In this paper, we provide several Arzelà–Ascoli-type results on the space of all continuous functions from a Tychonoff X into fuzzy sets Rn, (FUSCB(Rn),Hend), which are upper semi-continuous and have bounded support endowed with endograph metric. Namely, obtain positive when is considered to be kr-space C(X,(FUSCB(Rn),Hend)) compact open topology, as well assume that pseudocompact equipped unif...

In this paper, we have proved results similar to Tychonoff's Theorem on embedding a space of functions with the topology pointwise convergence into Tychonoff product topological spaces, but applied function C(X,Y) all continuous from X uniform Y family subsets and (weak) set-open topology. We also investigated following question: how is related algebraic structures (such as groups, rings vector...

This paper describes a set of methods for randomly drawing traces in large models either uniformly among all traces, or with a coverage criterion as target. Classical random walk methods have some drawbacks. In case of irregular topology of the underlying graph, uniform choice of the next state is far from being optimal from a coverage point of view. Moreover, for the same reason, it is general...

We present genetic algorithms (GAs) as a decentralised topology control mechanism distributed among active running software agents to achieve a uniform spread of terrestrial unmanned vehicles (UVs) over an unknown geographical area. This problem becomes more challenging under the harsh and bandwidth limited conditions of military applications. Using only local neighbour information, a GA guides...

In this paper, we present a fast and efficient mesh coarsening algorithm for 3D triangular meshes. Theis approach can be applied to very complex 3D meshes of arbitrary topology and with millions of vertices. The algorithm is based on the clustering of the input mesh elements, which divides the faces of an input mesh into a given number of clusters for clustering purpose by approximating the Cen...

Resonance and wave-propagation problems are known to be highly sensitive towards parameter variations. This paper discusses topology optimization formulations for creating designs that perform robustly under spatial variations for acoustic cavity problems. For several structural problems, robust topology optimization methods have already proven their worth. However, it is shown that direct appl...

We show that if the set of all bounded strongly continuous cosine families on a Banach space X is treated as a metric space under the metric of the uniform convergence associated with the operator norm on the space L (X) of all bounded linear operators on X, then the isolated points of this set are precisely the scalar cosine families. By definition, a scalar cosine family is a cosine family wh...

Wireless body area networks consist of several devices placed on the human body, sensing vital signs and providing remote recognition of health disorders. Low power consumption is crucial in these networks. A new energy-efficient topology is provided in this paper, considering relay and sensor nodes' energy consumption and network maintenance costs. In this topology design, relay nodes, placed ...

We prove that the additive group (E∗, τk(E)) of an L∞-Banach space E, with the topology τk(E) of uniform convergence on compact subsets of E, is topologically isomorphic to a subgroup of the unitary group of some Hilbert space (is unitarily representable). This is the same as proving that the topological group (E∗, τk(E)) is uniformly homeomorphic to a subset of ` κ 2 for some κ. As an immediat...
