CONTRIBUTIONS TO THE STUDY OF LOWER LIMB BIOMECHANICS OF A HUMAN SUBJECT UNDO TO VIBRATION. PART I: MECHANICAL SYSTEM
Journal Title: ACTA TECHNICA NAPOCENSIS, Series: Applied Mathematics, Mechanics, and Engineering - Year 2016, Vol 59, Issue 0
Abstract
In the paper makes a study on the behavior of complex biomechanical limb under the action of vibration. The request is applied through the sole of the foot and it propagates along the leg requested through thank and the femur. The second leg is placed on a surface considered fixed, therefore the linkage of given leg and the second leg, it may be considered a cylindrical joint in plane. Mechanical System (part I) is analyzed through integration into Matlab Simulink, and it has the system of differential equations (part II), which characterizes the dynamics of it. The integrated results obtained are comparable to those existing in the literature (part III).

AN ARTIFICIAL NEURAL NETWORK APPROACH TO ESTIMATE THE VISCOSITY OF BIODIESEL-DIESEL-ETHANOL BLENDS
In order to estimate the viscosity of biodiesel-diesel fuel-bioethanol blends viscosity data of 15 ternary blends - measured between 273.15 K and 343.15 K - were used. Two artificial neural networks, with one and two neu...
CAD DESIGN OF THE ROOF FOR A NEW FARM STRUCTURE WITH DOUBLE FUNCTIONS
