Utilizing Atcs Data To Inform A Dynamic Reassignment System For Muni Metro Light Rail Vehicles Departing Embarcadero Station, April M. Hickey

Master's Theses

This is a report of a professional project intended to act as an informational tool for the evaluation of a dynamic dispatch system at Embarcadero Station for the San Francisco Municipal Transportation Agency (SFMTA). Systems that operate dispatch algorithms do so in response to on-time performance and reliability. The optimization problem is documented in many transportation contexts including airline networks, bus dispatch, and freight routing. According to the research, optimizing available options and re-routing based on available options can create a more efficient system that would minimize operating costs and improving service reliability for customers.

The methodology presented here uses …

Reliability Analysis Of Low-Silver Bga Spheres Comparing Failure Detection Criteria, Briana Fredericks

Industrial and Manufacturing Engineering

One of the challenges of solder joint reliability tests is estimating the time of failure of the solder joint. Failure criteria should be able to detect solder joint failure as early as possible, while minimizing the probability of false detection. The failure mechanism under study is cracks due to thermal fatigue. The most common method to estimate failure due to cracks is to monitor the resistance during testing, because solder imaging and cross-sectioning methods are destructive. Current industry failure criteria do not adequately demonstrate the relationship between the size of the crack and the resulting change in resistance. This project …

Determining A Reliability Factor For Photovoltaic's In San Luis Obispo, Ryan S. Roach

Industrial and Manufacturing Engineering

This project will analyze raw photovoltaic (PV) solar panel performance data in order to determine a reliability factor for solar panels in San Luis Obispo. This project is a subset of a larger project being performed by SLO RESCO, which is funded by a grant from the California Energy Commission. Their project will explore the use of solar, wind, geothermal, and biomass renewable resources. The scope of this project is limited to a small section of RESCO's analysis of solar panel technology and implementation in which a reliability factor will be generated.

The objective is to determine a reliability factor …
