Hi all,

Do i have to use geostatic step when i using thermal expansion in soil?

Mesophase frontier

Robert G de Boer — Fri, 09 Sep 2011 17:52:58 -0400

In the states of matter, liquid and solid are often considered adjacent states, but sometimes there are mesophases between them. For instance, there are miniscule moving parts in a LCD that effect an optical switch for display purposes. Jerald Ericksen, in his Timosheko acceptance address reproduced here in iMechanica, points out that a mechanical couple, driven by an electrical field, turns the switch. Students that aspire to be more than technicians will study principles of applied physics that pertain to all states of matter.

how to remove an image

Oleksandr Glushko — Wed, 22 Jun 2011 04:25:42 -0400

is it possible to remove an image? I have accidentally uploaded a high-resolution picture...

thanks for the tags support!

I love the support you are giving on being able to add tags. I know that most image uploaders don't give you access to the title tags. This will really help other users find photos that I add when searching online, thanks!

Difficulties when adding image

Peter Cendula — Fri, 30 Jul 2010 10:16:16 -0400

I tried to add an image to my comment, so I uploaded it first with 'Add image' link in separate window and then dragged it to the original window with my comment.

The preview image appears in the comment and I set it up to be a "link to image page". However, when I preview the comment, the image is a link but points to a page like "http://imechanica.org/img_assist/properties/8626", which is the edit page of the image ;-(

The other feature which is not working - "Insert" button does not insert the image anywhere.

We should improve adding images more user-friendly, I'll be glad to help the web administrators.

Thanks

Peter

This is A SERIOUS PROBLEM!

Henry Tan — Fri, 01 Jan 2010 08:20:00 -0500

I am (and of course many others are) experiencing the same problem. For example, the following comment cannot be found by just click on the link:
http://imechanica.org/node/7162#comment-13180

The same problems will keep occurring since as iMechanica grows more and more comments are posted in just one Blog. This is a serious problem for someone who is posting on the second-page.

Regards,
Henry.

fluid and solid mechnics

mechovator — Wed, 15 Jul 2009 13:34:23 -0400

I work on both fluid and solid mechnics and most probably will be working on FSI problems in future. I am here, lets see if imechanica helps this youngster on his way through or not.

Thanks for your article. You told about maintain essays, books and websites. It is a good thing. What are all the information you maintain in your site via essays, books and websites.

popular in a social networking website, such as Facebook. Drupal has some flexibility, and will surely improve in future releases. But at this point, perhaps we can keep all such information optional. So that beginners will not be confused. We have to be patient with Drupal and lookup table in the background, so that MIT will be the same as Massachusetts Institute of Technology

Hi Alejandro,

I had the same problem. I believe it works, if you refresh the page after uploading the photo and getting the error message! Sometimes it also uploads your photo even though you have got the error message, so check; you might have the updated photo on your account. I know something is not working there, but I kept trying!

Error message while updating my profile photo

Alejandro A. Ortiz — Sat, 04 Oct 2008 19:56:38 -0400

I have tried to upload in many ways my profile photo (in IE and Mozilla) subjected to the following constraints:

Maximum dimensions 85x85

Maximum size 100 kb

And the following error always arose:

The selected file /tmp/tmp_FZcVQT could not be copied.
Failed to upload the picture image; the pictures directory doesn't exist.

Any suggestion?

Thanks,

Alejandro A. Ortiz

get fluid people involved.

Charlie.liang — Wed, 10 Sep 2008 01:15:50 -0400

One important group of people that imechanica shall attract are fluid-structure interaction researchers. I graduated with PhD training only on fluid dynamics, but later on I gained my interests on solid mechanics while working in applied mathematics department. I believe that many researchers of this group are working in departments of mechanical, civil, aerospace engineering as well as applied mathematics.

Fluid and solid equations could be solved all together in an unified approach (http://dx.doi.org/10.1016/j.jcp.2007.12.004) using the Finite-Volume method which is more popular in CFD. This convinces me more that imechanica in the future would include people from both solid and fluid sides, and even applied mathematicans.

I am recently involved with one interesting conference (http://www.fifthmitconference.org/). As a reviewer of Computers and Structures, it appears to me that more and more fluid researchers are sending good-quality manuscripts to participate this conference and publish fluid mechanics papers in this well-known solid mechanics journal. In terms of unifying the divergence between solid and fluid, the solid mechanicians are already pushing harder than the fluid side.

I happen to use TinyMCE on my petition site. I had my coder implement it into the place where users actually create their petitions. I feel like it gives them a little more creative freedom.

keeping a check on features

Zhigang Suo — Sun, 10 Aug 2008 10:01:00 -0400

I've been reading more books on topics related to the development of iMechanica, and will add them as comments to this post. Please do so when you read a good one.

Yesterday I checked out from my local library the new book Designing for the Social Web by Joshua Porter. The 188-page book is a delight to hands, eyes and mind. Many full-colored screen shots, and concise analyses. I'll let customers at Amazon give you an overview of the book.

On p. 23 of the book, Porter talked about the AOF method of design:

Focus on the promiary Activity.
Identify your social Objects.
Choose your core Feature set.

Toward the end of the chapter he advised keeping a check on features:

Each feature means more complexity.
Just say no to the urge to add too many features.
Don't copy features.

Porter related an anectote about Steve Jobs. Jobs was talking to music industry people, and said the following:

I know you have a thousand ideas for all the cool features iTunes *could* have. So do we. But we don't want a thousand features. That would be ugly. Innovation is not about a thousand features. It's about saying No to all but the most crucial features.

blogs worth millions -- how many $ is imechanica worth?

When imechanica will reach this $millions status?

Gaia Online Gets $11 Million Third Round For Teen-Oriented Virtual World

Gaia Online,
the teen-oriented virtual world and community site, has raised an $11
million third round led by Institutional Venture Partners. The company
has disclosed over $21 million previously, not including an unspecified
amount from Sony (NYSE: SNE),
bringing its total raise to over $32 million. The virtual worlds space
has seen plenty of activity lately, including some major exits, though
it’s still unclear how things will ultimately shake out. Early leader
Second Life seems to have peaked, while Google (NSDQ: GOOG)
recently dipped its toes in (how far they’ll go with it remains to be
seen). Gaia claims 350,000 unique users daily, and 5 million on a
monthly basis. The San Jose-based company has made virtual goods
transactions central to its business model. Release.
