Structuring elements of fixed shape and size are used in most conventional mathematical morphology operations, which makes the border of image targets shift, produces new image artifacts and loses small image objects due to the diversity and complexity ...

On Sums of Sets of Primes with Positive Relative Density [PDF]
In this paper we show that if $A$ is a subset of the primes with positive relative density $\delta$, then $A+A$ must have positive upper density $C_1\delta e^{-C_2(\log(1/\delta))^{2/3}(\log\log(1/\delta))^{1/3}}$ in $\mathbb{N}$.

Lattice Structure Design Method Aimed at Energy Absorption Performance Based on Bionic Design
To obtain the lattice structure with excellent energy absorption performance, the structure of loofah inner fiber is studied to develop bionic design of lattice structure by experiment and simulation analysis method. From the compression experiment about

Projection Pursuit through $\Phi$-Divergence Minimisation [PDF]
Consider a defined density on a set of very large dimension. It is quite difficult to find an estimate of this density from a data set. However, it is possible through a projection pursuit methodology to solve this problem.

Copper/Titanium Dioxide (CuTiO _2 ) samples were fabricated at three temperatures (450 °C, 650 °C, 850 °C) using: a universal testing machine (quasi-statically at the strain rate of 8 × 10 ^–3 s ^−1 ), a drop Hammer (dynamically at the strain rate of ...

Inferring the Coronal Density Irregularity from EUV Spectra [PDF]
Understanding the density structure of the solar corona is important for modeling both coronal heating and the solar wind. Direct measurements are difficult because of line-of-sight integration and possible unresolved structures.

Microvesicles were isolated from the conditioned media of 3 cell lines (MDA-MB-231, AsPC-1 and A375) by ultracentrifugation at a range of relative centrifugal forces, and the tissue factor (TF) protein and activity, microvesicle number, size distribution

Experimental investigation on evolution process of suffusion in gap-graded cohesionless soil
The suffusion involves selective erosion and gradual migration of fine particles through the voids of soil skeleton formed by coarse particles under seepage flow. As a result, redistribution of soil skeleton stress and deformation of soil may be induced.
