O desporto de natureza na oferta das empresas de animação turística na Madeira

Nas últimas décadas, assistiu-se a um grande crescimento das atividades de Desporto na Natureza associadas a um novo paradigma da prática desportiva, e ao desenvolvimento da indústria de Turismo e Lazer. Estas atividades, realizadas na natureza, dão resposta às exigências de um novo tipo de turista ativo e constituem um importante produto turístico oferecido aos visitantes da Madeira, onde as reservas marinhas ...

Memorable Tourism experience in the context of astrotourism

Astrotourism involves a variety of activities carried out during the night, requiring a deeper knowledge about the cognitive and emotional process that the tourist has and that leads to a memorable experience and loyalty. This study explores how (i) astrotourism stimuli are associated with cognitive states, designed by knowledge and involvement, (ii) cognitive states increase emotional states, represented by he...

Lipid metabolism in iron overloaded mice adipose tissue

Potential of omega-3 and conjugated fatty acids to control microglia inflammato...

High-fat diet-induced obesity detrimentally affects brain function by inducing chronic low-grade inflammation. This neuroinflammation is, at least in part, likely to be mediated by microglia, which are the main immune cell population in the brain. Microglia express a wide range of lipid-sensitive receptors and their activity can be modulated by fatty acids that cross the blood-brain barrier. Here, by combining ...

Parcel delivery services: A sectorization approach with simulation

Sectorization problems, also known as districting or territory design, deal with grouping a set of previously defined basic units, such as points or small geographical areas, into a fixed number of sectors or responsibility areas. Usually, there are multiple criteria to be satisfied regarding the geographic characteristics of the territory or the planning purposes. This work addresses a case study of parcel del...

Study on the influence of waves on coastal diffusion using image analysis

A series of novel image analysis techniques have been used to study surf-zone hydrodynamics taking advantage of recent advances in digital processing of images taken from video recordings of the sea surface near the coast. The use of image analysis allows the estimation of both spatial and temporal characteristics of wave fields, surface circulation and mixing in the surf zone. The dispersion of blobs of dye re...

A transparent dialogue between iconography and chemical characterisation: a set...

This work presents the first results of the iconographic study and analytical characterisation of a set of four stained-glass panels that are part of the collection of National Palace of Pena (Sintra, Portugal). These panels were collected by the King Ferdinand II in the mid-nineteenth century, for his main residence the Palace of Necessidades (Lisbon, Portugal), and only first presented to the general public i...

Developing a new simulation and visualization platform for researching aspects ...

Nowadays, mobile networks represent one of the most innovative and challenging technological and research-oriented fields of work. The growth on user subscriptions and the advances introduced by Artificial Intelligence (AI) and Internet of Things (IoT), greatly enhanced the complexity and potential of communication networks. The increase on variety of devices and exchanged mobile data traffic resulted in demand...

Root cause analysis of low throughput situations using boosting algorithms and ...

Detecting and diagnosing the root cause of failures in mobile networks is an increasingly demanding and time consuming task, given its technological growing complexity. This paper focuses on predicting and diagnosing low User Downlink (DL) Average Throughput situations, using supervised learning and the Tree Shapley Additive Explanations (SHAP) method. To fulfill this objective, Boosting classification models a...
