Continuous-Curvature Paths for Mobile Robots
(Budapest University of Technology and Economics, 2009)
This paper discusses how to plan continuous-curvature paths for car-like wheeled mobile robots. The task is to generate a trajectory with upper-bounded curvature and curvature derivative. To solve this problem we use three ...
Analyses of the grid resistance measurements of an operating transformer station
(Budapest University of Technology and Economics, 2009)
This paper presents a non-conventionally installed HV/MV underground substation from the point of view grid resistance. The effects of the infeed high voltage (HV) cables and the connected medium voltage (MV) distribution ...
Circumstances affecting the protection against electrode potential rise (EPR)
(Budapest University of Technology and Economics, 2009)
In this paper the grid resistance of substations with different earth electrode and soil structures is investigated by simulation studies with the use of CDEGS (Current Distribution, Electromagnetic Fields, Grounding and ...
3SC Control for high efficiency grid connected photovoltaic converters
(Budapest University of Technology and Economics, 2009)
Nowadays there are several grid connected converters in the grid system. These grid connected converters are generally the converters of renewable energy sources, industrial four quadrant drives and other converters with ...
Modelling and Calculating the Harmonic Penetration of the High Power Traction Usind the Double Domain Simulation
(Budapest University of Technology and Economics, 2009)
The paper presents the results of a long term research work. The authors are modelling the penetration and elimination of harmonic disturbance originating from the high power railways. This kind of problem is usually handled ...
Combining Description Logics and Object Oriented Models in an Information Framework
(Budapest University of Technology and Economics, 2009)
We present an information integration system called SINTAGMA which supports the semantic integration of heterogeneous information sources using a meta data driven approach. The main idea of SINTAGMA is to build a so called ...
Rain attenuation time series synthesis with simulated rain cell movement
(Budapest University of Technology and Economics, 2009)
This paper proposes a stochastic modeling method to simulate the rain attenuation process in order to generate time series for high frequency terrestrial radio links. It is also the subject of this research to express the ...
Human subject experiments for investigating the combined effects of two local discomfort parameters
(Budapest University of Technology and Economics, 2009)
The purpose of HVAC systems is to provide a comfortable environment and set the conditions for efficient work. The enhancement of buildings´ energy performance puts emphasis on meeting the comfort requirements indoors, as ...
Thermal comfort of closed spaces. Fundamentals of static and dynamic heat balance of human body
(Budapest University of Technology and Economics, 2009)
The growing mechanization and industrialization of society has resulted in most people spending greater part of their lives - 85-90% - in artificial climate. In this climate, thermal comfort can be basically predicted by ...
Experimental and numerical study on cavitating vortex shedding behind a square cylinder
(Budapest University of Technology and Economics, 2009)
Comparison between experimental and numerical results of the cavitating vortex shedding behind a square cylinder is presented. The side length of the experimental and numerical model was 25 mm and 20 mm, respectively. The ...
