Yes / The decision of the High Court in Astron Clinica Limited and others v The Comptroller General of Patents, Designs and Trade Marks(1) in January 2008 by the Honourable Mr. Justice Kitchin aligns the United Kingdom patent office with the European patent office(2), by overturning the practice of rejecting computer programs patents. The importance of this case was confirmed by the practice note released on the 7th of February 2008 by the UK patent office which indicated that the decision would not be appealed. However, the area is by no means settled with the decision in Symbian in March 2008 casting uncertainly on the Astron Clinica decision and the Aerotel/ Macrossan four step test.

To elaborate teaching activities involving astronomical concepts, such as distance, brightness, image manipulation, colors as well as to explain the nature of different objects showing their images in different filters, among others. In the total, we have elaborated four activities that were applied to students of the 6th year of elementary school, high school and undergraduate ones for the Engineering and Pedagogy courses. All activities and the results of their evaluation with students are detailed discussed and analyzed; a teacher guide is also provided. Our results show that in the four activities, the students have a significant learning supporting the use of such methodology. Also, we elaborated two memory games, based on Java platform, with the images of some astronomical objects. The activities are in The Portuguese language, but they can easily be adapted for any other language. This research also made the translation of Aladin to Portuguese. / Este trabalho contempla a an?lise de um estudo de aplica??es, em sala de aula, de estrat?gias e t?cnicas de facilita??o, que utilizem o software Aladin (http://aladin.u-strasbg.fr/) na forma??o de conceitos de Astronomia e possibilidade de desenvolvimento cognitivo, por meio da aprendizagem, consolidando o aprendizado atrav?s do uso de computadores. Conceitos de dist?ncia, brilho, cor, exist?ncia de diferentes tipos de objetos astron?micos, manipula??o de imagens e dados astron?micos, entre outros aspectos, foram tratados em sala de aula e fizeram parte deste trabalho. A pesquisa foi aplicada em diversas etapas do ciclo de aprendizagem escolar, mais especificamente: 6? ano do ensino fundamental, 2? ano do ensino m?dio, alunos de gradua??o em Engenharia e, por fim, uma turma de alunas de Pedagogia, quase todos professores atuantes e, portanto, divulgadores dos conceitos para eles passados. Todas as atividades utilizaram o software Aladin e uma o aplicativo de Observat?rio Virtual, denominado VO-Stat. Como produto, foi elaborado material did?tico com o conte?do das atividades assim como um roteiro voltado para os professores realizarem a aplica??o da atividade para o ensino fundamental, um jogo da mem?ria virtual que trata de Astronomia. A tradu??o do Aladin para a l?ngua portuguesa tamb?m foi realizada nesse trabalho.

The knowledge of its location and properties constitutes a great benefit to the astronomical community. In this dissertation, we present an automatic method for identifying and classifying images of interacting galaxies at low redshifts for the Southern Hemisphere, based on the properties of stellar and interstellar extinction distribution as well as using a pattern recognition software called ?Wndchrm? on images from the 2MASS survey, in the near infrared for the filters: J, H and KS. The training phase was made with images of known interacting galaxies from the Arp &Madore Catalogue, Categories 1 and 2. After training, a validation was performed using images of a region of the sky with 573 square degrees, obtaining a hit of, approximately, 73% in the identification of galaxies identified by visual inspection as interacting. This rate can reach up 88% considering the comparison with previous know galaxy pairs of Category 2 of Arp &Madore Catalogue. The procedure was performed for an area of about 17.836 square degrees of the Southern Hemisphere, finding at least several hundred galaxy pairs as yet uncatalogued. / As gal?xias peculiares interagentes s?o objetos que ainda carecem de maiores estudos. Elas desempenham um papel importante nos processos de forma??o e de evolu??o das gal?xias. O conhecimento de sua localiza??o e propriedades, constitui um grande benef?cio para a comunidade astron?mica. Nesta disserta??o, apresentamos um m?todo autom?tico para identificar e classificar imagens de gal?xias interagentes a baixos redshifts para o Hemisf?rio Sul. Para tal, estabelecemos crit?rios baseados na distribui??o de estrelas e extin??o interestelar, assim como de objetos identificados no Cat?logo de fontes extensas do 2MASS. Usamos um software de reconhecimento de padr?es chamado Wndchrm em imagens do grande levantamento 2MASS no infravermelho pr?ximo para os filtros: J, H e Ks. A fase de treinamento foi feita com imagens de gal?xias interagentes conhecidas, do Cat?logo de Arp&Madore, das categorias 1 e 2. Ap?s o treinamento foi realizada uma valida??o com imagens de uma regi?o do c?u de 573 graus quadrados, obtendo uma taxa de acerto de, aproximadamente 73% na identifica??o de gal?xias previamente identificadas de forma visual como interagentes. Essa taxa aumenta para, aproximadamente 88% levando em conta pares da Categoria 2 previamente identificados no Cat?logo de Arp&Madore como pertencentes ? essa categoria. Executamos, o procedimento para uma ?rea de, aproximadamente 17.836 graus quadrados do Hemisf?rio Sul, encontrando, ao menos, v?rias centenas de pares de gal?xias ainda n?o catalogados.

We have used the Friends of Friends (FoF) algorithm, as the basis of our clustering, with LL (Linking Length) and the minimum value of separation between galaxies, as our parameters. We have used a catalogue with approximately 44 thousand galaxies. After the simulation with six different values of LL, we analysed our clustering by means of the comparison with the obtained one by Tempel et al. (2016). In this comparison, we obtained a similarity of 79%. We also supplemented the validation of our method with an analysis of the silhouette coefficient, obtaining a general coefficient equal to 0.80. We present the characteristics of the groups obtained in our work, their comparison with the obtained one by Tempel et al. (2016) as well as the discussion with the non-grouped galaxies. / Neste trabalho apresentamos um m?todo alternativo para agrupamento de gal?xias, por meio do uso, dos dados de gal?xias dispon?veis em grandes levantamentos astron?micos. Utilizamos o algoritmo FoF, Friends of Friends, como base para o agrupamento, com os par?metros de LL (Linking Length) e o valor m?nimo de gal?xias, em comum para definir a uni?o entre grupos pr?ximos. Utilizamos um cat?logo com aproximadamente 44 mil gal?xias e ap?s a simula??o com seis valores distintos para o LL, e com a compara??o dos respectivos agrupamentos com os obtidos por Tempel et al. (2016), obtivemos, similaridade, de aproximadamente 79%. Complementamos a avalia??o com uma an?lise do Coeficiente se Silhueta, e encontramos agrupamentos com coeficiente geral de 0,80. Apresentamos a discuss?o e caracter?sticas dos grupos obtidos, assim como das gal?xias n?o agrupadas.
