Logistics is primarily to address issues with whose functional, organizational, personnel and material means can be improved and optimize the entire course material flow businesses, which shall logistics integration business functions. Production logistics means a sum of logistical tasks and measures for preparation and execution of the production process. Includes all activities associated with material and information flows of raw materials, auxiliary and production materials from the warehouse to the production of raw materials and semi-finished goods from the warehouse and purchased parts through the various steps of the manufacturing process including all buffer stores, through the installation of the finished goods warehouse. © (2014) Trans Tech Publications, Switzerland.

With growing interest in laboratory automation and high-throughput systems, the amount of generated experimental data is rapidly increasing while analysis methods still require many manual work hours from experts. This is prevalent in X-ray photoelectron spectroscopy (XPS), where quantification is a complex, time-consuming, and error-prone task. We therefore propose a neural network-based workflow to make this process more approachable. As training data availability ranges from insufficient to non-existent, our workflow creates a synthetic dataset containing XPS signals and corresponding area percentages based on binding energies supplied by the user. As a result, no previous measurements are needed. After training on the synthetic data, the neural network can predict area percentages of the known binding energies with high confidence. This workflow can therefore be adapted for XPS quantification tasks to filter significant data and supervise processes. Moreover, this enables non-experts to analyze spectra and can help experts to reduce focus on important spectra. © 2024 by Walter de Gruyter Berlin/Boston.

A basic control course is taught for electrical engineering students at the University of Debrecen, Hungary. Through two semesters the students get a basic knowledge on control concepts. Every week there are 2 hours of theoretical lectures immediately followed by 2 hours of MATLAB based interactive computer laboratories. In the curriculum besides the conventional material new aspects of control design such as Youla parametrization have also been included. Practical considerations as e.g. controller saturation are also dealt with. The paper reviews briefly the curriculum and the educational process of this program. © IFAC.

Differential flatness has been defined in the literature for continuous time dynamical systems and for discrete time systems. We define flatness of automata from the perspective of behavioral systems theory, and synthesize a flatness definition for hybrid automata. These new definitions allow for feedforward trajectory generation for flat hybrid automata. Additionally, we provide necessary and sufficient conditions of hybrid automaton flatness for different types of continuous state constraints and switching conditions, and how to compute whether a hybrid automaton is flat. We illustrate feedforward trajectory generation based on our findings for a robotic manipulator example. © 2024 IEEE.

Determining of shear modulus for the samples circular and hollow circular cross-section

The contribution is focused on estimating the shear modulus of the samples of circular and hollow circular sections by static method. The samples were loaded by simple torsion, individual sections were stressed by shear stress. Theoretical basis are determined by linear elasticity and strength theory and they define the relation between shear modulus, maximum shear stress and relative strains. Relative strains are determined by using measurement apparatus and measurement system Quantum X MX 840. © 2016 Trans Tech Publications, Switzerland.

The general scope the present model-based research is to analyse climate-neutral scenarios for Europe and to assess the respective resilience of the energy system. Two scenarios are therefore examined, one with an unrestricted global hydrogen market and the other with improved European energy resilience that limits pipeline imports of hydrogen from non-European countries. Key findings include increasing electrification of the heat and transport sectors, widespread use of Power-to-X appliances and, as a result, a doubling of total electricity consumption in Europe. On the power generation side, there is a need for massive expansion of renewables such as wind and photovoltaics. The analysis shows that a more resilient energy system will require additional electrolysis capacity, hydrogen storage and hydrogen grid capacity. The marginal cost of hydrogen will also increase as a result, and a higher price level will subsequently reduce the demand for hydrogen. The overall conclusion is that a transition from fossil fuels to renewables will, in any case, make the energy system much less dependent on imports and thus more resilient. © Energynautics GmbH.

*** — A Julia Package for Polynomial Chaos in Systems and Control

IFAC-PapersOnLine 2020年第2期53卷 7210-7216页

Polynomial chaos expansion (pce) is an increasingly popular technique for uncertainty propagation and quantification in systems and control. Based on the theory of Hilbert spaces and orthogonal polynomials, PCE allows for a unifying mathematical framework to study systems under arbitrary uncertainties of finite variance; we introduce this problem as a so-called mapping under uncertainty. For practical PCE-based applications we require orthogonal polynomials relative to given probability densities, and their quadrature rules. With *** we provide a Julia software package that delivers the desired functionality: given a probability density function, *** offers several numerical routines to construct the respective orthogonal polynomials, and the quadrature rules together with tensorized scalar products. *** is the first PCE-related software written in Julia, a scientific programming language that combines the readability of scripted languages with the speed of compiled languages. We provide illustrating numerical examples that show both PCE and *** in action.

The content of this article is the proposal of process of the safety analysis for complex dynamic systems. The safety analysis is carried out in process of the proposal of control system for safety-critical processes. In preliminary hazard analysis is done the identifying all possible risks by PHI method. The PHA method is used to analyze these risks. The method of safety analysis depends on various safety-critical states of system which are system are controlled by models. We propose to use the method SQMD for modeling these states. This method combines qualitative and quantitative methods of modeling states and takes advantage of both methods. The model of the proposal is shown in the diagram. The article includes detailed description of the tasks for each step of analysis. © (2013) Trans Tech Publications, Switzerland.

This paper describes one of the parts of our research topic devoted to the image recognition and computer vision. In the field of automation, it is not new, that industry lines are under controls of camera systems. It is necessary to have a clear and visible image for automatic detection of various damages, fails, alarms, objects and right in time control. We divided our research into several stages. In the first stage, we are dealing with the recognition of the blur in the image. We are dealing with classification problem whether the image is blured or in focus. In the initial steps of our research, we have created a dataset of images, which is divided into four categories. In this paper we describe suitable methods to solve this task, we discuss the pros and cons and we also propose our own classification model based on artificial neural networks. © 2020, The Editor(s) (if applicable) and The Author(s), under exclusive license to Springer Nature Switzerland AG.

In our paper we present the method for cross-platform control and monitoring of a device on a production level. Hardware and software inconsistency makes it often difficult to build a consistent and robust control and monitoring environment for a production process. For the purpose of demonstrating this inconsistence and application of our method, we have chose a motor with the frequency converter made by Siemens and the Wonderware platform as the supervisory control and monitoring software environment. In this paper we present the results in a form of proposed hardware setup scheme and software application for supervisory control and monitoring of the device, developed in the Wonderware environment. © Springer Nature Switzerland AG 2020.
