RAPID PROTOTYPING TECHNOLOGIES‚ APPLICATIONS AND PART DEPOSITION PLANNING Pulak M. Pandey Department of Mechanical Engineering Indian Institute of Technology Delhi Email: pmpandey@mech.iitd.ac.in 1. INTRODUCTION Prototyping or model making is one of the important steps to finalize a product design. It helps in conceptualization of a design. Before the start of full production a prototype is usually fabricated and tested. Manual prototyping by a skilled craftsman has been an ageold practice

On December 1‚ 1969‚ the U.S. Selective Service System held a lottery to determine the order in which men who were born between 1944 and 1950 would be drafted into military service. Each day in a leap year was assigned a number from 1 to 366‚ the numbers were written on pieces of paper which were placed in plastic capsules‚ and the capsules were drawn from a glass jar. Every man who had the birth date assigned to the

the past few years there have been many abortions. The mother or the mother-in-law convince or sometimes force the women to get an abortion. “In 2005 alone there were more than 1.1million excess birth of boys-and this despite the fact that sex selective abortions are illegal in China.” In china there are more boys conceived than girls. There are more boys than girls‚ 150 boys and 121 girls. Because there are more boys than girls the parents save up their

ABSTRACT Our method operates on a graph where vertices correspond to frequent items and edges correspond to frequent item sets of size two. This distribution entails an amount of data replication‚ which may be reduced by setting appropriate weights to vertices. The data distribution scheme is used in the design of two new parallel frequent item set mining algorithms. Both algorithms replicate the items that correspond to the separator. Utility based data mining is a new research area interested

China should end compulsory military training for students of all ages. Do you remember the tough time in last year September. That we wearing the battle fatigues‚ standing under the heavy sun everyday half a month. We called it military training and the globe called ours military training as “toothbrush training”. Because everyone is taught to make the bed in the same way. Everyone is taught to place the toothbrush at the correct angle on a sink. I don’t know how boys feel‚ but in a girl’s eye

absorb only a certain amount of information at once therefore consumers brains use a screen-out process called ‘selective attention’. This is the process by which consumers screen out some ideas‚ information‚ and messages‚ but take in or retain others‚ which they then interpret according to their personal experience‚ self-concept‚ attitudes‚ beliefs‚ and other factors.[2] In early selective theories‚ Donald Broadbent (1958) proposed a ‘bottleneck’ concept where it was thought we can only process
