AN APPLICATION OF THE OPTIMAL AUXILIARY FUNCTIONS TO BLASIUS PROBLEM
Journal Title: ROMANIAN JOURNAL OF TECHNICAL SCIENCES - APPLIED MECHANICS - Year 2015, Vol 60, Issue 3
Abstract
In this work, a new procedure namely the Optimal Auxiliary Functions Method (OAFM) is proposed to obtain an explicit analytical solution of the Blasius problem. Our solutions are compared with those obtained by numerical solution, revealing that our procedure is highly accurate. This proves the validity and great potential of the proposed method as a new kind of powerful analytical tool for nonlinear problems.

THE POTENTIAL OF THE 3-UPU TOPOLOGY FOR TRANSLATIONAL PARALLEL MANIPULATORS AND A PROCEDURE TO SELECT THE BEST ARCHITECTURE FOR A GIVEN TASK
The 3-UPU three degrees of freedom fully parallel manipulator, where U and P are for universal and prismatic pair respectively, is a very well known manipulator that can provide the platform with three degrees of freedom...
CALCULUS OF JOINT FORCES IN DYNAMICS OF A 3-PRR PLANAR PARALLEL ROBOT
Recursive matrix relations for the joint forces in dynamics of a planar 3-PRR parallel robot are established in this paper. Knowing the kinematics of the platform, we develop the inverse dynamic problem, using an approac...

SONOELASTIC DETERMINATION OF THE KNEE CARTILAGE ELASTICITY
Sonoelasticity and Doppler imaging are applied in this paper to detect the damage process of the knee cartilage. The cartilage is a firm, thick, slippery tissue that acts as a protective cushion between bones. It is pres...
ON THE RESONANCE WAVE INTERACTION PHENOMENON
Resonant wave interaction is a nonlinear process in which energy is transferred between different natural modes of a system by resonance. For a nonlinear system, the motion is not a summation of the linear modes, but con...
