Context. Galaxy imaging surveys observe a vast number of objects, which are ultimately affected by the instrument’s point spread function (PSF). It is weak lensing missions in particular that aimed at measuring shape galaxies and PSF effects represent an significant source systematic errors must be handled appropriately. This requires high level accuracy modelling stage as well estimation galax...

Incorporating higher-order optimization functions, such as Levenberg–Marquardt (LM) have revealed better generalizable solutions for deep learning problems. However, these functions suffer from very large processing time and training complexity especially datasets become large, in multi-view classification problems, where finding global optima is a costly problem. To solve this issue, we develo...

the acid-base equilibrium of lorazepam was studied by means of potentiometry andmultiwavelengths spectrophotometry. the stoichiometric equilibrium constants were determinedat 25 °c and constant ionic strength 0.1 mol l-1 (nacl). the acidity constants pk1=1.58±0.05and pk2=11.67±0.07 were found by potentiometry, and pk1=1.54±0.02 and pk2=11.61±0.03 bymulti-wavelengths spectrophotometry. potentiom...

-Advanced thin film processing and packaging technologies are employed in the fabrication of new planar thinfilm multifunction thermal converters. The processing, packaging, and design features build on experience gained from prior NIST demonstrations of thin-film converters and are optimized for improved sensitivity, bandwidth, manufacturability, and reliability.

It’s an important evaluation architecture safety standards about personnel emergency evacuation under the fire condition, from the development trend of university gymnasium, it’s relatively rare that based on comprehensive evaluation the multi-functional gymnasium fire conditions personnel emergency evacuation study and there is no mature evaluation model can be applied to practical operation l...
