Investigation On The Influence Of Augmented Reality Adoption And Cybersecurity In The Architecture, Engineering And Construction Industry, Kavyaa Boopathy Jan 2023

Investigation On The Influence Of Augmented Reality Adoption And Cybersecurity In The Architecture, Engineering And Construction Industry, Kavyaa Boopathy

UNF Graduate Theses and Dissertations

Augmented Reality (AR) applications and the digitization of Architecture, Engineering, and Construction (AEC) industry processes, such as the online building permit process (BPP), have introduced new developments that simplifies tasks, and enhanced data accessibility for stakeholders. This created a digital landscape where sensitive information and critical processes are intertwined, making them vulnerable to cyber-attacks. Existing studies and frameworks on a) AR adoption doesn’t provide essential information (e.g., material availability and costs from different suppliers) and AR features to cater to the diverse needs of different stakeholders. b) threat modeling requires a domain and context specific need investigation, process exploration, critical …


Bayesian Approach On Quantifying The Safety Effects Of Pedestrian Countdown Signals To Drivers, Angela E. Kitali Jan 2017

Bayesian Approach On Quantifying The Safety Effects Of Pedestrian Countdown Signals To Drivers, Angela E. Kitali

UNF Graduate Theses and Dissertations

Pedestrian countdown signals (PCSs) are viable traffic control devices that assist pedestrians in crossing intersections safely. Despite the fact that PCSs are meant for pedestrians, they also have an impact on drivers’ behavior at intersections. This study focuses on the evaluation of the safety effectiveness of PCSs to drivers in the cities of Jacksonville and Gainesville, Florida. The study employs two Bayesian approaches, before-and-after empirical Bayes (EB) and full Bayes (FB) with a comparison group, to quantify the safety impacts of PCSs to drivers. Specifically, crash modification factors (CMFs), which are estimated using the aforementioned two methods, were used to …


The Impact Of Various Steel Stud Wall Frame Components On Energy Efficiency Analysis – Case Study, Aiyin Jiang Apr 2013

The Impact Of Various Steel Stud Wall Frame Components On Energy Efficiency Analysis – Case Study, Aiyin Jiang

Construction Management Faculty Research and Scholarship

Steel stud framing is an excellent alternative to wood stud framing in residential construction. Steel framing is structurally sound, sustainable, and resistant to mold and insect infestation. However, the use of steel framing in the residential market remains low, due in large part to concerns on the thermal performance of steel. Over the past several years, engineers and constructors have increased the thermal resistance of steel stud walls through various wall assembly improvements, the impact of these components on energy efficiency is unclear. This study applies computer software to simulate the performance of various steel stud wall system assemblies. This …


Bridge Deck Cracking Investigation And Repair, Vidal Velez Vargas Jan 2012

Bridge Deck Cracking Investigation And Repair, Vidal Velez Vargas

UNF Graduate Theses and Dissertations

The focus of this study is to investigate the cracking of concrete bridge decks and the sealants used in repairing transverse cracks. Cracking could occur in both hardened mature concrete and early age concrete. Several factors affect concrete cracking, such as age-dependent material properties, thermal- and moisture-related stresses and strains, material viscoelastic behavior, restraints, concrete expansion and contraction, casting sequence, formwork, material characteristics, and environmental exposure. The causes of early age cracking are primarily attributed to effects such as plastic shrinkage, temperature effects, autogenous shrinkage, and drying shrinkage. This deck cracking could greatly reduce durability, lead to a loss of …


The Repair Of Laterally Damaged Concrete Bridge Girders Using Carbon Fiber Reinforcing Polymers (Cfrp), Matthew Kent Graeff Jan 2012

The Repair Of Laterally Damaged Concrete Bridge Girders Using Carbon Fiber Reinforcing Polymers (Cfrp), Matthew Kent Graeff

UNF Graduate Theses and Dissertations

In recent years the use of carbon fiber reinforcing polymers (CFRP) to repair damaged structural components has become more accepted and practiced. However, the current reference for designing FRP systems to repair and strengthen reinforced concrete (RC) and prestressed concrete (PSC) girders has limitations. Similarly, very few resources address solutions for the debonding problem associated with CFRP laminates or the use of CFRP laminates to repair structural members with pre-existing damage. The included experimental program consists of testing both RC and PSC girders with simulated lateral damage and CFRP repairs. A total of 34 RC beams were statically tested under …

Location And Economic Study For Interstate Route Tallahassee, Wilbur Smith And Associates Nov 1957

Location And Economic Study For Interstate Route Tallahassee, Wilbur Smith And Associates

City and Regional Planning -- Florida

The basic purpose of the study was to determine the best location for the construction of an East-West section of the interstate highway. It was prescribed that the work would consist of two basic parts. One had to do with the analysis of travel data, both present and projected, in the determination of the most feasible location of a route based on conventional traffic and highway development factors. The other phase of the work was to deal with economic considerations, especially the economic impact of the proposed routes on businesses located on existing roads and on the central business district …
