  • A genetic algorithm for the vehicle routing problem with heterogeneous vehicles from multiple depots, allowing multiple visits

    Creator:
    Lim, Hyunpae
    Abstract:
    In the thesis, an application of a genetic algorithm (GA) is considered to solve the vehicle routing problem (VRP) which involves heterogeneous vehicles to serve known customer demands from multiple depots achieving the minimum delivery cost, where each customer must be satisfied by one or more visit(s), and each vehicle...

  • Sensor communication network within a desktop computer using the DC powerline

    Creator:
    Bahniuk, Eileen Kei
    Abstract:
    Powerline communication (PLC), is becoming a more commonplace method for data transmission, however it is still a very new medium for data transmission, and international standards for powerline communication are still in the process of being developed and established. PLC can provide a means of simplifying the device connectivity to...

  • Deletions and Insertions of the Symbol 0 and Asymmetric/Unidirectional Error Control Codes for the L₁ Metric

    Creator:
    Alqwaifly, Nawaf
    Abstract:
    This work gives some theory and efficient design of binary block codes capable of controlling the deletions of the symbol “0” (referred to as 0-deletions) and/or the insertions of the symbol “0” (referred to as 0-insertions). This problem of controlling 0-deletions and/or 0-insertions (referred to as symmetric 0-errors) is shown...

  • Essays on determinants of human capital accumulation

    Creator:
    Sherpa, Maya
    Abstract:
    This dissertation is composed of two self-contained essays, which examine two different factors that could affect human capital accumulation in a developing country. Both essays utilize cross-sectional data from the second round (2003/04) of national level household survey from Nepal. In the first essay, I estimate the impact of remittances...

  • Threshold Selection Based on the SNR in Time of Arrival Localization System

    Creator:
    Lyu, Tao
    Abstract:
    Threshold-based time of arrival (TOA) estimation is a technique for high-precision indoor localization. Existing threshold selection methods, such as xed thresh- old and normalized threshold methods, do not consider the signal-to-noise radio (SNR) value at the receiver. This is not desired for high-precision positioning. A proper threshold value depends on...

  • Advances in Modeling Natural Resource Management under Uncertainty : Forest Mortality, Policy Design, and the Value of Information

    Creator:
    Sloggy, Matthew R.
    Abstract:
    Advancing the understanding of natural resource management is an important step in mitigating the effects of human activity on the environment, and ensuring efficient outcomes for many sectors of the economy. As humanity’s role in the natural world becomes better understood, the importance of interdisciplinary modeling has grown in leaps...

  • Quantum and Classical Simulation of Electronic Transport at the Nanoscale

    Creator:
    Gruss, Daniel S.
    Abstract:
    Time-dependent electronic transport is increasingly important to the state-of-the-art device design and fabrication. The development of nanoscale sensing, the harnessing and control of structural fluctuations, and the advancement of next-generation materials all require a treatment of quantum dynamics beyond the level of traditional methods and a more nuanced approach to...

    Kim, Kyoung Cheol
    Abstract:
    For manufacturing and service industries to stay competitive in this rapidly changing, globalized world, one of the most important operations, and one that many businesses struggle to plan and manage efficiently, is material handling. There has been a large amount of research on various vehicle routing problems (VRPs) in recent...

    Creator:
    Cibula, Matthew A.
    Abstract:
    The development and some applications of holographic optical tweezers (HOT) are presented. Our HOT system uses a spatial light modulator (SLM) to control the location and properties of the optical trap. We have developed a method for optimizing the diffraction efficiency of a SLM that can be applied in situ...

  • Bioeconomic Simulation Modeling of Fisheries : Three Essays

    Creator:
    Cusack, Christopher Inju
    Abstract:
    Researchers rely on bioeconomic models to guide research and generate fishery management advice for commercial fisheries. Due partly to a paradigm shift towards ecosystem based fishery management, increasing complexity in the characteristics of the problems has meant that bioeconomic simulation models are becoming more prevalent in the fisheries literature. However...
