One of the most famous problems of classical geometry is the Apollonius' problem asks construction of a circle which is tangent to three given objects. These objects are usually taken as points, lines, and circles. This well known problem was posed by Apollonius of Perga ( about 262 - 190 B.C.) who was a Greek mathematician known as the great geometer of ancient times after Euclid and Archimede...
(a) If we consider the intersections of the circle Hi(O) (center Hi and radius HiO) with the line Ai+1Ai+2, then we obtain six points which all lie on a circle with center H (first Droz-Farny circle). (b) If we consider the intersections of the circle Mi(H) (center Mi and radius MiH) with the line AiAi+1, then we obtain six points which all lie on a circle with center O (second Droz-Farny circl...
flow in natural river bends is a complex and turbulent phenomenon which affects the scour and sedimentations and causes an irregular bed topography on the bed. for the reason, the flow hydralics and the parameters which affect the flow to be studied and understand. in this study the effect of bed and wall roughness using the software fluent discussed in a sharp 90-degree flume bend with 40.3cm ...
