ok sir. I get it. Thank you so much for your help, Sir.

Gomathi

congruence modulo 4

Gomathi

Aug 23, 2012 16:43

I have to check whether binary operation {0,1} is a homomorphic image of ($Z_4,+_4)$, Sir.

Gomathi

Aug 23, 2012 16:40

Can you kindly explain how to prove it by taking values as 0 and 1? should I replace them by 0 and 1?

Gomathi

Aug 23, 2012 16:38

oh...sorry sir. I read the question wrongly. It's given as homomorphic only and not isomorphic.

Gomathi

Aug 23, 2012 16:32

@MattPressland But, it has been given that, by taking g([0])=g([2])=0 and g([1])=g([3]) = 1 they have proved it as isomorphic sir.

Gomathi

Aug 23, 2012 16:29

Sir, I have another doubt. These two tables are of same size. But what if both are of different size. For eg. $+_4$ ([0],[1],[2],[3]) and B={0,1} with operation + ?

Gomathi

Aug 23, 2012 16:29

Thanks. But how to find the right combination? Is that by trial and error method?

Gomathi

Aug 23, 2012 16:29

Ok sir. I get it. Thank you so much for your help.

good night

Gomathi

Aug 23, 2012 10:48

@DanielPietrobon ok brother. Thank you so much for your help.

Gomathi

Aug 23, 2012 10:32

Can you kindly gather these together and post it as answer, so that I will accept it.

Gomathi

Aug 23, 2012 10:31

Am a girl. :)

Gomathi

Aug 23, 2012 10:29

am i right?

Gomathi

Aug 23, 2012 10:29

only based on the second step, we add the remaining elements to the initial step.

Gomathi

Aug 23, 2012 10:29

the first step is the initial set of elements

Gomathi

Aug 23, 2012 10:29

to make it clear.

Gomathi

Aug 23, 2012 10:28

yes...thank you so much

Gomathi

Aug 23, 2012 10:28

we miss 6...

Gomathi

Aug 23, 2012 10:28

3,9,27,...

Gomathi

Aug 23, 2012 10:27

we will be missing certain elements

Gomathi

Aug 23, 2012 10:26

so, is it x+y always?

Gomathi

Aug 23, 2012 10:25

Yes.Also, why is it always x+y,...? Can't it be x*y or any other relations?

Gomathi

Aug 23, 2012 10:25

after 5, 5+2 for 7

Gomathi

Aug 23, 2012 10:24

once 3 comes in there, we can form 5 using 3+2,...so we can get multiples of 5 also...am I correct?

Gomathi

Aug 23, 2012 10:24

3,6,9,...

Gomathi

Aug 23, 2012 10:23

by giving multiples of 3

Gomathi

Aug 23, 2012 10:20

In the second example, it is given as both 2 and 3 because multiples of 2 or multiples of 3 alone doesn't make the set. So, initially they have given both. Am I correct?

Gomathi

Aug 23, 2012 10:17

@DanielPietrobon So, first time we take 3, then 3+3=6, then 3+6=9, then 9+6=15, etc. Am I correct?

Gomathi

Aug 23, 2012 10:16

yes sir. Thank you.

Gomathi

Aug 23, 2012 10:16

so, 3, 6, 9 ,12, etc

Gomathi

Aug 23, 2012 10:13

@DanielPietrobon now it has 3 and 6 sir

Gomathi

Aug 23, 2012 10:06

@DanielPietrobon But, they didn't mention that y is also 3, Sir.

Gomathi

Aug 23, 2012 10:06

@DanielPietrobon So, initially as they have mentioned 3 belongs to P, we take both x and y as 3. Am I right, Sir?

Gomathi

Aug 23, 2012 10:06

@DanielPietrobon How did they found that the set has multiples of 3 in example 1 and how to write the definitions in Example 2, Sir?

@pauska Yeah. I will ask in the main site. But, don't tell that I'm also one of the people who don't do any work on their own. I just had a couple of doubts and I needed clarification. Thats all. Thanks anyways.

Gomathi

Mar 22, 2012 14:46

@MDMarra I didn't know it actually. I'm new to this. You may have guided me. I didn't mean to bring disrespect.

Gomathi

Mar 22, 2012 14:43

Is this how you treat people when they ask you for help?

Gomathi

Mar 22, 2012 14:40

Gomathi

Mar 22, 2012 14:39

I didn't ask you

Hi friends, I am currently doing a project in Matlab regarding liver segmentation. I used region growing for that. I need to compare the region growing method with any other method. Can you suggest me any segmentation method?(It must be worse than region growing)
