Thermo-acoustic systems can convert thermal energy into acoustic waves and vice-versa. This conversion is due to the thermo-viscous interaction between acoustically oscillating gas fluid within a porous medium, referred as regenerator, pore internal walls. The thermo-acoustic approach proposed in this study an alternative sustainable solution for addressing issue of electricity remote areas dev...

The desiccant air conditioning system consists of two processes, namely cooling and dehumidification, in which the temperature humidity are controlled order to provide comfortable thermal conditions. A typical includes a dehumidifier, indirect evaporative cooler, regenerator. is selected depending on its ability absorb water vapor present air. In this study, calcium chloride solution was used a...

We propose and numerically investigate a phase regeneration technique that allows an M-PSK signal to be phase regenerated by an M/2-PSK (or even M/4-PSK) phase regenerator (applicable for M = 2, with k an integer). This scheme comprises three main parts; firstly, phase harmonic generation is used to create the second and third phase harmonics, secondly, the second phase harmonic (a down-convert...

The causes and the prevention of carbon steel corrosion in amine systems are reviewed. The corrosive agents are acid gases, oxygen, heat stable salts, amine degradation products, and, in refineries, gas contaminants such as ammonia and hydrogen cyanide. Corrosion mechanisms are provided for carbon steel exposed to amine solutions and for amine regenerator overhead systems containing aqueous con...

Introduction. In this letter we report briefly the result of a measurement of the mass difference Am = mLms, where mL and ms are the masses of the long and short lived neutral kaons respectively. The experimental details will be presented more completely elsewhere. The method consists of the comparison of the intensity of the KS regenerated from a K, beam in two slabs of matter separated at dif...
