Adaptive local basis set for Kohn–Sham density functional theory in a discontinuous Galerkin framework I: Total energy calculation
Electronic structure Kohn–Sham density functional theory Discontinuous Galerkin Adaptive local basis set Enrichment functions Eigenvalue problem
2015/7/14
Kohn–Sham density functional theory is one of the most widely used electronic structure theories. In the pseudopotential framework, uniform discretization of the Kohn–Sham Hamiltonian generally result...
A consistent multi-user framework for assessing system performance
assessing system performance math
2010/11/15
Agreeing suitability for purpose and procurement decisions depend on assessment of real or simulated performances of sonar systems against user requirements for particular scenarios. There may be mul...
Optimization Framework and Graph-Based Approach for Relay-Assisted Bidirectional OFDMA Cellular Networks
Optimization Framework Graph-Based Approach OFDMA Cellular Networks
2010/11/29
This paper considers a relay-assisted bidirectional cellular network where the base station (BS)communicates with each mobile station (MS) using OFDMA for both uplink and downlink. The goal is to impr...
Computing Networks: A General Framework to Contrast Neural and Swarm Architectures
Computing Networks Swarm Architectures Contrast Neural
2010/4/1
Computing Networks (CNs) are defined. These are used to generalize neural and swarm architectures, namely artificial neural networks, ant colony optimization, and particle swarm optimization. The desc...
The traditional set theory is constructed on the steady state, the bivalent logic and the fixed set boundary. However, the development of fuzzy set or rough set inspires us that an element, which memb...
The Extension of Majorization Inequalities within the Framework of Relative Convexity
Relative convexity Majorization Abel summation formula
2008/6/26
Some of the basic inequalities in majorization theory (Hardy-Littlewood-Pólya, Tomic-Weyl and Fuchs) are extended to the framework of relative convexity.
A VRS dimension framework for effective DSS design
Decision Support Systems VRS activities
2010/9/16
A specific Decision Support System (DSS) can actually serve the Vehicle Routing and Scheduling (VRS) activities of any firm that need to pickup or deliver commodities in a daily base. Such systems can...
