Waddle - Always-Canonical Intermediate Representation, Eric Drew Fritz
Waddle - Always-Canonical Intermediate Representation, Eric Drew Fritz
Theses and Dissertations
Program transformations that are able to rely on the presence of canonical properties of the program undergoing optimization can be written to be more robust and efficient than an equivalent but generalized transformation that also handles non-canonical programs. If a canonical property is required but broken earlier in an earlier transformation, it must be rebuilt (often from scratch). This additional work can be a dominating factor in compilation time when many transformations are applied over large programs. This dissertation introduces a methodology for constructing program transformations so that the program remains in an always-canonical form as the program is mutated, …
Multi-Base Chains For Faster Elliptic Curve Cryptography, Saud Al Musa
Multi-Base Chains For Faster Elliptic Curve Cryptography, Saud Al Musa
Theses and Dissertations
This research addresses a multi-base number system (MBNS) for faster elliptic curve cryptography (ECC). The emphasis is on speeding up the main operation of ECC: scalar multiplication (tP). Mainly, it addresses the two issues of using the MBNS with ECC: deriving optimized formulas and choosing fast methods. To address the first issue, this research studies the optimized formulas (e.g., 3P, 5P) in different elliptic curve coordinate systems over prime and binary fields. For elliptic curves over prime fields, affine Weierstrass, Jacobian Weierstrass, and standard twisted Edwards coordinate systems are reviewed. For binary elliptic curves, affine, Lambda-projective, and twisted mu4-normal coordinate …

Concurrency Analysis In Javascript Programs Using Arrows, Joshua Cochrane
Concurrency Analysis In Javascript Programs Using Arrows, Joshua Cochrane
Theses and Dissertations
Concurrency errors are difficult to detect and correct in asynchronous programs such as those implemented in JavaScript. One reason is that it is often difficult to keep track of which parts of the program may execute in parallel and potentially share resources in unexpected, and perhaps unintended, ways. While programming constructs such as promises can help improve the readability of asynchronous JavaScript programs that were traditionally written using callbacks, there are no static tools to identify asynchronous functions that run in parallel, which may potentially cause concurrency errors.
In this work, we present a solution for implementing JavaScript programs using …
Cost-Effective Load Scheduling For Hybrid Renewable Energy Systems, Avinash Shashikala Rajendra
Cost-Effective Load Scheduling For Hybrid Renewable Energy Systems, Avinash Shashikala Rajendra
Theses and Dissertations
Hybrid renewable energy systems offer great promise for the future. However, some lingering concerns regarding stability and cost efficiency still exist. If a private party installs the system and maintains full control, the party may itself alleviate some of these problems by wisely optimizing the benefits offered by the system. One of the ways to do so is to develop a schedule for their load such that the cost incurred is minimized; this is done by maximally utilizing the renewable sources of energy before using the backup options of more conventional energy sources. Creating such a schedule involves considering several …
Online Social Networks’ Investigations Of Individuals’ Healthy And Unhealthy Lifestyle Behaviors And Social Factors Influencing Them —Three Essays, Mahyar Sharif Vaghefi
Online Social Networks’ Investigations Of Individuals’ Healthy And Unhealthy Lifestyle Behaviors And Social Factors Influencing Them —Three Essays, Mahyar Sharif Vaghefi
Theses and Dissertations
More than half of U.S. adults suffer from one or more chronic diseases, which account for 86% of total U.S. healthcare costs. Major contributors to chronic diseases are unhealthy lifestyle behaviors, which include lack of physical activity, poor nutrition, tobacco use, and drinking too much alcohol. A reduction in the prevalence of health-risk behaviors could improve individuals’ longevity and quality of life and may halt the exponential growth of healthcare costs. Prior studies in the field have acknowledged that a comprehensive understanding of health behaviors requires the examination of individual’ behaviors in supra-dyadic social networks. In recent years, the growth …

by
Bohan Fan
The University of Wisconsin-Milwaukee, 2018
Under the Supervision of Professor Zeyun Yu
With increasingly high resolutions of 3D volumetric medical images being widely used in clinical patient treatments, efficient image compression techniques have become in great demand due to the cost in storage and time for transmission. While various algorithms are available, the conflicts between high compression rate and the downgraded quality of the images can partially be harmonized by using the region of interest (ROI) coding technique. Instead of compressing the entire image, we …
3d Sem Surface Reconstruction From Multi-View Images, Waleedur Rehman
3d Sem Surface Reconstruction From Multi-View Images, Waleedur Rehman
Theses and Dissertations
The scanning electron microscope (SEM), a promising imaging equipment has been used to determine the surface properties such as compositions or geometries of specimens by achieving increased magnification, contrast, and resolution. SEM micro-graphs, however, remain two-dimensional (2D). The knowledge and information about their three-dimensional (3D) surface structures are critical in many real-world applications. Having 3D surfaces from SEM images provides true anatomic shapes of micro-scale samples which allow for quantitative measurements and informative visualization of the systems being investigated. A novel multi-view approach for reconstruction of SEM images is demonstrated in this research project. This thesis focuses on the 3D …
Exact Sampling And Prefix Distributions, Sebastian Oberhoff
Exact Sampling And Prefix Distributions, Sebastian Oberhoff
Theses and Dissertations
This thesis explores some new means to generate random numbers without incurring any numerical
inaccuracies along the way. In the context of continuous distributions this leads to the discussion of
prex distributions { discrete distributions that fully capture a continuous distribution by describing
their initial digits. These are rst studied graphically, then analytically, which also leads to a general
examination of the behavior of the distribution of trailing digits of continuous distributions. Finally,
some slightly novel, related results from the theory of computation are presented.

Quantitative Phenotype Analysis To Identify, Validate And Compare Rat Disease Models, Yiqing Zhao
Theses and Dissertations
Introduction
The laboratory rat has been widely used as an animal model in biomedical research. There are many strains exhibiting a wide variety of phenotypes. Capturing these phenotypes in a centralized database provides researchers with an easy method for choosing the appropriate strains for their studies. Current resources such as NBRP and PhysGen provided some preliminary work in rat phenotype databases. However, there are drawbacks in both projects: (1) small number of animals (6 rats) used by NBRP; (2) NBRP project is a one-time effort for each strain; (3) PhysGen web interface only enables queries within a single study – …

Design And Implementation Of A Domain Specific Language For Deep Learning, Xiao Bing Huang
Theses and Dissertations
\textit {Deep Learning} (DL) has found great success in well-diversified areas such as machine vision, speech recognition, big data analysis, and multimedia understanding recently. However, the existing state-of-the-art DL frameworks, e.g. Caffe2, Theano, TensorFlow, MxNet, Torch7, and CNTK, are programming libraries with fixed user interfaces, internal representations, and execution environments. Modifying the code of DL layers or data structure is very challenging without in-depth understanding of the underlying implementation. The optimization of the code and execution in these tools is often limited and relies on the specific DL computation graph manipulation and scheduling that lack systematic and universal strategies. Furthermore, …
