Aquest projecte es centra en el municipi d’ Itacaré (Bahía, Brasil), el qual actualment pateix una creixent demanda de turisme pel seu atractiu natural. Aquest municipi no disposa de cap Pla de Gestió del Turisme. Per aquest motiu i juntament amb l’ ONG del Brasil “Instituto Aliança” s’ ha treballat en un projecte de creació d’ un centre d’ atenció al visitant. Aquest “Centre de atendimento a ou visitante” està encarat bàsicament a informar i sensibilitzar als turistes i als propis natius de la zona, de les característiques ambientals i culturals de la regió, alhora que es potencia un turisme de base comunitària

Most network operators have considered reducing Label Switched Routers (LSR) label spaces (i.e. the number of labels that can be used) as a means of simplifying management of underlaying Virtual Private Networks (VPNs) and, hence, reducing operational expenditure (OPEX). This letter discusses the problem of reducing the label spaces in Multiprotocol Label Switched (MPLS) networks using label merging - better known as MultiPoint-to-Point (MP2P) connections. Because of its origins in IP, MP2P connections have been considered to have tree- shapes with Label Switched Paths (LSP) as branches. Due to this fact, previous works by many authors affirm that the problem of minimizing the label space using MP2P in MPLS - the Merging Problem - cannot be solved optimally with a polynomial algorithm (NP-complete), since it involves a hard- decision problem. However, in this letter, the Merging Problem is analyzed, from the perspective of MPLS, and it is deduced that tree-shapes in MP2P connections are irrelevant. By overriding this tree-shape consideration, it is possible to perform label merging in polynomial time. Based on how MPLS signaling works, this letter proposes an algorithm to compute the minimum number of labels using label merging: the Full Label Merging algorithm. As conclusion, we reclassify the Merging Problem as Polynomial-solvable, instead of NP-complete. In addition, simulation experiments confirm that without the tree-branch selection problem, more labels can be reduced

Aquest article presenta un estudi detallat de peces ceràmiques que pertanyen al tipus ceràmic conegut com derivada de la sigil·lata paleocristiana (D.S.P.), obrada al migdia de la Gàl·lia des de molt a final del segle IV fins ben entrat el VI i exportada per tota la costa de la Mediterrània occidental
