In this paper, we propose a new multi-scale connected coherence tree algorithm (MCCTA) by improving the connected coherence tree algorithm (CCTA). In contrast to many multi-scale image processing algorithms, MCCTA works on multiple scales space of an image and can adaptively change the parameters to capture the coarse and fine level details. Furthermore, we design a Multi-scale Connected Cohere...

We carefully examine two mechanisms--coherence resonance and self-induced stochastic resonance--by which small random perturbations of excitable systems with large time scale separation may lead to the emergence of new coherent behaviors in the form of limit cycles. We analyze what controls the degree of coherence in these two mechanisms and classify their very different properties. In particul...

The modern physician is using pharmaceuticals as his prime tool. Unfortunately, this tool is much less efficient than you might expect from the biochemical theory. The belief in drugs as the solution to the health problems of mankind, overlooking important existing knowledge on quality of life, personal development, and holistic healing seems to be one good reason why approximately every second...

An analytical model derived from normal mode theory for the accumulated effects of range-dependent multiple forward scattering is applied to estimate the temporal coherence of the acoustic field forward propagated through a continental-shelf waveguide containing random three-dimensional internal waves. The modeled coherence time scale of narrow band low-frequency acoustic field fluctuations aft...

Shared memory provides an attractive and intuitive programming model for large-scale parallel computing, but requires a coherence mechanism to allow caching for performance while ensuring that processors do not use stale data in their computation. Implementation options range from distributed shared memory emulations on networks of workstations to tightly coupled fully cache-coherent distribute...

Background: Job performance is one of the most fundamental concepts in organizations, based on which, the responsibilities and success of each individual in the organization are formed.  The main objective of the current study was to investigate the mediating role of perceived organizational support in the relationship between sense of coherence (SOC) and professional ethics, and the job perfor...

In this paper, a new robust orientation estimation for Coherence Enhancement Diffusion (CED) is proposed. In CED, proper scale selection is very important as the gradient vector at that scale reflects the orientation of local ridge. For this purpose, a new scheme is proposed in which pre calculated orientation, by using orientation diffusion, is used to find the correct true local scale. From t...
