The glucometer allows the measurement of glycemia to be performed by the user without hindering his daily routine. Two principles are used to measure the level of blood glycemia: photometric and amperometric. On the photometric principle, after biochemical reactions with the sample obtained from capillary venous blood, the glycemia is measured by changing the wavelength of a light beam pattern. On the amperometric principle, after the biochemical reactions with the capillary venous blood sample, intensity of eletric current flowing through the sample can be measured and evaluated, where the intensity of the electric current is proportional to the blood glycemia level. The glucometers available on the market use one of the mentioned principles. Equipment used by biochemical analysis laboratories do make use of the photometric principle with venous blood samples collected from the patient's forearm. This work, approved by the ethics committee, evaluates a set of glycemia measures made by multiple glucometers and laboratory measuring equipment used by clinical laboratories. Presented results demonstrated a strong correlation between glycemia measures obtained from glucometer and equipment used on biochemical analysis laboratories, but with a high rate of systematic and random errors.

The release of untreated sewage is a major factor that helps contributing to water pollution. The sewage treatment, if any, in most cases is insufficient for satisfactory removal of pollutants, primarily for compliance with legal standards. Among the many reasons for this inefficiency, it was highlighted the lack of effective composition of raw sewage input and efficiencies of unit processes at different installation sites, with changes in climate, topography, vegetation, among others. As for other activities, projects of stations and selection of wastewater treatment systems include a laborious and time consuming due to the large number of factors that must be considered. The absence of auxiliary systems for decision making on project related to sewage treatment complicates this process.

Visual novelty detection for autonomous inspection robots

Vieira Neto, Hugo

Tipo: Tese de Doutorado
ENG
Mobile robot applications that involve automated exploration and inspection of environments are often dependant on novelty detection, the ability to differentiate between common and uncommon perceptions. Because novelty can be anything that deviates from the normal context, we argue that in order to implement a novelty filter it is necessary to exploit the robot's sensory data from the ground up, building models of normality rather than abnormality. In this work we use unrestricted colour visual data as perceptual input to on-line incremental learning algorithms. Unlike other sensor modalities, vision can provide a variety of useful information about the environment through massive amounts of data, which often need to be reduced for realtime operation. Here we use mechanisms of visual attention to select candidate image regions to be encoded and fed to higher levels of processing, enabling the localisation of novel features within the input image frame. An extensive series of experiments using visual input, obtained by a real mobile robot interacting with laboratory and medium-scale real world environments, are used to discuss different visual novelty filter configurations. We compare performance and functionality of novelty detection mechanisms based on the Grow-When-Required neural network and incremental Principal Component Analysis. Results are assessed using both qualitative and quantitative methods...
