In this paper, we enlarge the language of triangle algebra by addinga unary operation that describes properties of a state. Thesestructure algebras are called state triangle algebra. The vitalproperties of these algebras are given. The notion of state interval-valued residuated lattice (IVRL)-filters are introduced and givesome examples and properties of them are given. ...

The concepts of deconfinement and topological order are great current interest for quantum information science our understanding materials. Here, we introduce a simple model three antiferromagnetically coupled Kondo impurities, triangle, which can be used to further extend the application these electronic systems. We show that, by tuning magnetic frustration, triangle undergoes phase transition...

In this work we introduce a new method for representing and evolving snakes that are constrained to lie on a prescribed surface (triangle mesh). The new representation allows to automatically adapt the snake resolution to the surface tesselation and does not need any (unstable) back-projection operations. Furthermore, it enables efficient and robust collision detection and gives us complete con...

In this paper we introduce a simple and efficient scheme for encoding the connectivity and the stripification of a triangle mesh. Since generating a good set of triangle strips is a hard problem, it is desirable to do this just once and store the computed strips with the triangle mesh. However, no previously reported mesh encoding scheme is designed to include triangle strip information into th...

Polyhedral models, which are used in most graphics applications, require considerable amounts of storage, even when they only approximate precise shapes with limited accuracy. To support internet access to 3D models of complex virtual environments or assemblies for electronic shopping, collaborative CAD, multi-player video games, scientific visualization, representations of 3D shapes must be co...

Given a set of pairwise distances on a set of n points con structing an edge weighted tree whose leaves are these n points such that the tree distances would mimic the original distances under some criteria is a fundamental problem For example this problem is sometimes called the heirarchical clustering problem One distance preservation criterion is to preserve the total order of pair wise dist...

Many interesting geometric structures on manifolds can be interpreted as structures locally modelled on homogeneous spaces. Given a homogeneous space (X,G) and a manifold M , there is a deformation space of structures on M locally modelled on the geometry of X invariant under G. Such a geometric structure on a manifold M determines a representation (unique up to inner automorphism) of the funda...

For graphs G and H, G is said to be H-free if G has no induced subgraph isomorphic to H. For integers s and t with 1 ≤ s ≤ t, let Bs,t be a graph obtained by attaching each of some two distinct vertices of a triangle to an end vertex of one of two vertex-disjoint paths of orders s and t. In this paper, we prove that every 3-connected Bs,9−s-free line graph is Hamiltonian for an integer s with 1...

It is known that the correlator of one axial and two vector currents, that receives leading contributions through one-loop fermion triangle diagrams, is not modified by QCD radiative corrections at two loops. It was suggested that this non-renormalization of the 〈V V A〉 correlator persists in higher orders in perturbative QCD as well. To check this assertion, we compute the three-loop QCD corre...
