Storage as a Service(Saas) implemented using Python. The web application enables the user to log in and store encrypted files on IBM bluemix object storage. Users can also execute operations such as delete, download, list files and save multiple versions of file remotely.
The service is also implemented using IBM Bluemix ClearDB.
• IBM Bluemix, Python Flask.

The web application enables users to select admission diagnosis codes of the patients. The application further generates life tables and survival plots in order to predict the survival of the different patient groups based on the clinical decisions.
• PHP, Javascript, MySQL.

In this application, the user selects health condition and the demographics of a patient. On the basis of selected values, the user will be presented with information on the hospital characteristics of admissions of other patients who share similar conditions and have same demographics with the patient of interest.The useful information consists of factors such as length of stay, in-hospital mortality rate etc. The user can also compare how these factors vary across different healthcare… Show more
