This paper presents a part of the results obtained by the Process Control group of the Politehnica University of Timisoara, Romania, in the field of evolving Takagi-SugenoKang fuzzy models. These results concern the development of Takagi-Sugeno-Kang fuzzy models by incremental online algorithms for the description of the dynamics or static behavior of three technical and non-technical system applications, namely magnetic levitation systems, Anti-lock Braking Systems and automated translation.

Background:Self-leadership is an important theme in a whole vital work environment, this is because it insists to prepare nurses to lead themselves strongly and develop self-leadership traits. So, for producing such things healthcare institutions have to enable them to face challenges, integrate physical experiences to enhance practice and clinical competencies. Aim:It is to evaluate nurses’ selfassessment of their selfleadership traits. Method:A demographic questions and the Self-Leadership Questionnaire was distributed after conducting the training program to gather data about nursing staff’ self-leadership assessment.Results:It was found that there was a highly significant statistical difference (P= 0.001) between staff nurses’ knowledge pre and post implementing self-leadership training program related to all questions of test, and there was a significant statistical difference appeared regarding all of the self-leadership traits and nurses’ responses post implementation of the ...

Oxides RNiO3 (R = rare-earth, R ≠ La) exhibit a metal-insulator (MI) transition at a temperature TMI and an antiferromagnetic (AF) transition at TN. Specific heat (CP) and anelastic spectroscopy measurements were performed in samples of Nd1−xEuxNiO3, 0 ≤ x ≤ 0.35. For x = 0, a peak in CP is observed upon cooling and warming at essentially the same temperature TMI = TN ∼ 195 K, although the cooling peak is much smaller. For x ≥ 0.25, differences between the cooling and warming curves are negligible, and two well defined peaks are clearly observed: one at lower temperatures that define TN, and the other one at TMI. An external magnetic field of 9 T had no significant effect on these results. The elastic compliance (s) and the reciprocal of the mechanical quality factor (Q−1) of NdNiO3, measured upon warming, showed a very sharp peak at essentially the same temperature obtained from CP, and no peak is observed upon cooling. The elastic modulus hardens below TMI much more sharply upon w...

A new lattice Boltzmann (LB) model is introduced, based on a regularization of the pre-collision distribution functions in terms of the local density, velocity, and momentum flux tensor. The model dramatically improves the precision and numerical stability for the simulation of fluid flows by LB methods. This claim is supported by simulation results of some 2D and 3D flows.

The MnCoGe alloy can crystallize in either the hexagonal Ni2In- or the orthorhombic TiNiSi-type of structure. In both phases MnCoGe behaves like a typical ferromagnet with a second-order magnetic phase transition. For MnCoGeBx with B on interstitial positions, we discover a giant magnetocaloric effect associated with a single first-order magnetostructural phase transition, which can be achieved by tuning the magnetic and structural transitions to coincide. The results obtained on the MnCoGe-type alloys may be extensible to other types of magnetic materials undergoing a first-order structural transformation and can open up some possibilities for searching magnetic refrigerants for room-temperature applications.

Ni (II) is one of most hazardous heavy metal present in industrial effluents the study was carried to test the use of Diplocyclos palmatus seed as adsorbent for Ni (II) removal from aqueous solution. Batch adsorption method was used and the concentration of Ni (II) measured using an ultraviolet-visible (UVVis) spectrophotometry. The effect of contact time, adsorbent dosage, pH, initial metal ion concentration was studied. The data showed that adsorption on Diplocyclos palmatus seed fitted well to Langmuir isotherm. Pseudo-second order model explains the nickel kinetics more effectively. Reusability of the adsorbent was examined by desorption in which HCl eluted 93 % nickel. The results revealed that nickel is considerably adsorbed on Diplocyclos palmatus seed and it could be an economic method for the removal of nickel from aqueous solutions.

Recent measurements of the four-point correlation function in large-scale galaxy surveys have found apparent evidence of parity violation in the distribution of galaxies. This cannot happen via dynamical gravitational effects in general relativity. If such a violation arose from physics in the early Universe it could indicate important new physics beyond the standard model, and would be at odds with most models of inflation. It is therefore now timely to consider the galaxy trispectrum in more detail. While the intrinsic four-point correlation function, or equivalently the trispectrum, its Fourier counterpart, is parity invariant, the observed trispectrum must take redshift-space distortions into account. Although the standard Newtonian correction also respects parity invariance, we show that subleading relativistic corrections do not. We demonstrate that these can be significant at intermediate linear scales and are dominant over the Newtonian parity-invariant part around the equality scale and above. Therefore when observing the galaxy four-point correlation function, we should expect to detect parity violation on large scales.

We present a thorough investigation of the effect ofnoise (internal or extemal) on the synchronization of a drive-response configuration system (unidirectional coupling between two identIcal systems). Moreover, since in every practical implementation of a communication system, the transmitter and receiver circuits (although identical) operate under slightly different conditions it is essential to consider the case of the mismatch between the parameters of the transmitter and the receiver. In OUT work we consider the non-autonomous 2nd order non-linear oscillator system presented by G. Mycolaitis, et aZ in Pmc. onth Int. Workshop on Non-linear Dynamics ofElectronic Systems, which is particularly suitable for digital communications.
