Math Anxiety In Female And Underrepresented Minority Students A Literature Review, Anne M. Lucietto, Meher Rusi Taleyarkhan, Therese M. Azevedo, Natalie Hobson Jun 2020

Math Anxiety In Female And Underrepresented Minority Students A Literature Review, Anne M. Lucietto, Meher Rusi Taleyarkhan, Therese M. Azevedo, Natalie Hobson

School of Engineering Technology Faculty Publications

Educators have noticed that some students respond to exercises requiring mathematical calculations with numerical answers that are not correct and far from realistic. These student solutions are often given without further comment or calculation by the students and seem to such avoidance by the students to engage with the numerical calculations. Anecdotal evidence, by these educators, suggest that such responses are more prevalent from female and underrepresented minority groups — raising the question of whether demographics play a role in a students’ approach to numerical problems. Researchers have searched for existing work in this area and find that there are …

Public Perception Of Engineering Technology: A Literature Review, Anne M. Lucietto, Shelly Tan, Liza Ann Russell, Mary E. Johnson Jun 2020

Public Perception Of Engineering Technology: A Literature Review, Anne M. Lucietto, Shelly Tan, Liza Ann Russell, Mary E. Johnson

School of Engineering Technology Faculty Publications

Engineering technology describes a field closely related to engineering in which practical application of learned concepts is emphasized over theoretical knowledge. Although an increasing amount of emphasis is being placed on the importance of this experiential learning in all engineering curricula, and the specifics of engineering technology’s place among engineering and technical fields is becoming clearer, there are still significant gaps in our understanding of several key aspects of this field. One of these aspects is its perception by the general public, which is important in, among other things, determining the employability of engineering technology program graduates and encouraging the …

Introducing Sequencing Within The Advanced Scheduling Curriculum, Adam Cole Alvarez Jun 2020

Introducing Sequencing Within The Advanced Scheduling Curriculum, Adam Cole Alvarez

Construction Management

Scheduling is one of the most important factors within the construction industry. The current Advanced Scheduling curriculum addresses how to use the program P6, but not the understanding of how to sequence. This project introduced two new lab activities that focus on the understanding of sequencing while using P6. I chose this project because I have always had an interest in scheduling as it is one of the most important driving factors in construction and after taking Advanced Scheduling in my Junior year I noticed there is a need for understanding sequencing. I wanted to introduce a new curriculum because …

Synthesis And Characterization Of Porous Carbon Composite Derived From Biomass Waste For Supercapacitor Application, Cheng Kim Sim

Student Works (2020-2029)

Energy storage devices have gradually dominated human daily activities and indispensable to economy development such as supercapacitor and battery. There are few factors determining the performance of supercapacitor and active material is one of the crucial. Therefore, biomass such as pineapple peel (PP) and green waste (GW) were preferred and prior mixed with manganese and tin carbonate to synthesize carbon composite (PP/GW-ZMO and PP/GW-ZTO) via combustion. Brunauer–Emmett–Teller (BET) was employed to study the textural properties with the highest specific surface area obtained in PP-C (1765.92 m2g-1) and GW-C (1613.92 m2g-1).

The Relationship Between Mental Workload And Driving Performance Of Ageing Drivers, Abd Rahman Nurul Izzah Jun 2020

The Relationship Between Mental Workload And Driving Performance Of Ageing Drivers, Abd Rahman Nurul Izzah

Student Works (2020-2029)

The population of ageing drivers is increasing rapidly. As ageing happened, they are exposed to disabilities due to degenerative processes, thus affecting their driving performance. For changes in driving method or design to occur, ageing drivers’ driving tasks need to be monitored, designed and tested. Comprehensive research needs to be conducted to investigate how to integrate mental workload with driving performance of ageing people. Moreover, there has been no study yet that develop a model to predict overall driving performance in Malaysia. Hence, the main objective of this study is to develop and validate a model which quantifies the mental …

Optimized System For On-Route Charging Of Battery Electric Buses And High-Fidelity Modelling And Simulation Of In-Motion Wireless Power Transfer, Yogesh Bappasaheb Jagdale Jun 2020

Optimized System For On-Route Charging Of Battery Electric Buses And High-Fidelity Modelling And Simulation Of In-Motion Wireless Power Transfer, Yogesh Bappasaheb Jagdale

Masters Theses

Electrifying cars, buses and trucks is an attractive means to reduce energy use and emissions, because it involves minimal restructuring of the transportation network. Transit buses drive fixed routes, minimizing driver range anxiety by properly sizing energy storage system but the major challenge to fully electrifying transit buses, is the amount of energy they consume in a day of driving. To enable a full day of operation, batteries need to be large, which is expensive and heavy. This work utilizes real-world transit bus data fed to a battery electric drive-train model to co-optimize charger locations, charger power levels, and vehicle …

Effectiveness Of Building Information Modeling In Existing Structure Construction Compared To New Structure Construction, Anthony Aaron Bellanti Jun 2020

Effectiveness Of Building Information Modeling In Existing Structure Construction Compared To New Structure Construction, Anthony Aaron Bellanti

Construction Management

Over the last decade Building Information Modeling has become a crucial aspect of the construction project for larger construction firms in the United States. BIM has many different facets and can be used to effectively manage construction projects in various ways. Modeling a structure in a virtual setting in preconstruction allows for adequate preparedness for the construction process and has been shown to be effective, on a broad scale, to reduce cost, compress schedules, and allow for a more fluid construction process overall. The goal of this paper is to look more closely at BIM and its effectiveness on existing …

Fitting In: Analyzing The Fit Of Safety Vests In The Construction Industry, Lizette Galvez Puentes

Construction Management

The construction industry continues to be a male-dominated industry; however, recent decades have seen a change of demographic, including an increase of women leadership. With the changing demographics, there is a lack of awareness and proactive integration of properly fitting safety vests to accommodate different body types. A properly fitting safety vest is crucial in upholding the safety of individuals working on a construction site, where certain genders are more frequently caught on jobsite material. These circumstances hinder the purpose and functionality of the safety vest’s primary functions, which, for the wearer, is increased visibility and the comfort to carry …
