Development Of Food Packaging Films Based On Cellulose Nanocrystals (Cncs), Cong Chen
Development Of Food Packaging Films Based On Cellulose Nanocrystals (Cncs), Cong Chen
Electronic Theses and Dissertations
Food packaging provides means to mitigate food spoilage caused by microbes and environmental exposure, as well as prolonging the shelf life of food products in a cost-effective manner that industry and consumers desire while minimizing environmental impact. However, conventional plastics are unsustainable, nonrenewable, as well as nondegradable, and coupled with single-use culture can cause serious environmental pollution and the loss of resources. Taking the above issues into consideration, bio-based materials with the required properties are desirable to address the end-of-life issues for packaging.
Cellulose nanocrystals (CNCs), as a major type of cellulose nanomaterials are directly extracted from renewable biomass resources …
Towards A Filmic Look And Feel In Real Time Computer Graphics, Sherief Farouk
Towards A Filmic Look And Feel In Real Time Computer Graphics, Sherief Farouk
Electronic Theses and Dissertations
Film footage has a distinct look and feel that audience can instantly recognize, making its replication desirable for computer generated graphics. This thesis presents methods capable of replicating significant portions of the film look and feel while being able to fit within the constraints imposed by real-time computer generated graphics on consumer hardware.
Study Of Discharge Coefficient And Trends In Film Cooling Effectiveness Of Conical Holes With Increasing Diffusion Angles, Humberto Zuniga,
Study Of Discharge Coefficient And Trends In Film Cooling Effectiveness Of Conical Holes With Increasing Diffusion Angles, Humberto Zuniga,
Electronic Theses and Dissertations
Previous studies indicate that increasing the diffusion angle in conical film-cooling holes leads to an improvement in their film cooling effectiveness. Discharge coefficient and film cooling effectiveness measurements are conducted to characterize this behavior. Part of the focus of this investigation is to find out how this trend develops and attempt to ascertain the optimum cone angle, if possible. Six test plates, each with one row of eight conical-shaped cooling holes of equal diffusion angles of 0, 1, 2, 3, 6, or 8 [degrees], with respect to the hole axis are used in this study. The ratios of the hole …
