Mobile Application Authentication System:

The Ohio State Medical Center provides iPhones to students, staff, and faculty to facilitate faster and more convenient access to its services. The mobile application communicates with the services using a 40-digit Globally Unique Identifier (GUID) to authenticate the users. This system does not use a common framework and as a result is not scalable. The 40-digit GUID is difficult to generate, remember and save securely. MAAS provides a common framework for authenticating Medical Center users. The secured channel is guaranteed by MAAS by using OSU shibboleth authentication mechanism for all OSU users with OSU username and password. Click here for poster

iShoe:

The iShoe/eStadium project is a collaboration between The Ohio State University, University of Purdue, and Georgia Tech. The goal of iShoe is to improve the in-game experience for spectators by allowing access to features not normally accessible to fans.  Users can access all features of iShoe from their mobile devices during a home football game, the statistics for the current game are updated as the game is played.

The iShoe project follows a basic LAMP (Linux – Apache – MySQL - PHP) design. While this example implementation resides on a Red Hat Enterprise Linux server, any server capable of running Apache with PHP and MySQL support should be sufficient. The iShoe project makes use of NOAA (National Oceanic and Atmospheric Association) web services. These web services allow the iShoe application to display live weather information to its users. These web service requests are made possible by using SOAP (Simple Object Access Protocol) requests.

Following features were added to the existing project:

The administrative interface: this section was added to make the administrative effort required to maintain the application more manageable.

The news section: this feature contains the RSS feed functionality, and should be easily modified to use any RSS feed.

The documentation section: iShoe provided extensive documentation not only to the added features but for the existing system and code.

Heavy changes to the page classes: this was done because they're easily the most important classes in the application, and are essential to understanding how the application works.

The super administrator permission level has been added to the system, this level is needed to distinguish between administrators who maintain the system and those who can create other account in the system.

Numerous other changes were made to the system in order to convert the system to iShoe and to allow continued expansion on iShoe and collaboration between the universities. Click here for poster

Location Based Ad Management:

Eproximiti wanted to revolutionize the way advertising is done, by targeting local consumer base (i.e. allowing its paying clients to put up Ads and coupons specific to a region or location). For this the Ads, coupons, videos etc of eproximiti’s clients had to be updated manually by eproximiti admin. This model didn’t work if the number of clients are large and also if the number of locations registered by the clients are many. As a solution, an interface to the clients which allows them to manage their ads, coupons, videos etc for different locations was provided. This interface also allows the clients to view other information like demographics, statistics etc.

 The project implemented a layered architecture for the application.  It is divided into four layers,

1)  Presentation Layer - The presentation layer provides the application's user interface.

2)  Business Layer (BL) - The business layer implements the business functionality of the application.

3)  Web Services - The Web Services are used to fetch specific information needed for the business layer.

4)  Data Access Layer (DAL) -  The data access layer provides access to the database.

The user interface was one of the most important and difficult aspect of this project. We have designed a simple UI in an “L-shaped” format, with emphasis given to the functionality and ease of use. The checkbox list on the left hand side allows the customer to choose multiple locations and perform any of the functions specified on the top bar.MemCatch™ is a new software start-up that is developing a technology platform focused on enabling users to aggregate their knowledge into one place, in the cloud, where they can share and access knowledge throughout their social networks. The MemCatch Message Center project is focused on integrating common messaging applications with the knowledge base. This project integrates a universal message center with the MemCatch knowledge base in a way that allows all types of messages to become accessible knowledge pieces within the knowledge base.

The goal of this project is to build a module which allows the user to interact with the knowledge bins with email. The user will be able to add an email account and drag and drop emails from their preexisting email account to the knowledge bins which will convert the email to a knowledge bit. Click here for poster

Energy Efficient Homes and GIS:

This project creates a GIS application that allows a user to search and view parcels throughout Columbus.  Parcels will be displayed along with information pertaining to zones that are energy efficient in residential areas.

Energy Star homes are at least 15% more efficient than those built to 2004 International Residential Code. Should all new houses being built conform to more energy efficient standards, daily oil imports would be reduced by 6%.

The goal was to provide fast, easy-to-use search of all parcels located throughout Columbus, display by-parcel data that is pertinent to researchers who want to identify trends in energy efficiency. It will also provide a platform that will be a part of a larger project to increase community awareness about energy efficient building practices.

The task involved were to create user forms, data management along with Google maps to display relevant properties such as parcel ID, address, range of years over which a set of homes were built, home value range. Click here for poster

Selective Data Extraction:

The project aims at creating web services that allows an administrator to add patterns (set of html tags that surround the comments) into a database using which comments can be retrieved from URL’s.  User can provide feedback based on the comments retrieved and this helps the administrator modify/add/delete the patterns stored. Along with the comments text, the other details of comments like author name, comment title and time stamp should also be retrieved.

The Application provides authentication for both the normal and admin user and has a rich user interface. It allows new user registration. It lets the admin user view the source of any URL and to obtain the relevant patterns to extract comments. Provides a feedback mechanism which allows the application to correct the erroneous patterns. Handles multiple patterns for a single URL – providing UI feature to select the appropriate pattern for the given webpage.

The technologies used were Java 6, Tomcat, Axis 2 and  MySQL. Click here for poster

Bending Without Breaking: Versioning Web Services:

This project involved developing best practices in managing web services which have become a preferred paradigm for developing applications with reusable components which can be accessed by a variety of systems regardless of their platforms over a network such as the internet.

When these web services change, the clients consuming the service might stop working. This forces your customers to rewrite the client and to reconsider the cost of doing business with you. Not all changes need to break clients. With some planning, your services can be made flexible enough for future changes, without jeopardizing your customers’ applications. However, without a clear best practice, this is case-specific.

As a part of the project, a simple web service is implemented, changed, and documented the results for clients using .NET and Java EE.

This research on web service versioning has led us to create a best practices guide that could help a company design a service that would be flexible for future additions. When implemented correctly, these best practices allow users to take advantage of modified services while still reliably functioning for the customers that use previous versions. During the research, it was concluded that some changes just cannot be made without breaking all of the clients. Being able to distinguish between a breaking change and a non-breaking change would give a company the ability to gauge the effect of a change on a service, making it more reliable and less prone to rework.  By adopting best practices for service development, businesses can minimize developer and maintenance costs while paving the way for their future work.
