in this paper, we introduce and characterize fuzzy wea-kly $e$-closed functions in fuzzy topological spaces and the relationship between these mappings and some properties of them are investigated.

somewhat inaccessible; the present posting is the original version, with a few subsequent references appended. Abstract A simple unified closed form derivation of the non-linearities of the Einstein, Yang-Mills and spinless (e.g., chiral) meson systems is given. For the first two, the non-linearities are required by locality and consistency; in all cases, they are determined by the conserved cu...

The situation is somewhat different when the aligned rectangles are replaced by similar copies of a given convex polygon. More precisely, suppose that 0 is a distribution of N points in the unit square U ̄ [0, 1]#, treated as a torus. Suppose that AXU is a closed convex polygon of diameter less than 1 and with centre of gravity at the origin O. For every real number r satisfying 0% r% 1 and ever...

Research work on price making mechanisms in computational intelligence still remains somewhat under-represented, in part because of its short-time scale implications, and in part due to the complexity in modeling bid-offer array books and correlating them to individual market players. Here we report a study on the transaction cost – trading volume correlations in an artificial stock market with...

The ergodic capacity of various fading channels such as Rayleigh and Rician fading channels has been studied for a long time [1], [2]. Some closed-form expressions of the fading channel capacity have been obtained in terms of a higher transcend function of Meijer’s G function [3] or triple summations of the Poisson distribution [2]. Unfortunately, those representations are somewhat complex and ...

System identification is an important area in process control and statistics. Identification of transfer function parameters provides significant benefits for research and in the design of closed-loop control systems. Despite over six decades of research and applications of system identification, only a handful of methods are currently available. Most current methods are somewhat complex and th...

We described preliminary work on designing a “robot engineer”. Somewhat similar to the idea of a robot scientist, the robot engineer is a closed-loop system that designs tools for a robot, and even complete robots, that are tested in simulation, manufactured and realised using 3D printing. The artefact is then evaluated on real-world tasks, feeding back to the original design. The system builds...

Several studies of peripartum haemodynamics in normal pregnancies have been performed.1-3 The results, however, are somewhat confusing, probably because of methodological factors and the use of indirect methods to assess haemodynamic variables.3 We are aware of only one study on peripartum haemodynamics in parturients with mitral stenosis in which a pulmonary artery catheter was used, but measu...

in this paper, we give a generalization of the integral dependence from rings to modules. we study the stability of the integral closure with respect to various module theoretic constructions. moreover, we introduce the notion of integral extension of a module and prove the lying over, going up and going down theorems for modules.

introduction: nausea and vomiting are the most common complications after minor head trauma that increases the risk of intracranial pressure rising. therefore, the present study was aimed to compare the antiemetic effects of metoclopramide and ondansetron in the treatment of post-traumatic nausea and vomiting. methods: the study was a controlled, randomized, double blind clinical trial, which w...
