Challenges And Opportunities Of Applying Digital Public Participation Tools In Urban Development Projects In Egypt., Areej Kiwan, Sherif Sheta, Mina Samaan

Mansoura Engineering Journal

Despite the rapid social and informal-urban growth which causes a lot of problems in urban and rural settlements in Egypt, the lack of both stakeholders’ coordination and genuine public participation cause additional issues. Nowadays, many cities in Egypt, including the capital, suffer from the lack of real public participation in the decision-making of urban projects which results in conflicts among the government, the public and even experts opposing these decisions. All over the world, many participation models have been adopted in urban planning and development projects with different levels and forms of public participation. Where public participation is a requisite, …

Effat Undergraduate Research Journal

This paper focuses on the way in which children’s language and personal experience develop when they are identified as Cross-Cultural Kids (CCKs) or Third Culture Kids (TCKs). Globalization played a role in increasing the number of CCKs and TCKs. As a result, many research papers have discussed this issue. However, most research papers were discussing the issue negatively, focusing on lack of patriotism, and stability, while ignoring the privileges these children have, such as developing their personality and language acquisition. The paper has a mixed method of research as the data was collected through face interviews and a survey on …

Crafting Electronic Medical Record Ontology For Interoperability, Esingbemi Princewill Ebietomere, Ukeme Nse, Betty Ukhuegbe Ekuobase, Godspower Osaretin Ekuobase

The African Journal of Information Systems

Clinical information system (CIS) whose core component is the electronic medical record (EMR), is critical to efficient health care delivery. However, patient mobility and CIS heterogeneity have strengthened the interoperability problem of EMRs. Although ontology is a panacea to this problem, creating interoperable EMR ontology is still esoteric. This paper explicates how an interoperable EMR ontology was crafted for a tertiary health facility in Nigeria. The ontology named EMRONT was created using the Noy and McGuiness’ methodology and Protégé. EMRONT has been evaluated for quality using competency questions and OntoQA and subsequently refined for interoperability by manual mapping to both …

Henry M. Rowan College of Engineering Departmental Research

Batteries made of charge carriers from Earth-crust abundant materials (e.g., Na, K, and Mg) have received extensive attention as an alternative to Li-ion batteries for grid storage. However, a lack of understanding of the behavior of these larger ions in the electrode materials hinders the development of electrode structures suitable for these large ions. In this study, we investigate the impact of alkali ions (Li, Na, and K) on the redox chemistry and mechanical deformations of iron phosphate composite cathodes by using electrochemical techniques and in situ digital image correlation. Na-ion and Li-ion intercalation demonstrate a nearly linear correlation between …

Community Roles For Supporting Emerging Education Researchers, Christopher A. F. Hass, Emilie Hancock, Samantha Wilson, Shams El-Adawy, Eleanor C. Sayre

Mathematics Faculty Scholarship

DBER attracts many faculty from other STEM disciplines, and these faculty have little or no specific training in DBER. DBER requires a mastery of quantitative, qualitative, and/or mixed methodologies, and also a nuanced understanding of breadth of topic, research questions, and theoretical frameworks. This interdisciplinarity is particularly challenging for emerging DBER researchers who often switch into DBER with only discipline specific content and research training. As part of a large study about how STEM faculty become involved with DBER, we interviewed a number of emerging DBER faculty about their pathways into DBER. We conducted a thematic analysis of these interviews …

Physics

We present limits on spin-independent dark matter-nucleon interactions using a 10.6 g Si athermal phonon detector with a baseline energy resolution of 𝜎𝐸=3.86±0.04⁢(stat)^+0.19_−0.00⁢(syst)  eV. This exclusion analysis sets the most stringent dark matter-nucleon scattering cross-section limits achieved by a cryogenic detector for dark matter particle masses from 93 to 140  MeV/𝑐2, with a raw exposure of 9.9 g d acquired at an above-ground facility. This work illustrates the scientific potential of detectors with athermal phonon sensors with eV-scale energy resolution for future dark matter searches.

Quantitative Soundscape Analysis To Understand Multidimensional Features, Dylan Charles Wilford, Jennifer L. Miksis-Olds, S. Bruce Martin, Daniel R. Howard, Kim Lowell, Anthony P. Lyons, Michael James Smith

Center for Coastal and Ocean Mapping

A methodology for the analysis of soundscapes was developed in an attempt to facilitate efficient and accurate soundscape comparisons across time and space. The methodology consists of a collection of traditional soundscape metrics, statistical measures, and acoustic indices that were selected to quantify several salient properties of marine soundscapes: amplitude, impulsiveness, periodicity, and uniformity. The metrics were calculated over approximately 30 h of semi-continuous passive acoustic data gathered in seven unique acoustic environments. The resultant metric values were compared to a priori descriptions and cross-examined statistically to determine which combination most effectively captured the characteristics of the representative soundscapes. The …

Infrastructure Deficiency Correlation With Pedestrian/Cyclist Crashes: A Data-Driven Approach, Farbod Tavakkoli Khomeini, Barbara Minsker, Michael Hahler, Janille Smith-Colin, Xinlei Wang

Civil and Environmental Engineering Theses and Dissertations

A model for identifying the impacts of infrastructure deficiency on road traffic safety is needed to help governments prioritize strategic investments to increase public safety. During the 2010-2019 period, U.S. pedestrian and cyclist fatalities rose by 44% and 36%, respectively, and previous studies have shown a positive correlation between pedestrian/cyclist crashes and low-income areas. To our knowledge, this study is the first to investigate further the reasons behind the higher probability of pedestrian and cyclist crashes in low-income areas. The proposed hypothesis is that the higher probability of pedestrian and cyclist crashes in low-income areas correlates with higher infrastructure deficiencies …

A Restrained Beam Sub-Model Assembly (Rbsa) For Progressive Collapse Analysis, Muath Alhumaidi

Civil and Environmental Engineering Theses and Dissertations

The progressive collapse failure mode occurs in buildings when a load-carrying element is lost due to extreme events such as explosions caused by terrorist attacks or vehicular impacts. Guidelines and many researches efforts have been established in order to limit and prevent total collapse of buildings after losing a load-carrying component (e.g., a column). Two famous examples of progressive collapse are the 1968 Ronan Point apartment building kitchen explosion on the 18^th floor and the 1995 Alfred P. Murrah Federal Building bombing in Oklahoma City. Both examples resulted in fatalities and injuries. A small number of these …

Geometrically Complex Planar Heat Exchangers, Derli Dias Do Amaral Junior, Jose Lage

Mechanical Engineering Research Theses and Dissertations

In this study, geometrically complex planar heat exchangers, designed in line with the Constructal Law and operating at steady-state, are investigated numerically. The work is divided into two parts, one focusing on diffusion heat transfer in a rectangular plane and another on conjugate diffusion-convection heat transfer in a circular plane heat exchanger.

In the first part, a heat generating rectangular solid volume made of a low conductivity material is cooled through a small, isothermal side-section of the domain. The diffusion cooling process is improved by distributing within the heat generating material a fixed amount of a high conductivity material. The …

Hepatic Cell Mobilization For Protection Against Ischemic Myocardial Injury, Shu Q. Liu, John B. Troy, Chi Hao Luan, Roger J. Guillory Ii

Michigan Tech Publications, Part 1

The heart is capable of activating protective mechanisms in response to ischemic injury to support myocardial survival and performance. These mechanisms have been recognized primarily in the ischemic heart, involving paracrine signaling processes. Here, we report a distant cardioprotective mechanism involving hepatic cell mobilization to the ischemic myocardium in response to experimental myocardial ischemia–reperfusion (MI-R) injury. A parabiotic mouse model was generated by surgical skin-union of two mice and used to induce bilateral MI-R injury with unilateral hepatectomy, establishing concurrent gain- and loss-of-hepatic cell mobilization conditions. Hepatic cells, identified based on the cell-specific expression of enhanced YFP, were found in …

Havana Impressions: Print Culture And Global Modernity In Plantation Cuba (1790-1860), Asiel Sepulveda

Art History Theses and Dissertations

This dissertation examines the imagined worlds of the Cuban plantation system. It tells a story of print culture in a slave society. The story is based in the city of Havana, capital of Cuba, the great fortified port of the Spanish Empire, and seat of one of the largest plantation economies in the Atlantic World. The dissertation is primary concerned with what I call “Havana Impressions,” printed and mental images of the city that impressed a sense of modernity upon the viewer. These images, I argue, lay bare the struggle to define urban modernity under the cultural regimes of Spanish …

Modified Degradation Process Models And Statistical Methods For Assessing Robustness And Reliability Of Complex Networks, Yuzhou Chen

Statistical Science Theses and Dissertations

In this thesis, we develop a novel stochastic modeling approach based on multiple interdependent topological measures of complex networks. The key engine behind our approach is to evaluate the dynamics of multiple network motifs as descriptors of the underlying network topology. Under a framework of the gamma degradation model, we develop a formal statistical framework for the analysis of reliability and robustness of a single complex network as well as for assessing differences in reliability properties exhibited by two different networks. We validate the proposed methodology with Monte Carlo simulation studies and illustrate the utility of the proposed approach by …

Estimation Of Parameters Of Gamma And Generalized Gamma Distributions Based On Censored Experimental Data, Xiangwen Shang

Statistical Science Theses and Dissertations

In time-to-event data analysis, censoring is one of the unique features that restricts our ability to observe the time-to-events and poses difficulties for statistical analysis. Censoring occurs when the exact time-to-event cannot be observed for some or all observations. In this thesis, we study the parameter estimation methods for a two-parameter gamma distribution and a three-parameter generalized gamma distribution based on different kinds of censored data arising from life-testing experiments.

We first study the parameter estimation of a three-parameter generalized gamma distribution based on left-truncated and right-censored data. It is well known that the maximum likelihood estimates of the parameters …

Quantifying Hydrologic Pathway And Source Connectivity Dynamics In Tile Drainage: Implications For Phosphorus Concentrations, Saeid Nazari, William I. Ford, Kevin W. King

Biosystems and Agricultural Engineering Faculty Publications

Flowpathways and source water connectivity dynamics are widely recognized to affect tile-drainage water quality. In this study, we developed and evaluated a framework that couples event-based hydrograph recession and specific conductance end-member mixing analysis (SC-EMMA) to provide a more robust framework for quantifying both flow pathway dynamics and source connectivity of drainage water in tile-drained landscapes. High-frequency (30-min) flow and conductivity data were collected from an edge-of-field tile main located in northwestern Ohio, and the newly developed framework was applied for data collected in water year 2019. Multiple linear regression (MLR) analysis was used to evaluate the impact of pathway-connectivity …

Evaluating Mine Design Alternatives For Social Risks Using Discrete Choice Analysis, Kwame Awuah-Offei, Sisi Que, Atta Ur Rehman

Mining Engineering Faculty Research & Creative Works

As with other engineering design tasks, mine design involves setting design objectives and constraints (the feasible solution space) and finding the optimal design alternative. Mine engineers often struggle to incorporate the preferences of local community members into their evaluation of mine design alternatives because the mining literature lacks tools to quantify such risks during mine planning. This paper presents an approach to evaluate community acceptance (i.e., community preferences for the alternatives) using discrete choice models and decision-based design during mine planning. Using discrete choice models and a rigorous framework, engineers can estimate the cost of social risks as a function …

Classification Of Explainable Artificial Intelligence Methods Through Their Output Formats, Giulia Vilone, Luca Longo

Articles

Machine and deep learning have proven their utility to generate data-driven models with high accuracy and precision. However, their non-linear, complex structures are often difficult to interpret. Consequently, many scholars have developed a plethora of methods to explain their functioning and the logic of their inferences. This systematic review aimed to organise these methods into a hierarchical classification system that builds upon and extends existing taxonomies by adding a significant dimension—the output formats. The reviewed scientific papers were retrieved by conducting an initial search on Google Scholar with the keywords “explainable artificial intelligence”; “explainable machine learning”; and “interpretable machine learning”. …

Scale-Dependence Of Hematite Nanoparticle Sulfidation, Uma Lad

Earth Sciences Theses and Dissertations

Iron (oxyhydr)oxides are widespread in the environment and have a disproportionate effect on the fate of metal(loid)s in groundwater. Numerous studies demonstrate the effect of iron-sulfur dynamics on contaminant sequestration, and particle size further impacts the reactivity of iron (oxyhydr)oxides, including their capacity for sorption and precipitation. This study examines the role of particle size on the sulfidation of iron (oxyhydr)oxides. Synthetic hematite nanoparticles with approximate diameters of 7.1 nm and 104 nm were coated onto quartz sand and reacted with bisulfide by advective flow.

Characterization of these nanoparticles revealed hydroxyls present at the hematite surface, with large particles having …

Reducing Power During Manufacturing Test Using Different Architectures, Yi Sun

Computer Science and Engineering Theses and Dissertations

Power during manufacturing test can be several times higher than power consumption in functional mode. Excessive power during test can cause IR drop, over-heating, and early aging of the chips. In this dissertation, three different architectures have been introduced to reduce test power in general cases as well as in certain scenarios, including field test.

In the first architecture, scan chains are divided into several segments. Every segment needs a control bit to enable capture in a segment when new faults are detectable on that segment for that pattern. Otherwise, the segment should be disabled to reduce capture power. We …
