Diploma!Help!

Posted: 20 Apr 2011 09:09 AM PDT

I am doing the internship in the company providing custom manufacturing (lazer, AWJ, Plasma, Oxy cutting, bending, welding) service. Production type - single products, or small batch production.
actually the company do not name any engineering problem that is common in their activity except the need for new technology and automated stock.

But i do need to design the tool or structure that could help in any of mentioned processes - supporting/clamping equipments, loading system, transportation line from one manufacturing unit, universal structure for welding ... I have no idea!?

Please help! Any suggestions! and urgent!

I would be very grateful

The Big Question Facebook: Most Valuable Company in the World?

Meanwhile, flashback to 2006 when Mark Zuckerberg explains that he "threw together" the social network in about a week's time.

Not for me to judge. For info.

Tunnelling Methods

Posted: 20 Apr 2011 07:01 AM PDT

Since tunnel is also part of Civil, why don't we discuss about tunnels, tunneling method, etc.
It's seems that there is no discussion here about tunnels. :)
I hope you all Civil CEans will contribute here. :)

micro processors and controllers-learn and contribute

Posted: 20 Apr 2011 06:46 AM PDT

hi friends,
as we are going with learn and contribute concept here i am giving a thread for micro processors and micro controllers
lets learn them and make the subject rocking :)
here i am giving a brief idea
let us see what is micro processor?
hmmmm i think my link of micro processor had answer for it
http://www.crazyengineers.com/forum/...s-history.html
the main difference of processor and controller upto my knowledge is
processor is used for many apps and controllers are used for only specified purposes
and the components inside them are different
now i am going to ask some questions as we usually do
as it is starting i am asking basic questions hoping this thread is going to be long
1.why we are upgrading processors with the increase in bit numbers?
2.what are the main logics used in design of processors and controllers?
3.why controllers are designed only for specific purposes?
rules:1.key paper will not be released
2.each post gets 1 mark :P
3.answers will be decided only by the discussions
finally 4.feel free to ask doubts in micro processors and controller project doubt in this thread and no spam please

k lets make all the people who are weak in this subject as experts in it
lets rock CE :happy:

Hi there,

I have a little problem with java,
I can't find my mistakes if someone can help me to complete it,
I should submit my work on Monday before 16h

here is what i've done so far but doesn't want to compile:
Code:
Movie
title string
screen string
showtime string


List <Movie> moviz= new ArrayList<Movie>();

Movie m1= new Movie ("Men In Black", "Screen 10", "13h30,16h00,19h30" );
Movie m2= new Movie ("Matrixx", "Screen 11", "14h30, 16h30,18h30" );
Movie m3= new Movie ("Devdas", "Screen 12", "15h30, 18h00, 20h00" );
Movie m4= new Movie ("Source Code", "Screen 13", "13h30, 15h30, 17h00" );
Movie m5= new Movie ("Limitless", "Screen 14", "12h30, 15h00, 17h30" );

moviz.add(m1);
moviz.add(m2);
moviz.add(m3);
moviz.add(m4);
moviz.add(m5);

System.out.println(Movie); // implicity call toString method of List

public String toString()
