Many emerging organic semiconductor devices suffer from hysteresis effects caused by traps. The impact of such traps on AC device performance has not been investigated yet. In this paper, high-frequency non-quasi-static effects related to dynamic trapping based on a theoretical framework, TCAD simulations and experimental data have been studied. In contrast to previous studies, the focus of this paper is the OFET's high-frequency performance and not the characterization of the traps.

Authors presents a very important problem of estimation capacitance structures used in MEMS sensors. The importance comes from the fact that during operation, inertial sensors deform under influence of external forces. The result of the problem is visible in capacitance deviations what directly may be seen in accuracy sensor measurement.

In this paper, concepts of fractional-order (FO) derivatives are discussed from the point of view of applications in the circuit theory. The properties of FO derivatives required for the circuit-level modelling are formulated. Potential problems related to the generalization of transmission line equations with the use of FO derivatives are presented. It is demonstrated that some of formulations of the FO derivatives have limited applicability in the circuit theory. That is, the Riemann-Liouville and Caputo derivatives with finite base point have a limited applicability whereas the Grünwald-Letnikov and Marchaud derivatives lead to reasonable results of the circuit-level modelling.

In this paper, the simulation method of signal propagation along fractional-order (FO) transmission lines is presented. Initially, fractional calculus and the model of FO transmission line are introduced. Then, the algorithm allowing for simulation of the nonmonochromatic wave propagation along FO transmission lines is presented. It employs computations in the frequency domain, i.e., an analytical excitation is transformed to the frequency domain, multiplications with phase factors are executed, and finally the result is transformed back to the time domain. This algorithm involves elementary functions only and the fast Fourier transformation, hence, computations are numerically efficient and accurate. However, applicability of the method is limited by the sampling theorem. Numerical results are presented allowing for the evaluation of the method.

The paper presents the Linux kernel driver for analog-to-digital and digital-to-analog converters control. The proposed module is the main part of the distributed embedded system for impedance measuring applications. The designed prototype consists of three hardware components: Raspberry Pi 3, microcontroller and personal computer. Two experiments verified the functionality and parameters of the constructed system. The first one confirmed that the driver does not utilize processor time while the data processing application is not running. It also showed that the module consumes only 0.7 % and 3.3 % of two cores of a quad-core processor for data readout and its copying to the user space. The mentioned test was performed with the sampling frequency equal to 256 kHz. The second experiment determined the accuracy of impedance measurements done by the constructed prototype. Results were compared with ones realized with the commercially available measuring device usage. The determined measurements uncertainty did not exceed 1.5 %.

Autonomous mobile vehicles need advanced systems to determine their exact position in a certain coordinate system. For this purpose, the GPS and the vision system are the most often used. These systems have some disadvantages, and so the GPS signal is unavailable in rooms and may be inaccurate, while the vision system is strongly dependent on the intensity of the recorded light. This work presents a system for determining the position of the robot base on information about the distance travelled coming from each vehicle wheel and the IMU sensor. However, wheels odometry introduces an additive measurement error (rise in every measure cycle). In this work there has been a vision correction system applied, where corrections are calculated by measuring the distance to artificial markers. This system precisely determines such correction. Each of these systems is described in the paper, in particular the vision system. There is also a description of a fusion algorithm of wheels odometry and vision correction system. The presented system was tested on an artificially built test track.
