This contribution has two main objectives: On the one hand, we want to introduce survival analysis techniques for use in building maintenance and, on the other hand, to apply this methodology to analyzing a large building stock in order to obtain information for maintenance strategies and/or prevention policies.
Similar to technical systems, buildings and their elements are also subject to aging. They age even faster when they are exposed to external (sometimes extreme) weather conditions. In this paper we are particularly interested in describing the time to the event when the event of interest is some damage (or level of degradation) on the building façade which can represent some risk for people (inside or outside the building). For the time being, building follow-up is based on inspections. Data coming from building inspections is always inaccurate, but censored, due to the fact that, at each inspection time, the event of
interest has already happened, or not yet happened. We have adapted the existing methodology for fields like medicine, biology, industrial engineering or event history analysis, and we have implemented in SPLUS®, by Insightful®, the routines for a numerical and graphical systematic analysis.
The potential of this proposal is illustrated with its application to a real dataset. We have been collecting data for years from all the buildings façades in Hospitalet de Llobregat, the second most populous city in Catalonia (Spain). More than 10,000 buildings have been inspected and an exhaustive checklist has been completed for each one. The analysis of the results allows technicians to detect different zones and levels of intervention to be applied in the city.

L’Institut d’Estadística i Matemàtica Aplicada a l’Edificació (IEMAE) recull propostes en el sector de l’edificació sostenible de professors de diferents departaments de l’EPSEB de forma transversal i en aquest context dinamitza i dóna suport a l’activitat dels seus membres en l’àrea de l’Estadística i Matemàtica Aplicada orientades a noves metodologies i les seves aplicacions. Dins del Seminari de l'Institut trobem l'exposició en català a càrrec del Carles Serrat i Pié professor del departament de Matemàtica Aplicada I (EPSEB-UPC).

En la producció d’EmmyNoetherse solen distingir tres períodes:
del 1908 al 1919 en què es dedicà a la teoria d'invariants, teoria de Galois i càlcul de variacions; del 1920 al 1926 en què el seu estudi se centrà en els anells commutatius i la teoria d'ideals; i del 1927 al 1935 en què el seu treball tingué com a eixos principals els sis temes hipercomplexos i la representació de grups.

En la nostra presentació parlarem d’aquest tercer període i del seu impacte en teoria de nombres. Noether ho resumiria així: la repercussió de la no commutativitat en la commutativitat.

Aquesta conferència es troba dins del Seminari de l’Institut d’Estadística i Matemàtica Aplicada a l’Edificació.

Starting with a look at Hilbert's famous 1890 paper, which was considered at one time to have dealt the deathblow to Invariant Theory, and which inluded the famous Basis Theorem and Syzygy Theorem, we will trace some developments in commutative noetherian ring theory such as the Hilbert Function, homological dimension, global dimension of local rings, determinant alvarieties,and then make a natural return to some of the rings of invariants studied in that same Hilbert paper. While this arc will constitute the main structure of the talk,I may digress into some other related areas,such as characteristic-free representation theory of the general linear group.
