Embedding Sustainability In Lean Six Sigma Efforts, Nadiye O. Erdil, Can B. Aktas, Omid M. Arani

Mechanical and Industrial Engineering Faculty Publications

The emphasis on the concept of sustainability in businesses and operations is growing either due to increasing public interest, regulatory pressures, or corporate social responsibility. However, where and how to integrate sustainability needs further development for broadening its applications. Using Lean and Six Sigma (LSS) principles in sustainability studies is becoming popular in research and practice. The common approach in these studies is to identify a sustainability project followed by current state sustainability performance assessment, and then work towards improving sustainability performance using LSS tools. The goal of this study was to develop a model framework to fully embed sustainability …

Evaluating The Effect Of Shear Stress On Graft-To Zwitterionic Polycarboxybetaine Coating Stability Using A Flow Cell, Andrew Belanger, Andre Decarmine, Shaoyi Jiang, Keith Cook, Kagya Amoako

Mechanical and Industrial Engineering Faculty Publications

The effect of surface coatings on the performance of antifouling activity under flow can be influenced by the flow/coating interactions. This study evaluates the effect of surface coatings on antifouling activity under different flows for the analyses of coating stability. This was done by exposing DOPA-PCB-300/dopamine coated polydimethylsiloxane (PDMS) to physiological shear stresses using a recirculation system which consisted of dual chamber acrylic flow cells, tygon tubing, flow probe and meter, and perfusion pumps. The effect of shear stress induced by phosphate buffered saline flow on coating stability was characterized with differences in fibrinogen adsorption between control (coated PDMS not …

Quality Function Deployment: More Than A Design Tool, Nadiye O. Erdil, Omid M. Arani

Engineering and Applied Science Education Faculty Publications

Purpose – This study investigates to what extent QFD can be used in quality improvement rather than design activities.

Design/methodology/approach – A framework was developed for implementation of QFD as a quality improvement tool. A case study approach is used to test this framework, and quality issues were analyzed using the framework in a ceramic tile manufacturing company.

Findings – The results showed considerable improvements in the critical quality characteristics identified and sales rates, demonstrating the potential of QFD to be used in assessing and prioritizing areas of improvement, and converting them into measurable process or product requirements. Research limitations/implications …

In Vitro Cytocompatibility Of Antibacterial Levels Of Polymer Nitric Oxide Release, Rana Gbyli, Christina Zito, Kagya Amoako

Mechanical and Industrial Engineering Faculty Publications

Although the antibacterial property of nitric oxide (NO) has been well documented in gram positive and gram negative bacteria cultures, its cytotoxic effects are not completely clear. To limit potential in vivo cytotoxicity, our group recently investigated the effects of a range of NO fluxes on S. epidermidis and S. aureus to determine a minimum effective NO level. In this study, we report the antibacterial function of this minimum NO level also on gram negative Pseudomonas aeruginosa as well as its cytocompatibility effects on lung and kidney cells. Standardized bacterial cultures were treated with NO releasing PDMS substrates followed by …

A Project-Based Learning Approach In Teaching Simulation To Undergraduate And Graduate Students, Gokhan Egilmez, Dusan Sormaz, Ridvan Gedik

Engineering and Applied Science Education Faculty Publications

In this study, application of experiential learning into graduate and undergraduate curricula of a industrial system simulation course is presented. Simulation has been among the courses against which students feel uncomfortable or frightened due to heavy software use, prerequisite of probability, and statistics knowledge, and its application requirements. To minimize this fear and improve student’s understanding about the subject matters and have them develop ample skills to build complex models, a project-based learning approach is proposed and used in undergraduate and graduate teaching settings. To achieve the project-based learning goals, a 15-week curriculum is designed to have a balanced lecture …

Integrated E-Learning Modules For Developing An Entrepreneurial Mindset: Direct Assessment Of Student Learning, Maria-Isabel Carnasciali, Ronald S. Harichandran, Nadiye O. Erdil, Jean Nocito-Gobel, Cheryl Q. Li

Engineering and Applied Science Education Faculty Publications

In an effort to develop an entrepreneurial mindset in all our engineering and computer science students, the University of New Haven is embedding entrepreneurial concepts throughout the 4-year curricula in their majors. This is done with the use of several short e-learning modules developed by content experts. The modules are integrated into engineering and computer science courses by faculty who reinforce concepts through a related activity, project, or assignment. The e-learning modules, available online through course management systems, are self-paced and targeted at conceptual learning of 18 specific entrepreneurial topics. Using a flipped-classroom instructional model, students complete the modules outside …

A Pilot Program In Internet-Of-Things With University And Industry Collaboration: Introduction And Lessons Learned, Mohsen Sarraf, Bijan Karimi, Ali Golbazi

Engineering and Applied Science Education Faculty Publications

Internet-of-Things (IoT) is one of the most prominent technological eco-systems and an engine of growth with an estimated market size of $14 Trillion to $33 Trillion by 2025 (McKinsey Global Institute). The IoT eco-system uses well-established technologies in many fields; and it adds new and often challenging requirements on extant techniques. For example, many wireless schemes are or being redesigned to address battery life and cost of solution issues. At the same time, the industry needs to hire and retrain many technical personnel to address these issues and support this newly evolving eco-system in many different markets. These facts culminate …

A Gamification Approach For Experiential Education Of Inventory Control, Gokhan Egilmez, Ridvan Gedik

Engineering and Applied Science Education Faculty Publications

In this educational research project, game-based in-class and after-class learning activities are developed to teach selected inventory control strategies to undergraduate and graduate students. Students from Supply Chain Management and System Simulation courses are targeted, who are taught by different instructors. The activities include teaching the inventory control policies to students in a regular class setting, then providing an overview on a game developed on MS Excel. In the game, the lead time and customer demand variables are defined uncertain, and not given to students, which make the assignment an ill-structured problem. A 12-month planning and execution period is given …

Engineering and Applied Science Education Faculty Publications

In recent years, numerous engineering programs around the country have introduced curricular revisions and co-curricular activities to develop entrepreneurial skills in students. The primary motivation of these efforts is to graduate engineering students who can rapidly contribute to the economic growth of the nation through entrepreneurship and innovation. A precursor to launching startups or creating new products or services is the development of an entrepreneurial mindset. Efforts focused on developing an entrepreneurial mindset in engineering students through curricular and co-curricular activities are emerging from the many partner institutions of the Kern Entrepreneurial Engineering Network (KEEN). As these efforts strengthen, approaches …

Benchmarking Environmental Efficiency Of Ports Using Data Mining And Rdea: The Case Of A U.S. Container Ports, Yong Shin Park, N. Muhammad Aslaam Mohamed Abdul Ghani, Fesseha Gebremikael, Gokhan Egilmez

Mechanical and Industrial Engineering Faculty Publications

This study provides step-wise benchmarking practices of each port to enhance the environmental performance using a joint application of the data-mining technique referred to as Kohonen’s self-organizing map (KSOM) and recursive data envelopment analysis (RDEA) to address the limitation of the conventional data envelopment analysis. A sample of 20 container ports in the U.S.A. were selected, and data on input variables (number of quay crane, acres, berth and depth) and output variables (number of calls, throughput and deadweight tonnage, and CO2 emissions) are used for data analysis. Among the selected samples, eight container ports are found to be environmentally inefficient. …
