The current Internet architecture reveals its chronic limitations against the new paradigms of networking. The advancement of technology has changed the network use from communication to content distribution. Unfortunately, the IP-based...
DAGDA exposes some of the hidden operations that the hardware uses when performing loads and stores to the compiler to save energy and increase performance. We decouple the micro-operations for loads and stores into two operations: the...
The problems inherent to providing security for network systems are relative to the openness and design of network architecture. Typically network security is achieved through the use of monitoring tools based on pattern recognition or...
As storage device performance increases, the lifespan of an I/O request becomes throttled more-so by data path traversal than physical disk access. Even though many computer performance analysis tools exist, a surprisingly small amount...
Wireless mesh network is usually used to provide Internet access to communities or citywide. Opportunistic Routing (OR) exploits overheard packets in a wireless network and has been proven to be effective for wireless mesh networks....
Building more intelligent and more resourceful dialogue systems has been a long sought-after goal in Artificial Intelligence and Natural Language Processing. In this dissertation, we investigate two topics in deep learning based dialogue...
The Internet is composed of tens of thousands of network domains or Autonomous Systems (ASes), and Border Gateway Protocol (BGP) is the current de facto inter-domain routing protocol used by network domains to exchange reach ability of...
As the standard formalism and powerful abstraction of networked data, graphs have been used to model and interpret structured information from protein interaction and program dependence, to business coordination and Internet topology....
Using traditional methodologies and tools, the problem of keeping performance-critical kernels at high efficiency on hardware evolving at the incredible rates dictated by Moore's Law is almost intractable. On product lines where ISA...
This thesis is intended to cover two of the most basic, important and highly applied multiple access communication techniques in modern age. It will provide an in-depth literature on the history, evolution, present and future of FDMA ...
We are currently in the era of big data, where data of enormous volume and variety is generated continuously, and they need to be captured, processed, and analyzed at a high velocity. Many users have increasingly adopted big data...
This research provides theoretical and computational developments in statistical shape analysis of shape graphs, and demonstrates them using analysis of complex network-type object data such as retinal blood-vessel (RBV) networks. The...
In all areas of research, finding the correct limiting factor able to provide the largest gains can often be the critical path of the research itself. In our work, focusing on branch prediction, we attempt to discover in what ways did...
Low-rank matrix approximation is extremely useful in the analysis of data that arises in scientific computing, engineering applications, and data science. However, as data sizes grow, traditional low-rank matrix approximation methods, ...
