The article concerns the experiences of students related to hybrid education conducted in the first semester of the academic year 2021/2022. The aim of the study was to find out the opinions of students on hybrid education conducted at The Maria Grzegorzewska University and to compare it with traditional education and distance education. The subject of the research was, among others, the readiness of students to participate in hybrid learning, assessing its quality and other related experiences. The research used the method of diagnostic survey. The obtained results indicate that students rate their readiness to participate in hybrid education higher than the readiness of lecturers to conduct it. They see the possibility of using a hybrid approach to education and science, organization of education and health. They indicate convenience, organization and health safety as the most important advantages and social costs, student attitudes and technical problems as the most important disadvantages of hybridization. The article also presents the expectations of students in relation to the systemic sanctioning of hybrid education. It was suggested to use the lessons learned by developing and testing the effectiveness of a hybrid approach, the potential of which is undeniable and scientifically proven.

Dynamic angle measurement (DAM) plays an important role in precision machining, aerospace, military and artificial intelligence. Because of its advantages including high sensitivity, solid state and miniaturization, fibre-optic gyroscope (FOG) has great application prospects in the field of DAM. In this paper, we propose a dynamic angle metrology method based on FOG and a rotary table to evaluate the DAMaccuracy with FOG. The system synchronously collects data from the FOG and rotary table, and analyses the DAM accuracy of the FOG for different sway conditions compared with that of the angle obtained from the rotary table. An angle encoder in the rotary table provides absolute or incremental angular displacement output with angular displacement measurement accuracy of 10′′ (0:0028◦) and angular displacement repeat positioning accuracy of 3′′ (0:00083◦), and can be used as an angle reference. The experimental results show that the DAM accuracy of the FOG is better than 0:0028◦ obtained with the angular encoder, and the absolute DAM accuracy of the FOG is better than 0:0048◦ for given conditions. At the same time, for the multi-path signal synchronization problem in the metrology field, this paper proposes a signal delay measurement method combining test and algorithm procedures, which can control a delay within 25 μs.

In this paper the way of modeling phenomena occurring during the voltage and current waves passing through a point connection of two lines, with different wave impedance operators, is presented. This connection point is called „the wave transformer”. The analyzes and the resulting formulas concern not the frequency domain, but the time domain. The appropriate transition matrices of waves through the wave transformer are defined. This matrices are the convolution integral-derivative operators of fractional order (the digital filters). For a lossless line the wave transition matrices through the wave transformer become number type instead of operator type. All matrix multiplications occurring in the formulas should be understood in convolution way.

This article presents a profi le of Stanisław Jaworski as a literary scholar with a life-long involvement in avant-garde literature. He defi nes the avant-garde as a mosaic of diverse trends with no common aesthetic or ideological denominator and, at the same time, as a transcultural network of artists apparently unrelated artists. Focusing on his major studies (Foundations of the Avant-garde, Tadeusz Peiper: Writer and Theoretician, Between the Avant-garde and Surrealism, and The Avant-garde) the article reconstructs Jaworski’s insights and theoretical constructs in the context of contemporary network studies and reassesses his commitment to both history and theory of literature.
