Observations on the observer pattern [PDF]

Proceedings of the 17th Conference on Pattern Languages of Programs, 2010
A group of students who should have been familiar with basic design principles and MVC all failed to implement the Observer design pattern correctly while at the same time violating several design principles. This paper discusses what went wrong and why it probably went wrong.

Improvements in aerosol layer height retrievals from TROPOMI oxygen A-band measurements by surface albedo fitting in optimal estimation [PDF]

Atmospheric Measurement Techniques
The aerosol layer height (ALH), from the Sentinel-5P/TROPOMI L2_AER_LH product, is based on an optimal estimation (OE) approach, fitting cloud-free measurements to synthetic reflectances in the strongest oxygen absorption band, provided by a neural ...

Low Ionosphere under Influence of Strong Solar Radiation: Diagnostics and Modeling

Applied Sciences, 2021
Solar flares (SFs) and intense radiation can generate additional ionization in the Earth’s atmosphere and affect its structure. These types of solar radiation and activity create sudden ionospheric disturbances (SIDs), affect electronic equipment on the ...

Overlap Correction Function For an Airborne Based Lidar

EPJ Web of Conferences, 2016
The present research envisages the estimation of the overlap correction function for an airborne nadir-mounted lidar using multi-angle measurements. We have scanned a series of offnadir angles and after data processing we have been able to determine the ...

Generating Continental Scale Pixel-Based Surface Reflectance Composites in Coastal Regions with the Use of a Multi-Resolution Tidal Model

Remote Sensing, 2018
Generating continental-scale pixel composites in dynamic coastal and estuarine environments presents a unique challenge, as the application of a temporal or seasonal approach to composite generation is confounded by tidal influences.

Ukrainian spiritual song of oral tradition : research state and perspectives

Opera slavica, 2023
The author attempts to define approaches that would allow a large-scale study of the spiritual song as a phenomenon of folk tradition. For this purpose, "a top view" is formed, so to speak, from a modern point of view on the history and state of ...
