Aerial Object Detection for Water-Based Search & Rescue Open
Responding to a water rescue situation is challenging. First responders need access to data as quickly as possible to increase the likelihood of a successful rescue. Using aerial imagery systems is especially useful in a search and rescue …
Roughness Power Spectral Density as a Function of Aerial Image and Basic Process / Resist Parameters Open
Linewidth Roughness (LWR) remains a difficult challenge for improvement in all resist materials. In previous work we focused on the impact of key components of LWR by analyzing the Power Spectral Density (PSD) curves which can be obtained …
Evaluation of Sorbent Sampling and Analysis Procedures for Acetone in Workplace Air: Variations of Concentration and Relative Humidity Open
This study experimentally evaluates the performance of different sorbent tubes for sampling acetone vapor in workplace air. A dynamic atmosphere system produced an acetone alone and a mixture with other analytes containing ~73, 483, and 18…
Fractal light from lasers Open
Fractals, complex shapes with structure at multiple scales, have long been\nobserved in Nature: as symmetric fractals in plants and sea shells, and as\nstatistical fractals in clouds, mountains and coastlines. With their highly\npolished s…
Utilizing Roughness Power Spectral Density Variables to Guide Resist Formulation and Understand Impact of Frequency Analysis through Process Open
Linewidth roughness (LWR) remains a difficult challenge for improvement in all resist materials. In this paper, we intend to focus on the impact of key components of LWR by analyzing the power spectral density (PSD) curves which can be obt…
Fractal laser modes data and evaluation tools Open
Software for theoretically modelling fractal laser modes; raw data of experimentally measured intensity cross-sections in fractal laser modes, and tools for evaluating these
