Structural relaxation in silicate melts and non-Newtonian melt rheology in geologic processes [PDF]
, 1989 The timescale of structural relaxation in a silicate melt defines the transition from liquid (relaxed) to glassy (unrelaxed) behavior. Structural relaxation in silicate melts can be described by a relaxation time, , consistent with the observation that ...

Convex Relaxation Methods for Community Detection [PDF]
Statistical Science, 2021 This paper surveys recent theoretical advances in convex optimization approaches for community detection. We introduce some important theoretical techniques and results for establishing the consistency of convex community detection under various statistical models. In particular, we discuss the basic techniques based on the primal and dual analysis. We

A Review of Time Relaxation Methods
Fluids, 2017 The time relaxation model has proven to be effective in regularization of Navier–Stokes Equations. This article reviews several published works discussing the development and implementations of time relaxation and time relaxation models (TRMs), and how ...

Relaxation strategy for the Landweber method [PDF]
Signal Processing, 2016 The Landweber iteration is a general method for the solution of linear systems which is widely applied for image reconstructions. The convergence behavior of the Landweber iteration is of both theoretical and practical importance. By the representation of the iterative formula and the convergence results of the Landweber iteration, we derive the ...

Relaxed Alternating Projection Methods [PDF]
SIAM Journal on Optimization, 2008 In this paper we deal with the von Neumann alternating projection method $x_{k+1}=P_{A}P_{B}x_{k}$ and with its generalization of the form $x_{k+1}=P_{A}(x_{k}+\lambda _{k}(P_{A}P_{B}x_{k}-x_{k}))$, where $A,B$ are closed and convex subsets of a Hilbert space $\mathcal{H}$ and $\operatorname{Fix}P_{A}P_{B}\neq \varnothing$.

Cultural relaxation methods for minor mental health disorders
Sri Lanka Journal of Psychiatry, 2013 Traditional techniques used to produce relaxation can promote and maintain wellbeing in healthy individuals too. They can prevent illnesses including minor mental health disorders from developing in those faced with psychosocial problems by countering ...

On SOR Waveform Relaxation Methods [PDF]
SIAM Journal on Numerical Analysis, 1997 Consider the system of linear ordinary differential equations (ODEs) \(B\dot u(t)+Au(t)=f(t)\), \(u(0)=u_0\), where the matrices \(B, A\) belong to \({\mathbb{C}}^{d\times d}\) and \(B\) is supposed to be nonsingular. The paper deals with the acceleration of the standard waveform relaxation (WR) method by successive overrelaxation (SOR) techniques when
