非数值数据（Non-Numerical Data）指的是不能以数值方式表示的数据，它通常是具有分类或描述性质的数据。在计算机科学和编程中，非数值数据是用来表示非数值的信息，如文本、布尔值、日期和时间等。非数值数据可以分为定性数据（Qualitative Data）和定量数据（Quantitative Data）两种类型：定性数

The ability to perceive and to nonverbally quantify the objects of a set (i.e., its numerosity) has been proposed as one important domain-specific precursor for the development of numerical and arithmetic abilities31,32. Two neurocognitive systems have been related to this development: the approx...
Numerical simulations of coupled hemodynamics and leukocyte transport and adhesion inside coronary arteries have been performed. Realistic artery geometries have been obtained for a set of four patients from intravascular ultrasound and angiography image
The power-flow problem in DC networks corresponds to a set of nonlinear non-convex equations that can be solved iteratively using numerical methods [64], [65], while the OPF problem is an optimization problem that can be solved with interior point methods or convex approximations [62], [66]...
The Giesekus model has a non-zero second normal stress difference, which gives rise to the secondary flow in a rectangular channel. Fig. 3 shows the velocity vectors of the secondary flows for Wi=0.5 and 1.0 at Re=50. The Reynolds number has insignificant effects on the secondary flow, sin...
The numerical results of both loading cases (non-eccentric and eccentric) agreed well with the experimental results. The most significant discrepancy between the ultimate experimental and computational shear forces was 11%, referring to the LS06 model (eccentric load) with one plane of symmetry. Reg...

This review highlights various experimental and mathematical modeling strategies to investigate the fate and transport of antibiotics that elucidate antimicrobial selective pressure in aquatic environments. Globally, the residual antibiotic concentrations in effluents from bulk drug manufacturing industries were 30...
