Industrialització i fabricació d'una carrosseria d'un vehicle de baix consum

El projecte es desenvolupa amb la intenció de millorar ell cotxe queparticipa, en nom de la Universitat de Girona, a la shell eco-marathon en lacategoria de prototips i amb gasolina com a combustible.El motiu principal que ha donat peu a aquest projecte és la realització d’unestudi aerodinàmic que ha desembocat en un disseny totalment nou de lageometria de la carrosseria. Aquest estudi i el disseny aerodinàmic de lacarrosseria obtingut es pot consultar al projecte titulat “Disseny i estudi del’aerodinàmica del vehicle àliga” de l’autor Albert Marron

Vehicle WiFi

El projecte presenta el disseny d'un vehicle a motor elèctric construït sobre el sistema microcontrolador LPC1769 amb comunicacions sense fils via xarxes WiFi i detecció d'obstacles per sonar.

Association between GIS-based exposure to urban air pollution during pregnancy and birth weight in the INMA Sabadell Cohort

Background: There is growing evidence that traffic-related air pollution reduces birth weight. Improving exposure assessment is a key issue to advance in this research area.Objective: We investigated the effect of prenatal exposure to traffic-related air pollution via geographic information system (GIS) models on birth weight in 570 newborns from the INMA (Environment and Childhood) Sabadell cohort.Methods: We estimated pregnancy and trimester-specific exposures to nitrogen dioxide and aromatic hydrocarbons [benzene, toluene, ethylbenzene, m/p-xylene, and o-xylene (BTEX)] by using temporally adjusted land-use regression (LUR) models. We built models for NO2 and BTEX using four and three 1-week measurement campaigns, respectively, at 57 locations. We assessed the relationship between prenatal air pollution exposure and birth weight with linear regression models. We performed sensitivity analyses considering time spent at home and time spent in nonresidential outdoor environments during pregnancy.Results: In the overall cohort, neither NO2 nor BTEX exposure was significantly associated with birth weight in any of the exposure periods. When considering only women who spent < 2 hr/day in nonresidential outdoor environments, the estimated reductions in birth weight associated with an interquartile range increase in BTEX exposure levels were 77 g [95% confidence interval (CI), 7–146 g] and 102 g (95% CI, 28–176 g) for exposures during the whole pregnancy and the second trimester, respectively. The effects of NO2 exposure were less clear in this subset.Conclusions: The association of BTEX with reduced birth weight underscores the negative role of vehicle exhaust pollutants in reproductive health. Time–activity patterns during pregnancy complement GIS-based models in exposure assessment.

Some applications of FISST to wireless communications

This paper aims at illustrating some applications of Finite Random Set (FRS) theory to the design and analysis of wireless communication receivers, and at pointing out similarities and differences between this scenario and that pertaining to multi-target tracking, where the use of FRS has been traditionally advocated. Two case studies are considered, l.e., multiuser detection in a dynamic environment, and multicarrier (OFDM) transmission on a frequency-selective channel. Detector designand performance evaluation are discussed, along with the advantages of importing FRS-based estimation techniques to the context of wireless communications.

Vehicle de guiat automàtic (AGV)

Aquest projecte documenta la simulació d'un AGV (vehicle de guiat automàtic). Mitjançant un robot educatiu programat en Basic Stamp es simula un entorn d'anàlisi clínic a on el robot gestiona de forma automàtica les estacions d'anàlisi d'una hipotètica mostra de sang.
