Australian indigenous people before and at the time of discovery
No full textV nalogi se ukvarjam z odkritjem Avstralije za Zahod in njeno poselitvijo v prvi polovici 19. stoletja. Zanima me, kako so se do domorodcev vedli Evropejci ter ali se je ta odnos spremenil od zgodnje dobe odkritij. Takrat Evropa okreva po reformaciji, tridesetletni vojni in demografski krizi srednjega veka ter se pomika v dobo absolutističnih vladarjev, renesanse in industrijske revolucije ter predvsem v dobo odkritij. Ko Cook odkrije Avstralijo, tam najde nomade, ki nimajo želje trgovati. Ne vidi njihovega kulturnega življenja, ki je v skladu s Sanjami ohranjal ravnovesje med družbo in naravo. Tam na pobudo britanske vlade ustanovijo kazensko kolonijo, z navodili naj z domorodci vzpostavijo prijateljski odnos. Kaznjenci vseeno širijo naselja in odrivajo Aboridžine v puščavo. Svoja dejanja upravičijo z zakonom terra nullius, plemenitim divjakom, naravnim pravom in naravnim stanjem. Z vzpostavitvijo mreže rezervatov in misijonov so, kot v Severni Ameriki, skušali domorodce asimilirati. Družboslovna teorija razlaga zavračanje tujca s principom drugega. Ta predvideva njegovo prepoznanje, a ne tudi razumevanja, zaradi česar mu je dodeljen status manjvrednega, kar upravičuje nasilje. V primeru poseljevanja Avstralije se pod vplivom humanističnih mislecev britanska vlada zaveda krivičnega ravnanja, a zaradi neučinkovite lokalne uprave, ki je v najnovejšem svetu še v nastajanju, ter potrebe po novem ozemlju to spregleda.Here, I try to explain the colonisation of Australia and the stand the settlers take against Aborigines. I want to know whether the mentality of man changed from the early Age of discovery, where the explorers would violently push indigenous people to the edge of extinction and over, to the 19th century people, the era of renaissance, absolutism and the industrial revolution. Pioneers have argued their superiority on the basis of the terra nullius law, the doctrines of the noble savage, the natural state and the natural law. The British government, as opposed to the self initiative of early seafarers, would establish a penal colony on a newly discovered continent of Terra Australis with instructions to the governor to reconciliate his relationship with the natives. However, he did not have the means of the local government to do so, so the settlers pushed Aborigines out to the dessert. The social theory of the other explains the discovery and the rejection of his equality to self, which made the other inferior
Weighted Sobolev spaces applied to nonlinear Klein-Gordon equation
No full textIn this work we study the decay properties of the semilinear Klein-Gordon equation with nonlinearity of fractional order. By the aid of a suitable generalization of the weighted Sobolev spaces we define the weighted Sobolev spaces on the upper branch of the unit hyperboloid: X = {(t, x) \ t(2) - \x\(2) = 1, t greater than or equal to 1}. In these spaces of fractional order we obtain a weighted Sobolev inequality and a nonlinear estimate. Using these estimates we study the decay property of the solution for large t provided the power of nonlinearity is greater than a critical value. (C) Academie des Sciences/Elsevier, Paris
Comparison of self-organizing maps classification approach with cluster and principal components analysis for large environmental data sets
No full textThree classification techniques (loading and score projections based on principal components analysis (PCA), cluster analysis (CA) and self-organizing maps (SOM)) were
applied to a large environmental data set of chemical indicators of river water quality. The study was carried out by using long-term water quality monitoring data. The advantages of SOM algorithm and its classification and visualization ability for large environmental data sets are stressed. The results obtained allowed detecting natural clusters of monitoring locations with similar water quality type and identifying important discriminant variables
responsible for the clustering. SOM clustering allows simultaneous observation of both spatial and temporal changes in water quality. The chemometric approach revealed different patterns of monitoring sites conditionally named ‘‘tributary’’, ‘‘urban’’, ‘‘rural’’ or ‘‘background’’. This objective separation could lead to an optimization of river monitoring nets and to a better tracing natural and anthropogenic changes along the river stream
Large time behaviour of solutions to the semilinear wave equation in Schwarzschild metric
No full textOn homogeneous Besov spaces for 1D Hamiltonians without zero resonance
No full textWe consider 1-D Laplace operator with short range potential V (x) dacaying sufficiently rapidly.
We study the equivalence of classical homogeneous Besov type spaces and the corresponding perturbed homogeneous Besov spaces associated with the perturbed Hamiltonian on the real line. It is shown that the ssumption zero is not a resonance guarantees that the perturbed and unperturbed homogeneous Besov norms are equivalent. As a corollary, the corresponding wave operators leave classical homogeneous Besov spaces invariant
Modified FVK model
No full text[Georgiev V.; Георгиев В.]This paper considers a generalization of Föppl–von Kärmán model for elastic plate depending on a parameter σ. We prove global well posedness for the Cauchy problem with small initial data and σ = 1 via Strichartz estimate for vibrating plate and Riesz transform. We generalize this result to a perturbed version of the original case (σ = 2) with the use of Yukawa potential. 2010 Mathematics Subject Classification: 35J50, 35Q40, 35J45
