Description
The Phoenix CubeSat is a 3U Earth imaging CubeSat which will take infrared (IR) photos of cities in the United Stated to study the Urban Heat Island Effect, (UHI) from low earth orbit (LEO). It has many different components that need to be powered during the life of its mission. The only power source during the mission will be its solar panels. It is difficult to calculate power generation from solar panels by hand because of the different orientations the satellite will be positioned in during orbit; therefore, simulation will be used to produce power generation data. Knowing how much power is generated is integral to balancing the power budget, confirming whether there is enough power for all the components, and knowing whether there will be enough power in the batteries during eclipse. This data will be used to create an optimal design for the Phoenix CubeSat to accomplish its mission.

Description
This study looked at the Women's March's use of social media to communicate their organization's mission. Data was collected from their official Twitter, Instagram and Facebook accounts. Facebook posts were collected manually, Twitter data was collected with a Google Sheets add-on and Instagram was collected by Picodash. All the posts were shifted through multiple times to identify the key narratives of the Women's March. These narratives were then compared to the stated "Unity Principles" of the organization to see if they aligned with what the Women's March attempted to fight for. The five narratives were "everyone should have access to affordable health care," "women should have access to positions of power and be respected," "immigrants should be welcomed within the United States," "society will be stronger if it addresses issues intersectionally," and "everyone should be safe in the world and treated as equals." Analysis showed that each of these narratives reflected the "Unity Principles" in some form. While certain narratives were related to more principles than others, it does not diminish the importance of each message.

Description
Current technology does not allow for the full amount of power produced by solar arrays (PV) on spacecraft to be utilized. The arrays are designed with non-reconfigurable architectures and sent on fifteen to twenty year long missions. They cannot be changed once they are in space, so the arrays are designed for the end of life. Throughout their lifetime, solar arrays can degrade in power producing capabilities anywhere from 20% to 50%. Because there is such a drastic difference in the beginning and end of life power production, and because they cannot be reconfigured, a new design has been found necessary in order to increase power production. Reconfiguration allows the solar arrays to achieve maximum power producing capabilities at both the beginning and end of their lives. With the potential to increase power production by 50%, the reconfiguration design consists of a switching network to be able to utilize any combination of cells. The design for reconfiguration must meet the power requirements of the solar array. This thesis will explore different designs for reconfiguration, as well as possible switches for implementation. It will also review other methods to increase power production, as well as discuss future work in this field.

Description
In this paper, we propose an autonomous throwing and catching system to be developed as a preliminary step towards the refinement of a robotic arm capable of improving strength and motor function in the limb. This will be accomplished by first autonomizing simpler movements, such as throwing a ball. In this system, an autonomous thrower will detect a desired target through the use of image processing. The launch angle and direction necessary to hit the target will then be calculated, followed by the launching of the ball. The smart catcher will then detect the ball as it is in the air, calculate its expected landing location based on its initial trajectory, and adjust its position so that the ball lands in the center of the target. The thrower will then proceed to compare the actual landing position with the position where it expected the ball to land, and adjust its calculations accordingly for the next throw. By utilizing this method of feedback, the throwing arm will be able to automatically correct itself. This means that the thrower will ideally be able to hit the target exactly in the center within a few throws, regardless of any additional uncertainty in the system. This project will focus of the controller and image processing components necessary for the autonomous throwing arm to be able to detect the position of the target at which it will be aiming, and for the smart catcher to be able to detect the position of the projectile and estimate its final landing position by tracking its current trajectory.

Description
This project examines the science of electric field sensing and completes experiments, gathering data to support its utility for various applications. The basic system consists of a transmitter, receiver, and lock-in amplifier. The primary goal of the study was to determine if such a system could detect a human disturbance, due to the capacitance of a human body, and such a thesis was supported. Much different results were obtained when a person disturbed the electric field transmitted by the system than when other types of objects, such as chairs and electronic devices, were placed in the field. In fact, there was a distinct difference between persons of varied sizes as well. This thesis goes through the basic design of the system and the process of experimental design for determining the capabilities of such an electric field sensing system.

Description
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.

Description
In the past ten years, social network services have expanded from a digital method in which the public connects with only their friends and families. Social network services have evolved to a highly-accessible, convenient, cost-effective tool to engage with communities beyond one's frequented social circle on a local, national, and global scale. Many politicians have adapted in order to use social network services to connect directly with their constituents. Politicians have begun to use their profiles on social network services as their own privately owned publicity channel, publishing raw "material" like political opinions or legal advocacy, appearances at events and media like photos, videos or links to maintain transparency and accessibility to their constituencies. The content analysis investigates the use of a social network service (Twitter) by five different Arizonan politicians from different municipal, state and federal offices over the period of six months. All posts on Twitter were recorded, evaluated, and categorized by content into one of seventeen different divisions: Constituent Connection, Correction, Culture, Economy, Education, Environment, Healthcare, Humanitarianism, International, Military, Operational, Personal, Political Activity, Reply to Constituent, Security, Social Issues or Sports. The date, category, content, media type and engagement (replies, retweets, and favorites) were also recorded. Understanding how political figures connect and engage with their constituencies contributes to understanding modern campaigning and modern government; politicians are now finding it imperative to have and maintain a social media presence in order to gain relevance, transparency and accessibility with their constituencies. This study examines how politicians are currently utilizing these micro-blogging sites.

Description
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.

Description
This paper examines the relationship between feminism and social media and evaluates the ability of social media to function as an effective platform for the advancement of feminism's objectives. In the decades before social media became an integral part of culture, the popularity of feminism deteriorated and feminist voices were unsure that it could be revived or popularized again. However, in recent years, women have used social media as a mechanism to communicate and disseminate feminist ideas. The birth of what is called "hashtag feminism" has been a fundamental shift in the way feminism is done and advocated for in modern culture. In light of this dramatic shift in venue for feminist conversations, academic feminists are asking a series of pertinent questions: Is social media good for feminism and the achievement of feminist objectives? What, if anything, has feminism compromised in order to fit into 140 characters or fewer? This paper argues that social media has provided a platform for feminists to share their stories, which has aided in the building of feminist constituencies. This is the most important work of feminism, because it is making society more receptive to feminist principles and ideas, transforming our culture into one that can accept and fight for feminism's objectives. This paper will examine a series of case studies in which social media has hosted feminist conversations. It will analyze the impact of this social media as a venue for feminist narratives and evaluate the use of social media as a feminist platform in the movement to achieve feminism's objectives.
