An Investigation Of Match For Lossless Video Compression, Brittany Sullivan-Reicks
Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research
A new lossless video compression technique, Match, is investigated. Match uses the similarity between the frames of a video or the slices of medical images to find a prediction for the current pixel. A portion of the previous frame is searched to find a matching context, which is the pixels surrounding the current pixel, within some distance centered on the current location. The best distance to use for each dataset is found experimentally. The matching context refers to the neighborhood of w, nw, n, and ne, where the pixel in the previous frame with the closest matching context becomes the …

A Stand-Alone Dna Hybridization Detection System, Sinan S. Sayood
Department of Electrical and Computer Engineering: Dissertations, Theses, and Student Research
The goal of this project was to design a portable device that can quickly and accurately detect the difference between single and double stranded DNA. This was accomplished by analyzing the capacitive properties of DNA solutions and implementing a charge-based capacitive monitoring system to detect and analyze the solutions. The detection system was designed without reliance on expensive functionalized electrodes, and instead is able to detect the properties of free- oating DNA. This approach greatly reduces the cost of the materials needed to construct the device. It also decouples the main sensor apparatus from the bulk of the electronics, reducing …

When compared to traditional surgery, laparoscopic procedures result in better patient outcomes: shorter recovery, reduced post-operative pain, and less trauma to incisioned tissue. Unfortunately, laparoscopic procedures require specialized training for surgeons, as these minimally-invasive procedures provide an operating environment that has limited dexterity and limited vision. Advanced surgical robotics platforms can make minimally-invasive techniques safer and easier for the surgeon to complete successfully. The most common type of surgical robotics platforms -- the laparoscopic robots -- accomplish this with multi-degree-of-freedom manipulators that are capable of a diversified set of movements when compared to traditional laparoscopic instruments. Also, these laparoscopic robots …
