Netcon: Dynamic Resource Allocation To Containers Running On Network Switching Appliances, Siena Hanna, Justin Lee, Tania Pham Jun 2022

Netcon: Dynamic Resource Allocation To Containers Running On Network Switching Appliances, Siena Hanna, Justin Lee, Tania Pham

Computer Science and Engineering Senior Theses

A WiFi Access Point (AP) is an important technology that switches data packets to transmit and receive wireless signals to create WiFi. These Access Points (AP) can have powerful processors, but they are idle most of the time [1]. Instead, these idle processing resources could be redirected to run containers for low-latency applications. However, it is essential to ensure that the AP does not suffer performance issues as a result of running containers. The main function of APs is to switch packets, and this function must be preserved while containers are running. In this thesis, we propose a method, NetCon, …

Enhancing The Quality Of Service And Energy Efficiency Of Wifi-Based Iot Networks, Jaykumar Sheth Jun 2022

Enhancing The Quality Of Service And Energy Efficiency Of Wifi-Based Iot Networks, Jaykumar Sheth

Engineering Ph.D. Theses

The 802.11 standard, known as WiFi, is currently being used for a wide variety of applications including Internet of Things (IoT). However, the contention between the traffic of IoT stations (STAs) as well as the contention between these flows and regular user-generated traffic reduces the energy efficiency and timeliness of IoT communication. To remedy this problem, in this thesis, we take the following approaches for mitigating the challenges faced by WiFi-based IoT networks: First, we highlight the importance of observability with respect to WiFi networks and how it helps the researchers to better examine the dynamics of issues and its …

Sengasafe, Patrick Zhang, Matthew Hall, Matthew Brunkhorst

Computer Science and Engineering Senior Theses

There is a lack of effective education about sexual health for women in rural Uganda. Compared to the rest of the world, Uganda has a very high incidence rate of cervical cancer. This is much higher than it should be because it is well established that the human papillomavirus (HPV) is the primary cause of cervical cancer, and vaccinations for HPV have been available in rural Uganda since 2006. However, most rural Ugandan women are not vaccinated due to poor vaccination delivery, negative attitudes towards vaccination, and other social cultural factors. The existing sexual education system run by the Ugandan …

Donation Pick-Up And Tracking App For Columbian Food Bank, Alex Fang, Arren Leung, Adrian Ramirez Lopez, Rodrigo Mejia Jun 2022

Donation Pick-Up And Tracking App For Columbian Food Bank, Alex Fang, Arren Leung, Adrian Ramirez Lopez, Rodrigo Mejia

Computer Science and Engineering Senior Theses

Banco de Alimentos Cali is responsible for picking up food donations from local businesses, organizing by perishable dates, and distributing them to the communities in need. When donations are picked up from the donor, the bank is responsible for sending their donors a certificate with the donation's information, including the dollar equivalent of their donation. This certificate is sent out only if the donor requests it for tax deduction purposes. While this plan may seem simple in theory, the food bank often struggles to get the necessary information from their drivers in regards to the donation, which ultimately delays the …

Halide Perovskites Enable Polaritonic Xy Spin Hamiltonian At Room Temperature, Renjie Tao, Kai Peng, Louis Haeberlé, Quanwei Li, Dafei Jin, Graham R. Fleming, Stéphane Kéna-Cohen, Xiang Zhang, Wei Bao Jun 2022

Halide Perovskites Enable Polaritonic Xy Spin Hamiltonian At Room Temperature, Renjie Tao, Kai Peng, Louis Haeberlé, Quanwei Li, Dafei Jin, Graham R. Fleming, Stéphane Kéna-Cohen, Xiang Zhang, Wei Bao

Department of Electrical and Computer Engineering: Faculty Publications

Exciton polaritons, the part-light and part-matter quasiparticles in semiconductor optical cavities, are promising for exploring Bose–Einstein condensation, non-equilibrium many-body physics and analogue simulation at elevated temperatures. However, a room-temperature polaritonic platform on par with the GaAs quantum wells grown by molecular beam epitaxy at low temperatures remains elusive. The operation of such a platform calls for long-lifetime, strongly interacting excitons in a stringent material system with large yet nanoscale-thin geometry and homogeneous properties. Here, we address this challenge by adopting a method based on the solution synthesis of excitonic halide perovskites grown under nanoconfinement. Such nanoconfinement growth facilitates the synthesis …

Controlled Pre-Wetting Of Spread Powder And Its Effects On Part Formation And Printing Parameters In Binder Jetting Additive Manufacturing, Colton G. Inkley Jun 2022

Controlled Pre-Wetting Of Spread Powder And Its Effects On Part Formation And Printing Parameters In Binder Jetting Additive Manufacturing, Colton G. Inkley

Theses and Dissertations

Binder jetting is an additive manufacturing process that layer by layer builds a 3D model by selectively binding regions of powder using binder deposited though an inkjet printhead. The process offers several advantages over other additive manufacturing processes including fast build rates, vast material selection, decreased cost, and part resolution. The main disadvantage of binder jetting is poor mechanical properties, stemming from a poor understanding of the process physics. Porosity in final parts is not uncommon, but there is little understanding of where the porosity originates. The purpose of this thesis is to report the investigation of increased powder bed …

Augmented Formic Acid Electro-Oxidation At A Co-Electrodeposited Pd/Au Nanoparticle Catalyst, Yaser M. Asal, Ahmad M. Mohammad, Sayed S. Abd El Rehim, Islam M. Al-Akraa Jun 2022

Augmented Formic Acid Electro-Oxidation At A Co-Electrodeposited Pd/Au Nanoparticle Catalyst, Yaser M. Asal, Ahmad M. Mohammad, Sayed S. Abd El Rehim, Islam M. Al-Akraa

Chemical Engineering

In this study, the formic acid electro-oxidation reaction (FAEOR) was catalyzed on a Pd-Au co-electrodeposited binary catalyst. The kinetics of FAEOR were intensively impacted by changing the Pd2+:Au3+ molar ratio in the deposition medium. The Pd1-Au1 catalyst (for which the Pd2+:Au3+ molar ratio was 1:1) acquired the highest activity with a peak current density for the direct FAEOR (Ip) of 4.14 mA cm−2 (ca. 13- times higher than that (ca. 0.33 mA cm−2) of the pristine Pd1-Au0 catalyst). It also retained the highest stability that was denoted in fulfilling ca. 0.292 mA cm−2 (ca. 19-times higher than 0.015 …

Assessing The Impact Of Three Intersection Treatments In A Bicycling Simulator, Logan Scott-Deeter, David Hurwitz, Brendan Russo, Edward Smaglik, Sirisha Kothuri

Civil and Environmental Engineering Faculty Publications and Presentations

Bicyclist safety at urban intersections is a critical element for encouraging an increase in bicycle commuting. With cyclist injury and fatality rates rising due to collisions with vehicles at signalized intersections, increasing the safety of riders continues to be an important consideration when promoting this mode of transportation. Previous research has addressed crash causality and helped to develop several roadway treatments to improve bicyclist safety, but little has been done to compare and contrast the benefits of the various treatment types. This bicycling simulator study examined the impacts of three different intersection treatments (i.e., bike box, mixing zone, and bicycle …

Generating Reality-Analogous Datasets For Autonomous Uav Navigation Using Digital Twin Areas, Thomas Lee, Susan Mckeever, Jane Courtney Jun 2022

Generating Reality-Analogous Datasets For Autonomous Uav Navigation Using Digital Twin Areas, Thomas Lee, Susan Mckeever, Jane Courtney

Conference papers

In order for autonomously navigating Unmanned Air Vehicles(UAVs) to be implemented in day-to-day life, proof of safe operation will be necessary for all realistic navigation scenarios. For Deep Learning powered navigation protocols, this requirement is challenging to fulfil as the performance of a network is impacted by how much the test case deviates from data that the network was trained on. Though networks can generalise to manage multiple scenarios in the same task, they require additional data representing those cases which can be costly to gather. In this work, a solution to this data acquisition problem is suggested by way …

A Qualitative Study Of Emotions Experienced By First-Year Engineering Students During Programming Tasks, Zahra Atiq, Michael C. Loui Jun 2022

A Qualitative Study Of Emotions Experienced By First-Year Engineering Students During Programming Tasks, Zahra Atiq, Michael C. Loui

School of Engineering Education Faculty Publications

In introductory computer programming courses, students experience a range of emotions. Students often experience anxiety and frustration when they encounter difficulties in writing programs. Continued frustration can discourage students from pursuing engineering and computing careers. Although prior research has shown how emotions affect students’ motivation and learning, little is known about students’ emotions in programming courses. In this qualitative study of first-year engineering students taking an introductory programming course, we examined the emotions that these students experienced during programming tasks and the reasons for experiencing those emotions. Our study was grounded in the control-value theory of achievement emotions. Each research …

Climate Projections Over The Great Lakes Region: Using Two-Way Coupling Of A Regional Climate Model With A 3-D Lake Model, Pengfei Xue, Xinyu Ye, Jeremy S. Pal, Philip Y. Chu, Miraj Kayastha, Chenfu Huang

Michigan Tech Publications, Part 1

Warming trends in the Laurentian Great Lakes and surrounding areas have been observed in recent decades, and concerns continue to rise about the pace and pattern of future climate change over the world's largest freshwater system. To date, most regional climate models used for Great Lakes projections either neglected the lake-atmosphere interactions or are only coupled with a 1-D column lake model to represent the lake hydrodynamics. This study presents a Great Lakes climate change projection that has employed the two-way coupling of a regional climate model with a 3-D lake model (GLARM) to resolve 3-D hydrodynamics essential for large …

B2b2: Lidar 2d Mapping Rover, Laurence Kim, Isaiah Youngblood, Quintion Turner Jun 2022

B2b2: Lidar 2d Mapping Rover, Laurence Kim, Isaiah Youngblood, Quintion Turner

Electrical and Computer Engineering Senior Theses

Autonomous machines are becoming more popular and useful with even self-driving cars being a thing of the present. Most of these machines navigate using cameras and LiDAR which does not detect glass, therefore the machines give misleading results when objects and obstacles are transparent to the wavelengths of the light used. This is problematic in modern building floor plans with glass walls. A solution is to build a ROS system that fuses ultrasonic sensors with LiDAR sensors in order for a robot to navigate in a building that has glass walls. Using both sensors, the final product is a robot …
