Abstract: The aim of the presented paper is to understand the latest trends in Internal Combustion Engine while maintaining its prime focus on six stroke engine. The underlying idea to write this paper is to try and implement a 6 stroke engine coupled to an electric motor in hybrid car. This would then be numerically analyzed with existing hybrid cars.

Abstract: New self-oscillatory compressible flows are found and investigated. Self-oscillations are supposed to be produced as a result of resonance interactions of flow “active” elements, namely, elements, amplifying disturbances. Hypothesis is used that contact discontinuities and intersection points of shocks with shocks or shocks with contact discontinui... Show More

Abstract: High Tc lead–free Ba (Zr0.52Ti0.48)O3 positive temperature coefficient of resistivity (PTCR) ceramic was produced by the standard solid state reaction technique. X–ray diffraction pattern confirms the formation of the tetragonal perovskite structure of the ferroelectric sample. The conduction and relaxation mechanisms of the piezoelectric ceramic h...

Abstract: This paper reports a natural ventilation silencer for an animal cage having considerable sound insertion loss. Many veterinary hospitals face a serious problem that hospitalized animals are stressed from the barks of other dogs in the hospital. To address this problem, a solution that barely affects caged dogs’ health is required. First, we estimat... Show More
