RISA Novel Combined Particle Swarm Optimization and Genetic Algorithm MPPT Control Method for Multiple Photovoltaic Arrays at Partial Shading
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: The output characteristics of multiple photovoltaic (PV) arrays at partial shading are characterized by multiple steps and peaks. This makes that the maximum power point tracking (MPPT) of a large scale PV system becomes ...
The Comparison of Viscous Force Approximations of Smoothed Particle Hydrodynamics in Poiseuille Flow Simulation
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Poiseuille flows at two Reynolds numbers (Re) 2.5 × 10−2 and 5.0 are simulated by two different smoothed particle hydrodynamics (SPH) schemes on regular and irregular initial particles' distributions. In the first scheme, ...
Almost Periodic Solutions for a Class of Stochastic Differential Equations
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this paper, the existence and uniqueness of the squaremean almost periodic solutions to a class of the semilinear stochastic equations is studied. In particular, the condition of the uniform exponential stability of the ...
A Note on the Stability Indicator of the Atlantic Meridional Overturning Circulation
Publisher: American Meteorological Society
Abstract: his study examines the validity of the net freshwater transport ?Mov as a stability indicator of the Atlantic meridional overturning circulation (AMOC) in a low-resolution version of the NCAR Community Climate System Model, ...
A Diagnostic Indicator of the Stability of the Atlantic Meridional Overturning Circulation in CCSM3
Publisher: American Meteorological Society
Abstract: diagnostic indicator ?Mov is proposed in this paper to monitor the stability of the Atlantic meridional overturning circulation (AMOC). The ?Mov is a diagnostic for a basinwide salt-advection feedback and defined as the ...
Continuous Approximation of Deficit Functions for Fleet Size Calculation
Publisher: ASCE
Abstract: It is a fundamental and important task to determine the minimum fleet size required for a public transit (PT) system because the fleet cost is a major operating expense experienced by PT agencies. More importantly, the ...
Evaluation of the Spatial and Temporal Uncertainties Distribution of Daily-Integrated Shortwave Downward Radiation Estimated from Polar-Orbiting Satellite Observation
Publisher: American Meteorological Society
Abstract: he polar-orbiting satellite sensor, which can observe the entire Earth?s surface with good spatial and spectral resolution, is a potential tool for estimation of global downward shortwave radiation (DSR). However, it can ...
Nonuniform Stress Field Determination Based on Deformation Measurement
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In this investigation, we demonstrate a technique that, under certain circumstances, will determine stresses associated with a nonuniform deformation field without knowing the detailed constitutive behavior of the deforming ...
Investigation of the Effect of Simulated Atmospheric Conditions at Different Altitudes on the Combustion Process in a Heavy-Duty Diesel Engine Based on Zero-Dimensional Modeling
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Plateau diesel engines suffer from increased fuel consumption and deteriorating emissions. These problems were mainly caused by the combustion worsening inside the chamber. However, limited research has been done specifically ...
Machine Learning Assisted Analysis of an Ammonia Engine Performance
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Currently, the interest in utilizing ammonia in internal combustion engines stems from the trend toward decarbonization, as ammonia is a zero-carbon footprint fuel. Existing studies on ammonia engines are limited and most ...
