Parameter sensitivity analysis can determine the influence of input parameters on model output. Identification and calibration critical are crucial points process optimization. Based Extended Fourier Amplitude Sensitivity Test (EFAST) Morris method, this paper analyzes compares parameter annual mean net primary productivity (NPP) Larix olgensis Henry forests in Jilin Province simulated by Lund–...

In the present study, the effective parameters of water-Al2O3 nanofluid flowing in flat tubes are investigated using the EFAST Sensitivity Analysis (SA) method. The SA is performed using GMDH type artificial neural networks (ANN) which are based on validated numerical data of two phase modeling of nanofluid flow in flat tubes. There are five design variables namely: tube flattening (H), flow ra...
Maintenance task prioritization is essential for a production system, especially in the case of limited available resources. In this paper, overall line efficiency (OLE), which comprehensively evaluates productivity and processability, adopted as objective to develop maintenance prioritization. An OLE centred policy proposed, assigns priorities according influences specific characteristics equi...
BACKGROUND Ultrasound is widely considered the initial diagnostic imaging modality for trauma. Preliminary studies have explored the use of trauma ultrasound in the prehospital setting, but the accuracy and potential utility is not well understood. OBJECTIVE We sought to determine the accuracy of trauma ultrasound performed by helicopter emergency medical service (HEMS) providers. METHODS T...
We present ultraviolet, optical, near-infrared photometry and spectroscopy of SN 2009N in NGC 4487. This object is a Type II-P supernova with spectra resembling those of subluminous II-P supernovae, while its bolometric luminosity is similar to that of the intermediateluminosity SN 2008in. We created SYNOW models of the plateau phase spectra for line identification and to measure the expansion ...
