The first three experiments compared different prototype gesture control designs as participants used the systems in a driving simulator. The fourth experiment sought to answer more basic questions about how auditory displays influence performance in target acquisition tasks. Results from experiment 1 offered optimism for the potential of auditory-supported displays for navigating simple menus ...


Creating Garment Simulations: Effectiveness Of Traditional Textile Testing Equipment Versus Kes And Fast Systems, Evrim Buyukaslan, Fatma Baytar, Fatma Kalaoglu 2018 Istanbul Technical University

Creating Garment Simulations: Effectiveness Of Traditional Textile Testing Equipment Versus Kes And Fast Systems, Evrim Buyukaslan, Fatma Baytar, Fatma Kalaoglu

International Textile and Apparel Association (ITAA) Annual Conference Proceedings

3D virtual garment simulation software packages offer various fabric alternatives in their fabric libraries. However, these libraries are limited in terms of providing their users with particular fabric compositions, structures, and drape properties. When a specific fabric needs to be used for a garment simulation to understand how the end-product would look like, individual fabric mechanical properties must be entered into the software. For this purpose, usually fabric mechanical values measured by either KES or FAST systems are used. Although these systems provide precise measurements, they are very expensive to obtain. Our research questions emerged from the need to use ...

Rapid And Damage-Free Outgassing Of Implanted Helium From Amorphous Silicon Oxycarbide, Qing Su, Hepeng Ding, Lloyd Price, Lin Shao, Jonathan A. Hinks, Graeme Greaves, Stephen E. Donnelly, Michael J. Demkowicz, Michael Nastasi

NCESR Publications and Research

Damage caused by implanted helium (He) is a major concern for material performance in future nuclear reactors. We use a combination of experiments and modeling to demonstrate that amorphous silicon oxycarbide (SiOC) is immune to He-induced damage. By contrast with other solids, where implanted He becomes immobilized in nanometer-scale precipitates, He in SiOC remains in solution and outgasses from the material via atomic-scale diffusion without damaging its free surfaces. Furthermore, the behavior of He in SiOC is not sensitive to the exact concentration of carbon and hydrogen in this material, indicating that the composition of SiOC may be tuned to ...

Simultaneous Electrical And Mechanical Resonance Drive For Large Signal Amplification Of Micro Resonators, M. H. Hasan, Fadi M. Alsaleem, N. Jaber, M. A. A. Hafiz, M. I. Younis

Architectural Engineering -- Faculty Publications

Achieving large signal-noise ratio using low levels of excitation signal is key requirement for practical applications of micro and nano electromechanical resonators. In this work, we introduce the double electromechanical resonance drive concept to achieve an order-of-magnitude dynamic signal amplification in micro resonators. The concept relies on simultaneously activating the micro-resonator mechanical and electrical resonance frequencies. We report an input voltage amplification up to 15 times for a micro-resonator when its electrical resonance is tuned to match the mechanical resonance that leads to dynamic signal amplification in air (Quality factor enhancement). Furthermore, using a multi-frequency excitation technique, input voltage and ...

Method For Radon Measurement In Residential Sewer Connections, David Yuill 2018 University of Nebraska-Lincoln

Method For Radon Measurement In Residential Sewer Connections, David Yuill

Architectural Engineering -- Faculty Publications

Radon gas is the most deadly indoor air pollutant. In the US, it is responsible for over 20,000 deaths per year. Residential exposure is typically the largest portion of a person’s annual exposure, so a great deal of research has been done to understand the pathways that radon can follow to enter a house. Since radon emanates from the ground, it is present in high concentration in soil gas. Recent research on the vapor intrusion of volatile organic compounds from subsurface sources into a test house concluded that the sewer line is an important preferential pathway. Despite the ...

Impact Of Owners’ Early Decisions On Project Performance And Dispute Occurrence In Public Highway Projects, Sogand Hasanzadeh, Behzad Esmaeili, Ghada M. Gad, Douglas D. Gransberg

Architectural Engineering -- Faculty Publications

Disputes are common in the construction industry and lead to unnecessary cost and schedule overruns in projects. It is commonly believed that owners’ early decisions regarding the selection of delivery methods, procurement methods, and contract types impact the frequency and severity of project disputes; however, no previous study has empirically tested this hypothesis, particularly in highway public projects. Therefore, this study empirically investigated the impact of owners’ early decisions regarding project organization (i.e., delivery methods, procurement, and contract types) on performance measures (e.g., cost and schedule growth), specifically dispute performance metrics (e.g., frequency and severity of disputes ...


Comfort-Based Optimal Temperature Setpoint Calculation, Andrew Holthaus, Mostafa Rafaie, Fadi Alsaleem 2018 University of Nebraska - Lincoln

Comfort-Based Optimal Temperature Setpoint Calculation, Andrew Holthaus, Mostafa Rafaie, Fadi Alsaleem

Architectural Engineering -- Faculty Publications

General practice in current building HVAC control is to select building temperature setpoints that comply with ASHRAE Standard 55. By meeting this standard, based on the PMV comfort model, 80% of building occupants should be satisfied with their thermal environment. However, unfortunately, this is rarely the case. One possible reason for this is the variation in occupant activity and clothing that are usually assumed default values using this standard. In this work, we present an iterative-based algorithm to solve this problem. The algorithm solves the PMV inverse model equation to determine the optimal temperature setpoint while inferring human activity level ...


Numerical Simulation Of Fault Impacts For Commercial Walk-In Freezers, Alireza Behfar, David P. Yuill 2018 University of Nebraska - Lincoln

Numerical Simulation Of Fault Impacts For Commercial Walk-In Freezers, Alireza Behfar, David P. Yuill

Architectural Engineering -- Faculty Publications

Refrigeration systems can undergo many faults that could negatively affect their operation and performance. This paper describes a modeling process to simulate the fault impacts on the operation of a commercial walk-in freezer using semi-empirical models. These models often require less modeling effort than full forward models and could be used in scenarios where detailed information is missing, such as in field-measured systems. An important characteristic of a typical walk-in refrigeration system is the existence of a liquid-line receiver after the condenser, which significantly changes the behavior of the cycle, in comparison to a receiver-less system. Component models described in ...

Zipping Through Time: Extending The Life Of Children's Wear With Transformable Design, Michelle Park, Ja Young Hwang Ph.D., Haviet Huong, Shalia Johnson, Yahan Quing

International Textile and Apparel Association (ITAA) Annual Conference Proceedings

This project is focused on addressing the problem of children outgrowing their garments too quickly. Designs focus on transforming garments to be used for multiple purposes, in particular a transformable waterproof baby carrier cover/ children's poncho and a size-changing dress. The designed garments were based on client needs, and longevity was approached by transforming both size and function. Size was addressed by using zippers, panels, and buttons; function was approached by selection of two items in the same category of use, i.e., as the child changes, so does the garment. The implementation of strategic expansion points effectively extends ...

Influence Of Atmospheric Clearness On Pdlc Switchable Glazing Transmission, Aritra Ghosh, Brian Norton, Tapas K. Mallick 2018 Technological University Dublin

Influence Of Atmospheric Clearness On Pdlc Switchable Glazing Transmission, Aritra Ghosh, Brian Norton, Tapas K. Mallick

Articles

Electrically activated switchable polymer dispersed liquid crystal (PDLC) is suitable for adaptive windows. A particular type requires 20V to become 71% transparent while in the absence of power it is 27% transparent. Glazing transmission changes with light incident angle. As the clearness of a sky changes the fraction changes alter of direct insolation (that has an azimuthally changing incident) and diffuse insolation (that has a largely constant incident). Thus, the effective overall incident angle determining the glazing transmittance also changes. In this work for the first time, the variation of PDLC glazing transmission with clearness index has been investigated.
