A novel fuzzy controller is proposed here to improve the positioning precision of servo system of CNC lathes. To utilize the high–accuracy potential of the VUD fuzzy controller, a grating–ruler was used as a sensor to measure the displacement of work pieces. Designing the VUD fuzzy controller involved five steps, i.e., setting up universes of discourse and parameters, selecting membership funct...

In this paper we establish some fixed point theorems for Generalized Contraction mappings in complete fuzzy 2-metric space which are the extension of some known result of many authors. 1 Introduction In 1965, the concept of fuzzy set was introduced initially by Zadeh [11] since then many authors have expansively developed the theory of fuzzy sets and applications. Especially Deng [1], Ereeg [2]...

Matrix descriptions of higher dimensional spherical branes are investigated. It is known that a fuzzy 2k-sphere is described by the coset space SO(2k+1)/U(k) and has some extra dimensions. It is shown that a fuzzy 2k-sphere is comprised of n k(k−1) 2 spherical D(2k − 1)-branes and has a fuzzy 2(k − 1)-sphere at each point. We can understand the relationship between these two viewpoints by the d...

The long slender retinal cones of fishes shorten in the light and elongate in the dark. Light-induced cone shortening provides a useful model for stuying nonmuscle contraction because it is linear, slow, and repetitive. Cone cells contain both thin (actin) and thick (myosinlike) filaments oriented parallel to the axis of contraction. This study examines the polarities of the cone's thin filamen...

Two siblings with a distal motor neuropathy experienced cramping and difficulty in relaxing their muscles after voluntary contraction. Electromyographic recordings at rest revealed repetitive high voltage spontaneous electrical discharges that were accentuated after voluntary contraction and during ischaemia. Regional neuromuscular blockage with curare indicated hyperexcitability of peripheral ...

In the setting of fuzzy metric spaces (FMSs), a global optimization problem (GOP) obtaining distance between two subsets an FMS is solved by tripled fixed-point (FP) technique here. Also, weak contractions (WTCs) for that are given. This was known before in space (MS) as proximity point (PPP). The result correct each continuous τ—norms related to FMS. Furthermore, non-trivial example illustrate...

The present paper aims to introduce the concept of weak-fuzzy contraction mappings in graph structure within context fuzzy cone metric spaces. We prove some fixed point results endowed with a using contractions. By relaxing continuity condition involved, our enrich and generalize well-known theory. With help new lemmas, proofs are straight forward. furnish validity findings appropriate examples...

In this paper, we define and study the Perov fuzzy metric space topology induced by space. We prove Banach contraction theorems. Moreover, devised new results for Kramosil Michálek spaces. process, some about multidimensional common fixed points as coupled/tripled point are derived from our main results.

We consider the relaxed and contraction-proximal point algorithms in Hilbert spaces. Some conditions on the parameters for guaranteeing the convergence of the algorithm are relaxed or removed. As a result, we extend some recent results of Ceng-Wu-Yao and Noor-Yao.

BACKGROUND Patellar tendinopathy is a common condition affecting the posterior region of the proximal patellar tendon, but the reason for this typical location remains unclear. HYPOTHESIS The posterior region of the proximal patellar tendon is subjected to greater tendinous forces than is the corresponding anterior region. STUDY DESIGN Descriptive laboratory study. METHOD An optic fiber t...
