The dielectric susceptibility measurements are usually interpreted in terms of the relaxation times of various dynamical processes. Using the simple examples of the simulated spectra it is shown how the distribution of these relaxation times can be obtained by means of the integral equations solved with the Tikhonov regularization technique, and the criteria for the choice of the regularization...

Zusammenfassung A Note on the ART of Relaxation. The ART algorithm, an iterative technique for solving large systems of linear equations, is shown to converge even for inconsistent systems, provided the relaxation parameters are chosen appropriately. The limit is a weighted least squares solution. AMS Subject Classifications: 65FI0, 15A09, 92A07.

The link between the energy surface of bulk systems and their dynamical properties is generally difficult to establish. Using the activation-relaxation technique, we follow the change in the barrier distribution of a model of amorphous silicon as a function of the degree of global relaxation. We find that while the barrier-height distribution, calculated from the initial minimum, is a unique fu...

results the results showed that compared to the control group, relaxation (23.2) and positive self-talk (21.25) treatment methods alone can reduce pms (p < 0.001). on the other hand, a combined (relaxation + positive self-talk) treatment method (13.75) was more effective in reducing pms compared to relaxation or positive self-talk alone. conclusions it seems that psychological therapy based on ...

a bstract  background: pregnancy may be accompanied by serious physiological and psychological changes as it is a stressful period in a woman’s life. so, this study was conducted to determine the effect of progressive muscle relaxation on pregnant women’s general health.   materials and methods: in this clinical trial, 60 primigravida women admitted to the prenatal clinic of selected hospitals ...

conclusion in breast cancer after nac, the lesion t2 relaxation time was reduced in the responders, and this finding is potentially useful to assess the response to nac. results in 26 cases with nac, the mean lesion t2 relaxation time before nac was 81.34 ± 13.68 ms, compared with 64.50 ± 8.71 ms after nac. significant differences in the lesion t2 relaxation times existed between the pre- and p...

When variables of constraints of an 0−1 Integer Linear Program (ILP) is replaced by a weaker constraint such that each variable belongs to the interval [0, 1] (i.e. decimal) instead of fixed values {0, 1} (integers); then this relaxation generates a new Linear Programming problem. For example, the constraint xi ∈ {0, 1} becomes 0 ≤ xi ≤ 1. This relaxation technique is useful to convert an NP-ha...

In this paper, we present the derivation of the multiparametric disaggregation technique by Teles et. al (2001) for solving nonconvex bilinear programs. Both upper and lower bounding formulations corresponding to mixed-integer linear programs are derived using disjunctive programming and exact linearizations, and incorporated into two global optimization algorithms that are used to solve biline...

Spielberger's State-Trait Anxiety Inventory ( STAI) and Shostrom' s Personal Orientation Inventory (POI) were completed by three groups of undergraduates at the University of New England at Armidale, Australia, a few days prior to either beginning a program of Transcendental Meditation (TM group, N = 25), a parallel program of progressive relaxation (PR group, N =40), or acting as controls (N =...
