A critical challenge for managerial effectiveness and competitive advantage in research and development (R and D) organizations is developing an appropriate structural configuration. However, in finding an appropriate structural configuration, R and D managers are faced with unprecedented levels of uncertainty, ambiguity, and accelerating complexity, coupled with demands for increased productivity. This paper develops a systems-based framework to support rigorous design, analysis, and transformation of the structure for R and D organizations. The framework development includes: (1) a review of the literature for the nature and role of the structure in R and D management; (2) setting of the R ...

Development Of An Unmanned Aerial System For Radiation Mapping In Nuclear Facilities, 2017 Purdue University
Development Of An Unmanned Aerial System For Radiation Mapping In Nuclear Facilities, Jackson Ball, Guangying Jiang, Robert Bean
The Summer Undergraduate Research Fellowship (SURF) Symposium
Efficiently planning a decontamination and decommissioning (D&D) operation at a nuclear facility requires detailed information on the conditions present. In the wake of a disaster, or just years of abandonment, a facility’s layout may have dramatically changed, making previous facility drawings unreliable, and radioactive particles may have been spread over the site, contaminating equipment and structures. Rather than tasking workers with mapping and characterizing the contamination, which can take days or weeks and poses a health and safety risk to the workers, mapping the site and locating contamination can be done remotely by an unmanned aerial vehicle (UAV ...

The implementation of the model is described, and results are presented both in methodological and technical terms. The goal of this article is to emphasize the need of new approaches to take into account hazards and accidents within socio-technical systems.
Decisions Management During Wildland Fires: Accidents Viewed As A Spatiotemporal Inadequacy, 2017 Embry-Riddle Aeronautical University
Decisions Management During Wildland Fires: Accidents Viewed As A Spatiotemporal Inadequacy, Karim Hardy
Extreme situations as wildland fires are a source of stress and pressure. In such events, decision-makers and incident commanders need to address a specific problem: how to manage time and resources to make meaningful decisions? Current models of accidents that exist to explain and manage catastrophes and disasters are inadequate and insufficient to deal with resources and time pressure due to uncertainty within a complex organization. Current incident response structures are incompetent and impotent to handle effectively a dynamic evolution of space and time in order to bring a situation back to stability adequately.
Modelling And Hazard Analysis For Contaminated Sediments Using Stamp Model, 2017 Mines ParisTech
Modelling And Hazard Analysis For Contaminated Sediments Using Stamp Model, Karim Hardy, Franck Guarnieri
Processes for remediation (removal of pollution or contaminants) of contaminated sediments have been very efficient. These technologies, which are particularly complex, call for a comprehensive approach to risk analysis which characterises all threats (to humans, equipment, local residents, the environment, etc.) . The STAMP accident model (Systems-Theoretic Accident Model and Processes) is an example of such a comprehensive approach, and it has been chosen to characterise the risks associated with Novosol (registered trademark), an innovative remediation process.

This article is a demonstration for a need of a new tool to take into account hazards and safety within socio-technical systems.
Flight Risk Management And Crew Reserve Optimization, 2017 University of Tennessee, Knoxville
Flight Risk Management And Crew Reserve Optimization, Ying Zhang
There are two key concerns in the development process of aviation. One is safety, and the other is cost. An airline running with high safety and low cost must be the most competitive one in the market. This work investigates two research efforts respectively relevant to these two concerns.
When building support of a real time Flight Risk Assessment and Mitigation System (FRAMS), a sequential multi-stage approach is developed. The whole risk management process is considered in order to improve the safety of each flight by integrating AHP and FTA technique to describe the framework of all levels of risks ...
Integrating Disparate Nuclear Data Sources For Improved Predictive Maintenance Modeling: Maintenance-Based Prognostics For Long-Term Equipment Operation, 2017 University of Tennessee, Knoxville
Integrating Disparate Nuclear Data Sources For Improved Predictive Maintenance Modeling: Maintenance-Based Prognostics For Long-Term Equipment Operation, Zachary Allen Welz
The United States (US) nuclear industry is one of the most heavily regulated businesses in the world, creating a culture of world-class design, operation, and maintenance. In an article published on modern maintenance technologies, Terrence OHanlon (past Chief Asset Manager for Reliabilityweb.com) stated, “world class companies often devote up to 50 percent of their entire maintenance resources to condition based monitoring and the planned work that is required as a result of the findings” . One would expect US nuclear power plants to constantly upgrade, improve, and expand their operations and maintenance departments and tactics. Since the early 1990s ...
Nuclear Weapons In A Changing Climate: Probability, Increasing Risks, And Perception, 2017 University of Nebraska - Lincoln
Nuclear Weapons In A Changing Climate: Probability, Increasing Risks, And Perception, Adam Liska, Tyler R. White, Eric Holley, Robert J. Oglesby
Adam Liska Papers
Many people tend to think that the outcome of any nuclear weapons use today will result in an escalatory situation with apocalyptic outcomes for the countries involved. Yet many factors are increasing the probability of the limited use of nuclear weapons (e.g., 1 to 20 warheads) in a range of conflict scenarios. Previous atmospheric model simulations of regional nuclear conflicts employing many relatively small bombs have been estimated to cause a global “nuclear autumn,” with great reductions in agricultural productivity, stratospheric ozone loss, and spread of hazardous radioactive fallout. The totality of these effects would result in widespread ...
Top-Down Construction Cost Estimating Model Using An Artificial Neural Network, 2017 Iowa State University
Top-Down Construction Cost Estimating Model Using An Artificial Neural Network, Douglas D. Gransberg, H. David Jeong, Ilker Karaca, Brendon Gardner
This report contains the information and background on top-down cost estimating using artificial neural networks (ANN)_to enhance the accuracy of MDT early estimates of construction costs. Upon conducting an extensive review of MDT’s budgeting and cost estimating efforts, and following a survey of agency experts on the identification of the most salient project attributes with the dual-objectives of low effort and high accuracy, a rational method for top-down variable selection is proposed. Selected variables were further tested in their explanatory power of construction costs through the application of two cost estimating methodologies—multiple regression and artificial neural network ...
Capturing Cognitive Fingerprints From Keystroke Dynamics, 2017 Iowa State University
Capturing Cognitive Fingerprints From Keystroke Dynamics, J. Morris Chang, Chi-Chen Fang, Kuan-Hsing Ho, Norene Kelly, Pei-Yuan Wu, Yixiao Ding, Chris Chu, Stephen B. Gilbert, Amed E. Kamal, Sun-Yuan Kung
Conventional authentication systems identify a user only at the entry point. Keystroke dynamics can continuously authenticate users by their typing rhythms without extra devices. This article presents a new feature called cognitive typing rhythm (CTR) to continuously verify the identities of computer users. Two machine techniques, SVM and KRR, have been developed for the system. The best results from experiments conducted with 1,977 users show a false-rejection rate of 0.7 percent and a false-acceptance rate of 5.5 percent. CTR therefore constitutes a cognitive fingerprint for continuous. Its effectiveness has been verified through a large-scale dataset. This article ...
Comparison Of Intrusive And Non-Intrusive Methods For Corrosion Monitoring Of Fuel Processing Systems, 2017 California Polytechnic State University, San Luis Obispo
Comparison Of Intrusive And Non-Intrusive Methods For Corrosion Monitoring Of Fuel Processing Systems, Armando Jacob Espinoza, Thomas Conner Field
This presentation contains an assessment of the best overall corrosion monitoring device, intrusive or non-intrusive, for use in the petrochemical industry. Corrosion in the petrochemical industry is a large issue because it causes a deterioration of pipe integrity in fuel processing systems. A reduction of pipe wall integrity due to corrosion could result in a leak or an explosion of fuel processing lines since those systems function at high pressures. The use of corrosion monitoring systems in the petrochemical industry helps to detect early signs of corrosion prior to failure so that proper maintenance can be performed to prevent catastrophe ...
Motion Dynamics Of Dropped Cylindrical Objects, 2017 University of New Orleans
Motion Dynamics Of Dropped Cylindrical Objects, Gong Xiang
University of New Orleans Theses and Dissertations
Dropped objects are among the top ten causes of fatalities and serious injuries in the oil and gas industry. Objects may be dropped during lifting or any other offshore operation. Concerns of health, safety, and the environment (HSE) as well as possible damages to structures require the prediction of where and how a dropped object moves underwater. This study of dropped objects is subdivided into three parts. In the first part, the experimental and simulated results published by Aanesland (1987) have been successfully reproduced and validated based on a two-dimensional (2D) theory for a dropped drilling pipe model. A new ...

Who R U? Identity Theft And Unl Students, Marcia L. Dority Baker, Cheryl O'Dell
Publications from Information Technology Services
How can academic institutions help educate their students about the risks of identity theft? Or teach students to better understand how one’s online presence can hold so much joy and angst? For one campus, the University of Nebraska–Lincoln, the opportunity came from a middle school teacher engaging his students in a future problem-solving activity. UNL had the opportunity to create a 45-minute presentation on identity theft for local public school students who would be spending the day on campus researching this topic.
While preparing the presentation, we realized a top 10 list on identity theft for UNL students ...
Cost Versus Risk: The Policy Of Nuclear Weapon Maintenance Of Tritium Based Limited Life Components, 2017 Air Force Institute of Technology
Cost Versus Risk: The Policy Of Nuclear Weapon Maintenance Of Tritium Based Limited Life Components, Michael P. Mason
Theses and Dissertations
This research develops a method to measure the cost to society of current maintenance policy for the exchange of tritium based limited life components within nuclear weapons. The incentives for the Department of Energy and Department of Defense which causes either a substantial cost or substantial risk to be accepted by either Department. A simulation model is created to measure the current policy and compare it to different policies in order to recommend a policy that would minimize the cost to society. The measurement of the cost to society will offer decision makers insight into the ramifications of their decisions.
Methods For Incorporating Ecological Impacts With Climate Uncertainty To Support Robust Flood Management Decision-Making, 2017 University of Massachusetts - Amherst
Methods For Incorporating Ecological Impacts With Climate Uncertainty To Support Robust Flood Management Decision-Making, Caitlin M. Spence
Modern and historic flood risk management involves accommodating multiple sources of sources of uncertainty and potential impacts across a broad range of interrelated sectors. Sources of uncertainty that affect planning include internal climate variability, anthropogenic changes such as land use and system performance expectations, and more recently changes in climatology that affect the resources supporting the system. Flood management systems potentially impact human settlements within and beyond the systems’ scope of planning, local weather patterns, and associated ecological systems. Federal guidelines across nations have called for greater consideration of uncertainty and impacts of water resources planning projects, but methods for ...

Optimum Injury And Illness Prevention Cost For U.S. Construction Projects, 2017 Central Washington University
Optimum Injury And Illness Prevention Cost For U.S. Construction Projects, Dominic Klyve, Sathyanarayanan Rajendran, Morgan Bliss
Mathematics Faculty Scholarship
Worker injuries and illnesses can affect the profitability of an organization. Regardless of the regulatory requirements for safety and health, many organizations prefer to see positive returns (i.e., better safety metric performance) on their safety investments (i.e., project costs associated with injury and illness prevention programs). Understanding the relationship between costs associated with an injury and illness prevention program of a construction project and project safety performance is critical to the future success of construction organizations in the United States. In evaluating this relationship, the authors’ goal was to identify an equilibrium point of injury and illness prevention ...
Built-In Bicycle Rack For Cars, 2017 Central Washington University
Built-In Bicycle Rack For Cars, Scott A. Hansberry
All Undergraduate Projects
Transporting a bicycle after riding somewhere and then needing to be pickup can be problematic. Bicycles will not fit in most vehicles without removing components. There is also the risk of damaging the inside of the vehicle. Expecting everyone to have a bike rack for their vehicle is unrealistic because the bike rack could be considered unappealing visually, take up to much space in the trunk, or limit the vehicle owner’s access to the trunk. The solution to this problem is a bike rack that mounts onto your car and then mounts your bike onto the rack. Most people ...
