Product classification using anthropometric measurements leads to ergonomic product design and user satisfaction. We propose an effective artificial immune algorithm (AIA) to classify ergonomic products with multi-criteria anthropometric measurements and tune the AIA parameters with a full factorial experimental design approach. We demonstrate the applicability and efficacy of the proposed algorithm by considering the anthropometric measurements of the hand, developing an ergonomic computer mouse, and classifying consumers into three categories. The resulting classifications are compared with expert opinions to facilitate the conformity of the computer mouse to user requirements. 


Mindfulness-Based Safety: Increasing Attention To Task In Alberta’S Oil And Gas Drilling And Completions Operations, Darrah E.M. Wolfe 2016 University of Pennsylvania

Mindfulness-Based Safety: Increasing Attention To Task In Alberta’S Oil And Gas Drilling And Completions Operations, Darrah E.M. Wolfe

Master of Applied Positive Psychology (MAPP) Capstone Projects

With studies demonstrating mind-wandering to be associated with failure to perform monitoring procedural steps, a deficiency in being able to call information to mind, more false alarms, and a reduction in task performance, we cannot afford to continue to overlook the potential impact mind-wandering has on human behavior in high-risk environments within the Alberta oil and gas industry. This paper gives consideration to mindfulness-based interventions, a domain of positive psychology, for reducing the occurrence of mind-wandering and improving attention to a task. It is from a foundation of research explored in the literature reviews of mind-wandering and mindfulness, that I ...

Multi-Agent Distributed Optimization Via Inexact Consensus Admm, Tsung-Hui Chang, Mingyi Hong, Xiangfeng Wang 2016 National Taiwan University of Science and Technology

Multi-Agent Distributed Optimization Via Inexact Consensus Admm, Tsung-Hui Chang, Mingyi Hong, Xiangfeng Wang

Mingyi Hong

Multi-agent distributed consensus optimization problems arise in many signal processing applications. Recently, the alternating direction method of multipliers (ADMM) has been used for solving this family of problems. ADMM based distributed optimization method is shown to have faster convergence rate compared with classic methods based on consensus subgradient, but can be computationally expensive, especially for problems with complicated structures or large dimensions. In this paper, we propose lowcomplexity algorithms that can reduce the overall computational cost of consensus ADMM by an order of magnitude for certain large-scale problems. Central to the proposed algorithms is the use of an inexact step ...

Systematic Identification Of Coordination Gaps In Pediatric Care, Diana M. Prieto, Anil Kumar, Catherine L. Kothari, Cheryl Dickson

Frontiers in Public Health Services and Systems Research

In the United States, the status of coordination among pediatric care services is not well understood. Through the use of quality improvement (QI) techniques, coordination gaps were systematically identified in the interagency network of pediatric services in Kalamazoo MI. Gaps were found in transportation resources, follow-up procedures, awareness of services, interagency communication, insurance limitations, population behaviors, and resource utilization. This preliminary study reveals the need for (1) protocols for intra- and inter-agency communication, (2) mechanisms for easy and fast retrieval of pediatric resources, and (3) health information exchange.


A Bayesian-Influence Model For Error Probability Analysis Of Combine Operations In Harvesting, Yu Du, Michael C. Dorneich, Brian L. Steward, Cameron A. MacKenzie 2016 Iowa State University

A Bayesian-Influence Model For Error Probability Analysis Of Combine Operations In Harvesting, Yu Du, Michael C. Dorneich, Brian L. Steward, Cameron A. Mackenzie

Industrial and Manufacturing Systems Engineering Publications

Harvesting is one of the most important agricultural operations because it captures the value from the entire cropping season. In modern agriculture, grain harvesting has been mechanized through the combine harvester. A combine harvester enables highly productive crop harvesting. Combine harvesting performance depends on the highly variable skill of combine operators and associated operator error. An approach was developed to analyze the risk of the combine harvesting operation as it relates to operator error. Specifically, a risk analysis model was built based on a task analysis from operator interviews and estimates of the probability of operator error. This paper employs ...

Palmar and plantar grasp are the foremost primitive neonatal reflexes and functions. Persistence of these reflexes in infancy is a sign of evolving cerebral palsy. Our aims were to establish measurement feasibility in a clinical setting and to characterize changes in oxyhemoglobin (HbO) and deoxyhemoglobin (HbD) concentration in the bilateral frontoparietal cortex in unsedated neonates at the crib-side using functional near-infrared spectroscopy (fNIRS). We hypothesized that bilateral concentration changes will occur upon somatic central and peripheral somatic stimulation. Thirteen preterm neonates (five males) underwent time 1, and six (two males) returned for time 2 (mean PMA ¼ 41.6 and ...


Mechanisms And Solutions To The Brittle Solder Joint In Electroless Ni Plating, Xuan Wang, C. Key Chung 2016 California Polytechnic State University, San Luis Obispo

Mechanisms And Solutions To The Brittle Solder Joint In Electroless Ni Plating, Xuan Wang, C. Key Chung

Industrial and Manufacturing Engineering

Brittle solder joints in Electroless Ni electroless Pd immersion Au (ENEPIG) surface finishes are one of the key reliability issues in electronics assembly. Previous characterization of the reflow process has indicated that interfacial voids formed after solder reflow are responsible for the decreases in solder joint strength. However, the mechanisms behind the formation of these voids in the ENEPIG process remain unclear. In this paper, the interaction between various aspects of the ENEPIG process and solder joint strength were investigated. Surface roughness, morphology, and nano-pitting at the interface between electroless Pd and Ni-P were characterized. The size and density of ...

How User's Visualization Literacy Relates To Their Cognitive Traits, Jiming Yang, Sukwon Lee, Ji Soo Yi 2016 Purdue University

How User's Visualization Literacy Relates To Their Cognitive Traits, Jiming Yang, Sukwon Lee, Ji Soo Yi

The Summer Undergraduate Research Fellowship (SURF) Symposium

Researchers in the field of Information Visualization have suggested that users’ cognitive abilities would likely to affect their understanding of data visualizations and deeper exploration in the visualizations. However, the evidence is still scant to link between user’s visualization literacy and their cognitive traits. Thus, the research goal of this study is to explore how user’s visualization literacy and their cognitive traits are related. In particular, we focused on two cognitive traits: numeracy and need-for-cognition. In order to achieve the goal, first, we measured visualization literacy, numeracy, and need-for-cognition using existing instruments with 46 Amazon Mechanical Turk workers ...

Forecasting Employee Turnover In Large Organizations, Xiaojuan Zhu

Doctoral Dissertations

Researchers and human resource departments have focused on employee turnover for decades. This study developed a methodology forecasting employee turnover at organizational and departmental levels to shorten lead time for hiring employees. Various time series modeling techniques were used to identify optimal models for effective employee-turnover prediction based on a large U.S organization's 11-year monthly turnover data. A dynamic regression model with additive trend, seasonality, interventions, and a very important economic indicator efficiently predicted turnover. Another turnover model predicted both retirement and quitting, including early retirement incentives, demographics, and external economic indicators using the Cox proportional hazard model ...

Full Virtual Reality Vs. Integrated Virtual Reality Training In Welding, Richard T. Stone, Elease Mclaurin, Peihan Zhong, Kristopher Patrick Watts

Richard T. Stone Ph.D.

This study demonstrates that both fully virtual and virtual reality (VR) integrated into real-world training programs are appropriate for use in the domain of welding training, depending on the level of task difficulty. Performance differences were virtually indistinguishable between participants in the fully virtual and the integrated training group at the low and medium weld difficulty levels. At the highest level of difficulty, it became apparent that the VR system was no longer solely sufficient for training. This study also tracked the usage patterns for the visual aids used in the VR simulator. These optional aids were presented to the ...

Conditions Under Which Adjustability Lowers The Cost Of A Robust Linear Program, Ali Haddad-Sisakht, Sarah M. Ryan 2016 Iowa State University

Conditions Under Which Adjustability Lowers The Cost Of A Robust Linear Program, Ali Haddad-Sisakht, Sarah M. Ryan

Industrial and Manufacturing Systems Engineering Technical Reports and White Papers

The adjustable robust counterpart (ARC) of an uncertain linear program extends the robust counterpart (RC) by allowing some decision variables to adjust to the realizations of some uncertain parameters. The ARC may product a less conservative solution than the RC does but cases are known in which it does not. While the literature documents some examples of cost savings provided by adjustability (particularly affine adjustability), it is not straightforward to determine in advance whether they will materialize. The affine adjustable robust counterpart, while having a tractable structure, still may be much larger than the original problem. We establish conditions under ...
