Selecting Attributes, Rules, And Membership Functions For Fuzzy Sos Architecture Evaluation, Louis Pape, Siddhartha Agarwal, Cihan H. Dagli
Selecting Attributes, Rules, And Membership Functions For Fuzzy Sos Architecture Evaluation, Louis Pape, Siddhartha Agarwal, Cihan H. Dagli
Engineering Management and Systems Engineering Faculty Research & Creative Works
The development of the FILA-SoS meta-architecture approach to acknowledged systems of systems (SoS) analysis allows a relatively unbiased method for exploring a potential SoS architecture space. This paper delves more deeply into the process of building the lists of desirable fuzzy attributes of a SoS, developing rules for combining attribute values to an overall assessment, and discovering membership function shapes that work well. A wide range of options exist for all the individual elements of SoS assessment. Some recommendations for finding an appropriate combination for the adjustable parameters of fuzzy assessment models through random architecture chromosome testing and iteration are …

Substantial dialogue exists regarding the needs of the engineering profession and the changes in engineering education necessary to meet them. Important to this change is an increased emphasis on the professional competencies as identified by the Washington Accord and the ABET professional skills for engineering graduates and how to educate for them. This paper will explore the potential for a project based learning engineering curriculum model to meet this need. It will summarize a newly developed upper-division undergraduate project-based learning (PBL) engineering program in the U.S. engineering educational system and its approach to professional competency development. Based on the ABET …
Multiple-Choice Testing Using Immediate Feedback-Assessment Technique (If At®) Forms: Second-Chance Guessing Vs. Second-Chance Learning?, Jeremy D. Merrel, Pier F. Cirillo, Pauline M. Schwartz, Jeffrey Webb
Multiple-Choice Testing Using Immediate Feedback-Assessment Technique (If At®) Forms: Second-Chance Guessing Vs. Second-Chance Learning?, Jeremy D. Merrel, Pier F. Cirillo, Pauline M. Schwartz, Jeffrey Webb
Chemistry and Chemical Engineering Faculty Publications
Multiple choice testing is a common but often ineffective method for evaluating learning. A newer approach, however, using Immediate Feedback Assessment Technique (IF AT®, Epstein Educational Enterprise, Inc.) forms, offers several advantages. In particular, a student learns immediately if his or her answer is correct and, in the case of an incorrect answer, has an opportunity to provide a second response and receive partial credit for a correct second attempt. For a multiple choice question with five possible answers, the IF AT® form covers spaces labeled A through E with a thin opaque film; when the film is scratched away, …

A Review Of Probabilistic Methods Of Assessment Of Load Effects In Bridges, Eugene J. Obrien, F Schmidt, Donya Hajializadeh, X-Y Zhou, Bernard Enright, Colin C. Caprani, Simon Wilson, Emma Sheils
Articles
This paper reviews a range of statistical approaches to illustrate the influence of data quality and quantity on the probabilistic modelling of traffic load effects. It also aims to demonstrate the importance of long-run simulations in calculating characteristic traffic load effects. The popular methods of Peaks Over Threshold and Generalized Extreme Value are considered but also other methods including the Box-Cox approach, fitting to a Normal distribution and the Rice formula. For these five methods, curves are fitted to the tails of the daily maximum data. Bayesian Updating and Predictive Likelihood are also assessed, which require the entire data for …
A Phantom Assessment Of Achievable Contouring Concordance Across Multiple Treatment Planning Systems, Elise M. Pogson, Jarrad Begg, Michael Jameson, Claire Dempsey, Drew Latty, Vikneswary Batumalai, Andrew Lim, Kankean Kandasamy, Peter E. Metcalfe, Lois C. Holloway

Faculty of Engineering and Information Sciences - Papers: Part A
In this paper, the highest level of inter- and intra-observer conformity achievable with different treatment planning systems (TPSs), contouring tools, shapes, and sites have been established for metrics including the Dice similarity coefficient (DICE) and Hausdorff Distance. High conformity values, e.g. DICEBreast_Shape = 0.99 ± 0.01, were achieved. Decreasing image resolution decreased contouring conformity.

An increasing population of university programs and quantity of curricular content focused on entrepreneurship poses both enormous opportunities for student growth, and numerous practical challenges. Prior work has largely focused on pre-post assessment of student learning, shifts in‘mindset’, activity effectiveness, mapping of student outcomes, and implications of student learning on career success. A baseline of freshman student attitudes towards entrepreneurship,outside of specifically focused entrepreneurial leaning, has significant potential to identify and inform programming in entrepreneurship, as well as general curriculums and pedagogy. An improved understanding of student’s constructive and cognitive influences in entrepreneurial education will serve to better inform the …

Although wide bore computed tomography (CT) scanners provide increased space for patients, the scan field of view (sFOV) remains considerably smaller than the bore size. Consequently, patient anatomy which spans beyond the sFOV is truncated and the information is lost. As a solution, some manufacturers provide the capacity to reconstruct CT images from a partial dataset at an extended field of view (eFOV). To assess spatial distortion within this eFOV three phantoms were considered a 30 x 30 x 20 cm3 slab of solid water, the Gammex electron density CT phantom and a female anthropomorphic phantom. For each phantom, …

Voltage unbalance (VU) management of power systems requires the development of well researched engineering practices to maintain acceptable VU levels while utilising the total VU absorption capacity of the power system. In this regard, IEC/TR 61000-3-13:2008 prescribes a VU emission allocation methodology based on a stochastic approach which uses a general summation law in order to aggregate numerous sources of unbalance to take into account their random variations. On the other hand, recent deterministic studies on VU emission assessment at the post-connection stage of unbalanced installations present a complex VU factor based approach to determine constituent components of the post-connection …

Probabilistic analysis of traffic loading on a bridge traditionally involves an extrapolation from measured or simulated load effects to a characteristic maximum value. In recent years, Long Run Simulation, whereby thousands of years of traffic are simulated, has allowed researchers to gain new insights into the nature of the traffic scenarios that govern at the limit state. For example, mobile cranes and low-loaders, sometimes accompanied by a common articulated truck, have been shown to govern in most cases. In this paper, the extreme loading scenarios identified in the Long Run Simulation are applied to a non-linear, two-dimensional (2D) plate finite …

Resistance and loads are often correlated in time and space. The paper assesses the influence of these correlations on structural reliability/probability of failure for a typical two-lane RC slab bridge under realistic traffic loading. Spatial variables for structural resistance are cover and concrete compressive strength, which in turn affect the strength and chloride-induced corrosion of RC elements. Random variables include pit depth and model error. Correlation of weights between trucks in adjacent lanes and inter-vehicle gaps are also included and are calibrated against Weigh-In-Motion (WIM) data. Reliability analysis of deteriorating bridges needs to incorporate uncertainties associated with parameters governing the …
