Forecasting and analyzing urban car traffic is an actual but still very complex problem. The modern car fleet handling IT systems designed for taxi and delivery service companies allows GPS coordinate data acquisition from large amount of vehicles for optimizing the ride and freight allocation. Since the database of these companies contains movement patterns belonging to multitude of vehicles, arise...
In this study we introduce a Linear Parameter Varying (LPV) based controller design possibility for LPV systems with state and input uncertainties. Through the LPV framework the developed method can be used for the nonlinear system belongs to the given LPV system. The controller design approach effectively exploits the combination of the classical state feedback and matrix similarity theorems in order...
The purpose of this paper is to present a Robust Nonlinear Model Predictive Control controller design opportunity and the results of three in silico test scenarios, where a nonlinear glucose model had to be controlled, and a desired blood glucose level had to be maintained. The chosen glucose model was a two compartmental, nonlinear model with time delay whose parameters were burdened with uncertainty...
The development of the technical devices of today is nearly impossible to follow. From all of these devices, drones received the highest publicity. The results of this fast-paced development is certainly favourable to hobby aviators and professional users as well. However this fast spreading brings up many questions on the technical side, for example the safe and stable communication is concerned...
We share almost all segments of our lives on the web, including our to-do's, meetings, events related to work or leisure. Not only we share with the world where we are going to be, but also how we are feeling in a given situation and with whom we are attending a certain event. If we ignore the individual aspect and look at a city as a whole, the people, who work and enjoy their free time in the city...
The current trend of urbanization involving changes within the activities in a city has created several problems. Addressing these problems requires reliable and detailed information regarding urban structure and related dynamics. This study uses mobile phone Call Detail Records (CDR) data collected from cellular towers in Győr, Hungary. First, our method began with the pre-processing of the telecom...
