Time Series Classification Using Covariance Descriptors, Oluwaseun Winsala
Time Series Classification Using Covariance Descriptors, Oluwaseun Winsala
Theses and Dissertations
This thesis presents a novel framework for time series classification that leverages the geometric structure of covariance matrices when labeling signals. Our method maps each signal to a new multivariate localized feature signal (MLFS) representation, from which we compute a covariance descriptor. This robust MLFS covarieance representation handles classification tasks where the sampling rates of the signals vary within a class or classes. We demonstrate that by simply using the k-nearest neighbor classification rule and multiclass kernel support vector machine with the Riemannian metric between the MLFS convariance matrices, which produces state-of-the-art results on a number of standard datasets. Moreover, …

A Systems Engineering Approach For Plant Layout Management & Optimization, Abdulelah Saeed Algarni
Theses and Dissertations
The basis of this paper was to investigate the system engineering applications on petro-chemical facilities layout designs. This work aims to facilitate and introduce the application of Facility Layout Problems to industrial case studies based on system engineering methodologies and performance measurements. Additionally, an effort was made to present a state-of-the-art literature review of industrial layout problems that exhibits scarcity of system engineering role in the design and implementations of industrial Facility Layout Problems. Facility Layout is one of the demanding large-scale optimization problems. Upon the completion of this report, we found a great sense of vitality of system engineering …
Value Based Methodology To Evaluate Sensors For Bridge Structural Health Monitoring Systems, Jefferson Santos De Oliveira
Value Based Methodology To Evaluate Sensors For Bridge Structural Health Monitoring Systems, Jefferson Santos De Oliveira
Theses and Dissertations
Structural health monitoring (SHM) systems have become important tools in the transportation industry to help monitor the behavior and health of civil structures. Today, there is a real concern about the health of bridges because these structures are aging, and various failure events have contributed to increase that concern. Consequently, the topic of improving the effectiveness and appropriate use of SHM systems have become the focus of various government agencies and researchers, both in industry and academia. In this context, this thesis work was developed to understand the general components of bridge SHM systems, and present a methodology to help …
