[ht] does not do anything either.
There is plenty of text in my document, I have omitted it for readability.
Here is the code on its entirety (the block of code in question is at the very end):

\section*{Introduction to the Notes}
These are my personal notes from Northeastern University's course entitled \emph{System Analysis and Control - ME 4555} in the Spring 2010 semester.
Ingeneral they are meant to summarize the content of classroom lectures which will also be supplemented by the text \underline{Control Systems Engineering}, 5th Ed. by
Norman S. Nise.

\section{Introduction}
\subsection{Introduction}
Control systems are all around us. We create control systems and control systems are also an integral part of the human body. A \textbf{Control Systen} consists of subsystems and processes (or \emph{plants}) assembled for the purpose of obtaining a desired \emph{output} with a desired \emph{performance}, given a specified \emph{input}. We build control systems for four primary reasons:
\begin{enumerate}
\item Power amplification
\item Remote control
\item Convenience of input form
\item Compensation for disturances
\end{enumerate}
\subsection{History} For a history, see \emph{Nise}, 4-8.
\subsection{System Configurations}
\textbf{Open-Loop Systems}
\noindent Generally speaking, in an \emph{open-loop system}, there is simply an input, plant and output. That is, the output is merely a function of the input and there is no intent to regulate the output by means of any \emph{looping}. Open-loop systems are generally simple and inexpensive, relatively speaking. That is all we will say on the matter as open-looop systems are not the focus of this course.
\noindent\textbf{Closed-Loop (Feedback Control) Systems}
\noindent Closed-Loop systems on the other hand are designed with the intent of \emph{controlling} or \emph{regulating} output by means of a \emph{controller}.
\subsection{Analysis and Design Objectives}
\emph{Analysis} is the proces by which the sytem's performance is determined. Design parameters such as ransient response and steady-state error are considered. \emph{Design} is a proces by which a system's performance is created or changed.
\subsection{The Design Process}
\textbf{The Six Steps As Described by \emph{Nise}:}
\begin{enumerate}
\item \textbf{Transform Requirements Into a Physical System} - using
requirements, design specifications, such as the desired tarnsient
response and steady-state accuracy are determined.
\item \textbf{Draw a Functional Block Diagram} - the designer now
translates the qualitative description of the system into a functional
block diagram that describes the component parts of the system.
\item \textbf{Create a Schematic}
\item \textbf{Develop a Mathematical Model (Block Diagram)} - after the
schematic is drawn, physical laws such as \emph{{Kirchhoff's voltage
law}}, \textbf{\emph{Kirchhoff's current law}} and \textbf{\emph{Newton's
Laws of motion}} are used to describe the relationship between the input
and output of dynamic systems.
\item \textbf{Reduce The Block Diagram}
\item \textbf{Analyze and Design}
\end{enumerate}
