A Laboratory Method for Measuring the Heat Distribution of Luminaires and Its Application for Building Heating and Cooling Energy Saving
(University of Kansas, 2019-05-31)This study was aimed to explore the energy saving potential of a new system architecture of solid-state lighting fixtures that was designed to help utilize the heat generated by LEDs for spacing heating in heating season ... -
Linking Best-Value Procurement with Project Performance Outcomes in Design-Bid-Build Vertical Construction Projects
(University of Kansas, 2018-05-31)Construction is a dynamic process in which the outcomes depend on the quality of the project team; therefore, awarding the project to the best-suited contractor an important decision for owners. One method of contractor ... -
Towards industrial large eddy simulation using the FR/CPR method
(University of Kansas, 2019-05-31)NASA’s 2030 CFD Vision calls for the development of accurate and efficient scale-resolving simulations for turbulent flow, such as large eddy simulation (LES) and direct numerical simulation (DNS). This is primarily because ... -
Sulfate Reduction in Produced Water via Expanded Granular Sludge-Bed Reactors
(University of Kansas, 2019-05-31)In 2012, an estimated 890 billion gallons of produced water were generated for all U.S. onshore and offshore oil and gas production sites (Veil, 2015). Reusing produced water seems beneficial for oil companies, but may do ... -
Securing CAN-Based Cyber-Physical Systems
(University of Kansas, 2019-05-31)With the exponential growth of cyber-physical systems (CPSs), new security challenges have emerged. Various vulnerabilities, threats, attacks, and controls have been introduced for the new generation of CPS. However, there ... -
Waveform-Diverse Stretch Processing
(University of Kansas, 2019-05-31)Stretch processing with the use of a wideband LFM transmit waveform is a commonly used technique, and its popularity is in large part due to the large time-bandwidth product that provides fine range resolution capabilities ... -
Modeling Discretionary Lane Changing Decisions for Connected Vehicles Based on Fuzzy Logic
(University of Kansas, 2019-05-31)Lane changing is one of the most complex tasks during driving. Advances in vehicle technology seek to help drivers during the lane change maneuver. Researchers have conducted many attempts to address this issue. However, ... -
Scattering Analysis and Ultra-Wideband Radar for High-Throughput Phenotyping of Wheat Canopies
(University of Kansas, 2019-05-31)Rising the yield of wheat crops is essential to meet the projected demands of future consumption and it is expected that most yield increases will be associated to improvements in biomass accumulation. Cultivars with canopy ... -
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 ... -
