Communication for research

Hi dear friends,
I am back to Switzerland, to my school EPFL. It was two wonderful secondment months in Berlin.

Just after coming back, I had the opportunity to participate in the communication-for-research course to learn how to communicate with people in order to share knowledge. Using words on papers, drawings, posters, talks or videos, how can we reach our interlocutors? improve our language?
the teachers give us pieces of advice. I will share with you the best off  and the video that I make to practice their advice.
1. Practice your presentation until it becomes natural
2. Use body language to reflect what you are telling
3. Use colors but respect contrast and blinded color people (red is seen like green)
4. Make your friends correcting your writings before sending to your supervisor
5. Discuss ideas with friends (from discussion we develop knowledge).
6. Posters, blogs, drawing and videos are the best simple ways to share scientific knowledge

Working in Berlin

Hello dear friends, hope you are doing well. I want to tell you about my traveling to Berlin: 2 months of work and fun 😁.

Visiting Berlin museums with other ESRs working in Berlin
In the museum of science, we found  smart sewing machine, so we printed the logo of our project INFRASTAR discovering this interesting machine 😏

Horstwalde beam test
Having a hard working day in Horstwalde to try different non destructive technique for beam monitoring. 

The testing beam

Ultrasonic - Coda wave Test
Sending and receiving Ultrasonic signal in embedded sensors to check any changes inside the concrete during the loading test.  

Ultrasonic Signal

Digital image correlation
 Check the progression of cracks during loading by measuring the changes in images

 gives exact position of selected points before, during and after loading test

Fiber optics
 give the strain and the frequency of vibration during loading test

 measure the proper acceleration of the beam during the loading test

LVDT sensors
measure the linear displacement and gives the flexion of the beam during the loading test

Bridges-Visit in Switzerland

Already six months after the beginning of my PhD. I am working actually in the Laboratory of Maintenance and Safety of Structures MCS in l’EPFL with INFRATAR, the European Marie Curie Project (you can check my first post for more information).
I am working on the safety of bridges to find how we can monitor existing bridges for fatigue problem detection. My work is hard, but it is also funny and cool (I am not staying all the time in front of my computer; we have to visit bridges frequently).
I am switching between the simulation word and the real world of bridges. Oftentimes I spend hours in front of my computer analysing the data from monitoring, and sometimes I need to visit our lovely bridges to check if the data acquisition system is going well.
Let us take a look of different bridges that I discovered once during one of our bridge-visit.
The bridges are situated in Switzerland between Lausanne and Bern.

The first picture is about preparing the deck to receive a thin layer of Ultra-High Performance Fibre Reinforced Concrete (UHPFRC) for strengthening.       

 Figure 1 Strengthen the bridge deck with a thin layer of UHPFRC

Figure 2 Layer of UHPFRC

                                                         Figure 3 Smooth design of RC bridge

Visiting the railway bridge to check the monitoring system and to get the load records.
Using strain gages (picture in your right) allows good understanding of the structural behaviour of the bridge. Can you imagine that this small gage, once installed in specific positions, can give us an idea about how this huge structure is working? 

                                                        Figure 4 Railway steel bridge  

This bridge is made just with concrete, without any reinforcement. It is amazing. I am wondering about the magic recipe for such a beautiful and good concrete.  Besides, it is a very nice design.

My last picture is a panoramic view of Chillon Bridge, in Morge.

                                                                 Figure 6 Chillon bridge

We went inside the bridge girder to get the recoded data from our monitoring system.

About my PhD 😊

Hi everyone,
First, I want to present you my blog 😊.
In the context of my PhD work, my program Infrastar, Marie Curie actions, assists us to write frequently a friendly journal about our work or PhD life for our personal development. Oooh yes! With Marie Curie Project, the PhD is not just a lot of articles simulations and experiments, there is more…
What? Mmmm

Traveling around the world with training weeks and obligatory secondments (Berlin (Germany), Lausanne (Switzerland), Paris (France), Krakow (Poland), Alborg (Denmark), I don’t remember the others πŸ˜‹. The program enables us also to work with people from different countries and to collaborate and share knowledge, culture and experiences. I do not want to give you just good points about this program but the salaries are also high than normal PhDs πŸ˜. 

I have discovered Marie Curie program by luck in ABG (http://www.intelliagence.fr/ ). I wanted to work in civil engineering research; I have searched many different topics until I found this program. The conditions to apply were difficult (hhhh at least for me πŸ˜‘), it is not just about your resume and cover letter but you should present all your degrees and write at least four pages to explain the topic in which you are interested (12 topics in different countries). To be honest, I was a bit afraid when I saw that I should explain the topic and that the project is EuropeanπŸ’­πŸ’­. I was thinking that even if I write very good introduction and present all the documents, they would not choose me, since I am not European.  However, in the next days I could not stop thinking about the global experience I can have with such kind of PhD ❤ . 
EPFL, Rolex Center, Lausanne Switzerland

Therefore, I start looking for the conditions of preselection: In brief, you should have a master degree or equivalent and choose a topic in a country where you stayed less than one year (funny condition). Besides, the supervisors should not give the position to their students or family (good…).
This transparency motivated me to apply 😊.  
I put all my effort to understand the topic and to write a good presentation. And since I was too motivated to participate in the project, I was too insistent: I write many emails πŸ‘€ to ask about the progress of preselection until I was accepted πŸ˜Œ (I can share all the details with you if you are interested by such a program πŸ˜‰ )
So, I have started my PhD on the first February 2017 in l’EPFL Lausanne.

I am participating now in a European project called Infrastar (http://infrastar.eu/ ) including 12 participants from 10 different countries (Morocco meπŸ˜‹, Italy, China, Iran, India, Philippines, Lebanon, Russia, Poland and Bangladesh).
The idea behind this program is to develop an international network, to made collaborations between industries and universities, to share free knowledge and to assist PhD students to improve their personal and soft skills.
Dear friends, if you are searching for a Marie Curie PhD whatever the field, you can find the proposition hereπŸ‘‰πŸ‘‰: http://ec.europa.eu/research/mariecurieactions/
Moreover, if you are already doing your PhD, make some time for your self-development, try to convince your supervisor to publish free articles for a free knowledge and do not forget to travel a lot during conferences πŸ˜ƒ .
Wish you good luck πŸ‘.
