Streszczenie:

With interoperability issues plaguing emergency responders throughout the country, Cognitive Radio (CR) offers a unique solution to streamline communication between police, Emergency Medical Technicians (EMT), and military officers. Using Software Defined Radio (SDR) technology, a flexible radio platform can be potentially configured using a Cognitive Engine (CE) to transmit and receive many different incompatible radio standards. In this thesis, an interface between a Cognitive Engine and an SDR platform is described which modifies (i.e., configures) the radioâ s operation. The interface

Modifications of large reflector antennas, such that their observing capabilities are enhanced in the range of about 10-500~MHz without affecting operation of the pre-existing higher-frequency systems, are addressed in this dissertation. The major contributions of this dissertation can be divided into two parts: 1) designing new low frequency feeds, and 2) developing new analysis methodologies which, as opposed to traditional techniques, are suitable for analyzing low frequency systems. First, we consider the performance of existing schemes that provide low frequency capability. Then, a new

This thesis describes an experimental investigation into the performance of a radio frequency plasma thruster (RFPT). This type of thruster does not rely on the use of high voltage ion acceleration grids or beam neutralisers which are typically life limiting elements of an electric thruster. The RFPT excites an atomic or molecular gas into a plasma using an external RF antenna. This plasma is contained by a cylindrical dielectric source tube which is open at one end. An axial magnetic field is applied to the plasma using one or more solenoids or a permanent magnet source. The magnetic field is

In the event of a disaster, first responders must rapidly gain situational awareness about the environment in order to plan effective response operations. Unmanned ground vehicles are well suited for this task but often require a strong communication link to a remote ground station to effectively relay information. When considering an obstacle-rich environment, non-line-of-sight conditions and naive navigation strategies can cause substantial degradations in radio link quality. Therefore, this thesis incorporates an unmanned aerial vehicle as a radio repeating node and presents a path plann

In this thesis, we analyze allocation of two separate resources in wireless networks: transmit power and buffer space. Controlled allocation of power can provide good performance for both users and the network. Although centralized mechanisms are possible, distributed power control algorithms are preferable for efficient operation of the network. Viewing distributed power allocation as the collection of rational decisions of each user, we make game theoretic problem formulations, devise distributed algorithms and analyze them.

There has been a recent explosive growth in mobile data consumption. This, in turn, imposes many challenges for mobile services providers and regulators in many aspects. One of these primary challenges is maintaining the radio spectrum to handle the current and upcoming expansion in mobile data traffic. In this regard, a radio spectrum regulatory framework based on secondary spectrum access is proposed as one of the solutions for the next generation wireless networks.

This thesis presents the experimental and theoretical studies of nonthermal and stable atmospheric-pressure glow discharges. With the excitation frequency in the kilohertz range, a uniform and stable glow discharge has been successfully produced in atmospheric helium without the usually indispensable dielectric barrier. For this barrier-free cold atmospheric discharge, there are two discharge events occurring, respectively, in the voltage-rising and the voltage-falling phases, and in general they compete with each other. This distinct feature is illustrated through a detailed fluid simulation.

There have been numerous researchers who, over the years, have explored the relationship between the golden ratio and how it relates to the human perception of beauty. Although the golden proportion is one of the aesthetic characteristics contained in many masterpieces of art and design, it is still largely thought of as little more than an aesthetic guideline, that is, if indeed it is even being considered at all. This thesis asserts that golden proportion and practical geometric knowledge can be used as an extremely effective means of codifying the creative process, inspiring and influencing

Doctor of Philosophy<br>Department of Psychological Sciences<br>Gary L. Brase<br>Operational Sex Ratio (OSR: the ratio of reproductively viable males to females in a given population) has been theorized and studied as a construct that may influence behaviors. The encoding of sex ratio was examined in order to determine whether the cognitive process underlying it is automatic or effortful. Further, the current work examines whether OSR or Adult Sex Ratio (ASR: the ratio of adult males to females) is encoded. The current work involved four experiments; two using frequency tracking methodology an

Mating competition is an important process in sexual selection and can be expressed as complex courtship rituals and agonistic behaviours. The strength of mating competition is likely affected by mate availability. The operational sex ratio, the sex ratio of ready-to-mate individuals, reflects mate availability, and is therefore expected to affect competitive behaviour. This thesis explores the effect of operational sex ratio on competitive mating behaviour in the two-spotted goby ( Gobiusculus flavescens). In a field population of two-spotted gobies at the west coast of Sweden, sex roles swit

<p> Financial statement fraud is so prevalent that the American Institute of Certified Public Accountants (AICPA) and the Securities and Exchange Commission (SEC) both issued guidelines dealing with revenue recognition specifically because the majority of financial statement fraud involves overstating revenue. The specific problem addressed by this study was that although there are analytical procedures used throughout the audit process, only 10% - 12% of detected frauds are found using this method. Research has shown that companies with large differences between reported net income and taxabl

The paper explores the driving forces behind corporate cash holdings by analyzing past literature and extending this research to the behavior of firms after the 2008 recession. I look at the cash to assets and net debt to assets ratios from October 1980 to October 2011 to obtain an understanding of the past and current state of cash holdings. A comprehensive literature review is done on agency costs and transactional motives to give the reader an overview of the costs and benefits of holding cash. This provides the foundation for the precautionary motives for companies today to keep cash as a
