Microstructure Evolution and Mechanical Response of Material by Friction Stir Processing and Modeling

Description: In this study, we have investigated the relationship between the process-microstructure to predict and modify the material's properties. Understanding these relationships allows the identification and correction of processing deficiencies when the desired properties are not achieved, depending on the microstructure. Hence, the co-relation between process-microstructure-properties helped reduce the number of experiments, materials & tool costs and saved much time. In the case of high entropy all… more

Firm Performance and Analyst Forecast Accuracy Following Discontinued Operations: Evidence from the Pre-SFAS 144 and SFAS 144 Eras

Description: Because of the non-recurring and transitory nature of discontinued operations, accounting standards require that the results of discontinued operations be separately reported on the income statement. Prior accounting literature supports the view that discontinued operations are non-recurring or transitory in nature, and also suggests that income classified as transitory has minimal relevance in firm valuation.

Wealth and Regime Formation: Social and Economic Origins of the Change Toward Democracy

Description: This study explores the relationship between economic development, social mobility, elites, and regime formation.

Efficient Solar Energy Harvesting and Management for Wireless Sensor Networks under Varying Solar Irradiance Conditions

Description: Although wireless sensor networks have been successfully used for environmental monitoring, one of the major challenges that this technology has been facing is supplying continuous and reliable electrical power during long-term field deployment. Batteries require repetitive visits to the deployment site to replace them once discharged; admittedly, they can be recharged from solar panels, but this only works in open areas where solar radiation is unrestricted. This dissertation introduces a nove… more

Examining the "Portfolio Careers" of Classical Musician Entrepreneurs through the Lens of Seven Clarinetists

Music careers have traditionally included teaching positions in academia and performance positions in professional ensembles. Because of the limited number of jobs in these two areas, clarinetists, and classical musicians in general, often turn to work that provides financial security but may lack artistic… more

Developing Precipitation Hardenable High Entropy Alloys

Description: High entropy alloys (HEAs) is a concept wherein alloys are constructed with five or more elements mixed in equal proportions; these are also known as multi-principle elements (MPEs) or complex concentrated alloys (CCAs). This PhD thesis dissertation presents research conducted to develop precipitation-hardenable high entropy alloys using a much-studied fcc-based equi-atomic quaternary alloy (CoCrFeNi). Minor additions of aluminium make the alloy amenable for precipitating ordered intermetallic … more

A study of continuing bonds and their impact on life attitudes in parents of murdered children.

Description: For most of the past century, the positive outcome of grief in the West was characterized as the relinquishment of the bond to the deceased. Phrases such as "let go", "move on", and "get over it" were, and continue to be, common to the language of this pursuit. This 'breaking bonds' perspective does not take into account other means of grief resolution, nor does it consider historical or cultural findings. Consequently, reports of bereaved parents who indicate resolution of grief yet maintain a… more
