  • Similarity-based real-time concurrency control protocols

    Creator:
    Lai, Chih
    Abstract:
    Serializability is unnecessarily strict for real-time systems because most transactions in such systems occur periodically and changes among data values over a few consecutive periods are often insignificant. Hence, data values produced within a short interval can be treated as if they are "similar" and interchangeable. This notion of similarity...

  • Dependent evidence in reasoning with uncertainty

    Creator:
    Ling, Xiaoning
    Abstract:
    The problem of handling dependent evidence is an important practical issue for applications of reasoning with uncertainty in artificial intelligence. The existing solutions to the problem are not satisfactory because of their ad hoc nature, complexities, or limitations. In this dissertation, we develop a general framework that can be used...

  • Parallel code generation via scheduling

    Creator:
    Meyer-Arendt, Karen
    Abstract:
    A translator has been designed and implemented which generates parallel code for a long instruction word parallel computer with local memories. Its main methods are to translate the sequential source code into single assignment, two-operand form, and to then assign the operations to processors so as to minimize the number...

  • Strengths and weaknesses of Dataparallel C

    Creator:
    S, Seetharamakrishnan
    Abstract:
    Dataparallel C is a SIMD style data-parallel programming language for MIMD com­puters. Dataparallel Chas been implemented on both shared memory (Sequent) and distributed memory (Intel and nCUBE) computers. Here we analyze the strengths and weaknesses of Dataparallel C by comparing the performance of compiled Data­parallel C programs with the performance...

  • Integrating the MVC paradigm into an object-oriented framework to accelerate GUI application development

    Creator:
    Wittel, Walter I., Jr.
    Abstract:
    Applications supporting a graphical user interface (GUI) are difficult to write. While existing tools can accelerate software development, they suffer from a number of problems that limit their helpfulness. They offer too little functionality, and support only a small part of the GUI software development task. They lack architectural models...

  • Algorithms for string matching with applications in molecular biology

    Creator:
    Holloway, James Lee
    Abstract:
    As the volume of genetic sequence data increases due to improved sequencing techniques and increased interest, the computational tools available to analyze the data are becoming inadequate. This thesis seeks to improve a few of the computational methods available to access and analyze data in the genetic sequence databases. The...

  • Task-parallel extension of a data-parallel language

    Creator:
    Macielinski, Damien D.
    Abstract:
    Two prevalent models of parallel programming are data parallelism and task parallelism. Data parallelism is the simultaneous application of a single operation to a data set. This model fits best with regular computations. Task parallelism is the simultaneous application of possibly different operations to possibly different data sets. This fits...

  • EXE, an expert system shell for agricutural applications

    Creator:
    Currans, Kevin
    Abstract:
    This paper discusses the design, construction, and use of a prototype expert system shell, EXE. EXE is non-conventional in that it does not provide a traditional forward or backward chaining inference mechanism. Instead, it allows the domain expert to control the logic flow of the system in a dynamic fashion....

    Creator:
    Chang, Song
    Abstract:
    CREEDA (Crop Rotation Economic and Environmental Impact Decision Aid) is a Windows application for assessing economic and environmental impacts of agricultural activities. In implementing it, we extended the ProCosts database and incorporated the RUSLE (Revised Universal Soil-Loss Equation) application and the SCI (Soil Conditioning Index) application as COM components. ProCosts,...

    Turner, Alexander M.
    Abstract:
    We do not know how to align a very intelligent AI agent's behavior with human interests. I investigate whether—absent a full solution to this AI alignment problem—we can build smart {\ai} agents which have limited impact on the world, and which do not autonomously seek power. In this thesis, I...

  • Imperative Programming with Variational Effects

    Creator:
    Grasley, Alexander B.
    Abstract:
    Variation is a commonly encountered element of modern software systems. Recent research into variation has led to increasing interest in the development of variational programming languages and corresponding variational models of execution. Variational imperative languages pose a particular challenge due to the complex interactions between side effects and variation. The...

    Abstract:
    The Soil Conditioning Index (SCI) aids the conservationist in designing crop rotations and residue management practices when low organic matter, poor soil tilt, and crusting problems are identified. The Natural Resources and Conservation Services (NRCS) field staff and others use the SCI as a qualitative tool during conservation planning. In...

    Abstract:
    Modeling tire-snow interaction is important in designing effective snow tires, which directly affects road safety during wintry weather. Unfortunately, tires have complex tread designs and the physical properties of snow have not been characterized. We employ the Material Point Method (MPM) for simulating a material that mimics the fracturing and...

    Abstract:
    Recent studies have shown that novel continuous dropout methods can be viewed as a Bayesian interpretation of model parameters, though most such studies have shown results using normal distributions. As the posterior distributions over neural network nodes and parameters are intractable, given that they are a result of artificial construction...

  • The Familiarity Hypothesis: Explaining the Behavior of Deep Learning Methods in Out-of-Distribution Detection

    Creator:
    Guyer, Alexander
    Abstract:
    Many object recognition applications require detecting and responding to objects drawn from a different distribution from that of the training data. This task is referred to as out-of-distribution (OOD) detection, and it is often formulated as an outlier detection problem wherein the probability distribution of the known data P(X) is...

    Creator:

    Abstract:
    Distance estimation is a key process for movement and spatial cognition. However, this process is hindered when navigating virtual environments in virtual reality (VR) due to the movement being exclusively visually simulated. In order to contribute to the understanding of how this hinderance effects our ability to estimate distances in...

    The ever-increasing global population presents looming problems for the field of agriculture. Global food demand will, at some point, increase to the point where there is not enough crop-ready land to keep up. This creates an additional incentive, other than economics, for growers to increase their yield-per-acre and make sure...
