The paper deals with a determination of robust stability regions in a plane of conventional analog controller adjustable parameters for common controlled plants with time delay. There are derived rather general formulas, which allow to render both stability regions and regions for specified gain or phase margin. Knowledge of these regions allows to verify a robustness of different controller tuning methods for plants with uncertainties. For the most common plants with time delay of the first and the second order with time delay user-friendly formulas are given. The use of a described approach is shown in the example.

This paper deals with the theoretical basis for measurement of small accelerations using the miniature capacitive feedback sensor. The sensor itself is non-linear an unstable system. The aim of the paper is to design both stabilizing and feedback control systems to enable measurement of small accelerations. We propose the conversion of acceleration to an appropriate electrical quantity, feedback stabiliser and compensator. Analysis of the precision with its relationship to the controller is also analysed.

The main objective of the proposed project was to improve quality of teaching for graduates and specialists in technical study programs (Applied Mechatronics and Automotive Mechatronics) and related areas of automation using latest ICT technologies, virtual reality and interactive learning in modelling, simulation and control. Visualization of the modelling and control processes of complex mechatronic systems, components and devices (e.g cars, electric vehicles, mechatronic systems in consumer electronics, health care, etc.) in virtual and mixed realities will give students more insight and better understand the studied stuff compared with conventional learning methods.

This paper provides a cloud-based architecture for the healthcare data classification, which is the part of a broader concept called Healthcare Industrial Internet of Things (HealthIIoT). HealthIIoT is a concept incorporating communication technologies, Things (devices, sensors and actuators), interconnected applications, and people that emerges new possibilities in data management. The cooperation among Operational Technology (OT), Information Technology (IT) and people allows to create one smart system to monitor, track, and store patients' healthcare information for ongoing care. Therefore, we provide our case study in which we took hospital data and used cloud services for data storing and machine learning. Then we have developed a web application on the top of this architecture and evaluated the concept in the real environment of the hospital.

The paper deals with problem of trajectories optimization of mobile robotic systems using discrete Kalman filtration (DKF). Localization and optimization of the trajectory were performed in indoor spaces using the infrared camera StarGazer. The used Mecanum omnidirectional chassis allows great maneuverability, but the movement itself causes deflection from the desired trajectory. The minimization of these deflections was solved by generally standard procedures and then we compared them with the outputs obtained with DKF. The results were quantified and evaluated at the end of the article.

The purpose of this study is to identify DC Motor, 12 V with 1:19 ratio. Mathematical model in MatLab has been created using datasheet for purpose of control design. We design controller in MatLab and implement it on FPGA. FPGA is digital system therefore an analogue to digital conversion is needed to be done for PI controller as well as adjustment for FPGA output. This is done via PWM.

This paper studies a real-time face detection problem for online web applications and its solution. The main aim of this paper is describe functionality of effective face detection algorithm and analyze existing solution in order to improve current situation. To obtain satisfying results Viola-Jones object detection framework is chosen, which uses feature selection in combination with Integral images, AdaBoost training and Cascading classifiers. This algorithm is highly popular among existing javaScript frameworks for face or another objects detection for its extreme speed of image processing while achieving high detection rates and multiple objects detection. As analyzed answer for solving stated problem a javaScript tracking.js is chosen.

The paper considers two kinds of optimization methods: constraint programming and metaheuristic search. It shows how each of the approaches can be applied to multiple instances of the job shop scheduling problem and compares the performance of these approaches among themselves and also under various parameter settings. It is shown that, given the instances of the problem and the parameter configurations considered in the paper, constraint programming clearly outperforms the other approaches. In its final section, the paper outlines further conclusions as well as suggestions for future work.
