VALIDATION OF ON-LINE MONITORING TECHNIQUES TO NUCLEAR PLANT DATA

Garvey, Jamie,Garvey, Dustin,Seibert, Rebecca,Hines, J. Wesley Korean Nuclear Society 2007 Nuclear Engineering and Technology Vol.39 No.2

The Electric Power Research Institute (EPRI) demonstrated a method for monitoring the performance of instrument channels in Topical Report (TR) 104965, 'On-Line Monitoring of Instrument Channel Performance.' This paper presents the results of several models originally developed by EPRI to monitor three nuclear plant sensor sets: Pressurizer Level, Reactor Protection System (RPS) Loop A, and Reactor Coolant System (RCS) Loop A Steam Generator (SG) Level. The sensor sets investigated include one redundant sensor model and two non-redundant sensor models. Each model employs an Auto-Associative Kernel Regression (AAKR) model architecture to predict correct sensor behavior. Performance of each of the developed models is evaluated using four metrics: accuracy, auto-sensitivity, cross-sensitivity, and newly developed Error Uncertainty Limit Monitoring (EULM) detectability. The uncertainty estimate for each model is also calculated through two methods: analytic formulas and Monte Carlo estimation. The uncertainty estimates are verified by calculating confidence interval coverages to assure that 95% of the measured data fall within the confidence intervals. The model performance evaluation identified the Pressurizer Level model as acceptable for on-line monitoring (OLM) implementation. The other two models, RPS Loop A and RCS Loop A SG Level, highlight two common problems that occur in model development and evaluation, namely faulty data and poor signal selection

REACHING FOR HOLOGRAMS : ASSESSING THE ERGONOMICS OF THE MICROSOFT™ HOLOLENS™ 3D GESTURE KNOWN AS THE AIR TAP

Jed Looker,Thomas Garvey 한국디자인학회 2015 한국디자인학회 학술발표대회 논문집 Vol.2015 No.10

This paper assesses the ergonomics of the air tap, a 3D gesture used to interact with the Hololens™, a head-mounted optical see-through display being developed by Microsoft™. After reviewing ergonomics literature we found the air tap appeared to be outside of known anthroprometric and biomechanical limits and tolerances. Because the Hololens was unavailable for testing at the time of writing, the air tap was evaluated using methods that support general, observational data. The Rapid Entire Body Assessment (REBA), Rapid Upper Body Assessment (RULA) and Novel Ergonomic Postural Assessment (NERPA) methods were used to assess the gesture as observed in four videos. For all methods, higher scores suggested further investigation was required to avoid risk of developing musculoskeletal disorders. Although the neck trunk and leg portion of the REBA score was low, the arm and wrist portions gained more points. This was further reflected in overall high RULA and NERPA scores which focused more on the upper region of the body. Although these findings cannot be used to accurately assess whether the air tap suffers from poor ergonomics or puts the user at risk of developing musculoskeletal disorders, they do suggest the gesture might benefit from a more thorough investigation. This paper concludes by proposing future research into developing and validating an ergonomic framework designers and developers can use to develop 3D gestures.

Feasibility of RF Sensor Application for On-line Monitoring of Tomato Paste Processing

Kim, Seong-Min,Garvey, Casey,Leary, Thomas,McCarthy, Michael Korean Society for Agricultural Machinery 2008 바이오시스템공학 Vol.33 No.6

On-line monitoring of fresh tomato paste processing was done using two radio frequency (RF) sensors resonant at 85 and 110 MHz. Fresh tomato juice with soluble solid content of about $5^{\circ}Brix$ was evaporated up to $23^{\circ}Brix$ and diluted down to about $5^{\circ}Brix$ again with a pilot scale evaporator. The RF sensors were installed in a processing pipe and monitored. The pastes at a specific $^{\circ}Brix$ level were sampled and analyzed for physical properties such as soluble solid content and viscosity. The relationships between sensor outputs and measured physical properties were analyzed. Analysis results showed RF sensor is feasible to apply on-line monitoring of tomato paste processing.

IMPROVING MENTAL HEALTH IN STUDENT HOUSING

Ellen Hrinivich,Thomas Garvey 한국디자인학회 2015 한국디자인학회 학술발표대회 논문집 Vol.2015 No.10

This paper explores the very real connection between the design of physical space and the emotional impact on mental health. In particular there is great potential in the context of student housing. The two main principals in this paper are that a residence must support 3 layers of social interaction: society, friendship and solitude, the other is that the physical design must take advantage of recent research in embodied cognition -- the body’s position can change thought patterns and stress levels. The goals of the space are to help a person improve their confidence and mental wellbeing, to provide assistance to students at early stages of distress while maintaining a level of social comfort and to provide early intervention for mental health issues before they begin. An original feature is the artistic style in which these ideas are communicated. The design provides a positive spin to a topic associated with sadness and loneliness. Presenting the ideas in a superhero artistic style matches the optimistic themes. The designed space produces tangible outcomes to improve student mental health and increase awareness of mental health issues without the negative stigma and intimidation associated with current on-campus mental health assistance.

Concentrated Trading and Order Execution Costs

Fei Wu,Ryan Garvey,Tao Huang 한국증권학회 2014 Asia-Pacific Journal of Financial Studies Vol.43 No.6

Prior studies indicate that investors who hold more concentrated investment portfolios per-form better. In our paper, we examine whether concentration benefits occur in trading set-tings. We find that US traders who focus on fewer stocks pay lower order execution costs. Concentrated trading behavior is correlated across different dimensions. Traders who concen-trate on a smaller number of stocks also concentrate in fewer market centers, at particulartimes of the day, and on certain order types. Our results suggest that trading costs varyacross market participants, and that by focusing on a smaller subset of securities, traders gainadvantages for order execution.
