One year experience of being an Early Stage Researcher (ESR)

Why i decided to become an Early Stage Researcher?I was working in an organization before becoming an ESR. I did my internship at Deutsche telekom, so i was aware of the industrial perspective of a research, and I wanted to accelerate my technical technological knowledge so that I could cope up with the theoretical and practical aspects of research. That is the reason, I applied for the ESR position, to add more knowledge content to my profile. This knowledge comes from beneficiaries and partner organizations involved in the program as well as the recruited ESRs. They are from different domains and countries. It makes the program multidisciplinary very dynamic and has good international disclosure. 
And during my first year, i had the impression that i was right. My host institution is Neostrain. And NeoStrain is a leading company in the measurement technologies for the construction industries in Poland. And i choose my host institution in an industry because it gives the perfect combi…

A architectural model that describes my Phd Goal

My task in the project is to integration of sensor and local signal procession. Now i will try to explain architectural model from system engineering approaches which will describe my Phd Goal.  Following the architectural model (AM), the AM diagram of a sensor integration is shown below. The diagram includes entity, aspects, requirements and functions of the sensor integration.


Consider a stakeholder, such as bridge contractor. They have an excessive amount of maintenance on bridges due to demands from fatigue safety and monitoring considerations. Because, bridges need to be maintained to identify of possible damage. And monitoring  is really costly because good monitoring needs ''good sensor'' which can give meaningful information. But in practise it is difficult to get meaningful information from one sensor, that is the reason sensor integration for monitoring system recognized as a significant problem. Three system elements related to the bending process are shown a…

A Successful Scientific Night

On Saturday, October 14, The Silesian University of Technology held its 12th edition of Scientific Night - The Art of Science. I participated the art of science and showed some scientific experiment. The NeoStrain families also participated in science night activities. NeoStrain came with a crack measurement scale and snow monitoring system. And we had a demonstration of body weight application by using two strain gauge sensor in the bridge and detecting the speed of the hitting to the board application using the accelerometer. The speed of the hitting on the Board application: We can detect the speed of the ball throwing on some object using basic physic of Accelerometer.  Speed or velocity comprises of two things if some objects travel at a known distance in a known amount of time this is known as velocity.

So acceleration is how much something increases has velocity over time. We have used HS-100 Accelerometer from Handsford Sensor and it was plugged into the throwing board (picture belo…

BLEIB structure at BAM

Hi Everyone!
Here i am again!!  In my last blog, I have mentioned about my secondment. So last week, I had a hard working day in Horstwalde to see the different nondestructivetechnique for BLEIB structure. And I and xin (ESR1) used the embedded ultrasonic sensor to measure the static and dynamic changes in BLEIB structure.  Here is the picture of beam:



And a picture of the static test:


And a picture of the dynamic test:
Video of the dynamic test:

Here is the embedded ultrasonic sensor measurements and signal:





Secondment and advance NDT&E training in BAM, Germany

Hi Everyone!
Here i am again!!  I have started my secondment on 1st of July in BAM, Germany. Oh yes, ''A secondment is a name given to temporary work which is assigned to a researcher in a different area from which they are already working on the project''. As i am working in a European project (Infrastar) so I have to go for secondment to work with other ESR. That is the reason i am here (BAM). And i will be here for three months. I was bit lucky when i came to BAM, because there was advance  NDT training workshop. So i had a chance to participate this workshop.  I have to say that it was an interesting experience, met lots of interesting people in BAM. Other engineers, researcher (working on NDT), which makes me happy to see such an interest in NDT testing. But mostly, the opportunity to hands on experience on sensor and measurement and discuss my work, reuniting some good comments, good contacts, that was great. Here I am attending hands on NDT testing, still, need to tra…

Who am I?

Hello! It will please some of you to know that who am I! it will please the rest of you to know that why I choose to pursue a Ph.D.?

My name is Joyraj Chakraborty, seems some Asian name! Hmm!! Yes, I am from Chittagong, Bangladesh. I completed my Master’s degree majoring in radio communication Engineering from Blekinge Institute of Technology (BTH), Sweden and undertook an internship at Deutsche Telecom in the customer equipment department. Before joining Infrastar project (10th February 2017), I worked as a scientific research engineer at KU Leuven, in Belgium from 2014 to 2015, developing an acoustic sensor localization for an unknown sound source. Drive for research is the best reason to start my Ph.D.  I have experienced a sense of excitement while working on a project of my own during working as a scientific researcher at KULEUVEN, where I enjoy the opportunity to focus on a problem of cutting-edge research. The rewards of contributing to advance knowledge in any given area can be …
