IGIS Tech Notes describe workflows and techniques for using geospatial science and technologies in research and extension. They are works in progress, and we welcome feedback and comments below.

From the discovery of gravity to the first mission to defend Earth from an asteroid, here are the most important physics ...

The authors proposed two hypotheses: first, that methamphetamine induces neuroinflammation, and second, that it alters neuronal stem cell differentiation. These are valuable hypotheses, and the ...

Phased antenna arrays are commonly used to determine the Angle-of-Arrival (AoA) of radio signals. However, in cases where limitations on size and weight are a concern, a fresh approach involves using ...

To achieve fast and accurate calculation of the contact angle (CA) between minerals and water, thus saving computing resources, this work took kaolinite, quartz, and montmorillonite as examples and ...

To surmount this challenge, we propose a high-precision angle measurement method based on an annular spot. Through the design of an axicon-based optical system, the incident Gaussian beam is ...
