27. Competencies of credit cooperatives : an empirical study on a credit cooperative in germany / Competencies of organisations are of vital importance to them, because they represent the drivers of competitiveness of organisation. Resource-based theory as the underlying theory and competence-based-view in particular highlight competencies problem-solving attribute. This is especially relevant for banks, confronted with challenges, linked to technological developments. Currently, banks are faced considerable difficulties due to the financial and economic crisis. Credit cooperatives, on the other hand, have successfully handled the challenges posed by technological developments and also seem to be dealing with the current crisis rather well. This study, therefore, aims at identifying, analysing and describing competencies of a credit cooperative, that may potentially contribute to solve the problems, banks are continuously faced with. The complexity and difficulty of identifying competencies necessitates the application of an interpretive paradigm to this study, which enables the researcher, as well as managers of CCs and banks to dig deeper into and better understand the area of investigation and thus identify, analyse and describe competencies. An extensive literature research, including the elucidation of specific aspects, was conducted and subsequently, a concept developed that facilitated the structuring of the data gained from the empirical study. This empirical study builds on a comprehensive case study, which involved an especially interesting credit cooperative in Germany. The concept, developed from the theoretical research derived from the literature, was applied to the collected data. The applied research technique resulting from the interpretive paradigm supports the significance of the results, as it allows to a step-by-step and thus better understanding of the rules of the game prevalent in the case-study bank.Finally, the results of each step and the rationale of the identified competencies,including the so-called activation power, are presented. Because of this researchs intensity and extension, a valuable framework to identify, analyse and describe the competencies of credit cooperatives can be proposed. Furthermore, the profound insights into the area of investigation, combined with the interesting aspects, linked to the case-study-bank, allowed the researcher to develop additional correlated propositions. Managers of credit cooperatives as well as of other banks can profit from this study. Understanding the basic rules may enhance the possibility of transfetring the results and consequently to discover thus far unexplored potentials and new ideas for navigating through the current challenging situation.
As competências de organizações são de importância vital para elas porque representam o motor de competitividade da organização. A resource-based theory(teoria fundamentado aos recursos) como a teoria subjacente e a competencebased-view (visão fundamentado aos competências) em particular, destacam o atributo de solução do problema de competências

28. Detecção de eventos para monitoração de qualidade de energia elétrica por medidores de faturamento usando a Transformada Wavelet e a Norma Euclidiana Instantânea. / Detection of events for monitoring the quality of billing electronic meters by using Wavelet Transform and the Instantaneous Euclidian Norm.
This work shows the possibility to add new functions for detection and registration of disturbances that affect power quality to electronic billing meters. The widespread installation of these meters in the power network makes this resource a powerful analysis tool. Remote communication channels in these meters create an easy way for reading and registering

The east coast of Brazil, is lined with a chain of mountains where a forest known as Mata Atlântica develops. The vegetation of these mountains, because of its proximity with the coast, is under the influence of the trade winds full of humidity, from the ocean. Originally the forest extended for almost all the coast, from Rio Grande do Norte to the Rio Gran
