The Current Status of Hydrogen and Fuel Cell Development in China
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Potentially large amount of hydrogen resource in China could theoretically supply 100 × 106 fuel cell passenger cars yearly. The Chinese government highly values the hydrogen and fuel cell technology. Policies and plans ...
Deep Learning–Based Framework for Bridge Deck Condition Assessment Using Ground Penetrating Radar
Publisher: American Society of Civil Engineers
Abstract: Ground penetrating radar (GPR) is an advanced nondestructive testing (NDT) technique extensively used for assessing the structural integrity of concrete bridge decks. Despite its effectiveness, the manual interpretation ...
Contributions of Interdecadal Pacific Oscillation and Atlantic Multidecadal Oscillation to Global Ocean Heat Content Distribution
Publisher: American Meteorological Society
Abstract: AbstractRegional sea surface temperature (SST) mode variabilities, especially the La Niña?like Pacific Ocean temperature pattern known as the negative phase of the interdecadal Pacific oscillation (IPO) and the associated ...
Robust Adaptive Attitude Tracking Control With L2-Gain Performance and Vibration Reduction of an Orbiting Flexible Spacecraft
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents a dual-stage control system design method for flexible spacecraft attitude tracking control and active vibration suppression by an embedded smart material as sensors/actuators. ...
Contact Take-Off Characteristics of Proximity Recording Air Bearing Sliders in Magnetic Hard Disk Drives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A partial contact air bearing model and Archard’s wear law are used to investigate the air bearing and wear characteristics of proximity recording sliders during a take-off process. The air ...
Ramp-Load Dynamics of Proximity Recording Air Bearing Sliders in Magnetic Hard Disk Drive
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The revival of dynamic load/unload (L/UL) technology forces us to rethink the air bearing design philosophy, which has traditionally been established for contact start/stop applications. Reliably ...
Design and Analysis of Slider’s Landing Pads for Fast Take-Off Performance in Magnetic Hard Disk Drives
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Exponential growth in both capacity and performance has been exhausting a lot of existing technologies in magnetic hard disk drive industry, one of them being laser zone texturing. Maintaining ...
Wear Characteristics of Padded Air Bearing Sliders During a Contact Take-Off Process
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The pressing and challenging demand for resolving the stiction/glide-height conflict, driven by today’s ever decreasing head/disk spacing, forces us to constantly search for new technologies. One ...
A Cumulus Parameterization Based on a Cloud Model of Intermittently Rising Thermals
Publisher: American Meteorological Society
Abstract: The author presents a cumulus parameterization that uses a cloud model that describes atmospheric convection as consisting of a sequence of intermittently rising thermals. The total mass of thermals in a convection event ...
On the Sensitivity of Thermocline Depth and Meridional Heat Transport to Vertical Diffusivity in OGCMS
Publisher: American Meteorological Society
Abstract: Aimed at a further understanding of the role of vertical diffusivity in determining the vertical structure of the thermocline circulation and meridional heat transport in ocean general circulation models (OGCMS), sensitivity ...
