Pragmatic Development During Study Abroad: L2 Intensifiers In Spoken Spanish, Lori Czerwionka, Daniel J. Olson

School of Languages and Cultures Faculty Publications

The current investigation examined the development of second language (L2) intensifier use in spoken Spanish over a 6-week immersion program in Madrid (n = 45). Native Spanish speakers from Madrid (n = 10) served as a comparison group to represent the local ambient input or sociopragmatic norm to which L2 learners were exposed. Data were extracted from semi-structured interviews. Results exposed different developmental trends over the program for intensifier frequency, intensifier lexical diversity, and intensifier collocations. While learners already had a strong sense of which intensifiers were most frequent in Spanish and how to use them in appropriate linguistic environments …

Time-Resolved Characterization Of Microchannel Flow Boiling During Transient Heating: Part 1 – Dynamic Response To A Single Heat Flux Pulse, T. A. Kingston, J. A. Weibel, S V. Garimella

CTRC Research Publications

Microchannel flow boiling is an attractive approach for the thermal management of high-heat-flux elec- tronic devices that are often operated in transient modes. In Part 1 of this two-part study, the dynamic response of a heated 500 μm channel undergoing flow boiling of HFE-7100 is experimentally investigated for a single heat flux pulse. Three heat flux levels exhibiting highly contrasting flow behavior under con- stant heating conditions are used: a low heat flux corresponding to single-phase flow (15 kW/m 2 ), an intermediate heat flux corresponding to continuous flow boiling (75 kW/m 2 ), and a very high heat flux …

Thermal Conductivity Of Ultra High Molecular Weight Polyethylene: From Fibers To Fabrics, A. A. Candadai, J. A. Weibel, A. M. Marconnet

CTRC Research Publications

Unique combinations of properties such as mechanical compliance and chemical stability make polymers attractive for many applications. However, the intrinsic low thermal conductivity of bulk polymers has generally limited their potential for heat dissipation applications, and in fact they are widely used as thermal insulators. But in recent years, gel-spun, ultraoriented fibers made of ultrahigh molecular weight polyethylene (UHMW-PE) have sparked interest in the thermal management community due to their exceptionally high thermal conductivity. These fibers are typically used in commercially produced protective gear such as motorcycle jackets and ballistic vests due to their high mechanical strength, but they have …

Demonstration Of A Compliant Micro-Spring Array As A Thermal Interface Material For Pluggable Optoelectronic Transceiver Modules, J. Cui, L. Pan, J. A. Weibel

CTRC Research Publications

Pluggable optoelectronic transceiver modules are widely used in the fiber-optic communication infrastructure. It is essential to mitigate thermal contact resistance between the highpower optical module and its riding heat sink in order to maintain the required operation temperature. The pluggable nature of the modules requires dry contact thermal interfaces that permit repeated insertion–disconnect cycles under low compression pressures (~10 to 100 kPa). Conventional wet thermal interface materials (TIM), such as greases, or those that require high compression pressures, are not suitable for pluggable operation. Here, we demonstrate the use of compliant microstructured TIM to enhance the thermal contact conductance between …

Characterizing Interstate Crash Rates Based On Traffic Congestion Using Probe Vehicle Data, Michelle M. Mekker, Stephen M. Remias, Margaret L. Mcnamara, Darcy M. Bullock

JTRP Affiliated Reports

Crash reduction factors are widely used by engineers for prioritizing safety investments. Work zones are routinely analyzed by the length and duration of queues. Queue detection warning technology has been growing in availability and reliability in recent years. However, there is sparse literature on the impact of freeway queueing on crash rates. This paper analyzes three years of crash data and crowd-sourced probe vehicle data to classify crashes as being associated with queueing conditions or free flow conditions. In 2014, only 1.2% of the distanced-weighted hours of operation of Indiana interstates operated at or under 45 MPH. A three-year study …

Time Series Analysis Of Water Use And Indirect Reusewithin A Huc-4 Basin (Wabash) Over A Nine Year Period, M. Julia Wiener, Sebastian Moreno, Chad T. Jafvert, Loring F. Nies

Lyles School of Civil Engineering Faculty Publications

Anthropogenic water use and reuse represent major components of the water cycle. In the context of climate change, water reuse and recycling are considered necessary components for an integrated water management approach. Unplanned, or de facto, indirect water reuse occurs in most of the U.S. river systems, however, there is little real-time documentation of it. Despite the fact that there are national and state agencies that systematically collect data on water withdrawals and wastewater discharges, their databases are organized and managed in a way that makes it challenging to use them for water resource management analysis. The ability to combine …

JTRP Technical Reports

The 2007 Great Recession is widely considered the worst economic downturn in recent United States History. In Indiana, the unemployment rate reached 10.6%, and took nearly seven years to return to pre-recession levels. However, employment data from this period shows that the change in total employment at the county level ranged from -20% to +5%, indicating that while many counties suffered from high unemployment, other counties experienced gains in total employment. Various research efforts, including this project, have been undertaken to understand the local characteristics that influence the differing degrees to which regional/city economies were able to resist or cope …

Determining The Optimal Traffic Opening Timing Through An In-Situ Ndt Method For Concrete Early Age Properties, Yen-Fang Su, Guangshuai Han, Na (Luna) Lu

JTRP Technical Reports

Developing a reliable in-situ testing method to determine the strength of concrete for traffic opening is a critical need for INDOT, due to the fast-pace construction schedule exposes concrete pavements and/or structures undergoing a substantial loading conditions even at its early ages. Nevertheless, the current methods for determining traffic opening times are inefficient and expensive, often causing construction delays or cost overruns. To address this critical need, we propose to develop an in-situ nondestructive testing (NDT) method that enables an accurate and efficient understanding of early age properties of concrete using electromechanical impedance (EMI) method coupled with piezoelectric sensors.

Concrete Box Beam Risk Assessment And Mitigation: Volume 1—Evolution And Performance, Robert J. Frosch, Christopher S. Williams, Ryan T. Molley, Ryan T. Whelchel

JTRP Technical Reports

Adjacent box beam bridges have a history of poor long-term performance including premature deterioration and failures. Leaking joints between box beams allow chloride-laden water to migrate through the superstructure and initiate corrosion. The nature of this deterioration leads to uncertainty of the extent and effect of deterioration on structural behavior. Due to limitations in previous research and understanding of the strength of deteriorated box beam bridges, conservative assumptions are made for the assessment and load rating of these bridges. Furthermore, the design of new box beam bridges, which can offer an efficient and economical solution, is often discouraged due to …

Investigation Of Design Alternatives For The Subbase Of Concrete Pavements, Amy Getchell, Luis Garzon Sabogal, Philippe L. Bourdeau, Marika Santagata

JTRP Technical Reports

In all pavement structures, one or more support layers separate the pavement from the subgrade. In addition to offering structural support, these layers have several important functions, which include: providing a stable and uniform construction platform, facilitating drainage, mitigating pumping of the subgrade fines, and protecting the pavement from the effects of frost heave. Their performance is critical in achieving the desired pavement smoothness, and in extending the service life of the structure. A range of designs, making use of unbound or stabilized aggregates and in some cases geosynthetics, are employed by different agencies to fulfill these functions.

Installation And Maintenance Of Raised Pavement Markers At State Transportation Agencies: Synthesis Of Current Practices, Hamed Zamenian, Dulcy M. Abraham

JTRP Technical Reports

Although raised pavement markers (RPMs) have been widely applied by the Indiana Department of Transportation (INDOT), there have been multiple cases where snowplowing activities have damaged pavements as well as the raised pavement markers on INDOT’s roadway assets. Dislodged raised pavement markers could reduce the design life of pavements because they leave openings for water and debris to infiltrate through pavement section. Interviews with INDOT personnel indicated that the proper installation of the markers and careful attention to the tooling of the center line of the concrete pavements could alleviate this problem. To explore issues related to the proper installation …

Extraction Of Vehicle Can Bus Data For Roadway Condition Monitoring, Howell Li, Enrique Saldivar-Carranza, Jijo K. Mathew, Woosung Kim, Jairaj Desai, Timothy Wells, Darcy M. Bullock

JTRP Technical Reports

Obtaining timely information across the state roadway network is important for monitoring the condition of the roads and operating characteristics of traffic. One of the most significant challenges in winter roadway maintenance is identifying emerging or deteriorating conditions before significant crashes occur. For instance, almost all modern vehicles have accelerometers, anti-lock brake (ABS) and traction control systems. This data can be read from the Controller Area Network (CAN) of the vehicle, and combined with GPS coordinates and cellular connectivity, can provide valuable on-the-ground sampling of vehicle dynamics at the onset of a storm. We are rapidly entering an era where …
