MSRR: Leveraging dynamic measurement for establishing trust in remote attestation
(University of Kansas, 2019-05-31)Measurers are critical to a remote attestation (RA) system to verify the integrity of a remote untrusted host. Runtime measurers in a dynamic RA system sample the dynamic program state of the host to form evidence in order ... -
Understanding the Direct Conversion of Glycerol to Ammonia
(University of Kansas, 2019-05-31)The production of biodiesel has increased exponentially in the past few decades. This growth has facilitated an excess creation of glycerol, which is generated as a byproduct during the formation of biodiesel. As a result, ... -
Subchondral Bone Cysts - Filling the Void
(University of Kansas, 2019-05-31)Subchondral bone cysts (SBCs) are voids that can occur in the bones of young horses, especially horses intended for performance. Believed to be caused by trauma or osteochondrosis, these defects most often occur in the ... -
New Three Phase Photovoltaic Energy Harvesting System for Generation of Balanced Voltages in Presence of Partial Shading, Module Mismatch, and Unequal Maximum Power Points

Investigation of Variations in Corrosion Potential in Mechanically Stabilized Earth Backfill Due to Migration of Fines
(University of Kansas, 2019-05-31)Departments of transportation have constructed thousands of mechanically stabilized earth (MSE) walls to support bridge abutments in highway projects and for other applications. These MSE walls often include metal strips ... -
AUTONOMOUS SURFACE DETECTION AND TRACKING FOR FMCW SNOW RADAR USING FIELD PROGRAMMABLE GATE ARRAYS
(University of Kansas, 2019-05-31)Sea Ice in Polar Regions is typically covered with a layer of snow. The thermal insulation properties and high albedo of the snow cover insulates the sea ice beneath it, maintaining low temperatures and limiting ice melt, ... -
Probabilistic graphical techniques for automated ice-bottom tracking and comparison between state-of-the-art solutions
(University of Kansas, 2019-05-31)We present improvements to existing frameworks for automated extraction of ice interfaces applied to two-dimensional and three-dimensional radar echograms of polar ice sheets. These improvements consist of novel image ... -
Stability and Control Derivatives Identification for an Unmanned Aerial Vehicle with Low Cost Sensors Using an Extended Kalman Filter Algorithm
(University of Kansas, 2019-05-31)Unmanned aerial systems (UASs) tend to be autonomous vehicles. Thus, they require control algorithms. More advanced control algorithms can be developed when high quality UAS dynamic models are available. It is common to ... -
Diagonally-Reinforced Concrete Coupling Beams with High-Strength Steel Bars
(University of Kansas, 2019-05-31)The use of high-strength steel in diagonally reinforced coupling beams was investigated with the aims of minimizing reinforcement congestion and increasing the maximum permissible design shear stress without compromising ... -
ARRAY PROCESSING TECHNIQUES FOR ESTIMATION AND TRACKING OF AN ICE-SHEET BOTTOM
(University of Kansas, 2019-05-31)Ice bottom topography layers are an important boundary condition required to model the flow dynamics of an ice sheet. In this work, using low frequency multichannel radar data, we locate the ice bottom using two types of ... -
Downlink Achievable Rate Analysis for FDD Massive MIMO Systems
(University of Kansas, 2019-05-31)Multiple-Input Multiple-Output (MIMO) systems with large-scale transmit antenna arrays, often called massive MIMO, are a very promising direction for 5G due to their ability to increase capacity and enhance both spectrum ... -
Heuristics to predict and eagerly translate code in DBTs
(University of Kansas, 2019-05-31)Dynamic Binary Translators(DBTs) have a variety of uses, like instrumentation, profiling, security, portability, etc. In order for the desired application to run with these enhanced additional features(not originally part ... -
Resource Allocation in Multi-user MIMO Networks: Interference Management and Cooperative Communications
(University of Kansas, 2019-05-31)Nowadays, wireless communications are becoming so tightly integrated in our daily lives, especially with the global spread of laptops, tablets and smartphones. This has paved the way to dramatically increasing wireless ... -
