Rice-crayfish field (i.e., RCF) distribution mapping is crucial for the adjustment of local crop cultivation structure and agricultural development. The single-temporal images two phenological periods in year were classified separately, then areas where water disappeared identified as RCFs previous studies. However, due to differences segmentation lakes rivers between images, incorrect extracti...

In this paper, we introduce and study the prime, strongly prime,semiprime and irreducible fuzzy bi-ideals of a semigroup. We characterize thosesemigroups for which each fuzzy bi-ideal is semiprime. We also characterizethose semigroups for which each fuzzy bi-ideal is strongly prime.

creativity or uncreativity of the rational soul is one of the oldest problem of philosophy. ibn sina by giving some proofs has proven the creativity of the rational soul. fakhr ad-din ar razi has propsed several critics to each of the avecina’s argument. in this article, we are going to prove that, the origin of razi’s critics is his misunderstanding in ibn sina’s philosophical views in potenti...

Modelling real world problems using rational agents has been heavily investigated over the past two decades. BDI (Beliefs, Desires, and Intentions) Logic has been widely used to represent and reason about rational agency. However, in the real world, we often have to deal with different levels of confidence in the beliefs we hold, desires we have, and intentions that we commit to. This paper pro...

We define parallelograms of base a and b in a group. They appear as minimal relators in a presentation of a subgroup with generators a and b. In a Lie group they are realized as closed polygonal lines, with sides being orbits of left-invariant vector fields. We estimate the number of sides of parallelograms in a free nilpotent group and point out a relation to the rank of rational series. 1 Int...

Miniaturized in-plane π-type thermoelectric devices composed of p-type Mg2Sn0.8Ge0.2 and n-type Bi layers were prepared by microfabrication techniques. Structural effects on device performance need to be evaluated optimized improve operation. In this study, a rational analysis the correction open-circuit output voltages, powers, power densities using effective temperature differences was perfor...
