Improvements To The Predictive Capability Of Fcm Fuel Performance Modeling, Daniel Philip Schappel
Improvements To The Predictive Capability Of Fcm Fuel Performance Modeling, Daniel Philip Schappel
Doctoral Dissertations
A proposed fuel type for improved accident performance in LWRs (Light Water Reactors) involves TRISO (Tristructural-Isotropic) particles embedded in a NITE (Nano Infiltrated Eutectic) silicon carbide matrix. TRISO fuel particles contain a spherical fuel kernel of about 500 to in excess of 800 microns in diameter. The kernel and buffer layer are then coated with three isotropic layers consisting of a dense inner pyrolytic carbon (IPyC), a silicon carbide (SiC) layer, and an outer pyrolytic carbon (OPyC) layer. These layers are about 40 microns thick. The TRISO particle packing fraction in the NITE-SiC matrix is expected to be about 40 …

Mechanical Engineering
Originating from QL+'s customer requirements, the main technical specifications were to have 80% physiological range of motion, elastic energy return, impact absorption, and no external power sources. Based on the background research conducted and the discussions with experts in the field, the project team decided to focus on designing a prosthetic that focused on plantarflexion and dorsiflexion for a more comfortable gait. The main components of the final design are a hydraulic shock absorber, cam, torsion springs, heel, stopper, and separated keel. The heel, front and back keels, and stopper were manufactured out of carbon fiber. The link, lever, attachment …
An Analysis Of The Benefits In Estimating At Different Pipe Union Labor Rates, A.J. Chamorro
An Analysis Of The Benefits In Estimating At Different Pipe Union Labor Rates, A.J. Chamorro
Construction Management
This paper is an analysis of the costs and benefits of estimating at different union labor rates, based on the location of the project and which jurisdiction the project falls in. The basis of the research is a case study of a Bay Area mechanical contractor (Contractor X) which previously estimated at a single labor rate, and recently developed variable estimating. Through that case study, best practices are developed for union pipe trade estimating. The results of the case study show that estimating protocol should be determined on a project by project basis, and company resources and manpower have to …

Weaver Industries in Akron, Ohio provided us with our senior design project. Weaver Industries seeks individuals with disabilities and provides them with job opportunities. One of their products is a “Kong” dog toy. As of now, the instruction pamphlet that comes with this dog toy is placed into each piece of packaging individually by hand. We are tasked with automating this process. Two years ago, a group of students worked on this project, but the reliability of their prototype was only around 60-70%. Then last year, another group of students worked on this project, but again, the reliability of their …
