Nowadays there are a vast number of devices and technologies available for the common citizen to
improve their communication with others. This fosters the design and implementation of systems that explore
the available features of these devices. This paper presents a system that allows to inform, on a personalized
way, the actors of an education institution on a free way using popular communication standards. Features like
the system’s architecture, prototype and system’s evaluation are explained in the paper. Results show that this
system can be an important complement to other popular systems in education environments (e.g. e-mail, chats,
Wikis, forums, e-learning platforms etc.).
Based on the dyes and dyeing processes of an ancient embroidery of Castelo Branco this study reports a project with STS orientation.
Olive tree wood is an agricultural residue largely available in Portugal. It is estimated that the amount of material annually produced from olive trees pruning, can be up to 250 000 tonnes.
This wood resulting from pruning is a material rich in cellulose and hemicelluloses which can be recovered for the production of 2nd generation ethanol through its use as feedstock. Pretreatment is a crucial step in bioconversion of lignocellulosics to bioethanol, in order to improve the carbohydrates accessibility to enzymatic attack.
In the present work, the optimization of dilute acid pretreatment conditions of olive tree pruning was studied.

This paper presents the results of a research work on the evaluation of the compressive strength at high temperatures of a concrete made with recycled tire steel and textile fibers. It was considered five different concrete compositions, with a water/cement ratio (W/C = 0.43), differ only in the type and amount of fibers. The compositions with smaller amounts of textile fibers were those that gave better results. The compositions with steel fibers showed a less explosive rupture showing the effectiveness of this type of fibers in the spalling and cracking control.

Background
Developing new assistive technologies is a challenge for an ageing society and a possible response to the needs of older people in the care process and a challenge to promote autonomous living. The interaction between elderly and robots may depend on the choice of activities that robots can developed and the how important it is for older people. Social Assistive Robots can contribute to a positive impact in elderly well-being and active ageing.
Methods
31 elderly residents (10 men and 21 women) in a Portuguese nursing home were interviewed about their routines and interests. They were also assessed during 6 weeks, to evaluate interactions and activities initiative and involvement, using an scale adapted by authors from a Bertram and Pascal scale. This assessment was made by direct observation. The professionals and the director in the nursing home were also interviewed.
Research results
The adopted methodology allowed to identify the needs and interests of the elderly, and to classify the participants on the levels of social interactions, initiative and involvement in activities and social participation.
Conclusions
Some social, cognitive and physical activities were selected to be developed by a socially assisted robot and the evaluation process used in this research methodology will be used to evaluate the results of the intervention with a robot in social assistive domains, developed in a European Project INTERREG (EUROAGE).
Abstract: Emerging economies are in an almost winless situation: they would benefit from improving
the extremely poor economic situation, making them self-reliant and economically productive.
However, the poor fight for daily survival and, therefore, cannot afford to improve themselves. This
article describes the state of the “Grande Hotel” in the city of Beira, Mozambique, built-in Portuguese
colonial times, a real vertical shanty building that is occupied by approximately 1000 inhabitants
trapped in poverty. To carry out any constructive intervention in a building or an urban complex,
it is necessary to carry out a rehabilitation project that is developed based on a diagnosis of the
building understudy, its main deteriorations, the causes, mechanisms of action, evolution, and
possible treatments to be used for its repair. Analysis methods are necessary for the conservation
of buildings since trying to stop, or correct buildings’ deterioration without a diagnosis of their
problems or a prognosis on their evolution is a risky procedure with a high percentage of failure
chances. The use of an appropriate methodology for diagnosing the damage present in the “Grande
Hotel” and its prediction of evolution and development should directly impact a better quality of
rehabilitation projects in the neighborhood where the building is located.
The relevance in the study of interaction between elderly and robots may depend on the choice of activities that robots can be developed to perform and the assessment of their impact and importance for older people. This research requires coordinated research between computer engineers and specialists in the humanities and social sciences. Being a recent research area, it is particularly relevant to carefully select the behavioural variables to be analyzed, the methodology adopted and the instruments that allow for a rigorous evaluation. Based on these assumptions, the present study aims to develop Innovative Initiatives for the Promotion of Active Aging in the EUROACE Region. The authors propose an appropriate methodology and instruments to evaluate the impact of the human-robot interaction in the promotion of a more active aging in a group of elderly in a nursing home. The analyzed variables focus on the involvement of the elderly in the activities, their capacity for initiative and to establish social interactions, indicators of well-being and a proactive attitude. The methodology of the study is mixed (qualitative and quantitative), organized as an exploratory case study. Data collection is based on naturalistic observation but variables are quantitatively assessed in a pre/post-test design. The research design identified the narratives of the elderly and the staff of the institution regarding the needs and interests of each elderly person, classified the participants according to the levels of prevailing social interactions, involvement and initiative in activities, considered important variables for an active ageing and, in this sense, demonstrated its adequacy to be used to evaluate the results of the intervention using social assistive robots.

There is currently a high demand for professionals with digital skills in the areas of Information and Communication Technologies. As such, in future this trend is expected to increase. Higher education institutions are unable to train adequate numbers of qualified people to respond to employers' requests. In other areas, it is expected that increasing computerization and automation will have a significant impact on reducing certain types of jobs, which highlights the need and importance for many workers to develop new digital skills in order to be better prepared to face future challenges. It also seems clear that many of the needs may be met by people who, while not having a higher education in ICT fields, such as that taught in higher education institutions, these can be suppressed by people with specific training which is more focused on a particular technology or focused on certain development niches. In this context, low-code development platforms can play an important role in training or retraining people from areas with lower market demand for ICT areas. Their characteristics and potential make them suitable for technicians with higher qualifications in other areas, and other professionals, to acquire new skills through retraining or supplementing / recycling pre-acquired basic knowledge that may become productive labour in the IT world.
In this paper we describe a strategy, and several case studies, where a low-code development platform is used to reskill STEM professionals and/or professionals who, having basic IT knowledge are in precarious activities, to perform ICT professional activity. This strategy not only contributes to the needs of IT professionals but also enables many professionals to make timely retraining into areas of greater competitiveness, greater job stability and better working conditions. Throughout the paper, we present case studies that are part of this strategy and that have had positive results. These case studies include Enterprise-Higher Education collaborative training, reskilling for unemployed people with higher education in other areas, and training for those who are active, working in areas where labour needs are likely to decrease in the mid-term. The paper also identifies the benefits and contributions resulting from the use of the OutSystems low-code platform to implement this strategy.
Recovering old urban centres is a Portuguese strategy to promote development and economic
growth, supported by the strong evolution in the tourism sector that has been revealed as a key
element for increasing gross domestic product (GPB). The Europe has also a specific worry in which
built environment is concerned, namely through the European goals until 2020 that are based on the
need to reduce the energetic consume and to increase the use of renewable resources.
Having in mind these aspects, in this paper the following tasks were done: i) sustainable assessment
tools for rehabilitation actions were analysed; ii) European and national policies for urban
rehabilitation and renewal were studied, in deeper sense, the one towards sustainability; iii) to create
a simplified model to assess sustainability in old city centres interventions, criteria were defined;
iv) a model was designed with areas, criteria and assessment indicators. The model presented is
accurate with the built environment and its application makes possible to assess the impact of
solutions, systems and techniques adopted in the design process, with the analysis of the defined
criteria and the aim of improving the environmental, social and economic performances of buildings
and old urban centres.
The study of imagery has been a central pillar in the Sports Psychology field, since athletes have reported the use of imagery techniques in order to mentally practice body movements and, therefore, improve the actual physical performance. Similarly, music plays a quintessential role in many sports as its influence on athletes’ motivation, concentration, confidence and anxiety levels before and during the sporting practice has been widely reported and studied. The application of imagery and music combined has been reported to yield improvement in sporting performance. As a possible explanation, certain types of music have been considered as an element that decreases arousal levels in subjects, promoting a more effective use of imagery prior to performance. However, it has also been reported that subjects had better performance at tasks that assessed mental imagery processes after arousal increase after subjects’ exposure to arousing music. Thus, this study has investigated whether two distinct musical stimuli (simple and complex music) affected arousal levels in participants, and consequently the performance in a mental imagery of body parts (henceforth: motor imagery) cognitive task, namely mental-rotation of bodily-related pictures. 30 Sports Science students completed this mental rotation of body pictures task after exposure to three different stimuli (silence, complex music and simple music). Although results showed arousal levels decrease after subjects were exposed to both complex music and silence, this decrease did not yield any effect on performance, casting doubt on the hypothesis that arousal decrease facilitates motor imagery processes.
The lifelong learning paradigm has become a global phenomenon, having an influence on the political organization of various countries. The aim of this study was to map lifelong learning activities for the older people so to understand how this paradigm has been incorporated into practical actions. The scoping review method was chosen and the literature search was con ducted across five databases (Web of Science, Scopus, AgeLine, ERIC and MedLine) in English and between the years of 1972 and 2020. All peer reviewed papers which presented the conceptual notion of lifelong learning as a central topic to the study, the target audience of older men and women (50+ years old) and which described formal, non-formal and informal educational activities, were included in the present research. A total of 2,083 records were found, of which 309 were selected for the full reading screen ing; this, in turn, resulted in 38 records included. Most of these studies were published in the last decade (66%), originating in North America (36%) and adopting a qualitative methodological approach (81%). The lifelong learning activities for older people were noticeably more frequent in the non-formal
modality (60%), within a university context (46%) and from the perspective of the third generation of the concept (60%). It was concluded that there is an imbalance between lifelong learning activities for the older adults in the formal, non-formal and informal modalities and that the lifelong learning paradigm has been incorporated into practical actions by different concep tual generations.

Hydrological signatures are indices that help to describe the behavior of catchments. These indices can also be used to transfer information from gauged to ungauged catchments. In this study, different approaches were evaluated to determine volumetric runoff coefficients in 18 small/medium experimental gauged catchments of the Iberian Peninsula and to fit runoff calculations based on precipitation data for gauged and ungauged catchments. Using data derived from 1962 events, rainfall-runoff relationships were characterized and compared in order to evaluate the various hydrological response patterns. Volumetric runoff coefficients and cumulative runoff and precipitation ratios of the events that generated runoff (Rcum) minimized the root mean square error. A linear fit for the estimation of Rcum in ungauged catchments was based on mean annual precipitation, rates of infiltration, the fraction of forest-land use, and the catchment channel length. Despite high catchment heterogeneity, Rcum resulted in a suitable parameter to evaluate hydrological variability in rural gauged and ungauged catchments. In 50% of the catchments, the precipitation
accounted for less than 50% of the runoff variation. Annual precipitation, antecedent rainfall, and base flow did not have a high significance in rainfall-runoff relationships, which illustrates the heterogeneity of hydrological responses. Our results highlight the need for signature characterizations of small/medium rural catchments because they are the sources of runoff and sediment discharge into rivers, and it is more economical and efficient to take action to mitigate runoff in rural locations.
It is generally agreed that the choice of the most suitable uses based in soil and climatic factors, complemented with socio-economic criteria, promotes sustainable use of rural land. There are, however, different methodologies for defining the soil suitability to agroforestal systems or natural and seminatural ecosystems, including agricultural uses, forest plantations, agro-forestry areas and priority areas for nature conservation. Many of these methods rely on decision support systems based on multicriteria spatial analysis. In this study we intended to determine the different levels of suitability for agro-forestry use in a subregion located in the center of Portugal, near the border with Spain. To the effect we used a set of soil and topographic variables. The legal constraints and land cover were also included. The suitability evaluation was performed using the Analytic Hierarchy Process (AHP). A spatial analysis was also performed in order to confront the land use matrix with the soil potentiality. This analysis allows to identify areas where the use and management it is in accordance with their suitability, as well as areas where the use must be subject to a conversion or at least to a change of management mode.

The land use and land cover pattern of landscapes are key elements of basic landscape structure; accordingly, his pattern has an important role in landscape management, nature conservation and preservation. In the other hand the human impact on the ecological environment has attracted a significant amount of attention. In this study, hemeroby index (HI) was used to quantify the degree of human disturbance, and the relationship between HI and
landscape pattern metrics was explored in a region of Central Portugal. The main objectives of this study were to analyze the temporal and spatial characteristics of landscape pattern, and its relationship with different degrees of human disturbance. The Spearman’s correlations were determined to reveal the statistical connections between the landscape metric parameters and the HI values. At a landscape level the Mean Perimeter-Area Ratio (MPAR) showed a significant statistical connection with the HI. At a class level most of the metrics can be used to estimate the spatial changes of the hemeroby level, with Mean Patch Size (MPS) and Mean Perimeter-Area Ratio (MPAR) showing significant statistical connection with the hemeroby index, for agricultural areas, pastures and seminatural areas.
This paper presents a target-specific programming
language (TSL) that was designed to improve the design cycle of
code generation for an industrial embedded system. The native
assembly code, the new language structure and their constructs, are
presented in the paper. The proposed TSL is expressed using words
and terms that are related to the target’s domain and consequently it
is now easier to program, understand and to validate the desired code.
It is also demonstrated the language efficiency by comparing some
code described using the new language against the previous used
code. The design cycle is improved with the usage of the TSL
because description time and debug time are significantly reduced
with this new software tool. This is also a case of university-industry
partnership.

La importancia de las colectividades ha sido siempre crucial
para el avance cultural de cualquier país. En el caso de Hungría y de la
escindida Checoslovaquia, dichas agrupaciones fueron el motor de las
vanguardias sucedidas en ambos países, y desde el punto de vista
arquitectónico, también se convir��eron en los núcleos de pensamiento
desde los que el Movimiento Moderno penetró. En estas dos naciones
centroeuropeas, ambos colectivos se agruparon alrededor de una serie de
publicaciones como Devětsil en Checosolvaquia o Ma en Hungría,
convirtiéndose sus directores en estandartes de sus respectivas
vanguardias. La irrupción de las nuevas ideas imperantes en otros países,
rupturistas con la tradición, fueron asimiladas y adaptadas dando lugar al
funcionalismo checo por un lado y al constructivismo húngaro por otro, y
suponiendo uno de los mayores cambios, tanto desde el punto de vista
cultural como desde el arquitectónico, allí ocurridos.

A compressão medular maligna é uma emergência oncológica grave e frequente que requer um imediato reconhecimento e tratamento para alívio da dor e preservação das funções neurológicas. A falha no diagnóstico correcto conjuntamente com um limitado conhecimento do necessário referenciamento para tratamento imediato traduz-se numa paralisia completa e na maioria dos casos irreversível, já que 90% dos doentes ambulatórios podem permanecer ambulatórios se agirmos prontamente. Sem terapêutica, a compressão medular maligna é fonte de uma significativa morbilidade e mortalidade, dor severa, paralisia, incontinência e um decréscimo da qualidade de vida.

Obstructive sleep apnea is a respiratory problem that has serious consequences for physical and mental health, but also in monetary terms, since traffic accidents and poor work performance, among other direct consequences, are attributed to it. It is estimated that between 9% and 38% of the world’s population has this disease. This is a multifactorial disease, therefore, there are several methods of detection and treatment; however, all of them cause discomfort to the patient, or to those around them. In this article we propose a system for the detection and control of obstructive sleep apnea that promises to overcome the drawbacks of the existing therapies, therefore, potentially making it a practical and effective solution for this disease. The proof of concept presented in this paper makes use of an electromyography sensor to collect the myoelectric signal produced by the genioglossus muscle. Surface electrodes provide the electromyography signals to an ESP32 microcontroller, which has the function of analyzing and comparing the data obtained with a predefined value of the apnea threshold. After the detection of an apnea, the circuit is able to create a stimulus signal that is applied directly to the muscle, so that airway occlusion does not occur, and the user does not wake up. The data from each use are automatically sent to a database to be viewed and analyzed at a later point.
A procura de bens alimentares que garantam ao consumidor segurança alimentar tem sido um dos grandes pilares da expansão da área de produção agrícola seguindo os princípios e objectivos da Produção Integrada.
Em Abril de 2003, foi instalado um ensaio de pessegueiros em vasos, da cultivar Springcrest uma cultivar temporã e medianamente susceptível ao cancro causado por Phomopsis amygdali.
Foi realizado um plano de fertilização que compreendeu 4 modalidades de fertilização azotada, N0 sem fertilização, NI com nível insuficiente, N2 com nível considerado suficiente e N3 com nível excessivo.
Em Novembro de 2003 procedeu-se à inoculação das plantas com P. amygdali.
A avaliação da susceptibilidade foi quantificada através da medição da área de cancro desenvolvido nos locais da infecção, realizada entre Janeiro e Março de 2004.
Os resultados alcançados permitem concluir que há um efeito da fertilização azotada quer ao nível do vigor das plantas, quer ao nível da produção e da susceptibilidade ao cancro, verificando-se maior susceptibilidade na testemunha que não difere significativamente da modalidade N3.
A multidisciplinary, long term project aimed at developing and testing assessment and evaluation tools for the ecological management of the landscape is being developed in the University of Évora (Portugal). The main project is divided in three sub-projects (Characterization of the conservation value of the SE Alentejo Region; Identification of the main ecological processes and functions in Évora; and Analysis of the significance of ecological characterization methods in Apostiça). The main objectives to be achieved are to describe the ecological potential of the landscape, and determine the land-use practices and land-use intensities necessary to ensure the maintenance and promotion of the conservation value of landscape, in order to assess the ecological value of a land-use structure and also evaluate the sustainability of alternative land-use patterns. As preliminary conclusions we could say that the evaluation of the stability of a landscape by comparing the degree of correspondence of the nature of both levels of characterization - land-use distribution and homogeneous landscape units - is of particular importance in the evaluation of the fragmentation degree of that landscape, and the real disturbance determined by proposed land-use changes.
Following the recent trends in software engineering regarding the growing adoption of agile methodologies and low-code development platforms, and considering the results of surveys, we carried out on students, alumni and some IT companies, we adapted the software engineering teaching of a computer engineering course to the needs and new trends of the IT industry. The Scrum methodology and the OutSystems low-code development platform were used in a project-based learning approach for teaching agile software engineering practices. This approach was complemented with the presentation and discussion of several topics during the theoretical classes, lectures given by professionals from IT companies and study visits to an IT company that uses agile methodologies and low-code platforms. This approach aims to enhance the technical skills, namely development skills on a widely used low-code platform and other software engineering skills, but also to reinforce some non-technical skills of students like teamwork and communication, today highly valued by IT companies. The first results are quite positive.
Wireless Body Sensors for medical purposes offer valuable contributions to improve patients’ healthcare, including diagnosis and/or therapeutics monitoring. Body temperature is a crucial parameter in healthcare diagnosis. In gynecology and obstetrics it is measured at the skin’s surface, which is very influenced by the environment. This paper proposes a new intra-body sensor for long-term intra-vaginal temperature collection. The embedded IEEE 802.15.4 communication module allows the integration of this sensor in a Wireless Sensor Network (WSN) for remote data access and monitoring. We present the sensor architecture, the construction of the corresponding testbed, and its performance evaluation. This sensor may be used in different medical applications, including preterm labor prevention and fertility and ovulation period detection. The features of the constructed testbed were validated in laboratory tests verifying its accuracy and performance.
Recently, Google launched the Android mobile operating system
and several mobile devices already support it. This paper
proposes a mobile Android-enabled tool for collecting,
monitoring, and analyzing intra-vaginal temperature. A previous
proposed intra-vaginal sensor acquires temperature values and
sends the collected data to Android device over a Bluetooth
connection. The Android tool allows women for real-time
monitoring of their temperature with mobility support and
following their daily life. Woman can control and detect their
fertile and ovulation periods when this human parameter
increases about 0.5ºC over their regular temperature. Other
application of this solution includes the preterm labor
prevention. The proposed system was evaluated and validated,
and it is ready for use.
This paper presents some project themes
proposed by the authors and the methodology adopted in its supervision, in a transdisciplinary approach. We describe the projects and discuss the most relevant
aspects of this approach, from the technical and pedagogical points of view. The stronger points of this methodology are some similarities with the
environment that recent graduated students might find
in the employment market. Balancing the pros and
cons we conclude that due to the project
interdependencies, benefits are mainly on technical
skills improvement and in mutual responsibilities to
accomplish tasks on schedule.
Plasticity induced crack closure (PICC) is closely linked to the monotonic and reversed plastic deformation occurring at
the crack tip. The objective of the paper is to identify the different physical and numerical parameters affecting PICC,
and develop a sensitivity analysis to quantify their relative importance. The main parameters affecting PICC are the
load parameters, the yield stress, the size of finite elements and the numerical parameter considered to quantify PICC.
The numerical predictions should be independent of numerical parameters, therefore further work is required to
optimize the numerical models
For conventional cyclic-prefix (CP)-assisted block transmission systems, the CP length is selected on the basis of the expected maximum delay spread. With regard to single-carrier (SC)-based block transmission implementations, a full-length CP
is recommendable, since it allows good performances through the
use of simple frequency-domain equalization (FDE) techniques.
In this letter, a soft-decision-directed correction (SDDC)-aided
turbo FDE technique is presented for reduced-CP SC-based block
transmission systems using conventional frame structures. The
relations with some already known iterative FDE techniques are
established, and a set of performance results is reported and discussed.
The advantages of the proposed approach are emphasized,
namely, the possibility of approximately achieving (besides the
obvious bandwidth efficiency gain) the maximum power efficiency
gain that a strong CP reduction allows.
Tourism is characterized as being a sector that stands out as one of the business activities with the greatest potential for worldwide expansion, and as an engine for economic growth. If at the national level, the appeal of tourism is significant, on the local level this sector presents itself as an essential tool in regional development, as a means to avoid regional desertification and stagnation, stimulating the potential of more undeveloped regions. In such a competitive sector as tourism, companies should develop synergies and achieve competitive advantage. In this context, public-private partnerships play an important role in regional development. The aim of this paper is to present a theoretical context that combines different concepts and elements to explain and understand the public-private partnership phenomenon in tourism.
A conceptual model of the role of public-private partnerships will be proposed in order to contribute to successful regional development.

A intervenção no campo cultural a nível municipal em Portugal é, ainda, uma atividade em estruturação, com uma significativa dimensão experimentalista, a que, não raras vezes, está associado um défice de reflexão teórica e analítica. Neste artigo, sustenta-se que as políticas culturais autárquicas devem revestir um claro figurino territorialista, ou endógeno, porque só assim poderão constituir-se como verdadeiros instrumentos de valorização dos ativos locais e de qualificação das comunidades. Face a alguns dos mais pertinentes desafios existentes no contexto português de desenvolvimento local, serão enunciados dez princípios orientadores básicos a que uma política cultural municipal, de matriz endógena, precisa de responder eficazmente, bem como as principais características que lhe devem transmitir forma e conteúdo.

This work focuses on developed a decision support system based on multicriteria spatial analysis to assess the potential for generation of biomass residues from forestry sources in a region of Portugal (Beira Baixa). A set of environmental, economic and social criteria was defined, evaluated and weighted in the context of Saaty's analytic hierarchies. The best alternatives were obtained after applying Analytic Hierarchy Process (AHP). The model was applied to the central region of Portugal where forest and agriculture are the most representative land uses. Finally, sensitivity analysis of the set of factors and their associated weights was performed to test the robustness of the model. The proposed evaluation model provides a valuable reference for decision makers in establishing a standardized means of selecting the optimal location for new biomass plants.
This chapter examines the competitiveness footprints of SMEs within a high-tech cluster. A mixed methodology combining quantitative and qualitative data is used. More specifically, a case study is offered to show trends in innovative and entrepreneurial collaboration associated with an internationally competitive high-tech cluster. The findings shed light on the importance of collective efficiency strategies, with a focus on RD&I, implemented by SMEs that operate in an international and competitive market. This chapter highlights the lessons learned in two specific aspects: the role of innovation in the competitiveness of SMEs and the role of innovation and entrepreneurship networks in enhancing the functions of a high-technology industrial cluster, the Portuguese Engineering and Tooling Cluster.
Within the next decades, robots will need to be able to execute a large variety of tasks autonomously in a large variety of environments. To relax the resulting programming effort, a knowledge-enabled approach to robot programming can be adopted to organize information in re-usable knowledge pieces. However, for the ease of reuse, there needs to be an agreement on the meaning of terms. A common approach is to represent these terms using ontology languages that conceptualize the respective domain. In this work, we will review projects that use ontologies to support robot autonomy. We will systematically search for projects that fulfill a set of inclusion criteria and compare them with each other with respect to the scope of their ontology, what types of cognitive capabilities are supported by the use of ontologies, and which is their application domain.

his experimental study focuses on the comparison between two different sensors for vibration signals: a magnetoresistive sensor and an accelerometer as a calibrated reference. The vibrations are collected from a variable speed inductor motor setup, coupled to a ball bearing load with adjustable misalignments. To evaluate the performance of the magnetoresistive sensor against the accelerometer, several vibration measurements are performed in three different axes: axial, horizontal and vertical. Vibration velocity measurements from both sensors were collected and analyzed based on spectral decomposition of the signals. The high cross-correlation coefficient between spectrum vibration signatures in all experimental measurements shows good agreement between the proposed magnetoresistive sensor and the reference accelerometer performances. The results demonstrate the potential of this type of innovative and non-contact approach to vibration data collection and a prospective use of magnetoresistive sensors for predictive maintenance models for inductive motors in Industry 4.0 applications.
This paper aims to present a paradigm regarding the circular economy (CE) concept's communication, referring to the difficulty presented by the type of reflexivity involved in the circular economy process. We conduct an exploratory study methodology intended “to develop pertinent hypotheses and propositions for further inquiry, a study developed in the context of the project, Program INTERREG V-A Spain-Portugal (POCTEP) 2014–2020, REiNOVA_SI (Re-industrialization of the agri-food sector - Sustainability and Innovation) is a transnational cooperation project between Portugal and Spain which aims to promote the use of circular economy practices in agri-food micro-enterprises and SMEs. The paper draws the hypothesis, in Design thinking context, that gamification can induce a reflexivity thinking on CE, specifically on Agrofood entrepreneurs in the Portuguese context. Reflexivity could empower the connection between the company and its local context and stakeholders dissuading the drivers for abroad markets positioning.
The idea of monitoring several types of parameters in various environments has been motivating significant research works in Internet of Things (IoT). This paper presents the design and construction of iSensA, a system for integrating and collecting information from sensors. The solution implements a multi-sensor monitoring system and then expands the monitoring concept to an IoT solution, by employing multi-network access, Web services, database and web and mobile applications for user interaction. iSensA system is highly configurable, enabling several monitoring solutions with different types of sensors. Experiments have been performed on real application scenarios to validate and evaluate our proposition.
This paper presents a new approach to help redesigning waste management for the cities of the future. The current state of tracking waste containers is rigid, inefficient and hard to oversee. Although attempts have been made in the past using radio-frequency identification for waste container detection, it has shown problems like flexibility, cost and environmental impact. We propose and demonstrate a solution based on the use of computer vision techniques, for object detection and classification, towards the differentiation between different types of waste containers.
This study aims to contribute to depict Portugal's image as a touristic destination and tries to describe Portugal as it was seen by former travellers. It analyses written documents brought to us by English speaking travellers during the third quarter of the 19th century. Speci?cally, it analyses books written over the timespan 1850-1875. A mixed approach is performed to conduct the analysis, systematic literature review, content analysis and science mapping technics are employed. Findings show references to multiple important aspects related to Portugal's image, such as landscapes, food, accommodation, and infrastructures.

LiveColour Colourinhabiting, is the case study of my PhD in Design, under the theme –Collaborative Paintings in Residential Facades, and is the name of the action taking place in the São Cristóvão village, Alentejo, Portugal, writ large on residential facades, that tells a story in pictures from a local worldview, and conveys a message of hope, (in participant’s own words). The research indicates that, beyond the local participation and empowerment that such process engenders, it also satisfies an individual’s need for affection, identity and creativity by exploring the relationship between each resident and her creation of own public space. This paper contemplates also the designer´s role as a catalyst for questioning personal and collective values, their substance and expression. The case study has contributed to the creation of a future culture, promoting design as both a discipline of inner development and generator of social capital.
This study explores the nature of the relationship between market orientation and business performance and the mediating role of customer loyalty in this relationship. Empirical analysis was based on a sample from the Western European hotel industry. Research results indicate that market orientation has a positive direct effect on business performance and that the effects of market orientation on business performance are mediated through customer loyalty. Market orientation produces a positive effect on customer loyalty, which in turn has a positive effect on business performance, showing that market orientation has a significant and positive indirect effect on business performance. These findings suggest potential major implications for the hotel industry. For example, by developing a market-oriented organization, hotels could produce positive effects on customer loyalty and consequently on their business performance.

Introduction: Higher Education Institutions (HEI) are allegedly preparing students for a globalized working area where people will need to be ready to communicate effectively in one or more foreign languages in international working environments, which puts a lot of pressure on how foreign languages (FL) are learned in Higher Education (HE).
Methods: This article explores how a FL or learning through a FL could be approached in HEI, focusing mainly on what employers claim in terms of skills of recent graduates or on-the-job workers. Case studies are used, combining interviews to employers and questionnaires to HE students to find out their perceptions on FL learning requirements for greater employability. Conclusions: A series of recommendations are made for HEI on how to promote students’ employability skills; on the best practices for the development of intercultural communicative competence and FL skills to communicate effectively in international or digitally-mediated working environments; as well as on how to prepare the teaching staff for emerging trends that involve using a FL as medium of instruction or CLIL, a content and language integrated approach. These testify to the importance of learning a FL or through a FL, as well as the need to combine transversal skills development in connection to FL learning.
