25. Desenvolvimento de um algoritmo para identificação e correção de spikes em espectroscopia Raman de imagem
Raman imaging spectroscopy is a highly useful analytical tool that provides spatial and spectral information on a sample. However, CCD detectors used in dispersive instruments present the drawback of being sensitive to cosmic rays, giving rise to spikes in Raman spectra. Spikes influence variance structures and must be removed prior to the use of multivariat

26. Estudo da interação de nanotubos de carbono com substrato de quartzo cristalino
Single wall carbon nanotubes (SWNTs) are quasi-onedimensional structures consisting of a rolled up graphene nanoribbon. Due to their unusually large surface-to-volume ratio, SWNTs are strongly affected by the environment. Contact with a supporting substrate modifies their properties, and such interactions have been broadly studied as either a drawback or a s

27. Drawback suspensão integrado: implantação e redução de custos nas importações de matéria-prima de empresa exportadora
A crise econômica mundial que teve o seu auge no final do segundo semestre de 2008, mostrou-nos o quanto a busca por reduções e controle dos custos são fundamentais também em momentos de crescimento econômico intenso, para manter a competitividade e em muitos casos, a sobrevivência da empresa perante aos concorrentes locais e globais durante e após o

28. Inovação e desempenho exportador de empresas catarinenses: uma perspectiva institucional
O presente estudo foi conduzido com o objetivo de avaliar o impacto dos fatores institucionais e da inovação sobre o desempenho exportador das empresas, a partir do caso catarinense. Utilizando como referencial básico o conceito de North (1990) de que as instituições são as regras do jogo e, portanto, afetam os comportamentos dos indivíduos, entende-s

29. A DOE based approach for the design of RBF artificial neural networks applied to prediction of surface roughness in AISI 52100 hardened steel turning
The use of artificial neural networks for prediction in hard turning has received considerable attention in literature. An often quoted drawback of ANNs is the lack of a systematic way for the design of high performance networks. This study presents a DOE based approach for the design of ANNs of Radial Basis Function (RBF) architecture applied to surface rou

31. Cement composites reinforced by short curaua fibers
The development of an eco-friendly material that could reduce CO² emission and that could aggregate value to a natural fiber, setting man at the countryside and raising the income of populations from poor regions is a challenge. Lignocellulosic fibers are cheap and are a readily available reinforcement, requiring only a low degree of industrialization for t

32. Hardware/Software codesign of particle filter for real time localization of mobile robots / Co-projeto de hardware/software do filtro de partículas para localização em tempo real de robôs móveis
Sophisticated techniques for estimation of models based on simulation, particle filters or Sequential Monte Carlo Methods, were recently used to solve many difficult problems in the field of mobile robotics. However, the success of particle filters was limited to the computation of parameters in low dimensionality spaces. The current research efforts in mobi

33. Estimation of underreporting of live births by the capture-recapture / Estimação de sub-registro de nascidos vivos pelo método de captura e recaptura
Introduction Capture-recapture method has been used in Epidemiology since the middle of twentieth century and from the 1990s on, huge number of publications about applying and developing the method on this area have been noted. Underreporting of vital events is still a drawback for the direct calculation of health indicators like fertility and infant mortali

34. Algoritmos evolucionÃrios multipopulaÃÃo na otimizaÃÃo multiobjetiva da remediaÃÃo de Ãguas subterrÃneas / Multi-population Evolutionary Algorithm Multi-Objective Optimization of Groundwater Remediation
Through the last three decades the evolutionary algorithms have been successful on application to many areas. Easily applied, efficiency and confidence are the main advantages of the evolutionary algorithms. In the groundwater remediation, generally, the objectives are the cost minimization, minimization of contaminant presence, maximization of pumping effic

35. Avaliação da destreza manual em pessoas com síndrome de Down
Children with Down syndrome (DS) show slower development when compared to normal population of same age, and also reveal handicap in oral expression, cognition and psychomotricity. The quantitative assessment of the motor performance on upper limbs in children with DS is important to design strategies of early stimulation and adequate therapeutic approaches

36. Materiais e técnicas contemporâneas para controle de ruído aéreo em edifícios de escritórios: subsídios para especificações / Contemporaneous materials and techniques to air noise control on corporate edifices: specification foundations
Big cities have been taken the ground thought freeways and avenues, where constant and loud noise takes place. At theses ways, corporate edifices are also often established, so they naturally become exposed to the external noise interference, regardless the own internal facilities noising. The consequence is that people how work at these places are more pron
