Full-Stack Change Management for Database Systems
… represent disruptive changes at both ends of the stack of a database system from the perspective of externally driven changes. We examine various families of database systems, including relational, NoSQL document and key-value stores, as well as distributed variants. The state-of-the-art approach …

Network and storage stack specialisation for performance
… in demand: contemporary network and storage stacks, as well as related APIs (e.g., BSD socket API) follow a `one-size-fits-all' design, heavily emphasising generality and feature richness at the cost of performance, leaving crucial hardware resources unexploited. Despite considerable prior …

On-Stack Replacement Across User-Kernel Boundaries
… this problem, one should move the networking stack out of the kernel and into the user space or networking hardware. Instead, we build upon an alternative approach, known as LakePlacid. LakePlacid mitigates the kernel-user boundary overhead issue by moving the most important application logic …

Computer Aided Analysis of Smoke Stack Designs
… analyze the statics and dynamics of steel smoke stacks subject to excitation by aerodynamic forces. The wind loads experienced by smoke stacks arise from various phenomenon, the most prominent of which are static drag load, vortex shedding, and atmospheric turbulence. The nature of these loading …

Characterizing and Optimizing the Networking Stack in Databases
… thesis focuses on the overhead from the network stack in the server. I characterize the contributions of different components in the database server to the end-to-end latency, focusing on the networking stack. I observe that in transactions involving a single read query, the server network stack …

Model-based design for full-stack robot manipulation
… also presents the groundwork for performing full-stack robot manipulation tasks and proposes extensions to make the system more usable and accessible to all.

DESIGN & DEVELOPMENT OF PLANAR SOLID OXIDE FUEL CELL STACK
… anode-supported Solid Oxide Fuel Cell short-stacks have been designed, assembled, tested and characterized. The design of the stacks and its components (frame, housing, interconnect, compressive and bonded seals) required a great attention to the materials properties (i.e. thermal expansion …

Automating Pre-Stack Migration Enhancement and Image Quality Analysis
… problems need to be treated before applying a stack. The ideal case of layers in ADCIGs should be flat without smear amplitude throughout all angles. Using this principle, I process one reflection at a time in each iteration by isolating it into a local window and then flattening it. Also, I …

Developing an Adaptive Threat Hunting Solution: The Elasticsearch Stack
… thesis proposes and evaluates The Elasticsearch Stack solution (ELK), an enterprise-grade logging repository and search engine to provide active threat hunting in a Windows enterprise environment. The initial phases of this thesis focus on the data quality, unsupervised machine learning, and …

Tropical Intersection Theory on Moduli Stack of Curve Coverings
We construct the moduli cone stack $\mathfrac{M}_\eta^\text{trop}$ of tropical \'{e}tale covers (i.e., coverings of twisted tropical curves). We define the tropical intersection theory on $\mathfrac{M}_\eta^\text{trop}$ and show that the tropical intersection theory agrees with the intersection …

Device Stack Optimization for Protonic Non-Volatile Programmable Resistors
… ions. This thesis aimed to optimize the device stack in four directions and demonstrated a symmetric WO₃-PSG-WO₃ structure in a CMOS-compatible process, with the help of circular transfer length model (CTLM), which efficiently examines the resistance properties of WO₃. We have explored: (a) …

Testing of a counter-flow, stack-type sawdust dryer
The objective of this research was to test a prototype sawdust dryer designed by Arrowhead Forest Products, a wood products firm based in St. Louis. The dryer is designed to be used by small to medium sized sawmills and pallet mills. A series of 50 one hour or longer trials were conducted to …

Lunar: A User-Level Stack Library for Network Emulation
… library that is created from the network stack portion of the Linux operating system. This allows real-world applications to link against a simulator, with Lunar serving as the bridge. For this work, an implementation of Lunar was constructed using the 2.4.3 version of the Linux kernel. …
