SUMMER INTERNSHIP REPORT FINITE ELEMENT TRANSIENT THERMAL ANALYSIS OF LASER WELDING PROCESS ABSTRACT In this project‚ Laser welding process has successfully been used for joining of two stainless steel plates. The sizes of the metal plates are 50mmX40mmX2mm each. The distribution of the temperature field in laser welding using stainless steel sheets were simulated by ANSYS. The thermal properties which have been used for thermal simulation are assumed to be varying with temperature

Our population is continuously growing‚ with newborn children being greeted into the world every day. Unfortunately‚ these greetings are short lived as micro bacteria and viruses plague every surrounding corner‚ with the potential to infect every newborn in its path with life-threatening illnesses. Vaccines are used to combat these unnecessary micro-organisms by using immunization chemicals to adjust the newborn’s immune system. The first vaccine originated in 1797 for the smallpox virus that stole

blocks. The pulse generator at a particular frequency generates the clock pulses. The clock pulses are counted by a counter and gives output after every 10 pulses. The counter drives the transistors‚ which form the triac firing circuit. The transistors fire the triacs and they provide sufficient current to the load. Decorative bulbs are connected as load for each triac. The bulbs are sequentially turned ON and OFF in forward and reverse way. [pic] The IC 555 works as the pulse generator and

When the body exercises‚ the heart rate goes up and when the body is inactive or not being active the heart rate goes down. When the pulse is pumping fast‚ then that means work is being done. Having a high heart rate is good for the heart and the body. Obese people can use heart rate and exercise to change their life.

The Physics of an MRI Machine There are many physical concepts used in a Magnetic Resonance Imaging‚ also known as MRI‚ machine. There are many physical concepts used when an MRI is taken of the body‚ such as; radio waves‚ resonance and pulse sequences‚ magnetic fields being produced and lastly‚ magnets. Radio waves much stronger than the magnetic field of the Earth are sent through the body which causes the nuclei in the body to move to a different position. When the nuclei move back
