Os montes da serra de Tavira

The human occupation of the Tavira ridge is characterised by a network of small agglomerations of buildings (known as ‘montes’) belonging to the proprietors of lands around them. This way of organising places is, by and large, extensive to an important area of the schist mountains that stretch from Alentejo to Algarve, from the Guadiana river to the Atlantic Ocean. However, within the scope of that larger entity, the Tavira ridge appears as a sub-unit with traits of its own, which may be attributed not only to biophysical conditions, but also to the historical circumstances associated to the settlement of the territory. This particular ridge, which was confined to the perimeter of the Tavira municipality during the days of the Old Regime, has been more densely populated, due to its lack of interior hierarchisation, unlike what happens in neighbouring sub-units, both in terms of agglomeration sizes and of the property system itself. The traditional architecture of these areas was usually reduced to the bare essentials, reflecting the adverse conditions that generally surrounded the local economies. As can easily be gleaned from the plans shown here, the groupings of edifices that define the ridge’s settlement are largely characterised by the aggregation of buildings belonging to various owners, often intent on achieving a prominent position in the landscape.

Adaptive generalized predictive control algorithm implemented over an heterogeneous parallel architecture

In this paper a parallel implementation of an Adaprtive Generalized Predictive Control (AGPC) algorithm is presented. Since the AGPC algorithm needs to be fed with knowledge of the plant transfer function, the parallelization of a standard Recursive Least Squares (RLS) estimator and a GPC predictor is discussed here.

Enterprise architecture model: an approach proposition. A case study of information systems in the hospitality industry

This paper discusses the role of enterprise architecture representation, in the context of ERP (Enterprise Resource Planning) information systems, as an instrument for an organization to reflect on itself and develop its business strategies and respective alignment with Information Systems. The paper proposes a representation model of enterprise architecture, as a tool for recommending good practices, and it emerges from a case study undertaken in the context of and investigation on advantages and limitations of ERP systems in the hospitality industry. The proposed approach is also inspired on other academic or market propositions suitable for the objectives of the investigation. It consists on a set of items representing the steps that must be taken by top managers and IS managers.
