This article addresses the problem of obtaining reduced complexity models of multi-reach water delivery canals that are suitable for robust and linear parameter varying (LPV) control design. In the first stage, by applying a method known from the literature, a finite dimensional rational transfer function of a priori defined order is obtained for each canal reach by linearizing the Saint-Venant equations. Then, by using block diagrams algebra, these different models are combined with linearized gate models in order to obtain the overall canal model. In what concerns the control design objectives, this approach has the advantages of providing a model with prescribed order and to quantify the high frequency uncertainty due to model approximation. A case study with a 3-reach canal is presented, and the resulting model is compared with experimental data. © 2014 IEEE.

A Síndrome de Brown (SB) é uma síndrome anatómica e restritiva. Segundo Brown (1942), esta síndrome é classificada como uma ausência de elevação em adução, uma síndrome restritiva do grande oblíquo. Pode ser congénita, adquirida e iatrogénica e divide-se como ligeira, severa ou profunda. O Pequeno Oblíquo (PO) tem como acções a exciclodução, elevação e abdução. Ao estar afectado, observa-se nos movimentos oculares limitação da elevação e adução, que induz uma paralisia deste músculo. Assim, as duas apresentam ausência de elevação em adução, sendo importante, a realização de diagnóstico diferencial entre elas. Objectivos: Identificar as diversas características motoras e sensoriais da paralisia do PO comparando-as com as características da SB, especificando os testes de ortóptica adequados. Apresentar o diagnóstico diferencial a realizar, explicitando as características principais dos exames coordimétricos e do teste das ducções forçadas.

The interest of the study on the implementation of expanded agglomerated cork as exterior wall covering derives from two critical factors in a perspective of sustainable development: the use of a product consisting of a renewable natural material-cork-and the concern to contribute to greater sustainability in construction. The study aims to assess the feasibility of its use by analyzing the corresponding behaviour under different conditions. Since this application is relatively recent, only about ten years old, there is still much to learn about the reliability of its long-term properties. In this context, this study aims to deepen and approach aspects, some of them poorly studied and even unknown, that deal with characteristics that will make the agglomerate a good choice for exterior wall covering. The analysis of these and other characteristics is being performed by testing both under actual exposure conditions, on an experimental cell at LNEC, and on laboratory. In this paper the main laboratory tests are presented and the obtained results are compared with the outcome of the field study. © (2015) Trans Tech Publications, Switzerland.
