Controller design for point-to-point trajectory generation through feedback linearization of nonlinear control systems
(Universitat Politècnica de Catalunya, 2021-06-02)
Coursework
Open AccessIn this paper some of the most common methods of nonlinear control are explored, firstly introducing the theorems and mathematical background upon which they are built, and then exploring their results. Using a solved ... -
M81 Extragalactic nova explosions
(Universitat Politècnica de Catalunya, 2021-06-04)
Coursework
Open AccessUsing data from the Joan Oró telescope (located in Montsec, Catalonia) and the reference catalogue from Max Planck Institute, we will observe the evolution of different novae in the M81 galaxy. This article explains the ... -
Coverage control
(Universitat Politècnica de Catalunya, 2021-06-04)
Coursework
Open AccessThe focus of this project is on optimal coverage of a given geographical area by means of sen- sors. To this aim, we reproduce a dynamic method to locate the sensors. The implementation is made by gradient descent-based ... -
Point to point control design for the three-link planar robot
(Universitat Politècnica de Catalunya, 2021-06-04)
Coursework
Open AccessIn this paper we design a control for a planar robot arm with three links in the absence of external forces. We begin with an introduction to the physical system and develop the equations of motion from conservation laws. ... -
Characterization of GEN2 PAMAM dendrimers as ETLs for PV cells
(Universitat Politècnica de Catalunya, 2021-06-04)
Coursework
Open AccessSemiconductor electronic devices are fundamental for technology and speci cally for solar cells. Their e ciency is crucial for the actual need of renewable energies and the resistance between semiconductor and metal are ... -

Properties of water and its anomalous behaviour
(Universitat Politècnica de Catalunya, 2022)
Coursework
Open AccessWater is a complex liquid that has unusual behaviours, the most famous being the maximum density at 4ºC. Here in this paper it is reported some of its properties. To do so, molecular dynamics simulations were carried out ... -
Synchronization of complex-valued chaotic systems
(Universitat Politècnica de Catalunya, 2022-06-01)
Coursework
Open AccessSynchronization is a collective behaviour in a complex dynamical network by which the trajectories of all its agents converge to a common state due to the inherent coupling between them plus, in some cases, the existence ... -
Atomic level simulations of disordered matter
(Universitat Politècnica de Catalunya, 2022-05-22)
Coursework
Open AccessThis article presents the results and analysis of classical liquid particle-system simulations and the physical principles behind them. Starting from a lattice of ordered atoms, a Lennard-Jones interaction potential and ... -
Dynamic Feedback Linearizability of Mobile Vehicles with Active Caster Wheels
(Universitat Politècnica de Catalunya, 2022-05-22)
Coursework
Open AccessIn this article, a controller for the non-linear dynamics of a caster wheels vehicle is designed, using the method of dynamic feedback linearization. Numerical simulations of the performance of the controller are included -
Crescentic bars: studying its formation in Castelldefels
(Universitat Politècnica de Catalunya, 2022-06-01)
Coursework
Open AccessCrescentic bars are alongshore rhythmic undulations of sand ridges. Data of a five-camera set up in Castelldefels Beach, bathymetric surveys and wave data from a buoy was used to run and validate the morphodynamic model ... -
Oscillatory regimes in cardiac cells determined by the calcium concentration
(Universitat Politècnica de Catalunya, 2022-06-01)
Coursework
Open AccessSpatial and temporal calcium oscillations within cardiac cells can induce spontaneous excitations alien to the normal pace of the heart, favouring the appearance of arrhythmias. In this work we will study the dynamics ...
