## Checkuser discussions

Hi Banerjee. If you can spare the time, your opinion would be greatly appreciated in the discussion currently going on about getting local Checkuser permissions here on Wikiversity. As an active user here, you're probably familiar with the "quiet, behind the scenes" way that we introduce new Custodians, but requesting Checkuser actually requires a "show of support" for the foundation stewards to give us this tool.

If you're not familiar with Checkuser, it's a tool we can use to find the source IP address (and/or alternate accounts) of vandals and others who mean harm to the project. This allows us to both "stop the problem at the source", or in some cases lets us know we can't stop something at the source if an IP is shared by one or more constructive contributors. --SB_Johnny | talk 11:01, 31 August 2007 (UTC)

## Schematic diagrams

Hi. I've been reading through a lot of stuff you have contributed here. It's great stuff—thanks for all your hard work here.

You seem to have produced a lot of high-quality structural/mechanics diagrams for use in your resources. I'm curious what tools and techniques you use to create them. Is there any change you could explain a little?

Thanks—Papna 20:47, 21 October 2007 (UTC)

Thanks for your interest. The figures were mostly drawn using XFig and then saved as EPS files for my courses. I used the ImageMagick "convert" utility to convert them into png or jpg for use in the wikis. -- Banerjee 21:14, 6 November 2007 (UTC)
Thanks for the information and again for all your hard work on Wikiversity. I installed and am playing with XFig. Hopefully I can get to a point where I can make diagrams as effective as yours. Papna 15:46, 8 November 2007 (UTC)

## Superplasticity

First of all, thank you for your great and very interesting work on FEM.

I'm interesting on superplasticity and FEM, and large deformations of superplastic plates and shells.

Can you help me? Thanks! --Accurimbono 20:47, 28 December 2007 (UTC)

Hi, I am looking at Waves in composites and metamaterials/Point sources and EM vector potentials and wondering, why there are links like "Chew95". What did you wonted to place there? Refernceces? Citation? Other content?--Juandev 08:19, 2 January 2009 (UTC)

These pages were translated automatically from my lecture notes written in LaTeX. I haven't had the time to go through all the pages to correct errors and inconsistencies that remain. I am hoping that you and others will be able to fill in the gaps when you discover them. Chew95 refers to "Waves and Fields in Inhomogeneous Media" by Weng Cho Chew [1]. Details of the references are given at the end of each lecture (in most cases). Banerjee 21:19, 4 January 2009 (UTC)

## Introduction to Elasticity/Compatibility

Banerjee,

I came over your article on Introduction to Elasticity/Compatibility, which was interesting, especially I liked the short notion for the compatibility equation: ${\displaystyle \ \nabla \times \nabla \times \epsilon =0\ }$ . However I am a bit confused about the definition of ${\displaystyle \ \times \ }$ . I thought it meant curl, but I am not sure how it works on the 2nd order elasticity tensor ${\displaystyle \epsilon }$ . It is usually just defined between 3D vectors. Could you please specify this or give me a reference? Thanks
