Establishing correspondences between two minutia sets is a fundamental issue in fingerprint recognition. This paper proposes a new tensor matching strategy. First, the concept of minutia tensor matrix (simplified as MTM) is proposed. It describes the first-order features and second-order features of a matching pair. In the MTM, the diagonal elements indicate similarities of minutia pairs and no...

Let $S$ be a dense subsemigroup of $(0,+infty)$. In this paper, we state   definition of thick near zero, and also  we will introduce a definition that is equivalent to the definition of piecewise syndetic near zero which presented by Hindman  and Leader in [6].  We define density near zero for subsets of $S$ by a collection of nonempty finite subsets of $S$ and we investigate the conditions un...

Rechargeable magnesium batteries (RMBs) have been considered a promising energy-storage device due to their high energy density and safety, but they still suffer from lack of high-rate performance cycle the cathode. Nanosized CuCo2S4/Cu7.2S4 composites synthesized for first time by facile solvothermal method. Herein, ion storage behavior when applied in cathode RMBs is discussed. Electrochemica...

ZrW 2 O 8 is known as a negative coefficient of thermal expansion (CTE) material. In contrast, the studies other properties than CTE , such conductivity and mechanical properties, are limited. Herein, highly dense bulk sample (%T.D. > 95%) from very fine powder (D50 0.3 μm) with crystalline size 31 nm using spark plasma sintering (SPS) technique synthesized. It revealed that exhibits lowest ...

The changes of the surface morphology and chemistry LSC thin films grown on different substrates were tracked for 100 hours under SOFC operation conditions. Atomic force microscopy was used to monitor formation particles at surface. Depending film structure (polycrystalline vs. epitaxial), particle dynamics observed. Electron employed investigate segregated revealed that Sr- S-rich. Secondary i...
