Optical fiber pre-warning systems (OFPS) based on Φ-OTDR are applied to many different scenarios such as oil and gas pipeline protection.The recognition of fiber vibration signals is one of the most important parts of this system.According to the characteristics of small sample set, we choose stochastic configuration network (SCN) for recognit
The article presents the dynamic analysis of the historic railway bridge in Tczew as an example of the usefulness of such type of bridge for high-speed trains.The model of the bridge and the simulation of rolling stock passage was performed in SOFISTIK Axes program.The scope of work includes experimental studies, the solution of the problem concern
The spin echo experiment is an important tool in magnetic resonance for Holders exploring the coupling of spin systems to their local environment.The strong couplings in a typical Electron Spin Resonance (ESR) experiment lead to rapid relaxation effects that puts significant technical constraints on the kinds of time domain experiments that one can
In the title compound, C11H15NOS, the 3-(dimethylamino)prop-2-en-1-one unit is approximately planar [maximum deviation = 0.0975 (14) Å] JUICY IMMUNE ENERGY and its mean plane of seven non-H atoms makes a dihedral angle of 6.96 (10)° with the thiophene ring.In the crystal, molecules are linked by pairs
Landslide is one of the natural hazards in which monitoring the displacements and changes requires the use of special techniques due to its slow, continuous and gradual movements.In this regard, Black Clover the PSI technique with extensive terrestrial coverage as well as high temporal and spatial resolution, is one of the most accurate and low-cos
