- Complexity-Aware High Efficiency Video CodingPublication . Corrêa, Guilherme; Assunção, Pedro; Agostini, Luciano; Cruz, Luis A. da SilvaThis book discusses computational complexity of High Efficiency Video Coding (HEVC) encoders with coverage extending from the analysis of HEVC compression efficiency and computational complexity to the reduction and scaling of its encoding complexity. After an introduction to the topic and a review of the state-of-the-art research in the field, the authors provide a detailed analysis of the HEVC encoding tools compression efficiency and computational complexity. Readers will benefit from a set of algorithms for scaling the computational complexity of HEVC encoders, all of which take advantage from the flexibility of the frame partitioning structures allowed by the standard. The authors also provide a set of early termination methods based on data mining and machine learning techniques, which are able to reduce the computational complexity required to find the best frame partitioning structures. The applicability of the proposed methods is finally exemplified with an encoding time control system that employs the best complexity reduction and scaling methods presented throughout the book. The methods presented in this book are especially useful in power-constrained, portable multimedia devices to reduce energy consumption and to extend battery life. They can also be applied to portable and non-portable multimedia devices operating in real time with limited computational resources.

- PrefacePublication . Dantas, José Guilherme Leitão; Carvalho, Luísa CagicaOver the last years we have witnessed the enormous success of quite demanding ventures all over the world. We are particularly talking about technology-based projects which, in some cases, have revolutionized the way we live. Their impact on the national and international level has been unequivocal concerning jobs and wealth creation, the new solutions their development have enabled, etc. That kind of ventures, regardless of their outstanding relevance, is the exception rather than the norm, i.e., they are only the visible tip of the iceberg, in that they only account for a very small percentage of the entrepreneurial activity. Nevertheless, they belong to the so-called mainstream entrepreneurship, are the dream of every economy, and deserve the attention of many researchers. (...) In short, the book starts by covering a set of activities upstream of the entrepreneurial activity, and then addresses a significant, though not exhaustive, set of different types of entrepreneurship, often paving the way for more in-depth investigations which will allow us to continue expanding such a relevant theme for our collective future.
- PrefacePublication . Moreira, António Carrizo; Dantas, José Guilherme LeitãoEntrepreneurship is far from being a novel concept. To find its roots we have to go back to the 18th century and to the original authors of the concept, namely Richard Cantillon and Jean-Baptiste Say. Nevertheless, despite the multiple authors who have successively addressed this issue over the many decades, entrepreneurship only earned “citizenship rights” in the economy from the 1970s/80s onwards, given the evidence that SMEs were critical regarding wealth and jobs creation, the reduction of regional asymmetries, and being more effective than larger firms in terms of innovation (particularly in the early stages of the innovation process).

- Atitudes e Comportamentos de Separação de Embalagens Usadas na Comunidade Intermunicipal da Região de LeiriaPublication . Fernandes, Maria Eduarda; Gomes da Silva, Carlos; Gaspar Ferreira, Alcina; Febra, Lígia; Maurício Costa, JoãoA Comunidade Intermunicipal da Região de Leiria (CIMRL) é composta por 10 Municípios, com cerca de 287 mil habitantes (INE, 2022) e recolhe anualmente 123 022 toneladas de resíduos sólidos urbanos, dos quais apenas 17% são recolhidos de forma seletiva (INE, 2025). Neste contexto, e enquadrado no Projeto Embalagem do Futuro (PPS08), é importante compreender melhor os comportamentos e atitudes dos agregados familiares da CIMRL face à separação de embalagens usadas (plástico, metal/alumínio, vidro, cartão/papel e cápsulas de café). Tendo por base a Theory of Planned Behavior, uma das principais teorias usadas para compreender a complexidade do comportamento social humano, as normas morais e os valores pro-ambientais, foi realizado um inquérito online junto dos agregados familiares da CIMRL.
