  • “Narco-Deforestation” in Central American Protected Areas: Developing A Spatiotemporal Proxy Database for Drug-Trafficking Activities from Media Reporting

    Creator:
    Cameron, Olivia Z.
    Abstract:
    On a global scale, illicit economies have dramatic impacts on the physical environment. Cocaine trafficking has been recognized as a major driver of deforestation inside Central American protected areas. A key problem in studying and managing the environmental impacts of illicit economic activity is the difficulty in obtaining reliable data....

  • A 90.5dB DR 1MHz BW Hybrid Two Step ADC with CT Incremental and SAR ADCs

    Creator:
    Wang, Yanchao
    Abstract:
    The sensors in real time data processing IoT devices require high resolution and sub-MHz data converters, usually implemented as Incremental ADCs due to the advantages of oversampling technique and low latency. In discrete time incremental (IDT) ADCs, the sampling switch non-linearity, charge injection degrade the resolution, and power hungry OPAMPs...

  • A chopper-stablized CMOS operational amplifier

    Creator:
    Ann, Seung-Han
    Abstract:
    The chopper-stabilized operational amplifier has good low frequency noise properties. Unfortunately a simple technique for simulation of the chopper-stabilized operational amplifier has not been available. This thesis describes the implementation of a differential amplifier using chopper stabilization and its circuit modeling for the SPICE simulation. This circuit has been designed...

  • A Comprehensive Methodology for Measuring the Performance of Transit Networks

    Creator:
    Rahanjam, Mehrdad
    Abstract:
    The performance of transit networks must be measured on a regular basis to understand how well these complex systems fulfill their intended purpose and to identify potential opportunities for improvement. Measuring transit network performance is only achievable by defining a specific set of transit network performance indicators (TNPIs). Different schemes...

  • A computational-based methodology for the rapid determination of initial AP location for WLAN deployment

    Creator:
    Altamirano, Esteban
    Abstract:
    The determination of the optimal location of transceivers is a critical design factor when deploying a wireless local area network (WLAN). The performance of the WLAN will improve in a variety of aspects when the transceivers' locations are adequately determined, including the overall cell coverage to the battery life of...

  • A Fully Integrated Bio-potential Low-noise Amplifier Utilizing Capacitor Multipliers

    Creator:
    Yong, OnnLim
    Abstract:
    In any biomedical signal acquisition system, a front-end amplifier is needed to amplify low amplitude bio-signals while filtering out any unwanted low-frequency artifacts. The design of low frequency poles within the sub-Hz range implies very large time-constants which goes against system integrability. In recent years, the pseudo resistor has been...

  • A high-swing CMOS operational amplifier topology

    Creator:
    Yang, John Jian
    Abstract:
    A circuit topology for high-swing, high-linearity CMOS operational amplifiers has been developed. The technique uses parallel-connected p- and n-channel input pairs to realize an input common-mode voltage range nearly equal to the total power supply voltage. High linearity is achieved by summing the DC bias and AC small-signal currents so...

  • A Metaheuristic Approach for Facilities Location with Balanced Allocation of Customers

    Creator:
    Nippaya, Dheeraporn
    Abstract:
    Organizations are constantly looking for innovative strategies to face more stringent competitive environments and the ever increasing market globalization. An alternative these organizations can pursue to respond to these challenges is to optimize their supply chain network (SCN). Important considerations when optimizing a SCN involve determining locations for plants and...

  • A Quantitative Analysis of Simultaneous Supply and Demand Disruptions on a Multi-Echelon Supply Chain

    Creator:
    Kost, Austin R.
    Abstract:
    Modern supply chains have grown to be far more complex than their predecessors, as global trade and accessibility have opened avenues of trade that were previously impossible. As such, the inherent risk of internal and/or external disruptions impacting the performance of a supply chain has also grown due to the...
