This study was designed to discover any relationship between waiting and purchasing impulse goods. I distributed a survey with three conditions: a control with no wait, a wait with information explaining the wait, and a wait with no information. After the wait, participants saw a group of impulse goods and indicated how much they were willing to spend for each item, and how much they desired to buy each item. Results showed that participants in the treatment condition with information for the wait desired the impulse goods the least, and were willing to spend the least to purchase them. However, there was no significant difference between the participants given no information explaining the wait, and the control group in either desire or the price they were willing to pay. This is possibly explained by the apology in the message read by participants in the condition with information. They felt more valued and were less likely to feel the need to spend money on impulse goods that are often purchased to make the participant feel better about their wait.

Pacemakers in the early 1970s were powered by betavoltaic devices which provided long lasting battery life. The betavoltaic devices also emitted gamma radiation due to inadvertent radioisotope contamination, which could not be completely shielded. The betavoltaic devices were quickly replaced by lithium batteries after their invention, and betavoltaics were abandoned.

Pacemakers in the early 1970s were powered by betavoltaic devices which provided long lasting battery life. The betavoltaic devices also emitted gamma radiation due to inadvertent radioisotope contamination, which could not be completely shielded. The betavoltaic devices were quickly replaced by lithium batteries after their invention, and betavoltaics were abandoned. Modern technological advancements made it possible to isolate beta emitting radioisotopes properly and achieve better energy conversion efficiencies which revived the topic of betavoltaics. This research project has studied state-of-the-art pacemakers and modern radioactive power sources in order to determine if modern pacemakers can be safely nuclear powered and if that is a reasonable combination.

Generally, increasing the electrical size of an antenna will increase the directivity of the antenna. In the case of an array of identical antennas with uniform spacing, the electrical size can be increased by increasing the number of elements. However, directivity can be further increased by performing signal processing on the signals received by elements of an antenna array. This thesis focuses primarily on reproducing and expanding upon a method to increase the directivity of a two-element array using non-linear transmission lines periodically loaded with varactor diodes, which act as harmonic multipliers. Simulation and circuit design is performed using Keysight Advanced Design System, a microwave circuit simulation software package. Furthermore, a hardware implementation is discussed and recommendations are made for construction of the hardware array. Finally, possible expansion of the two-element array to a four or more element array is discussed, and preliminary simulations are examined.

A hybrid PV/T module was built, consisting of a thermal liquid heating system and a photovoltaic module system that combine in a hybrid format. This report will discuss the work on the project from Fall 2012 to Spring 2013 and the extended section on the economics for the Honors Thesis. Three stages of experiments were completed. Stage 1 showed our project was functional as we were able to verify our panel produced electricity and increased the temperature of water flowing in the system by 0.65°C. Stage 2 testing included “gluing” the flow system to the back of the panel resulting in an average increase of 4.76°C in the temperature of the water in the system. Stage 3 testing included adding insulating foam to the module which resulted in increasing the average temperature of the water in our flow system by 6.95°C. The economic calculations show the expected energy cost savings for Arizona residents.

In modern remote sensing, arrays of sensors, such as antennas in radio frequency (RF) systems and microphones in acoustic systems, provide a basis for estimating the direction of arrival of a narrow-band signal at the sensor array. A Uniform linear array (ULA) is the most well-studied array geometry in that its performance characteristics and limitations are well known, especially for signals originating in the far field. In some instances, the geometry of an array may be perturbed by an environmental disturbance that actually changes its nominal geometry; such as, towing an array behind a moving vehicle. Additionally, sparse arrays have become of interest again due to recent work in co-prime arrays. These sparse arrays contain fewer elements than a ULA but maintain the array length. The effects of these alterations to a ULA are of interest. Given this motivation, theoretical and experimental (i.e. via computer simulation) processes are used to determine quantitative and qualitative effects of perturbation and sparsification on standard metrics of array performance. These metrics include: main lobe gain, main lobe width and main lobe to side lobe ratio. Furthermore, in order to ascertain results/conclusions, these effects are juxtaposed with the performance of a ULA. Through the perturbation of each element following the first element drawn from a uniform distribution centered around the nominal position, it was found that both the theoretical mean and sample mean are relatively similar to the beam pattern of the full array. Meanwhile, by using a sparsification method of maintaining all the lags, it was found that this particular method was unnecessary. Simply taking out any three elements while maintaining the length of the array will produce similar results. Some configurations of elements give a better performance based on the metrics of interest in comparison to the ULA. These results demonstrate that a sparsified, perturbed or sparsified and perturbed array can be used in place of a Uniform Linear Array depending on the application.

This study focuses on how parents purchase toys for their children. Specifically, the focus is on how likely parents are to purchase a toy typically associated with being feminine, masculine, or gender neutral. This study builds on research that showed that a parent’s gender role ideology affects how likely they are to purchase cross-gender toys (traditionally masculine toys for girls, traditionally feminine toys for boys) for their children (Kollmayer 2018). The study used photographs of pretested toys that had been deemed as masculine, feminine, or gender neutral. Using a within-subjects design, participants saw toys from each category and indicated their likelihood of purchase for each toy. The likelihood of purchase was used as the dependent variable. The findings were used to make recommendations to toy companies and retailers on how to market toys in regards to gender.

Through this thesis we studied and interviewed 6 international business managers that oversee employees in countless countries, and the continents of where they work include: Europe, The Americas, Asia, and Africa. These six managers include: David Kuehn and Ann Marie Griffith from the United States; Bogdan Maliszewski from Poland; Denisa Madarova from the Czech Republic; Gert Schmidts from Germany; and Fer Amkreutz from the Netherlands. Per our interview questions, we discussed how these international managers view their company and culture, the external environment, the cultures they work with and oversee, and the future of international management in regards to a universal value system for business. Our questions were constructed using Hofstede's Cultural Dimensions so that we could better understand how Hofstede's Dimensions have changed due to the technological era, in regards to International Management Styles. In the end, we discovered that there is an undeniable change in how international managers are leading their teams. Throughout the business world, cultural dimensions are changing and are becoming more inclusive of other cultures. This allows managers to lead international teams more effectively and efficiently.

Remotely controlled flying vehicles such as UAVs are becoming more common due to decreases in material costs and increases in performance of components. Radio control link options, however, have not improved at the same rate as airframes, motors, flight controllers, etc [HobbyKing]. Most UAVs require a radio link, often at 2.4 GHz, for flight control, and a second link at 915 MHz for telemetry data transmission [HobbyKing]. Occasionally there is also a video link at either 2.4 GHz or 5.8 GHz. Having multiple transmitters increase power usage from the limited battery reserve that the UAV carries. It also increases weight and space used on the airframe. In addition, the 2.4 GHz band is often congested [ISM Congestion] and does not provide as great a range for a given transmission power as lower frequencies do [Wu]. Attempting to reduce space and weight, power consumption, and simplify design, while increasing control and telemetry range requires the design, testing, and implementation of a radio link that handles both real-time flight control and telemetry with the same transceiver. Only the flight control and telemetry will be addressed in this project. Merging and/or improving the video link will not be tackled at this time in order to simplify project goals to fit inside time constraints. The new radio link system will be verified for functionality then power and range test data will be gathered to determine how effective it is.
