Világtendenciává vált a modern oktatásban a virtuális oktatási környezetek alkalmazása és az eLearning. Hazánkban is egyre nagyobb teret hódítanak maguknak a virtuális képzési formák mivel a gazdasági válság új helyzetet teremtett. Az oktatásból történő folyamatos pénzelvonások, megszorítások mellett a hallgatói létszám növekszik. Ennek hatására, e...

A szoftver kritikus sikertényező és mint ilyen alkalmazása szinte minden berendezésben elkerülhetetlen. A skála rendkívül széles a kapucsengőtől a kerékpárlámpán keresztül a járművek fedélzeti rendszerét érintve a nukleáris létesítményekig mindenütt találkozunk szoftverekkel. Sajnálatos módon tapasztalataink azt mutatják, hogy a meg-rendelők-tiszte...

A járművekben a 80-as évek elejétől alkalmaznak mikrokontrollereket, ez az utóbbi másfél évtizedben elengedhe-tetlen tartozéka lett járműveinknek a mindennapi használatban-akár a földi, vízi, vagy légi járműveinket tekintjük. Ez az előadás ezeknek az elektronikus eszközöknek a követelményeknek megfelelő kiválasztásával, alkalmazásával, fejlesztési...

Rohanó világunkban, egyre népszerűbb oktatás irányzat a teljes életen át tartó tanulás (Life Long Learning). A költségvetések így az oktatásé is egyre szűkösebbek. Felvetődik a kérdés, hogy miként lehetne az oktatás színvonalát szinten tartani a költségek emelése nélkül, esetleg csökkentésével? A nyílt forráskódú (Open source) technológiák alkalmaz...

More and more tasks are entrusted to our software. These software perform a number of mission or safety critical tasks in many cases. We have already proven in previous publications that a software cannot be fully tested. Their complexity has already reached a the level that no one human being can understand and review. Human is an unreliable “mach...

Establishment of a proper hemodynamic monitoring system in order to achieve optimal care among critically ill patients is fundamental. In contrast to invasive patient-checking systems, which were introduced decades ago and used in both adult and pediatric intensive care, the non-invasive methods have become more popular in recent years due to techn...

One of the keystones of the smart city is the transportation. The railway is the crucial part in the main public- and also the goods-transportation today, and the significance will be constantly growing. Nowadays the increase in threats and decrease in the sense of security generates a high need for designing smart and multi-level integrated securi...

A szoftver kritikus sikertényező. Manapság nincs olyan bonyolultabb műszaki alkotás, amelyben nincs szoftver támo-gatás. Ez a kijelentés a közlekedésben résztvevő járművekre fokozottan igaz, akármelyik területet is nézzük. Ezek a szoftver elemek megjelennek minden területen a szórakoztató rendszerektől az intelligens forgalomirányítások ke-resztül...

Vehicles, whose functions are enriched with attributes to increase safety, environmental awareness, effectiveness, comfort level and prestige, so that they can play a key role in creating optimal mobility, are now being invented, planned and manufactured for general use. Throughout the full spectrum of transport, vehicles will soon exempt people fr...

Using software became a part of our everyday life, in the last few decades. Software is widely used in areas, such as national defence, aeronautics and astronautics, medicine or even transport. There are 100 million lines of codes in a modern high-end car’s engine control unit. In comparison, the Space Shuttle needs 400 000, the F22 fighter jet nee...

In 2014, a future route was planned between Rotterdam and Vienna, where – in the coming years - they want to realize the first cross-Europe corridor of the cooperative, intelligent transport system. Even in everyday life, we hear about the increased use of autonomous vehicles now. We are now able to come across driverless metros from Budapest to Pa...

The present study examines the driving forces behind smart city implementations. Besides the results of international and European standardization efforts, the importance of holistic approach to cities and the issues of cities as complex systems will also be discussed. Furthermore, the relationship between cyber-physical systems and smart cities wi...

Through the examples of recent accidents in Hungary and abroad, we will reveal the possible reasons for the release of dangerous goods into the environment, and, considering these accidents, we will draw conclusions for the safety of rail transport of dangerous goods. While examining the situation of the rail transport of dangerous goods in Hungary...

One of the main characteristics of a smart city is smart mobility. Therefore, our study focuses on some questions related to smart mobility, especially on the development of intelligent railway. We examine the role of intelligent management systems in the improvement of railway safety. Thus, the present article deals with the reasons for the establ...

The GSM-R system, which is not yet fully implemented in Hungary, will undoubtedly bring about significant changes to the Hungarian railway. These changes give rise to numerous questions — even to specialists — in connection with its future operation. The purpose of this article is to give an overview on the present state of the implementation of th...

In the present study the motivation for developing an intelligent system in transportation is discussed. With regard to the driving forces, the aims of developing the smart systems in the future will be explored. The basic concepts of the envisioned system are defined in order to avoid any problems with creating the real model. The technical and te...

Continuous Glucose Monitoring (CGM) has become an increasingly investigated tool, especially with regards to monitoring of diabetic and critical care patients. The continuous glucose data allows the calculation of several glucose variability parameters, however, without specific application the interpretation of the results is time-consuming, utili...

Amplitude-integrated electroencephalography (aEEG) is a useful tool to determine the severity of neonatal hypoxic-ischemic encephalopathy (HIE). Our aim was to assess the prevalence and study the origin of false normal aEEG recordings based on 85 aEEG recordings registered before six hours of age. Raw EEG recordings were reevaluated retrospectively...

This paper proposes a new control structure for automatic production lines. To handle the production lines flexibility and to solve the optimal control problem a new methodology is suggested. In our approach the production line workstations are connected sequential, coordinated and controlled with individual (industrial) Personal Computers (PCs) in...

It is usually supposed that tolerance levels are determined by the decision maker a priori in flexible linear programming (FLP) problems. In this paper, we shall suppose that the decision maker does not care about the particular values of tolerance levels, but he wishes to keep their sum below a predetermined level which we call his overall flexibi...

This paper contains a description of simulation software, which has two parts. The first part is about the simulation of physical object such as the four-wheel steered mobile robot. The second part is about the control algorithms. It also contains some results of the simulation and some developing consideration related to the software and positioni...

Some stations of production line have longer cycle time than the pro-duction period of the whole production. In these kind of cases parallel processing methods has to be applied. Scheduling of this method can have several problems, therefore it is very important that the geometrical layout and control meet all the requirements. Our suggestion shows...
