  • smart support management automated reasoning technology for compaq customer service
    Innovative Applications of Artificial Intelligence, 1992
    Co-Authors: Timothy L Acorn, Sherry H Walden
    Abstract:

    Because of the increasingly competitive nature of the computer manufacturing industry, Compaq Computer Corporation has made some trend-setting changes in the way it does business. One of these changes is the extension of Compaq's call-logging system to include a problem-Resolution Component that assists customer support personnel in determining the Resolution to a customer's questions and problems. Recently, Compaq extended its customer service to provide not only dealer support but also direct end user support; it is also accepting ownership of any Compaq customer's problems in a Banyan, Microsoft, Novell, or SCO UNIX operating environment. One of the tools that makes this feat possible is SMART (support management automated reasoning technology). SMART is part of a Compaq strategy to increase the effectiveness of the customer support staff and reduce overall cost to the organization by retaining problem-solving knowledge and making it available to the entire support staff at the point it is needed.

  • The Atacama Cosmology Telescope: Component-separated maps of CMB temperature and the thermal Sunyaev-Zel'dovich effect
    HAL CCSD, 2020
    Co-Authors: Madhavacheril, Mathew S., Hill J. Colin, Næss Sigurd, Addison, Graeme E., Aiola Simone, Baildon Taylor, Battaglia Nicholas, Bean Rachel, Bond J. Richard, Calabrese Erminia
    Abstract:

    Optimal analyses of many signals in the cosmic microwave background (CMB) require map-level extraction of individual Components in the microwave sky, rather than measurements at the power spectrum level alone. To date, nearly all map-level Component separation in CMB analyses has been performed exclusively using satellite data. In this paper, we implement a Component separation method based on the internal linear combination (ILC) approach which we have designed to optimally account for the anisotropic noise (in the 2D Fourier domain) often found in ground-based CMB experiments. Using this method, we combine multi-frequency data from the Planck satellite and the Atacama Cosmology Telescope Polarimeter (ACTPol) to construct the first wide-area, arcminute-Resolution Component-separated maps (covering approximately 2100 sq. deg.) of the CMB temperature anisotropy and the thermal Sunyaev-Zel'dovich (tSZ) effect sourced by the inverse-Compton scattering of CMB photons off hot, ionized gas. Our ILC pipeline allows for explicit deprojection of various contaminating signals, including a modified blackbody approximation of the cosmic infrared background (CIB) spectral energy distribution. The cleaned CMB maps will be a useful resource for CMB lensing reconstruction, kinematic SZ cross-correlations, and primordial non-Gaussianity studies. The tSZ maps will be used to study the pressure profiles of galaxies, groups, and clusters through cross-correlations with halo catalogs, with dust contamination controlled via CIB deprojection. The data products described in this paper will be made available on LAMBDA

  • CSCW - One piece at a time: why video-based communication is better for negotiation and conflict Resolution
    Proceedings of the ACM 2012 conference on Computer Supported Cooperative Work - CSCW '12, 2012
    Co-Authors: Wei Dong
    Abstract:

    We compared the effects of three computer mediated communication (CMC) channels (text, audio, and video) on how people performed an appointment-scheduling task. The task involved a grounding and a conflict Resolution Component. The results showed that video conferencing supported participant dyads in reaching a consensus that had better balanced performance between the dyads only when task difficulty was high and when there were more inherent conflicts in the task. Participants across the three CMC conditions also demonstrated different patterns of conversation dynamics during information exchange and negotiation. Mediation analysis showed that in video-based communication, strategies of exchanging less information at a time predicted higher levels of negotiation, which in turn predicted smaller performance differences in high conflict conditions. The results suggested that the design and use of communication technologies for remote conflict Resolution should promote the strategy of exchanging information in small pieces, which could better support subsequent negotiation and foster a sense of fairness.

  • Analog Beamforming for Active Imaging using Sparse Arrays.
    arXiv: Signal Processing, 2019
    Co-Authors: Robin Rajamaki, Sundeep Prabhakar Chepuri, Visa Koivunen
    Abstract:

    This paper studies analog beamforming in active sensing applications, such as millimeter-wave radar or ultrasound imaging. Analog beamforming architectures employ a single RF-IF chain connected to all array elements via inexpensive phase shifters. This can drastically lower costs compared to fully-digital beamformers having a dedicated RF-IF chain for each sensor. However, controlling only the element phases may lead to elevated side-lobe levels and degraded image quality. We address this issue by image addition, which synthesizes a high Resolution image by adding together several lower Resolution Component images. Image addition also facilitates the use of sparse arrays, which can further reduce array costs. To limit the image acquisition time, we formulate an optimization problem for minimizing the number of Component images, subject to achieving a desired point spread function. We propose a gradient descent algorithm for finding a locally optimal solution to this problem. We also derive an upper bound on the number of Component images needed for achieving the traditional fully-digital beamformer solution.

  • ACSSC - Analog Beamforming For Active Imaging Using Sparse Arrays
    2019 53rd Asilomar Conference on Signals Systems and Computers, 2019
    Co-Authors: Robin Rajamaki, Sundeep Prabhakar Chepuri, Visa Koivunen
    Abstract:

    This paper studies analog beamforming in active sensing applications, such as millimeter-wave radar or ultrasound imaging. Analog beamforming architectures employ a single RF-IF front end connected to all array elements via inexpensive phase shifters. This can drastically lower costs compared to fully-digital beamformers having a dedicated front end for each sensor. However, controlling only the element phases may lead to elevated side-lobe levels and degraded image quality. We address this issue by image addition, which synthesizes a high Resolution image by adding together several lower Resolution Component images. Image addition also facilitates the use of sparse arrays, which can further reduce array costs. To limit the image acquisition time, we formulate an optimization problem for minimizing the number of Component images, subject to achieving a desired point spread function. We then propose a gradient descent algorithm for approximately solving this problem. We also derive an upper bound on the number of Component images needed by the analog beamformer to achieve the conventional digital beamforming solution.1
