PROMISING QUANTUM ENGINEERING OF OPTICAL EVEN/ODD SCHRÖDINGER CAT STATES
We propose an efficient way to implement new family of continuous variable (CV) states of definite parity. Measurement induced CV states of definite parity states are realized after subtraction of an arbitrary number of photons from the initial single-mode squeezed vacuum (SMSV) state using a...

THE CRITICAL VENTILATION VELOCITY FOR TRANSVERSE DOUBLE FIRES IN TUNNEL
The critical velocity of longitudinal ventilation is one of the most important parameters in tunnel fires. Most previous studies simulated fire scenarios in which only one fire source exists in the tunnel. However, the critical velocity will change under the condition of transverse double fires. In ...

THE PERIODIC TEMPERATURE OSCILLATIONS IN A CYLINDRICAL PROFILE WITH A LARGE THICKNESS
A hollow cylinder with thick walls is one of the most complex objects to calculate the unsteady temperature field, so this field is the least studied. However, such objects are found in many modern constructions of systems of generation and distribution of heat. In the proposed work it deals with...
