Predictor Design of a Novel Grey Model PGM21 Using Pseudo Second-Order Information

JSME International Journal Series C, 2006
A novel grey model, called pseudo-GM(2,1) or PGM21 for simplicity, is developed to improve the prediction accuracy for a non-monotone sequence by modifying the GM(1,1) model with a remedial term. Since the remedial term consists of two development coefficients, it can be treated as a kind of second-order information, called the pseudo second-order ...

Imaginary Chemical Potential Approach for the Pseudo-Critical Line in the QCD Phase Diagram with Clover-Improved Wilson Fermions [PDF]

, 2011
The QCD phase diagram is studied in the lattice QCD simulation with the imaginary chemical potential approach. We employ a clover-improved Wilson fermion action of two-flavors and a renormalization-group improved gauge action, and perform the simulation ...

Study of kinetic and adsorption isotherm of ibuprofen on mcm-41 synthesized with rice husk [PDF]

Pharmaciana
Rice husk is one of the abundant wastes, especially in agricultural countries. Rice husk waste has a silica content of 95.80%, where the silica content can be utilized to make an adsorbent. One of the adsorbents that can be made is Mobil Composition of

Dynamic Approach to Weak First Order Phase Transitions

, 2000
A short-time dynamic approach to weak first order phase transitions is proposed. Taking the 2-dimensional Potts models as examples, from short-time behaviour of non-equilibrium relaxational processes starting from high temperature and zero temperature ...

First-order scaling near a second-order phase transition: Tricritical polymer collapse [PDF]

, 1999
The coil-globule transition of an isolated polymer has been well established to be a second-order phase transition described by a standard tricritical O(0) field theory.

Isotherm and Kinetics of Fe(II) Adsorption onto Chitosan in a Batch Process [PDF]

Iranica Journal of Energy and Environment, 2011
In this study removal of Fe(II) by chitosan adsorbent was experimentally investigated in a batch system. The adsorbent dose and pH of the metal solution was fixed at 0.15 g and 4, respectively.

Second-Order Pseudo-Hermitian Spin-1/2 Bosons

Universe
The canonical quantization of a field theory for spin-1/2 massive bosons that satisfy the Klein–Gordon equation is presented. The breakdown of the usual spin–statistics connection is due to the redefinition of the dual field, rendering the theory pseudo ...

Nijenhuis Integrability for Killing Tensors [PDF]

, 2016
The fundamental tool in the classification of orthogonal coordinate systems in which the Hamilton-Jacobi and other prominent equations can be solved by a separation of variables are second order Killing tensors which satisfy the Nijenhuis integrability ...
