Formalized Mathematics, 2016 Abstract In this article, using mostly Pervin [9], Kunzi [6], [8], [7], Williams [11] and Bourbaki [3] works, we formalize in Mizar [2] the notions of quasiuniform space, semi-uniform space and locally uniform space. We define the topology induced by a quasi-uniform space.

Journal of Telecommunications and Information Technology, 2001 A parameter study is performed of a broadband uniplanar quasi-Yagi antenna with regard to its design and use in a~spatial power combiner. A 3D full-wave electromagnetic field analysis is applied to identify parameters, which mostly affect the design ...

On precompact (quasi-) uniform structures [PDF]
Proceedings of the American Mathematical Society, 1977 The following are shown: (1) The subbasis theorem on precompactness does not hold even in uniform spaces. (2) The supremum of (even finitely many) precompact quasi-uniform structures is not necessarily precompact. (3) A compact quasi-uniform space is not necessarily totally bounded. These results contradict corresponding assertions in the literature.

Every finite system of T1 uniformities comes from a single distance structure
Applied General Topology, 2002 Using the general notion of distance function introduced in an earlier paper, a construction of the finest distance structure which induces a given quasi-uniformity is given.

Aggregation of L-Probabilistic Quasi-Uniformities [PDF]
Mathematics, 2020 The problem of aggregating fuzzy structures, mainly fuzzy binary relations, has deserved a lot of attention in the last years due to its application in several fields. Here, we face the problem of studying which properties must satisfy a function in order to merge an arbitrary family of (bases of) L-probabilistic quasi-uniformities into a single one ...

Advanced Engineering Materials, EarlyView.A numerical–experimental framework is developed for characterizing multi‐matrix fiber‐reinforced polymers (MM‐FRPs) combining epoxy and polyurethane matrices. Harmonic bending tests are integrated with finite element model updating (FEMU) to simultaneously identify elastic and viscoelastic material parameters.

Quasi uniform convexity—Revisited
Journal of Approximation Theory, 2017 For a Banach space, \(X\) denote by \(\mathcal{BC}(X)\) the family of all nonempty closed bounded subsets of \(X\). For \(A\in \mathcal{BC}(X)\), \(x\in X\) and \(r>0\), put \(r(A,x)=\sup_{a\in A}\|x-a\|\), \(r(A)=\inf_{x\in X}r(A,x)\), \(Z_r(A)=\{x\in X: r(A,x)\leq r\}\), and \(Z(A)=\{x\in X : r(A,x)=r(A)\}\).

Advanced Engineering Materials, EarlyView.A combined experimental–computational framework identifies energy‐dependent laser absorptivity for NiTi in laser powder‐bed fusion, applicable to conduction and transition modes. Single‐track experiments and thermofluid smoothed particle hydrodynamics simulations are coupled through inverse analysis of melt pool geometry.
