A Novel Spatiotemporal Prediction Method Of Cumulative Covid-19 Cases, Junzhe Cai
A Novel Spatiotemporal Prediction Method Of Cumulative Covid-19 Cases, Junzhe Cai
Department of Computer Science and Engineering: Dissertations, Theses, and Student Research
Prediction methods are important for many applications. In particular, an accurate prediction for the total number of cases for pandemics such as the Covid-19 pandemic could help medical preparedness by providing in time a sufficient supply of testing kits, hospital beds and medical personnel. This thesis experimentally compares the accuracy of ten prediction methods for the cumulative number of Covid-19 pandemic cases. These ten methods include two types of neural networks and extrapolation methods based on best fit linear, best fit quadratic, best fit cubic and Lagrange interpolation, as well as an extrapolation method from Revesz. We also consider the …

Understanding Of Aerosol Transmission Of Covid 19 In Indoor Environments, Adama Barro, Cathal O'Toole, Jacob S. Lopez, Matthew Quinones, Sherene Moore
Publications and Research
Our reason for discussing severe acute respiratory syndrome corona virus 2 (SARS-CoV-2) or 2019 novel corona virus (Covid-19), is to understand its aerosol transmission characteristics in indoor spaces and to mitigate further spread of this disease by designing a new HVAC system. The problem that we are tackling is the spread of covid-19 droplets through aerosol transmission by looking at potential engineering solutions to the existing HVAC systems. The purpose is to eradicate the spread of the COVID-19 by testing indoor spaces in an effort to understand the effectiveness of ventilation controls. We believe that scientists and engineers have not …
An Analysis Of The Cost Impacts Experienced By Drywall Subcontractors During Covid-19, Brenden Schow
An Analysis Of The Cost Impacts Experienced By Drywall Subcontractors During Covid-19, Brenden Schow
Construction Management
Covid-19 has presented issues in many forms for the drywall tenant improvement (TI) industry due to regulations and restrictions instilled in the Bay Area, California. This report details appropriate implementation of force majeure clause in contracts, stay-at-home orders with regard to construction and updated OSHA requirements. It then goes into analysis on cost impacts observed by various drywall companies operating in the Bay Area and how they are created and controlled. This analysis is supported by interviews conducted with representatives from six different drywall subcontractors who are involved in the estimating and bidding process. Interviews consisted of eight open ended …
Case Study: Effects Of Covid-19 On A Mid-Size San Francisco Commercial General Construction Company, Andrew G. Maxwell Jr
Case Study: Effects Of Covid-19 On A Mid-Size San Francisco Commercial General Construction Company, Andrew G. Maxwell Jr
Construction Management
The Covid-19 pandemic has had an adverse effect on the commercial construction industry. New safety procedures and regulations set by local government and health officials have made it difficult for construction to proceed at the efficiency level it had prior to the pandemic. The San Francisco Bay Area was subject to strict protocols starting in March of 2020 that vastly limited the capability of construction companies to perform work. This case study looks into the ways in which a mid sized commercial general construction contractor from the San Francisco Bay Area was impacted by Covid-19 and the methods they used …

An Augmented Reality Multimedia Learning Platform Assisting Online Lecture Delivery Of Engineering Classes: An Hvac Course, Huojan Yang, Jiaming Zhao, Tianyi Liang, Siqing Zheng, Nikolas R. Kukert, Jun Kong
ASEE North Midwest Section Annual Conference 2020 Publications
Background: The ongoing COVID-19 pandemic has recently resulted in an emergent shift of traditional instruction to (presumably temporary) online delivery, and many students were not able to participate in practical activities (e.g., laboratory experiments) due to inaccessible or unavailable “brick and mortar” laboratories. Purpose: This works-in-progress paper developed a multimedia learning platform with virtual laboratory modules through an Augmented Reality (AR) environment, where virtual objects (augmented components) are superimposed onto a real learning setting during online lecture instruction. Specifically, to facilitate students’ gaining practical skills, a library of virtual objects were established for the main physical components or systems related …
