The objective of this research was to reduce water use during the operation of anthracite-sand filters used for treating drinking water. The variables that affect the saturation of the filter bed were evaluated, using ...

In target tracking problems, two of the main concerns are the choice of suitable mathematical models that represent the dynamics of a certain object’s movements and the choice of suitable stochastic filters used to estimate ...

Measurements of plasma velocities in a 30 A high energy density cutting torch are reported. The velocity diagnostic is based on the analysis of the light fluctuations emitted by the arc which are assumed to propagate with ...

This paper describes a novel technique to obtain radar biases estimates that can effectively reduce mismatches in track association algorithms. This is accomplished by matching ship-borne radar images to geo-referenced ...

The present work aims to evaluate, through filtration process and cake detachment, the behavior of two cellulose fiber filtering media with different air permeability values. The powder material used was phosphatic ...

Generally, a road image sequence acquired by a mobile mapping system (MMS) is oriented by integrating the Global Positioning System (GPS) and an inertial navigation system (INS) data. Alternatively, this article presents ...

Kalman filters are rooted in the technical literature, as a way of predicting new states in nonlinear systems providing a recursive solution to the problem of linear optimal filtering. Therefore, 56 years after its ...

Many studies related to bag filters have focused on minimizing the amount of energy used in the process. Seeking longer filtration cycles, lower frequency of cleaning cycles and a longer filter life, such studies search ...

The interest of studies on the development of techniques for removal of particles in the nanosized scale was promoted by concern about air quality and human health, in addition to restrictions on the control of ultrafine ...
