Fault Diagnosis And Failure Prognostics Of Lithium-Ion Battery Based On Least Squares Support Vector Machine And Memory Particle Filter Framework, Mohammed Ali Lskaafi Dec 2015

Fault Diagnosis And Failure Prognostics Of Lithium-Ion Battery Based On Least Squares Support Vector Machine And Memory Particle Filter Framework, Mohammed Ali Lskaafi

Doctoral Dissertations

123456A novel data driven approach is developed for fault diagnosis and remaining useful life (RUL) prognostics for lithium-ion batteries using Least Square Support Vector Machine (LS-SVM) and Memory-Particle Filter (M-PF). Unlike traditional data-driven models for capacity fault diagnosis and failure prognosis, which require multidimensional physical characteristics, the proposed algorithm uses only two variables: Energy Efficiency (EE), and Work Temperature. The aim of this novel framework is to improve the accuracy of incipient and abrupt faults diagnosis and failure prognosis. First, the LSSVM is used to generate residual signal based on capacity fade trends of the Li-ion batteries. Second, adaptive threshold …

Integration Of Maintenance Into Design And Sustainability Of Buildings, Dinesh Reddy Patlolla Aug 2015

Integration Of Maintenance Into Design And Sustainability Of Buildings, Dinesh Reddy Patlolla

Masters Theses

Custodial maintenance is an important aspect of operational maintenance in a facility. Custodial maintenance improves an organization's discipline, performance and keeps surroundings healthy. That being said maintaining clean surroundings involves considerable cost. Custodial maintenance cost forms significant portion of building budgets, however these costs are often neglected. This research deals with the identification of variables that affect maintenance costs in a facility and reduction of maintenance costs. The minimization of cost is done by giving the administrator or facilities manager the option of selecting alternatives in frequency of maintenance, level of maintenance and the number of people required to complete …


Assessment Of Management And Documentation Systems For The Bowling Green State University American Society For Quality Student Branch, Sara Murphy Jun 2015

Assessment Of Management And Documentation Systems For The Bowling Green State University American Society For Quality Student Branch, Sara Murphy

Master of Education in Instructional Design and Technology Plan II Graduate Projects

The Bowling Green State University (BGSU) American Society for Quality (ASQ) student branch seeks to provide current and prospective students the opportunity to expand or build upon current and evolving quality principles. This project seeks to provide the ASQ student branch the opportunity to develop documented systems of daily operations and other activities in relation to the defined BGSU ASQ student branch organizational objectives. The research associated with this project will provide detailed information related to the organizational requirements to aid in the development of documented systemic procedures. The information also indicates what practices should be in place to ensure …

Mathematical Modeling For Platform-Based Product Configuration Considering Total Life-Cycle Sustainability, Tian Lan Jan 2015

Mathematical Modeling For Platform-Based Product Configuration Considering Total Life-Cycle Sustainability, Tian Lan

Theses and Dissertations--Mechanical Engineering

Many companies are using platform-based product designs to fulfill the requirements of customers while maintaining low cost. However, research that integrates sustainability into platform-based product design is still limited. Considering sustainability during platform-based design process is a challenge because the total life-cycle from pre-manufacturing, manufacturing and use to post-use stages as well as economic, environmental and societal performance in these stages must be considered. In this research, an approach for quantifying sustainability is introduced and a mathematical model is developed for identifying a more sustainable platform. Data from life-cycle assessment is used to quantify environmental factors; criteria from the Product …
