Design And Manufacture Of Natural Composite Canoe, Derek Baptista
Industrial and Manufacturing Engineering
Abstract
This report looks into the application and feasibility of manufacturing natural composite canoes. The main fabrics that were analyzed are flax, hemp, and jute. These were then compared to carbon fiber and fiberglass to see the difference in mechanical properties. It was found that the natural fibers have lower mechanical properties but that this could be overcome by designing a balsa wood core with ribs running up the walls. After manufacturing a hemp canoe, many lesson were learned and areas of interest were further explored. With the use of different natural fibers, these canoes can greatly reduce the carbon …

Industrial and Manufacturing Engineering
Absolute Technologies Inc. (ATI) has been growing for years, and is running out of space at their current manufacturing facility in Yorba Linda, CA. ATI will be moving to a much larger facility this winter. They are looking for an efficient way to utilize this space. The machine positions were taken as fixed, seeing as a lean expert was brought in to give advice on placement. With the machines fixed, the scope was narrowed to other areas.
A systematic approach to facilities design is utilized. First, a goal needs to be defined. The goal is to reduce the time wasted …

Industrial and Manufacturing Engineering
A young, growing biomedical company is expanding its warehouse space to keep up with the increasing production. This project’s goals were to recommend a layout and improve a process that would minimize the distance traveled by the material handlers, increase the safety of the warehouse by implementing visual controls, implement ergonomics to reduce chance of injury, and save money for the company. To achieve this first I familiarized myself with their current processes and department and the space required for their current and future production levels. Next I created two alternative layouts, the first (Layout A) to minimize distance and …
Improved Non-Linear Solution Of Dip Coating Flow, Omar Bin Yusuf
Improved Non-Linear Solution Of Dip Coating Flow, Omar Bin Yusuf
Electronic Thesis and Dissertation Repository
A thin layer of film is developed on the surface of a substrate in the dip coating process where the substrate is initially immersed into the coating fluid and then withdrawn continuously from the coating fluid bath. In this study a two dimensional flow of the thin film for a Newtonian fluid is examined theoretically by dividing the film into three separate regions. A general formulation is developed for a thin film flow, which then simplifies for each region upon considering appropriate assumptions to each region. The influence of inertia and surface tension in the presence of gravity is investigated …
A Unified Enterprise-Wide Cost Modeling Framework For Engineering Applications Based On Systems Engineering Principles, Yousuf S. Mohammed
A Unified Enterprise-Wide Cost Modeling Framework For Engineering Applications Based On Systems Engineering Principles, Yousuf S. Mohammed
Mechanical & Aerospace Engineering Theses & Dissertations
In the present research the problem of enterprise-wide cost modeling is approached from a systems engineering standpoint. What this does is to use each stage of product life cycle to obtain useful information that helps in estimating the cost of the system. Once a generic framework is developed for estimating the core cost, layers of other factors that affect the cost are applied to the core cost, such as risk and uncertainty, maintainability, supply-chain and socioeconomic conditions. The cost model is expanded to accommodate a product domain ranging from a simple object to a system in the following hierarchy: System, …

Investigation Into The Usability Of Micromechanical Models To Predict The Behavior Of A Nanocomposite Polymer, Jason Handlogten
All Graduate Theses, Dissertations, and Other Capstone Projects
The purpose of this thesis was to determine the acceptability of a set of existing nanocomposite test specimens for tensile testing and then to determine the Young's and shear modulus of these test specimens. If the test specimens were found to be acceptable, the accuracy of three micromechanical models was to be evaluated by comparing their predictions to the mechanical properties determined from testing the specimens. The set of existing nanocomposite test specimens had a distinct concave shape on two surfaces that were believed to be intended as flat. In order to determine if they adhered to the Type I …
