In this paper, we introduced two types of fuzzy stabilizers St R (F) and St ⊕ R (F) of a fuzzy set F and the stabilizer St ∨(F, G) of F with respect to G in IMTL-algebras. We proved that St R (F), St ⊕ R (F) and St ∨(F, G) are fuzzy filters of M. We investigated some properties of the stabilizers. By introducing the ⊗̃ operation of two fuzzy filters, we prove that ⊗̃ and St∨(·, ·) form an adjoint...
Novel power system neural network (ANN) based stabilizers (PSS) are presented. The two ANN-PSS designs are driven by the speed error and its rate of change. Other supplementary Stabilizing signals such as voltage deviation, ezcursion error, and PSS output rate of change are utilized to ensure the best matching between the ANN-PSS design and the optimized conventional analog PSS bench-mark model...
This paper investigated the effects of combining fibers with self-consolidating concrete (SCC). 12 series of test specimens were prepared using three kinds of fibers including steel, polyphenylene sulfide (PPS) and glass fibers with four different volumes fractions and one specimen without fibers as a reference sample. All plans were subjected to fresh concrete tests. For mechanical behavior of...
introduction: to recognize the myelinated nerve fibers of the external capsule in human brain. materials and methods: 10 adult and normal brains (20 hemispheres) from both sexes were studied using 15 mm serial sections in all three cardinal planes after fixation and processing. these sections were stained by klüver - barrera and heidenhain - woelcke methods. results: some fibers from different ...
A one-step synthesis of FePt nanoparticles is reported. The size, composition, and shape of the particles are controlled by varying the synthetic parameters such as molar ratio of stabilizers to metal precursor, addition sequence of the stabilizers and metal precursors, heating rate, heating temperature, and heating duration. An assembly of large (6 nm or greater) FePt nanoparticles, especially...
Let G be a group, let T be an (oriented) G-tree with finite edge stabilizers, and let V T denote the vertex set of T . We show that, for each G-retract V ′ of the G-set V T , there exists a G-tree whose edge stabilizers are finite and whose vertex set is V ′. This fact leads to various new consequences of the almost stability theorem. We also give an example of a group G, a G-tree T and a G-ret...
Method for production and regeneration of Acetobacter pasterianus protoplasts is described. The protoplasts were obtained by treatment of cells with lysozyme in protoplast buffer at pH 8.0 with different osmotic stabilizers. The protoplasts were regenerated on Acetobacter medium with various osmotic stabilizers. Maximum protoplast formation was obtained in protoplast buffer with NaCl (0.5M) as ...
Huang Shu and Tongwen Chen Dept. of Electrical and Computer Engineering University of Calgary Calgary, Alberta, Canada T2N 1N4 [email protected] [email protected] Abstract For a single-machine, in nite-bus power system, several digital robust stabilizers with single-rate and multirate sampling schemes are designed using modern H1 optimization. The digital stabilizers designed have low ...
Model tests were performed with different temperatures and soil stabilizers to investigate the effect of horizontal frost heave force on open tunnels in seasonal frozen regions. Experimental results show that dissipation accelerated increase temperature, data indicate compared without stabilizers, decreased by 10% 15% lignin fiber Huaxia No. 1 stabilizer. It can be concluded inhibitory stabiliz...
