Konferenční objektpeer-reviewedpostprint Otevřený přístup Counting Livestock with Image Segmentation Neural Network(Springer Nature Switzerland AG, 2020) Doležel, Petr; Štursa, Dominik; Honc, Daniel; Merta, Jan; Rozsívalová, Veronika; Beran, Ladislav; Hora, IvoLivestock farming industries, as well as almost any industry, want more and more data about the operation of their business and activities in order to make the right decisions. However, especially when considering very large animal farms, the precise and up-to-date information about the position and numbers of the animals is rather difficult to obtain. In this contribution, a novel engineering approach to livestock positioning and counting, based on image processing, is proposed. The approach is composed of two parts. Namely, a fully convolutional neural network for input image transformation, and a locator for animal positioning. The transformation process is designed in order to transform the original RGB image into a gray-scale image, where animal positions are highlighted as gradient circles. The locator then detects the positions of the circles in order to provide the positions of animals. The presented approach provides a precision rate of 0.9842 and a recall rate of 0.9911 with the testing set, which is, in combination with a rather suitable computational complexity, a good premise for the future implementation under real conditions.Konferenční objektpeer-reviewedpostprint Otevřený přístup Static compensator for nonsquare systems – application example(Springer Nature Switzerland AG, 2020) Honc, Daniel; Dušek, František; Merta, JanThe paper deals with the decentralized control of multivariable systems with the number of manipulated variables greater than the number of controlled variables. Proposed static compensator ensures automatic creation of input/output pairs for the simple control loops. The compensator provides steady-state autonomy and unit gain of the controlled system. Steady-state gain matrix and vector of the off-sets are enough information for the compensator design. Laboratory example is presented to demonstrate innovative compensator design and its application.Konferenční objektpeer-reviewedpostprint Otevřený přístup Smart, Precision or Digital Agriculture and Farming - Current State of Technology(Springer Nature Switzerland AG, 2020) Honc, Daniel; Merta, JanTogether with smart homes, cities and factories, energy hubs and self-driving cars the smart agriculture or farming could be a way how to increase yields and efficiency as well as improve the welfare of farm animals, grow high quality crops and preserve the natural resources. Smart, precision and digital agriculture and farming current state survey with the technical challenges, interesting applications and future prospects is the aim of the paper. Worldwide and UE view is presented and compared with the situation in the Czech Republic. Authors are seeking for used or at least potential agriculture and farming applications of soft computing methods like fuzzy logic, machine learning and evolutionary computa-tion.Konferenční objektpeer-reviewedpostprint Omezený přístup Thermal Process Control Using Neural Model and Genetic Algorithm(Springer Nature Switzerland AG, 2019) Honc, Daniel; Doležel, Petr; Merta, JanPredictive Controller of a laboratory thermal process is presented in the paper. Process model is approximated by a neural network. On-line optimization is done by a genetic algorithm. Control algorithm is tested on the laboratory thermal process and compared to the standard control methods like predictive controller with the transfer and state-space linear model and the quadratic programming optimization method or a PI controller.Konferenční objektpeer-reviewedpostprint Omezený přístup Static Compensator for Decentralized Control of Nonsquare Systems(Springer Nature Switzerland AG, 2019) Dušek, František; Honc, Daniel; Merta, JanThe paper deals with the decentralized control problem for linear multivariable systems with the number of manipulated variables equal or greater than the number of controlled variables. Proposed static compensator ensures automatic creation of input/output pairs for individual control loops. The compensator provides steady state autonomy and unit gain for the control loops. Steady state gain matrix of the controlled system and vector of offsets are sufficient infor-mation for the compensator design. Estimation of the gain matrix and offsets from the measured data is also proposed in the paper.Konferenční objektpeer-reviewedpostprint Otevřený přístup Software for Thermogravimeter(IEEE (Institute of Electrical and Electronics Engineers), 2019) Dušek, František; Honc, Daniel; Havlíček, Libor; Merta, JanSoftware for thermogravimeter constructed at the Department of Inorganic Technology, University of Pardubice is presented in the paper. Used hardware and design of the experiment is described briefly. Main part of the paper focusses to the software solution in MATLAB environment. Except control, plotting and data exporting tasks it was necessary to communicate with Eurotherm nanodac Recorder / Controller through the TCP/IP Modbus protocol and with Sartorius weigh cell through the serial USB ASCII-based protocol. Simple example of Constant Rate Thermal Analysis experiment is given at the end of the paper.
