an investigation into translation of cultural concepts by beginner and advance student using think – aloud protocols
this research aims at answering the questions about translation problems and strategies applied by translators when translating cultural concepts. in order to address this issue, qualitative and quantitative study were conducted on two groups of subjects at imam reza international university of mashhad. these two groups were assigned as beginner and advanced translation students (10 students). ...
Distributed attitude synchronization control for a group of flexible spacecraft using only attitude measurements
This paper considers the problem of attitude synchronization control of a group of flexible spacecraft under an undirected communication graph and in the absence of measurements of both modal variables and spacecraft angular velocities. To solve this problem, a nonlinear observer is introduced to estimate the unmeasurable modal variables and spacecraft angular velocities. Then, the backstepping...
متن کاملModeling and Control - Flexible Structure Spacecraft
Installation dynamics, optimal thruster propulsion, and specific impulse thrust for reignitable fuel motors to regulate pointing error is obtained for geosynchronous (e.g., the Indian National Satellite, INSAT–1B), and sunsynchronous (e.g., the Indian Earth Resource Satellite, IRS–1) satellites parked in transfer orbits. Filter dynamics for slow and fast terrestrial system are obtained. Design ...
متن کاملTurner and Hall Adaptive Spacecraft Attitude Control ADAPTIVE SPACECRAFT ATTITUDE CONTROL USING NEURAL NETWORKS
Neural networks offer a unique approach to controlling a dynamically changing system. By updating synaptic weights of an interconnected, algebraic framework, desired system objectives can be reached despite an unknown operating environment. This research implements a neural network for controlling the attitude of a satellite with unknown system disturbances. The training and updating of the con...
متن کاملAttitude Estimation for a Flexible Spacecraft in an Unstable Spin
An attitude reconstruction algorithm has been developed for a flexible sounding rocket whose spin vector nutates unstably about its minor inertia axis. This algorithm deduces attitude for use in post-flight analysis of the sounding rocket's science data. An additional motive for pursuing this work has been to show that a flexible-body dynamic model can be used in a Kalman filter/smoother-type a...
