RESUMO Neste trabalho, uma análise comparativa entre as wavelets Gaussianas e Golden é apresentada. Tais wavelets são geradas pela derivada de uma função basica específica. Nesse caso, a ordem da derivada também indica o número de momentos nulos da wavelet. Embora essas wavelets tenham formas de onda muito semelhantes, elas possuem várias características distintas nos domínios do tempo e da frequência. Essas distinções são exploradas aqui no espaço de escalas. A fim de comparar os resultados das wavelets para um sinal real, essas wavelets são usadas na decomposição de um sinal inserido no contexto do sistemas de monitoramento de integridade estrutural.

ABSTRACT In this work, a comparative analysis between Gaussian and Golden wavelets is presented. These wavelets are generated by the derivative of specific base functions. In this case, the order of the derivative also indicates the number of vanishing moments of the wavelet. Although these wavelets have a similar waveform, they have several distinct characteristics in time and frequency domains. These distinctions are explored here in the scale space. In order to compare the results provided by these wavelets for a real signal, they are used in the decomposition of a signal inserted in the context of structural health monitoring.

The political dynamic of Costa Rica in 2009 was focused on three main areas: the impact of the international economic crisis, the discussion over electoral processes, in the lead up to national elections in February 2010 and the follow-ups and new corruption scandals of high authorities. Firstly, the government was primarily focused on the implementation of the 'Anti-crisis' Plan, but was also called upon to direct important efforts in response to unforeseen events, such as the emergency aftermath of the earthquake of 8 January, the AlH1 swine flu pandemic, and in the second half of the year, the request made of President Oscar Arias, to intervene as a mediator in the Honduran crisis. Second, in the elections of February 2010, and under the new Electoral Code, the candidate for the PLN, the party of government, was duly elected President of the Republic with a popular vote of46.9 percent. Por the first time in the country's history, the presidency is held by a woman. Finally, in the area of accountability, in the midst of the electoral campaign, new scandals continued to envelop public servants, including the misuse of state institutions helicopters and planes for personal matters. Of particular note is the culmination of the first judicial process against the Ex-President Rafael Ángel Calderón, who was condemned to five years in prison by a Criminal Court.

La dinámica política de Costa Rica en el 2009 estuvo concentrada en tres grandes arenas: el impacto de la crisis económica internacional y por los procesos electorales con miras a los comicios nacionales de febrero del 2010 y el seguimiento y nuevas manifestaciones de casos de corrupción de altos jerarcas. Primero, las políticas públicas se concentraron en la implementación del Plan anticrisis, denominado Plan Escudo, aunque el gobierno se vio obligado a dirigir importantes esfuerzos a eventos no previstos como lo fueron la emergencia ocasionada por el terremoto del 8 de enero, la gripe Al HI, y, en el segundo semestre, la atención a la crisis hondurena por el golpe de Estado. En segundo lugar, en las elecciones generales de febrero del 2010, y bajo un nuevo el nuevo Código Electoral, aprobado en 2009, resultó electa de manera contundente la candidata del partido de gobierno, Liberación Nacional (PLN). Por primera vez el país tendrá una mujer como Presidente de la República. Y, en tercer lugar, las denuncias por corrupción o falta de transparencias, exacerbadas también por la contienda electoral, pusieron a prueba la institucionalidad de control existente en el país. Destaca en esta área la culminación de la primera instancia del juicio contra el ex presidente Rafael Ángel Calderón, quien fue condenado a cinco años de prisión por un Tribunal penal.
