Tendency to adopt blockchain technology in Portuguese supply chains
Pereira, P. A.; Martins, A. L.; Ferreira, J. C.This paper aims to investigate the implementation potential of blockchain technology in supply chain management by Portuguese organizations, by perceiving their advantages, disadvantages, and barriers their familiarity with the concept and the adoption scenario.
Creation of museums as strategy for preservation of the fossil heritage of Arar...
Barreto, A. M. F.; Brilha, J. B.; Duque, R. R. C.; do Prado, L. C.; Pereira, P. A.; Araripe, R. C.; Carvalho, A. R. A.; Ghilardi, A. M.O Araripe pernambucano tem excelentes exposições de rochas da Formação Santana, Bacia Sedimentar do Araripe (PE, CE e PI), reconhecida internacionalmente pelos fósseis de vertebrados, preservados em concreções, considerados entre os mais importantes do supercontinente Gondwana (110 Ma). Embora a região tenha excelente potencial para coleta e estudos paleontológicos, facilitada pela extração a céu aberto da gips...
O caso português no projeto CLS
Almeida, A. M.; Costa, Manuel F. M.; Malheiro, Teresa; Pereira, P. A.; Silva, Mário Zamith; Varela, Paulo Idalino Balça; Marques, Marta Isabel BessaO projeto Creative Little Scientists (CLS) reuniu criatividade com ciência e matemática no ensino pré-escolar e nos primeiros anos do ensino básico (crianças até aos 8 anos de idade). Através do CLS foi possível obter uma imagem clara das práticas existentes, bem como as suas implicações, oportunidades e desafios. Com base nisso, o projeto propôs diretrizes, currículos e materiais exemplares para a formação de ...
Creative Little Scientists: enabling creativity through Science and Mathematics...
Costa, Manuel F. M.; Marques, Marta Isabel Bessa; Machado, P. J.; Almeida, Mário; Malheiro, Teresa; Pereira, P. A.The Country Report on in-depth field work in Portugal forms part of the Country Reports (Deliverable D4.3) of the EU-funded project Creative Little Scientists and aims at presenting the qualitative analysis of data gathered through field work in schools in Portugal.
Is it possible to assess spatial correlations in a system of polarizable partic...
Pereira, Rui M. S.; Pereira, P. A.; Smirnov, Georgi; Vasilevskiy, MikhailOptical response of a system of (nearly) identical polarizable particles, coupled by electromagnetic interactions is studied theoretically addressing the following question: Is it possible to extract information concerning the spatial correlations in the particles' positions from the experimentally measurable optical response of the system? The relation between the spectral-dependent solutions of the coupled-di...
New e-learning objects for the mathematics courses from engineering degrees : d...
Pereira, Rui M. S.; Brito, Irene; Machado, Gaspar J.; Malheiro, Teresa; Vaz, Estelita; Flores, Maria Assunção; Figueiredo, Jorge Manuel; Pereira, P. A.Mathematics at an undergraduate level is frequently presented to the students in quite a traditional way. When implementing the Bologna education reform in Portuguese universities, the number of contact hours of the courses decreased (considerably in some cases), therefore increasing the need of a more self-responsible learning by the student. This means that the student has to work by himself (i.e., outside le...

Um sistema de apoio à decisão baseado em optimização para o planeamento de auto...
Pereira, P. A.Neste trabalho apresentamos o processo de desenvolvimento e implementação de um sistema de apoio à decisão (SAD) para o planeamento do espaço de auto-promoção de uma estação de televisão portuguesa. As estações de televisão têm espaços temporais dedicados à promoção dos seus próprios produtos. Pretende-se que o conjunto semanal destes espaços seja utilizado de forma optimizada. Foram identicados objectivos espe...
A genetic algorithm approach for the TV self-promotion assignment problem
Pereira, P. A.; Fontes, Fernando A. C. C.; Fontes, Dalila B. M. M.We report on the development of a Genetic Algorithm (GA), which has been integrated into a Decision Support System to plan the best assignment of the weekly self-promotion space for a TV station. The problem addressed consists on deciding which shows to advertise and when such that the number of viewers, of an intended group or target, is maximized. The GA proposed incorporates a greedy heuristic to find good i...
A decision support system for planning promotion time slots
Pereira, P. A.; Fontes, Fernando A. C. C.; Fontes, Dalila B. M. M.We report on the development of a Decision Support System (DSS) to plan the best assignment for the weekly promotion space of a TV station. Each product to promote has a given target audience that is best reached at specific time periods during the week. The DSS aims to maximize the total viewing for each product within its target audience while fulfilling a set of constraints defined by the user. The purpose o...
