Recovering slant and angular velocity from a linear velocity field: modeling and psychophysics
The data from two experiments, both using stimuli simulating orthographically rotating surfaces, are presented, with the primary variable of interest being whether the magnitude of the simulated gradient was from expanding vs. contracting motion. One experiment asked observers to report the apparent slant of the rotating surface, using a gauge figure. The other experiment asked observers to rep...
متن کاملIntegrating rotation from angular velocity
The integration of the rotation from a given angular velocity is often required in practice. The present paper explores how the choice of the parametrization of rotation, when employed in conjuction with different numerical time-integration schemes, effects the accuracy and the computational efficiency. Three rotation parametrizations – the rotational vector, the Argyris tangential vector and t...
متن کاملAngular velocity nonlinear observer from vector measurements
This paper proposes a technique to estimate the angular velocity of a rigid body from vector measurements. Compared to the approaches presented in the literature, it does not use attitude information nor rate gyros as inputs. Instead, vector measurements are directly filtered through a nonlinear observer estimating the angular velocity. Convergence is established using a detailed analysis of th...
متن کاملA Neural Circuit for Angular Velocity Computation
In one of the most remarkable feats of motor control in the animal world, some Diptera, such as the housefly, can accurately execute corrective flight maneuvers in tens of milliseconds. These reflexive movements are achieved by the halteres, gyroscopic force sensors, in conjunction with rapidly tunable wing steering muscles. Specifically, the mechanosensory campaniform sensilla located at the b...
متن کاملField Measurements of Velocity and Physical Parameters of Seawater and Numerical Modeling of Brine Discharge from the Desalination Plant in the Southeastern Coast of Kish Island-Iran
Abstract Temperature, salinity, water-level and current speed around brine outflow of desalination site in the Southeastern Coast of Kish Island is investigated. The dominant current is east-west tidal current with a weak residual current which affects current field partially southward. The brine discharge driven hypersaline pollution dispersion is simulated applying MIKE 21, considering thr...
