the bakun phase, as one of most significant chalcolithic cultures of fars province attributed basic stage related to socio-economic transformation in early village societies of iran. on the basis of varied archaeological researches regarding bakun phase, revealed relatively homogenous culture on the whole of fars and some its neighbors was characterized by black on buff painted ceramic assembla...

We exactly solve a class of Frenkel-Kontorova models with a periodic potential composed of piecewise convex parabolas having the same curvature. All rotationally ordered stable configurations can be depicted with appropriate phase parameters. The elements of a phase parameter are grouped into subcommensurate clusters. Phase transitions, manifested in the gap structure changes previously seen in...

The correlation outputs of synthetic discriminant function (SDF) filters are constrained in response to training images. In this paper, we establish an analytical connection between the constraint values and resulting correlation filter performance. An interesting result from this analysis is that we show that linear phase correlation peak constraints are attractive. Key–Words: Synthetic discri...

Unitary similarity transformations furnish a simple yet powerful vehicle for generating new classes of joint distributions based on concepts diierent from time, frequency, and scale. These new signal representations focus on the critical characteristics of large classes of signals and, hence, prove useful for representing and processing signals that are not well matched by current techniques. I...

This paper presents a method for counting and classifying vehicles on motorway. The system is based on a multi-camera system fixed over the road. Different features (maximum phase congruency and edges) are detected on the two images and matched together with local matching algorithm. The resulting 3D points cloud is processed by maximum spanning tree clustering algorithm to group the points int...

We determine the zero-temperature quantum phase diagram of a px+ ipy pairing model based on the exactly solvable hyperbolic Richardson-Gaudin model. We present analytical and large-scale numerical results for this model. In the continuum limit, the exact solution exhibits a third-order quantum phase transition, separating a strong-pairing from a weak-pairing phase. The mean-field solution allow...

The q = 10 and q = 200 state Potts models coupled to 2d gravity are investigated numerically and shown to have continuous phase transitions, contrary to their behavior on a regular lattice. Critical exponents are extracted and possible critical behavior for general q-state Potts models coupled to gravity is discussed.

Recent increases in deciduous shrub cover are a primary focus of terrestrial Arctic research. This study examined the historic spatial patterns of shrub expansion on the North Slope of Alaska to determine the potential for a phase transition from tundra to shrubland. We examined the historic variability of landscape-scale tall shrub expansion patterns on nine sites within river valleys in the B...

For models which exhibit a continuous phase transition in the thermodynamic limit a numerical study of small systems reveals a non-monotonic behaviour of the microcanonical specific heat as a function of the system size. This is in contrast to a treatment in the canonical ensemble where the maximum of the specific heat increases monotonically with the size of the system. A phenomenological theo...
