Movement Classification and Analysis from RGB – D Video Data
(2019-05)The aim of this thesis is to develop and evaluate methods of human movement classification using motion tracking data captured using a RGB-D sensor. As hardware solutions evolve and improve, so too must the software solutions ... -
Solving Cyber-Alert Allocation Markov Games with Deep Reinforcement Learning
(2019-04-19)Most large scale networks employ some kind of intrusion detection software on their computer systems (e.g., servers, routers, etc.) that monitor and flag suspicious or abnormal activity. When possibly malicious activity ... -
Securing the ADS-B Protocol for Attack-resilient Multiple UAV Collision Avoidance
(2019-04-11)The Automatic Dependent Surveillance-Broadcast (ADS-B) protocol is being adopted for use in unmanned aerial vehicles (UAVs) as the primary source of information for emerging multi-UAV collision avoidance algorithms. The ... -
Dynamic Unbounded Integer Compression
(2016-07-22)One of the important applications of data compression is inverted indexes compression, which is a lossless compression. Presently, most of the internet search engines such as Google and Wikipedia process a large amount of ... -
Distributed Symbolic Execution For Property Checking
(2017-04-20)Symbolic execution is a powerful technique for checking properties in the form of assertions. It can systematically explore the program’s state space to find paths to assertion violations, and provide users with a ... -
GPU Execution Tracing and Compression
(2017-04-13)Program tracing is widely used for debugging and performance optimization. Whenever a program is traced, the overhead in terms of extra runtime and in terms of storage for the generated trace information are a concern. ... -
Data-transformation algorithms for minimizing bit flips on GPU data buses
(2017-07-24)Excessive power consumption and cooling costs in computing centers as well as limited battery life in mobile devices make energy optimization an important area of research. In CMOS technology, dynamic energy is primarily ... -
