Projecte Final de Màster Oficial
Accés restringit per acord de confidencialitat
Realitzat a/amb: Hewlett Packard EspañolaWe consider a system architecture where the communication between the remote devices and a central controller is done using a custom application protocol on top of CAN. CANopen is a communication protocol based on CAN that ... -
A canvas for the ethical design of learning experiences with digital tools
(Universitat Politècnica de Catalunya, 2022-09)
Text en actes de congrés
Accés obertThe use of digital tools has drastically increased in engineering education, accelerated by the COVID-19 pandemic. These tools generate important ethical issues, in particular in terms of privacy and fairness. However, ... -
A capacitated commodity trading model with market power
(Universitat Politècnica de Catalunya, 2008-02)
Projecte Final de Màster Oficial
Accés obertThis Master Thesis proposes an analytical model of commodity trading in the presence of market power, which is new to the literature. We establish the rational behavior of traders between two markets and derive price ... -
A carrier based approach for overmodulation of three-level neutral point clamped inverter with zero neutral-point current
(2012)
Text en actes de congrés
Accés restringit per política de l'editorialIn a voltage source inverter, overmodulation is required to extend the range of operation and enhance the dclink voltage utilization. A carrier-based implementation of a modulation strategy for the three-level ... -
A carrier-based PWM strategy with zero-sequence voltage injection for a three-level neutral-point-clamped converter
(Institute of Electrical and Electronics Engineers (IEEE), 2012-01-09)
Article
Accés restringit per política de l'editorialPerformance of a carrier-based pulsewidth modulation (CB-PWM) strategy can be improved by the inclusion of a zero-sequence voltage in the modulation-reference signal. This paper proposes a new CB-PWM strategy for a three-level ... -
A Cartan-Eilenberg approach to homotopical algebra
(2008-09-01)
Article
Accés obertIn this paper we propose an approach to homotopical algebra where the basic ingredient is a category with two classes of distinguished morphisms: strong and weak equivalences. These data determine the cofibrant objects ... -
