Oceanographic Experiment Design II: Genetic Algorithms
Publisher: American Meteorological Society
Abstract: The oceanographic experiment design problem is one of many problems in oceanography requiring nonlinear, constrained, global optimization. Having already revisited a steady-state (time-independent) experiment in acoustic ...
Interpretation of the Mariner 5 Lyman Alpha Measurements
Publisher: American Meteorological Society
Abstract: The Mariner 5 Lyman alpha measurements can be fitted with the barometric-exospheric equation only if a two-component model atmosphere is used. Of the three possible hypotheses to explain such an atmosphere, the model ...
Estimation of Gamma Raindrop Size Distribution Parameters: Statistical Fluctuations and Estimation Errors
Publisher: American Meteorological Society
Abstract: The gamma distribution is often used to characterize raindrop size distributions (DSDs). However, the estimation of measured raindrop distributions suffers from the shortcomings of statistical sampling errors, which become ...
Numerical Modeling of Sulfur and Nitrogen Chemistry in a Narrow Cold-Frontal Rainband: The Impact of Meteorological and Chemical Parameters
Publisher: American Meteorological Society
Abstract: To better understand the impact of various meteorological and chemical parameters on chemical deposition from winter storms, the chemistry and microphysics of a narrow cold-frontal rainband and its associated stratiform ...
Oceanographic Experiment Design by Simulated Annealing
Publisher: American Meteorological Society
Abstract: The oceanographic experiment design problem is discussed in the context of several simple examples drawn from acoustic tomography. The optimization of an objective function?chosen to characterize the array design? is carried ...
Additively-Manufactured Servopumps for Soft Robots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: In contrast to soft robots, typical electromechanical robotic systems are able to leverage a wide range of available brushless servomotors and compatible gear reduction devices. This makes the selection of components to ...

Abstract: In contrast to soft robots, typical electromechanical robotic systems are able to leverage a wide range of available brushless servomotors and compatible gear reduction devices. This makes the selection of components to ...
An Integrated Frameless Motor Gerotor Pump for Hydraulic Actuation of Soft Robots
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: Abstract. This work presents a novel geometry for a gerotor hydraulic pump integrated into the rotor of a brushless, direct-current, frameless motor. The design eliminates excess dynamic seals and produces a pump that is ...
An Energetic Control Methodology for Exploiting the Passive Dynamics of Pneumatically Actuated Hopping
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: This paper presents an energetically derived control methodology to specify and regulate the oscillatory motion of a pneumatic hopping robot. An ideal lossless pneumatic actuation system with an ...
Passivity-Based Impact and Force Control of a Pneumatic Actuator
Publisher: The American Society of Mechanical Engineers (ASME)
Abstract: To carry out stable and dissipative contact tasks with an arbitrary environment, it is critical for a pneumatic actuator to be passive with respect to a supply rate consisting of the spool ...
