Wear resistance, oil resistance, morphology and vulcanization performances of ethylene-vinyl acetate/acrylonitrile butadiene rubber composites

open access: yeseXPRESS Polymer Letters, 2019
The composites consisting of ethylene-vinyl acetate rubber (EVM) and acrylonitrile butadiene rubber (NBR) were prepared by two-step blending method, and were reinforced with carbon black (CB) using 1,4-bis(tert-butylperoxyisopropyl) benzene (BIPB) as ...

open access: yesKnowledgeable Research: A Multidisciplinary Journal, 2023
A child's education should not start with the alphabet. He should observe nature and be introduced to natural things. After this knowledge of words should be given. The child should first understand the dedication of word, form, meaning, then understand the similarities and dissimilarities of different words.

Using EVMS with COTS-Based Systems [PDF]

open access: yes, 2002
With the increased use of commercial off-the-shelf (COTS) software products, managers of software development projects must plan and track performance of projects that have new challenges and risks. A system developer may be required to integrate multiple COTS products with newly developed custom components and legacy system components.

Orientation, sphericity and roundness evaluation of particles using alternative 3D representations [PDF]

open access: yes, 2014
Sphericity and roundness indices have been used mainly in geology to analyze the shape of particles. In this paper, geometric methods are proposed as an alternative to evaluate the orientation, sphericity and roundness indices of 3D objects.

Non-equilibrium spatial distribution of Rashba spin torque in ferromagnetic metal layer

open access: yes, 2012
We study the spatial distribution of spin torque induced by a strong Rashba spin-orbit coupling (RSOC) in a ferromagnetic (FM) metal layer, using the Keldysh non-equilibrium Green's function method.

Study on adaptive modulation in D2D communications over Nakagami-m fading channel

open access: yesTongxin xuebao, 2018
A novel adaptive modulation based on nondata-aided error vector magnitude (NDA-EVM) was proposed to solve the problem of lower spectral efficiency in device to device (D2D) communication over Nakagami-m fading channel.The NDA-EVM was used to evaluate the

Faster ASV decomposition for orthogonal polyhedra using the Extreme Vertices Model (EVM) [PDF]

open access: yes, 2000
The alternating sum of volumes (ASV) decomposition is a widely used technique for converting a B-Rep into a CSG model. The obtained CSG tree has convex primitives at its leaf nodes, while the contents of its internal nodes alternate between the set ...

Entanglement verification for quantum key distribution systems with an underlying bipartite qubit-mode structure

open access: yes, 2006
We consider entanglement detection for quantum key distribution systems that use two signal states and continuous variable measurements. This problem can be formulated as a separability problem in a qubit-mode system. To verify entanglement, we introduce
