The refrigeration cycle of an air source heat pump system is important information that reveals critical operating data, such as the cooling capacity, power consumption, and performance a during operation. Operating refrigerant pressure enthalpy in situ, can be difficult to measure. Therefore, this study developed situ measurement method using airside data pump. A for measuring proposed charact...

A numerical solution of the modified Burgers' equation (MBE) is obtained by using quartic B-spline subdomain finite element method (SFEM) over which the nonlinear term is locally linearized and using quartic B-spline differential quadrature (QBDQM) method. The accuracy and efficiency of the methods are discussed by computing L 2 and L ∞ error norms. Comparisons are made with those of some earli...

The Data Assimilation Research Testbed (DART) has been extended to be able assimilate the column-average dry-air mole fraction of CO2 (XCO2) retrievals from Orbiting Carbon Observatory 2 (OCO-2) satellite. Atmospheric concentrations over Midwestern United States were estimated by Weather and Forecasting model coupled with Chemistry (WRF-Chem), without assimilating OCO-2 extended-DART. To focus ...

Abstract In the pre-construction phase of offshore wind energy projects floating lidar systems (FLS) are used for site assessment. Their measurements mean speed and direction have proven to be accurate according existing standards. But assessment turbulence intensity (TI), a widely-accepted procedure acceptance criteria missing. This study investigates different evaluation methods, namely linea...

This paper aims to enhance the performance of a cascade-forward neural network (CFNN) model predict output power photovoltaic (PV) module. improvement is conducted by optimizing number hidden neurons using genetic algorithm (GA). The optimization carried out minimize value root mean square error (RMSE) between actual and predicted PV power. CFNN-based GA evaluated five statistical term terms; n...

Coprime arrays enable Direction-of-Arrival (DoA) estimation of an increased number sources. To that end, the receiver estimates autocorrelation matrix a larger virtual uniform linear array (coarray), by applying selection or averaging to physical array's estimates, followed spatial-smoothing. Both and have been designed under no optimality criterion attain arbitrary (suboptimal) Mean-Squared-Er...
