The updated genetic classification of mineral deposits as natural objects, whose origin is ambiguous, is presented. The classification is based on the petrological and lithological principles, which makes it universal. The conditions for the formation of endogenic, exogenic, and metamorphogenic deposits are considered. Endogenous objects are divided into three groups: magmatic, metasomatic and hydrothermal. Sedimentogenetic, diagenetic, and catagenetic rows are distinguished among the exogenous deposits. Metamorph...

In order to determine the effects of strong earthquakes for a given settlement, it is necessary to solve several tasks in a few stages. The first task is identification of the building stock for the surveyed area. The assessment of the effects of strong earthquakes is based on procedures for integration of seismic hazard and seismic vulnerability of the bearing structures of the building stock. The building stock is divided into three main groups, taking into account the specificity of the building and the availab...

The ?Predicting a Pulsar Star? dataset has been investigated in this paper. The pulsars are special neutron stars emitting narrow beams of light with high energy into space. They rotate very rapidly and the signal repeats. Scientists seek periodic radio signals in order to detect these objects. Of course, frequency patterns vary from one star to another. The signal is averaged on a lot of rotations. At the same time a lot of pulsar candidates are just radio noise. There is a lot of objects to check. In this task m...
