My Research Tour Across Europe(Day 5) - Home at Last! - Back From Serbia to Budapest

Hey folks!
Still on my Research tour. Guess what? Today would be exceptional. I'm waking up in Serbia today, and hopefully would be spending the night in Budapest, hundreds of kilometres away. Such is the life of a researcher.
Just as you know, I would first go about breakfast.

1. Today's Breakfast
I had a simple breakfast as usual. I wish you could join me!


2. Packing for Departure
I would have done this the previous night, but I'm doing it now since I have some time.


3. At the Subotica Railway Station, Serbia
This is the same railway station I arrived. This  are some of the pictures of the train.

4. A Beautiful Train Ride
They call it railJet and it’s really a rail jet because you have the same feeling as in an air plane.
Air transportation, they say, is the safest means of transportation. But we all know that is not true. It’s the rail. This would be a discussion for a different time.



5. At the Keleti Payaudvar Railway Station in Budapest, Hungary
Disembarking from the train, it's been an interesting 3-hour train-ride from Serbia to Budapest


6. Home at Last
Would you not believe it! I'm back to my lonely home. Sure, cute little but lonely home really.



7. Preparing Welcome Dinner
After a long trip, I deserve a welcome-home treat. So I’ll take a special meal tonight. I think I have some stuff in the fridge. But for the first time in my stay in Europe, I’ll be having a bottle of wine in my fridge.




My Research Tour Across Europe(Day 3) - SISY2018 Conference Day 2 in Subotica, Serbia

This is the second day of the conference and actually 'my day'. Guess what? I'm in the program today and would talk about my paper: "Performance Analysis of the Microsoft .Net and Java-Based Implementations of REST Web Services"




The program today starts at 9:00 and I need to be there in time. But as you know,  I need to look for a breakfast and then we had a good lunch in Hotel Galleria.

This is Prof. Imre J. Rudas of the Obuda University, Budapest Hungary, receiving some souvenir.




1. At the Subotica Tech
This is where the program would take place for today and since I've not been here before, I left home a little earlier though the venue is just a few minutes walk from my hotel room


2. Highlights of Session on Intelligent Robotics
What I enjoyed most in this part is the presentation by a professor from the Obuda University. He gave about 30 minutes presentation on the theme: Modbus-OPC-UA Wrapper using Node.RED and IoT-2040 with application in the water industry.

3. Highlights of Session on Intelligent Mechatronics and Intelligent Manufacturing Systems
The question is: What is Mechatronics? Mechatronics is a multidisciplinary field of engineering which combines

4. Highlights of Session on Informatics
This is the  session I did my presentation and that is me defending my 4-month-long work. I also made some mew friends here. But there were some preceding presenters also did a very good job.

For example, the first presenter, spoke on the theme: 'Magic Dashboard: Software System for Real-Time Development Tool Tracking'. He explained that this system would be used to gather data from a variety of project management data sources. They used tools such as Go, ReThinkg, Gin and Viper. They further did a demo on how the system works.



The second presenter spoke on the theme: 'Diaspora Mapping and Collaboration Platform for Expatriates'. They  did a demo using data from SzekelyData. I don't know what that is.

The third guy presented on 'Mobile Application for Daily Challenge Management'.  He explained that the challenges to be managed should meet three different criteria.
  • Measurable
  • Finite
  • Scalable
The fourth presenter,  a team of two presented on the team: 'Taboo: Chord Sheet Editor and Manager Web Application'. This is a system that could be used to create sheet music chords from a piece of music. They did a demo using  Eric Clapson's Wonderful Tonight and show how you can generate the chord sheet using their application.

The fifth presenter made a presentation on a software system they developed under the theme: 'EKETour - Software Platform for Organizing Tours'.





My Research Tour Across Europe(Day 4) - SISY2018 Last Day of Conference in Subotica, Serbia



Today, Saturday, 15th September 2018 is the last day of the Conference in Subotica Serbia.
The program would conclude quite early and then we would go for lunch in some local place.

During the Session on Conceptual Intelligence, my friends Tamara Katic and Nemanja Milicevic presented a paper with title: 'Comparing Sentiment Analysis and Document Representation Methods of Amazon reviews.

Beautiful Tamara and Nemanja, both from the University of Novi Sad, Serbia.
Novi Sad is like the second most popular city in Serbia after Belgrade.



This is me at the reception of the Subotica, Tech

In this pics is a friend of mine, Silviu-Iulian Toc of the University Politehnica Polisoara, Romania. He presented a paper on Friday during the session on Intelligent Mechatronics and Intelligent Manufacturing Systems. The title of his paper is: 'Modbus-OPC UA Wrapper using Node-RED and IoT-2040 with Application in Water Industry'. He did quite well as the presented with Adrian Korodi of the same school.

We went to some local place for lunch along Kelebia road.



Some ancient fireplace I saw at the place, I've not seen this before

One thing I could remember is that a home-made wine called 'Palinka' was served.


7. A Review of the Conference
It’s been three long days of conference and now I’m just thinking to myself: ‘what have achieved, being here?’.
Sure I’ve achieved so much. These are just some of them:
  • Of course I presented my paper
  • I added a new country to the list of countries I've been to, Serbia
  • Connected with scholar from different universities including: Budapest University of Technology and Economics, Obuda University, Simon Fraser University, Vancouver, Subotica Tech and other

Research Objectives
The research would establish the performance trade-off of the .Net and the Java-based REST API implementation with respect to various parameters
  • Information system development time could be reduces
  • Well-defined basis for feasibility and performance
  • Right choice of API implementation technology

REST API Specification
  • Resource Identification via resource-based URIs
  • HTTP Methods
  • HTTP Status Codes
  • HATEAOS Compliance

Evaluation Criteria
  • Response Time
  • Code Complexity
  • Execution Speed
  • Throughput
  • Cost



REST Architecture
Explaining My Model by the REST Architecture

The REST Architecture for Mobile Services Application
Conclusion
Java-based APIs would be suitable for B2B scenarios such as Online Transaction Processing (OLTP) applications that periodically transfer data across data stores
APIs developed using the .Net Framework for OLAP scenarios requiring frequency and successive updates
Since data-driven applications are created using modular approach, each module could be developed based on requirements

Limitations of  the Study
  • Use of Generated Data
  • Focus of only response time
  • Limited Data Size
  • Simulated Environment




My Research Tour Across Europe(Day 2) - SISY2018 Conference Day 1 in Subotica, Serbia



This is the first day of the conference.
But guess what, the programs starts by sometime by noon! So I have some time to make this write up for you and maybe let you know what the day's activities would look like. And sure I have get to the venue early.
First, I need to look for a breakfast.


2. The Sights and Sounds of Serbia
Before now, I use to associate Serbia to the First World War. But right now, I am on ground and could not see anything that relates this beautiful city to any kind of violence as everywhere is quite peaceful. Take a look at some of the shots.



3. At the City Hall
This is the City Hall, where the first part of the program would take place. So I did the necessary registrations here

4.  Registration and Opening Ceremony
Just a formal process of registering the attendees. We receive our badge and conference pack containing a flash drive and the booklet. Was kind of boring though but it’s part of the initial procedures. I made some friends here.
Professor Levente Kovacs made a speech highlighting the benefit of the conference. He mention that SISY  is a global conference organized in different countries including Africa, Asia and the Middle East.
Imre Rudas made some opening remarks as well.



5. Hightlights  of Plenary Session I (Prof. Philip Chen)
Professor Philip Chen of the University of Macau spoke on the theme: Board Learning System and Its Structural Variation.

He spoke about flat neutral network which helps to eliminate multiple layer neural network. Using so much technical jargon, he explained how the weight can be obtained for flat neutral network. I could clearly see that many of the attendees quickly became bored. He continued anyway and kept speaking and the screen was always filled with cryptic formulas.

He mentioned that Moore’s Pseudo-inverse or gradient descent can be used to obtain solution. Then the mentioned something on sparse-coding, but the explanation was not quite clear to me. 
He also discussed the concept of Broad Learning difference from Deep Learning as well as incremental learning where the following parameters were used.
  • 60000 training samples 
  • 10000 learning samples 
  • Manifold Learning 
How to deal with noisy data - by normalization 



The session chair, Prof. Imre Rudas then asked him: In one sentence, 
Deep Learning: A neutral network that tries to map the inputs to the output using multiple hidden layers

6. Highlights of Plenary Session II (Prof. Ljiljana Trajkovic)
Prof. Ljiljana Trajkovicj of the Simon Fraser University, Canada spoke extensively on 'You and Your Career'.

She started by talking about her career history. She works in the Communications Laboratory at Simon Fraser, Vancouver, British Columbia, Canada.
She spoke about the role of education in our lives and careers. She encourages the audience to try to do their best.

This presenter has a very rich academic and research profile including:
  • Member of Technical staff in AT & T Bell laboratories
  • Research Scientist in Bell Communications Research
  • Visiting prof. at UC Berkeley
  • Prof. Simon Fraser University
Did so much work in communication network including:
  • Modelling and analysis of computer networks
  • Analysis of complex systems and network
She has been a lecturer in nine different subjects in Communication Networks as well as Circuit and Systems
She referenced another presentation with the title 'You and Your Research' and emphasized the need for good preparation so that if the opportunity comes, then you can seize it.

She emphasized the need to develop very good communication skills
She highlighted 5 factors most influential people adopt to rise to the top according to 204 British CEOs
Some of them are:
  • Ability to work with a variety of people
  • Responsibility in in important tasks
  • Need to achieve results
She the talked about IEEE as a non-profit Organisation governed by US laws
IEEE as of the time of this conference has 374,778 members including 41,677 graduate students
She encourages everyone to join professional organization including Young professional organization and Women in Engineering

7. Highlights of Plenary Session III (Prof. Sonja Ristic)
Prof Sonja Ristic spoke on Model- Driven and Domain Specific Language Paradigms in Information System (Re)Engineering Projects
She started by talking about herself. She is a professor in the University of Novi Sad, Faculty of Technical Science.
She say ‘a model is worth more than a thousand words ‘
She highlighted that there are different kinds of people, six categories:
  • Problem solvers
  • Dreamers
  • Researchers
  • Innovator
  • Creator
  • Tester


She talked about Software Engineering as a relatively young field. Also mentioned that software engineers are impatient an often times does not design along with users.
She says that software is abstract while real world is concrete but the says that this statement is not completely factual
She focused on Model-Driven Paradigm
She the mentioned and discussed Multi-Paradigm Information System design tool
She the summaries by highlighting Architecture Driven Modernization mentioning 9 key points:
Model-Dirven paradigms
...
...
She makes a strong statement ‘Engineers must be Responsabile’
If a builder builds a house and does not construct it properly and the house collapses and kills someone, the the builder must be put to death

Article 229 of the code of Hermurabi


9. Back to Hotel Room
Yeah! I’m back to my nice hotel room looking back at the day’s activities. That is me just relaxing as I already had more than enough at the banquet. So I never bothered calling the kitchen

10. Nice Supper and a Good Night Rest!

My Research Tour Across Europe(Day1) - Budapest to Serbia and Back to Budapest!

The Conference is the 16th International Symposium on Intelligent Systems and Informatics and I have been scheduled to attend. It holds in the city of Subotica in Serbia from 13-15th of September 2018. It is titled SISY2018

Let me tell you about this epic trip.
I would also tell you how the Serbian police refused me entry into Serbia and sent me back to Budapest, Hungary.


Leaving Home
It was a beautiful Wednesday, morning and the weather forecast for the day was quite good at a temperature or about 20 degrees.
I took my breadfast of rice and egg source and took off to the busy Keleti Train Station
This is my little home and I'm all ready to go.
This is my little home and I'll really miss playing my keyboard


This is me and sure I'm all ready to leave so let's make it to the train station.

The Keleti Payaudvar railway station is quite busy and I'll be catching a train by 11:57.
I hopped into the train an I have a room all to myself. And to tell you the truth, this is my first time making an international journey by train,


Just a little about Budapest, this tram car is said to be the longest tram-car in the world. I've not confirmed it though.
Longest Tram Car in the World- Budapest Tram 4-6
I would also show you around on the smooth ride so far from Budapest to Serbia. I took some pictures of some towns along the line.


The initial part of the train ride before thing started going wrong



Stepped  outside my cabin  


With some friendly passenger travelling to Serbia


Sleeping baby in the cabin, I could not speak so loud as I don't want to wake up the sleeping child.

Then I'm Refused Entry into Serbia
First, I was not with the original of my Hungarian residence permit. So when we got to the Hungarian border town of Kelebia, the border police requested for my document, so I explained I'm not with the original so I provided a copy. They accepted, and after some check in their office, they could see my records were ok. So they stamped my passport and we moved on.


Then we entered Serbia at the border police checkpoint. They asked for the same thing, I explained that I just have a copy. The policeman says he needs to original and I pleaded that he should check their database for my records. This did not work and he insisted that I would not enter the country and must go back to get the original document. All effort by his assistant failed and all of a sudden, I'm on a train going back to Budapest after touching Serbia.

 Its so sad that I need to go all the way back just to get the original of a document.


This  is so sad
I arrive Budapest at about 9 pm. I prepare some rice and egg source and got a little chicken from the fridge. Took my supper, slept off and was ready for the next day

When I did some little finding, I figured out that:
  • Serbia is not a member of the European Union
  • Serbia is not one of the Shengen Countries
So I get the point now. They don't have access to international records of citizens of the EU countries
This is the end of the First Day, I would provide you with update for each day. Thanks for reading

Thanks to the my supervisor Dr. Peter Martinek and thanks to the organizers of The Conference, 16th International Symposium on Intelligent Systems and Informatics- SISY2018
