Natural Resources Management Framework For Agricultural Irrigation Systems Optimization, Juan Valentin Fernandez
Natural Resources Management Framework For Agricultural Irrigation Systems Optimization, Juan Valentin Fernandez
Open Access Theses & Dissertations
Water scarcity has increased substantially in the last decades in many parts of the world, and it is expected to worsen due to the significant increase in global water withdrawals, intensive population growth, and climate change. Water is easily one of the most essential and invaluable global resources due to its many uses, such as drinking, industrial processes, and irrigation. The agriculture sector is one of the most significant water users globally, accounting for nearly 70% of global freshwater withdrawals. Cities and industries compete with the agriculture sector for water sources, producing alarming levels of stress and pollution in the …
Evaluation And Implementation Of Lean Engineering Principles For Improving A University Rocket Team, Alan Garcia
Evaluation And Implementation Of Lean Engineering Principles For Improving A University Rocket Team, Alan Garcia
Open Access Theses & Dissertations
In the present day, lean is a tool applied to manufacturing industries trying to reduce wasteand non-value-added work to every process during the supply chain. While implementing lean thinking in the industry has been highly effective, it is less common for academic purposes. However, it can also improve performance if the concept is correctly applied. The purpose of this thesis is to show and analyze the application of Lean Engineering thinking and its six principles to the Sun City Summit Rocket Team from the University of Texas at El Paso which competed in the Intercollegiate Rocket Engineering Competition (IREC) Spaceport …
Interoperability In An Electrified Pavement System: A Model-Based Systems Engineering Perspective, Beatriz Irene Soto
Interoperability In An Electrified Pavement System: A Model-Based Systems Engineering Perspective, Beatriz Irene Soto
Open Access Theses & Dissertations
In a 2021 statement provided by The White House, (The White House, 2021), the Biden administration announce the goal for electric vehicles to account for 50% of new vehicle sales in the United States by 2035. In addition, the legislation allocates a budget of $7.5 billion to build out a national network of EV chargers along highway corridors to facilitate long-distance travel and within communities to provide convenient charging where people live, work, and shop. This investment will support the President's goal of building a nationwide network of 500,000 EV chargers to accelerate the adoption of EVs, reduce emissions, improve …
Investigation Into The Economic Viability Of Industry 4.0 Practices In A Small Start-Up Setting: A Case Study, Joseph Lindley
Investigation Into The Economic Viability Of Industry 4.0 Practices In A Small Start-Up Setting: A Case Study, Joseph Lindley
Open Access Theses & Dissertations
Industry 4.0 has been a hot button topic since the first rumouringâ??s of a fourth industrial revolution taking place in the early 2010s. Since that time many companies have attempted to transform their process, procedures, and systems to become streamlined, efficient, and overall, more profitable. An example of this can be seen in companies such as Microsoft and IBM, Mitsubishi and Siemens who have gained a stronger foothold in their respective markets by their efficient implementation of Industry 4.0. Before we can address how small start-up companies can begin to compete with these behemoths, we must address the question; what …
Analyzing The Supply Chain Operation Of A Fast-Food Restaurant Using Simulation Modeling And Developing A Cost Estimation Optimization Model In The Disruption Period, Amit Kumar Saha
Open Access Theses & Dissertations
Supply chain operation performance is a much-discussed topic over the last decade which will lead to optimizing the resources required to provide the necessary level of customer service to a specific segment and improve customer service through increased product availability and reduced order cycle time. During disruption in supply chain, performance parameter changes, and the overall supply chain cost at each stage increases. External factors such as labor shortages, delayed and costly supplies, and decreased demand also contribute to this cost. This thesis work presents a research-focused analysis of a small pizza shop, under circumstances that include the loss of …
Productivity And Quality Evaluation In Assembly Using Collaborative Robots, Carlos F. Manzanares Vega
Productivity And Quality Evaluation In Assembly Using Collaborative Robots, Carlos F. Manzanares Vega
Open Access Theses & Dissertations
In Industry 4.0, various technologies have been applied to achieve automation for traditional manufacturing and practices. For this reason, Smart Manufacturing (SM) environments utilize collaborative robots for process optimization by integrating the Internet of Things (IoT). Cobots are equipped with sensors and/or other devices to be able to transmit data in real-time while performing their tasks. Consequently, such SM implementations improves the decision making and business development, such as supply chain and operations, by sharing real-time data from a plant operational level. The collaborative robots are also designed to safely interact and collaborate with humans to perform tasks and optimize …
Efficient Approaches To Steady State Detection In Multivariate Systems, Honglun Xu
Efficient Approaches To Steady State Detection In Multivariate Systems, Honglun Xu
Open Access Theses & Dissertations
Steady state detection is critically important in many engineering fields such as fault detection and diagnosis, process monitoring and control. However, most of the existing methods are designed for univariate signals. In this dissertation, we proposed an efficient online steady state detection method for multivariate systems through a sequential Bayesian partitioning approach. The signal is modeled by a Bayesian piecewise constant mean and covariance model, and a recursive updating method is developed to calculate the posterior distributions analytically. The duration of the current segment is utilized to test the steady state. Insightful guidance is provided for hyperparameter selection. The effectiveness …
