13. Bonding stability of adhesive systems to eroded dentin
This in vitro study evaluated the immediate and 6 months microshear bond strength (µSBS) of different adhesive systems to sound and eroded dentin. Sixty bovine incisors were embedded in acrylic resin and ground to obtain flat buccal dentin surfaces. Specimens were randomly allocated into two groups: sound dentin (immersion in artificial saliva) and eroded d

14. A novel method for EMG decomposition based on matched filters
Introduction Decomposition of electromyography (EMG) signals into the constituent motor unit action potentials (MUAPs) can allow for deeper insights into the underlying processes associated with the neuromuscular system. The vast majority of the methods for EMG decomposition found in the literature depend on complex algorithms and specific instrumentation.

15. Ground reaction forces during level ground walking with body weight unloading
Background: Partial body weight support (BWS) systems have been broadly used with treadmills as a strategy for gait training of individuals with gait impairments. Considering that we usually walk on level ground and that BWS is achieved by altering the load on the plantar surface of the foot, it would be important to investigate some ground reaction force (

16. Antifungal activity of topical microemulsion containing a thiophene derivative
Fungal infections have become a major problem of worldwide concern. Yeasts belonging to the Candida genus and the pathogenic fungus Cryptococcus neoformans are responsible for different clinical manifestations, especially in immunocompromised patients. Antifungal therapies are currently based on a few chemotherapeutic agents that have problems related to eff

17. Interventions for preventing obesity in children
BACKGROUND: Prevention of childhood obesity is an international public health priority given the significant impact of obesity on acute and chronic diseases, general health, development and well-being. The international evidence base for strategies that governments, communities and families can implement to prevent obesity, and promote health, has been acc

18. Compiler Optimizations Impact the Reliability of the Control-Flow of Radiation-Hardened Software
ABSTRACT: This paper discusses how compiler optimizations influence software reliability when the optimized application is compiled with a technique to enable the software itself to detect and correct radiation-induced control-flow errors. Supported by a comprehensive fault-injection campaign using an established benchmark suite in the embedded systems domai

19. Coplanar waveguide-fed ultra-wideband planar antenna with WLAN-band rejection
A compact coplanar waveguide (CPW)-fed ultra-wideband (UWB) antenna is proposed with band-notched characteristic. The antenna has compact size of 29 x 31 mm². A novel wide polygon-slot is inserted on the antenna to obtain good impedance matching and wide bandwidth. A tapered radiating patch is placed inside the polygon-slot. An embedded C-slot in the radiat

20. Arquitetura escalável de alto desempenho para atualização, acesso e recuperação de informações em bancos de dados de aplicações embarcadas
O gerenciamento remoto de múltiplos sistemas tais como máquinas operatrizes, veículos, aviões, dentre outros, demanda um fluxo bastante intenso de dados entre eles e o sistema gerenciador. Pesquisas têm sido desenvolvidas na concepção e implementação de arquiteturas escaláveis que atendam essas demandas levando a questões interessantes de desempen

21. Geração de b-splines via FPGA / B-spline generation via FPGA
The b-splines are used in CAD/CAM/CAE systems to represent and define complex curves and surfaces, being adopted by the main computer graphics standards due to features like compact mathematic representation, flexibility and affine transformations. In 3D acquisition systems and integrated CAM-CNC systems, the use of the b-spline in the geometric information

22. SISTEMA DE NAVEGAÇÃO POR GEORREFERENCIAMENTO COM CORREÇÃO DE ROTA POR LÓGICA FUZZY APLICADO À ROBÓTICA AGRÍCOLA"
A agricultura de precisão ainda é um tema considerado novo no Brasil, até mesmo pela Empresa Brasileira de Pesquisa Agropecuária (Embrapa), que em 2012 lançou um livro sobre tema e teve mais de 4500 acessos em menos de um mês de publicação. Isso demonstra que esta é uma área promissora, de interesse geral e pode ser o diferencial para que cada vez

23. Uma plataforma para ensino e treinamento em desenvolvimento de sistemas operacionais / A learning and training platform on operating systems development
This work aims at proposing and developing a learning and training platform on design and implementation of operating systems. After more than a decade of hegemony of a few commercial products, the establishment of free software paradigm and the proliferation of embedded architectures capable of running an operating system (OS) increase the demand for specia

24. Um framework de simulação para verificação de requisitos de desempenho de sistemas computacionais de tempo real
Os métodos tradicionais de validação de requisitos de desempenho de software, baseados em testes do código, permitem a detecção de problemas somente nas fases finais do ciclo de desenvolvimento de software. Mudanças no software nas fases finais do desenvolvimento são em geral mais custosas e demoradas para serem efetivadas do que aquelas identificada
