Effect Of Ultra-High Pulse Frequency On The Resolution In The Electrochemical Deposition Of Nickel, Abishek Balsamy Kamaraj, Natalie Reed, Murali Sundaram Jan 2021

Effect Of Ultra-High Pulse Frequency On The Resolution In The Electrochemical Deposition Of Nickel, Abishek Balsamy Kamaraj, Natalie Reed, Murali Sundaram

Industrial & Manufacturing Engineering Presentations And Conference Materials

Using localized electrochemical deposition (LECD) as a mask-less direct writing methodology, metal shapes are printed. The electrochemical double-layer capacitance at ultra-high frequencies is hypothesized to cause a localized deposition and the effect of pulse frequency on the current density is modeled to predict the deposition resolution and rate of deposition. Experimental results confirm that the deposition resolution and efficiency of the LECD process increase with the increase of pulse frequency. Deposition resolution 80% smaller than the tool diameter is feasible in the LECD of nickel used with a ø 250 μm tool at 1 MHz pulsed power.


Optimizing Production Schedule With Energy Consumption And Demand Charges In Parallel Machine Setting, Farnaz Ghazi Nezami, Mojtaba Heydar, Regina Berretta Dec 2017

Optimizing Production Schedule With Energy Consumption And Demand Charges In Parallel Machine Setting, Farnaz Ghazi Nezami, Mojtaba Heydar, Regina Berretta

Industrial & Manufacturing Engineering Presentations And Conference Materials

Environmental sustainability concerns, along with the growing need for electricity and associated costs, make energy-cost reduction an inevitable decision-making criterion in production scheduling. In this research, we study the problem of production scheduling on nonidentical parallel machines with machine-dependent processing times and known job release dates to minimize total completion time and energy costs. The energy costs in this study include demand and consumption charges. We present a mixed-integer nonlinear model to formulate the problem. The model is then linearized and its performance is tested through numerical experiments.

Developing Entrepreneurial Mindset In Industrial Engineering Classes: A Case Study, Farnaz Ghazi Nezami, Massoud Tavakoli, Mohammad Torfeh Jun 2016

Developing Entrepreneurial Mindset In Industrial Engineering Classes: A Case Study, Farnaz Ghazi Nezami, Massoud Tavakoli, Mohammad Torfeh

Industrial & Manufacturing Engineering Presentations And Conference Materials

Instilling entrepreneurial mindset among engineering students is one of the challenges in engineering education. This paper presents the efforts to improve a core undergraduate industrial engineering course, Designing Value in Supply Chain, to infuse entrepreneurial thinking among students using an internally funded grant by Kern Entrepreneurial Engineering Network (KEEN). For this purpose, three new course modules are designed and their effectiveness on student learning is evaluated. This course is ideal for establishing entrepreneurially minded learning (EML) as a systematic approach is required for managing the chain of supply, especially since the impacts of the decisions are not isolated and will …


Active Learning In Supply Chain Management Course, Farnaz Ghazi-Nezami, Mehmet Bayram Yildirim Jun 2015

Active Learning In Supply Chain Management Course, Farnaz Ghazi-Nezami, Mehmet Bayram Yildirim

Industrial & Manufacturing Engineering Presentations And Conference Materials

Active Learning in the Supply Chain Management Course. This paper presents a new active learning approach implemented in the Supply ChainManagement (SCM) course in the Industrial and Manufacturing Engineering Department.Previously, in this course the fundamentals of supply chain and logistics, drivers of supply chainperformance and analytical tools necessary to develop solutions for a variety of SCM and designproblems were mainly covered through class lectures and case study discussions. In the past fewyears, due to the growth in the needs of the organizations to “Lean” principles, the course wasmodified to satisfy this requirement more efficiently. For this purpose a new hands …


A Multi-Server Markovian Queueing Model With Primary And Secondary Services, Valentina Klimenok, Srinivas R. Chakravarthy, Alexander Dudin Jan 2005

A Multi-Server Markovian Queueing Model With Primary And Secondary Services, Valentina Klimenok, Srinivas R. Chakravarthy, Alexander Dudin

Industrial & Manufacturing Engineering Presentations And Conference Materials

We study a multi-server queueing model in which the arrivals occur according to a Markovian arrival process. An arriving customer either (a) is lost due to all main servers being busy; or (b) enters into service with one of the main servers and leaves the system (as a satisfied primary customer); (c) enters into a service with one of the main servers, gets service in self-service mode, and is impatient to get a final service with one of the main servers, may leave the system (as a dissatisfied secondary customer); or (d) enters into service with one of the main …


How To Increase The Ability Of A Student To Learn, Srinivas R. Chakravarthy Jun 2004

How To Increase The Ability Of A Student To Learn, Srinivas R. Chakravarthy

Industrial & Manufacturing Engineering Presentations And Conference Materials

An instructor is always challenged when covering the materials in a course (according to the syllabus) and at the same time making sure that all students have the opportunity to learn and understand the materials presented in the classroom. In this paper we will present some ideas and tools that enable one to try to achieve a balance. These are based on the author’s experience and perspective in teaching deterministic and stochastic operations research courses.
