Vnútrozemskou vodnou nákladnou dopravou sa z ropných produktov prepravujú hlavne nafta a benzín. Na území Slovenska je ako dopravná cesta využívaná rieka Dunaj s prístaviskom v Bratislave, pomocou ...ktorej riečne člny prepravujú tovar do zahraničných prístavov. Prednosťou využívania tohto druhu dopravy je nízke environmentálne zaťaženie a taktiež cena za prepravu. Medzi nevýhody patrí závislosť na prírodných podmienkach (hladina vody) a čas prepravy.
The arrangement of nonzero entries of a matrix, described by the graph of the matrix, limits the possible geometric multiplicities of the eigenvalues, which are far more limited by this information ...than algebraic multiplicities or the numerical values of the eigenvalues. This book gives a unified development of how the graph of a symmetric matrix influences the possible multiplicities of its eigenvalues. While the theory is richest in cases where the graph is a tree, work on eigenvalues, multiplicities and graphs has provided the opportunity to identify which ideas have analogs for non-trees, and those for which trees are essential. It gathers and organizes the fundamental ideas to allow students and researchers to easily access and investigate the many interesting questions in the subject.

U ovom istraživanju izvagano je 150 matica nakon izlijeganja uzgajanih iz presađenih jednodnevnih ličinki. Cilj istraživanja bio je utvrditi korelaciju mase izlegnutih matica s veličinom matičnjaka ...mjereći volumen, širinu i dubinu matičnjaka. Prosječna masa izlegnutih matica iznosila je 206,14 ± 28,25 mg, najmanja utvrđena masa iznosila je 121,30 mg, dok je najveća iznosila 260,70 mg. Najveća pozitivna korelacija (r (150) = 0,597) utvrđena je između mase matice i volumena matičnjaka, dok je najmanja korelacija utvrđena sa širinom matičnjaka (r (150) = 0,335). Na osnovu dobivenih rezultata može se zaključiti kako veličina matičnjaka značajno utječe na veličinu matice. Iako su iz većih matičnjaka dobivene teže matice, odstupanja je ipak bilo poput izlijeganja lakših matica iz većih matičnjaka i obrnuto.
In this study, 150 queens grafted from day-old larvae were weighed after hatching. The aim of the study was to determine the correlation of the hatched queens body mass with the size of the queen cells by measuring the volume, width and depth of the queen cells. The average body mass of atched queens was 206.14 ± 28.25 mg. The lowest recorded body mass was 121.30 mg, while the highest was 260.70 mg. The highest positive correlation (r (150) = 0.597) was found between queen body mass and queen cell volume, while the lowest correlation was found with queen cell width (r (150) = 0.335). Based on the results, it can be concluded that the size of the queen cell significantly affects the body mass of the queen. Although heavier queens were obtained from larger queen cells, the deviations were noted, such as smaller body mass queens hatching from larger queens and vice versa.
This book presents the state of the art in sparse and multiscale image and signal processing, covering linear multiscale transforms, such as wavelet, ridgelet, or curvelet transforms, and non-linear ...multiscale transforms based on the median and mathematical morphology operators. Recent concepts of sparsity and morphological diversity are described and exploited for various problems such as denoising, inverse problem regularization, sparse signal decomposition, blind source separation, and compressed sensing. This book weds theory and practice in examining applications in areas such as astronomy, biology, physics, digital media, and forensics. A final chapter explores a paradigm shift in signal processing, showing that previous limits to information sampling and extraction can be overcome in very significant ways. Matlab and IDL code accompany these methods and applications to reproduce the experiments and illustrate the reasoning and methodology of the research are available for download at the associated web site.
