In reply to Some ideas for a possible new journal

I agree that getting the community together to support your idea and send in papers is not easy. However, exact mechanism is important, because the mechanism dedicates the software infrastructure.  Epi-journal is an easy mechanism, but it is only slight improve over OA journal because most expenses of OA journals do not come from electronic hosting these papers. 

I am worried you want to make too many innovations in one go....

In reply to Some ideas for a possible new journal

But maybe I am wrong.

Start finding the editorial board.  The exact mechanism is not so important.  The huge effort is to convince people to send papers there.

In Italy we are now crazy about having citations in scopus, measuring h-index in scopus, and so on.  Starting a journal from scratch, how do you think to build your reputation, just because of the technological innovations?   In the short term, you need to have impact factor, DOI, and scopus links and indexing.

Give this point the highest priority and THEN all other aspects.   Have major players support your ideas.  Start by convincing some big conference organizers.

Why not for example launching this idea in the BOLOGNA Euromech conference?  Zhigang Suo is a big invited lecturer there, and all the other organizers, I know them well.  The conference is huge, and I could try to investigate.  In fact, I already asked Davide Bigoni about some similar ideas, and even Zhigang if I remember well, but both declined as they are too busy.

So be prepared that you need to do all your homework!    http://www.euromech.org/conferences/ESMC/ESMC10

In reply to Tragic train accident in Milano for a broken rail: 3 killed and 46 injured

Nice debate! It has been a very long topic here in Germany, e.g. in the context of the new track from Munich to Berlin, or also re the new Stuttgart main station. A few links attached.

 

People from the railway industry say: the future are the local trains:

Stuttgart’s new station:

The new track from M to B:

And you may find lots and lots about the topic… At present it is not that hot, since there is enough money floating around for investments, so both local tracks and main lines are expanded.

 

Cheers, Norbert

Epi-journal tries to reduce

Wed, 2018-01-31 14:26

In reply to Some ideas for a possible new journal

Epi-journal tries to reduce the APC cost charged to the authors by normal OA journals by leveraging arXiv. However, I think the major benefit for arXiv is instant copyright protection, idea sharing, community feedback before going through peer review. Making it localized in a journal make these benfits more relevant.  I don't think that there are much expenses to host a local arXiv. I am currently running a free platform (cdmHUB.org) for anybody to upload any information (including papers, data, computer codes), run simulation, and even request a linux workstation. And also a better metric can be constructed for the paper than impact factor and citations using the big-data associated with the paper. Publishing reviews and responses makes the story more complete. 

debates about high speed trains are high on political agendas

In China, see http://www.chinadaily.com.cn/opinion/2010-04/19/content_9745174_2.htm

See in general this link here.   There are many pros and cons and debate is high on political agendas.  If in Italy we talk of 35 billion euros, this is an amount of money which makes a difference in any country.

If people here are interested, we could debate.

..it remains difficult to raise a new journal, either traditional or innovative.  The growth of traditional journals perhaps hasn't stopped yet, and of course first or later we will move to new forms, as the previous system is on the verge of collapse.   But it is difficult to predict.   You need to put serious effort into this, and maybe the reward will be great.   I am involved in many battles in italian academia, in science, and if I find energy, I will help you too.  But it is not simple!

Try to contact my friend Vladislav YASTREBOV <vladislav.yastrebov@mines-paristech.fr>

and join a very similar French discussion-group about creating an open-access journal in mechanics:

https://www.loomio.org/invitations/aa0a97be9a80ba509623

 

This discussion was initiated by Mathias Legrand and Vincent Acary on the Mecamat mailing list, now it moved to a dedicated web-page (the link above).

 

If you could be interested by such an initiative, please join them.

Wed, 2018-01-31 13:27

In reply to Some ideas for a possible new journal

I believe it will elimiate the concern of making rejection public if the Journal arXiv is set up so that the author can decide when to send paper for peer review and they have the option to submit to other journals. In other words, those e-prints are not automatically send for peer reviews. It is debatable whether making rejection public is bad or good. However, many reputable journals are also asking the author to provide the submission history of this paper.

I see your point, but running

In reply to Some ideas for a possible new journal

I see your point, but running something like arXiv has a cost (at least, in the way that arXiv works now). That is why I thought it will be easier to piggyback on arXiv. Of course, as you mention, there are some disadvantages (if the repository is "local" it will attract more attention) but also some advantages (with a local repository, you are somehow making rejections public). In any case, it is a very good idea and it may be more appropriate using a local repository as arXiv is not fully established yet in our community.

In reply to Corriere della Sera: recruitment in Italian Academia

After we took distance from a movement which has declared national strikes last year, and got some success with 10 000 academics who did not make exams last year to ask for their salary increase.

However, the government gave a 80 million euros/year increase, but only for the young faculty, and this has made the people who initiated the movement, Prof. Carlo Ferraro from Politecnico di TORINO, still unhappy.

Ferraro has declared a new strike for June, but in a letter to him, we asked for a complete REVISITATION of his priorities, putting students, assistant professors and associate professor recruitment in TOP priority, and not the salary increase of less young Full Professor.

After circulating the letter to Ferraro, the petition has jumped today only from 1300 signatures, to 6600 in few hours!  And this is not the end.

Newspapers start to talk about us, see here.

In reply to An experiment on double blind reviews

Biswajit, based on prior work, at least in my field, I can guess up to a very high accuracy who the authors are. Thus, it is really not double blind reviews. In another post http://imechanica.org/node/22093, I made some suggestions to hold reviewers more accountable using a community-based approach. Please let me know your comments for those ideas.

In reply to Some ideas for a possible new journal

I know more and more mechanicians are using arXiv, but not many people are paying serious attention. I don't want to piggyback on arXiv, I want the journal has its own arXiv (the papers listed there can be submitted to other journals). It is kind of early view of papers before accepted. Note, in the past, we don't have early view of accepted paper and we have to wait for the hard copy and the complete issue. It definitely speeds up knowledge sharing. 

Metrics will come with strong community. EML is an excellent example for how a journal can quickly establish its reputation. 

Interesting discussion, thank

In reply to Some ideas for a possible new journal

Interesting discussion, thank you Wenbin (and Mike) for bringing this up. 

My feeling is that more and more mechanicians upload their papers to arXiv before submitting to a journal but we are still far from other fields. 

Examples of journals that piggyback on arXiv can be found in mathematics or astrophysics (see http://www.nature.com/news/open-journals-that-piggyback-on-arxiv-gather-...). Here at Cambridge, we have the journal Discrete Analysis that relies on that type of system.  

These initiatives are fantastic but with funding agencies relying heavily on metrics (namely, impact factor) it is difficult for new journals to flourish. They need continuous support from strong academics in the field (like in the case of Extreme Mechanics Letters). In any case, I do not want to sound pessimistic - the opportunity is there and I will be happy to support it as much as possible.

«Those joints among the main causes of derailments»

Professor Ciavarella (Polytechnic of Bari) opens the debate: politics chooses if it is the case to bet on the High Speed or to register and secure the network

 

 

By MARISA INGROSSO

 

BARI. For Professor Michele Ciavarella, full professor of machine design of the Department of Mechanics, Management and Mathematics of the Polytechnic of Bari, the railway disaster on the outskirts of Milan should push the country, and politics, a make priority choices between High Speed and security of the rest of the network. The expert, premising that the judiciary will clarify on the dynamics, it is skeptical that the derailment it was caused by those 23 centimeters of binary jumped. «In a situation of rectilinear motion there are examples of evidence made with trains, where they are put small bombs below, and do not derail, "he says. Thinking to «accidents of this type, strictly due - apparently - to defects on the tracks », Ciavarella cites the case of Rometta Messinese, in Sicily. In 2002, he ceded a joint. There were 8 dead. "Then - he says - there was a very long trail, many were released of any failure for time limits. And basically none remembers any more. Here, I would like to raise the debate on security in Italy. I would not like that this case is closed immediately. Yes, we must open the debate on High Speed (Av) vs low speed. " And he explains: "For the Av we are investing billions and welded type tracks, not with the joints of this last derailment. The first cost more to purchase but they cost less maintenance. And then the doubt arises that these figures are not or are not expenses good. A political question: how to spend the money? Replace the tracks on these lines a little neglected or focus on the Av? ».

The professor explains that "the joint is put for issues of thermal expansion, to connect two tracks that must be in place distance". The old model was used «up which was not developed in the 1950s the technology of welded joints. Those not welded - it clarifies - they have always given problems. On the contrary, it has been considered in the literature one of the main causes of derailment.

They are very critical elements if continuous maintenance is not ensured, both with diagnostic trains both with the use of ultrasound, that are those machines that were using Rfi technicians surprised in the area seized by the magistracy ".

As for the wooden plate placed under the joint, he says it's illegal, "it's outside of everyone prescription". He doubts that he who has put it has made a report, put it in writing: "There they are very serious prescriptions and operations they are all registered. But in this case it does not they could do it, because they could not put the piece. Writing it would have been a self-condemnation. If they did, they did it verbally.

But I wonder: how many problems like that there are they all the way? After the derailment, for a broken rail at Hatfield (October 17th 2000 died 4 people; ed), in England they checked the network and found themselves 2,000 problems of the same type. Now I believe that we should do serious verification work Also in Italy. And maybe from the third part, why those who have done it so far should not do it.

We can not wait for another accident similar, perhaps due to negligence, and the death of travelers ".

 

It is not clear if the Milan commuters have activated the emergency brake. Yet there is who has had time to call their loved ones. Also the professor shares that the passengers they should be trained, a bit like what happens on them planes. But this also requires funds.

here is the interview on the newpaper - only for italians!

In reply to Tragic train accident in Milano for a broken rail: 3 killed and 46 injured

 

 

Non mi piace autocelebrarmi, ma ho voluto fare un invervento sulla questione del disastro di Pioltello perchè sarebbe auspicabile, parallelamente alle indagini della Magistratura, aprire un dibattito serio tra tecnici politici e popolazione, sulla necessità di mettere in sicurezza TUTTE le reti, e non solo spendere 35 miliardi in Alta Velocità. Non è possibile che molte reti siano trattate in questa maniera, con giunti non saldati di vecchissima concezione che già dagli anni '60 hanno mostrato la loro vulnerabilità, nei disastri inglesi, cui si aggiunge una incredibile catena di imperizia e negligenza su cui non voglio ulteriormente commentare. Infine, in puglia avendo un'eccellenza nella produzione dei Treni Diagnostici, MERMEC, sarebbe anche auspicabile che dialogassero maggiormente con l'eccellenza del Dipartimento di Meccanica del Politecnico per fare questa seria indagine su tutta la Rete Italiana e sulle procedure di manutenzione.

Anyway, I gave an interview to a newspaper today, but it will be in italian, so I would need to google translate it.

But nothing specific of course, there is a big trial now, but a serious investigation. The journalists wanted to have a "scoop", whereas I was more inclined to complain about the present maintanance strategy, the present investments in high speed trains (35 billions) whereas we need more safety on poor mid speed trains, and other things.

LCEs in 3D

In reply to Journal club for January 2018: Recent advances in liquid crystal elastomer

Hi Shengqiang, thanks for a great review! I’d like to add that LCE architectures have traditionally been limited due to processing constraints, which generally limits LCEs to 2D or unidirectional architectures. We recently were able to align the director to arbitrary printpaths through extrusion. With this 3D printing method, we can now fabricate interesting architectures with programmed properties in 3D. This method of director alignment has virtually no limitation in dimension and will allow previously unattainable LCE architectures! Paper can be found here.

 

Best,

Arda

UMAT or VUMAT for Orthotropic Material behaviour

Mon, 2018-01-29 12:55

In reply to good point

Dear Mr. Gao,

I am looking for a UMAT or VUMAT to model Orthotropic Material behaviour. There is by default the Hill's criterion via Abaqus CAE for anisotropic material modeling, but I want to develop something further for my final model.

In this case, I am trying to find a V/UMAT for Hill criterion.

I would be thankful if you might share your experiences with me.

Best regards,
