AB  - Many methods have been proposed to detect the originality of an image. One of the most commonly used method, the Copy - move forgery detection (CMFD), is considered here. The contribution of this paper is the application of the new fuzzy distances in clustering using metaheuristics. The family of the used fuzzy distances satisfies the axioms of the fuzzy metric. CMFD method, which includes Variable Neighborhood Search (VNS) and Bee Colony Optimization (BCO) metaheuristics, has been tested and compared with similar methods. The proposed method with the proposed new metric used in this research gave better results than the existing methods. The proposed fuzzy metrics in this paper as well as the problem of $$p-$$median clustering applied to the problem and compared with existing research in this field give better results.

AB  - In this paper we propose a fuzzy neural network prediction approach based on metaheuristics for container flow forecasting. The approach uses fuzzy if–then rules for selection between two different heuristics for developing neural network architecture, simulated annealing and genetic algorithm, respectively. These non-parametric models are compared with traditional parametric ARIMA technique. Time series composed from monthly container traffic observations for Port of Barcelona are used for model developing and testing. Models are compared based on the most important criteria for performance evaluation and for each of the data sets (total container traffic, loaded, unloaded, transit and empty) the appropriate model is selected.

AB  - In this study, in order to establish grain shapes of sintered ceramics, new approach on correlation between microstructure and doped BaTiO3 -ceramics properties based, on Voronoi model and mathematical statistics calculations on fractal geometry, has been developed. BaTiO3-ceramics doped with Yb2O3 (from 0.1 to 1.0wt% of Yb) were prepared by using conventional solid state procedure and were sintered from 1320 degrees C to 1380 degrees C for four hours. The microstructure of sintered specimens was investigated by Scanning electron microscope JEOL-SEM-5300. For better and deeper characterization and understanding of the ceramics material microstructure, the methods which include the fractal nature structure, and also Voronoi model and mathematical statistics calculations, are applied. In our research the Voronoi is one specific interface between fractal structure nature and different stochastically contact surfaces, defined by statistical mathematical methods. Also, the Voronoi model practically provided possibility to control the ceramics microstructure fractal nature. Mathematical statistic methods enabled establishing the real model for the prognosis based on correlation: synthesis-structures-properties.

AB  - Among the modified BaTiO3 La doped BaTiO3-ceramics are intensively studied because of their attractive ferroelectric properties that can be tailored to meet the strong demands for various electroceramic components. In this investigation La/Mn codoped BaTiO3 with different La2O3 content, ranging from 0.1 to 5.0 at% La, was investigated regarding their microstructural characteristics. Microstructural and compositional studies were performed by scanning electron microscopy (JEOL-JSM 5300) equipped with EDS (QX 2000S) system. Depending on the amounts of dopants and sintering temperature a huge range of microstructure features can be observed in doped ceramics, together with the appearances of secondary phases that are formed above eutectic temperature. The morphology of ceramics grains pointed out the validity of developing new structure analytical methods, based on different grains' shape geometries. The new correlation between microstructure of doped BaTiO3-ceramics, based on fractal geometry and contact surface probability, has been developed. Using the fractals and statistics of the grains contact surface, a reconstruction of microstructure configurations, as grains shapes or intergranular contacts, has been successfully done. The directions of possible materials properties prognosis are determined according to the correlations synthesis-structure-property.

AB  - Voltage quality of power supply for three-phased induction motors is defined with value of voltage, voltage asymmetry and harmonic distortion of voltage. In this paper, an influence of voltage quality on energy efficiency of three-phased induction motors has been pointed, with particular review on energy efficiency of induction motors with squirrel-cage rotors in agriculture. Increase of energy efficiency of induction motors is achieved not only with applying energy efficient induction motors, but also with optimization of costs of consumed electrical energy, on which significantly influences the quality of voltage power supply and the choice of optimal value of voltage power supply, considering nominal power, working mode, load and constructive characteristics of induction motors being applied. .
