#### Morphisms with Only Mild Singular Fibers and Bertini Theorems over Finite Fields

(2016-05-04)

We compute the asymptotic density of non-singular hypersurfaces of bidegree (3, d)
in P^n×P^1 with only mild singular fibers over P^1 over a finite field F_q for n =
1, 2. When n = 1 and char F_q > 2, this asymptotic density ...

#### Merge Times and Hitting Times of Time-inhomogeneous Markov Chains

(2014-06-28)

Concepts of Markov chains mixing, the study of the convergence to stationarity, emerged
three decades ago. Studying times to convergence of Markov chains is crucial as it
ties to many other mathematical areas, such as Markov ...

#### On the Existence of a Winning Strategy in the T(4, 3) Knotter Vs. Unknotter Game

(2013-04-24)

Here we prove that the “Knotter” in the T(4, 3) “Knotter vs. Unknotter Game” has a
winning strategy, provided she goes second.

#### Seasonal Volatility of Corn Futures Prices

(2009)

This paper examines the seasonal patterns evident in the volatility of corn futures
prices. It adds to the high-frequency volatility literature by exploring large price
discontinuities (jumps), and both the continuous and ...

#### An Investigation into the Interdependency of the Volatility of Technology Stocks

(2009-04)

This paper examines the contemporaneous and dynamic relationships between the
volatilities of the technology stocks in the S&P 100 index. Factor analysis and
heterogeneous autoregressive regressions are used to ...

#### A Study of Edge Toric Ideals using Associated Graphs

(2012-04-26)

This thesis studies properties of edge toric ideals and resolutions by analyzing the
associated graphs of algebraic structures. It mainly focused on proving that the repeated
edges in a graph wouldn't change some properties ...

#### Wife's labor supply and marital dissolution: evidence from the NLSY79

(2009-04-15)

In response to the changing family and social structures in the United States, an
accurate understanding of mechanisms and the driving forces of marrital dissolution
is
important in many aspects. For one, the knowledge helps ...

#### Causal Inference and Understanding Causal Structure

(2009)

This thesis aims to show that explicit understanding of possible causal structures
often aids in
inferring the true causes from data. This is done by first understanding that causes
are chains
of counterfactual dependence. ...

#### Statistical Analysis of Simulations of Coarsening Droplets Coating a Hydrophobic Surface

(2010-05-07)

Thin layers of slow-moving, viscous fluid which coat hydrophobic surfaces are shaped
by
the competing forces of disjoining pressure and surface tension. These forces form
the fluid layer into an array of discrete droplets ...

#### A Model of Speculative Attacks and Devaluations in Korea and Indonesia

(2009)

Since the beginning of the Bretton Woods era, currency crises and speculative attacks
have affected the world economy. This paper presents a model, originally derived by
Blanco and Garber, that predicts one-period ahead ...
