Re: [Wien] consistency in Ueff values

2015-09-18 Thread Laurence Marks
Is it appropriate to consider how fast people walk in, for instance, Moscow
and Beirut and based upon this decide who is healthier?

As a PhD student should you really be asking this type of question on a
list? The answer is quite obvious!

dear samant
I guess in such cases a case history of your system in consideration is
going to be immensely useful before arriving at any reasonable conclusion
from the calculated and compared results of Ueff.
