Toritseju Omaghomi, Environmental Engineering, University of Cincinnati, Sizing Indoor Water Distribution Systems for Sustainable Water Supply. Designing indoor water distribution systems today requires a sustainable methodology that reflects the recent changes in water conservation measures. The current method is not flexible to recent water use changes. This research will provide a probability model with updated metrics to estimate water demand for right pipe sizing in buildings.

Development of index-based and value-based methods for sustainable manufacturing performance assessment at the systems level ranging from production line to plant and to enterprise levels. The alternate methods are developed based on hierarchical framework to investigate sustainable manufacturing performance metrics from the product and process levels.

Anna Prisacari, Human Computer Interaction, Iowa State University, Benefits of Applying User Experience Guidelines When Designing Technology to Promote Sustainability. How can the general public be encouraged to adopt sustainable technologies? In this presentation I will discuss several solutions that are designed to educate people about sustainability and environment. These solutions were tested with diverse user experience and cognitive methods, providing practical guidelines for how the design of products can be improved and encourage user adoption.

Ahmed Tukur, Mechanical Engineering, University of Dayton, Reducing Ventilation Energy Use in Buildings Via Statistically Informed Supply Pressure Control. Ventilation accounts for roughly 13.6% of a building’s energy consumption. In most buildings static pressure is constant and many zonal dampers are partially closed, thus wasting energy. Statistical analysis of the zonal damper positions is used to control the supply pressure for ventilation to realize savings between 11% and 50%.

Rodwan Elhashmi, Mechanical Engineering, University of Dayton. Borehole Thermal Energy Storage for Multifamily Residences. Multifamily residences are the least energy effective of all buildings in the U.S. In this study, a largescale Borehole Thermal solar Energy Storage (BTES) system design is developed to meet all heating and hot water demands in an apartment complex in Ohio. The resulting cost-optimal system can payback in 13 years.

Junling Xie, Mechanical Engineering, University of Wisconsin—Milwaukee, Energy Efficiency Improvement with Novel Structures Applied in Building Energy Storage Systems. Nowadays many different energy storage technologies have been widely applied in building energy management, such as ice thermal storage for the cooling energy control and battery energy storage for the electricity control. In my research, novel structures have been innovated and experimentally analyzed to improve the technical performance of two building energy storage systems.

Syeda Saria Bukhary, Civil Engineering, University of Nevada, Las Vegas, Water Usage for Solar Power Development in Semi-arid Nevada. This study analyzed the water requirements and availability, reduction in carbon emissions as well as land usage of solar installations by using a system dynamics model, for the state of Nevada to meet the goals of renewable portfolio standard during the period 2010-2030.

Mahboobe Mahdavi, Mechanical Engineering, Temple University, Numerical Analysis and Experimental Validation of Heat Pipe Network Performance Developed for High-Temperature Latent Heat Thermal Energy Storage Systems. In the current study, the thermal-fluid phenomenon inside a novel heat pipe network is investigated numerically and experimentally. The heat pipe is specially configured to be implemented in thermal energy storage units for concentrating solar power generation systems.

Laura Solomon, Mechanical Engineering, Lehigh University, Heat Transfer Within Encapsulated Phase Change Materials — The Void Effect. An internal void space is required within an encapsulated phase change material capsule to accommodate the volumetric expansion of a phase change material upon melting and prevent rupturing. The effect of the location of the void space on the heat transfer within encapsulated phase change material capsules was numerically studied.

Raqibul Hasan, Electrical Engineering, University of Dayton, Memristor Based Low Power Circuits and Systems. There is strong demand for extreme low power computing architectures for the emerging big data applications. The memristor is a novel device having a large varying resistance range. Physical memristors in a crossbar structure can evaluate many multiply-add operations in parallel in analog domain which are the dominant operations in neural network applications. Objective of this research is to examine memristor based extreme low power neuromorphic architectures for big data processing.

Sidaard Gunasekaran, Aerospace Engineering, University of Dayton, Relationship Between the Free Shear Layer, the Wingtip Vortex and Aerodynamic Efficiency. Most airplanes today do not operate at maximum aerodynamic efficiency. The relationship between the free shear layer and the wingtip vortex in the wake of a 2-D and 3-D wing was determined in order to effectively manipulate the maximum aerodynamic efficiency of the airplane to occur at operating conditions.

James Allen, Mechanical Engineering, University of Alabama, Preheating Effect on the Flame Structure of a Swirl Stabilized Combustor with Porous Insert to Control Thermoacoustics. Lean premixed (LPM) combustion is a common strategy in the turbine industry for power generation to reduce emissions, but tends to produce thermoacoustic instabilities under specific conditions. Using time-resolved OH planar laser-induced fluorescence technique, the stabilized flame structure without and with the porous insert is observed under preheated conditions.

Diego Felipe Garcia Mina, Electro-Optics, University of Dayton, Nanometer Metal Films on Tapered Optical Fibers to Enhance Environmental Sensing Capabilities. Using a tunable laser we analyze the optical signal transmission through a bi-tapered fiber sensor. The device sensitivity can be increased by depositing a gold metal film a few nanometers in thickness on the surface. By attaching selected molecules to the surface we can determine the presence of specific biomolecules.

Matthew Rosenberger, Mechanical Science and Engineering, University of Illinois at Urbana-Champaign, Probing Local Thermal, Mechanical and Optical Properties Utilizing Dynamic Cantilever Response in Contact Mode Atomic Force Microscopy. This work describes the use of atomic force microscopy to measure nanometer-scale material properties by observing surface deformation in response to a stimulus (e.g., heating or mechanical force). Three measurement applications are presented: thermomechanical deformation of AlGaN/GaN transistors, infrared absorption of individual carbon nanotubes, and mechanical properties of polymers.

In this research, different wireless sensor configurations have been developed based on the frequency conversion principle. A passive wireless pitch-catch system, a microwave and solar powered wireless Acoustic Emission sensor, and a wireless tomography system which do not rely on any external power source are some of the achievements.

My project utilizes DNA sequencing technology to identify and investigate microbes with plant-degrading enzymes in the deep ocean. The deep ocean is known to possess a broad and uncharacterized diversity of enzymes that likely include those that degrade plants. These enzymes would benefit biofuels and address a major knowledge gap.

Biochar is a low-cost, sustainable sorbent for removing organic contaminants in water treatment applications. However, the relationship between its production conditions and sorption behavior is poorly understood. I am evaluating how production conditions govern biochar properties to better understand sorption phenomena and how to optimize the production of biochar sorbents.
