Genetic structure, relationship and diversity were analyzed in Croatian autochthonous breeds, Turopolje pig (CATP, 48 samples) and Black Slavonian pig (CABS, 28 samples), using 14 microsatellite loci. As traditionally those breeds are kept in the outdoor system, we also analyzed potential admixture with local wild pigs, Lonjsko polje National Park area (WBLP, 20 samples) and Djakovo area (WBDJ, 20 samples), as well as a wild pig population from Island Cres (WBCI, 20 samples) representing an out-group. A posterior Bayesian approach implemented in the program STRUCTURE indicating existence of two autochthonous (CATP & CABS) and two wild pig populations [WBNP (WBLP & WBDJ) & WBCI] with low level of admixture between domestic and wild populations. The lowest differentiation was estimated between WBNP and CABS (FST=0.154) as well as between WBNP and WBCI (FST=0.159). In contrast, CATP was rather differentiated from CABS (FST=0.240), from WBNP (FST=0.292) and from WBCI (FST=0.429). High allele richness [total number of alleles (AT)] and diversity [expected heterozygosity (He)] was observed in WBNP [AT=7.1, He=0.67] and CABS [AT=6.4, He=0.72] populations while much lower values were observed in CATP [AT=5.6, He=0.49] and WBCI [AT=3.5, He=0.49]. In conclusion, the results obtained indicated urgent need for the effective conservation program for CATP population.

In this paper we presents process of UML modeling for algorithm which is used in computational geometry and computer graphics. Implementation of algorithm for triangulation polygon is given in programming language JAVA. The main motivation is to present a way of solving problems through so-called visual planning and programming using object-oriented concepts. Dynamic and static model processing show the problem and give the plan for solving and implementation in some of objective-oriented program language. In one section of this paper we will list some research of authors and their results in the application of programming languages in the field of computer graphics. We specify reason for programming in Java in computer graphics and compared with other programming languages.

The paper deals with one of frequently encountered tasks in process industry - water level control. Proportional Integral Derivative (PID) control is often used for this purpose. Since control parameters of PID controller are fixed and tank system is inherently nonlinear, PID controller should not be used on wider level range. Therefore, this paper analyzes the effectiveness of water level control using fuzzy controller. The fuzzy controller is implemented based on mathematical model of tank and using MATLAB. The controller is implemented on Friendly ARM - embedded computer. Arduino board is used as an acquisition board for collecting sensor data from tank system Festo Didactic DD 3100 and as a PWM signal generator for water pump control. Experimental results confirm that the fuzzy control system has good adaptability in comparison with PID and provided satisfying results.
