1. ESTIMATION OF PARAMETERS AND STATES USING A BAYESIAN PARTICLE FILTER FOR THE SULFATE ION ADSORPTION PROCESS IN A FIXED BED COLUMN
Abstract Ensuring that industrial effluents meet quality standards to be released into water bodies is still one of the major environmental concerns. Liquid phase adsoption in fixed bed collumns is one of the most known treatments. Measurements are needed to monitor the process. However, as they are often corrupted by noise from the measuring equipment, perf

2. Hydraulic System Onboard Monitoring and Fault Diagnostic in Agricultural Machine
Abstract Agricultural Machinery as an off-road vehicle is the backbone of the World agricultural industry. Its main function is to operate as a prime mover and support the power requirements to function the various type of draft implements. In this regards, the hydraulic system is an important part and is controlled by the propagated oil which is cleaned by

3. Composição granulométrica do filtro ascendente para pós-tratamento de lixiviado de aterro sanitário
RESUMO O lixiviado de aterro sanitário apresenta composição variável e complexa e pode ter elevadas concentrações de nitrogênio amoniacal e matéria orgânica biodegradável e recalcitrante. Devido ao potencial altamente poluidor dos lixiviados estabilizados, além do tratamento biológico convencional, faz-se necessária, em alguns casos, a realizaç

4. Design of Waveguide Structures Using Improved Neural Networks
Abstract In this paper, an improved neural networks (INN) strategy is proposed to design two waveguide filters (Pseudo-elliptic waveguide filter and Broad-band e-plane filters with improved stop-band). INN is trained by an efficient optimization algorithm called teaching–learning-based optimization (TLBO). To validate the effective of this proposed strateg

5. Simultaneous Determination of Furan and Vinyl Acetate in Vapor Phase of Mainstream Cigarette Smoke by GC-MS
ABSTRACT A simple and sensitive method for simultaneous determination of furan and vinyl acetate (VA) in vapor phase of mainstream cigarette smoke with cold trap and gas chromatography-mass spectrometry (GC-MS) was developed. A Cambridge filter pad (CFP) was placed in front of the impingers of smoking machine to remove the particle phase from cigarette smoke

6. Novel Image Classification technique using Particle Filter Framework optimised by Multikernel Sparse Representation
ABSTRACT The robustness and speed of image classification is still a challenging task in satellite image processing. This paper introduces a novel image classification technique that uses the particle filter framework (PFF)-based optimisation technique for satellite image classification. The framework uses a template-matching algorithm, comprising fast march

7. Elemental composition of PM10 and PM2.5 for a savanna (Cerrado) region of southern Amazonia
Brazil plays an important role with regard to the emission of aerosols into the atmosphere. Ecosystems such as the Amazonian tropical forest and Brazilian Cerrado are undergoing sweeping changes. These human activities promote an increase in the levels of gases and particles emitted into the atmosphere. To determine how these activities have affected the emi

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. Reconhecimento de texto e rastreamento de objetos 2D/3D / Text recognition and 2D/3D object tracking
In this thesis we address three computer vision problems: (1) the detection and recognition of flat text objects in images of real scenes; (2) the tracking of such text objects in a digital video; and (3) the tracking an arbitrary three-dimensional rigid object with known markings in a digital video. For each problem we developed innovative algorithms, which

10. PROTETORES SOLARES À BASE DE FILTROS INORGÂNICOS: DESENVOLVIMENTO E CARACTERIZAÇÃO
The inorganic sunscreens represented mainly by titanium dioxide (TiO2) and Zinc Oxide (ZnO), were classified as inert particles, therefore, they are pointed out as the best way to protect the skin against the harmful effects of ultraviolet radiation (UV). However, recent studies suggest that these particles have several stability problems that may lead to a

11. Study of various numerical aspects of 3D-SPH for simulation of the dam break problem
Recently, the Smoothed Particle Hydrodynamics (SPH) method has been utilized as an effective tool for capturing details of the fluid flows. The Lagrangian nature of the SPH method facilitates the modeling of the free surface flows. In the present article, different numerical features of 3D-SPH are probed to find a set of options that can be used to achieve a

12. Optimal design of double folded stub microstrip filter by neural network modelling and particle swarm optimization
Optimization of design parameters based on electromagnetic simulation of microwave circuits is a timeconsuming and iterative procedure. To provide a fast and accurate frequency response for a given case study, this paper employs a neural network modelling approach. First, one of the case study's outputs, i.e., scattering parameter (|S21|) in dB, is predicted
