This paper considers the implementation of distributed video coding based on hierarchical wavelet transform. The low - frequency coefficients of the eighth and ninth decomposition levels are transmitted as key frames. Every second frame is skipped and interpolated in the decoder by key frames and additional (side) information containing wavelet coefficient prediction errors and considered as motion vectors. A comparison of the developed software complex and the DISCOVER codec was made based on the dependence of the signal-to-noise ratio on the bitrate. The concept of movement complexity is introduced and the gain from the application of the developed algorithm for generating side information using the BD-PSNR criterion is estimated for different video sequences.

The purpose of this paper is to present an implementation of a cluster of 20 Raspberry Pis and different local multi-node deployments of Kubernetes on top of it. The presented approaches differ both in terms of the used lightweight Kubernetes solutions and the used operating systems. Besides the different methods for deploying applications in containers, in the current paper are presented the interactions with the cluster as well as their differences. Based on collected metrics from the Kubernetes nodes are presented and compared loads of the different deployments.

This paper presents comprehensive research on the influence of the parameters and characteristics of wearable antennas on off-body channels in Wireless Body Area Networks (WBANs) in an indoor environment at 2.41 GHz in a line-of-side scenario. From the results, we can conclude that the surface, radiation efficiency, and radiation pattern of the wearable antenna play a vital role in the definition of the off-body channel characteristics.

The article discusses some aspects of teaching mechatronic systems based on a physical model of an elevator. After introducing the major building blocks of a typical mechatronic system, state-of-the-art control approaches are discussed in the paper. They include the software-centric jump table, the hardware-oriented finite state machines, and the use of the modern meta-operating system for robots ROS. The described physical laboratory mock-up and the suggested control methods provide a solid platform for teaching mechatronics in a real or remote environment without loss of realism.

Working in the mining industry is associated with a serious risk to the health of workers. For this reason, increasing the level of automation and security is a topical issue. The article proposes a project for the construction of a system for monitoring the atmosphere in an open pit mine using wireless technologies. The considered platform offers a universal, flexible and affordable device, allowing the collection and analysis of a large amount of data in real time. Experiments have been conducted with sensors of microelectromechanical type, which appear to be a good candidate to replace the more expensive electrochemical ones.

This paper11This publication has emanated from research conducted with the financial support of the Bulgarian National Science Fund (BNSF) under the Grant No. KP-06-IP-CHINA/I (K∏-06- HIT - KHT AN/1). describes a generic architecture for the creation of universal interpersonal communication applications (UICAs) capable of selecting the ‘best’ service for communication with particular person(s), depending on the current context, based on the calculated service ratings considering different evaluation criteria. A suitable service categorization, serving the UICAs, is proposed. The relevance of the UICA approach to a user-centric realization of the Always Best Connected and best Served (ABC&S) communication paradigm is highlighted.

The various software availability for deep neural network implementation enables students easy and accessible implementation of different tasks in a wide area range. The ready for use applications using, for many of the deep neural network training stages is not related to a deeper understanding of the deep neural network theory. For this reason, the authors of this paper have developed an exercise with students' participation as many of the stages of the deep neural network training as possible. This paper presents one solution for laboratory exercise process organization in distance learning in deep neural network area. Each stage of the student's work is examined in detail. The specifics of its distance learning implementation are also discussed.
