Measuring Instrument Precision Estimation in Destructive Testing

Creator:: Sunil Raj, Sayooj
Abstract:: The variability introduced into measurements by a measuring instrument is referred to as measurement instrument precision. Experimental procedures and analysis methods exist when measurements are repeatable and can be repeated on the same item. However, when the measurements are destructive and repeated measurements are not possible, estimating measuring instrument precision...

Analysis and Comparison of Fixed-Size Lot and Fixed-Time Lot Batch Production Systems

Creator:: Tiwari, Prashant
Abstract:: In high volume automated discrete item batch production systems, the batches or lots are typically fixed quantity (i.e., size), with setups incurred between the different production lots. Processing times for the fixed-size lots are relatively constant when the workstation is operating however, random workstation disruptions cause variability in the lot...

Thermal Actuation and Atomization for Desalination Systems

Creator:: Sharma, Deepak
Abstract:: Desalination stands for removing salt from saline water, and produce freshwater. Desalination technologies have been envisioned as a potential solution for freshwater production from oceans as an immense source of water acquiring 97% earth’s water, and 75% of earth’s surface. However, one third of world’s population face water scarcity every...

Bi-criteria Scheduling in an Assembly Flow Shop with Limited Buffer Storage and Shift Production

Creator:: Aryal, Ayush R.
Abstract:: In this research, the comparative performance of permutation and non-permutation schedules is investigated in an assembly flow shop (AFS) with shift production, where a limited buffer storage is available between two machines. Most of the traditional scheduling problems consider continuous production, i.e., production occurs for 24 hours (3 * 8-hour...

Development and evaluation of novel coupling agents for kenaf-fiber-reinforced unsaturated polyester composites

Creator:: Ren, Xiaofeng
Abstract:: Natural fibers are gaining popularity as reinforcement materials for thermoset resins over the last two decades. Natural fibers are inexpensive, abundant, renewable and environmentally friendly. Kenaf fibers are one of the natural fibers that can potentially be used for reinforcing unsaturated polyester (UPE). As a polymer matrix, UPE enjoys a...

An Investigation on Nanoscale-shape-mediated Coupling Between Temperature and Densification in Intense Pulsed Light Sintering of Silver Nanoparticles

Creator:: Bansal, Shalu
Abstract:: In Intense Pulsed Light (IPL) sintering, pulsed large-area visible light from a xenon lamp is absorbed by nanoparticle films or patterns and converted to heat, resulting in rapid sintering of the nanoparticles. This work experimentally characterizes IPL sintering of silver nanoparticle films. A newly observed turning point in the evolution...

Characterization and Development of Ni-based Superalloys for Supercritical Carbon Dioxide Applications

Creator:: Adam, Benjamin M.
Abstract:: The advent of supercritical CO2 as a new heat-exchange medium has seen strong interest from the power industry and the energy research field recently. It is advan- tageous in comparison with other heat-exchange cycles, as it can be operated safely at much higher temperatures and pressures, thus increasing the thermal...

Defining and comparing risks and success measures of the reference design process and traditional new product development processes

Creator:: Larson, Tasha M.
Abstract:: To address aggressive global competition, retain customers and increase revenue, firms are required to pursue New Product Development (NPD) projects. Ventures of this nature are risky and fail often. Numerous factors influence the survival of a project. In this research, 16 factors have been identified and selected as indicators of...

Local heat transfer rate and bubble dynamics during jet impingement boiling

Creator:: Mani, Preeti
Abstract:: Characterization of local boiling trends, in addition to the typically reported area-averaged trends, is essential for the robust design and implementation of phase change technologies to sensitive heat transfer applications such as electronics cooling. Obtaining the values of heat fluxes corresponding to locally varying surface temperatures has been a challenge...

The effects of nanoparticle addition on the processing, structure and properties of SiC and AlN

Creator:: Onbattuvelli, Valmikanathan P.
Abstract:: Silicon carbide (SiC) and aluminum nitride (AlN) exhibit a combination of thermal and mechanical properties that are relevant to applications in electronics, aerospace, defense and automotive industries. However, the successful translation of these properties into final applications lies in the net-shaping of these ceramics into fully dense microstructures. Increasing the...
