A simplified model for bottom trawl fishing gears

Computational modeling is a valuable complementary tool to assess behavior of bottom trawl fishing gears. A simplified model of the gear that mainly affects to the net is proposed. The model is constrained to steady towing conditions, flat seabed and gear symmetry. Simulations proportionate a number of relevant outcomes like distribution of tensions at the warp, balance of forces at the otterboards or spread under different haul conditions such as depth or towing speed. In this paper we mainly focuss on the description and implementation of the model. Nevertheless, some preliminar comparison with experimental data is also shown

Recursos docents de matemàtiques i estadística (Una base de dades, comentada, de material docent a la xarxa)

L’objectiu del projecte consistia en dissenyar i elaborar una base de dades, fàcilment consultable, que recollís informació sobre recursos docents accessibles a través d’Internet, en els àmbits de les matemàtiques i l’estadística. La consulta de la base de dades s’havia de poder fer també des de la xarxa i amb opcions de cerca anàlogues a les dels catàlegs de les biblioteques. Es volia també que la informació recollida no fos totalment neutra i incorporés descripcions i comentaris que poguessin ser útils pels usuaris: professorat, alumnat i PAS. Es tracta d’un projecte conjunt entre professorat del departament de Matemàtica Aplicada IV i la biblioteca de la Facultat de Matemàtiques i Estadística

DISPAR: A tool to model bottom trawl fishing gears

Marine Technology Workshop (Martech05), 17-18 November 2005, Vilanova i la Geltrú, Barcelona.-- 1 pageBottom trawl fishing is a relevant extractive economic activity. However, the limitation of resources and the impact on the environment demand for a more rational exploitation in order to render the activity sustainable and productive in a near future. To this purpose it is important to understand and to analyze the behaviour of fishinggears. DISPAR is a collaboration project betweenthe UPC-CTVG and the CSIC aimed to movetowards this direction.

Characterization of coastal upwelling events during the generation of the water column stratification in spring (Vilanova i la Geltrú, NW Mediterranean)

This article presents some preliminary results on the characterization of inputs of offshore waters (upwelling events) in the coast off Vilanova i la Geltrú (NW Mediterranean) in the spring of the years 2010, 2012 and 2014. The upwelling events are studied in terms of meteorological and oceanographic conditionsPostprint (author’s final draft

Retirement Investing: A New Approach

This paper proposes a new approach to investing for retirement that takes advantage of recent market innovations and advances in finance theory to improve the risk/reward opportunities available to individual investors before and after retirement. The approach introduces three new elements: 1. It uses inflation-protected bonds to hedge a minimum standard of living after retirement; 2. It takes account of a person’s willingness to postpone retirement, and 3. It uses option “ladders” to lever growth in retirement income

Breeze influence on waves and vertical current profile in the coastal area based on EOF analysis (Vilanova i la Geltrú, Barcelona)

This article presents some preliminary results on the breeze influence on waves and vertical current profiles during eleven months of data recorded by an Acoustic Wave and Current Profiler installed in the OBSEA platform in the coast of Vilanova i la Geltrú (NW Mediterranean). The collected data has been analyzed using Empirical Orthogonal Functions and spectral analysisPostprint (published version

Aprendre matemàtiques dissenyant

Matemàtiques per al disseny és una assignatura de l’EPSEVG (UPC). S’hi presenten els fonaments matemàtics del disseny industrial. Explicarem com hem incorporat la metodologia aprendre fent. A banda d’il·lustrar tots els conceptes amb objectes quotidians, basem l’aprenentatge en el treball per projectes. Això permet incorporar la creativitat dels estudiants i afavoreix la seva implicació. A més, hem usat les xarxes socials com a mitjà de comunicació.Postprint (published version
