Rapid Tagging And Reporting For Functional Language Extraction In Scientific Articles, Mahdi Ramezani, Vijay K. Kalivarapu, Stephen B. Gilbert, Sarah R. Huffman, Elena Cotos, Annette M. O'Connor Dec 2017

Rapid Tagging And Reporting For Functional Language Extraction In Scientific Articles, Mahdi Ramezani, Vijay K. Kalivarapu, Stephen B. Gilbert, Sarah R. Huffman, Elena Cotos, Annette M. O'Connor

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

This paper describes the development of a web-based application for tagging scientific articles, in part to create machine learning training datasets for automated functional language identification and extraction (AFLEX). The initial intent for this work was to provide a new member of the ecosystem of tools that facilitate the structured automation of systematic reviews, an area of work that typically requires critical analysis of multiple research studies and provides an exhaustive summary of literature related to a research question. However, the tool’s modular interface allows use across disciplines. A user may upload PDF or text documents and quickly tag ...


Robust Optimization Vs. Stochastic Programming Incorporating Risk Measures For Unit Commitment With Uncertain Variable Renewable Generation, Narges Kazemzadeh, Sarah M. Ryan, Mahdi Hamzeei Dec 2017

Robust Optimization Vs. Stochastic Programming Incorporating Risk Measures For Unit Commitment With Uncertain Variable Renewable Generation, Narges Kazemzadeh, Sarah M. Ryan, Mahdi Hamzeei

Industrial and Manufacturing Systems Engineering Publications

Unit commitment seeks the most cost effective generator commitment schedule for an electric power system to meet net load, defined as the difference between the load and the output of renewable generation, while satisfying the operational constraints on transmission system and generation resources. Stochastic programming and robust optimization are the most widely studied approaches for unit commitment under net load uncertainty. We incorporate risk considerations in these approaches and investigate their comparative performance for a multi-bus power system in terms of economic efficiency as well as the risk associated with the commitment decisions. We explicitly account for risk, via Conditional ...


A Key Components-Based Heuristic Modular Product Design Approach To Reduce Product Assembly Cost, Junfeng Ma, Gul E. Okudan-Kremer, Mian Li Dec 2017

A Key Components-Based Heuristic Modular Product Design Approach To Reduce Product Assembly Cost, Junfeng Ma, Gul E. Okudan-Kremer, Mian Li

Industrial and Manufacturing Systems Engineering Publications

Nowadays, increasing awareness of sustainability and varied customer requirements have driven manufacturers to reconsider product development starting from the design phase. As one response to these concerns, modular product design (MPD) has attracted significant attention. Since the architecture of a product or a system can have implications on its assembly cost, MPD and product assembly should be investigated jointly. In this paper, a heuristic clustering algorithm with key components emphasis that will reduce assembly cost is offered to group components into modules. Key product/system components are those that afford competitiveness to a company. An MPD method that can decrease ...

Current in-house water cooler systems use pre-filtered water that is bought by the gallon. Currently, the jugs of filtered water used in these water cooler systems are picked up & exchanged for full jugs of filtered water as a paid service from a 3rd-party company. As an outsourced service, this current setup creates additional, unnecessary costs, as well as logistical factors to be dealt with such as scheduling refill delivery&planning for storage of the required on-hand stock of bottles.

CVI LLC trials have shown that corn can be planted with periodic skipped rows without yield loss, and in some cases, yields can be increased. Companion and cover crops planted in skipped rows are one way in which these unplanted rows can be beneficial. If no yield loss is realized when skipping a row at pre-determined intervals, the skipped row crops can be used to help build the soil and provide additional nutrients in-season. Analysis will be done to make a recommendation on how to best utilize skipped rows in corn fields.

The Armed Robotic Control for Training in Civilian Law Enforcement, or ARCTiC LawE, is an upper-body exoskeleton designed to assist civilian, military, and law enforcement personnel in accurate, precise, and reliable handgun techniques. This exoskeleton training utilizes a laser-based handgun with similar dimensions, trigger pull, and break action to a Glock® 19 pistol, common to both public and private security sectors. The paper aims to train and test subjects with no handgun training/experience both with and without the ARCTiC LawE and compare the results of accuracy, precision, and speed. Ultimately, the exoskeleton greatly impacts sensory motor learning, and the ...


A Comprehensive End-Of-Life Strategy Decision Making Approach To Handle Uncertainty In The Product Design Stage, Junfeng Ma, Gul E. Okudan-Kremer, Charles David Ray Nov 2017

A Comprehensive End-Of-Life Strategy Decision Making Approach To Handle Uncertainty In The Product Design Stage, Junfeng Ma, Gul E. Okudan-Kremer, Charles David Ray

Industrial and Manufacturing Systems Engineering Publications

This study employs fuzzy logic to evaluate uncertain component end-of-life (EOL) options in the design stage. Determining EOL strategies during the product design stage can be complex. For example, EOL strategies for retired bicycle components are various and may change with geographic location. Thus, adopting fixed EOL strategies in the product design stage may not always be appropriate; the element of uncertainty should be considered. Limited research has examined uncertainty of EOL strategies during the design stage. Moreover, the evaluation of EOL strategies in a comprehensive manner has not been shown in a realistic case study. These facts motivate this ...

High-Throughput Search For Caloric Materials: The Caloricool Approach, Nikolai A. Zarkevich, Duane D. Johnson, Vitalij K. Pecharsky

Ames Laboratory Accepted Manuscripts

The high-throughput search paradigm adopted by the newly established caloric materials consortium – CaloriCool® – with the goal to substantially accelerate discovery and design of novel caloric materials is briefly discussed. We begin with describing material selection criteria based on known properties, which are then followed by heuristic fast estimates, ab-initio calculations and measurements, all of which has been implemented in a set of automated computational tools. We also demonstrate how theoretical and computational methods serve as a guide for experimental efforts by considering a representative example from the field of magnetocaloric materials
