How the following cubic spline function is derived?
In most of the research papers on meshless methods the following cubic spline function is used as weighting function.
w(y) = 0 if y < -2,
w(y) =1/6(y+2)^3 , if -2 < y < -1
w(y) = 2/3 – y^2(1 + y/2) , if -1 < y < 0
w(y)= 2/3 -y^2(1 - y/2) , if 0 < y < 1
w(y) = -1/6 (y – 2 )^3 , if 1 < y < 2
w(y) = 0 if y >2
RMS Wave front
Hi all,
I just want to know how do we calculate the RMS wave front in frontal solver...
Thank you,

Introduction to Systems Biology
How does the cell know when to produce a protein? Why does it produce this protein? How does it produce this protein so accurately, in transcription, timing, and concentration? It is amazing that the cell functions as precisely as it needs to in response to various stimuli. What is more amazing is that the cell's actions are a result of stochastic processes.
Graduate students and publishing
I just stumbled on this very interesting discussion on why science graduate students should publish, regardless of their later career intentions. I agree with the author on most points, but believe it really comes down to two things: (1) if you aren't going to communicate your results (both good and bad!) then you might as well have not bothered to do the work, and (2) becoming a good writer is a skill that every technical person will need in any career.
How to interpret IGES files?
Hi,
Can anyone please tell me how to interpret IGES files? I mean how to extract the details of order of spline, knot vectors, control points etc form the IGES files.
Thanks

Question: Is the local energy dictating dislocation emission constant for single crystal?
Hi everyone, in my size dependence study, I find the local energy dictating dislocation emission is almost constant for varied sized samples, in given directions of single crystal. I don't know this is an interesing finding, or just a common sense. Will you give me some suggestion, Thank you!
