RISNumerical Study of a Six-Bladed Savonius Wind Turbine
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The aim of the present paper is to investigate ways of improving the efficiency of a six-bladed Savonius rotor. The efficiency of Savonius machines is low because of the “negative drag” exerted ...
Trends in Wind Speed at Wind Turbine Height of 80 m over the Contiguous United States Using the North American Regional Reanalysis (NARR)
Publisher: American Meteorological Society
Abstract: he trends in wind speed at a typical wind turbine hub height (80 m) are analyzed using the North American Regional Reanalysis (NARR) dataset for 1979?2009. A method, assuming the wind profile in the lower boundary layer ...
Spatiotemporal Network-Based Model for Dynamic Risk Analysis on Struck-by-Equipment Hazard
Publisher: American Society of Civil Engineers
Abstract: Having an approach that can analyze and identify safety risks in the dynamic and hazardous construction environment is one of the key steps to the success of health and safety plans. Struck-by-equipment hazard is one of ...
Equivalent Linkages and Dead Center Positions of Planar Single Degree of Freedom Complex Linkages
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper proposes a simple and general approach for the identification of the dead center positions of singledegreeoffreedom (DOF) complex planar linkages. This approach is implemented through the first order equivalent ...

Publisher: American Meteorological Society
Abstract: isdrometer data measured by ground-based optical disdrometers during a midlatitude continental squall line event on 18 August 2012 in Shandong Province, eastern China, are analyzed to study characteristics of raindrop size ...
Delay-Dependent Exponential Stabilization for Linear Distributed Parameter Systems With Time-Varying Delay
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper extends the framework of Lyapunov–Krasovskii functional to address the problem of exponential stabilization for a class of linearly distributed parameter systems (DPSs) with continuous differentiable time-varying ...
Event-Based Production Control for Energy Efficiency Improvement in Sustainable Multistage Manufacturing Systems
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: There has been an increasing trend for manufacturers to shift toward sustainable manufacturing strategies in response to an ever-growing pressure from fluctuating energy price and environmental crisis. Reducing energy ...
Study on BEOL Failures in a Chip by Shear Tests of Copper Pillar Bumps
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: A chip with 40 nm technology node and beyond generally incorporates low-k/ultra-low-k (LK/ULK) dielectric materials and copper traces in the back end of line (BEOL) to improve its electrical performance. Owing to the fragile ...
Assessing the Impact of Climate Change on Environmental Outcomes in the Context of Natural Climate Variability
Publisher: American Society of Civil Engineers
Abstract: Climate change has emerged as a key threat to river ecosystems. This study presents a generic, conceptual framework for assessing the significance of climate change impact for ecological outcomes. Within the framework, ...
