    Nowadays when traffic jams and air pollution are very common, controlling the emission rate of the exhaust fumes is a significant task. Many difficulties make this problem more sophisticated, for example the present emission models sometimes need too many information so it is quite complex to work with them. On the other hand, the underlaying physics behind the hydrodynamic traffic models does not suggest unique mathematical formulation so we need adaptive controllers that iteratively improve the forecasts obtained by a rough initial model without tuning the parameters of a particular mathematical structure. In this paper a simple method is shown for determining the stationary solutions obtained from a hydrodynamic model for a realistic parameter range. The method is based on Robust Fixed Point Transformations (RFPT)-based adaptive control that needs only the main factors in the emission: the traffic density and velocity. For controlling it applies electric road signs for the prescribed velocities and allowed ingress rate from the ramp in the preceding sector. This is a new area for the RFPT, but as the simulations show it is successfully applyable to the problem. View full abstract»

    The AERObot autopilot for small and medium size unmanned aerial vehicles (UAVs) developed at Óbuda Universtiy has multiple control systems. It is possible to switch between the control systems even during in flight. The purpose of the current research was to examine the applicability of full fuzzy flight control (takeoff, cruise and land) in unmanned aerial vehicles instead of partial or hybrid control [1, 2, 3]. The easy tuning of the parameters and features is quite important because one autopilot should control different sized and designed planes. Since the safety of the flight, life and value is the most important, real test flights should always be performed after many hours of computer simulation. For this purpose Hardware In the Loop simulation was used. The advantage of this simulation is that the very same environment can be created as in real flights (e.g. atmospheric, aerodynamic, propulsion model, different weather conditions). After successful simulations the real test flights can be started. View full abstract»

    The purpose of this article is to perform an in-depth analysis of the classical double inverted pendulum system using the Inverted Pendula Modeling and Control (IPMaC), a Simulink block library designed by the authors of the paper. The custom function blocks included in the IPMaC offer comprehensive program support for the modeling, simulation and control of classical and rotary inverted pendula systems. The library also incorporates software tools which provide a user-friendly graphical interface (GUI) to modeling and linearization procedures. With the aid of appropriate function blocks, GUI tools and demonstration schemes from the IPMaC, the classical double inverted pendulum system is analyzed, modeled and successfully stabilized in the unstable inverted position.

    The Minnesota Code is a hierarchical rule-based system for the evaluation of reference ECG signals. One of its weaknesses is the crisp value based hierarchy system. The proper and effective modeling of the rule hierarchy is the key point of the Minnesota Code. In this paper the authors present a possible method to improve the decision model of the Minnesota Code by applying fuzzy ontology to represent the decision process as a hierarchical description of important classes (concepts) along with the description of the properties (of the instances) of each concept.

    Local Governments use multiple IT methods and tools to provide services required. Chosen business processes and software products should certainly provide suitable and reliable applications for long term. Nevertheless, due to the sudden change and improvement of IT Technology, some solutions become obsolete and those should be replaced sooner or later. However, as sustainability is requested in Local Governments, such changes have to be handled carefully. A new Business Process Reengineering, BPR, methodology is being built to support Local Governments-specific IT change and technology management. This paper introduces our methodology applied to an initial SAP business process implementation project. A mini-SAP project is defined to complete the so-called Business BluePrint phase of SAP ASAP Methodology. This approach is found to be suitable to support the Local Governments BPR project.

    In this paper a fuzzy logic-based hierarchical multilevel risk calculation model will be introduced with different model parameters. On each occasion when a fuzzy-based simulation model is constructed, the appropriate aggregation and defuzzification method must be chosen. It is very difficult because it cannot be said generally, which is the best method, its depends on the current application. The model presented in the paper is a model for risk calculation of physical exercise, and it was constructed in Simulink - Fuzzy Logic Toolbox environment with Mamdani-type fuzzy evaluation and different aggregation and defuzzification operators. The test was performed for several typical groups of the patients. The results are compared with a previously implemented Analytic Hierarchy Process with Fuzzy Comprehensive Evaluation based model with similar purposes. The result of the comparison has been analyzed and the best methods have been selected. View full abstract»

    The radar system utilized for through wall detection and tracking of multiple targets often cannot detect all of them. It results from the fact that the targets which are moving close to the radar antenna system absorb the large amount of energy and the electromagnetic waves reflected from the other targets have small magnitude. This problem can be redeemed by use of the weak signal enhancement methods in combination with proper target detectors. In this paper, six methods which three new are described and tested with the combination of different CFAR detectors. The achieved results confirm the ability of weak signal enhancement methods to improve the result of radar detection. View full abstract»

    Cancer diseases are one of the most lethal, incurable diseases today, thus fighting cancer is an actual and urgent problem in clinical practice. Beside classical therapies, a new approach is represented by model-based therapies, where human body works as a complex system. These therapies are called targeted molecular therapies (TMTs). TMTs are fighting specifically against different cancer mechanisms and usually don't eliminate the whole tumor, but control the tumor into a given state and keep it there. The aim of antiangiogenic cancer therapy is to prevent tumors from forming new blood vessels, because without angiogenesis tumor growth is inhibited. In this paper we analyze a nonlinear tumor growth model and design linear controllers based on a linear model acquired from working point linearization. Realized controllers are state feedback with pole placement, LQ control method and both controllers with state observer. Simulations are carried out and the controllers are analyzed in many aspects, including the working points used at linearization. View full abstract»
