Innovation Aspects

Hello,

in addition to my thesis, I have to write a short paper about the innovation aspects of my work.

Please find my document here:
Innovation Aspects

If some more innovation aspects come to your mind, I would be happy to hear them. Feel free to comment.

I am back in Austria and working on the last corrections of the thesis. The final deadline is the first of September.

Cheers,
Tanja

HPU Talk

Aloha,

today I gave a talk about my semester abroad and my research work at HPU.

Here you can find my presentation online:
Presentation

Curt recorded the presentation. I hope he will be able to upload the video to youtube, then I can post it here ...

Cheers, Tanja

Temporary End Version

Hello,

here you can find my temporary end version of the thesis:

Thesis - Microsoft Word

Thesis - PDF

I tried to implement all the suggestions from you. Hope its fine like this.

• I tried to avoid using too many bullet points
  But I also did not delete all of them, cause I think sometimes they are useful for the clarity of the text

• I implemented the spelling and grammar corrections from Sam

• I updated the visualization part
  It is now possible to save visualizations and to load them again
  User story: a scientist wants to give his visualizations to his colleague, so that the colleague can also use them in his simulation

• I corrected the  sequence diagrams

I will put it all in Latech in summer. But at the moment, the microsoft word version is easier for me and I think for correcting too.

I am heading to San Francisco tomorrow and I will be back in Honolulu on 25th June.

Curt Powley (Chair of the Computer Science Department here) asked me to hold a talk about my thesis at HPU. It it expected to take place in the first week of July.

Cheers, Tanja

Update: Visualization

Hello,

this week I added two new visualization methods to my simulation (see code on Github).

Updated visualization screen with the following options: Curve, Pie Chart and Bars

 The bar view

The pie chart

It is now also possible to view more than one sensor/constructs with each visualization option for comparison.

Here is an example of the curve viewing data for humidity and temperature:

I am currently updating my documentation with your hints and suggestions.
Thanks very much for your help!!

One hint from Thomas, which I don't really understand is:
---
... you should again think about your scenarios and the COMBINATION of constructs. ATM, you thought of combinations as mathematical equations. Combinations can also mean the visual combination of several graphs (constructs). This would also be a 'construct' that could be used itself ...
---

How can I visually combine sensors? If two constructs are nearly the same, storing e.g.  the mean value of them?
A concrete example (like a user story) would be great. I think I don't really understand what you mean with visual combinations.

Thanks a lot!

Cheers, Tanja

Preview Thesis

Hello,

here you can find the preview of my thesis:

Thesis - Preview - PDF

Thesis - Preview - Microsoft Word

I would appreciate to know, if the direction I am heading to is right ... especially for the practical part (starting at chapter 7). Are some important parts missing?

Thanks a lot!
Cheers, Tanja

Simulation GIT

Hello,

after my simulation using the version control system SVN works, I implemented now the same with GIT.

I added a button called "Settings" on the simulation start screen.

When clicking the button, the settings can be chosen:

(I stored all the standard settings as default value).
When the settings for GIT are chosen, the text "GIT" is displayed on the top right corner of the start screen (instead of SVN) and when linking two constructs, a different windows service using GIT is started up.

I wanted to let the user chose, if the GIT version should store to the local repository or to the remote one on Github. I spend nearlly two full days browsing the internet and searching the source code: seems like it is not implemented to push to a remote repository while using the library Gitsharp.

So far, I experienced the following advantages/disadvantages with the two versioning systems:

I am currently working on the documentation of my practical implementation. I hope to be able to upload this document next week.

Cheers, Tanja

Data Visualization

Dear readers,

this week I started working on the visualization part.

After the sensor called "Humidity" is checked and clicking the button "Show" ...

... my visualisation mask pops up:

• Description
  Per default here stands the name of the selected sensor
• Destination
  The destination, where the sensor file is stored
• Data
  The current data in the sensor
• Refresh
  The user has to click this button for refreshing the sensor data
• Cancel
  Closes the mask
• Show
  A new window showing the visualization opens

Coordinate system:

The coordinate system shows the timestamps on the x-axis (displayed interval = 1) and the actual data on the y-axis.

At first, I was not sure, how to visualize data with C#.
I started with online research. I found some self-made graphics and wanted to draw a graph on my own. But this started to get really complicated ... so I restarted browsing the Internet and came up with a open source library from the website "Code Project":
http://www.codeproject.com/Articles/5431/A-flexible-charting-library-for-NET

I implemented this code in my project. It works really fine now :-)
(see project called "Simulation" on Github https://github.com/tantschi/masterthesis.git).

At the beginning, I wanted to implement two different visualization methods.
I did some research on the Internet/books, but I don't know, which second method I should implement for my kind of data?
My sensor files contain just a timestamp and a value, but nothing else (e.g. 25.04.2013 09:17:59;93).
So I am not sure, if I should implement a second visualization or better try to focus on the processing/mining of the data (the storage in a versioning system).

Concerning my last post: I am now able to store the content of the linked sensors in a new construct-file.
I use another library from Code Project called "Math Parser".
http://www.codeproject.com/Tips/381509/Math-Parser-NET-Csharp

It calculates the result out of my Link-text-field:

At the moment I link the two last lines in each text-file according to a given interval. I think it is quite hard to know which lines of two .txt-files with different sensor intervals belong to each other.
