Introduction. Football training should be organized in view of the requirements of contemporary sports and should be analyzed based on data obtained by observing the best teams in action. The goal of this study was to compare the frequency and effectiveness of selected tactical and technical actions performed by footballers from winning and losing teams in selected matches from the Euro 2008. Material and methods. The study involved close observation of performances by 166 players from 11 countries in 8 matches (Turkey-Czech Republic 3:2; Turkey-Switzerland 2:1; Italy- France 2:0; Holland-France 4:1; Sweden-Greece 2:0; Spain-Sweden 2:1; Germany-Portugal 3:2; Spain-Germany 1:0). The total amount of game observation time equaled 720 minutes. Analysis was conducted by repeatedly viewing DVDs of matches and coding the results on a detailed observational spreadsheet containing a detailed breakdown of offensive actions such as attempting goals, passing the ball or 1v1 attacking. Results and conclusions. Analysis showed that winning teams were more effective in seven out of eight indexes, i.e.: overall effectiveness in offense, effectiveness in attempting goals, overall effectiveness in passing, effectiveness in passing in easy situations, and effectiveness in 1v1 attacking. Losing teams were more effective solely in the index for passing in difficult situations.


Users of machines and engineering devices force continuous improvement of their functionality and efficiency while reducing energy consumption. For this purpose, numerous sensors are installed in the machines in both drive systems and execution systems. Sensors are a source of information for control units and also allow reading parameters during diagnostic tests. The diagnostician should have the appropriate interface and knowledge of the operating principles of the tested machine. In order to facilitate the implementation of the diagnostic process even by less experienced service personnel, it is proposed to use a diagnostic interface based on the application developed in the Android system, which main element is a QR code scanner. The system uses MATLAB-Simulink, database and PHP script to work properly. This system allows performing a diagnostic test and identifying potential causes of device failure. The system has friendly interface where is implemented many useful things like graphs and visualization of device movement. The application reads the nominal operating parameters stored in the QR code of the machine and displays the next steps necessary to assess the technical condition of the object. On the basis of a comparison of registered and nominal machine parameters, the application indicates possible fault locations. The implementation of the database on an external server allows the application to run anywhere on android devices that have access to the internet. Through the registration process, it is possible to create a database of employees who have access to the system. The diagnostic system for storing all information, such as employee data or current sensor measurement values uses the MySQL database. Preliminary tests of the application carried out during diagnostics of the hydraulic and mechanical system of the building manipulator confirmed the functionality of the developed system.
