Three axis positioning system with conductive contact probe is utilized. The user application was created in MATLAB programming environment. Important part of the design represents the definition of requirements, choice of the appropriate tools, functions and structures needed for reliable realization. Proposed user application allows setting key parameters of the measurement, appropriate method of data acquisition as well as performing online 3D visualization of measured data. The functionality of the application is verified via measurement of a several selected samples. Results of these measurements are also presented.

The question of achieving the audio classification lies in the convenient discrimination of the feature vector in the feature vector space. Characteristics based on frequency analysis were chosen and used as feature vector. Artificial neural network was applied in order to classify different audio classes especially from security and military areas, such as different shots and explosions. The information about specific type of a sound can trigger localization process of given audio source. Moreover, it can improve situation when guards get ready for the alert state. This classification method is currently developed as an additional part of the system for audio source hyperbolic localization; the paper also gives some basic structure of that system. Its utilization can be found for additional securing of larger objects like squares or military basis, for instance.
Effect of Cross-Linking Waste Protein with Dialdehydes on Its Biodegradation Under Anaerobic Conditions

One of the paths to increasing this attribute (if feasible) is their cross-linking, which may, however, affect their readiness to biodegradation. In the presented work this condition was observed on the example of waste protein
