Analyzer system intended to visualize the sound signal in the time and frequency domain is presented. The system was realized in Matlab and it can process sound signals of wav files. Spectral analyzer takes into account the perception of the sound by humans and thus the magnitude spectrum can be visualized with frequency axis in Barks end ERBs. Spectrum can be weighted by the transfer function ...

A fast, quantitative image analysis technique was developed to assess potential rock weathering by bacteria. The technique is based on reduction in the surface area of rock particles and counting the relative increase in the number of small particles in ground rock slurries. This was done by recording changes in ground rock samples with an electronic image analyzing process. The slurries were p...

The rhythmic analyzer and equalizer presented in this paper allows to cut or boost the signal at a given audio frequency and a given rhythmic frequency, that is, number of beats per minute (BPM). A task that can be addressed with the rhythmic equalizer is for instance to emphasize series of 1/8 triplet notes played on the hi-hat of the drum set. The software works in real time and offers an int...

In this paper we make the case of using photographs as a source of data for interpretive research in the information systems field, especially for ethnographic accounts. We treat photographs as knowledge objects and examine the richness of content and context they offer. Based on experiences from anthropology and sociology, we contend that photographs should be used along with other sources of ...

Stereo-vision-based mobile robots observe the i r environments and acquire 3-0 data with considerable errors 1n range. Rather than to use the conventional 2-0 maps, described with these Inaccurate data 1n the absolute coordinate system, a f lex ib le relational model of the global world can be bu i l t with local maps suited for each function of robots such as path planning or manipulation. For...

The concept of a multichannel electron spin detector based on optical imaging principles and Mott scattering (iMott) is presented. A multichannel electron image produced by a standard angle-resolving (photo) electron analyzer or microscope is re-imaged by an electrostatic lens at an accelerating voltage of 40 kV onto the Au target. Quasi-elastic electrons bearing spin asymmetry of the Mott scat...

Computer-assisted sperm morphometry analysis has improved the assessment of sperm morphology, but the results depend on the use of adequate evaluation and staining procedures of spermatozoa from individual species. In this study, the morphological module of the Sperm Class Analyzer® was used for the morphometric analysis of stallion sperm heads and midpieces. Semen samples were obtained from si...

OBJECTIVE A high prevalence of poor standing posture among elementary schoolchildren indicates the need for the introduction of school-based interventions for improvement of postural alignments. For assessing the effect of intervention programs, reliable quantitative measures of standing posture should be used. Therefore, the purpose of this study was to examine the reliability of a photographi...

The main goal of the study was to determine the types of body posture of boys (n = 273), 10 to 13 years of age, by means of the body posture assessment method based on the software Posture Image Analyzer. The results should enable better understanding of postural issues, as well as timely and more precise selection of kinesitherapeutic procedures. Values of 5 front view and 4 sagittal view indi...

Seed analyzer is a mechatronic system for differentiating different types of seeds. It has enormous applications in agriculture industry. Although several seed analyzers are available in the market, still there is large scope for improvement because of their various disadvantages. Most of the analyzers are built using very simple image processing techniques and electronic principles. In this re...
