Flexible Buffer Materials To Reduce Contact Resistance In Thermal Insulation Measurements, R. E. Clarke, G. Rosengarten, B. Shabani

International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES)

Thermal insulation test methods approach their lower limits as thermal resistance falls below 0.1 m²⋅K/W. This is the minimum value specified in ASTM C 518 (ASTM International, 2010b) while ASTM C 177 (ASTM International, 2010a) proposes about 0.06 m²⋅K/W. Nevertheless these are the test methods, along with their ISO equivalents, required by Australasian building codes and directed at many products and materials with thermal resistance on the low side of 0.1 m²⋅K/W. Alternatives, such as ASTM E 1530 (ASTM International, 2011), cover much lower resistances but require carefully prepared small specimens and very-high contact …

Bilateral National Metrology Institute Comparison Of Guarded-Hot-Plate Apparatus, Alain Koenen, Robert R. Zarr, William F. Guthrie

International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES)

Two national metrology institutes have conducted an international interlaboratory comparison on thermal conductivity for two thermal insulation reference materials. The Laboratoire national de métrologie et d’essais (LNE), France, and the National Institute of Standards and Technology (NIST), United States, present measurements obtained by the guarded-hot-plate method. The study involved two materials: expanded polystyrene board (EPS) and fibrous glass board (FGB). The EPS was provided by the LNE and is issued as a transfer specimen; the FGB provided by NIST was issued as Standard Reference Material (SRM) 1450c. For each reference material, the study was based on four independent measurements at …

Microstructure And Thermal Conductivity Modeling Of Granular Nanoplatelet Assemblies, Ishan Srivastava, Timothy S. Fisher

International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES)

Consolidation and sintering of bismuth telluride nanoplatelets is a cost-effective method of manufacturing high thermoelectric figure-of-merit materials. A structural optimization method is employed here to study the effects of columnar structures formed by nanoplatelet composites on thermal transport. The initially sparse and random distribution of nanoplatelets is compacted into a jammed state under an external hydrostatic stress, thereby simulating the compaction of nanopowders in experiments. The jammed morphology exhibits randomly oriented stacks of nanoplatelets and a discontinuous distribution of the pore phase within the microstructure. Grain and pore morphologies are statistically quantified using computational geometry techniques. High aspect ratio nanoplatelets …

Metal Hydride Component Design (Mhy-Code) Tool For The Selection Of Hydrides In Thermal Systems, Essene L. Waters, Timothée L. Pourpoint, Tyler G. Voskuilen

International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES)

A system has been developed to enable the targeted down-selection of an extensive database of metal hydrides to identify the most promising materials for use in thermal systems. The materials’ database contains over 300 metal hydrides with various physical and thermodynamic properties included for each material. Submodels for equilibrium pressure, thermophysical data, and default properties are used to predict the behavior of each material within the given system. The application used at this time is a stationary combined heat and power system containing a hightemperature proton exchange membrane (PEM) fuel cell, a hot water tank, and two metal hydride beds …

Characterization Work And Comparative Testing Of Expanded Glass Granulate As A Round Robin Material For Thermal Conductivity At Higher Temperatures, Roland Schreiner, Ernst-G. Hencke

International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES)

For laboratories within the scheme of the voluntary surveillance system for technical insulation materials in Europe (VDI/Keymark), a proficiency test is the basis for obtaining a “registered laboratory.” The VDI/Keymark is a cooperation between the VDI, The Association of German Engineers, and the Keymark Group dealing with European voluntary product certification systems, within the scope of thermal insulation materials. Registered laboratories are allowed to conduct measurements to verify the declared thermal conductivity curve of technical insulation materials under the umbrella of the quality mark “VDI/Keymark”. The initial characterization work on a round robin material for the determination of thermal conductivity …

Thermal Conductivity Of Simulated Soils By The Needle Probe Method For Energy Foundation Applications, J. E. Low, F. A. Loveridge, W. Powrie

International Thermal Conductivity Conference (ITCC) and the International Thermal Expansion Symposium (ITES)

Soil thermal conductivity is an important parameter in the design of ground source heat pump and energy foundation systems. A laboratory method for measuring the soil thermal conductivity is the needle probe method. Earlier, analysis of the needle probe test data has been simplistic, relying heavily on human judgment and rules of thumb. This article presents an alternative method of analyzing the needle probe data with the aid of MATLAB, which is a technical programming language and computing environment. Four agar–kaolin specimens of varying densities were prepared to resemble simple soils. These were tested using the needle probe for a …

Using A Work System Metamodel And Usdl To Build A Bridge Between Business Service Systems And Service Computing, Steven Alter, Alistair Barros

Business Analytics and Information Systems

This paper explores the support for more comprehensive modeling of service systems than that possible through modeling methods developed through partial perspectives, with uncertainties about their wider suitability and need for integration with other methods in this domain. It responds to a Dual Call for Papers from INFORMS Service Science and IEEE Transactions on Service Computing requesting contributions that address the barely explored challenge of establishing links between business views of service systems and more technical views from service computing. Competing definitions of service reveal that most business views of service emphasize acts or outcomes produced for others, whereas a …

Big Data Proteogenomics And High Performance Computing: Challenges And Opportunities, Fahad Saeed

Parallel Computing and Data Science Lab Technical Reports

Proteogenomics is an emerging field of systems biology research at the intersection of proteomics and genomics. Two high-throughput technologies, Mass Spectrometry (MS) for proteomics and Next Generation Sequencing (NGS) machines for genomics are required to conduct proteogenomics studies. Independently both MS and NGS technologies are inflicted with data deluge which creates problems of storage, transfer, analysis and visualization. Integrating these big data sets (NGS+MS) for proteogenomics studies compounds all of the associated computational problems. Existing sequential algorithms for these proteogenomics datasets analysis are inadequate for big data and high performance computing (HPC) solutions are almost non-existent. The purpose of this …

Application Of Goldratt’S Thinking Process To Constraints Within An Emergency Department—A Case Study, Augustine O. Amonge

Masters Theses & Specialist Projects

Emergency department (ED) acts as a feeder to many hospitals as it determines a large proportion of admissions. ED also acts as a buffer zone for many patients who cannot get care in other institutions due to insurance issues. Most hospitals are trying to invest heavily on their EDs, but cannot meet patients’ satisfaction in terms of cost and quality of care. There is great need for EDs to understand customers’ expectation given the rising cost of healthcare.

The focus of this study is at an ED center in Bowling Green Kentucky, using theory of constraints (TOC) thinking process application …
