Image processing software for Near Earth Objects (NEOs) detection

Treballs Finals de Grau de Física, Facultat de Física, Universitat de Barcelona, Any: 2014, Tutor: Jorge NúñezThe development of image processing software has been one of the most relevant achievements in astronomy of the last decade. After succeeding to get technical improvement on telescopes and detection systems it was needed to perfect the image processing software in order to make good use of the equipment provided. Matched lter algorithms were implemented within a exible test oriented software which allows the exploration of various scenarios that could arise during the research. These matched lter techniques have proved to be more precise when processing stellar imagery for asteroid detection and tracking. The main purpose of this report is to put into operation the image processing code SALTAD, which stands for SAIC Algorithm Test bed for Asteroid Detection, and compare its results with another image processing software, Visual PinPoint

Large eddy simulations (LES) of the flow past a high-lift wing

Programa de doctorat: Doctorat en Física Computacional i Aplicad

Figuerola de Santes Creus als inicis del segle XVIII segons les fonts fiscals

Treball sobre l'economia agrària del petit terme de Figuerola de Santes Creus, a la Baixa Segarra - com era anomenada a l'època moderna-, avui Figueroleta. La base documental és de naturalesa fiscal, el cadastre, introduït per l'administració borbònica al Principat de Catalunya després de la derrota en la guerra de Successió. El període analitzat abraça des del 1716 fins al 1740. S'estudia tant l'agricultura(conreus i propietat) com la ramaderia, a més de la població

Numerical study of the flow past a three-element high-lift airfoil at different angles of attack

A parametric study of the 30p30n three-element high-lift airfoil is conducted by changing the angle of attack at α = 5, 9 and 23◦ at a constant Reynolds number of Rec = 750, 000. Computational predictions are performed employing large eddy simulations.This work has been partially financially supported by the Ministerio de Economía y Competitividad, Secretaría de Estado de Investigación, Desarrollo e Innovación, Spain (ref.
