Engineering and Applied Science Education Faculty Publications

In this paper, we describe an innovative curricular model employed at the University of New Haven to develop an entrepreneurial mindset in engineering students. The entrepreneurial mindset in this model is characterized by the Kern Entrepreneurial Engineering Network (KEEN)’s 3C’s, which are curiosity, connections and creating value. The core of the model is the integration of short, self-paced, e-learning modules into courses spanning all four years of all engineering and computer science programs. A flipped classroom instructional model is used to integrate the modules into courses. We are in the third year of implementation on campus, and following a pilot …

Influencing Student Motivation Through Scaffolded Assignments In A Quality Analysis Course And Its Impact On Learning, Nadiye O. Erdil

Engineering and Applied Science Education Faculty Publications

This paper discusses the impact of various class assignments and activities that build upon each other with the aim of increasing student motivation and student learning in a Quality Analysis course. Scaffolding is an instructional strategy that aims to reduce the amount of cognitive effort that students have to make to learn the materials by breaking down the material into more manageable components. In this study, critical thinking scaffolding is applied in the quality analysis course by structuring several elements to lead students to an assignment that is more complex. At the end of the semester, the impact assessment of …

Establishment Of Innovative Shared Departments To Advance Interdisciplinary Education, Ronald S. Harichandran, Brian Kench, Summer Mcgee, Michael A. Collura, Jean Nocito-Gobel, Charles David Skipton

Engineering and Applied Science Education Faculty Publications

More and more universities are pursuing interdisciplinary academic activities that span across department and college boundaries. Administrative structures to facilitate such programs are difficult to establish within traditional university frameworks consisting of disciplinary departments and colleges. Often interdisciplinary programs are housed in a traditional disciplinary department or college, or in a standalone center reporting to a college dean or the provost. The difficulty of these structures is obtaining broad buy-in from faculty across departments and having disciplinary degree programs include interdisciplinary coursework.

To overcome the difficulties described above, an innovative shared department structure that fosters collaborations to advance interdisciplinary education …

Strategic Level Proton Therapy Patient Admission Planning: A Markov Decision Process Modeling Approach, Shengfan Zhang, Ridvan Gedik, Chase Rainwater

Mechanical and Industrial Engineering Faculty Publications

A relatively new consideration in proton therapy planning is the requirement that the mix of patients treated from different categories satisfy desired mix percentages. Deviations from these percentages and their impacts on operational capabilities are of particular interest to healthcare planners. In this study, we investigate intelligent ways of admitting patients to a proton therapy facility that maximize the total expected number of treatment sessions (fractions) delivered to patients in a planning period with stochastic patient arrivals and penalize the deviation from the patient mix restrictions. We propose a Markov Decision Process (MDP) model that provides very useful insights in …

A Three-Year Study Of Adult Undergraduate Engineering Students, Maria-Isabel Carnasciali, Shannon Ciston, Tressa Kay Mikel, Aida Marie Morales, Sanya Sehgal, Melissa L. Whitson

Engineering and Applied Science Education Faculty Publications

Adult learners belong to a large group of individuals for whom lifelong learning is both a desire and a necessity and for whom career changes are or will be the norm. This topic is not exclusive to engineering, but impacts many STEM professionals. Adult learners also include those who may have significant family responsibilities, medical issues, work obligations, returning veterans/active service military people, or those who lack financial resources to commit to fulltime studies. While online education opportunities may fill some of the gaps, acquiring an identity as a professional in a field or discipline grows with personal connections. The …

A Constraint Programming Approach For The Team Orienteering Problem With Time Windows, Ridvan Gedik, Emre Kirac, Ashlea Bennet Milburn, Chase Rainwater

Mechanical and Industrial Engineering Faculty Publications

The team orienteering problem with time windows (TOPTW) is a NP-hard combinatorial optimization problem. It has many real-world applications, for example, routing technicians and disaster relief routing. In the TOPTW, a set of locations is given. For each, the profit, service time and time window are known. A fleet of homogenous vehicles are available for visiting locations and collecting their associated profits. Each vehicle is constrained by a maximum tour duration. The problem is to plan a set of vehicle routes that begin and end at a depot, visit each location no more than once by incorporating time window constraints. …
