Distribution of OFDM radio signals over optical fiber
Paulo Andrade; Mário Lima; António TeixeiraIn this paper, we will study, via simulation, several transmission schemes of OFDM radio signals over optical fiber, in order to evaluate their main advantages and limitations. We will start by studying the transmission of 2 OFDM channels at 8GHz and 60 GHz, considering several types of optical modulation: Double Sideband (DSB), Vestigial Sideband (VSB) and Double Sideband-Carrier Suppressed (DSB-CS). Then, we ...

Retrieving Information in online dispute resolution platforms : a hybrid method
Carneiro, Davide; Novais, Paulo; Andrade, Francisco Carneiro Pacheco; Neves, JoséInformation Retrieval is a theme that is so multifaceted as it is its significance to any knowledge-based sphere of influence. This is true in The Law, especially when we judge under the angle of the so-called On-line Dispute Resolution. Indeed, there is the need to analyze and develop efficient information retrieval methods that may improve the course of actions that depend on such techniques. It was under th...
Mean intrasellar pressure, visual field, headache intensity and quality of life...
Pereira-Neto,Aldo; Borba,André Meireles; Mello,Paulo Andrade de; Naves,Luciana Ansanelli; Araújo Jr,Antônio Santos de; Casulari,Luis AugustoIntrasellar pressure (ISP) measurement technique has recently opened a new line of research in neuroendocrinology. The absolute and mean ISP values were investigated in 25 patients consecutively operated at the Brasilia University Hospital (DF). These data were correlated with serum prolactin levels, number of visual quadrant affected, tumor size, quality of life (measured through the SF-36 scale) and graded he...
Application of the Spielberger's State-Trait Anger Expression Inventory in clin...
Azevedo,Flávia Barros de; Wang,Yuan-Pang; Goulart,Alessandra Carvalho; Lotufo,Paulo Andrade; Benseñor,Isabela MartinsOBJECTIVE: To examine the factor structure of the Portuguese version of State-Trait Anger Expression Inventory (STAXI) in clinical patients. METHOD: 400 subjects from an internal medicine outpatient unit and 200 from a medical ward were recruited. Patients answered questions about clinical data, the STAXI, and the Beck Depression Inventory (BDI). Raw score of the STAXI was submitted to reliability assessment an...
Fodder salt fed to small ruminants
Oliveira,Gabriel Jorge Carneiro de; Jaeger,Soraya Maria Palma Luz; Bagaldo,Adriana Regina; Oliveira,Paulo Andrade deThe price of the products used for animal supplementation and the existence of a rich native flora of eudicotyledon forage, drove the idea for develop a technique feed supplementation aiming improve livestock yield levels in the semiarid zone. The fodder salt technique has been developed by the Tropical Zootechnical Rsearch Group at the Centro de Ciências Agrárias Ambientais e Biológicas da Universidade Federal...

Genetic algorithms approach for containerships fleet management dependent on ca...
Moura, Ana; Martins, Paulo; Andrade-Campos, António; Lobo,This work proposes a method to improve the flexibility of short sea shipping and to increase its competitiveness with other means of freight transport. A logistic model and a mathematical model are developed to manage a fleet of two or more vessels which transport cargo to and from several ports, bearing in mind the cargo distribution and delivery deadlines. At each port, the model determines which port to visi...
