Baluncore replied to the thread A very naive encryption scheme : How would an expert crack it?.The OP cipher as described seems very messy and prone to errors. It would need to be programmed into a computer of some sort. Spyware on... -
Baluncore replied to the thread A very naive encryption scheme : How would an expert crack it?.OTPs do not work for large data volumes. The OTP fails when those responsible for generating the pads become overworked, or get lazy...

Baluncore replied to the thread A very naive encryption scheme : How would an expert crack it?.There is too much confusion, and no depth, so cracking it by cryptanalytic techniques is not really feasible. Practical cryptanalysis...

Baluncore replied to the thread Eliminating a differential of an e-rickshaw by using 2 motors..Assuming the motors are identical DC motors, wire them in series. The currents will then be the same, so the torques will be the same...
-
Baluncore replied to the thread Vector/Phasor Addition.I think the only advantage is that it avoids the one final evaluation of a square root, but accuracy there is not usually critical. The...
-
Baluncore replied to the thread Vector/Phasor Addition.It does make sense. Given a chain of added vectors, and knowing the direction of the total, all vectors making up the chain can be...
-
Baluncore replied to the thread Vector/Phasor Addition.The problem with the cosine and sine rule technique for vector arithmetic, is that there are too many opportunities to get a sign wrong...
-
Baluncore replied to the thread Vector/Phasor Addition.Inputs. V1 = 10 units at +15° from reference V2 = 70 units at +90° from reference Convert polar to rectangular. x1 = 10 * cos( 15° ) =...

Baluncore replied to the thread Vector/Phasor Addition.Yes, but tan-1(y/x) is Atan(y/x) and it gives you the slope of the line as an angle, not the direction of the vector, there is a...
-
Baluncore replied to the thread Vector/Phasor Addition.Be more specific. Which method, to do what? Summing vectors involves summing the x and y coordinates independently. That is done as if...
