1. Frequency Domain Interleaving for Dense WDM Passive Optical Network
Abstract In this work, we introduce a new concept of frequency interleaving applied to passive optical networks based in Dense Wavelength Division Multiplexing (DWDM). In order to explore colorless ONUs approach, a single and centralized optical source is used to create the interleaved wavelengths for the downstream and upstream path. In this case, frequency

3. Water absorption process capability analysis by chicken carcasses during precooling
Abstract Cooling of carcasses using water immersion is the most used process in the poultry industry. In this stage, besides the reduction of temperature, water absorption in the carcasses occurs and, consequently, in the chicken cuts, which are monitored by the companies and supervised by the Ministry of Agriculture, Livestock, and Supply of Brazil, which

4. Costs of genetic testing: Supporting Brazilian Public Policies for the incorporating of molecular diagnostic technologies
This study identifies and describes the operating costs associated with the molecular diagnosis of diseases, such as hereditary cancer. To approximate the costs associated with these tests, data informed by Standard Operating Procedures for various techniques was collected from hospital software and a survey of market prices. Costs were established for four

5. El devenir de la utopía economicista en el sistema escolar chileno
The radical transformations of the Chilean education system carried out by the military dictatorship during the 1980s were designated as an “economist’s utopia” given that they converted an preferably public and centralized system into one governed by the rules of the free market. Under this assumption, we examine the new system’s development, which

6. Rehearsal: Um arcabouço para teste automatizado de coreografias de serviços web / Rehearsal: A framework for automated testing of web service choreographies
Web services are loosely-coupled software components designed to support interoperable machine- to-machine interaction over the Internet. To achieve such interoperability, web services are accesible through W3C web standards, independently of which language, operating system, or hardware platform they are developed. Due to these characteristics, simple web s

7. Uma aplicação de redes definidas por software para a gerência de redes de datacenters virtualizados
Cloud-Computing services related to infrastructure have been drawing much attention recently. On this business model, virtualization is an efficient way to ofier flexibility, isolation and several new functionalities. This technology has led to the multi-tenant datacenter model for Cloud-Computing, where the client (tenant) can rent not only a virtual machin

8. Contribuições para o estabelecimento de estratégias laboratoriais em genética para a saúde pública no Brasil utilizando a síndrome de deleção 22q11.2 como modelo / Contributions to the establishment of laboratory strategies in medical genetics for public health in Brazil, using the 22q11.2 deletion syndrome as a model
The introduction of new technologies of molecular diagnosis for health care has been a challenge in the last years, especially in Brazil, where the majority of the population is served by the public health system. The 22q11.1 deletion syndrome is the most common syndrome that has palatal anomalies as a major feature, with a prevalence of 1/4000 births. Consi

10. O planejamento econômico no Brasil: considerações críticas
In the past thirty years, a series of plans have been developed by successive Brazilian governments in a continuing effort to maximize the nation's resources for economic and social growth. This planning history has been quantitatively rich but qualitatively poor. The disjunction has stimulated Professor Mello e Souza to address himself to the problem of nat

11. Investigação do escoamento bifásico gás-líquido em uma coluna de bolhas retangular por meio da técnica CFD / Investigation of two-phase gas-liquid flow in a rectangular bubble column using CFD technique
This study aims to evaluate the main forces which act in gas-liquid flow in a rectangular bubble column of dimensions 150cm x 26;4cm x 3;1cm (height (H) x width (W) x depth (D)), with centralized aeration, using CFD technique. The proposed case is based in a experimental study of an air-water system operating in homogeneous bubbly flow, with initial liquid h

12. Genetic Algorithm for the solution of majority problem / Algoritmo genÃtico para a soluÃÃo do problema da maioria.
Many natural and social systems exhibit globally organized behavior without the aid of a centralized control. Examples of such decentralized systems include conventions and norms, social learning in animals and humans, as well as fads, rumors and revolts. Examples are also abundant in biology: the evasive behavior of animals in large groups, such as fish and
