Facial aging is a biological phenomenon. Skin properties change with time, and gravity and facial expressions exert mechanical deformation. Knowledge of these alterations may suggest ways to reverse them by identifying the corresponding distortional forces. The aim of this study was to determine a pattern of change for parameters of the face during the(More)
The vocal cords play an important role on voice production. Air coming from the lungs is forced through the narrow space between the two vocal cords that are set in motion in a frequency that is governed by the tension of the attached muscles. The motion of the vocal cords changes the type of flow, that comes from the lungs, to pulses of air, and as the(More)
Printed Circuit Board (PCB) is the most important component of the electronic industry and thus, the electronic mass-production facilities make an attempt to achieve Printed Circuit Board with 100% quality assurance. To achieve Printed Circuit Board with 100% quality assurance i. e. to produce zero-defect Printed Circuit Board, inspection method is the(More)
—This paper presents a system for detecting angular position of warships, using features extraction techniques from acquired digital imaging and artificial neural networks. The used ships images are graphically generated by three-dimensional solid modeling software. Different groups of features are considered. They are obtained from modelled ships at(More)
