  • Graph Imitation Learning for Optimal Joint Beamforming and Antenna Selection

    Creator:
    Shrestha, Sagar
    Abstract:
    Transmit beamforming is an important technique employed to improve efficiency and signal quality in wireless communication systems by steering signals towards their in- tended users. It often arises jointly with the antenna selection problem due to various reasons, such as limited number of radio frequency (RF) chains and energy/resource effi-...

  • Large Scale Tensor Decomposition Algorithms Using Block-randomized Stochastic Proximal Gradient

    Creator:
    Gao, Cheng
    Abstract:
    We consider the problem of computing the cannonical polyadic decomposition (CPD) for large-scale dense tensors. This work is a combination of alternating least squares and fiber sampling. Data sparsity can be leveraged to handle large tensor CPD, but this route is not feasible for dense data. Inspired by stochastic optimization's...

  • Clothing evaluative criteria : a comparison between hedonic shoppers and utilitarian shoppers

    Creator:
    Yeh, Chun-Lan
    Abstract:
    According to Engel, Blackwell, and Miniard (1993), evaluative criteria is defined as "the standards and specifications used by consumers to compare different products and brands" (p.51). Many studies have investigated factors that might influence the importance of clothing evaluative criteria used by consumers in the decision making process. However, few...

  • Flexible dual TCP/UDP streaming for H.264 HD video over WLANs

    Creator:
    Zhao, Jing
    Abstract:
    High Definition video streaming over WLANs faces many challenges because video data requires not only data integrity but also frames have strict playout deadline. Traditional streaming methods that rely solely on either UDP or TCP have difficulties meeting both requirements because UDP incurs packet loss while TCP incurs delay. This...

  • A tunable duty-cycle-controlled switched-R-MOSFET-C CMOS filter for low-voltage and high-linearity applications

    Creator:
    Xiao, Ying
    Abstract:
    A novel switched-R-MOSFET-C input branch is proposed for low-voltage and high-linearity applications. The tunability is achieved by varying the clock duty cycle using an automatic tuning circuit. This tuning method does not involve a change in gate voltage, and is therefore particularly suitable for low-voltage applications. The advantages of the...

  • Foreground signature extraction for a non-linear hyperspectral mixing model

    Creator:
    Hollis, Jarrod
    Abstract:
    Hyperspectral images consist of intensity measurements associated with a large number of EM wavelengths per pixel. When a pixel contains a single material, the measurements of the pixel match the spectral signature of the material. When multiple materials are present in a single pixel, spectral mixing occurs, and signatures of...
