Abstract: The transcritical cycle of carbon dioxide (CO2) is a promising alternative approach to heat pumps and automobile air conditioners. As an expansion device, the short tube orifice in a transcritical ...

Abstract: Surge oscillations in a differential surge chamber have two degrees of freedom and are characterized by nonlinearities. The linear approximation provides stability criteria for small perturbations around the equilibrium ...

Abstract: In numerous infrastructure health monitoring and inspection applications, swift and precise three-dimensional reconstruction of subsurface objects from ground penetrating radar (GPR) data is of critical importance, ...

Abstract: A new neural network modeling approach to the evaporator performance under dry and wet conditions has been developed. Not only the total cooling capacity but also the sensible heat ratio and ...

Abstract: Adiabatic capillary tubes and short tube orifices are widely used as expansive devices in refrigeration, residential air conditioners, and heat pumps. In this paper, a generalized neural network ...

Abstract: The multilevel mixing method for aggregate gradation design was optimized based on the division of the functions of coarse and fine aggregates. The mixing procedures were simplified. The mixing process for fine aggregates ...

Abstract: The nature of congested traffic flow has been not fully understood until now. An isolated bottleneck on the expressway generally influences a limited segment length, which means attenuation effects of the bottleneck on ...
