Recent literature emphasizes the role that testosterone, as well as markers indicating early exposure to T and its organizing effect on the brain (such as the ratio of second to fourth finger, [Formula: see text]), have on performance in financial markets. These results may suggest that the main effect of T, either circulating or in fetal exposure, on economic behavior occurs through the increa...

This paper investigates the design of spacecraft attitude stabilization controllers that are robust against actuator faults and external disturbances. A nominal controller is developed initially, using the adaptive backstepping technique, to stabilize asymptotically the spacecraft attitude when the actuators are fault-free. Additive faults and the partial loss of actuator effectiveness are cons...

An attitude recognizer of a speaker which uses prosodic features of speech is proposed and it is successfully applied to the dialogue system aiming at agreement formation. We use not only linguistic information but also some sorts of additional information supporting linguistic information in our human communication. In agreement formation dialogues, we are often required to express our attitud...

This paper addresses the problem of deriving attitude estimation and trajectory tracking strategies for unmanned aerial vehicles (UAVs) using exclusively on-board sensors. The perception of the vehicle position and attitude relative to a structure is achieved by robustly comparing a known pier geometry or map with the data provided by a LiDAR sensor, solving an optimization problem and also rob...

This article presents a robust and almost global feedback attitude tracking control scheme in conjunction with a robust deterministic estimator that constructs state estimates for feedback. These control and the estimation schemes use the natural and globally unique representation of rigid body attitude provided by rotation matrices. Attitude and angular velocity state estimates are constructed...

OBJECTIVE The question-behaviour effect (QBE) refers to the finding that measuring behavioural intentions increases performance of the relevant behaviour. This effect has been used to change health behaviours. The present research asks why the QBE occurs and evaluates one possible mediator-attitude accessibility. DESIGN University staff and students (N = 151) were randomly assigned to an inte...

Tripulse is a novel orientation/attitude estimation system that is designed to accurately estimate the orientation of a satellite borne phased array relative to one or more earth stations. This system has an accuracy potential that is signi cantly better than conventional Earth-Moon-Sun attitude sensors. Tripulse has conceptual similarities to amplitude comparison monopulse systems used in trac...

This paper present the design of a novel embedded control system for improving attitude stabilization of a quad-rotor mini UAV. The control strategy uses low cost components and includes an extra control loop based on motor armature current feedback. This additional control loop significantly improves the performance of the quad-rotor attitude stability. This technique results in a controller t...

This paper examines feasibility and performance issues in using Control Moment Gyroscopes (CMGs) to control the attitude of a fixed-wing aircraft. The paper describes a control system structure that permits allocating control authority and bandwidth between a CMG system and conventional aerodynamic control surfaces to stabilize a vehicle with neutral aerodynamic stability. A simulation study ex...
