Abstract
Of all the technologies born in the 20th century the software industry is the sole one that has kept a large dependency on human physical effort in order to produce the necessary code for an Information Technology system to perform. This paper analyses that evolution in view of today's state-of-the-art regarding automatic code generation based on model definitions for critical business purposes. The social, financial and technological benefits will be addressed as they are disruptive and will affect different levels of society as we know it. Several testimonies were also sought regarding the technology described herein and how it may affect us in our day-to-day lives. We conclude that the software industry is in the midst of a major revolution - which has arrived late in comparison to other industries related to technology and which have decreased the reliance on human labour some time ago.

Abstract
O 1.º SEVj – Seminário sobre Ensino de Videojogos – decorreu no dia 13 de setembro de 2019, organizado pela Sociedade Portuguesa de Ciências dos Videojogos (SPCV) e pelo LabTE da Faculdade de Psicologia e de Ciências da Educação da Universidade de Coimbra. O evento teve como objetivo reunir a comunidade nacional que leciona sobre videojogos para promover sinergias e um conhecimento mútuo mais detalhado. Os participantes foram convidados a partilhar a sua experiência, apresentando práticas bem-sucedidas e reflexões sobre o tema dos videojogos e o seu ensino. Visa-se com este evento, e suas futuras edições, contribuir para aprimorar a qualidade da formação dos profissionais nas áreas dos videojogos em Portugal. Este documento dá conta das conclusões do evento e apresenta os resumos das comunicações apresentadas pelos participantes. O seminário decorreu em quatro blocos de apresentações de comunicações individuais seguidas de um período de debate plenário sobre as mesmas. O final do evento foi dedicado a um plenário mais vasto convidando todos os participantes para debate e reflexão global, sob a linha diretora: “O que deve advir de maior sentido de corpo nesta comunidade académica?” Os contributos foram coligidos ao vivo em documento online, projetado e editado durante o debate. Esse documento foi posteriormente partilhado com todos os participantes, para dar continuidade à sua elaboração e correção, tendo originado a versão aqui apresentada.

Abstract
The proposed technique demonstrates a fiber ring resonator interrogated by an optical time domain reflectometer (OTDR), for intensity sensing. By using this methodology, a cavity round trip time of 2.85 mu s was obtained. For a proof of concept, a long-period grating was inserted in the resonant cavity operating as a curvature sensing device. A novel signal processing approach was outlined, regarding to the logarithmic behavior of the OTDR. Through analyzing the experimental results, an increase in the measured sensitivities was obtained by increasing applied bending. With curvatures performed from 1.8 m(-1) to 4.5 m(-1), the sensitivity values ranged from 2.94 dB center dot km(-1) to 5.15 dB center dot km(-1). In its turn, the sensitivities obtained presented a linear behavior when studied as a function of the applied curvature, following a slope of 0.86x10(-3) dB. The advantages of applying this technique were also discussed, demonstrating two similar fiber rings multiplexed in a series of configurations.

Abstract
With the increase in the number of electric vehicles (EVs), there might be substantial problems due to the charging transactions in the power system and the balancing between supply and demand sides can be provided in the modern power system by considering EVs as a flexible load. EVs cannot directly participate in buying and selling energy from/to the electricity market because of their relatively low energy and power capacities. In this manner, considering that EVs are generally parked during the day, an EV parking lot (EVPL) can offer economic charging opportunities to EV owners as multiple EVPLs can offer/bid for the buying/selling from/to the electricity market through an EVPL aggregator (EVPLA). In this study, a model in which the EVPLA offers/bids for the day-ahead (DA) and secondary reserve market in order to minimize the total cost is propounded. Furthermore, uncertainties related to the EV owners' behavior and market prices are handled by considering scenarios with real data in a stochastic manner. In addition, the EVPLA also takes into account the comfort of the EV owners when carrying out this operation. The comfort of EV owners as an essential issue similar to serving EV owners more economically is achieved by sustaining the minimum desired charge level by EV owners at the departure time. The results consist of a set of case studies to reveal the effectiveness of the proposed model considering the pricing conditions in Turkey, Finland, and USA-PJM DA and reserve markets. According to the results of the study, it is observed that an EV aggregator participating in DA and RE markets can make a significant profit for the three market conditions. An important result is also that the profit by the participation in reserve markets increases significantly compared to solely DA market participation.

Abstract
The stability and monitoring of AC microgrids (AC MG) are greatly influenced by gathering sufficient and precise information. Since installing several sensors on AC MGs is costly and increases AC MG ripple, integrating a minimum number of cost-effective sensors is preferred. In this paper, a joint-estimating advanced augmented-Kalman filter (KF) to estimate the current of the AC MG and unknown time-varying loads from the noisy measurement of the AC bus voltage is developed. The proposed approach also provides smooth and noise-less information from the measured voltage. The presented method has less complexity to handle and as a robust approach, it would be capable of dealing with uncertainties due to the load, which can be linear, nonlinear, or unbalanced. The joint-estimating augmented-KF outputs can be then utilized in the monitoring, fault detection, and control design purposes. The developed framework is tested on an AC MG supplying time-varying load and numerical results verify the applicability and accuracy of the developed technique to estimate the load and filter currents.

Abstract
Software Operational Profile (SOP) is a software specification based on how users use the software. This specification corresponds to a quantitative representation of software that identifies the most used software parts. As software reliability depends on the context in which users operate the software, the SOP is used in software reliability engineering. However, there are evidences of a misalignment between the software tested parts and SOP. Therefore, this paper investigates a possible misalignment between SOP and the tested software parts to obtain, based on experimental data, more evidence of this misalignment. We performed an exploratory study composed of four activities to verify: a) whether there are significant variations in how users operate the software; b) whether there is a misalignment between SOP and the tested software parts; c) if failures occur in untested SOP parts in case of misalignment; d) in case of misalignment between SOP and untested software parts, whether a test strategy based on the amplification of the existent test set with additional test data generated automatically, can contribute to reduce the misalignment. We collected data form four software while users were operating them. We analyzed this collected data in an attempt to reach the goals of this work. To evaluate the originality of this research, we performed a Literature Systematic Review (SLR) and presented its conclusions. The obtained results evidence that there are significant variations in how users operate the software and also that there is a misalignment between SOP and the tested software parts when we evaluated the four software mentioned above. There are also indications of the occurrence of failures in the untested SOP parts. Although the test strategy mentioned above has reduced the possible misalignment, the test strategy is not enough to avoid it, thus denoting the need of specifics test strategies using SOP as a test criterion. These results indicate that SOP becomes relevant not only to software reliability engineering but also to contribute to testing activities, regardless of the adopted strategy.
