Breast microcalcifications are a potential indicator of cancerous tumors. Current visualization methods are either uncomfortable or impractical. Impedance measurement studies have been performed, but not in a clinical setting due to a low sensitivity and specificity. We are hoping to overcome this challenge with the development of a highly accurate impedance probe on a biopsy needle. With this technique, microcalcifications and the surrounding tissue could be differentiated in an efficient and comfortable manner than current techniques for biopsy procedures. We have developed and tested a functioning prototype for a biopsy needle using bioimpedance sensors to detect microcalcifications in the human body. In the final prototype a waveform generator sends a sin wave at a relatively low frequency(<1KHz) into the pre-amplifier, which both stabilizes and amplifies the signal. A modified howland bridge is then used to achieve a steady AC current through the electrodes. The voltage difference across the electrodes is then used to calculate the impedance being experienced between the electrodes. In our testing, the microcalcifications we are looking for have a noticeably higher impedance than the surrounding breast tissue, this spike in impedance is used to signal the presence of the calcifications, which are then sampled for examination by radiology.

It goes without saying that marriage, and the concept of two people staying together for the rest of their lives, is not easy. In today's society, divorce is something that is becoming more and more prominent among people. However, despite the divorce phenomenon there are still success stories of couples who last and manage to stick together despite the odds. It is difficult to measure the "successfulness" of any marriage due to the fact that so many different elements comprise them. However, there are endless assessments available to be used as tools for attempting measurement of success. A majority of them are related to measuring relationship quality in terms of individual satisfaction by focusing on each individual's happiness within the relationship. Obviously, every marriage is different and there are many things that can impact a couple's' likeliness to stay together such as the general circumstances surrounding their union and each partner's willingness to persevere. For instance, there are a variety of different factors that influence the overall success of marriages within and surrounding the United States Military. Such as physical proximity, frequency of communication, and a mutual desire to make the relationship work. Cultivating a relationship in which one partner is a service member and one partner is a civilian is stressful for both people involved. Specifically, the intense stress couples experience associated with deployment can often cause severe problems such as depression and anxiety that may lead to divorce or mental health problems later on down the road. Stressors specifically related to the deployment cycle can contribute to depression among both service members and their spouses. Most of these families face unique stressors through the course of military service and deployments, including frequent relocations and recon�gurations of the family system, ambiguous loss and fear for a loved one's safety, and high levels of stress and/or dysfunction among family members (Flake, Davis, Johnson, & Middleton, 2009; Huebner, Mancini, Wilcox, Grass, & Grass, 2007) Separation , unpredictable duty hours, and single parenting (parenting while the veteran is away either being deployed or on training courses) are just a few of the stressors that face partners of veterans on a regular basis (Padden, Connors & Agazio, 2011). Dr. John Gottman, the executive director of the Relationship Research Institute. has conducted extensive research regarding marital stability and divorce prediction on thousands of couples over the last forty years of his career. Using video cameras, heart monitors, and other biofeedback equipment, he and his colleagues have screened interviewed and tracked what couples experience during moments of conflict and closeness. Over the span of the last forty years, Dr. Gottman has created a theory he calls "The Four Horsemen of the Apocalypse". In the New Testament, the Four Horsemen of the Apocalypse are a metaphor marking the beginning of end times. Dr. Gottman's Four Horsemen on the other hand, are a metaphor marking the beginning of the demise of a marriage. The horsemen include criticism, contempt, defensiveness, and stonewalling. They are communication styles among couples that Dr. Gottman says can predict the end of a relationship. This notion holds true especially in the implication of military relationships. Focusing on the predictors of divorce, and inspecting the elements of these relationships in which the military is a condition of the union, discoveries can be made as to what makes these military relationships more difficult. An examination through the lens of Dr. Gottman's horsemen of the circumstances surrounding these unions in which deployment physically separates the two partners demonstrates how deployment in and of itself can cause couples to encompass each of the horsemen and eventually push them towards divorce. Throughout the course of this paper, the different elements that embody each of the four horsemen will be examined and analyzed as they pertain to the deployment process. Upon completion of the examination of these different factors, it can be suggested that deployment in its nature becomes the harbinger of the apocalypse. By encompassing all the different aspects of the first four original horsemen, and pushing military couples towards the behaviors that lead in the direction of divorce, deployment in and of itself can be thought of as predecessor, or harbinger of the apocalypse.

In competitive Taekwondo, Electronic Body Protectors (EBPs) are used to register hits made by players during sparring. EBPs are comprised of three main components: chest guard, foot sock, and headgear. This equipment interacts with each other through the use of magnets, electric sensors, transmitters, and a receiver. The receiver is connected to a computer programmed with software to process signals from the transmitter and determine whether or not a competitor scored a point. The current design of EBPs, however, have numerous shortcomings, including sensing false positives, failing to register hits, costing too much, and relying on human judgment. This thesis will thoroughly delineate the operation of the current EBPs used and discuss research performed in order to eliminate these weaknesses.

Batman is one of the most iconic characters in the history of popular culture. Ever since his creation in 1939, the character and his stories have gone through several changes. In my thesis, I explore and analyze the character within the nearly 20-year period in which he went through the most significant changes (1968-1986). Overall, these changes can be summarized as a shift from a lighthearted superhero consistently placed in campy situations to a dark and brooding vigilante who brutally dispatches his enemies. While analyzing the different versions of this character in this period of time, I reference the conclusions of two scholars: Travis Langley and Chuck Tate. Langley wrote a general psychological analysis of Batman by considering the essential characteristics of the character found in all forms of media. Tate concluded that Batman only uses hostile aggression for the sake of deriving pleasure form the pain he causes to criminals. After analyzing the comics as my primary sources, I have concluded that the general findings of Tate and Langley actually ignore the subtle details of changes in the humanity and self-awareness of the character through time. The lighthearted version of Batman in the late 60's is actually a self-obsessed narcissist, but as time passes, the darker mood of the character can be attributed to an increased acknowledgment of the destructive nature of his unique lifestyle. As the character grows more accepting of himself and his own reasons for continuing this lifestyle, his motivations become less self-centered. Overall, the central change of the character throughout time can be traced back to the status of his inner conflict between normal, human desires and the pure desire for constant vengeance.

"The Legal Adventures of Frankie and Rosie" is a creative project that explores the nontraditional format of comics to express creative nonfiction. The project is a set of 30 independent comics that focuses on two primary college-going students who are based off of the authors. The characters, Frankie and Rosie narrate their stories through dialogue. The authors use this narrative model to archive their college experience at ASU. Representing creative nonfiction through comics yields an amalgamated format that can be challenging for both the writers to produce as well as for the readers to consume. Ultimately, the project serves as an attempt to test whether or not the comic medium can stand by itself as an appropriate format to express creative nonfictional narratives without becoming a diluted combination of its purer predecessors.

There are three known materials that readily undergo fission, allowing their use as a base for nuclear fuel: uranium-235, a naturally-occurring but uncommon isotope; plutonium, created from irradiated natural uranium; and uranium-233, produced from thorium.

There are three known materials that readily undergo fission, allowing their use as a base for nuclear fuel: uranium-235, a naturally-occurring but uncommon isotope; plutonium, created from irradiated natural uranium; and uranium-233, produced from thorium. Of the three, uranium-235 and plutonium feature heavily in the modern nuclear industry, while uranium-233 and the thorium fuel cycle have failed to have significant presence in the field. Historically, nuclear energy development in the United States, and thorium development in particular, has been tied to the predominant societal outlook on the field, and thorium was only pursued seriously as an option during a period when nuclear energy was heavily favored, and resources seemed scarce. Recently, thorium-based energy has been experiencing a revival in interest in response to pollution concerns regarding fossil fuels. While public opinion is still wary of uranium, thorium-based designs could reduce reliance on fossil fuels while avoiding traditional drawbacks of nuclear energy. The thorium fuel cycle is more protected against proliferation, but is also much more expensive than the uranium-plutonium cycle in a typical reactor setup. Liquid-fueled molten salt reactor designs, however, bypass the prohibitive expense of U-233 refabrication by avoiding the stage entirely, keeping the chain reaction running with nothing but thorium input required. MSRs can use any fissile material as fuel, and are relatively safe to operate, due to passive features inherent to the design.

Communication between the physical and digital world via software, embedded sensors and network connectivity is referred to by the term, the "Internet of Things" (IoT) [1]. The IoT transforms natural objects into "smart devices" to improve accuracy, reduce human intervention, and provide real-time data [1]. Smart weather stations that upload information, including temperature and humidity, to the Internet are already available. However, these products are often expensive and programmed only for single-purpose use. The LoRa Weather Station is a low cost, low power and low maintenance IoT solution that combines Microchip Technology's LoRa RN2903 module along with Mikroelektronika's Weather Click sensor. This report discusses how the LoRa Weather Station was created, primarily focusing on the LoRa gateway setup by a Raspberry Pi local web server. This project was completed by four electrical engineering students in the EEE 488 and 489 Senior Design courses at Arizona State University from Fall 2016 to Spring 2017. Total expenses for the project were $717.84, including the LoRa gateway which amounted to $104 (see Appendix C for the Bill of Materials).

In this project, an existing waveform generator designed by the vagus nerve stimulation (VNS) technology firm Hoolest Performance Technologies was modified and characterized. Voltage feedback and current feedback systems were designed in order to improve output voltage and current regulation. A wireless communication system was implemented onboard the newly designed waveform generator in order to improve user experience and allow the system to be controlled remotely. Finally, a custom printed circuit board was designed according to the established circuit schematics for the above components, and the layout was miniaturized to a total board footprint area of 1.5 square inches. The completed device was characterized according to several figures of merit including current consumption, voltage and current regulation, and short-circuit behavior.

Captive animals live in extremely controlled environments, within which they are seldom required to forage or hunt for their food, protect their territory from invaders, or generally seek out common resources necessary for survival in the wild. Typically, captive species will exhibit fewer behaviors than their wild counterparts, but this can be remedied through enrichment programs. This study recorded observations of Hamadryas Baboons at the Phoenix Zoo, who exhibited decreased foraging and drinking behaviors as well as an alternative form of social hierarchy. Analysis of these observations suggested further enrichments to encourage the emergence of these behaviors be adopted including an open water source, mobile visual barriers for the exhibit, and providing novel food items which require higher levels of processing.

With the progression of different industries moving away from employing secretaries for business professionals and professors, there exists a void in the area of personal assistance. This problem has existing solutions readily available to replace this service, i.e. secretary or personal assistant, tend to range from expensive and useful to inexpensive and not efficient. This leaves a low cost niche into the market of a virtual office assistant or manager to display messages and to help direct people in obtaining contact information. The development of a low cost solution revolves around the software needed to solve the various problems an accessible and user friendly Virtual Interface in which the owner of the Virtual Office Manager/Assistant can communicate to colleagues who are at standby outside of the owner's office and vice versa. This interface will be allowing the owner to describe the status pertaining to their absence or any other message sent to the interface. For example, the status of the owner's work commute can be described with a simple "Running Late" phrase or a message like "Busy come back in 10 minutes". In addition, any individual with an interest to these entries will have the opportunity to respond back because the device will provide contact information. When idle, the device will show supplemental information such as the owner's calendar and name. The scope of this will be the development and testing of solutions to achieve these goals.
