Numerical investigation of the pollutant dispersion in the heterogeneous urban settings from rooftop sources
DownloadSpring 2024
Exhaust gases emitted from roof-based sources are recognized as one of the primary sources of urban air pollution that could considerably deteriorate both outdoor and indoor air quality. Urban planners frequently use analytical and semi-empirical dispersion models to assess the pollutant...

Design, Manufacturing and Development of Hybrid Manufacturing System for Rapid Investment Casting
DownloadSpring 2024
Direct rapid investment casting integrates additive manufacturing (AM) technology into conventional investment casting. This approach addresses the challenges of high lead time and cost but is effective only on a small scale (up to a cube of 0.3 m side). It utilizes thermoplastics such as...

A Study on the Strain-Rate- and Stress-State-Dependent Behavior of Advanced Ceramics: Experimental Mechanics and Multiscale Simulations
DownloadFall 2024
Design and development of better-performing ceramic structures are vital in industry-driven applications where a wide range of strain rates and stress states are induced in the material (e.g., impact events). Accordingly, this thesis investigates the strain-rate and stress-state-dependent...
