The theoretical and experimental study of the behavior of the gas bubble, fixed on the surface of the solid material, under changing the acceleration of gravity
Abstract: At present time, accumulated theoretical material of the studies of the equilibrium forms of the gas bubbles, fixed on the surface of solid material in the fluid, under the decrease of the acceleration of gravity, was conducted either on the basis of the geometric laws of similitude that strongly simplified the essence of the physical processes or on the basis of the theoretical qualitative assessments of the existing hydrostatic equations …

REAL-TIME COLLISION AVOIDANCE SYSTEM USING QUADCOPTER
Abstract: Real-time collision avoidance of a quadcopter using Arduino programming and SONAR sensors is proposed in this paper. The basic idea is to change roll and pitch values with the help of Arduino and SONAR sensor. The flight controller runs on six channel PWM signals coming from receiver, four of which (throttle, yaw, arming, angle mode) are directly connected to the flight controller and the other two (pitch and roll) are …

Analytical Solution to Non-Linear Spring Mass System Free Vibration through Stepwise Linearization
Abstract: Classical method of solution of free vibration of non-linear spring mass systems has been iterative in nature as no methodology has been developed so far to obtained close form solutions. Proper time step needs to be defined upfront for obtaining realistic convergent solutions. This involves thorough understanding of the system dynamics is essential and is very challenging to the engineers at times to obtain the solution. Many a time the …

The Control by the Behavior of Gas Bubble, Fastened to the Solid Surface, Using Nonpolar Reagent and Blowing Agent Actions under Changing of the Acceleration of Gravity
Abstract: The study of separation or retention of a gas bubble, fastened to solid surface in the liquid with varying acceleration of gravity currently is relevant in connection with the solution of the problem of degassing fuel in an airplane during overloads. Solving of the problem comes to investigation of the possibility of control by the behavior of the gas bubble, fastened to the solid surface using nonpolar reagent and blowing …

A REVIEW ON WELDING OF AUSTENTITIC & FERRITIC STEELS
Abstract: Austenitic and ferritic steels are widely used where corrosion resistance is important. They are widely used in chemical and petroleum industry. There are cases where both austenitic and ferritic steels together may use like automobile radiators, automobile exhaust pipes. In such cases one need to use welding process to joint two different metals. Welding need to be carry out at very low speeds, so that proper joining of two dissimilar …
