  • Thermal and Aerodynamic Effects of Surface Roughness Patterns on Additive Manufactured Heat Sinks

    Creator:
    Lundeen, Samuel L.
    Abstract:
    Breakthroughs in heat sink design are now limited by conventional manufacturing techniques which can only produce basic fin shapes with homogenous surface structuring. Additive Manufacturing (AM) is a potential disruptive technology for heat sink design and other convective heat transfer solutions, as surface properties can be directionally varied to maximize...

  • Two-Color Laser Induced Fluorescence Imaging of Fluid Temperature for Free Convection and Vapor Condensation

    Creator:
    McAfee, Rachel
    Abstract:
    The development of a continuous and reliable cooling method for computer chips is an evolving subject requiring continuous research in both computer science and thermal management. Two-color laser induced fluorescence (LIF) provides a non-invasive way to investigate electronics cooling fluid behavior. Dielectric fluids are of particular interest as they allow...

  • Studies on effect of stabilizers, chelators and inherent periodicity on nanoparticle antioxidant activity

    Creator:
    Zhou, Zheng
    Abstract:
    The level of reactive oxygen species (ROS) is tightly regulated in biological systems as overproduction can lead to oxidative stress and result in a number of diseases. Due to its negative effects, antioxidants are studied and used against ROS in medicine, pharmaceuticals and therapeutics. Because of issues with the uptake...

  • Behaviors and strategies in end-users' collaborative programming

    Creator:
    Liu, Zheng
    Abstract:
    Traditionally, research into end-user programming has focused on how to make programming more accessible to end users conducting the programming activities all by themselves. However, few researchers have considered introducing the concept of collaborative programming into the area of end-user programming, and how the programming environments and devices should be...

  • Predicting activity type from accelerometer data

    Creator:
    Zheng, Yonglei
    Abstract:
    The study of physical activity is important in improving people’s health as it can help people understand the relationship between physical activity and health. Accelerometers, due to its small size, low cost, convenience and its ability to provide objective information about the frequency, intensity, and duration of physical activity, has...

  • Estimation of the setup accuracy of a surface image-guided stereotactic positioning system

    Creator:
    Meng, Lu Zheng
    Abstract:
    Purpose: Stereotactic radiation therapy and stereotactic radiosurgery deliver radiation precisely to tumors, using special equipment to position and demobilize patients. The VisionRT system, with its component AlignRT, is a non-invasive stereotactic positioning and tracking system that uses cameras to capture infra-red images of patients, and process these images, to obtain...

  • A low ground bounce CMOS off-chip driver design

    Creator:
    Zheng, Jieyin
    Abstract:
    With the advancement of technology, submicron CMOSonly process is available now for Application Specific Integrated Circuits (ASICs). The high integration leads to the need for high pin counts. However voltage supply and ground bounce due to many output drivers switching at the same time is becoming a major problem. In...

  • Flex-shape convolution and an interactive image segmentation system

    Creator:
    Zhou, Zheng
    Abstract:
    Semantic image segmentation is a relatively difficult task in computer vision. With the advent of deep learning, semantic image segmentation is increasingly of interest for researchers because of the excellent predictions from Convolutional Neural Network (CNN). However, CNNs have proven to struggle with obtaining global context of image due to...

  • Low power high resolution data converter in digital CMOS technology

    Creator:
    Zheng, Zhiliang
    Abstract:
    The advance of digital IC technology has been very fast, as shown by rapid development of DSP, digital communication and digital VLSI. Within electronic signal processing, analog-to-digital conversion is a key function, which converts the analog signal into digital form for further processing. Recently, low-voltage and low-power have become also...
