Image Data Mining For Quality Control Of Nanofiber Reinforced Piezoelectric Nanocomposites Based On Sem Images, Zhonghua Hu
Image Data Mining For Quality Control Of Nanofiber Reinforced Piezoelectric Nanocomposites Based On Sem Images, Zhonghua Hu
Open Access Theses & Dissertations
Recently, portable and wireless nano-scaled devices have been widely used in environmental monitoring, medical implants, defense technology, industrial safety, and personal electronics, such as the nanowire-based gas and chemical sensors and programmable nanowire circuit for nano-processors. There has been an increasing demand for high energy density capacitors that can be engineered for various applications in advanced devices. In it, piezoelectric nanofiber materials play critical role in producing new products. A piezo-ceramic polymer composite contains a polymer of high dielectric strength and high permittivity ceramic inclusions, making it well suited as a high energy density capacitor. Furthermore, the research shows that …
Renewable Energy Systems Optimization Using Monte Carlo Simulation And Evolutionary Algorithms, Nicolas Lopez
Renewable Energy Systems Optimization Using Monte Carlo Simulation And Evolutionary Algorithms, Nicolas Lopez
Open Access Theses & Dissertations
This Dissertation explores the Renewable Energy Integration Problem, and proposes a Genetic Algorithm embedded with a Monte Carlo simulation to solve large instances of the problem that are impractical to solve via full enumeration. The Renewable Energy Integration Problem is defined as finding the optimum set of components to supply the electric demand to a hybrid
microgrid. The components considered are solar panels, wind turbines, diesel generators, electric batteries, connections to the power grid and converters, which can be inverters and/or rectifiers. The methodology developed is explained as well as the combinatorial formulation. In addition, 2 case studies of a …
Healthcare Utilization Awareness And Labor Monitoring Methodology: A Theoretical I.M.S.E. Approach To Risk Minimization And Human Metrics Capturing In The Nursing Workforce, Luis Reyes
Open Access Theses & Dissertations
The healthcare industry is so complex and dynamic that the development of any tool designed to promote positive patient outcomes nearly requires the developer to be an actual healthcare practitioner. Many healthcare tools exists that initially give the perception that there will be no future requirements that may hinder the tools' integrity, but more often than not, the unexpected occurs. The future is one unpredictable element of life that most engineers wish they could capture with optimal precision. I.M.S.E. (Industrial, Manufacturing and Systems Engineering) applications do not assist with fortune telling, but they do assist with creating robust tools designed …
Development Of Post-Pareto Optimality Methods For Multiple Objective Optimization, Juan Valentin Fernandez
Development Of Post-Pareto Optimality Methods For Multiple Objective Optimization, Juan Valentin Fernandez
Open Access Theses & Dissertations
In the past years, multiple objective optimization has been considered, as an important research area since in many real life problems there exists multiple criteria that need to be optimized simultaneously. The use of evolutionary algorithms or metaheuristic methods as solution methodologies lead to a large number of Pareto solutions rather than a single unique optimum. This Pareto-optimal set most of the time tends to be very large and the decision maker now faces the challenge of reducing its size to analyze a feasible number of solutions, thus deciding the best possible solution. In this work, two methods will be …
A Cubesat Communication System Development For Gto Mission, Ashiqur Rahman
A Cubesat Communication System Development For Gto Mission, Ashiqur Rahman
Open Access Theses & Dissertations
Tracking, telemetry and command (TT&C) systems on traditional small satellites have advanced significantly in last few decades. The capabilities, requirements and expectations of the communication system have been increased significantly for the smaller satellites. Small satellites are now performing the tasks near to the bigger satellites which increases the dependency on the communication system in terms of reliability and data management. This Thesis paper will focus on development of the communication system of a 1U cube Satellite named Orbital Factory II (OFII). The satellite will be launched into a geostationary transfer orbit (GTO) onboard a United Launch Alliance (ULA) Atlas …
Supplier Evaluation And Selection In Automotive Industry Using Conditional Probability, Anand Raj
Supplier Evaluation And Selection In Automotive Industry Using Conditional Probability, Anand Raj
Open Access Theses & Dissertations
Supplier evaluation and selection is one very important factor for the success of a company. There are many supplier evaluation and selection tools and software available in the market. But this approach is different from the others. Here a comprehensive list of suppliers selection criteria is selected and they are divided in 3 supplier selection group. This group of criteria is done based on the relationship among them. All the suppliers are evaluated based on these 3 supplier selection group. The supplier with the highest value is selected. The probability associated with that factor is assigned and at the end …
Risk Mitigation In The Supply Chain Caused By Multitple Phase-In And Phase-Out Components Using Simio Simulation, Anabel Renteria Marquez
Risk Mitigation In The Supply Chain Caused By Multitple Phase-In And Phase-Out Components Using Simio Simulation, Anabel Renteria Marquez
Open Access Theses & Dissertations
Manufacturing is constantly changing, adapting to new technologies and making improvements on their products design, while dealing with engineering design changes can represent an improvement or savings to the company it can also end up as a huge risk of disruption in the Supply Chain if there is not a safety phase-in and phase-out components transition because the network became more complex and affected processes needs to be revalidated, here comes the importance to set up an strategy to mitigate any possible risk and maximize total revenue.
A case study for a two tiers level Supply Chain system is evaluated …
