This paper describes a solution to decrease maintenance costs for the Éole Bridge expansion joints. The developed monitoring system is based on the analysis of the sound level and frequencies produced by the vehicles passing in these expansion joints, allowing an estimation of the joint overall structural damage. The system issue alerts to maintenance teams, improving their response time and preventing...
Conserving earth's biodiversity for future generations is a fundamental global task, where automated recognition of pollen species by means of computer vision represents a highly prioritized issue. This work focuses on analysis and classification stages. The morphological details of the contour are proposed as pollen grains discriminative features. The approach has been developed as a robust pollen...
This paper summarizes the results of research tasks in the field of physiological modeling and control of diseases with high public health impact carried out by the Biomedical Engineering Laboratory of the Budapest University of Technology and Economics. The developed and presented optimal algorithms and strategies focus on three diseases with high public health impact diabetes (the question of artificial...
Tissue engineering's main objective is to create therapeutic constructs in vitro, capable to replace or remedy the functions of the tissue affected by different disease or totally destroyed. In order to obtain these constructs, the living cells are cultured on the different structure biomaterial. It has been shown that these constructs have properties which are similar to ones of human tissue, if...
Medical images carry information in a complex data format about the organ and the related pathologies. Physicians must decipher this information from the image. In this paper a workflow of the image interpretation simulation and a set of numerical image processing algorithms are presented. The paper is focused on the available segmentation and feature extraction methods. The main goal is to create...
The paper presents an ICT tool to support the physicians in their clinical activity assessing and monitoring the cases which lead to preterm birth. The basic ICT tool is an open source called Labkey Server which has the ability to make statistics, reports and other important charts which can help the clinicians and the researcher to prevent the preterm birth. The data will be gathered from multiple...
Definition of product in model space includes contextual decisions and relies upon background of those decisions. This background influences decisions on engineering objects in a very complex way. Appropriately selected combination of engineering object variants may be a compromise in a coordinated product definition. The authors of this paper recognized that conventional model space construction...
Project management information system is one of main enablers of successful project management. The configuration of the project management information system should be adapted to needs and requirements of a particular project. However, project managers are not always aware of the most appropriate configuration. Adequate knowledge would help the project managers during definition of the configuration...
Near Field Communication (NFC) is one of the latest wireless communication technologies, making possible variety of novel services on mobile equipments. At Budapest University of Technology and Economics (BME) a generalized approach for NFC application development has been elaborated, where applications can be implemented and executed in a common environment. We have developed the prototype of an...
The paper deals with modeling and diagnostics of complex systems. In the area of modeling, the authors describe dynamic models of dependence of speed upon fuel flow supply of a small turbojet engine MPM-20. The first model is done with use of neural networks and the second is a linear model. Both models are then methodologically incorporated into the diagnostic and backup system of the optical sensor...
The approximation methods of mathematics are widely used in theory and practice for several problems. In the framework of the paper a novel tensor-product based approach for representation of neural networks (NNs) is proposed. The NNs in this case stand for local models based on which a more complex parameter varying model can numerically be reconstructed and reduced using the higher order singular...
In the PhD dissertation [6] optimization models were developed for the pavement management system, which could help planning the optimal maintenance work. This model can be generalized for those engineering structures, where there are several types of structures and for each structure there are many components with many different types of deterioration options and duty uses. The condition of application...
Paper presents project of experimental gearbox design and production with application of Rapid Prototyping technology realized by students and workers of Faculty of Manufacturing Technologies in Presov, Slovakia. In frame of gearbox design there was model with four gears realized together with its control mechanism. Production of gearbox was connected with realization of produced parts dimensional...
The program for machine is important for creation a new parts in industry. In this time, the NC (numerical control) is very used. NC is technology, in which the program for controlling of the machine is used; for example for drilling, lathes, milling, conventional and unconventional cutting machines (laser, water-jet, plasma). CNC programming may use the application of Group Technology theory. Group...
This paper introduces a new approach to integrated education of engineering. For this purpose the authors studied higher education and industrial product modeling and proposed an integrated approach where higher education course and production equipment modeling are integrated with the controlled job floor automation environment. For the purpose of this environment, flexible manufacturing system was...
