The Impact

In collaboration with a local industry, Rexnord Technologies, mechanical engineering undergraduate students at the Milwaukee School of Engineering have undertaken a series of senior design projects to solve practical problems in thermal engineering. A team of four students are working on Gearbox oil immersion heater control. This team is developing a control scheme to preheat the oil prior to gear movement and that which will ensure that the heater turns off at the correct time so as to maintain the oil temperature in V-series gearboxes. Another team of four students is tackling Gearbox forced convection heat dissipation-modeling and optimization. The beneficial effects of university-industry alliance and the development of well-rounded engineers are discussed along with the solutions for the specific projects. Assessment results highlighting the impact of senior design in the overall undergraduate curriculum are also be presented in this paper. The senior exit surveys also provide the premium value on senior design experience and industry involvement. The goal of this paper is to give the audience a taste of the senior design opportunities undergraduates have at the Milwaukee School of Engineering highlighting the Rexnord Technologies-sponsored projects and the role of industry collaboration.

The Impact

A well formed senior design project is known to have significant benefits in terms of project outcome, student motivation, team cohesiveness, engagement, and student learning. Defining a good problem statement, forming a team of compatible and appropriately skilled students, and selecting an appropriate faculty mentor are critical aspects of project formation. Therefore, students in Mechanical Engineering at Purdue University are encouraged to suggest project ideas, form teams, and have them approved by the course coordinator before the semester starts. While there is significant literature on senior design projects, most of the existing work is focused on activities after the problem is defined and the teams are formed. There is a lack of mechanisms and tools to guide the project formation phase in senior design projects, which makes it challenging for students and faculty to collaboratively develop and refine project ideas and to establish appropriate teams. To address this challenge, we have implemented an online collaboration tool to share, discuss and obtain feedback on project ideas, and to facilitate collaboration among students and faculty prior to the start of the semester. Through an online survey and questionnaire to students, we are exploring the impact of the collaboration tool on the senior design project formation process. In this paper we present the design of the tool and the results from our ongoing study in the senior design class at Purdue Mechanical Engineering.

Abstract The objective of this research is to understand how different representations of requirements influence idea generation in terms of quantity, addressment, sketch detail, novelty, and variety of conceptual sketches. Requirements are statements of need, desires, and wishes of the stakeholders that are used by engineers to frame the problem. Essentially, requirements are the raison d’etre for any engineering project. As the requirements document provides constraints and criteria for a design, it defines and determines the success of a project. While there is research studying the effect of requirements on the conceptual sketch, little study has focused one the impact of different requirement representations on solution development. An experimental study was conducted with 52 fourth year mechanical engineering undergraduate students. Two design problems were formulated with three different representations: a problem statement with embedded requirements, a problem statement and a traditional requirement list, and a problem statement with contextualized scrum stories. Each student was provided each design problems with two different representations of requirements. It was found that the use of contextualized scrum story representations significantly affected the conceptual sketch in the novelty of solution fragments and addressment of requirements, while no significant change in variety, sketch detail, and quantity was seen. Also, the contextualized representation positively affected all metrics but the sketch quantity. Finally, it was found that quantity is not directly related to the number of requirements addressed in the sketches.

Design is seen as the magic word and being a design engineer is considered to be the key to success in the job market by many of the mechanical engineering students. However, it is always assumed that the mechanical systems not the thermal engineers are indeed design engineers by education and practice. This notion probably stems from the fact that most of the thermal fluid courses in mechanical engineering curriculum seem to have been defined and developed to prepare undergraduate students for going to graduate school rather than the job market. The undergraduate courses usually emphasize on the theories with less attention to the design and application aspects. Perhaps, the responsibility of thermal engineering educators is to correct this notion by emphasizing more on the application and design in the existing courses or alternatively to develop and offer new courses on more applied topics. In this paper, we will report an integrated approach in teaching topics in fins and fin assemblies, which includes class lectures, laboratory experiments, ANSYS simulations and design competition. In this manuscript, we will report on the details of this approach including the procedures, methods, our observations, and the students’ feedbacks.

Design And Construction

Teaching senior design courses and labs has not been an easy task for the two authors. It has been rather a daunting working task associated with great learning experiences. It was decided early on from the initiation of the mechanical engineering program at the McCoy School of Engineering at Midwestern State University that the senior design project within the senior design class is a testing and enriching experience for senior mechanical engineering students as well as the teaching faculty. The senior design course and labs are conducted as a research experience for undergraduate students and their assigned faculty. The proposed senior project spans over two semesters, fall and spring, where the students experience a full mechanical engineering related project from the inception phase, through the design and construction phases, and finishing with the testing and analysis phases. The inception phase stands essentially for the brainstorming phase where the students are required to come-up with a set of diverse solutions to their assigned project problem. The design and construction phases stand for choosing an optimal particular solution for their problem according to a set of defined criteria. Then, the students start the preliminary design phase with related cost estimation, and then finalize the design with a set of final drawings. After the design phase, the students start building a machine, an apparatus, a prototype or putting together the elements of a process. In this period they work intensely, with their faculty, the purchasing department, and mostly the department machinist, or the surrounding town machine shops. The testing and analysis phase stands for designing an experimental set-up, writing a testing procedure, and obtaining real time recorded data and proceeding with its analysis. In this technical paper, the authors talk about the requirements for a senior project known as the deliverables, the teaching tools used throughout the class work and labs, the students’ partial and final PowerPoints presentations and weekly and final reports. The authors describe the students overall achievements, and the archiving of the projects. Additionally, the authors talk about the twists and turns encountered during a senior project, with students, other faculty, the machinist, the lab technician, the secretary, and suppliers, and other difficulties experienced in running a full project with real final products. Finally, the authors talk about the aftermath of a senior project, eventual publications related to the project, and what is the view point of the American Board of Engineering and Technology (ABET) on these senior projects.

L2 Pronunciation

Recent research has shown that beat gestures (hand gestures that co-occur with speech in spontaneous discourse) are temporally integrated with prosodic prominence and that they help word memorization and discourse comprehension. However, little is known about the potential beneficial effects of beat gestures in second language (L2) pronunciation learning. This study investigates the impact of beat gesture observation on the acquisition of native-like speech patterns in English by examining the effect of a brief training with or without beat gestures on participants’ ratings of accentedness. In a within-participants, pre-/post-test design, participants (undergraduate students learning English as a foreign language) watched a training video in which an L2 instructor gave spontaneous responses to discourse prompts. The prompts belonged to one of two categories (easy and difficult), and were presented by the instructor either with or without accompanying beat gestures. Participants’ own answers to the prompts were recorded before and after training and evaluated by five native speaker judges. The results of the comparison between the participants’ pre-training and post-training speech samples demonstrated that beat gesture training significantly improved the participants’ accentedness ratings on the set of difficult (more discourse-demanding) items. The results of the study support the role of beat gestures as highlighters of rhythmic information and have implications for pronunciation instruction practices.

Modern internet technologies have revolutionized the traditional education by providing flexible and resourceful e-learning opportunities in all the fields of knowledge. Programming constitutes integral part of undergraduate curriculum in computer sciences, and adequate level of programming expertise is expected from the graduates. In this paper, we explore and examine key factors that contribute to developing programming skills among undergraduate students in e-learning. These factors include teaching practices, intrinsic factors, efficacy problems, and learning intentions. We present a research model by integrating teaching practices, intrinsic factors, and efficacy problems with learning intentions of programming. This study involved responses from 460 undergraduate students. Structural Equation Modelling was applied to develop and evaluate the relationship between factors of the model. Experimental results show that teaching practices and student intrinsic motivations play a pivotal role in promoting learning intentions for programming. Further investigation reveals that learning intentions positively affect the programming expertise while the impact of efficacy problems is negative. The results proclaim that well-organized teaching practices and intrinsic factors develop learning intentions in students which overcome the efficacy problems and lead to better programming expertise. This research provides critical implications for policymakers to effectively implement computer science programs in e-learning paradigm.

Purpose Future speech-language pathologists are often unprepared in their academic training to serve the communicative and cognitive needs of older adults with dementia. While negative attitudes toward older adults are prevalent among undergraduate students, service learning has been shown to positively affect students' attitudes toward older adults. TimeSlips is an evidence-based approach that has been shown to improve health care students' attitudes toward older adults. The purpose of this study is to explore the change in attitudes in speech-language pathology students toward older adults using TimeSlips in service learning. Method Fifty-one students participated in TimeSlips service learning with older adults and completed the Dementia Attitude Scale (DAS) before and after service learning. In addition, students completed a reflection journal. The DAS data were analyzed using nonparametric statistics, and journal entries were analyzed using a qualitative analysis approach. Results The service learners exhibited a significant increase in positive attitude as indexed on the DAS. The reflective journal entries supported the positive change in attitudes. Conclusions A noticeable attitude shift was indexed in reflective journals and on the DAS. TimeSlips is an evidence-based, patient-centered approach well suited to address challenges in the preparation of Communication Sciences and Disorders students to work with the growing population of older adults.

Latent heat storage has shown a great potential in many engineering applications. The utilization of latent heat storage has been extended from small scales to large scales of thermal engineering applications. In food industry, latent heat has been applied in food storage. Another potential application of latent heat storage is to maintain hot beverages at a reasonable drinking temperature for longer periods. In the present work, a numerical calculation was performed to investigate the impact of utilizing encapsulated phase change material PCM on the temperature of hot beverage. The PCM was encapsulated in rings inside the cup. The results showed that the encapsulated PCM reduced the coffee temperature to an acceptable temperature in shorter time. In addition, the PCM maintained the hot beverage temperature at an acceptable drinking temperature for rational time.

The Impact

This study aims to investigate the impact of parental career behaviors on undergraduate student’s career exploration and the mediating role of career self-efficacy. In the literature it is suggested that some social and individual factors facilitate students’ career exploration. Therefore, parental career behaviors and career self-efficacy is considered as predictors of student’s career exploration attitudes within the scope of the study. In this respect, data which are collected from 405 undergraduate students having an education on tourism and hotel management field by the survey method are analyzed by using the structural equation modeling. The results of the study indicate that parental career behaviors which are addressed support; interference and lack of engagement have a significant effect on student’s career exploration behaviors such as intended-systematic exploration, environment exploration and self-exploration. In addition, it has been found that one of the dimensions of parental career behaviors addressed as a lack of engagement has a significant effect on career self-efficacy levels of students. However, research results indicate that student’s career self-efficacy has a significant effect on only the self-exploration dimension. On the other hand, career self-efficacy has a partial mediating role between lack of engagement attitudes of parents and career exploration behaviors of students.

The Impact

Enormous successes have been obtained against the control of major epidemic diseases, such as SARS, MERS, Ebola, Swine Flu in the past. Dynamic interplay of biological, socio-cultural and ecological factors, together with novel aspects of human-animal interphase, pose additional challenges with respect to the emergence of infectious diseases. The important challenges faced in the control and prevention of emerging and re-emerging infectious diseases range from understanding the impact of factors that are necessary for the emergence, to development of strengthened surveillance systems that can mitigate human suffering and death. The aim of the current study is to assess the awareness of symptomatic differences between viral diseases like COVID-19, SARS, Swine flu and common cold among dental students that support the prevention of emergence or re-emergence. Cross-sectional type of study conducted among the undergraduate students comprising 100 Subjects. A questionnaire comprising 15 questions in total were framed, and responses were collected in Google forms in SPSS Software statistical analysis. The study has concluded that dental students have an awareness of the symptomatic differences between infectious viral disease. The study concluded that the awareness of symptomatic differences between viral diseases like COVID-19, SARS, Swine flu, Common cold is good among the dental students who would pave the way for early diagnosis and avoid spreading of such diseases. A further awareness can be created by regular webinars, seminars and brainstorming sessions among these healthcare professionals.
