Effectiveness Of Building Systems Strategies For Mitigation Of Airborne Transmission Of Sars-Cov-2, Meng Kong, Jialei Shen, Bing Dong, Jianshun Jensen Zhang
Mechanical and Aerospace Engineering - All Scholarship
Airborne transmission has been recognized as a major transmission pathway for the infectious disease COVID-19. This study investigated the effectiveness of several indoor air quality (IAQ) control strategies on the mitigation of airborne transmission of SARS-CoV-2, the virus that causes COVID-19. The well-known airborne disease infection risk model (Wells-Riley equation) was used to estimate the infection risk of the SARS-CoV-2 in seven (7) different types of spaces including conference center/ballrooms, hotel bistro//cafeteria, hotel lobby, classrooms (lecture), conference room/small classroom, hotel or cruise ship guest rooms and open plan offices. The IAQ control strategies included increased ventilation rate, improved air distribution …

Recycling Cigarettes Into Concrete, Jonathan R. Rosete
Construction Management
The objective of my senior project is to find a solution for the growing amount of improperly disposed cigarette butts on our planet. To accomplish this, I created and tested concrete cylinders mixed with different amounts of used cigarettes. It is my goal that we will be able to recycle cigarette butts and incorporate them into our everyday concrete use. By adding cigarettes to our mixes, I also understand their will be concerns with its potential strength. However with this in mind, it is my intention that these current mixes will only be used for non-structural concrete. In the following, …
The Use Of Green Pond Conglomerate As Building Stone In Morris County, New Jersey, Gregory A. Pope
The Use Of Green Pond Conglomerate As Building Stone In Morris County, New Jersey, Gregory A. Pope
Department of Earth and Environmental Studies Faculty Scholarship and Creative Works
Green Pond Conglomerate (GPC) is a maroon colored quartzite with white quartz pebbles, a classic “puddingstone”. GPC derives from a NW-SW-trending sliver of Paleozoic sediments, the “Green Pond Outlier”, surrounded by older metamorphic and igneous rocks of Morris and Passaic Counties. Buildings, retaining walls, field fences, and monuments incorporate the durable and attractive stone, in a distinct geographic area of Morris County. Several instances of structures completely constructed or faced with GPC occur in and around Morristown, limited to affluent houses and one prominent church. In these cases, GPC stones were dressed and faced, a labor-intensive effort. Elsewhere in the …

Online Implementation Of Structural Analysis Tool For Remote Learning, Ghada El-Mahdy, Amany Micheal
Civil Engineering
The delivery of a structural analysis module to architectural or civil engineering students needs the visualization of certain diagrams, such as the internal force diagrams and the elastic line. These diagrams are difficult to grasp for students new to structural analysis and need a lot of practice to become proficient in drawing them. Current structural analysis textbooks with electronic platforms do not include tools to draw the internal force diagrams or deflection. This has led to the initiative of creating an online structural analysis tool to enable the student to easily apply different loadings on different statical systems to draw …
Resilience Of School Systems Following Severe Earthquakes, Emad M. Hassan, Hussam N. Mahmoud, Bruce R. Ellingwood
Resilience Of School Systems Following Severe Earthquakes, Emad M. Hassan, Hussam N. Mahmoud, Bruce R. Ellingwood
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Natural disasters may have catastrophic and long-lasting impacts on communities' physical, economic, and social infrastructure. Slow recovery of educational services following such events is likely to cause traumatic stress in children, lead families to out-migrate, and affect the community's overall social stability. Methods for quantifying and assessing the restoration process of educational systems and their dependencies on other supporting infrastructure have not received adequate attention. This study introduces, for the first time, a new framework to evaluate the functionality, recovery, and resilience of a school system following severe earthquake events. The framework considers both the quantity and quality of education …

How Does Three-Dimensional Canopy Geometry Affect The Front Propagation Of A Gravity Current?, Jian Zhou, Subhas K. Venayagamoorthy
How Does Three-Dimensional Canopy Geometry Affect The Front Propagation Of A Gravity Current?, Jian Zhou, Subhas K. Venayagamoorthy
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Large-eddy simulations are performed to investigate how three-dimensional canopy geometry affects the front propagation of an incoming gravity current under a given initial forcing. A regular array of rigid square cylinders are used to represent the distributed canopy elements. It is shown that the conventional geometrical parameter of submerged canopies in constant-density flows (ah, where a is the frontal area per canopy volume and h is the canopy height) is misleading when applied to buoyancy-driven flows due to the additional complexity arising from the internal density gradients. Instead, the present study suggests a new geometrical framework consisting of a canopy …
Co2 Curing Efficiency For Cement Paste And Mortars Produced By A Low Water-To-Cement Ratio, Seong Ho Han, Yubin Jun, Tae Yong Shin, Jae Hong Kim
Co2 Curing Efficiency For Cement Paste And Mortars Produced By A Low Water-To-Cement Ratio, Seong Ho Han, Yubin Jun, Tae Yong Shin, Jae Hong Kim
Civil, Architectural and Environmental Engineering Faculty Research & Creative Works
Curing by CO2 is a way to utilize CO2 to reduce greenhouse gas emissions. Placing early-age cement paste in a CO2 chamber or pressure vessel accelerates its strength development. Cement carbonation is attributed to the quickened strength development, and CO2 uptake can be quantitatively evaluated by measuring CO2 gas pressure loss in the pressure vessel. A decrease in CO2 gas pressure is observed with all cement pastes and mortar samples regardless of the mix proportion and the casting method; one method involves compacting a low water-to-cement ratio mix, and the other method comprises a …
Identifying Challenges To Project Outcomes From A Transportation Project Owner Perspective, Evan D. Bingham, Clifton B. Farnsworth, Rebecca O. Warr, James P. Smith
Identifying Challenges To Project Outcomes From A Transportation Project Owner Perspective, Evan D. Bingham, Clifton B. Farnsworth, Rebecca O. Warr, James P. Smith
The Professional Constructor
Transportation project owners are often concerned with the risks associated with construction, because these challenges can directly affect project outcomes and often lead to increased time and cost for projects. It is, therefore, vital to identify challenges early within the project life cycle. Transportation project delivery has evolved to strengthen the influence that the owner has upon the project, transitioning away from the exclusive use of traditional Design-Bid-Build to the more innovative and involved approaches of Design-Build and Construction Manager / General Contractor. Unfortunately, this has resulted in increased owner risk. In this research, transportation project owners were asked to …
A Culture-Based Analysis Of Construction Management Students’ Conflict Management Styles, David W. Martin
A Culture-Based Analysis Of Construction Management Students’ Conflict Management Styles, David W. Martin
The Professional Constructor
The use of collaborative project delivery systems in the construction industry requires cooperation and shared management of the construction process to achieve success. This growth in collaborative systems requires project representatives to effectively manage conflict. Project failures utilizing collaborative methods are frequently attributed to an inability of project representatives to collaboratively resolve conflict. Research suggests that minorities are prone to use a collaborative conflict management style and the inclusion of minorities in construction management (CM) roles can reduce negative conflict. The growing evidence that increasing workforce diversity in CM is beneficial to the industry indicates that there is value in …

Role Of Infrastructure In The Success Of Residential Developments In Michigan, Aditi Hardekar, M.G. Matt Syal
The Professional Constructor
Infrastructure systems are critical for the success of a residential development. These systems include the infrastructure within and around the development as well as facilities and amenities in the surrounding area. Most of the residential development literature tend to focus on the planning, layout, social aspects, and the residential units itself, but lack emphasis on the infrastructure systems. This paper identified supporting infrastructure for residential developments based on the review of research and industry literature, and several case studies nationwide. The availability and absence of infrastructure systems were investigated in each case study. The review led to the identification of …
Analyzing The Safety Effects Of Edge Lane Roads For All Road Users, Marcial F. Lamera
Analyzing The Safety Effects Of Edge Lane Roads For All Road Users, Marcial F. Lamera
Master's Theses
This thesis acts as one of the first studies that analyzes the safety effects of Edge Lane Roads (ELR) for all road users. This is important since ELRs can be a solution to many issues, such as alleviating congestion, increasing multimodality along roadways, and reducing maintenance costs. ELRs in both North America and Australia were observed. Starting with the North American ELRs, the following study designs were employed to estimate the safety of ELRs: (a) yoked comparison where each ELR installation was matched with at least two comparable 2-lane roads to serve as comparison sites and (b) an Empirical Bayes …

Change Management In Construction: Necessity, Obstacles,And Suggested Solutions, Ihab M. H. Saad
The Professional Constructor
The construction industry is one of the major harbingers of the economy of any industrialized nation. Its contribution to the Gross Domestic Product is undeniable. The major economic downturn that lasted from 2008 to 2011 resulted in a lot of change in the industry personnel at both the administration and labor force levels. This resulted in expediting the retirement of a generation of seasoned professionals, and creating a gap in the ranks of construction firms that is still to be completely filled. Similar impacts followed the uncertainty resulting recently from Covid-19 and the economic instability and uncertainty it caused. One …

Pert, Cpm And The Tangled History Of Network Scheduling, Charles Christopher Smith, Vivek Sharma, Gregory B. Baecher
The Professional Constructor
The origins of two network scheduling techniques: The Program Evaluation Review Technique (PERT); and the Critical Path Method (CPM) are examined. Prior accounts hold that each are different and were created separately. PERT, developed within the U. S. Navy’s highly classified POLARIS nuclear missile program which began in 1955. CPM, the creation of American industrial concerns E. I. du Pont de Nemours (du Pont) and Remington Rand UNIVAC. With the objective of settling “an acrimonious dispute over parentage,” this research examines the literature and the original forms of PERT and CPM noting their ‘dead ring’ resemblances, synchronous development timelines, while …
