  • An Overview of Multivariate Regression Analysis of Biological Data

    Creator:
    DeHart, Christopher M.
    Abstract:
    This study investigates methods of multivariate regression analysis and their applications to biological data. It provides an overview of methods of reduced rank regression and sparse multivariate regression, including their motivations, methods, and applications. It also implements a form of sparse regression known as Regularized Multivariate Regression for Identifying Master...

  • Pacific Northwest rangeland carbon sequestration

    Creator:
    Wiggins, Seth T.
    Abstract:
    This paper models the supply curve of carbon sequestration on Pacific Northwest rangelands. Rangeland managers have the ability to sequester carbon in agricultural soils by implementing alternative management practices on their farms. Their low adoption rate in practice suggests a high opportunity cost associated with their implementation. To increase their...

  • Impact of Climate and Disturbance on the Formation of Earlywood and Latewood in Douglas-fir at the Salal Fields Study Site

    Creator:
    Gourley, Derek M. F.
    Abstract:
    Wood density is controlled to a large extent by the relative widths of earlywood and latewood in the stem, but the mechanisms controlling these amounts are poorly understood in coastal Douglas-fir. To understand the role of climatic factors, one hundred and thirty-six increment cores were collected and measured from the...

  • Positive graphical lasso estimation of sparse inverse covariance matrices

    Creator:
    Logan, Paul
    Abstract:
    We explore the possibility of estimating sparse inverse covariance matrices when for scientific reasons the covariance matrix is restricted to be a non-negative matrix. The process mirrors the graphical lasso process developed by Friedman and others(2008) that did not have this additional constraint.Accordingly, the Lasso procedure is done through coordinate...

  • Music Generation and Evaluation Using R

    Creator:
    Lanz, Andrea L.
    Abstract:
    The main goal of this project is to implement an algorithmic music composition procedure and present all procedures and results in a reproducible fashion by creating a web application produced by R. To approach the implementation of the algorithmic composition of music, we start by exploring various models, but ultimately...

  • Prenatal and Early-life Metals Exposure and Immune Function in Children

    Creator:
    Welch, Barrett M.
    Abstract:
    Immune system development during prenatal and early-life periods are essential for healthy development. Environmental and nutritional factors during these periods have strong influences on immune development and can have impacts on disease susceptibility for an individual throughout adulthood. Globally, hundreds of millions of people experience elevated environmental exposure to arsenic,...

  • Nutrient Profile and Nursery Feeding Damage of Halyomorpha halys (Hempitera: Pentatomidae)

    Creator:
    Skillman, Victoria P.
    Abstract:
    Halyomorpha halys Stål, brown marmorated stink bug or BMSB, is now present in 43 US states. A native of eastern Asia, this pest can feed on ~200 different plant species damaging bark, leaves, buds, stems, and fruits. Many of these plant species include wild plants, ornamentals, and agricultural crops. BMSB...

  • Turbine Induced Bird and Bat Fatalities at Wind Projects : Statistical Methods for Mortality Estimation Using Road and Pad Carcass Surveys

    Creator:
    Maurer, Joseph D.
    Abstract:
    Turbines at wind projects pose a threat to birds and bats flying at altitudes within the rotor swept area. These animals die from colliding with the turbine blades. Estimating mortality, or the total number of bird or bat fatalities at a wind project, is critical to understanding environmental impacts of...

  • Modeling and analyzing processes with infrequent failures : implications for process monitoring policies

    Creator:
    Darabi, Shooka
    Abstract:
    Continues improvement of industrial systems require constant measuring process variation and eliminating extraneous variation whenever possible to push the target measures as close to the ideal value as possible. Statistical Processes Control (SPC) technique is a very efficient statistical technique for monitoring and controlling processes variation. In recent years an...

  • Bi-criteria Scheduling in an Assembly Flow Shop with Limited Buffer Storage and Shift Production

    Creator:
    Aryal, Ayush R.
    Abstract:
    In this research, the comparative performance of permutation and non-permutation schedules is investigated in an assembly flow shop (AFS) with shift production, where a limited buffer storage is available between two machines. Most of the traditional scheduling problems consider continuous production, i.e., production occurs for 24 hours (3 * 8-hour...
