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

Morris Chang

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 ...

The Application Of Artificial Neural Networks For Prioritization Of Independent Variables Of A Discrete Event Simulation Model In A Manufacturing Environment, Rebecca Pires Dos Santos

Theses and Dissertations

The high complexity existent in businesses has required managers to rely on accurate and up to date information. Over the years, many tools have been created to give support to decision makers, such as discrete event simulation and artificial neural networks. Both tools have been applied to improve business performance; however, most of the time they are used separately. This research aims to interpret artificial neural network models that are applied to the data generated by a simulation model and determine which inputs have the most impact on the output of a business. This would allow prioritization of the variables ...

Spatial Sampling Strategies With Multiple Scientific Frames Of Reference, Paul B. Reverdy, Thomas F. Shipley, Daniel E. Koditschek 2017 University of Pennsylvania

Spatial Sampling Strategies With Multiple Scientific Frames Of Reference, Paul B. Reverdy, Thomas F. Shipley, Daniel E. Koditschek

Departmental Papers (ESE)

We study the spatial sampling strategies employed by field scientists studying aeolian processes, which are geophysical interactions between wind and terrain. As in geophysical field science in general, observations of aeolian processes are made and data gathered by carrying instruments to various locations and then deciding when and where to record a measurement. We focus on this decision-making process. Because sampling is physically laborious and time consuming, scientists often develop sampling plans in advance of deployment, i.e., employ an offline decision-making process. However, because of the unpredictable nature of field conditions, sampling strategies generally have to be updated online ...


Quasi-Static And Dynamic Mismatch For Door Opening And Stair Climbing With A Legged Robot, T. Turner Topping, Gavin Kenneally, Daniel E. Koditschek 2017 University of Pennsylvania

Quasi-Static And Dynamic Mismatch For Door Opening And Stair Climbing With A Legged Robot, T. Turner Topping, Gavin Kenneally, Daniel E. Koditschek

Departmental Papers (ESE)

This paper contributes to quantifying the notion of robotic fitness by developing a set of necessary conditions that determine whether a small quadruped has the ability to open a class of doors or climb a class of stairs using only quasi-static maneuvers. After verifying that several such machines from the recent robotics literature are mismatched in this sense to the common human scale environment, we present empirical workarounds for the Minitaur quadrupedal platform that enable it to leap up, force the door handle and push through the door, as well as bound up the stairs, thereby accomplishing through dynamical maneuvers ...

Facilitated-voluntary geographic information (f-VGI) is a promising method to enable systematic collection of data from residents about their physical and social environment. The method capitalizes on ubiquitous mobile smartphones to empower collection of geospatially-referenced data. It is important to evaluate the validity of user-generated content for use in research or program planning. The purpose of this study was to test whether the aggregated environmental (“bikeability”) ratings from novice community residents converges with ratings from experts using a robust research-based, paper audit-tool (the established Pedestrian Environment Data Scan (PEDS) tool). Equivalence testing statistically showed overall agreement between the composite ratings of ...

Reliability Of Wind Power Scenarios And Stochastic Unit Commitment Cost, Didem Sari, Sarah M. Ryan 2017 Iowa State University

Reliability Of Wind Power Scenarios And Stochastic Unit Commitment Cost, Didem Sari, Sarah M. Ryan

Sarah M. Ryan

Probabilistic wind power scenarios constitute a crucial input for stochastic day-ahead unit commitment in power systems with deep penetration of wind generation. To minimize the expected cost, the scenario time series of wind power amounts available should accurately represent the stochastic process for available wind power as it is estimated on the day ahead. The high computational demands of stochastic programming motivate a search for ways to evaluate scenarios without extensively simulating the stochastic unit commitment procedure. Reliability of wind power scenario sets can be assessed by statistical verification approaches. In this study, we examine the relationship between the statistical ...

This research attempts to improve the spatial interaction in virtual assembly with a focus on bimanual object manipulation. Using a unique combination of spatial interaction devices namely a kinesthetic haptic device (Phantom Omni®) and a magnetically tracked device (Razor Hydra) each held in one of the user hands; a new interaction technique named ‘Bimanual Stretched-String Single Object Manipulation’ (BS-SSOM) was developed [1]. The BS-SSOM technique decouples positioning and orientation of objects during bimanual single object manipulation in virtual assembly. The distance between the two hands can be varied to control the precision of manipulation. The simulation uses Voxmap Pointshell [2 ...


Dexterity: An Indicator Of Future Performance In Beginning Welders?, A. Preston Byrd, Richard Stone, Ryan G. Anderson 2017 Clemson University

Dexterity: An Indicator Of Future Performance In Beginning Welders?, A. Preston Byrd, Richard Stone, Ryan G. Anderson

Richard T. Stone

This study examined the use of dexterity to indicate future performance of beginning welders to select participants for welding training programs. With a high demand for welders, it is imperative that welding training programs be efficient, which can be time consuming (Stone, Watts, & Zhong, 2011). The time required to train certified welders is one of the obstacles training programs face. Many occupational fields have tried to predict a student’s future performance before admitting them into a training program by analyzing their dexterous ability. This study utilized the Complete Minnesota Dexterity Test (CMDT) to examine participants’ dexterity during a welding ...
