A REGULARITY THEORY FOR OPTIMAL PARTITION PROBLEMS
Symmetry and Perturbation Theory, 2005The purpose of this paper is to present some recent results concerning the main qualitative properties of the solutions of several problems connected with optimal partition questions. The object of the theory is the so called class S, introduced by the authors in in the following manner. First, let N 2 2, R c RN be a connected] open bounded domain with

The Optimization Theory of File Partition in Network Storage Environment
2010 Ninth International Conference on Grid and Cloud Computing, 2010The instability of the network and storage nodes may lead to the failure of the storage process in the network storage environment. In this paper, we establish the realibility model of the storage node availability, and the probability model of a success file block storage process, give the Store-After-Partition Strategy, compare the probabilities of a

Optimized partitioning in Rayleigh–Schrödinger perturbation theory
Chemical Physics Letters, 1999Abstract Finite-order perturbation corrections are ambiguous since they depend on the partitioning of the Hamiltonian to a zero-order part and perturbation, and any chosen partitioning can be freely modified, e.g. by level shift projectors. To optimize low-order corrections, an approximate variational procedure is proposed to determine level shift ...

Optimizing QoS partition based on threshold-crossing theory
2009 4th International Conference on Computer Science & Education, 2009With the advent of various QoS technologies, various traffic classes with different QoS requirements are supported on an integrated IP network. As for the multiservice IP networks, the dominant factor in the cost of provisioning a particular service is dependent on the minimum network bandwidth allocated in the network with QoS requirements satisfied ...

Optimized partitioning in perturbation theory: Comparison to related approaches
The Journal of Chemical Physics, 2000A generalized Epstein–Nesbet type perturbation theory is introduced by a unique, “optimal” determination of level shift parameters. As a result, a new partitioning emerges in which third order energies are identically zero, most fifth order terms also vanish, and low (2nd, 4th) order corrections are quite accurate.

The Journal of Chemical Physics, 2003
A multireference perturbation method is formulated, that uses an optimized partitioning. The zeroth-order energies are chosen in a way that guarantees vanishing the first neglected term in the perturbational ansatz for the wave function, Ψ(n)=0. This procedure yields a family of zeroth-order Hamiltonians that allows for systematic control of errors ...

Evaluating Sphagnum traits in the context of resource economics and optimal partitioning theories
Oikos, 2020Tradeoffs between key aspects of plant performance such as resource acquisition and allocation underpin several trait‐based theories that have been derived for vascular plants. However, due to difficulty in quantifying traits in nonvascular plants, our theoretical understanding of how traits govern the physiological and ecological ...

High-order multireference perturbation theory is applied to the $^{1}$S states of the beryllium atom using a reference (model) space composed of the |1${\mathit{s}}^{2}$2${\mathit{s}}^{2}$〉 and the |1${\mathit{s}}^{2}$2${\mathit{p}}^{2}$〉 configuration-state functions (CSF's), a system that is known to yield divergent expansions using Mo/ller-Plesset ...
