  • Toward a Wearable RFID System for Real-Time Activity Recognition Using Radio Patterns
    arXiv.cs.OH Pub Date : 2020-03-08
    Liang Wang; Tao Gu; Xianping Tao; Jian Lu

    Elderly care is one of the many applications supported by real-time activity recognition systems. Traditional approaches use cameras, body sensor networks, or radio patterns from various sources for activity recognition. However, these approaches are limited due to ease-of-use, coverage, or privacy preserving issues. In this paper, we present a novel wearable Radio Frequency Identification (RFID) system

  • The NDE 4.0: Key Challenges, Use Cases, and Adaption
    arXiv.cs.OH Pub Date : 2020-03-05
    Johannes Vrana; Ripudaman Singh

    Historians split recent times into three industrial revolutions: mechanization (steam power), technical (electric power and mass production), and digital (computing and microelectronics). The world of NDE has a parallel: tools to sharpen human senses, wave application to view inside the components, and digital processing and automation. As the industry goes through the fourth revolution powered by

  • Engaging Users through Social Media in Public Libraries
    arXiv.cs.OH Pub Date : 2020-02-25
    Hongbo Zou; Hsuanwei Michelle Chen; Sharmistha Dey

    The participatory library is an emerging concept which refers to the idea that an integrated library system must allow users to take part in core functions of the library rather than engaging on the periphery. To embrace the participatory idea, libraries have employed many technologies, such as social media to help them build participatory services and engage users. To help librarians understand the

  • Predicting Memory Compiler Performance Outputs using Feed-Forward Neural Networks
    arXiv.cs.OH Pub Date : 2020-03-05
    Felix Last; Max Haeberlein; Ulf Schlichtmann

    Typical semiconductor chips include thousands of mostly small memories. As memories contribute an estimated 25% to 40% to the overall power, performance, and area (PPA) of a chip, memories must be designed carefully to meet the system's requirements. Memory arrays are highly uniform and can be described by approximately 10 parameters depending mostly on the complexity of the periphery. Thus, to improve

  • Toward Predicting Success and Failure in CS2: A Mixed-Method Analysis
    arXiv.cs.OH Pub Date : 2020-02-25
    Lucas Layman; Yang Song; Curry Guinn

    Factors driving success and failure in CS1 are the subject of much study but less so for CS2. This paper investigates the transition from CS1 to CS2 in search of leading indicators of success in CS2. Both CS1 and CS2 at the University of North Carolina Wilmington (UNCW) are taught in Python with annual enrollments of 300 and 150 respectively. In this paper, we report on the following research questions:

  • Testability of Reversible Iterative Logic Arrays
    arXiv.cs.OH Pub Date : 2008-05-09
    Avik Chakraborty

    Iterative Logic Arrays (ILAs) are ideal as VLSI sub-systems because of their regular structure and its close resemblance with FPGAs (Field Programmable Gate Arrays). Reversible circuits are of interest in the design of very low power circuits where energy loss implied by high frequency switching is not of much consideration. Reversibility is essential for Quantum Computing. This paper examines the

  • On Orthogonal Projections on the Space of Consistent Pairwise Comparisons Matrices
    arXiv.cs.OH Pub Date : 2020-02-16
    W. W. Koczkodaj; R. Smarzewski; J. Szybowski

    In this study, the orthogonalization process for different inner products is applied to pairwise comparisons. Properties of consistent approximations of a given inconsistent pairwise comparisons matrix are examined. A method of a derivation of a priority vector induced by a pairwise comparison matrix for a given inner product has been introduced. The mathematical elegance of orthogonalization and its

  • On the loss of learning capability inside an arrangement of neural networks
    arXiv.cs.OH Pub Date : 2020-01-09
    Ivan Arraut; Diana Diaz

    We analyze the loss of information and the loss of learning capability inside an arrangement of neural networks. Our method is new and based on the formulation of non-unitary Bogoliubov transformations in order to connect the information between different points of the arrangement. This can be done after expanding the activation function in a Fourier series and then assuming that its information is

  • Particle tracking manifestation of compressible flow and mixing induced by Rayleigh-Taylor instability

    Rayleigh-Taylor-instability induced flow and mixing are of great importance both in nature and engineering scenarios. To capture the underpinning physics, one-way coupled particles are introduced to make a Lagrangian tracking supplement to the discrete Boltzmann simulation. Detailed morphological information of the flow field and thermodynamic nonequilibrium behavior around the interfaces in a two-miscible-fluid

    We introduce a method for non-uniform random number generation based on sampling a physical process in a controlled environment. We demonstrate one proof-of-concept implementation of the method that reduces the error of Monte Carlo integration of a univariate Gaussian by 1068 times while doubling the speed of the Monte Carlo simulation. We show that the supply voltage and temperature of the physical

  • Roof Age Determination for the Automated Site-Selection of Rooftop Solar
    arXiv.cs.OH Pub Date : 2020-01-08
    Chris Heinrich; Michael Laskin; Simas Glinskis; Evert van Nieuwenburg

    Rooftop solar is one of the most promising tools for drawing down greenhouse gas (GHG) emissions and is cost-competitive with fossil fuels in many areas of the world today. One of the most important criteria for determining the suitability of a building for rooftop solar is the current age of its roof. The reason for this is simple -- because rooftop solar installations are long-lived, the roof needs

    Business process modelling languages typically enable the representation of business process models by employing (graphical) symbols. These symbols can vary depending upon the verbosity of the language, the modeling paradigm, the focus of the language, and so on. To make explicit the different constructs and rules employed by a specific language as well as bridge the gap across different languages

    Many public controversies involve the assessment of statements about which we have imperfect information. Without a structured approach, it is quite difficult to develop an approach to reasoning which is not based on ad hoc choices. Forms of logic have been used in the past to try to bring such clarity, but these fail for a variety of reasons. We demonstrate a simple approach to bringing a standardized

    Many policymakers, academics and governments have advocated for exchangeable property rights over information as it presents a market solution to what could be considered a market failure. Particularly in jurisdictions such as Africa, Asia or South America, where weaker legal protections and fleeting regulatory enforcement leaves data subjects vulnerable or exploited regardless of the outcome. We argue
