Multivariate Regression And Variance In Concrete Curing Methods: Strength Prediction With Experiments, Haiyan Sally Xie, Sai Ram Gandla, Owen Shi, Pranshoo Solanki

Faculty Publications – Technology

Because concrete strengths and quality are affected by various factors, multivariate regression models are often used to analyze the differences between predicted and target outputs. However, the variableness of a predicted output and how individual input parameters affect prediction reliabilities are still uncertain in practical applications, especially for the prediction of compressive strengths of concrete. This study aims to develop multivariate models for predicting concrete strengths and providing the variance analysis of prediction results by comparisons with experiment outcomes. First, this paper provides an in-depth examination of established variance analysis methods in the context of commonly used multivariate regression models. …

Nature Of Problem-Solving Skills For 21st Century Stem Learners: What Teachers Need To Know, Paul Nnanyereugo Iwuanyanwu

Journal of STEM Teacher Education

Since the emergence of the fourth industrial revolution which calls for a new model of learning for the twenty-first century learners, it has been argued that the nature of problems that learners must solve in science, technology, engineering and mathematics (STEM) must also be transformed to enable new forms of learning skills that are needed to tackle complex global challenges. However, the question of how best to teach these skills purposefully and explicitly is largely overlooked. STEM education reformers recognize that the lecture method or traditional method of teaching is highly ineffective for teaching twenty-first century competencies and skills that …

Methods: In this study, the IMU sensor is coupled with the Arduino, loaded with …

Reliability Improvement On Feasibility Study For Selection Of Infrastructure Projects Using Data Mining And Machine Learning, Xi Hu

Theses and Dissertations

With the progressive development of infrastructure construction, conventional analytical methods such as correlation index, quantifying factors, and peer review are no longer satisfactory in support for decision-making of implementing an infrastructure project in the age of big data. This study proposes using a mathematical model named Fuzzy-Neural Comprehensive Evaluation Model (FNCEM) to improve the reliability of the feasibility study of infrastructure projects by using data mining and machine learning. Specifically, the data collection on time-series data, including traffic videos (278 Gigabytes) and historical weather data, uses transportation cameras and online searching, respectively. Meanwhile, the researcher sent out a questionnaire for …

Examining Career And Technical Education Practitioner Preparation And Professional Development Needs, Shane Wilson Lange

Theses and Dissertations

This quantitative study was used to investigate Illinois automotive educator professional development needs and to identify the demographic landscape of Illinois secondary and post-secondary automotive teachers. The study should bring a greater understanding of what automotive teachers feel they need to learn in order to continue as successful educators. A modified Borich (1980) needs assessment model was used to identify the perceived importance and ability levels for 32 professional competencies. Mean Weighted Discrepancy Scores (MWDS) were calculated using the importance and ability scores in order to report the professional development need. The administered survey was also utilized to examine their …

Potential For On-Site, Prosecutorial Evidence From Drug Residues Collected On Plasmonic Paper: A Pilot Study For Sers-Psi-Ms, Daniel S. Burr

Theses and Dissertations

Given the potential impact of improvements to on-site drug testing, as well as recent, successful displays of paper spray ionization mass spectrometry (PSI-MS) in this regard, this thesis pilots the implementation of Raman spectroscopy as a compliment to MS for field-based confirmatory drug testing. Surface enhanced Raman scattering (SERS) is utilized for applications to trace detection. Two-tiered analysis of individual drug samples is enabled using triangularly-cut plasmonic papers, from which both SERS and PS-MS analysis may be performed. Several drug compounds, representative of traditional and emerging drug types, are examined by these techniques, both separately and as a fully integrated, …

Big Data And Sensor Network For Construction Material Testing, Yao Shi

Theses and Dissertations

Engineers and contractors need to have a precise understanding of the development progress of concrete strength in the natural environment, which helps to save project time and cost. However, current practice of concrete construction depends on published data, charts and curves from laboratory tests. The data would not show frequently changing environmental conditions in the real world, which can affect concrete quality significantly. The objective of this research is to design a reliable and accurate method to validate test data of the strength developments of concrete specimens in early stages. The approach includes the following tasks: (1) arrange sensors to …

Educators’ Perceptions Of Integrated Stem: A Phenomenological Study, Brian K. Sandall, Darrel L. Sandall, Abram L. J. Walton

Journal of STEM Teacher Education

The study utilized a semistructured interview approach to identify phenomena that are related to integrated STEM education by addressing the question: What are the critical components of an integrated STEM definition and what critical factors are necessary for an integrated STEM definition’s implementation? Thirteen expert practitioners were identified and interviewed. The interviews were transcribed and analyzed for content in three different ways: by person, by interview question, and across all interviews using exploratory data analysis methods. Ten identified phenomena were grouped into two classes: structural implementation phenomena and interpersonal implementation phenomena. The structural implementation phenomena were: subject integration, project-based learning, …

Making Connections: Evaluation Of A Professional Development Program For Teachers Focused On Stem Integration, Judy Lambert, Carmen Cioc, Sorin Cioc, Dawn Sandt

Journal of STEM Teacher Education

This article reports on a 2-year evaluation of a STEM integration professional development (PD) program for 40 math, science, and special education teachers in Grades 5–9 from a large Midwestern public school district. The National Research Council’s framework for integrated STEM education (Honey, Pearson, & Schweingruber, 2014) was used to explain the goals, outcomes, nature and scope, and implementation of the program. Teachers were measured on their growth in STEM content knowledge, technology integration, teaching confidence, pedagogical beliefs, and impact of PD. Increases resulted in all these areas with statistically significant improvements in most of them, particularly in Year 2. …

Developing Pennycress ( Thlaspi Arvense ) As A Biodiesel Feedstock Crop And Plant Model System, Michaela Mcginn

Theses and Dissertations

Thlapsi arvense L. (pennycress) is currently being developed as a profitable oilseed-producing winter annual cover crop with extreme cold tolerance and a rapid life cycle that can be grown on fallow farmland throughout the U.S. Midwest Corn Belt, controlling soil erosion and nutrient runoff while serving as an additional source of income for the American farmer without displacing food crops. The research comprising this dissertation demonstrates that pennycress can serve as a user-friendly model system highly similar to Arabidopsis thaliana, and is well-suited for both laboratory and field experimentation, being readily employable in existing growth facilities. After 10 generations of …

Simulation Of Value Stream Mapping And Discrete Optimization Of Energy Consumption In Modular Construction, Md Mukul Chowdhury

Theses and Dissertations

With the increased practice of modularization and prefabrication, the construction industry gained the benefits of quality management, improved completion time, reduced site disruption and vehicular traffic, and improved overall safety and security. Whereas industrialized construction methods, such as modular and manufactured buildings, have evolved over decades, core techniques used in prefabrication plants vary only slightly from those employed in traditional site-built construction. With a focus on energy and cost efficient modular construction, this research presents the development of a simulation, measurement and optimization system for energy consumption in the manufacturing process of modular construction. The system is based on Lean …
