Hello dear friends, I 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  a smart sewing machine, we printed the logo of our project INFRASTAR by discovering how this 3D printer works 😏.

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

The tested 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 pictures.

Stereo-photogrammetry 
 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.

Accelerometers
Measure the proper acceleration of the beam during the loading test.

LVDT sensors
Measure the linear displacement and give the flexion of the beam during the loading test.

A Horror story in Krakow

Travel shapes youth, as the saying goes. My travel last six weeks to Poland was full of challenges and instabilities, that broadens my analytical and critical mind. I visited Krakow, the first touristic city in Poland for professional reasons, the last obligatory secondment in my PhD, and my last destination before the end of the INFRASTAR project. Unlike my personal trips, I prepare well my professional travels, by programming and booking the flights long before and by finding a sure accommodation during my stay. I didn’t expect that it would be difficult to find a room or an apartment in Krakow during August and September. I contacted the agencies that were recommanded to me by some colleagues.

Three years already after the beginning of my Ph.D.  In other countries, I should be finishing and defending my work, but in Switzerland, things are different. Here the quality of research is much more appreciated. Therefore, a normal Ph.D. takes over 4 years.  This month we had the last meeting of our MCSA (Marie Skłodowska-Curie actions) project INFRASTAR. So we all met in Brussels to celebrate our work and give feedback about our project.  last beer with the INFRASTAR team Many conclusions were discussed, and further works were recommended. It seems that the fatigue of concrete does not have a ready to use solution, we had, therefore, the opportunity to take advantage of the synergies created by different opinions and visions. But we all agreed on one thing: Only sleep cures fatigue. And we left with this beautiful souvenir: Only sleep cures fatigue ;) Now that our MSCA project comes to an end, I would like to share with you how this project makes me a d
