TAILIEUCHUNG - FABRICATION OF PERFORATED POLYMER MEMBRANES USING IMPRINTING TECHNOLOGY

Automation is also important to replace the skilled workers. Welding is one of the most important jobs in shipyards, and the ratio of the mechanized welding in Japanese shipyards is 42% in average, and 64% in the most advanced shipyard (Miyazaki 2008). Further development of mechanized welding calls for a breakthrough. Miyazaki (2008) showed some challenges such as mechanized welding inside the double hull structure in the assembly stage, and mechanized butt welding of longitudinals inside the double hull structure in the erection stage. These can be realized through development of small-sized robots which can move through manholes, root gap. | FABRICATION OF PERFORATED POLYMER MEMBRANES USING IMPRINTING TECHNOLOGY A Thesis Submitted to Graduate Faculty of the Louisiana State University and Agricultural and Mechanical College in partial fulfillment of the requirements for the degree of Master of Science in Mechanical Engineering in The Department of Mechanical Engineering by Anish Roychowdhury National Institute of Technology NIT formerly REC Durgapur Burdwan University 2001 May 2007 To my parents family and friends ii ACKNOWLEDGEMENTS I would like to express my sincere thanks to all the people who have been instrumental in my success throughout my master s program here at Louisiana State University. It has been a pleasure to be guided motivated and supported by Dr. Sunggook Park. I would like to thank my advisor for introducing me to the field of Imprinting Lithography. Thanks are extended also to Dr. . Murphy and Dr. A. Raman for being my committee members and for their time and expertise to evaluate the thesis. I immensely thank Dr. D. E. Nikitopoulos Dr. R. Devireddy Dr. D. Cao Dr. M. Hupert Dr. Feng Xu and Jason Guy for their help and technical suggestions group members of the Microsystems Laboratory and cleanroom staff at Georgia Institute of Technology and LSU CAMD for their help. I also thank my colleague Andrew Becnel Eugene Lopez and Alum Yi for their technical assistance. It is time to mention about my friends Praveen Pahuja and Dinesh Pinisetty without whose help it would have been difficult for me to continue with my work. Finally I would like to acknowledge the love of my parents Dr. Rajkumar Roychoudhury and Nilanjana Roychowdhury and their support and encouragement throughout my school days. .
