Cis Map Drawer Visualization System, Hanye Xu, David Ebert
The Summer Undergraduate Research Fellowship (SURF) Symposium
U.S. Citizenship and Immigration Services (USCIS) is the government agency that manages immigration to the United States. They are not only working on filing documents, but also analyzing those data they have. They require help from a visualization system to know the trend of immigration among offices across the country over time. We developed a project called CIS Map Drawer that is used to help build a visualization system for USCIS in order to analyze immigration data easily. This system makes use of a map view, a calendar visual representation, line charts, pixel drawing and other analysis tools to improve …
D-Tunes: Configuration Engine For Geo-Replicated Cloud Storage, Jiawei Wang, Sanjay Rao
D-Tunes: Configuration Engine For Geo-Replicated Cloud Storage, Jiawei Wang, Sanjay Rao
The Summer Undergraduate Research Fellowship (SURF) Symposium
When developing a web-based application, developers are facing stringent requirements to balance the latency, scalability and availability for their cloud database. Application developers need a specific replication configuration strategy based on the requirement of their application. To deal with this problem, some geo-replicated cloud strategy systems have emerged recently, like Cassandra. This project serves to design a web tool that can help configure the best replication strategies for geo-distributed data stores, which uses quorum-based protocols. Currently, our web tool D-Tunes, require a minimum input from users and generate specific scripts based on the inputs user provided. The program running these …

Is Real-Time Mobile Content-Based Image Retrieval Feasible?, Colin G. Graber, Anup Mohan, Yung-Hsiang Lu
The Summer Undergraduate Research Fellowship (SURF) Symposium
Content-based image retrieval (CBIR) is a method of searching through a database of images by using another image as a query instead of text. Recent advances in the processing power of smart phones and tablets, collectively known as mobile devices, have prompted researchers to attempt to construct mobile CBIR systems. Most of the research that has been conducted on mobile CBIR has focused on improving either its accuracy or its run-time, but not both simultaneously. We set out to answer the question: is real-time CBIR with manageable accuracy possible on current mobile devices? To find the answer to this question, …
Absorption Simulation ( Absim ) Software Development, Vipul Vishnu Bhat, Ming Qu
Absorption Simulation ( Absim ) Software Development, Vipul Vishnu Bhat, Ming Qu
The Summer Undergraduate Research Fellowship (SURF) Symposium
Researchers working on air conditioning systems currently use a software called ABSIM ( Absorption Simulation ) to evaluate current absorption systems or simulate new system designs. ABSIM was developed at Oak Ridge National Labs in the 1980s and the latest platform it is compatible with is Windows XP. ABSIM is not compatible on newer platforms and is not very user friendly. A lot of the actions involved in using ABSIM aren’t very intuitive. The goal is to develop a more user friendly simulation program that is based off of ABSIM and see to it that the program can be deployed …

Open Cortex-M0™ Modular Debug Unit, Chuan Yean Tan, Matthew Swabey
The Summer Undergraduate Research Fellowship (SURF) Symposium
The debug unit of a modern digital system on chip (SoC) is a critical unit that allows users to monitor and analyze the chip’s activity that occurs throughout a SoC design. Selection of the debug unit’s correct feature set and architecture are critical to the success of the design. Debugging systems that exist have different architectures and are closely coupled to their host SoCs. As a consequence they are resource intensive to improve on due to the different nature of each SoC designs. Moreover, the bus protocols that allow the debug unit to interact with the SoC design are often …

Development Of Pneumatic Robot For Outreach, Eshamogbo E. Ojuba, John Lumkes
The Summer Undergraduate Research Fellowship (SURF) Symposium
To encourage the current generation of high school and middle school students to pursue careers in engineering, it is important to have challenging hands-on engineering activities for them. Such activities should be interesting, compelling, and, most importantly, educative. A mini-excavator was built for fluid power outreach, but this tool only demonstrates fluid power, without showing other important aspects of engineering. The tool being developed is able to demonstrate fluid power, as well as other important aspects of engineering, such as controls, electronics, and programming. This tool is an electronically-controlled device that allows the user control a pneumatic circuit, coupled with …

An Ant-Based Sensor Measurement Data Gathering System, Bolun Zhang, Dimitrios Peroulis
The Summer Undergraduate Research Fellowship (SURF) Symposium
Large-scale industries involved with a great amount of sensor measurements in their work are facing many challenges in data collection. Sensors are not on the same network; therefore each measurement has to be managed separately. Gathering all the measurement data to one terminal could be difficult. Once a measurement is obtained, it takes significant amount of time to process the data.The approaches our group takes here is to build a giant ANT wireless network that holds all the sensors’ measurements. To be more specific, every sensor has an ANT chip set up on its side. Each ANT chip is as …

Code Optimization For Phase Field Method, Sergio Andres Monsalve, Marisol Koslowski
The Summer Undergraduate Research Fellowship (SURF) Symposium
The Phase field model method for studying grain dislocation at atomic level after applying an external force to the materials being tested, enables simulate the behavior of different materials after applying stress. With the appropriate numerical method the simulation could change drastically the complexity of the algorithm. Finding the most accurate and stable numerical method for the phase field model give us a considerable improving in the performance of the code used to simulate the phase field dynamic dislocation in larger and more complex simulations can be performed. We made an statistic comparison between the different methods, comparing stability and …
