thanks for your comment,
Deletei am deadly sure for my answer. but you can't connect 58 lamps with 19 extension boards, you required 20 extension boards. So check your answer again & then post your answer.
Dear Joginder Kumar,
Deleteans D is right
18*3 = 54 (out of four, one socket is used to connect ext.board)
1*4 = 4
total 58 lamps can be connected to 19 ext. boards
29*2 4 SOCKET means 2,2 there by 29*2=58 lamps we can connect i think

check out here, it is the problm of constraint satisfication, but can be efficiently solved using depth first method to solve so ans is ....
Q.72 ANS(A)
Answer to Q71 is C. (Other search techniques are not as optimal since the solution for this problem can be uniquely determined using constraints.)
DeleteIt's said "By viewing a problem as one of constraint satisfaction,
we can reduce substantially the amount of search that is
required as compared with a straightforward search
procedure."

hi dinesh as per all websites it is answered, but it is not sure, for Audit trail it is giving wrong ans, x1+x2+x3 prob wrong most is alike another sites..
DeleteHi Dinesh not sure, but here it is stated as
DeleteBy viewing a problem as one of constraint satisfaction,
we can reduce substantially the amount of search that is
required as compared with a straightforward search
procedure
amount of search is reduced by search method only, the optimum soln will get only by search methods.
Q44, we cannot say default is call by value only, here in cobol it is default pass by reference and also in some mid level languages it is pass by reference...
ReplyDeletewhat is the ans is undetermined.
BY REFERENCE is the default passing mechanism, and so is sometimes omitted.

Q.48 it is not constructor i think, constructor will have function and class name same.. but here the question is
ReplyDeleteFunctions defined with class name are called as
Function with class name....
Every class will have with function name so it is static, void like that i think it is asking...
Q.23, 1 is given in one input 00 confusing any ans.
ReplyDeleteHi swam,
DeleteI have given some solutions in
http://ugcnetdec2012.blogspot.com
Plz verify & give me feedback.
9.OR is solved using single layer, with OR, XOR can be solved using Self Organizing maps?....
ReplyDeleteq.48 see
ReplyDeleteA static method is called by prefixing it with a class name, eg, Math.max(i,j); . Curiously, it can also be qualified with an object, which will be ignored, but the class ...
here Max() is the function class name Math so function with class name is called the method of callins as Static method.
read the question carefully... they are using the word defined not called...it should be constructor
Deleteplz give the answer of paper 3 for these Questions 11,12,13,18,19,20,22,25,26,27,28,33,43,54,56,58,50,49,46,67,71,74,75
ReplyDeleteThanks
hi rekha i think all are not confirmed except for 73 as per google search i found c, but all given D...not sure for 8/10 ans...
DeleteFor Q.32, it is not resrouces , it is time.
ReplyDeletepls refer here clearly stated...
http://www.computersciencelab.com/MultithreadingTut1.htm
A waitable timer notifies one or more waiting threads that a specified time has arrived.
Here Waitable shows timer, also waiting threads need time to arrive/flow.(Waiting threads that a specified time it is needed....
Light weight, Heavy weight is called resources , weight in light/heavy shows only time that is under execution of the resources
DeletePls explain for Q.23, even it is like D/T flipflop, the input before T is 1, D & T work for 0 is 00 is input, but after 4 clock times 10 will get change so ans would be 10.
ReplyDeletehttp://www.ceng.metu.edu.tr/courses/ceng232/2009/lecturenotes/ceng232w7.ppt
see page no.24
clearly shows T 1 means 10 will be for Qo,Q1.
DeleteHow it works means If T is 1, in first clock cycle Q will have 0 and Q' will have 1, again in 2nd cycle Q=0,Q'=1 and T=1 means o/p again 0,1 and in 3,4th again 0,1 so Q'=1, Q=0 after 4 cycles.
DeleteFor fourier it is B (2m,2n)
ReplyDeletew[i]:= 0.0 else w[i]:=1.0/(2*n+1)
for n+1 transforms.
