1. Equipment for Monitoring Synchronous Generators Condition through External Magnetic Field Waveforms
Abstract This paper presents an equipment for monitoring synchronous generators condition through characteristics of the time derivative of the external magnetic field. The developed monitoring methodology allows the identification of established or incipient faults, by detecting changes in the magnetic signature of the synchronous generator. In this methodo

2. Modelagem de processos de negócio: efeito do método de notação no nível de ambiguidade
Resumo A proposta deste estudo experimental controlado e aleatorizado foi analisar a especificação de requisitos funcionais. Avaliaram-se os possíveis impactos do método de notação de modelagem de processo no nível de ambiguidade presente na especificação em linguagem natural. As notações foram utilizadas como instrumento para manifestar as nece

3. Error variance of short duration sieving
Abstract In this study, the variance of ordinary sieving test error was determined concerning the specification limit of sized iron ore product by subtracting the fundamental error (described by the Gy's formalism for sampling), from the global error (recoverable from database of historical values). The results allowed the calculation of the confidence inter

4. Modification of thermal and rheological behavior of asphalt binder by the addition of an ethylene-methyl acrylate-glycidyl methacrylate terpolymer and polyphosphoric acid
Abstract This study evaluated the modification effects of adding ethylene-methyl acrylate-glycidyl methacrylate terpolymer (EMGMA) in the presence of polyphosphoric acid (PPA) to an asphalt binder graded as 50/70 (0.1mm) in the Brazilian penetration grade specification (AC 50/70). The EMGMA terpolymer has been presented as a new alternative to modify asphalt

5. Water sorption and solubility of bulk-fill composites polymerized with a third generation LED LCU
Abstract The aim of this study was to compare the degree of water sorption and solubility in bulk-fills after curing with a polywave light source. A total of 120 disc-shaped specimens (8 mm diameter; 4 mm depth) were prepared from three regular bulk-fill materials (X-tra Fil, Tetric N-Ceram Bulk Fill, SonicFill), and a control material (Filtek Z250), cured i

6. Evaluation of the physicochemical properties of silicone- and epoxy resin-based root canal sealers
Abstract To assess the physicochemical properties of AH Plus, GuttaFlow 2, GuttaFlow BioSeal, and MM Seal, five samples of each root canal sealer were evaluated to determine their setting time (ST), dimensional change (DC), solubility (SL), flow (FL), and radiopacity (RD) according to American National Standards Institute/American Dental Association (ANSI/AD

7. Management Process of a Frequency Response Flight Test for Rotorcraft Flying Qualities Evaluation
ABSTRACT This paper applies the frequency response methodology to characterize and analyze the flying qualities of longitudinal and lateral axes of a rotary-wing aircraft, AS355-F2. Using the results, it is possible to check the suitability of the aircraft in accordance with ADS-33E-PRF standard, whose flying qualities specifications criteria are based on pa

8. Effects of hematite surface characteristicson filtration process
Abstract In iron ore pelletizing plants a range of process parameters such as particle size distribution, specific surface area, and moisture, must be controlled to achieve optimized operation conditions. Particle size distribution and specific surface area are controlled during the grinding operations. Moisture, however, is controlled during filtration of t

9. Biocompatibility and setting time of CPM-MTA and white Portland cement clinker with or without calcium sulfate
Objective To evaluate the biocompatibility and the setting time of Portland cement clinker with or without 2% or 5% calcium sulfate and MTA-CPM. Material and Methods Twenty-four mice (Rattus norvegicus) received subcutaneously polyethylene tubes filled with Portland cement clinker with or without 2% or 5% calcium sulfate and MTA. After 15, 30 and 60 days o

10. Influence of delayed pouring on irreversible hydrocolloid properties
The aim of this study was to evaluate the physical properties of irreversible hydrocolloid materials poured immediately and after different storage periods. Four alginates were tested: Color Change (Cavex); Hydrogum (Zhermack); Hydrogum 5 (Zhermack); and Hydro Print Premium (Coltene). Their physical properties, including the recovery from deformation (n = 3)

12. SOLIMVA: A methodology for generating model-based test cases from natural language requirements and detecting incompleteness in software specifications / SOLIMVA: Uma metodologia para geração de casos de testes baseados em modelos a partir de requisitos em linguagem natural e detecção de não completude em especificações de software
Em maior ou menor extensão, a Linguagem Natural (LN) é ainda amplamente usada para elaborar especificações de requisitos de software ou outros artefatos criados para a documentação de requisitos. Entretanto, fornecimentos elaborados em LN apresentam ambiguidade, inconsistência e não completude. Esta tese de doutorado apresenta uma metodologia, SOLIMV
