Venezuela Public Health Issue, Luke Vargas

Global Public Health

While every country around the world faces a form of public health issues, the issues that the country of Venezuela faces are different. Their public health problem is not a disease that can be solved by science, or a cure. It’s a problem that can only be solved by the people within the county itself. The country of Venezuela now lacks the proper medical supplies needed to help cure diseases and normal vaccinations, and the only ones to blame is their government. Because their government has now refused to pay their debts to the surrounding countries they have now lost …

The Democratic Architecture Of George W. Maher: A Preservation Perspective, Cody Chase

Historic Preservation Theses

As a branch of the international Arts and Crafts Movement, American Prairie Style architecture was a nostalgic ode to the horizontality and natural landscape of the Midwestern prairie and a departure from European design. Today, the work of Frank Lloyd Wright and Louis Sullivan comprise the most memorable examples of the era, leaving a considerable number of architects largely understudied. One of these architects was the prolific theoretician and designer George W. Maher.

Ambitious from a young age, Maher had his own firm by his mid-twenties and produced over 160 structures in his thirty-eight-year career. During that time he was …

Mapping Quality Of Life In Nebraska: Migration Rates, Aileen S. Garcia, Rodrigo Cantarero, Grant Daily, Maria Rosario T. De Guzman, Jeong-Kyun Choi, Soo-Young Hong, Sarah Taylor

Mapping Quality of Life in Nebraska

KEY POINTS AND IMPLICATIONS

Nebraska is a state that is not often viewed as affected significantly by mobility and migration. As a state, the net migration rate of 1.1 from 2015 to 2016 is fairly low compared to others like Florida (16.0) or Nevada (14.4). However, data from this report suggests that there is, in fact, substantial movement of people moving in and moving out; as well as pockets within the state where there is higher than average influx of both domestic and international migrants.

In general, migration trends in the state mirror national trends of “rural flight” where people …

Simultaneous Electrical And Mechanical Resonance Drive For Large Signal Amplification Of Micro Resonators, M. H. Hasan, Fadi M. Alsaleem, N. Jaber, M. A. A. Hafiz, M. I. Younis

Durham School of Architectural Engineering and Construction: Faculty Publications

Achieving large signal-noise ratio using low levels of excitation signal is key requirement for practical applications of micro and nano electromechanical resonators. In this work, we introduce the double electromechanical resonance drive concept to achieve an order-of-magnitude dynamic signal amplification in micro resonators. The concept relies on simultaneously activating the micro-resonator mechanical and electrical resonance frequencies. We report an input voltage amplification up to 15 times for a micro-resonator when its electrical resonance is tuned to match the mechanical resonance that leads to dynamic signal amplification in air (Quality factor enhancement). Furthermore, using a multi-frequency excitation technique, input voltage and …

Impact Of Owners’ Early Decisions On Project Performance And Dispute Occurrence In Public Highway Projects, Sogand Hasanzadeh, Behzad Esmaeili, Ghada M. Gad, Douglas D. Gransberg

Durham School of Architectural Engineering and Construction: Faculty Publications

Disputes are common in the construction industry and lead to unnecessary cost and schedule overruns in projects. It is commonly believed that owners’ early decisions regarding the selection of delivery methods, procurement methods, and contract types impact the frequency and severity of project disputes; however, no previous study has empirically tested this hypothesis, particularly in highway public projects. Therefore, this study empirically investigated the impact of owners’ early decisions regarding project organization (i.e., delivery methods, procurement, and contract types) on performance measures (e.g., cost and schedule growth), specifically dispute performance metrics (e.g., frequency and severity of disputes), in public highway …

Numerical Simulation Of Fault Impacts For Commercial Walk-In Freezers, Alireza Behfar, David P. Yuill

Durham School of Architectural Engineering and Construction: Faculty Publications

Refrigeration systems can undergo many faults that could negatively affect their operation and performance. This paper describes a modeling process to simulate the fault impacts on the operation of a commercial walk-in freezer using semi-empirical models. These models often require less modeling effort than full forward models and could be used in scenarios where detailed information is missing, such as in field-measured systems. An important characteristic of a typical walk-in refrigeration system is the existence of a liquid-line receiver after the condenser, which significantly changes the behavior of the cycle, in comparison to a receiver-less system. Component models described in …

Method For Radon Measurement In Residential Sewer Connections, David Yuill

Durham School of Architectural Engineering and Construction: Faculty Publications

Radon gas is the most deadly indoor air pollutant. In the US, it is responsible for over 20,000 deaths per year. Residential exposure is typically the largest portion of a person’s annual exposure, so a great deal of research has been done to understand the pathways that radon can follow to enter a house. Since radon emanates from the ground, it is present in high concentration in soil gas. Recent research on the vapor intrusion of volatile organic compounds from subsurface sources into a test house concluded that the sewer line is an important preferential pathway. Despite the potential for …

Comfort-Based Optimal Temperature Setpoint Calculation, Andrew Holthaus, Mostafa Rafaie, Fadi Alsaleem

Durham School of Architectural Engineering and Construction: Faculty Publications

General practice in current building HVAC control is to select building temperature setpoints that comply with ASHRAE Standard 55. By meeting this standard, based on the PMV comfort model, 80% of building occupants should be satisfied with their thermal environment. However, unfortunately, this is rarely the case. One possible reason for this is the variation in occupant activity and clothing that are usually assumed default values using this standard. In this work, we present an iterative-based algorithm to solve this problem. The algorithm solves the PMV inverse model equation to determine the optimal temperature setpoint while inferring human activity level …

Infrared Thermography For Weld Inspection: Feasibility And Application, Sattar Dorafshan, Marc Maguire, William Collins

Durham School of Architectural Engineering and Construction: Faculty Publications

Traditional ultrasonic testing (UT) techniques have been widely used to detect surface and sub-surface defects of welds. UT inspection is a contact method which burdens the manufacturer by storing hot specimens for inspection when the material is cool. Additionally, UT is only valid for 5 mm specimens or thicker and requires a highly skilled operator to perform the inspections and interpret the signals. Infrared thermography (IRT) has the potential to be implemented for weld inspections due to its non-contact nature. In this study, the feasibility of using IRT to overcome the limitations of UT inspection is investigated to detect inclusion, …
