<abstract xmlns="http://www.w3.org/1999/xhtml">The article deals with monitoring the corrosion resistibility of welded materials in the anaerobic fermenter (bioreactor). The main goal of this research is to assess the change of hardness after degradation. The change of hardness occurs in the corrosion environment and it correlates with the corrosion resistibility of material. The purpose of this experiment is to recognize the possibilities of using the CMT welded materials in the defined environment. As an innovative technology the acoustic emission method is used for assessment of surface layer disruption during hardness testing. Aluminium alloy with galvanized steel (AluZinc) was used as an experimental material. The basic materials were welded by the filler material AlSi3.</abstract>

<abstract xmlns="http://www.w3.org/1999/xhtml">The main aim of this article is to present the modern unmanned aerial vehicles (UAVs) and the possibilities for real-time remote monitoring of flight parameters and payload data. In the introduction section of the paper we briefly present the characteristics of the UAVs and which are their major application areas. Later, the main parameters and the various data types for remote control and monitoring of the unmanned aerial vehicles are presented and discussed. The paper continues with the methods and the technologies for transmission of these parameters and then presents a general hardware model for data transmission and a software model of a communication system suitable for UAVs.</abstract>

A Review of the Characteristics of Modern Unmanned Aerial Vehicles

<abstract xmlns="http://www.w3.org/1999/xhtml">The paper focuses on the analysis of compliance with the technological discipline in silage quality assessment based on sampling the silage wall using thermal imaging and penetrometer method for silage compaction. Experimental measurements were done in a selected company, which has built a silage trough with a capacity of 6,624 m3, in which the maize (hybrid KWS – KALIFF FAO 440) with a 36% solids content was ensiled. A thermal camera ThermoPro TM TP8S IR and cone penetrometer Eijkelkamp were used for measurements. The results obtained suggest that also undesirable heating was found in the sampling area, since the maximum temperature at some places in the depth of 0.5 m reached a temperature of 36.4 °C. According to regression and correlation analysis, we found direct linear relationship between penetration resistance and penetration depth in a 6 m and 1.5 m height (<italic>R</italic> = 0.938 respectively <italic>R</italic> = 0.970).</abstract>

Using Modern Diagnostic Methods for Technological Discipline Assessment of Maize Silage

<abstract xmlns="http://www.w3.org/1999/xhtml">The precision and stability of adjusted temperatures are critical requirements for electromechanical thermostats. The key element in meeting the requirement is a thermostat bellows. It is a convertor of pressure into force that actuates the mechanical system of the thermostat. Convolutions enabling the axial movement of the bellows cause that the bellows is partly behaving as a spring. Therefore, the bellows has its own spring rate. The setting of the bellows spring rate influences the critical parameters of the thermostat. The aim of the article is to find the difference between the setting done by bellows producer and setting done by thermostat producer and its influence on the thermostat adjustment.</abstract>

Influence of Bellows Setting on Its Spring Rate and on Temperature Adjustment of Electromechanical Thermostats

<abstract xmlns="http://www.w3.org/1999/xhtml">Mechanical devices in parlours are a source of noise, and this noise has an effect not only on the operators of the parlour but also on dairy cows. They have more sensitive hearing than humans. The aim of this article was to analyse the sound pressure level and determine the noise exposure of dairy cows at different technological solutions of milking parlours, during their day routine. In the experiment, tandem, herringbone and rotary milking parlours were used. Noise exposure was measured during the milking process. After evaluation of noise pressure levels of different types of milking parlours, it can be concluded that in this experiment, the equivalent noise pressure level was lowest in the tandem milking parlour. Equivalent sound pressure levels in the rotary and herringbone milking parlour were almost about the same values. These values are higher than values in the tandem milking parlour, about 10 decibels. The differences within mean <italic>LAFeq</italic> values between the herringbone milking parlour and tandem milking parlour were highly statistically significant (<italic>P</italic> &lt;0.001***).</abstract>

Noise Emissions in Milking Parlours with Various Construction Solutions

<abstract xmlns="http://www.w3.org/1999/xhtml">In order to produce goods of sufficient quality finding buyers in the market, a company must have an adequate knowledge of their production technology. Technologies and finished products at the same time will affect the position of the company in the market and hence its existence in this market. Therefore, it is so important for every company to determine the appropriate technological strategy. The 3 × 3 matrix is a very useful tool to do so. This matrix shows the relation between technological possibilities of the company and its position in the market. However, that requires changing the scale used in the matrix. In practice, this means that both those that have a positive impact on the company and those that have a negative impact on it can be included in the factors. The research was conducted in a food industry company. It turned out that the research company was located in field of the matrix marked as ‚Improve marketing’. It means that the company should put more emphasis on improving the factors related to its position in the market.</abstract>
