Description
This thesis conducted an evaluation of the performance and return on investment of a 2 x 6m, simple design greenhouse, as a climate control technology. Specifically, differences in internal microclimate conditions between a greenhouse treatment plot, and sun and shaded control plots were assessed and related to observed differences in crop yields across these plots. Growing conditions and productivity of two crops, tomato and swiss chard, which were grown over summer and winter growing seasons, respectively, were compared. It was found that the greenhouse was associated with improved growth conditions (as measured by the R-Index) for both crops but resulted in higher productivity only for tomatoes. Return on investment and food security impacts from the scaling of greenhouse agriculture were also explored.

Description
As one of the root causes of chronic hunger, it is well-established that food insecurity adversely affects health and economic outcomes of those afflicted (Carmichael et al. 2007; Seligman et al. 2009; Huang, Matta Oshima, and Kim, 2010; Pan et al. 2012; Martinez et al. 2018). More than eleven percent of Americans, uncertain about where their next meal will come from, experienced some degree of food insecurity in 2018 (Coleman-Jensen, 2019). Programs like SNAP and WIC have not only proven to be effective in providing food for households, but they can serve as an example for other countries that struggle to help citizens meet their dietary needs (Gundersen, 2019). non-government entities like food banks and food pantries have played an increasingly important role in addressing food insecurity. While there is a perception that food banks and pantries are only emergency resources, evidence suggests that many individuals regularly rely on private hunger relief organizations for food (Paynter et al., 2011; Kicinski, 2012). Food banks play a crucially important role in distributing food and are uniquely positioned to alleviate hunger. However, these private organizations have been shown, compared to public food assistance programs, to be less effective at specifically addressing the issue of food insecurity (Bazerghi et al., 2016; Loopstra & Tarasuk, 2012; Ratcliffe & McKernan, 2010; Metallinos-Katsaras et al., 2010). Existing research has largely focused on the characteristics of food pantry clients generally, without exploring the socio-economic and experiential variation within this group (Towers, 2009; Kicinski, 2012; Gundersen el al., 2017). This study fills a gap in the literature by examining the characteristics of food pantry users, and how they compare to those not using food pantries but still face food insecurity, using nationally representative survey data. Additionally, I explore whether food pantries and public food assistance programs might be “bundled” together. I focus on gradients of economic vulnerability by examining households who participate in public food assistance programs, are SNAP-eligible but not participating, as well as households who bundle both private and public food assistance to meet their food needs. With this thesis, I hope to contribute this research by providing behavioral insights into understanding the role that food banks play in mitigating challenges associated with food insecurity among US households.

Description
Apple’s HomeKit framework centralizes control of smart home devices and allows users to create home automations based on predefined rules. For example, a user can add a rule to turn off all the lights in their house whenever they leave. Currently, these rules must be added through a graphical user interface provided by Apple or a third-party app on iOS. This thesis describes how a text-based language provides users with a more expressive means of creating complex home automations and successfully implements such a language. Rules created using this text-based format are parsed and interpreted into rules that can be added directly into HomeKit. This thesis also explores how security features should be implemented with this text-based approach. Since automations are run by the system without user interaction, it is important to consider how the system itself can provide functionality to address the unintended consequences that may result from running an automation. This is especially important for the text-based approach since its increase in expressiveness makes it easier for a user to make a mistake in programming that leads to a security concern. The proposed method for preventing unintended side effects is using a simulation to run every automation prior to actually running the automation on real-world devices. This approach allows users to code some conditions that must be satisfied in order for the automation to run on devices in the home. This thesis describes the creation of such a program that successfully simulates every device in the home. There were limitations, however, with Apple's HomeKit framework, which made it impractical to match the state of simulated devices to real devices in the home. Without being able to match the current state of the home to the current state of the simulation, this method cannot satisfy the goal of ensuring that certain adverse effects will not occur as a result of automations. Other smart home control platforms that provide more extensibility could be used to create this simulation-based security approach. Perhaps as Apple continues to open up their HomeKit platform to developers, this approach may be feasible within Apple's ecosystem at some point in the future.

Description
This paper describes the attempt of designing and building a two wheeled platform that is inherently unstable and discovering what tail design is suitable for stabilizing the platform. The platform is a 3D printed box that carries an Arduino, breadboard, MPU6050, a battery and a servo. This box is connected to two continuous servo motors (one on each side) that are attached to wheels, the breadboard and Arduino are mounted on the inside and the MPU6050 is mounted on the back of the base. The MPU6050 collects the data. In the program, that data will be the position of the accelerometer’s x-axis and that data will be sent to the servo motor with the tail for the controls aspect.

Description
Accurate pose initialization and pose estimation are crucial requirements in on-orbit space assembly and various other autonomous on-orbit tasks. However, pose initialization and pose estimation are much more difficult to do accurately and consistently in space. This is primarily due to not only the variable lighting conditions present in space, but also the power requirements mandated by space-flyable hardware. This thesis investigates leveraging a deep learning approach for monocular one-shot pose initialization and pose estimation. A convolutional neural network was used to estimate the 6D pose of an assembly truss object. This network was trained by utilizing synthetic imagery generated from a simulation testbed. Furthermore, techniques to quantify model uncertainty of the deep learning model were investigated and applied in the task of in-space pose estimation and pose initialization. The feasibility of this approach on low-power computational platforms was also tested. The results demonstrate that accurate pose initialization and pose estimation can be conducted using a convolutional neural network. In addition, the results show that the model uncertainty can be obtained from the network. Lastly, the use of deep learning for pose initialization and pose estimation in addition with uncertainty quantification was demonstrated to be feasible on low-power compute platforms.

Description
A significant issue in the medical field is a lack of affordable, rehabilitation practices for patients with drop foot. Drop foot is a condition where a person is unable to lift the front part of the foot. People with this condition usually swing their legs in a wide arc to avoid dragging the toes, or lift their leg higher than normal. This can cause an abnormal walking gait and force them to expend more energy than usual for mobility. This condition is usually the result of a nerve injury, brain or spinal injuries, and muscle disorders. One of the most common causes of drop foot is stroke. While there are ways for stroke survivors to live with drop foot, they do not provide free range of motion. Drop foot braces keep the foot in a stationary position with the foot lifted. They do not allow plantarflexion movement of any sort to mimic foot push off. The purpose of this experiment is to allow stroke survivors with drop foot to adjust to a normal walking gait. This experiment is also meant to allow movement while minimizing metabolic cost for the subject.

Description
This thesis presents a kit of materials intended to present students with a glimpse of what engineering entails by guiding them through building engineering projects similar to what is in the real world. The objective of this project is to pique the interest of children by introducing them to lesser known engineering related topics, and increasing their literacy of terms and methods engineers use to solve problems. The effectiveness of the kit’s content and teaching methods was tested in a classroom of 6th graders and was measured using the responses from surveys handed out. I found that kit did in fact positively lead to a change in the way the students perceived engineering, and it taught students about new engineering related topics. Students were capable of completing difficult tasks of wiring and coding successfully through the use of detailed instruction. However, the instructions were seen in two opposing views of either being too overwhelming or more guidance was necessary.

Description
This paper, titled “Factors of Economic Development and Implications for the Future” focuses on identifying historical factors that have impacted economic development and analyzing what changes may be important for the future. It uses studies done across the world in energy economics, economic development, economic policy, and more to identify important considerations for evaluating historical growth, as well as concerns for the future, particularly given the threat of climate change. Historically important papers, as well as newer insights both feature heavily. This literary review resulted in the finding that education, energy, trade, policy, institutions, endowments, and culture are all important factors for economic development. Endowments and institutions that arise from them are found to be the most important factor in explaining historical development. The paper also analyzes policy that the existing literature suggests could be beneficial for growth. Next, an analysis of factors that the literature identified as important for growth is carried out to assess which countries may have the highest potentials for future growth. The countries are ranked based upon a composite scoring system created from those factors. Countries in Central Asia feature heavily in the top ten entries, while many African countries narrowly miss out on the top ten but still rank relatively high. Together, the findings of both sections are used to discuss how economies have historically developed as well as possible policies to encourage future sustainable development. Both the literature and statistical findings suggest that for future growth promotion of strong institutions that promote property rights and economic growth will be important. They also suggest that coordinated energy policy to increase green technologies and decouple growth from emissions will be essential.

Description
In the last decade, a large variety of algorithms have been developed for use in object tracking, environment mapping, and object classification. It is often difficult for beginners to fully predict the constraints that multirotors place on machine vision algorithms. The purpose of this paper is to explain some of the types of algorithms that can be applied to these aerial systems, why the constraints for these algorithms exist, and what could be done to mitigate them. This paper provides a summary of the processes involved in a popular filter-based tracking algorithm called MOSSE (Minimum Output Sum of Squared Error) and a particular implementation of SLAM (Simultaneous Localization and Mapping) called LSD SLAM.

Description
The relationship between video games and education is something that has been studied extensively in academia. Based upon these studies a new concept was created, gamification. Gamification is the next step in video game research to analyze why video games enhance learning. The interest and research into this concept have developed so much so that it has become its own topic area for research. This study is looking to analyze the effect that gamification has on not only learning, but also self-efficacy. Through a choose your own adventure game, the knowledge and self-efficacy of participants will be examined to observe the differences when learning difficult engineering concepts with and without gamification. It is expected that participants that experienced training through gamification will demonstrate deeper learning and higher self-efficacy than trained through a video. Furthermore, it is anticipated that some video trained participants’ self-efficacy will increase; however, their comprehension will be less than participants trained through gamification. The results of this study can help promote the interest in researching gamification and education, while influencing educators to corporate gamification elements when designing their courses. Moreover, this study continued through adaptation and integration into a statics forces class, investigated if the same results can be found within a classroom setting.
