The paper implements a modification of a fuzzy neural network, which is suitable for predictive control purposes. Adaptation of a multidimensional programmable controller based on a neural algorithm for the back propagation of forecasting errors is proposed, as well as neural parametric identification of a fuzzy mathematical model of complex technological processes and production based on experimental data and expert estimates.


Examples Of Gibsonian Affordances In Legged Robotics Research Using An Empirical, Generative Framework, Sonia F. Roberts, Daniel E. Koditschek, Lisa J. Miracchi 2020 University of Pennsylvania

Examples Of Gibsonian Affordances In Legged Robotics Research Using An Empirical, Generative Framework, Sonia F. Roberts, Daniel E. Koditschek, Lisa J. Miracchi

Departmental Papers (ESE)

Evidence from empirical literature suggests that explainable complex behaviors can be built from structured compositions of explainable component behaviors with known properties. Such component behaviors can be built to directly perceive and exploit affordances. Using six examples of recent research in legged robot locomotion, we suggest that robots can be programmed to effectively exploit affordances without developing explicit internal models of them. We use a generative framework to discuss the examples, because it helps us to separate—and thus clarify the relationship between—description of affordance exploitation from description of the internal representations used by the robot in that exploitation ...

Understanding Rural Water Services As A Complex System: An Assessment Of Key Factors As Potential Leverage Points For Improved Service Sustainability, Nicholas Valcourt, Jeffrey P. Walters, Amy Javernick-Will, Karl Linden, Betelhem Hailegiorgis

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Rural water supply services worldwide consistently fail to deliver full public health impacts as intended due to a low service sustainability. This failure is increasingly attributed to weak local systems composed of social, financial and environmental factors. Current approaches in the water, sanitation and hygiene (WASH) sector for understanding and improving these systems typically focus on the strength and capacity of these factors, but not the interactions between them. We contend that these approaches overlook the inherent complexity and context-specific nature of each local system. To assess this complexity, we conducted four participatory factor mapping workshops with local stakeholders across ...


Modulation Of Robot Orientation Via Leg-Obstacle Contact Positions, Divya Ramesh, Anmol Kathail, Daniel E. Koditschek, Feifei Qian 2020 University of Pennsylvania

Modulation Of Robot Orientation Via Leg-Obstacle Contact Positions, Divya Ramesh, Anmol Kathail, Daniel E. Koditschek, Feifei Qian

Departmental Papers (ESE)

We study a quadrupedal robot traversing a structured (i.e., periodically spaced) obstacle field driven by an open-loop quasi-static trotting walk. Despite complex, repeated collisions and slippage between robot legs and obstacles, the robot’s horizontal plane body orientation (yaw) trajectory can converge in the absence of any body level feedback to stable steady state patterns. We classify these patterns into a series of “types” ranging from stable locked equilibria, to stable periodic oscillations, to unstable or mixed period oscillations. We observe that the stable equilibria can bifurcate to stable periodic oscillations and then to mixed period oscillations as the ...

System Approaches To Water, Sanitation, And Hygiene: A Systematic Literature Review, Nicholas Valcourt, Amy Javernick-Will, Jeffrey P. Walters, Karl Linden 2020 University of Colorado Boulder

System Approaches To Water, Sanitation, And Hygiene: A Systematic Literature Review, Nicholas Valcourt, Amy Javernick-Will, Jeffrey P. Walters, Karl Linden

Faculty Publications - Biomedical, Mechanical, and Civil Engineering

Endemic issues of sustainability in the water, sanitation, and hygiene (WASH) sector have led to the rapid expansion of ‘system approaches’ for assessing the multitude of interconnected factors that affect WASH outcomes. However, the sector lacks a systematic analysis and characterization of the knowledge base for systems approaches, in particular how and where they are being implemented and what outcomes have resulted from their application. To address this need, we conducted a wide-ranging systematic literature review of systems approaches for WASH across peer-reviewed, grey, and organizational literature. Our results show a myriad of methods, scopes, and applications within the sector ...


A Programmably Compliant Origami Mechanism For Dynamically Dexterous Robots, Wei-Hsi Chen, Shivangi Mishra, Yuchong Gao, Young-Joo Lee, Daniel Koditschek, Shu Yang, Cynthia R. Sung 2020 University of Pennsylvania

A Programmably Compliant Origami Mechanism For Dynamically Dexterous Robots, Wei-Hsi Chen, Shivangi Mishra, Yuchong Gao, Young-Joo Lee, Daniel Koditschek, Shu Yang, Cynthia R. Sung

Departmental Papers (ESE)

We present an approach to overcoming challenges in dynamical dexterity for robots through programmably compliant origami mechanisms. Our work leverages a one-parameter family of flat sheet crease patterns that folds into origami bellows, whose axial compliance can be tuned to select desired stiffness. Concentrically arranged cylinder pairs reliably manifest additive stiffness, extending the programmable range by nearly an order of magnitude and achieving bulk axial stiffness spanning 200–1500 N/m using 8 mil thick polyester-coated paper. Accordingly, we design origami energy-storing springs with a stiffness of 1035 N/m each and incorporate them into a three degree-of-freedom (DOF) tendon-driven ...

Uas For Public Safety Operations: A Comparison Of Uas Point Clouds To Terrestrial Lidar Point Cloud Data Using A Faro Scanner, Joseph S. Cerreta, Scott S. Burgess, Jeremy Coleman

International Journal of Aviation, Aeronautics, and Aerospace

Unmanned Aircraft Systems (UAS) can be useful tools for public safety agencies during crime or vehicle accident scene investigations if it can provide value to the resource-constrained agency. The speed of data collection, while minimizing first responder risk, while sustaining an acceptable level of accuracy and precision compared to other tools is where the agency may find value. During a recent homicide investigation in Florida, a UAS provided saved 81% in law enforcement labor hours with an acceptable level of accuracy compared to traditional methods. The purpose of this research was to compare UAS to determine if there were differences ...


Achieving Consistency With Cutting Planes, Danial Davarnia, Atefeh Rajabalizadeh, John Hooker 2020 Iowa State University

Achieving Consistency With Cutting Planes, Danial Davarnia, Atefeh Rajabalizadeh, John Hooker

Industrial and Manufacturing Systems Engineering Publications

Cutting planes accelerate branch-and-bound search primarily by cutting off fractional solutions of the linearprogramming (LP) relaxation, resulting in tighter bounds for pruning the search tree. Yet cutting planes canalso reduce backtracking by excluding inconsistent partial assignments that occur in the course of branching.A partial assignment is inconsistent with a constraint set when it cannot be extended to a full feasibleassignment. The constraint programming community has studied consistency extensively and used it as aneffective tool for the reduction of backtracking. We extend this approach to integer programming (IP) bydefining concepts of consistency that are useful in a branch-and-bound context. We ...


Forecasting Corn Yield With Machine Learning Ensembles, Mohsen Shahhosseini, Guiping Hu, Sotirios Archontoulis 2020 Iowa State University

Forecasting Corn Yield With Machine Learning Ensembles, Mohsen Shahhosseini, Guiping Hu, Sotirios Archontoulis

Industrial and Manufacturing Systems Engineering Publications

The emerge of new technologies to synthesize and analyze big data with high-performance computing, has increased our capacity to more accurately predict crop yields. Recent research has shown that Machine learning (ML) can provide reasonable predictions, faster, and with higher flexibility compared to simulation crop modeling. The earlier the prediction during the growing season the better, but this has not been thoroughly investigated as previous studies considered all data available to predict yields. This paper provides a machine learning based framework to forecast corn yields in three US Corn Belt states (Illinois, Indiana, and Iowa) considering complete and partial in-season ...

Teleporting Through Virtual Environments: Effects Of Path Scale And Environment Scale On Spatial Updating, Jonathan W. Kelly, Alec G. Ostrander, Alex F. Lim, Lucia A. Cherep, Stephen B. Gilbert

Industrial and Manufacturing Systems Engineering Publications

Virtual reality systems typically allow users to physically walk and turn, but virtual environments (VEs) often exceed the available walking space. Teleporting has become a common user interface, whereby the user aims a laser pointer to indicate the desired location, and sometimes orientation, in the VE before being transported without self-motion cues. This study evaluated the influence of rotational self-motion cues on spatial updating performance when teleporting, and whether the importance of rotational cues varies across movement scale and environment scale. Participants performed a triangle completion task by teleporting along two outbound path legs before pointing to the unmarked path ...


Complementarity‐Based Selection Strategy For Genomic Selection, Saba Moeinizade, Megan Wellner, Guiping Hu, Lizhi Wang 2020 Iowa State University

Complementarity‐Based Selection Strategy For Genomic Selection, Saba Moeinizade, Megan Wellner, Guiping Hu, Lizhi Wang

Industrial and Manufacturing Systems Engineering Publications

Genomic selection is a technique that breeders use to select plant or animal individuals to mate and produce new generations of species. The conventional selection method is to select individuals that are either observed or predicted to be the best based on the assumption that parents with better phenotypes will produce better offspring. A major limitation of this method is its focus on the short‐term genetic gains at the cost of genetic diversity and long‐term growth potential. Recently, several new genomic selection methods were proposed to maximize the long‐term potential. Along this research direction, we propose a ...

Industrial and Manufacturing Systems Engineering Publications

Open data standards (e.g. LandXML, TransXML, CityGML) are a key to addressing the interoperability issue in exchanging civil information modeling (CIM) data throughout the project life-cycle. Since these schemas include rich sets of data types covering a wide range of assets and disciplines, model view definitions (MVDs) which define subsets of a schema are required to specify what types of data to be shared in accordance with a specific exchange scenario. The traditional procedure for generating and implementing MVDs is time-consuming and laborious as entities and attributes relevant to a particular data exchange context are manually identified by domain ...


Rinse Tank Salinity Automation, George Pahoundis 2020 The University of Akron

Rinse Tank Salinity Automation, George Pahoundis

Williams Honors College, Honors Research Projects

Manufacturing processes are often consisted of many different processes and sub-processes. Each of these carries its own level of importance and impact to the overall picture. In this particular sub-process, salt is rinsed from a product via a rinse tank: a tank whose salinity may not exceed a certain level and whose temperature must not fall below a certain level. This setting is a prime opportunity to implement an automated control system to allow these parameters to be met with upmost efficiency. With potential savings in excess of $20,000 per year and an estimated payback period of 8 weeks ...

Numerical Analyses And Integration Of Split Lot Sizing Using Lean Benchmark Model For Small Lot Manufacturing In High Mix Low Volume Production, Omkar Bhosale

Theses and Dissertations--Manufacturing Systems Engineering

As the global demand for automobiles has increased rapidly over the last fifty years, customers have become more particular about the characteristics of the autos they want. This change in demand, in part has pushed manufacturing to become more flexible and created a demand for alternative, more efficient processes like the High Mix Low Volume (HMLV) production of vehicles. During HMLV, manufacturers create production lot sizes and schedule to synchronize the production processes to meet customer demand on time. The demand for the automobile parts may not be uniform or parts may not be consumed by the customer immediately, Due ...

Individual Differences In Teleporting Through Virtual Environments: A Latent Profile Analysis, Lucia A. Cherep, Alex F. Lim, Jonathan W. Kelly, Anthony Miller, Stephen B. Gilbert 2020 Iowa State University

Individual Differences In Teleporting Through Virtual Environments: A Latent Profile Analysis, Lucia A. Cherep, Alex F. Lim, Jonathan W. Kelly, Anthony Miller, Stephen B. Gilbert

Industrial and Manufacturing Systems Engineering Conference Proceedings and Posters

Teleportation in virtual reality (VR) affords the ability to explore beyond the physical space. Previous work has demonstrated that this interface comes at a spatial cognitive cost – though, upon closer inspection, not everyone appears similarly affected. A latent profile analysis identified three groups that significantly differed on spatial updating performance and follow-up analyses showed significant differences in objective measures of spatial ability (e.g., mental rotation and perspective-taking). These results suggest that there are individual differences in domains of spatial cognition that are related to how well a user may keep track of his or her location while teleporting in ...
