TL;DR: If it turns out that random measures have their fuzzy meanings then this paper presents a way to deal with fuzzy measures of fuzzy sets by use of a classical mathematical method, such as measure theory, functional analysis and topology.

TL;DR: The four principles for determining the fuzzy membership relation are established and it is proved that the unique fuzzy membership relation is exactly the Q-relation which determines theQ-neighborhood structure.

TL;DR: In this paper, the use of electron paramagnetic resonance (EPR) in the study of defects in semiconductors is briefly reviewed, including group IV (C-diamond, Si, Ge, SiC), III-V (AlSb, GaAs, GaSb and GaP), II-VI (BaO, BaS, BeO, CaO,CaS, CaS,CaSe, CdO, MgO, SrO, SENS, ZnC, ZnsS, InP, InSb),
Abstract: The use of electron paramagnetic resonance (EPR and ENDOR) in the study of defects in semiconductors is briefly reviewed, including group IV (C-diamond, Si, Ge, SiC), III-V (AlSb, GaAs, GaSb, GaP, InAs, InP, InSb), II-VI (BaO, BaS, BeO, CaO, CaS, CaSe, CdO, CdS, CdSe, CdTe, MgO, SrO, SrS, ZnC, ZnS, ZnSe, ZnTe) and miscellaneous systems. The identification of defects via EPR is described as is the exploitation of that identification as a tool in future studies. Particular attention is paid to Si. In the category of defect identification in silicon there is emerging an integrated panorama of identified defects ranging from point defects to their complexes and aggregates to so-called intermediate defect configurations on to dislocations and stacking faults. In addition impurities and their interactions are discussed, including mention of a possible origin of the so-called oxygen shallow donor and of the understanding of hydrogen in silicon. As examples of EPR studies as a tool in defect studies the concentration dependence of the phosphorus resonance is described from the regime of isolated defects to the metallic regime. The ENDOR results on defects in silicon are discussed at some length, and it is emphasized that even for the shallow donors there is far from a satisfactory theoretical treatment of the data, and that the situation is even worse for other defects in silicon.

TL;DR: In this article, the stabilization of a certain class of control problems, which require the controls to have only a finite number of values, is approached by quasi-dynamical system theory.
Abstract: This paper concerns the stabilization of a certain class of control problems, which require the controls to have only a finite number of values. The problem is approached by quasi-dynamical system theory. A stabilization strategy is given for the vibrating beam cantilevered at one end and with the control force restricted to have a finite number of values.

TL;DR: The fundamental concept of a fuzzy set, introduced by Zadeh in 1965, provides a natural foundation for treating mathematically the fuzzy phenomena which exist pervasively in the real world and for building new branches of fuzzy mathematics.
Abstract: The fundamental concept of a fuzzy set, introduced by Zadeh in 1965 [34] provides a natural foundation for treating mathematically the fuzzy phenomena which exist pervasively in our real world and for building new branches of fuzzy mathematics. In the area of fuzzy topology much research has been carried out since 1968 [1].

TL;DR: In this article, a class of more general contractive type mappings was defined, and two fixed point existence theorems for these mappings were derived, and they were compared to (25) contractive types defined by B.E. Rhoades.
