The potential of the solar energy sector is starting to become increasingly important. The possibility to produce electrical power for household needs, as a result of an investment in photovoltaics is gaining popularity, and storing its surplus in a power grid and settlement of its consumption on the basis of an annual balance, allows to limit electricity bills to the minimum. The implementation stage, which promotes investing in solar renewable energy for own household needs was introduced by the new Act on RES, promoting the prosumer On-Grid system. The paper focuses on presenting the analysis of profitability of installing photovoltaic On-grid systems.

. Dynamic development of social networks caused that the Internet has become the most popular communication medium. A vast majority of the messages are exchanged in text format and very often reflect authors’ emotional states. Detection of the emotions in text is widely used in e-commerce or telemedicine becoming the milestone in the field of human-computer interaction. The paper presents a method of emotion recognition in Polish-language texts based on the keywords detection algorithm with lemmatization. The obtained accuracy is about 60%. The first Polish-language database of keywords expressing emotions has been also developed.

. The article describes concept of an integrated control system for the hybrid electromagnetic launcher. The main issue of the concept control system is to use a real-time controller (CompactRIO-9022) playing additionally role of a measurement system. The control system will be connected to LAN network, which allows to remote control of launcher. In article used controller is described specifically also with available extension and LabView software.

. This paper investigates the characteristics of web server response delay in order to understand and analyze the optimisation techniques of reducing latency. The analysis of the latency behavior for multi-process Apache HTTP server with different thread count and various workloads, was made. It was indicated, that the insufficient number of threads used by the server handling the concurrent requests of clients, is responsible for increasing latency under various loads. The problem can be solved by using a modified web server configuration allowing to reduce the response time.

The article presents the analysis of various kinds of montage applied in the analysis of electroencephalographic data. The present study covers analysis of data obtained as a result of EEG examination of several persons with the age of 23–24 years. Every person has undergone an examination with appliance of 21 electrodes in accordance with classic EEG record method applying the 10–20 system. The examined persons were asked to perform the following activities: sitting steadily with opened eyes, sitting steadily with closed eyes as well as typical cognitive activity i.e. silent reading of given text. Every fragment has been subjected to initial data analysis (filtering, artifact correction) and used for spectral analysis afterwards. The whole analysis has been realized on the basis of four EEG montage examples (two bipolar and two monopolar). For each of them comparative analysis concerning the following points has been carried out: EEG spectra as well as other measures, such as activity maps, diffraction histograms for separate waves and spectrum charts for the selected electrodes.

In this paper testing for revealing data structure based on a hybrid approach has been presented. The hybrid approach used during the testing suggests defining a pre-clustering hypothesis, defining a pre-clustering statistic and assuming the homogeneity of the data under pre-defined hypothesis, applying the same clustering procedure for a data set of interest, and comparing results obtained under the pre-clustering statistic with the results from the data set of interest. The pros and cons of the hybrid approach have been also considered.
