Along with the limited studies, we propose a survey to quantify and analyse students’ views on automation. The shift in employment rate in various sectors due to automation was found to be a contributing factor for students’ career decisions. Based on our findings, we observed that more students are acknowledging the impact of automation and finding the need for job securities and opportunities by …

Out Of Mind: Undergraduate Predictors Of Generalized Anxiety Disorder Symptoms, Michael S. Lanzaro

Honors Theses

Demographic factors associated with anxiety have been studied extensively and are often characterized by interconnected relationships. These associations between variables provide insight into the predictive ability of anxiety in undergraduate populations. However, few studies if any have investigated the relationships between class level, sex, honors status, and undergraduate specialization as predictors of anxiety among an undergraduate American university sample. The results of this study provide key insight into the psychopathological development of undergraduate students and anxiety levels as it pertains to academic and demographic variables. By using a multiple linear regression analysis, demographic variables of American undergraduate students are compared …

The Quaternion Algebra And Its Connections To Medical Imaging, Eli Q. Brottman

Honors Capstones

Pure mathematics topics have widely been regarded as having few practical applications; however, over time, many applications have arisen. One such application is using the quaternions, an abstract algebraic structure and extension of the complex number system, to enhance image quality. Quaternion numbers take the form z = a + bi + cj + dk, where a, b, c, d are real numbers, and i, j, k are distinct square roots of −1. By having three distinct square roots of −1, rather than just one (as in the standard complex number system), unique mathematical properties and practical uses arise. Quaternions …

Diabetes Education In The Emergency Department: Decreasing Repeat Visits And Admissions, Keith Hatfield

MSN Capstone Projects

Parkland Memorial Hospital (PMH) has many patients with diabetes under its care (Parkland Health & Hospital System, 2019a). Lewis et al. (2015) found that most patients with diabetes seeking care in a large urban ED lacked the basic diabetes survival knowledge needed to stay healthy. Poor diabetes control leads to complications and illness, which leads to repeat ED visits and inpatient admissions. A further literature review supported providing patients with additional diabetes education to reduce admissions.

This project will train the ED Registered Nurses (RN) to provide additional diabetes education at discharge and provide the patient with educational materials to …

The Relationship Between Early Discharge Planning And Length Of Stay, Kandiss Hearn

MSN Capstone Projects

Discharge planning (DCP) and early discharge intervention has proven to have a direct effect on reducing hospital length of stay (LOS), reducing readmissions, reducing patient morbidity, improving patient satisfaction and possibly reducing patient healthcare cost. This proposal specifically addresses hospital length of stay but with research it was found that early DCP also has the potential to improve outcomes in several areas adjacent to both the patient aspect and business aspect of health care. The proposed question is as follows: In adult hospitalized patients (P), how does discharge planning within the first 24 hours of admission (I) compared to late …

Housing Prefabrication And Resource Optimization, Megan Scherpereel

Honors Theses

Enclosure during construction is often time-consuming, expensive, and at the mercy of the weather. By introducing methods for manufacturing prefabricated enclosure components such as wall panels and roof sections, the impact of the three major variables is reduced. Designs for trusses, roof sections, wall sections, and foundations were developed and selected using civil engineering principles; and manufacturing and logistical processes were optimized using engineering and project management skill sets. These multi-disciplinary efforts were combined to create an accessible and versatile set of designs and instructions that can improve the effectiveness of both a skilled and non-skilled volunteer workforce. By creating …

Primal-Dual 2-Approximation Algorithm For The Monotonic Multiple Depot Heterogeneous Traveling Salesman Problem, S. Rathinam, R. Ravi, J. Bae, K. Sundar

Michigan Tech Publications, Part 1

We study a Multiple Depot Heterogeneous Traveling Salesman Problem (MDHTSP) where the cost of the traveling between any two targets depends on the type of the vehicle. The travel costs are assumed to be symmetric, satisfy the triangle inequality, and are monotonic, i.e., the travel costs between any two targets monotonically increases with the index of the vehicles. Exploiting the monotonic structure of the travel costs, we present a 2-approximation algorithm based on the primal-dual method.

Estimation Of Mean Velocity In Mountainous Streams And The Effect Of Slope And Froude Number., M. Attia

Mansoura Engineering Journal

It is necessary to estimate the mean velocity and thus the corresponding discharge in the ungauged mountainous streams, but the flow resistance equations available for this purpose require further testing and development for mountainous streams. Such streams are characterized by coarse bed materials, steep slopes and small water depths. For these conditions, boulders, cobbles and gravels protrude well into or completely through the flow, and the bed roughness is very large. In the present attempt, equations of Darcy - Weisbach friction factor were developed already to address this problem from which the mean velocity can be predicted. Data of different …

Freshly Compressed Fiber Reinforced Concrete., A. Al-Tuhami, M. Seleem

Mansoura Engineering Journal

One of the most famous problems in concrete Technology is reducing the water cement ratio (w/c) to obtain high strength concrete. An innovative method 10 do so is to compress the freshly caste concrete under pressure using special Trains. The method remarkably reduces the water-cement ratio through expelling the excess water from the mix. In addition, compressing the freshly cast concrete resulting in packing the concrete particles together which reduces the voids and increase the interlocking between aggregates. Consequently, the resulting concrete from this process has higher compressive strength, lower water-cement ratio. In addition, the uses of natural fiber add …
