The objective of this document is the determination of the maximum power point using the best suited algorithm on the environment Psim. The photovoltaic panel will be modelled by a diode and two resistances, the first on will be put in parallel, the second one will be put in series. The output of this model will be composed of the current, voltage, and the power. We added a DC-DC boost converter which...
As an integral part of the Ethernet standard IEEE 802.3, the Ethernet Powerlink protocol is widely used in the automation industry. It is a software-based solution and achieves some real-time capabilities. It satisfies data transmission demands by guaranteeing communication with very high speed and accuracy. In effort to make implementing Powerlink protocol easier, we build a formal Powerlink model...
Improving a reliability of electrified railway operation system requires protection against overvoltage, particularly those of atmospheric origin. The most serious threat to the traction system is lightning when it strike the mast or conductors. to protect a system from this phenomenon, the ZnO arrester are used.
Predicting the capacity of wireless mesh networks is difficult, due to the complex interaction of various layers such as the radio environment, media access protocols, network protocols and, traffic load and types. When modelling and simulation takes into account the interaction of all these factors, it can facilitate insights into anticipated network behaviour. These insights can be used to more...
This paper presents the simulation of different types of single as well as composite power quality events (PQ) for analysis and characterization. Most of the power quality problems (the transient and steady state disturbances), which can occur in the distribution system, have been obtained. Six single PQ event such as voltage sag, voltage swell, interruption, transients, voltage notch and harmonics...
Availability of hardware implementations of super-resolution image reconstruction algorithms is limited mostly by their logical and memory requirements. This is also the case for other image processing algorithms such as hyperspectral, image compression, image coding, video coding. In previous publications we have introduced a new execution flow that tackles the problem of high memory requirements...

Approximate functions for parasitic elements of the device have been proposed.
Interaction between humans and robots is expected to increase in the coming years. In order to ensure safety for the robot, its environment, and the people around it, it is necessary to have robust compliance actuation. Mechanically compliant devices such as magnetorheological actuators can ensure a high degree of safety through their intrinsic properties. This paper presents the modelling of a new...
In this paper, a study of the evolution and the characterization of the Uruguayan vehicle fleet is presented.

Gas turbines are one of the most important internal combustion engines in the modern world's transportation. Any possible improvements of the performance of the gas turbine engines would help to minimize the world's annual fossil fuel consumption and hence the emissions of the adverse greenhouse gases. Therefore, modelling and simulation of gas turbines have been a major focus of many fields in aviation...
The grid-tied low voltage photovoltaics are expanded day by day. Aiming for a high penetration level, the Fault Ride Through Capability (FRTC) standard should be extended to these units as well. In this paper, the behavior of Single Phase Grid Connected PV Systems under faulty conditions is investigated. For this purpose, a SPWM controlled full bridge voltage source inverter is used. The proposed...
Large IGBT modules often consist of many IGBTs connected in parallel in order to achieve high current ratings. In the ideal case, current is shared equally between these IGBTs. However, in real power modules parasitic oscillations between the IGBTs can occur, which can lead to EMC issues or even damage the power module. In this paper, two different oscillation circuits are presented which have been...
