    • Exploring Deep Learning Techniques for Real-time Graphics 

      Thomas, Manu Mathew (2018-05-10)
      Simulating real-life light in a virtual world is computationally very expensive even in a limited capacity. The quality of images synthesized using computer graphics algorithms for offline rendering used in movies has ...
    • Effective Divisors on Kontsevich Moduli Spaces 

      Bridges, Mercer Truett (2018-05-11)
      We study the cone of effective divisors on Kontsevich's moduli space of genus 0 stable maps to projective space in the case where map is equipped with a marked point on the domain curve, extending previous work of Coskun, ...
    • Broad Learning in Multiple Heterogeneous Domains 

      Lu, Chun-Ta (2018-04-17)
      Recent years have witnessed the flourishing of heterogeneous data from various types of domains. For example, online review sites (like Amazon and Yelp) have access to contextual information of shopping histories of users, ...
    • Scales, Diamond and the Strong Tree Property 

      Du, Jin Yang (2018-08-20)
      In this thesis, I prove two consistency results in set theory. The first concerns GCH, very good and bad scales, and the failure of diamond at the successor of a singular. The second concerns the failure of SCH and arbitrary ...
    • MY-AIR Project: Study on Semantic Location and Activity Recognition Algorithms for iOS Systems 

      Monna, Giovanni Clemente (2018-08-10)
      SLAR (Semantic Location and Activity Recognition) algorithms studied on iOS systems. This thesis provides an algorithm for concurrent detection of semantic location and activity of the user, within a range of nine different ...
    • Detection of Suspicious Users Posting Claims about Cancer on Twitter 

      Piras, Massimo (2018-08-09)
      Due to the massive success of social media, online user-generated content has increased exponentially in the last years. Twitter, as a microblogging platform, allows users to share information about their opinions or ...
    • Limit F-Signature Functions of Diagonal Hypersurfaces 

      Shideler, Samuel Joseph (2018-08-06)
      We study limit F-signature functions for diagonal hypersurfaces. We show that these limits exist, that the limits of the derivatives exist, and that these facts recover a number of previously known results. Finally, we ...
    • A Nonlinear Least Squares Framework for Periodic Grating Identification with a HOPS Implementation 

      Kaplan, Matthew C (2018-08-01)
      This thesis focuses upon the scattering of time-harmonic plane waves by a periodic interface. In particular, we consider an inverse problem which involves reconstruction of the interface when provided with measured scattered ...
    • Reliability Issues among Android Components: Analysis, Testing and Solutions 

      Chiaramida, Vincenzo (2018-08-01)
      Reliability is one of the aspects at the core of every operating system for its impact on the user experience. We explore the current status of the reliability in the interactions among Android applications components, ...
    • Hausdorff Dimension of Kuperberg Minimal Sets 

      Ingebretson, Daniel (2018-07-27)
      In 1994, Kuperberg constructed a smooth flow on a three-manifold with no periodic orbits. It was later shown that a generic Kuperberg flow preserves a codimension one laminar minimal set. We develop new techniques to study ...
    • ETNA: a Virtual Reality Game with Affective Dynamic Difficulty Adjustment based on Skin Conductance 

      Amico, Simone (2018-07-18)
      The video game industry is growing year after year, but one of the main problems that most developers have is how to address the right difficulty of a game to satisfy all the players that have different skills and different ...
    • Robust Prediction Methods for Covariate Shift and Active Learning 

      Liu, Anqi (2018-08-02)
      In real world machine learning applications, it is often not very realistic to assume that the training data distribution aligns with the testing data distribution. A relaxation is to assume the distribution shift only ...
    • Problems in Extremal and Probabilistic Combinatorics 

      Wang, Lujia (2018-08-15)
      We study the following four problems in extremal and probabilistic combinatorics: 1. A sunflower is a collection of distinct sets such that the intersection of any two of them is the same as the common intersection $C$ ...
    • An Algorithmic Approach to Redraw US Gerrymandered District Boundaries by Minimizing Wasted Votes 

      Palmieri, Laura (2018-06-19)
      Partisan gerrymandering consists of redrawing the district boundaries to give electoral advantage to a political party. In 1986, it was declared unconstitutional and justiciable by the US Supreme Court and, since then, ...
    • Regularity and Energy Laws in Hydrodynamic Models of Newtonian Fluids and Collective Behavior 

      Leslie, Trevor M. (2018-06-12)
      We consider several hydrodynamic models of Newtonian fluids and collective behavior, including the Euler and Navier-Stokes equations (both homogeneous and inhomogeneous) as well as the fractional Euler Alignment model. ...
    • Geodesic-based Properties in Complex Networks 

      Mobasheri, Nasim (2018-08-21)
      In the modern age of the Internet, complex large-scale networks are most likely a part of our daily interactions. From social networks like Facebook and Twitter, to technological systems such as World Wide Web and the ...
    • Broad Learning for Healthcare 

      Cao, Bokai (2018-03-27)
      A broad spectrum of data from different modalities are generated in the healthcare domain every day, including scalar data (e.g., clinical measures collected at hospitals), tensor data (e.g., neuroimages analyzed by research ...
    • Rigid Multi-Motion Optical Flow Estimation 

      Gerlich, Tomas (2018-01-12)
      Optical flow is a fundamental problem in computer vision. Given a pair of image frames from a video source, the objective is to estimate the movement, or translation of pixels in the second image with respect to the first ...
    • An Iterative Spectral Approach to Recovering Planted Partitions 

      Cole, Samuel (2018-04-06)
      In the planted partition problem, the n vertices of a random graph are partitioned into k "clusters," and edges between vertices in the same cluster and different clusters are included with constant probability p and q, ...
