow restrictions during both the intake and exhaust strokes, ...
Approach to Automation of Line Heating by Combination of Reinforcement Learning and Finite Element Method Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In recent years, ship hulls have very complicated shapes in order to reduce frictional resistance and wave resistance during navigation. In particular, in the bow and stern, curved skin plates with complex shapes are used. ...
Automatically Landing an Unmanned Aerial Vehicle Using Perspective-n-Point Algorithm Based on Known Runway Image: Area Localization and Feature Enhancement With Time Consumption Reduction
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This research proposes a method to track a known runway image to land an unmanned aerial vehicle (UAV) automatically by finding a perspective transform between the known image and an input image in real-time. Apparently, ...
Large Amplitude Free and Forced Vibrations of Functionally Graded Timoshenko Beams Using Coupled Displacement Field Method
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The large amplitude vibrations of functionally graded (FG) beams consisting of metal rich layers at the bottom, ceramic rich layers at the top, and a concentrated mass at the mid-span have been studied using coupled ...
The Importance of Transparency in Regulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The annual audit plan of the Office of the Inspector General (OIG) of the Nuclear Regulatory Commission (NRC), which was issued in November 2020, included an audit of the NRC’s practice of allowing “dropin” visits. These ...
Design and Characterization of a Flexible Self-Inflating Mechanical Structure
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Inflatable structures are commonly used in a variety of engineering applications such as robotics, space structures, medical devices, and automotive safety devices. However, inflation in these systems often requires a ...
Adsorption of Volatile Organic Compounds Onto Biomass-Derived Activated Carbons: Experimental Measurement and Comparison
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Volatile organic compounds (VOCs) are a class of hazardous gaseous materials emitted from certain solids or liquids. They are thought to possess serious short- or long-term adverse effects on human health. Nowadays, an ...
On Topological Data Analysis for Structural Dynamics: An Introduction to Persistent Homology
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Topological methods can provide a way of proposing new metrics and methods of scrutinizing data, that otherwise may be overlooked. A method of quantifying the shape of data, via a topic called topological data analysis ...
Propulsion Cost Changes of UltraLightweight Manual Wheelchairs After One Year of Simulated Use
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Manual wheelchairs are available with folding or rigid frames to meet the preferences and needs of individual users. Folding styles are commonly regarded as more portable and storable, whereas rigid frames are commonly ...
Product Competition Prediction in Engineering Design Using Graph Neural Networks
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Understanding relationships between different products in a market system and predicting how changes in design impact their market position can be instrumental for companies to create better products. We propose a graph ...
