1. Synthesis and Mechanical Reconfiguration of Ground Plane Tilted Microstrip Antennas Based on Tetra-Circle Fractals
Abstract A synthesis procedure of a mechanically reconfigurable antenna based on tetra-circle fractal patch elements is presented, enabling to change both resonant frequencies and radiation pattern performance. The antenna geometry reconfiguration is implemented by tilting the ground plane of the microstrip antenna with respect to the fractal patch and subst

2. Echoendoscopy with elastography in mediastinal lymph nodes
RESUMO A elastografia, procedimento difundido em ultrassonografia convencional, foi recentemente incorporada à ecoendoscopia. Trata-se de tecnologia inovadora e promissora, que visa aumentar o valor preditivo negativo da ultrassonografia endoscópica e das punções aspirativas com agulha fina. É útil para o direcionamento das punções em áreas suspeita

4. Ultrassonografia e CA-125 como preditores de malignidade em mulheres com tumores anexiais / Ultrasonography and CA-125 as predictors of malignancy in women with adnexal tumors
Introduction: Ovarian cancer is the deadliest gynecologic neoplasm and it is the fifth leading cause of cancer-related deaths in women. The survival rate is low, not exceeding 40% after 5 years and is directly related to tumor stage at the time of diagnosis. To date there is still no screening method that is effective at reducing mortality from this neoplasm

6. Estudo dos componentes auxiliares de partida a frio de motores movidos a Diesel / Study of auxiliary components of cold start in Diesel engines
Cold start in Diesel engines is a problem which has not yet been properly solved and becomes particularly critical with the current trend to reduce the emission levels at low temperatures and engine compression ratio addressed to fuel consumption decrease. Although it is clear that there are some key factors whose control leads to a proper cold start process

7. A proposal for optimized analysis of transient currents in conductive materials. / Uma proposta para análise otimizada de correntes transitórias em materiais condutores.
In this work, a methodology is developed, based on the application of the moment method associated to a finite difference approximation, for time domain analysis of transient current distribution in conducting media. The computational procedure allows that long conductors with any cross section can be considered, approximated by filamentary elements. Thus, t

8. Mecanização de central de navegação inercial com dados a partir da integração de IMU MEMS e receptor GPS / Inertial navigation mechanization through the intergration of an IMU MEMS and a GPS receiver.
The proposal of this work is to present a procedure for integration of the acceleration and angular rate measurements of a low cost Inertial Measurement Unit (IMU) based on MEMS (Micro Electro-Mechanical System) technology with position and speed data from a GPS receiver. Then, it details the equations that have been used to integrate the movement and the at

9. Algoritmos de navegação em tempo real para um sistema GPS de posicionamento relativo de precisão / Real time navigation algorithms for a percise GPS relative positioning system
The GPS signal is subject to several error sources in the measurements. The combined effects of these errors in the propagation signal cause a degradation in precision of positioning. However, using carrier phase measurements, it is possible to reduce positioning error up to 100 times, if compared with positioning using code measurernents. However, this type

10. Uma proposta para o controle automático da repartida de poços operando por gas lift contínuo
The gas-lift wells restart process has high complexity. If the procedure is not carefully executed, the production liquid flowrate can show an oscillatory behaviour, called #severe slugs#. This situation is undesirable because it causes productivity loss, decreases oil-watergas separation process performance or can lead to the shutdown of the system. Nowaday

12. Development of low-cost equipment to instrumentalize the ASTM D 1209-00 method / Desenvolvimento de equipamento de baixo custo instrumentalizar o metodo ASTM D 1209-00
The ASTM D1209-00 method describes the procedure for the visual measurement of the color of essentially light colored liquids, which involves the visual comparation between the color of the samples with the color of Pt-Co standards solutions, with concentration from 1 to 500 unities of Pt-Co, the ASTM D 1209-00 scale (solutions obtained by mixing potassium c
