the bender-gestalt test was given to thirty mentally-retarded psychiatric patients. the mean, standard deviation, and standard error were 56.73, 26.25, and 4.80 respectively. rotation was the most frequent major deviation which occurred in all the designs. design # 7 was the most difficult one to be reproduced in the sample. this design by itself, was subject to 47% of distortion, 79% of omissi...

A robust state feedback design subject to placement of the closed loop eigenvalues in a prescribed region of unit circle is presented. Quantitative measures of robustness and disturbance rejection are investigated. A stochastic optimization algorithm is used to effect trade-off between the free design parameters and to accomplish all the design criteria. A numerical example is given to illustra...

Elastic boundary conditions play an important role in the buckling analysis of cylinders under compressive loading. These structures are used widely aerospace applications and highly sensitive to geometrical, material, loading, imperfections. In fact, presence these imperfections can lead catastrophic failure. 1968, NASA reported relations for obtaining Knockdown Factor (KDF) based on empirical...

Multiple-subject magnetic resonance imaging (MRI) has been used in phenotyping studies to reduce the total experimental time by simultaneously capturing images of multiple animals using single or radio frequency (RF) coils. However, conventional methods must consider decoupling circuits minimize mutual inductance coupling between RF These unnecessarily increase field view (FOV) and image acquis...
