Real-Time Tariffs for Electric Vehicles in Wind Power based Power Systems

The use of Electric Vehicles (EVs) will change significantly the planning and management of power systems in a near future. This paper proposes a real-time tariff strategy for the charge process of the EVs. The main objective is to evaluate the influence of real-time tariffs in the EVs owners’ behaviour and also the impact in load diagram. The paper proposes the energy price variation according to the relation between wind generation and power consumption. The proposed strategy was tested in two different days in the Danish power system. January 31st and August 13th 2013 were selected because of the high quantities of wind generation. The main goal is to evaluate the changes in the EVs charging diagram with the energy price preventing wind curtailment

This study is within the activities of Project “PrunusPós - Optimization of processes for the storage, cold conservation, active and/or intelligent packaging and food quality traceability in post-harvested fruit products”, project n.º PDR2020-101-031695, Partnership n.º 87, initiative n.º 175, promoted by PDR 2020 and co-funded by FEADER within Portugal 2020.This paper presents the current status and future trends of sensor technologies for food products traceability, specifically for systems devoted to be applied in the cold storage and refrigerated transport of horticultural products. The available monitoring technologies such as dataloggers, TTI, WSN, RFID, and combined approaches are evaluated and compared in terms of dimensions, sensor parameter (temperature, relative humidity, water vapor, ethylene and other gases released during the biological processes of fruit), robustness, reliability, energy autonomy, bandwidth (if applicable), connection, among others. The aim of the study consists in evaluating how these technologies can be successfully applied for traceability of horticultural products and are what the future trends in terms of technical and technological specifications that will guide the development of these systems. It is expected that the increasing use of these systems for food traceability increases food quality and safety, reducing food waste.info:eu-repo/semantics/publishedVersio

Energy consumption and energy efficiency measures in the Portuguese food processing industry

In the present study, simple energy surveys and audits were performed in 60 companies of the processing industry of meat, dairy, horticultural and bread and pastry products. 20 of the companies analyzed were located in the North region, 21 in the center region and 19 in the Alentejo region. The number of refrigeration chambers, the building infrastructure and the energy consumptions of the equipment used in the manufacturing processes were evaluated. This study allows to compare the energy consumption of the different manufacturing processes of regional food products. The aim of the study is to present several measures and best practices aimed for the improvement of the energy efficiency of the food sector as all. The implementation of simple and very cost-effective transversal electricity savings measures such as awareness and/or training of operators, proper maintenance and monitoring tasks, can benefit the sector. The tailored energy efficiency measures by sector are discussed. These energy efficient practice measures can offer savings on several levels, which may increase productivity and competitiveness and improve the environmental impact, and thus the global sustainability of the Portuguese food sector.info:eu-repo/semantics/publishedVersio

Data modeling for inter- and intra-individual stability of young swimmers’ performance: a longitudinal cluster analysis

The aims of this study were to classify, identify and follow-up young swimmers' performance and its biomechanical determinants during two competitive seasons (in seven different moments of assessment-M), and analyze the individual variations of each swimmer. Method: Thirty young swimmers (14 boys: 12.70 +/- 0.63 years-old; 16 girls: 11.72 +/- 0.71 years-old) were recruited. A set of anthropometric, kinematic, efficiency, hydrodynamic and mechanical power variables were assessed. Results: The cluster solution (i.e., number of ideal clusters for this sample) resulted in three clusters, which were named as: cluster 1 ("talented"), cluster 2 ("proficient"), and cluster 3 ("non-proficient"). The performance improved between moments of assessment in all clusters (cluster 1-M1: 68.07 +/- 6.62s vs M7: 61.46 +/- 3.43s; cluster 2-M1: 73.14 +/- 4.87s vs M7: 65.33 +/- 2.97s; cluster 3-M1: 82.60 +/- 4.18s vs M7: 70.09 +/- 3.48s). Anthropometric features also increased between moments of assessment, and remaining biomechanical variables (kinematic, efficiency, hydrodynamic and mechanical power) also increased between M1 and M7, in all clusters. Cluster 1 increased their swimmer's membership between M1 and M7 (4 to 11), cluster 2 decreased (12 to 5), and cluster 3 maintained (14). Conclusion: It can be concluded that the cluster formation depends on different determinant factors during two competitive seasons, and young swimmers are prone to change from one cluster to another over this period of timeThis project was supported by the National Funds through FCT - Portuguese Foundation for Science and Technology [UID/DTP/04045/2019], and the European Fund for regional development (FEDER) allocated by European Union through the COMPETE 2020 Programme [POCI-01-0145-FEDER-006969].info:eu-repo/semantics/publishedVersio

Young swimmers' anthropometrics, biomechanics, energetics, and efficiency as underlying performance factors: a systematic narrative review

Introduction: In youth swimming, researchers are interested in understanding how anthropometry and parameters related to swimming technique (biomechanics, energetics, and efficiency) influence the performance. However, there is not any review in the literature that consolidates the body of knowledge of this topic. The objective of this study was to review systematically the current body of work on the influence of determinant factors related to swimming technique (biomechanics, energetics, and efficiency) and anthropometry in the young performance of swimmers. Methods: The Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) guidelines were used to identify relevant studies. Results: After screening, 240 studies were analyzed and 59 related to swimming performance, and its determinant factors were retained for synthesis. Studies revealed a high-quality index by PEDro scale (mean score was 7.17 ± 1.40). Twenty-five studies were longitudinal designs and the remaining 34 cross-sectional designs. Most of the studies (N = 39, 66.1%) reported concurrently two or more determinant factors (anthropometrics, biomechanics, energetics, and efficiency). Conclusion: Youth swimming research relies on a multifactorial assessment. From the synthesis, it is possible to conclude that the performance of young swimmers is characterized by a multifactorial, holistic, and dynamic phenomenon. Better performance has always been related to better swimming technique and higher anthropometrics. This suggests that both anthropometrics (i.e., nature) and training (i.e., nurture) play key roles in the swimming performance of young swimmers.This work is supported by national funds (FCT—Portuguese Foundation for Science and Technology) under the project UIBD/DTP/04045/2020.info:eu-repo/semantics/publishedVersio

A relação entre o funcionamento familiar e a ego-resiliência infantil numa amostra de crianças entre os 10 e os 15 anos de idade e os seus respetivos cuidadores

Dissertação de Mestrado apresentada no ISPA – Instituto Universitário para obtenção de grau de Mestre na especialidade de Psicologia ClínicaIntrodução: A resiliência familiar consiste na capacidade das famílias para enfrentarem e ultrapassarem crises, surgindo com mais recursos após as mesmas (Walsh, 2016). A egoresiliência é uma característica de personalidade que permite a adaptação a stressores externos e internos (Block & Block, 1980). Estes construtos são interdependentes (Masten & Monn, 2015). Contudo, ainda não existem estudos suficientes que promovam uma integração entre ambos. Método: O presente estudo tem como objetivo validar e adaptar a Escala de Resiliência Familiar da Walsh e a Escala de Ego-resiliência Infantil para uma amostra de crianças e jovens entre os 10 e 15 anos de idade e os seus cuidadores, assim como explorar a relação entre o funcionamento familiar e a ego-resiliência infantil. A amostra foi constituída por 367 participantes, 230 cuidadores e 137 crianças e jovens que responderam a questões sociodemográficas e preencheram a versão portuguesa das escalas. Foram realizadas análises fatoriais confirmatórias para avaliar a validade fatorial. Averiguaram-se também a fiabilidade das escalas, a validade convergente e a validade discriminante. Foram realizadas regressões lineares para explorar o impacto do funcionamento familiar na ego-resiliência infantil. Resultados: As análises fatoriais confirmatórias não suportaram os modelos originais. O modelo final da Escala de Ego-resiliência Infantil apresentou índices de ajustamento aceitáveis e qualidades psicométricas sofríveis. O modelo final da Escala de Resiliência Familiar da Walsh apresentou índices de ajustamento sofríveis e boas qualidades psicométricas. O funcionamento familiar apresentou um impacto significativo na ego-resiliência infantil. Conclusão: Estes instrumentos consistem em ferramentas úteis que podem ser utilizadas em intervenções que promovam a resiliência.Introduction: The concept of family resilience refers to the capacity of a family as a functional system, impacted by highly stressful events, to positive adaptation and strengthening the family unit (Walsh, 2016). Ego-resiliency enables individuals to adapt to environmental demands (Block & Block, 1980). Resilience in individuals interplay with family resilience, yet there remains considerable work to do on the processes that link child both concepts (Masten & Monn, 2015). Method: The present study aims to translate and evaluate the psychometric properties of a portuguese version of the Walsh Family Resilience Questionnaire and the Ego-resiliency Qsort, and evaluate the impact of the familiar functioning on children’s psychological adjustment in a portuguese sample with children and adolescences between 10 and 15 years old and their caregivers. A sample of 230 caregivers and 137 children and adolescences provided sociodemographic information and completed a portuguese version of the questionnaires. Confirmatory Factor Analyses were performed to evaluate the questionnaires structures, as well as the internal consistency, composite reliability, convergent-related and discriminant-related validity. Linear regressions were performed to explore the impact of the familiar functioning on children’s psychological adjustment. Results: Factorial Analysis didn´t supported originals solutions for the questionnaires. The new solution for the Ego-resiliency Q-sort revealed acceptable goodness of fit and poor psychometric properties. The new solution for Walsh Questionnaire revealed a poor goodness of fit and good psychometric properties. Family functioning revealed significant impact on children’s psychological adjustment. Conclusion: The questionnaires represent a good tool that can be used in interventions for enhancing psychological well-being

Intervenção sobre o Património do Século XX. Caso de estudo: Casa Beires de Álvaro Siza

Num momento em que se levantam questões quanto à perenidade da produção de Álvaro Siza e, tendo o próprio arquitecto tomado medidas quanto à protecção do seu arquivo, a presente Dissertação aborda o tema da Reabilitação do Património recente, utilizando como caso de estudo a Casa Beires do Arquitecto Siza.Como meio de formar uma abordagem crítica e consciente à intervenção sobre uma obra de valor patrimonial e arquitectónico, foi necessário perceber a evolução da prática da Conservação, do Restauro e da Reabilitação, formas mais comuns de operação sobre o construído, nos séculos XIX e XX foram repletos de confrontos de interpretações sobre os valores do património e da autenticidade, e consequentemente diferentes critérios para a sua salvaguarda.Organizações como a Do.Co.Mo.Mo. ou o ISC20C da ICOMOS dinamizaram esta discussão, no final do século XX, internacionalizando-a, promovendo a via da documentação e inventariação como base de uma possível salvaguarda da arquitectura Moderna.O reconhecimento da multiplicidade de valores do Moderno e da sua natureza, diversa e relativa, enquadram-se numa discussão mais generalizada, a da Autenticidade, alvo de duas conferências internacionais, de onde resultou o Documento de Nara sobre a Autenticidade. O termo agora discutido, embora não totalmente esclarecido, implica o estudo sobre as práticas que envolvem a produção do património, as culturas, os saberes, ultrapassando a dimensão material ou da imagem para se apoiar na antropologia.Enquadrada a obra de Siza no desenrolar da segunda metade do século, peça indispensável para a formação da 'Escola do Porto', a abordagem à Casa Beires exige o estudo da sua documentação disponível, o levantamento arquitectónico da obra, a análise às patologias que apresenta, e a reflexão sobre a profundidade de uma possível intervenção.As questions of the perpetualness of Álvaro Siza's work are being raised and, having measures been taken about the protection of his archives, the following thesis addresses the Rehabilitation of recent Heritage, approaching it through the study of the Beires House, by Álvaro Siza.As a means to form a critical and conscious approach to the intervention on a piece of architectural and heritage value, it was necessary to understand the evolution of the Conservation, Restoration and Rehabilitation's practice through the times. The XIX and XXth centuries are particularly filled with confrontations and interpretations of the values of heritage and authenticity and hence, the different criteria of its safeguard.Organizations as Do.Co.Mo.Mo. and ISC20C have moved this discussion in the late XXth century, promoting the documentation and inventory of Modern Architecture as a basis for its possible protection.The acknowledgement of Modern's multiplicity of values and their nature frames a more general discussion, Authenticity, object of study at two international meetings, having resulted from the latter the Nara Document on Authenticity. The term, now in discussion although not thoroughly clarified, implies the study of the practices that inform the production of Heritage, as local cultures and knowledge, overcoming the material or visual character and leaning on Anthropology.After framing Siza's work in the outcome of the second half of the XXth century, imperative to the birth of the 'Oporto School', the approach to the Beires House implies the study of available documentation, its architectural measurement, the analysis of its current state and a deliberation on the depth of a possible intervention

Quantificação de cargas poluentes afluentes a um rio temporário de características mediterrânicas no sul de Portugal: caso estudo da bacia do rio Pardiela

Os sistemas aquáticos temporários são frequentes na região Mediterrânica assim como em regiões semi-aridas. São definidos como sistemas que durante um determinado período do ano não apresentam caudal superficial. Relativamente à estrutura e ao funcionamento destes sistemas, é obvio que tanto as comunidades terrestres como as aquáticas estão sujeitas a condições hidrológicas extremas, onde as características abióticas interagem em diferentes escalas. Compreender e prever as complexas interacções entre a hidrologia, os processos ecológicos e a biodiversidade, constitui a base para uma gestão sustentável em todo o mundo. Nos rios temporários as enxurradas depois do período seco produzem uma ressuspensão e transporte dos poluentes acumulados durante a estação seca. Estas condições particulares requerem práticas adaptadas à realidade (ex. agricultura, industria) para promover uma melhoria da qualidade integral dos ecossistemas. Torna-se pois urgente perceber o efeito destes eventos extremos através da quantificação das cargas afluentes às linhas de água. Com este objectivo, durante os últimos 6 anos, tem sido estudada uma bacia de características temporárias mediterrânicas situada no sul de Portugal; a bacia do Pardiela (Rio Guadiana). Têm-se pretendido estudar a integração de diferentes componentes do sistema (i.e. clima, morfologia e hidrologia) por forma a propor estratégias de conservação e reabilitação que auxiliem os parceiros aplicados (entidades com responsabilidade na gestão) através do fornecimento de ferramentas para uma gestão sustentável. Os resultados apresentados incluem a quantificação de cargas de Nitrogénio, Fósforo e Sólidos Suspensos, afluentes a um troço de terceira ordem no curso principal do rio Pardiela. Apresentam-se e discutem-se as respectivas evoluções anuais, destacando-se as situações de enxurrada que representam uma entrada muito significativa de Fósforo Total e de Sólidos Suspensos no sistema aquático. Conclui-se que nos rios temporários, os sistemas de gestão devem ser planeados à escala da bacia de forma a preservar a dinâmica natural do sistema. Permite-se assim identificar os factores que controlam cada sistema, tais como a hidrológico, as descargas urbanas, a ocupação de solo, as práticas agrícolas e a vegetação ripícola e compreender a sua variabilidade em função do regime hidrológico destes rios
