Embedding Students and Educational Content from Online Courses
Students in online courses generate large amounts of data that can be used to personalize the learning process and improve quality of education. The goal of this work is to build a representation of students and educational content that can be used for a variety of tasks, such as content recommendation and classroom analytics. We formulate this problem as a regularized maximum-likelihood embedding of students, lessons, and assessments from historical student-module interactions. An empirical evaluation shows that this approach captures and predicts students' assessment outcomes more accurately than a simple baseline model.

Automating Perforator Flap MRA Reporting
Magnetic resonance perforator flap angiography reporting is a meticulous process which results in detailed reports providing surgeons with a great deal of information for preoperative planning and operating room decision support in cases of surgical breast reconstruction after mastectomy. The amount of time required to generate such a report is staggering. Our goal is to automate much of this process through a custom plugin for the OsiriX DICOM viewer, allowing the radiologist to focus on candidate perforator identification and spend less time on busywork. Some of the plugin's features are automated perforator notation, projecting perforator locations to the skin, intramuscular length estimation, perforator diameter and course visualization in the coronal plane of a 3-dimensional volume rendering, fat volume estimation, and standardized report generation featuring text and images. The implementation has reduced reporting times by roughly 75% from original manual methods, reduced the frequency of reporting errors, and increased surgical lead time, all of which contribute to improving efficiency in the operating room and decreasing the risk of complications.

Signature of Communication Graphs
A network graph was built to represent the communication network at Cornell University. This graph consisted of communications between people through the Internet. By developing “signatures” for the nodes, the network traffic was examined for any malicious behavior. There are three fundamental properties that define a signature in a communication graph - persistence, unique, and robustness. By implementing the signatures, Cornell University’s network traffic was analyzed within a certain time frame.

Rapid Circuit Prototyping
This is a pen plotter that draws in electrically conductive ink to rapidly create circuits drawn on a webapp. We created a rapid prototyping machine for electrical circuits by repurposing an old pen plotter that we fitted with an electrically conductive pen. Our plotter utilized an atmega 1284P to control the x and y-axis motors, and to raise and lower the pen. We created a web app that allowed a user to draw out circuits quickly, and then send them to be printed out on our plotter over a wifi network as our host computer that maintained the serial connection with the atmega 1284P. The atmega 1284P would receive vectors of x and y coordinates from the host computer that would instruct it on how to move the plotter head. By measuring the position of the plotter head on each axis through the on-chip ADC and two servo potentiometers, we were able move the plotter head to an accuracy of approximately 1/10th of an inch on a typical piece of A4 paper. With a single pen and only using conductive ink, each sheet of paper can contain only planar circuits. To facsimile multi-layer printed circuit boards (PCBs), we designed the circuit drawing application we made to track which traces are overlapping and to assign them to different virtual layers. The CPU would then send over chunks of vectors in groups we will refer to as “files” based on which layer they were on. A new file would be sent each time the user indicated that they had placed a new piece of paper on the plotting area via a button on the printer . By treating each layer as a new file, the user would end up with a different piece of paper for each layer of the circuit. By using through-hole components and solder paste, stacking these different sheets of paper is analogous to printing a multi-layer PCB.

Building Glasses-free 3D Displays for Angle Sensitive Pixels
Our research pertains to the construction of a 3D display that can display light fields created from ASP data. Light fields are a relatively new technology that captures additional information during picture taking, and allows for the reconstruction of an image at an entirely different focus or depth from the same position. We have focused on building an inexpensive 3D display and coding a software pipeline via Matlab capable of showing both synthetic images and those from ASP data. We achieved both aims and successfully visualized images in 3D with a glasses free light field display. This has novel implications with regard to creating and displaying 3D content on a scalable level with a potential for future widespread adoption.

Semantic Legal Information Systems
The Code of Federal Regulations codifies federal regulations about subjects ranging from nuclear waste disposal to butter pasteurization temperatures to the price of the print edition of the Code of Federal Regulations. It is a sprawling corpus (nearly 100 million words) organized according to federal agency structure. This project aims to improve access to these regulations by using topic modeling techniques to create a subject index for the CFR and the Federal Register (which publishes the regulations that are compiled in the CFR). This subject index will support topic visualization and browsing by subject on the LII web site, which serves 25 million people each year.

Visualising the Law of Fracking
A discussion on the topic of natural gas mining via hydraulic fracturing (aka fracking) typically involves many competing and overlapping geological, geographical, sociological, economic, policy, and legal dimensions, among others. This project aims to provide an extensible, interactive visual representation of the law of fracking focusing on the state of California. It also provides an interactive and powerful information retrieval engine on top of legal text which enables topic modelling and querying.

Detection of Attacks on Web Servers
Primary aim of our project is detection and filtering of possible attacks on web servers that include SQL injections, CSS attacks, scripting attacks, file injections etc. Attacks are detected through a language detection engine that identifies the programming language domain of the attacks; and sends them to a host based intrusion detection system. Here we play potentially malicious HTTP requests in one or many application servers hosted on honeypots and determine its anomalousness based on the health of the honeypots.

Configuring Live Distributed Applications by Solving Optimization-Constraint Problems
The cloud environment is highly dynamic and unstable due to variation in load, possible failure of computer nodes, relocation and virtual machine into a different physical node and fluctuations in network traffic during peak hours. The project is aimed at applying Optimization Constraints to dynamically configure cloud applications. This allows the user to specify management policy as a Linear/Quadratic problem which can be a meaningful and efficient way to configure cloud applications.
