Opis:: We consider optimization problems with a small implicitly denned feasible region, and with an objective function corrupted by irregularities, e.g. small noise added to the function values. Known mathematical programming methods with high convergence rate can not, lie applied to such problems. A hybrid technique is developed combining random search for the feasible region of a considered problem, and evolutionary search for the minimum over the found region. The solution results of two test problems and of a difficult real world problem are presented.

Opis:: A randomized method aimed at evaluation of probabilistic bounds for function values is considered. Stochastic intervals tightly covering ranges of function values with probability close to one are modelled by a randomized method inspired by interval arithmetic. Statistical properties of the modelled intervals are investigated experimentally. The experimental results are discussed with respect to application of this method in the construction of a branch and bound type randomized algorithm for global optimization.

Opis:: Algorithms based on statistical models compete favorably with other global optimization algorithms as proved by extensive testing results. Recently, techniques were developed for theoretically estimating the rate of convergence of global optimization algorithms with respect to the underlying statistical models. In the present paper these technictues are extended for theoretical investigation of P-algorithms without respect to a statistical model. Theoretical estimates may eliminate the need for lengthy experimental investigation which previously was the only method for comparison of the algorithms. The rcaults obtained give new insight into the role of the mnderlying statistical model with respect to the asymptotic properties of the algorithm which will be useful for the implementation of new versions of the algoritlmns.

Opis:: The aim of this study was to detect Mycoplasma species in the respiratory tract of 110, 310 and 510 day-old groups of cattle by serological, bacteriological and histopathological investigations. Antibodies against M. bovis were found in 75% of the 110 day-old, in 50% – of the 310 day-old and in 55% – of the 510 day-old groups of cattle. Bacteriological examination of the samples from nasal cavities revealed that Mycoplasma carriers were found in 60% of the 110 day-old group of cattle, 40% of the 310 day-old and 40% of the 510 day-old group of cattle. Using the PCR method Mycoplasma was isolated from 25% of lung samples of the 510 day-old group of cattle. Mycoplasma bovis and Mycoplasma dispar were confirmed by serological investigations. Foci of bronchointerstitial pneumonia were determined by histopathological examination in 27.5% of lung samples. Mycoplasma bovis was isolated in 72.7% of bronchointerstitial pneumonia cases. Data processing with an SPSS 13.0 statistical package led to the conclusion that Mycoplasma bovis was found more frequently in the 110 day-old group of cattle (the youngest age group in this study) rather than in the 310 and 510 day-old groups of cattle (χ2 = 6.531; p = 0.038). The results obtained led to the conclusion that serological, bacteriological and histopathological examinations are important in detecting particular animal – carriers of Mycoplasma.

Opis:: Integrated investigations of the Lithuanian coast of the Baltic Sea were carried out in 1999-2004 in order to satisfy an increased demand for information about the shoreline. The area of investigations included the beach and the protective dune or cliff (i.e. an onshore belt 100-300 mwide) and reached 15-20 misobaths in the offshore region. This study has resulted in the Geological Atlas of the Lithuanian coast of the Baltic Sea, which consists of digital maps including a geological-geomorphological map, a map of anthropogenic load at a scale of 1:5000 and an explanatory note. Data arrays from shoreline geodynamic monitoring and from field and analytical studies as well as descriptions of borehole sections are provided in graphic and textual annexes. On basis of these investigations 92 morpholithological profiles of the offshore zone and 101 geological cross-sections of the onshore zone were prepared. The basic geological information in the form of maps and special data arrays allows assessment of the current geological condition of the Baltic Sea shores and enables forecasts for their development. It also can be used for environmental protection and land use in the shoreline area: prevention of erosion, designing of protected, recreation and urban areas, as well as substantiation and development of a seashore monitoring system.
