  • Extending market potential of blueberries with controlled atmosphere storage

    Creator:
    Boonprasom, Pichaya
    Abstract:
    The goal of this research was to determine if controlled atmosphere (CA) storage could be used to extend the market period of fresh Pacific Northwest blueberries and to evaluate the effects different storage atmospheres have on fruit quality. Furthermore, this research also investigated heat and mass transfer characteristics during cooling...

  • HELM, hierarchical environment for linear modeling

    Creator:
    Brown, Carol E.
    Abstract:
    Several problems relating to linear programming modeling have been identified: (1) model formulation, validation and explanation are difficult and time consuming; (2) models must be frequently updated and debugged; (3) flexibility is needed to specify the model schema for a class of problems as a group; and (4) significant differences...

  • Optimizing spatial and temporal aspects of nature reserve design under economic and ecological objectives

    Creator:
    Nalle, Darek J.
    Abstract:
    Alteration of natural areas in attempts to support increasing human populations has been a crucial yet less publicized contributor to the fall of many of the world's greatest civilizations, since healthy ecosystems can help maintain stable societies and economies. Given this unhappy fact and the ancient relationship between people and...

  • Parallel simplex algorithms and loop spreading

    Creator:
    Wu, Youfeng
    Abstract:
    Parallel solutions for two classes of linear programs are presented. First we parallelized the two-phase revised simplex algorithm and showed that it is possible to get linear improvement in performance. The simplex algorithm is the best known algorithm for solving linear programs, and we claim our result is the best...

  • Coordination for Scalable Multiple Robot Planning Under Temporal Uncertainty

    Creator:
    Marcon dos Santos, Gilberto
    Abstract:
    This dissertation incorporates coalition formation and probabilistic planning towards a domain-independent automated planning solution scalable to multiple heterogeneous robots in complex domains. The first research direction investigates the effectiveness of Task Fusion and introduces heuristics that improve task allocation and result in better quality plans, while requiring lower computational cost...

  • Quorum sensing gene regulation in Pseudomonas aeruginosa

    Creator:
    Gupta, Rashmi
    Abstract:
    Pseudomonas aeruginosa is an opportunistic human pathogen that infects immunocompromised individuals such as those suffering from burns or the genetic disorder cystic fibrosis. This organism utilizes a cell-cell communication mechanism known as quorum sensing (QS) to coordinate virulence gene expression and biofilm formation. It has three interconnected QS systems, namely...

  • Incorporating User Feedback into Machine Learning Systems

    Creator:
    Das, Shubhomoy
    Abstract:
    Although machine learning systems are often effective in real-world applications, there are situations in which they can be even better when provided with some degree of end user feedback. This is especially true when the machine learning system needs to customize itself to the end user's preferences, such as in...

  • Architectures and algorithms for dynamic overlay networks

    Creator:
    Abdelwahab, Sherif
    Abstract:
    Most of today’s Internet of Things (IoT) applications assume that data will be moved offdevices into centralized cloud platforms. While existing IoT systems leverage cloud-based analytics for meaningful data reasoning, the assumption that data should always be moved off the devices is problematic. The amount of data to be moved...

  • Exploring the Validity and Genetic Basis of Frailty

    Creator:
    Wu, Chenkai
    Abstract:
    Frailty is a clinical syndrome characterized by decreased resilience to stressors, resulting from dysregulation across multiple physiological systems. Frailty is prevalent in elders and is associated with a wide range of adverse outcomes including death, disability, hip fracture, and falls. In the absence of a gold standard, there is a...
