An innovative issue in food engineering is using the impulse electric field (PEF) in modeling the content of biologically active compounds in plant raw materials, including seeds. In the described experiment it was shown that it is possible to modify the carotenoid content in germinating seeds of red clover (Trifolium pratense L.) by treating the seeds with PEF before cultivation. The research material was the seeds of red clover 'Rozeta' variety. As a result of the conducted research, an increase in the content of lutein and zaaxanthin by 10% and β-carotene by 16% was obtained after the sprouts were subjected to a field of 5 kV/cm intensity.

The paper provides a rationale for the use of low-power wireless communication to create non-invasive bionic limb prostheses. The need for such a connection is dictated, on the one hand, by the expediency of using sensors located in various parts of the body, often very remote from each other, on the other hand, by the desire to free the disabled person's body from the wires that would envelop it like a spider web. For each of these positions, arguments are given.
Despite the development of medicine, as well as robotics aimed at helping people with disabilities, most disabled people with missing limbs cannot hope for a full life with the help of bionic prostheses, since these p...
Despite the development of medicine, as well as robotics aimed at helping people with disabilities, most disabled people with missing limbs cannot hope for a full life with the help of bionic prostheses, since these products are made strictly individually, and their control requires expensive surgeries to implant sensors. In addition, such prostheses themselves are very expensive. An alternative solution is to reduce the cost of such prostheses as much as possible and abandon the implantable sensors of signals of the human nervous system. The paper proposes a method for solving such a problem using a variety of sensors that remove signals from the skin surface without invasive surgery.
Consciousness has been historically a heavily debated topic in engineering, science, and philosophy. On the contrary, awareness had less success in raising the interest of scholars in the past. However, things are cha...

Lyapunov functions are a widely used tool to evaluate stability properties of nonlinear dynamical systems' equilibria. In this paper quantifier elimination is used to construct Lyapunov functions for polynomial systems from a parametric ansatz. Because the existing algorithms for quantifier elimination are inherently computationally expensive, a strategy is to simplify the quantifier elimination problem beforehand. A method is presented that may help simplifying the problem of finding suitable Lyapunov functions by deriving easier to evaluate necessary conditions. Finally, the introduced method is applied to an example system to show local asymptotic stability of an equilibrium point by constructing a Lyapunov function.

In this article a multimedia computer-assisted learning (MCAL) system is presented. The major objective of this work was to investigate the potential of using such systems as tools for transferring instructional course information through various types of computer media as opposed to the classic CAL systems. The philosophy and techniques employed to design the system are investigated. Usage of the implemented system and its merits have been illustrated through its application to teach engineering students and technicians the theory and concepts of marine radar. System design, implementation, test, and revision phases are presented and discussed.

Artificial Intelligence (AI) is a very promising field of development, in many directions. It is widespread in computer technology (biotechnology, nanotechnology, Internet of Things, etc.) as well as in robotics, 3D printing, quantum computing, and many more. Using it to predict and defend from cyber attacks is another of its many applications. In conduct of a project to study the security of cyber-physical connections in the context of next-generation computer networks, an overview of AI methods and their application in Industry 4.0 has been made. More attention has been given to the application of AI as a mean of protecting technologies such as SCADA, industrial Internet of Things, and in general cyber- physical connections. The aim of this study is to present and compare different methods of AI for fighting cyber attacks, or rather their application in systems for detecting and preventing intrusions in the field of the technology mentioned.
