Design of Low-Voltage and Low-Distortion CMOS RF Integrated Circuits Using Volterra Analysis
(2011-09-22)Analog circuits that operate with low voltage supply headroom generally suffer from poor linearity performance, poor noise performance, etc. However, with the aggressive scaling of the supply voltage in Complementary Metal ... -
Detecting PDF Javascript Malware Using Clone Detection
(2013-10-02)One common vector of malware is JavaScript in Adobe Acrobat (PDF) files. In this thesis, we investigate using near-miss clone detectors to find this malware. We start by collecting a set of PDF files containing JavaScript ... -
Detection and Grading of Prostate Cancer in Temporal Enhanced Ultrasound using Convolutional Neural Networks
Prostate cancer is the most common non-dermatological cancer amongst men in the developed world. The current definitive diagnosis is core needle biopsy guided by transrectal ultrasound. However, this method suffers from ... -
Developing Better Models for Dialogue Threads and Responses
In this thesis, we focus on developing machine learning algorithms to model human dialogues and conversations by investigating three basic tasks. We first study the development of retrieval-based chatbots, in which the ... -
Development and Automatic Monitoring of Trust-Aware Service-Based Software
