The study focuses on testing the protection of computing technology and peripheral devices based on radio-frequency identification (RFID) technology in a selected corporate organization. The potential of RFID technology is also employed to obtain statistical data about real-time use of the devices. Based on the comparison of high and ultra high frequency of RFID technology, the appropriate variant was selected for operation, selected devices were tagged with RFID tags, and the success of their detection was monitored both in the test period and in real operation. After three months’ operation, the cost connected with protection implementation...

This paper deals with the prediction of company bankruptcies and defines how this undesirable state can be prevented. Currently, these methods include modern approaches from the area of data mining that can help companies in many ways. In a practical application of data mining methods for predicting the future state of a company, financial indicators of Polish companies were used. In the analyses, we used algorithms suitable for bankruptcy prediction – decision trees that provide a simple interpretation of results. In some experiments, we also used attribute selection methods, LASSO, or the PCA method. The workflow is governed by the CRISP-DM...

The visual impairment of a completely blind person encourages them to develop their abilities in other areas. This concerns mainly a significant improvement in the use of touch, hearing and memory. Blind people can use these skills with the help of assistance technologies when looking for employment. The aim of the article is to show how the presented solution – an ambient system – assists a blind person in their work in the area of electrical engineering and informatics. The article thus contributes to the knowledge base of solution design in the area of active support of visually impaired persons’ employment. This article describes...
