Article deals with design of distributed control of hotair unit. It is describes equipment of hot-air unit and its possibilities. There are information about distributed control and about unit - server connection and about server - client connection. For the remote control hot - air unit via Internet was used the duplex web service. This duplex service contains methods for receiving buffered data...
The paper explores possibilities of applying the IR thermography for integrity evaluation and quick detection of failures in natural gas delivery stations. The natural gas stations typically comprise overground facilities for filtering, pressure reduction, flow metering and odorizing. The facilities and the interconnecting pipelines are subject to risk of damages due to material failures or external...
For process control two basic approaches are used: outside - in approach and inside - out approach. Outside-in approach is user oriented. Process is forced to satisfy user objectives. Inside-out approach is process oriented. At this process driven approach process has dominant position and conditions have been created to realize it by the most natural way. Process oriented approach is based on knowing...
Excavation of various underground structures, such as tunnels, caverns and linear mining structures using the tunnel boring machines (TBMs) has become an ultimate technology in underground construction in recent decades. Construction of TBMs has been improved over the years and still is being refined by introducing novel progressive materials. Technological processes of excavation have passed through...
Emission reduction, this expression is one of the most frequently used in the last years. Its meaning is known very well for the ordinary people, ordinary in the sense of being not associated with the automotive industry. One of the strategies for NOx emissions reduction in personal vehicles with combustion engine is the Selective Catalytic Reduction System. The critical issue of such systems can...
Mathematical models serve as a basic tool for information gaining about technological objects and processes. Suitable mathematical model, which can be effectively used as a integral part of the process control system, requires not only adequacy to the modeled objects but also adequacy of the computing time to the real time, because one of the main criteria of the optimal model is its time saving....
The purpose of this work is to design the system, which eliminates redundant and repetitive tasks in the certain types of hearing function examinations. Proposed system reduces time needed to examine patient and also provides the full digitization of the results. The obtained database can recently become the base for subsequent processing in artificial intelligence expert systems. Such systems can...
It is considered a non-standard model for the overhead (gantry) crane where two basic simplifying assumptions are overruled: negligible distributed mass of the rope and negligible acceleration of the load mass with respect to the gravity acceleration. Especially the last assumption (valid at each time moment) is difficult to check theoretically. The model thus obtained completes a previous one and...
The aim of paper is focused on principle and architecture of real time application core for dynamic multiaxial testing on hydraulic platform. There is used an approach with HW and SW from Nationall Instrument (the real-time PXI platform and LabView development SW). In the paper will be presented internal architecture of SW and HW for real-time 12 parallel control loops.
The paper is devoted to the tuning of analog and digital PI and PID controllers for the first order plus time delay plants. The described method is fully analytical. It is based on the multiple dominant pole method and compensation. The described controller tuning method makes possible to obtain a non-oscillatory control process without an overshoot for all input variables. The use is shown in the...
This paper is focused on testing vehicle frame assist in experimental modal analysis. For analysis we will use data from net of three axis MEMS accelerometers. Net of sensors is connected by CAN bus. This measure system can work during ride of vehicle, it means that is enable analyze process instant during ride on road.
This paper presents a prototype of a multi-robot reconnaissance system for detection of chemical, biological, radiological, nuclear, and explosive (CBRNE) threats. Different robot platforms are able to carry highly modularized payload platforms: either a multi-purpose CBRNE sensor suite or a mobile manipulator for semi-autonomous sample collection. A variety of sensors is available for detection and...
In the paper we present theoretical and experimental results of two variants of contactless thermal analyzer (CTA) for determination of specific heat capacity, thermal diffusivity and thermal conductivity for different sample sizes. Measuring system under investigation is fully automatic (including of sample illumination), contactless and relative precise (sensitivity ∼ units of percent). Results...
The aim of this article is to compare possibilities of the ontology usage in automation. In the first part there is the ontology definition and its generic form discussed as well as the connection between ontology and semantic web. In the second part, there are shown the possibilities of the ontology usage in automation, especially usage of ontology as metadata storage. The last part of the paper...
The paper describes the 3-dimensional trajectory planning editor which supports the consequent real-time generation of the robot effector path using motion control technology (PLCopen standard). The presented 3D editor is powered by modern open technologies and enables users to simply view, edit and simulate the final trajectory. Moreover, the role of the editor in the whole robot control chain is...
The influence of non-uniform magnetic field on the beam with magnetorheological fluid is used to build the vibration control algorithms. A special laboratory stand with appropriate electromagnet was built to test free and forced vibrations of the beam with and without control. Experiments were done to determine the stiffness and damping parameters of the beam for various currents flowing in electromagnet...
This paper introduces the Fractional Variable Order Discrete System, described in the state space. The paper also introduces results on the controllability, reachability, observability and stability of that system. The definitions of the notions of controllability, reachability and observability for such models are proposed and the necessary and sufficient conditions for reachability and observability...
This paper describes the processing of photographs in the newly created module for 2D modeling, which will be integrated into the system FOTOMNG. This is a usable application in medicine to analyze images of probes and non-invasive examination developed at the department of computer science of the technical university of Ostrava. The module will be his purpose and functionality to build on a previous...
The article discusses usage of an innovative three-dimensional vision system in a quality control process for surface defect detection. A method of 3D image building and selecting cross section profile on 3D images is presented. The article discusses problems connected with the resolution of the 3D vision system, resolution of the laser beam analysis, and resolution connected with the application...
Nowadays ontologies are more and more often put on work in diverse industrial areas thanks to their high potential of applying. In this paper we extend work of other developer groups that are interested in ontologies and purvey frameworks for ontology using. To make clear meaning of ontology, we describe it with a set of properties that points out its diversity. Next we focus on possibilities of using...
