Fortran 90 library for maximum-entropy basis functions

Submitted by N. Sukumar on

Attached is a tar archive for a Fortran 90 library to compute maximum-entropy basis functions.  I have used the G95 compiler. The manual in PDF is also attached and a html version of the same is also available, which provide details on how to install the code and its capabilities. The library is released under the GNU Lesser GPL version 3 license.

Review papers

Submitted by RoozbehSanaei on

One of the most important things every researcher does in the beginning of his introduction to a topic is review process. Most helpful papers in this regard are review papers. Review papers are important. They are primary and best way to understand the value of a work for the societyto award and grant. They help researchers to find out needs of people who use our research and goal functions of scientific society. Help researchers to find out good topics and also good solutions. And the final effect of a research on the society.

Modeling polyurethane

Submitted by Andreas Burger on

I've started to look into the modeling of polyurethane.  So far I'v found one paper that specifically looks into how to model the mechanical behavior of PU. It describes a possible constitutive model for PU:

Stress-strain behavior of thermoplastic polyurethanes, Qi,H.J.; Boyce, M.C., Mech. Mater. 2005, 37, 8, 817-839

Does someone know of any other resources on the modeling of PU?  Thanks, Andreas

Elastic deformation of substrate due to rotation of rigid pillar

Submitted by Steffen Brinckmann on

Consider a ridig pillar ontop of a elastic substrate. Applying a moment to the pillar will lead to elastic deformation of the substrate. If the pillar is infinitly large in diameter, then this problem is the same as an infinitely sharp crack, considering the symmetry of the crack problem, i.e. there are square root singularities. However, the infinitly large diameter assumtion does not hold if the global rotation of the substrate under the pillar is of interest, because the both sides of the pillar interact.

CFL number

I'm working at a University where we are developing and running interface software for CFD simmulations. There are no CFD specialists in my lab, however, so we get the information we need from a couple of other labs around campus.

Unfortunately, no one seems to know what the CFL number is, or how to use it.

Can I just get a simple explanation of the CFL number and a general range in which it should lie?

Thank you! 

quries for a battery driven car

Submitted by ashish katarkar on

 I am a doctor by profession  but reading about fuel prices and pollution got me in this

i use a electric scooter for last two years and its fine for my daily work as well as for my part to keep earth clean

i want to ask if i put a calcium calcium battery to run a 1000kg gross weight car with a800 cc petrol engine

firstly what battery power i need

secondly at asteady speed of 80kmph will the dynamo can recharge the batteries sothat the speed can be maintained
