1. Estudo da influência da adição de etanol e/ou metanol ao biodiesel associado a ferramentas quimiométricas
The objective of this work is to study the influence of the addition of alcohol methanol or ethanol - to biodiesel. Therefore, Principal Components Analysis (PCA) was combined with infrared spectra with the aim of separating soybean and tallow biodiesel samples with different alcohol contents of ethanol or methanol. PCA yielded a good reduction of data regar

2. Quantum block codes with unequal error protection / CÃdigos de bloco quÃnticos com proteÃÃo desigual de erros
Quantum error correction codes have been developed to enhance the reliability of the quantum hardware. The majority of the known quantum codes belong to the class of block codes, while quantum convolutional codes have been recently proposed. The class of unequal error protection (UEP) codes, well known in the theory of classical codes, has not been studied i

3. SeleÃÃo de protÃtipos: combinando auto-geraÃÃo de protÃtipos e mistura de gaussianas
Prototype selection is a machine learning scheme in which the main purpose is to choose pattern vectors from the training dataset that achieve a better fit to data point distributions and maintain class separation. The aim of this kind of technique is to find the smallest possible prototype set that minimizes the classification error rate. Prototype-based st

4. Development of an automated and dedicated measuring system for straightness evaluation
This work presents an automated and dedicated system aiming at the measurement of straightness errors of mechanical components, using an industrial robot. A multi-probe error separation technique was used to make measurements independent from the coordinate system of the robot. A mathematical model that takes into account the readings from three sensors was

5. A semi-parametric methodology to IBNR (Incurred But Not Reported) / Uma metodologia semi-parametrica para IBNR (Incurred But Not Reported)
We compare several forecast techniques for IBNR(Incurred But Not Reported) from a Run-Off triangle data, since the most simple techniques like Chain-Ladder and Separation Technique, to the more complex using Log-Normal models and Compound Poisson distribution. Therefore, exist the necessity of the use of Nonparametric techniques, using a model that consider

6. Flatness measurement system / Sistema para medição de erro de planicidade
A acuracidade dos processos de medição e de montagem que utilizam os desempenos como referência depende principalmente da planicidade dessas superfícies. Se a referência está fora das especificações é inútil utilizar instrumentos sofisticados e de alta acuracidade. Neste trabalho é apresentado um sistema para medição de desvios de planicidade de

7. Physical Characterization and Quantification of Bacteria by Sedimentation Field-Flow Fractionation
Studies in microbial ecology require accurate measures of cell number and biomass. Although epifluorescence microscopy is an accepted and dependable method for determining cell numbers, current methods of converting biovolume to biomass are error prone, tedious, and labor-intensive. This paper describes a technique with sedimentation field-flow fractionation

8. Technique for Simultaneous Determination of [35S]Sulfide and [14C]Carbon Dioxide in Anaerobic Aqueous Samples †
A technique for the simultaneous determination of [35S]sulfide and [14C]carbon dioxide produced in anaerobic aqueous samples dual-labeled with [35S]sulfate and a 14C-organic substrate is described. The method involves the passive distillation of sulfide and carbon dioxide from an acidified water sample and their subsequent separation by selective chemical ab

9. Human smooth and saccadic eye movements during voluntary pursuit of different target motions on different backgrounds.
Horizontal and vertical eye movements of ten human subjects were recorded with a scleral induction-coil technique during voluntary pursuit of sinusoidal, triangular and pseudo-random target motions of different frequency, amplitude and dimensionality upon a dark, diffuse or structured background. Data processing included separation of the composite eye movem
