  • Network coding for sensor networks, distributed storage and video streaming

    Creator:
    Nguyen, Kien Trung
    Abstract:
    The classical store-and-forward routing has and will continue to be the most important routing architecture in many modern packet-switched communication networks. In a packet-switched network, data is sent in the form of discrete packets that traverse hop-by-hop from a source to a destination. At each intermediate hop, the router stores...

  • Energy Harvesting and Power Management Integrated Circuits for Self-Sustaining Wearables

    Creator:
    Bose, Soumya
    Abstract:
    Harvesting energy from ambient sources can provide power autonomy to energy efficient electronics and sensors. The last decade has seen a multitude of ways to scavenge energy from various sources like solar, thermal, electromagnetic, electrostatic, piezo-electric and many more. Thermal energy from human body heat is ubiquitous and can be...

  • Point-of-care and wearable sensors for non-invasive stress hormone detection with molecularly imprinted techniques

    Creator:
    Yeasmin, Sanjida
    Abstract:
    Rapid and sensitive detection of stress hormones, such as cortisol and dehydroepiandrosterone (DHEA), can benefit the diagnosis of diseases related to adrenal gland disorders, post-traumatic stress disorders, chronic fatigue syndrome, and more. Stress hormones fluctuate in a circadian rhythm, the highest in the early morning and the lowest at night;...

  • Inductors in high-performance silicon radio frequency integrated circuits : analysis, modeling, and design considerations

    Creator:
    Lutz, Richard D., Jr
    Abstract:
    Spiral inductors are a key component of mixed-signal and analog integrated circuits (IC's). Such circuits are often fabricated using silicon-based technology, owing to the inherent low-cost and high volume production aspects. However, semiconducting substrate materials such as silicon can have adverse effects on spiral inductor performance due to the lossy...

  • Team differential games and non-linear signal processing

    Creator:
    Bugnon, Francois J.
    Abstract:
    Team pursuit-evasion games are studied here with one performance index for the team as a unit in competition with one common opponent. Particular structures of team games are discussed after a brief introduction of the two-player differential games. The classical calculus of variations is used to derive the feedback strategies...

  • Wireless Microwave Sensing in Environmental and Biomedical Applications

    Creator:
    Uluer, Ismail Hakki
    Abstract:
    This dissertation studies two different wireless microwave sensing applications in the subjects of environmental monitoring and biomedical devices. The environmental sensing application presents a design of novel wireless sensor node configurations. These nodes are intended to be used specifically in a built environment of railroad track ballast for its health...

  • Performance modeling and analysis of asynchronous pipelines for designers

    Creator:
    Chang, Chih-ming, 1964-
    Abstract:
    Better performance has been one of the main motivations behind the recent resurgence of interest in asynchronous circuits (no matter whether this is always true or not). We are particularly interested in the performance of pipelines since they are used extensively in current digital systems. There exists an algorithm that...

  • CMOS Transducers and Programmable Interface Circuits for Resource-Efficient Sensing Applications

    Creator:
    Sengupta, Shaan
    Abstract:
    Modern sensors are complex systems comprising multiple sub-systems such as transducers, analog and mixed-signal interface circuits, digital processing circuits, and packaging. Over the last few decades, innovations in these sub-systems combined with their increased integration in complementary metal-oxide semiconductor (CMOS) processes have led to the rapid growth in sensors for...

  • On the design, modeling, and testing of ocean wave energy converters

    Creator:
    Bosma, Bret
    Abstract:
    Ocean wave energy converter technology continues to advance and new developers continue to emerge, leading to the need for a general design, modeling, and testing methodology. This work presents a development of the process of taking a wave energy converter from a concept to the prototype stage. A two body...

  • Weak-supervision Time-series Analysis

    Creator:
    You, Zeyu
    Abstract:
    Efficient time-series analysis can impact multiple application domains such as motif discovery in gene analysis or music data, extracting spectro-temporal patterns in acoustic scene analysis, or annotating and classifying electrical bio-signals (such as ECG, EEG, and EMG) for medical applications. Time-series analysis involves a variety of tasks. To predict future...
