Skoltech scientists have developed an algorithm that can identify various tree species in satellite images. Their research was published in the
IEEE Journal of Selected Topics in Applied Earth Observations and Remote Sensing.
Identifying tree species is essential for efficient forest management and monitoring. Satellite imagery is an easier and cheaper way to deal with this task than other approaches that require ground observations of vast and remote areas.
Researchers from the Skoltech Center for Computational and Data-Intensive Science and Engineering (CDISE) and Skoltech Space Center used a neural network to automate dominant tree species identification in high and medium resolution images. A hierarchical classification model and additional data, such as vegetation height, helped further enhance the predictions quality while improving the al ....

Mass spectrometers are widely used to analyze highly complex chemical and biological mixtures. Skoltech scientists have developed a new version of a mass spectrometer that uses rotation frequencies of ionized molecules in strong magnetic fields to measure masses with higher accuracy (FT ICR). The team has designed an ion trap that ensures the utmost resolving power in ultra-strong magnetic fields. The research was published in the journal
Analytical Chemistry.
The ion trap is shaped like a cylinder made up of electrodes, with electric and magnetic fields generated inside. The exact masses of the test sample s ions can be determined from their rotation frequencies. The electrodes must create a harmonized field of a particular shape such that the ions rotate predictably. A ....
