Modeling Multi-Grained User Preference In Location Visitation, Yingrong Qin, Chen Gao, Zhen Tu, Hongsheng Wu, Shuangqing Wei, Yue Wang, Lin Zhang, Yong Li

Faculty Publications

Location prediction acts as a fundamental service in today's location-based information platform, which helps users access locations satisfying their demands, improving both user experience and platform profit. Since users with unambiguous demands prefer specific locations while users with compound demands consider first regions and then specific locations, it is necessary to model multi-grained user preferences at different geographical scales. However, most of the existing works concentrate on user preferences at the location-scale only, which can not understand users traveling behaviors thoroughly. In this paper, we propose to model both the fine-grained user preferences at the location scale and the coarsegrained …

Chemistry Faculty Research & Creative Works

Bio electrocatalytic synthesis is the conversion of electrical energy into value-added products using biocatalysts. These methods merge the specificity and selectivity of biocatalysis and energy-related electrocatalysis to address challenges in the sustainable synthesis of pharmaceuticals, commodity chemicals, fuels, feedstocks and fertilizers. However, the specialized experimental setups and domain knowledge for bio electrocatalysis pose a significant barrier to adoption. This review introduces key concepts of bioelectrosynthetic systems. We provide a tutorial on the methods of biocatalyst utilization, the setup of bioelectrosynthetic cells, and the analytical methods for assessing bio electrocatalysts. Key applications of bio electrosynthesis in ammonia production and small-molecule synthesis …

Biodov: A Tool Used To Encourage Discovery In Bioinformatics Through Gamification, Gregory D. Johnson Jr.

Theses

Expressing big data in a meaningful manner is exceptionally difficult. Scientists often struggle with the visualization of data due to several limitations. Currently, many scientists use two-dimensional figures to display and analyze meaningful data. However, I believe using game design theory and game technologies, we can create more robust visualizations. These visualizations will allow scientists to easily communicate science to the masses and make better discoveries. Therefore, we introduce BioDOV (Biological Data Oriented Visualization). This tool will utilize game design principles to expand upon current visualization methods in the scientific community. Through this proof of concept, we will create the …

An Investigation Of Phase Change Induced Marangoni-Dominated Flow Patterns Using The Constrained Vapor Bubble Data From Iss Experiments, Unmeelan Chakrabarti, Ayaaz Yasin, Kishan Bellur, Jeffrey Allen

Michigan Tech Publications

Kinetic models of liquid-vapor phase change often implicitly assume that the interface is in equilibrium. This equilibrium assumption can be justified for large flat interfaces far from the source of thermal energy, but it breaks down when the liquid surface is near a solid wall, or there is significant interface curvature. The Constrained Vapor Bubble (CVB) experiments conducted on the International Space Station (ISS) provide a unique opportunity to probe this common assumption and also provide unique data and insight into phase change-driven flow physics. The CVB experiment consists of a quartz cuvette partially filled with pentane such that a …

Advances In Off-Resonance Distortion Correction For Echo Planar Imaging, Andrew Nathan Van

McKelvey School of Engineering Graduate Student Theses & Dissertations

Functional MRI (fMRI) data, acquired through echo-planar imaging (EPI), are consistently distorted by main (B0) magnetic field inhomogeneities which are driven by differences in tissue susceptibility. Traditionally, these distortions are corrected using separately acquired field map data, which provide an estimate of the B0 inhomogeneity. However, factors such as head position changes during scans, corrupted field maps due to movement, or even the absence of field map data can impede this correction process. In this work, we present two new solutions to address these challenges and evaluated them using several quality metrics (Chapter 2). First, Synth, a field map-less correction …

Grain and Other Field Crops Research Articles

Temperatures below or above optimal growth conditions are among the major stressors affecting productivity, end-use quality, and distribution of key staple crops including rice (Oryza sativa), wheat (Triticum aestivum), and maize (Zea mays L.). Among temperature stresses, cold stress induces cellular changes that cause oxidative stress and slowdown metabolism, limit growth, and ultimately reduce crop productivity. Perception of cold stress by plant cells leads to the activation of cold-responsive transcription factors and downstream genes, which ultimately impart cold tolerance. The response triggered in crops to cold stress includes gene expression/suppression, the accumulation of sugars upon chilling, and signaling molecules, among …

Reference Governor For Air-Conditioner, Ganiyu E. Azeez

Mechanical Engineering ETDs

Advanced control for heating ventilation and air-conditioning (HVAC) systems has primarily focused on optimizing energy efficiency. However, ensuring the safe and reliable operation of HVAC equipment is another crucial control objective. This Thesis presents a reference governor (RG) that can augment existing energy-optimized controllers with the capability to enforce constraints to ensure safe and reliable operation. The RG makes minimal adjustments to the reference room temperature setpoint to ensure that the refrigerant entering the compressor is super-heated, thereby preventing potential damage. Designing the RG requires synthesizing a constraint admissible positive invariant (CAPI) set which characterizes the subset of states for …
