1. Modified Ring Power Divider Using Stepped-Impedance Resonator
Abstract In this paper, the design of a modified ring power divider dedicated for wideband communication or measurement systems is presented. The proposed power divider is built by using a conventional ring power divider and an additional Stepped-Impedance Resonator (SIR). The even-odd mode analysis is used to derive the design equations. In order to observe

2. Simulation and Design of a Bandpass Filter Based on Substrate Integrated E-Plane Waveguide
Abstract This paper presents a bandpass filter based on a substrate integrated E-plane waveguide (SIEW) structure for wireless applications, at X-band. The SIEW geometry allows the development of new horizontally polarized filter topologies, unlike filter structures based on substrate integrated waveguide (SIW), which present vertical polarization (perpendic

3. A Implantação do Sistema de Monitoramento e Avaliação da Secretaria Estadual de Saúde do Distrito Federal (SES/DF)
Resumo Por meio da criação do Sistema Único de Saúde (SUS), os processos de planejamento ganham importância intrínseca para a formulação de políticas públicas de saúde e para subsidiar a tomada de decisões, a implementação de ações e a obtenção de resultados. Como as ferramentas de planejamento são fundamentais para orientar a gestão, é

4. Análise Acústica de Fachadas de Light Steel Frame e Placas Cimentícias
RESUMO A construção a seco tem sido considerada uma alternativa tecnológica aos sistemas construtivos convencionais e, no Brasil, sistemas como o Light Steel Frame e Drywall passaram a ser empregados em maior escala nos últimos anos. Basicamente, estes sistemas consistem em painéis estruturados por perfis de aço, preenchidos internamente por uma lã de

5. Flow Analysis: Looking Back and Forward
Flow analysis changed significantly the way of performing chemical analysis by (i) mechanization of analytical procedures in a continuous flowing stream with minimal sample intercontamination; (ii) analytical measurements without attaining chemical equilibria, thus increasing the applicability of kinetic methods and allowing the exploitation of non-quantitat

6. A System Based on Artificial Neural Networks for Automatic Classification of Hydro-generator Stator Windings Partial Discharges
Abstract Partial discharge (PD) monitoring is widely used in rotating machines to evaluate the condition of stator winding insulation, but its practice on a large scale requires the development of intelligent systems that automatically process these measurement data. In this paper, it is proposed a methodology of automatic PD classification in hydro-generato

7. Performance evaluation of digital TV and LTE systems operating in the 700 MHz band under the effect of mutual interference
Abstract This paper presents results of the assessment of the interference between digital TV systems and LTE systems operating in adjacent bands in the 700 MHz frequency range. Measurement results are presented and used to validate a simulation tool that allows different scenarios of interference between the SBTVD systems and LTE to be created. The simulati

8. Sustainability performance measurement with Analytic Network Process and balanced scorecard: Cuban practical case
Abstract The recent years has arisen a global discussion in relation with how to incorporate sustainability at a business level. Corporate sustainability is a multidimensional concept, is the translation of Sustainable Development concept at a business level. Sustainability in organizations must be managed and assessed by decision makers, for that reason a m

9. Automatic pain quantification using autonomic parameters
The objective measurement of subjective, multi-dimensionally experienced pain is a problem for which there has not been an adequate solution. Although verbal methods (e.g., pain scales and questionnaires) are commonly used to measure clinical pain, they tend to lack objectivity, reliability, or validity when applied to mentally impaired individuals.

10. State estimation of chemical engineering systems tending to multiple solutions
A well-evaluated state covariance matrix avoids error propagation due to divergence issues and, thereby, it is crucial for a successful state estimator design. In this paper we investigate the performance of the state covariance matrices used in three unconstrained Extended Kalman Filter (EKF) formulations and one constrained EKF formulation (CEKF). As bench

11. Evaluation of flow rate accuracy and pressure measurements of testing rig for neurological valve hydrodynamic tests
INTRODUCTION: Increased production and disorders in the circulation or absorption of cerebrospinal fluid (CSF) leads to increased intracranial pressure and causes a condition called hydrocephalus. The most common treatment for this disorder is the implantation of a ventricle-peritoneal shunt, which consists of the insertion of a ventricular catheter in the c

12. Indicadores de mensuração de desempenho em pequenas e médias empresas (PMEs): estudo no setor calçadista de Santa Catarina / Indicators of performance measurement in small and medium enterprises (SMEs): a study in the shoe sector de Santa Catarina
Para competir em um mercado global as organizações precisam, além de formular e implementar estratégias, adotar ferramentas de gestão para monitorar e controlar o desempenho do negócio e comunicar suas ações junto aos seus stakeholders. Diante disso, nos últimos 20 anos, os pesquisadores passaram a examinar e propor sistemas de mensuração de desem
