This dissertation focuses on indoor free-space optical communications systems for use in short range wireless networks. We propose that current radio frequency wireless links be augmented or replaced with optical frequency links due to overcrowding in the radio frequency spectrum. Optical frequencies contain hundreds of terahertz of unregulated bandwidth and...
This paper deals with risk and uncertainties that are an inherent part of
designing and implementing fisheries rebuilding plans. Such risk and
uncertainties stem from a variety of sources, biological, economic and/or
political factors, and are influenced by external factors like changing
environmental conditions. The aim of this paper is...
An increased cross-cultural interaction around the world is
being dictated by the ever increasing communication needs required
by business and national concerns. This increased interaction, and its
resultant inter-dependence, is often referred to as "Globalization."
Due to the effect of globalization on the business and education
environments, this study was...
The application of information theory and digital signal processing techniques to digital
communication has resulted in robust methods for reliable high speed data transmission
over noisy channels environments. Among these methods, multicarrier systems have
become a viable solution for exploiting maximum spectral efficiency over both wideband
highly dispersive static and...
Communication plays an important role in the life
of a couple. This study seeks to determine the nature of
couple communication. This study compares and contrasts
the differences and similarities in communication between
childless couples and parenting couples. The material
for this study comes from interviewing ten married
couples along...
The ability to accurately convey an intended nonverbal emotional message is critical for competent interpersonal functioning. To examine encoding ability, a replication of Noller’s (1980) study employing content standard methodology was conducted. This method is essentially an acting task where participants are given a hypothetical social scene within which they...
Communication is basic to a relationship. What is communication? The word means “to make common.” It is the process of interacting, of creating and negotiating meanings. Your feelings,
communication style, family of origin,gender, and culture all affect your communication.
Rapid advances in wireless networking have led to more mobile phones, PDAs, and other digital mobile devices becoming ubiquitously connected to the Internet. As the demand of delay sensitive real-time applications for these portable devices increases, providing seamless connectivity to wireless networks becomes a critical issue. For this reason, a...
Science is one of the fundamental building blocks of modern societies, and though some science topics are easily accepted by public audiences, others generate intense social controversy by challenging beliefs that are fundamental to a person’s, or group’s, identity. The Theory of Evolution is one of these “hot-button” issues, as...
Impulse-radio ultra-wide-band (IR-UWB) signaling is a promising technique
for high-speed, short-range relay communications networks. Depending on how
the relay node retransmits the signal, there are two main relay schemes: conventional
one-directional (one-way) relay model, and bi-directional (two-way) relay
model. In bi-directional relay communications, wireless network coding (WNC),
also called physical-layer...
