Reduction of Line Edge Roughness in Semiconductor Photoresist by Means of a Grazing Incidence Ion Beam
… decrease LER from the photoresist, post-develop smoothing techniques may be required to continue shrinking chip features economically. This work reports on one such method employing the use of an ion beam at grazing incidence along the features. This method smooths relatively long spatial length …

Field Evaluation Methodology for Quantifying Network-wide Efficiency, Energy, Emission, and Safety Impacts of Operational-level Transportation Projects
… also, investigates the ability of various data smoothing techniques to remove such erroneous data without significantly altering the underlying vehicle speed profile. Several smoothing techniques are then applied to the acceleration profile, including data trimming, Simple Exponential smoothing, …

Generation of high quality 2D meshes for given bathymetry
… and relevant dynamical scales. Two different smoothing techniques, Laplacian conditioning and targeted averaging, were applied to the fields involved in calculating the sizing matrix. The L² norm was used to quantify which technique had the greatest preservation of the original field. In both …

Phenomena that determine knock onset in spark-ignited engines
… listening to the engine. Bandpass filters and smoothing techniques were used to process the data. The processed data was then used to determine knock intensities for each cycle for both the cylinder pressure data and microphone signal. Also, the rate of build-up before reaching peak amplitude …

Optically Clear FDM Printing
… printer. I discovered that the other traditional smoothing techniques were not sufficient to create a clear surface, but resin coating could result in a fully transparent object. However, further research is needed to determine whether a specific focus can be repeatably created using this method, …

First- and Second-Order Properties of Spatiotemporal Point Patterns in the Space-Time and Frequency Domains
… intensities are examined using 3-dimensional smoothing techniques. Conditions for weak stationarity are provided so that subsequent second-order analysis can be conducted. We consider second-order analysis of spatiotemporal point patterns first in the space-time domain through an extension of …
