The voter model, with mutations occurring at a positive rate α , has a unique equilibrium distribution. We investigate the logarithms of the relative abundance of species for these distributions in d ≥ 2. We show that, as α→ 0, the limiting distribution is right triangular in d = 2 and uniform in d ≥ 3. We also obtain more detailed results for the histograms that biologists use to estimate the ...

Triangular norms in the study of probabilistic metric spaces as a special kind of associative functions defined on the unit interval. These functions have found applications in many areas since then. In this study, we present new methods for constructing triangular norms and triangular conorms on an arbitrary bounded lattice under some constraints. Also, we give some illustrative examples for t...

In this paper we study some properties related to the distribution of membership grades for non-stationary fuzzy sets. We obtain the formulation for the distribution, where the non-stationary fuzzy sets are obtained by generating instantiations about the center values. The two cases considered are for the underlying membership functions as Triangular and Gaussian. The analytical results obtaine...

danehkhoshk anticline is a typical growing anticline in kermanshah province which is located in folded zagros belt. the purpose of this research is to evaluate the effect of tectonic on the triangular facet characteristics, the drainage density and on the drainage pattern formed on anticline. dimensions of triangular facets were determined by means of quickbird satellite images and field works....

<p>This paper addresses the convergence analysis of triangular-based power flow (PF) method in alternating current radial distribution networks. The PF formulation is made via upper-triangular matrices, which enables finding a general iterative formula that does not require admittance matrix calculations. this carried out by applying Banach fixed-point theorem (BFPT), allows demonstrating...

For non-rigid registration, the objects in medical images are usually treated as a single deformable body with homogeneous stiffness distribution. However, this assumption is invalid for certain parts of the human body, where bony structures move rigidly, while the others may deform. In this paper, we introduce a novel registration technique that models local rigidity of pre-identified rigid st...

Nuclear Magnetic Resonance (NMR) T2 measurements can be used directly to estimate petrophysical properties of reservoir rocks such as porosity and irreducible water saturation. They are also sensitive to pore-size distribution enabling the estimation of permeability and potentially capillary pressure. Several methods have been proposed to derive synthetic drainage capillary pressure information...
