    New equipment was designed and developed to evaluate the physical characteristics of animal fibres, based on an automatic digital analysis system (ADAS) that allows the capture of a series of real-time images. In the development of the mechanical component, a design tool was used that allows visualization, simulation, and documentation of the product.

    Robust range finder through a laser pointer and a webcam

    Currently, there is a great interest in the study of three-dimensional reconstruction from digital images. The applications of photogrammetric algorithms has allowed us significant improvements in procedures of camera calibration, movement of objects in scenes, shape from shading and range images. The procedure of the distance estimation from simple images is important to find the depth measurements in any procedure of three-dimensional reconstruction of scenes. In this work, we describe an adaptation of a scanner prototype based on a laser pointer and a webcam.

    Pneumonia is one of the major causes of child mortality, yet with a timely diagnosis, it is usually curable with antibiotic therapy. In many developing regions, diagnosing pneumonia remains a challenge, due to shortages of medical resources. Lung ultrasound has proved to be a useful tool to detect lung consolidation as evidence of pneumonia. However, diagnosis of pneumonia by ultrasound has limitations: it is operator-dependent, and it needs to be carried out and interpreted by trained personnel. Pattern recognition and image analysis is a potential tool to enable automatic diagnosis of pneumonia consolidation without requiring an expert analyst. This paper presents a method for automatic classification of pneumonia using ultrasound imaging of the lungs and pattern recognition.

    Optimization Criteria in Mössbauer Spectroscopy

    The application of optimization criteria both in sample preparation and instrument configuration is very important in Mössbauer spectroscopy in order to compensate for the long periods of time required for the accumulation of spectra with an adequate statistical resolution. The criterion of optimum sample thickness is rather well known in the Mössbauer community. In this work we emphasize the criteria for optimum saturation level due to dead time and optimum window configuration in the gamma detection system.

    High-temperature in situ Mössbauer spectroscopy was used to investigate the nanocrystallization process in Fe73.5Si13.5B9Cu1Nb1X2 (X=Zr, Nb, Mo and V) amorphous alloys. The Mössbauer spectra were taken at temperatures where only the amorphous phase is found in a paramagnetic state, allowing an accurate resolution between the amorphous and crystalline phases presented in the annealed ribbons.
