Journal publication
I have manage to finish a first draft of the journal publication so far. I spent yesterday running tests and grabbing screenshots as well as generating graphs to add in to the publication. This morning I managed to finish up the writing of the journal. I've sent the draft to my supervisors for early feedback and awaiting a response.

Book Chapter
I'm still continuing to write the book chapter. I have finished writing half of the chapter and there is still plenty more work to go. I still need to finish off the key management and the data sharing sections of the chapter. Although moving slowly, progress is being made on it every day.

Developed HeartBeat System
I've managed to get a clearer ECG waveform on the app now. It's still not perfect but still there is work to be done. I've also implemented visualisation of the ECG in the Java Client application. The client can now view, copy, and even save the ECG visualisation to a PNG image file. Also, the client can print the ECG visualisation for offline viewing and analysis.
Also, I'm still working on implementing automated ECG waveform analysis. I'm currently reading a past student's thesis to get idea and have looked at MIT-BIH website. I can try to implement something once I get a clear ECG waveform from the app. I will be looking at my code again to see where I can improve and try to get a smoother curve.

Regarding my progress so far, I am currently doing plenty of writing. I have nearly finished writing the journal and still making progress writing the book chapter. The last few weeks were mostly spent reading literature and writing in parallel.

I also presented a demo of the heart beat system to the Chief Scientist at CSIRO where my supervisor and a number of other CSIRO members were present. It was recommended that I try to produce a clearer ECG waveform and learn to classify the ECG waveform to detect any arrhythmias. I was given a past student's thesis to read and get a better understanding of ECG waveforms. It was also recommended that I look at 'MIT-BIH' as a reference for classifying ECG waveforms. Currently I am reading through the papers and will later change my application to incorporate these ideas.

Also, this week I attended the CSIRO ICT conference for a short while and met a few other PhD students working on different projects. Also, this week I submitted the first milestone deliverable to Rafael.

Reading Literature and Writing Papers

After developing the app, I have started writing a journal paper on it. I'm targeting the Future Generation Computer Systems (IF=1.978) Special Issue on Integration of Cloud Computing and Body Sensor Networks. So far I have written a full draft of the paper with some testing still left to complete. At the moment I have about 9 pages and trying to push for another 3 or 4 pages.

Also, I have been invited by my supervisor to contribute a book chapter for "Security, Privacy and Trust in Cloud Systems". I have submitted a proposal and now working on the writing of the book chapter. I realise I have a long way to go to finish the chapter. Working at fast pace..

Regarding the health-monitoring system, it is now a functional prototype and I will be giving a demo this Friday. The Android app now successfully connects the sensor via Bluetooth and reads the live streaming data. The app also has a user interface and buttons that will allow periodic uploads of the latest streamed data to the Cloud. The web service has been updated to allow user authentication. I've also created a Java application which runs on the Client's computer that will enable either a doctor or a patient to log-in and view ECG data through calls to the web service. At the moment, the security layer hasn't been implemented, and it is sending credentials and data through plain XML. Later on, I will implement a security layer that will incorporate secure data sharing aspects. I have come up with a draft idea of a data sharing protocol which will later be further refined. The protocol will be discussed in detail in the journal.

Much more work ahead...
