Description
The purpose of this project was to construct and write code for an Internet-of-Things (IoT) based smart pet feeder to promote owner involvement in the health of their pets through the Internet to combat the high rate of obesity in pets in the United States. To achieve this, a pet feeder was developed to track the weight of the pet as well as how much food the pet eats while allowing the owner to see video of their pet eating, all through the owner's smartphone. In this thesis, current pet feeder strengths and weaknesses were researched, pet owners were surveyed, prototype features were decided upon, physical prototype components were purchased, a physical model of the pet feeder was developed in SolidWorks, a prototype was manufactured, and existing IoT libraries were utilized to develop code.

Description
Millions of pets go missing every year and this project has the purpose of offering a pet GPS tracking solution to aid in this issue. An Arduino microcontroller was combined with a GPS module and GSM module to create the hardware of the device, which was then connected to a mobile application that was developed for the explicit purpose of this project. Amazon Web Services was used to significantly bring down the cost of connecting the hardware to the mobile app. Upon the completion of the project, a prototype pet GPS tracking device and mobile application were developed, and instructions were given so that any user could re-create the same solution for their own purposes.

As the Internet of Things continues to expand, not only must our computing power grow
alongside it, our very approach must evolve. While the recent trend has been to centralize our
computing resources in the cloud, it now looks beneficial to push more computing power
towards the “edge” with so called edge computing, reducing the immense strain on cloud
servers and the latency experienced by IoT devices. A new computing paradigm also brings
new opportunities for innovation, and one such innovation could be the use of FPGAs as edge
servers. In this research project, I learn the design flow for developing OpenCL kernels and
custom FPGA BSPs. Using these tools, I investigate the viability of using FPGAs as standalone
edge computing devices. Concluding that—although the technology is a great fit—the current
necessity of dynamically reprogrammable FPGAs to be closely coupled with a host CPU is
holding them back from this purpose. I propose a modification to the architecture of the Intel
Arria 10 GX that would allow it to be decoupled from its host CPU, allowing it to truly serve as a
viable edge computing solution.

Description
Pollution is an increasing problem around the world, and one of the main forms it takes is air pollution. Air pollution, from oxides and dioxides to particulate matter, continues to contribute to millions of deaths each year, which is more than the next three leading causes of environment-related death combined. Plus, the problem is only growing as industrial plants, factories, and transportation continues to rapidly increase across the globe. Those most affected include less developed countries and individuals with pre-existing respiratory conditions. Although many citizens know about this issue, it is often unclear what times and locations are worst in terms of pollutant concentration as it can vary on the time of day, local activity, and other variable factors. As a result, citizens lack the knowledge and resources to properly combat or avoid air pollution, as well as the data and evidence to support any sort of regulatory change. Many companies and organizations have tried to address this through Air Quality Indexes (AQIs) but are not focused enough to help the everyday citizen, and often fail to include many significant pollutants. Thus, we sought to address this issue in a cost-effective way through creating a network of IoT (Internet of Things) devices and deploying them in a select area of Tempe, Arizona. We utilized Arduino Microprocessors and Wireless Radio Frequency Transceivers to send and receive air pollution data in real time. Then, displayed this data in such a way that it could be released to the public via web or mobile app. Furthermore, the product is cheap enough to be reproduced and sold in bulk as well as scaled and customized to be compatible with dozens of different air quality sensors.

Description
Edge computing is an emerging field that improves upon cloud computing by moving the service from a centralized server to several de-centralized servers that are closer to the end user to decrease the latency, bandwidth, and cost requirements. Field programmable grid array (FPGA) devices are highly reconfigurable and excel in highly parallelized tasks, making them popular in many applications including digital signal processing and cryptography, while also making them a great candidate for edge computation. The purpose of this project was to explore existing board support packages for the Arria 10 GX FPGA and propose a BSP design with multiple partial reconfiguration regions to better support the use of FPGAs in edge computing. In this project, the general OpenCL development flow was studied, OpenCL workflow for Altera/Intel FPGAs was researched, the reference OpenCL BSP was explored to understand the connections between the modules, and a customized BSP with two partial reconfiguration regions was proposed. The existing BSP was explored using the Intel Quartus Prime software suite and the block diagrams for the existing and proposed designs were created using Microsoft Visio.
