Sistema de apoio ao utilizador de transportes públicos

Nos dias de hoje usar o transporte público para nos deslocarmos de uma determinada origem para um determinado destino é uma realidade na vida da maioria das pessoas. Muitas destas deslocações fazem parte da rotina diária do cidadão, que depende destes transportes para as suas atividades do dia-a-dia. Nos últimos anos, o número de cidadãos que usa os transportes públicos como meio de deslocação tem vindo a aumentar consideravelmente. Contudo, a maioria dos operadores de transportes públicos pecam pela falta de pontualidade dos seus serviços, e pela falta de informação disponível ao cidadão acerca dos horários dos mesmos em tempo real. Tendo este problema em conta, foi desenvolvida uma solução capaz de realizar uma previsão do tempo de chegada de um transporte público, ao longo de todo o seu serviço. Previsão essa que é atualizada ao longo do percurso de forma a reduzir a margem de erro da informação apresentada. Com esta informação o cidadão pode planear melhor o seu dia e decidir qual é a melhor altura para se deslocar para a paragem, evitando ao máximo a perda de tempo à espera do seu transporte público. A solução final foi desenvolvida com a ajuda da empresa BEWARE e teve como objetivo a criação de uma aplicação web capaz de apresentar os tempos de espera dos autocarros em diferentes tipos de vista, bem como o acompanhamento do mesmo ao longo do percurso. Toda a informação utilizada na aplicação web foi criada por dois serviços de apoio que efetuam o controlo do autocarro ao longo do percurso, bem como os cálculos da previsão dos tempos de espera. O projeto foi dividido em quatro constituintes que foram repetidas durante o desenvolvimento da solução. A primeira constou na análise do problema, no levantamento e definição dos requisitos. A segunda incluiu o desenvolvimento de um algoritmo capaz de validar a posição do autocarro ao longo do seu percurso, detetando a paragem onde este se encontra e a hora de chegada à mesma. A terceira abrangeu o desenvolvimento de um algoritmo capaz de prever o tempo de chegada de um autocarro às paragens definidas na sua rota, recorrendo ao histórico de viagens realizadas anteriormente. A quarta consistiu no desenvolvimento da aplicação web, implementando todas as funcionalidades necessárias para que a aplicação consiga realizar o acompanhamento do autocarro no percurso, a consulta dos tempos de chegada e da previsão dos tempos às paragens seguintes recorrendo a três tipos de vistas diferentes, e a possibilidade de agendar notificações de forma a receber no email as previsões dos tempos de chegada nos dias e horas mais significativos para o utilizador.

Is There Sufficient Training of Health Care Staff on Noise Reduction in Neonatal Intensive Care Units? a Pilot Study From NeoNoise Project

Evidence indicates that exposure to high levels of noise adversely affects human health, and these effects are dependent upon various factors. In hospitals, there are many sources of noise, and high levels exert an impact on patients and staff, increasing both recovery time and stress, respectively. The goal of this pilot study was to develop, implement and evaluate the effectiveness of a training program (TP) on noise reduction in a Neonatal Intensive Care Units (NICU) by comparing the noise levels before and after the implementation of the program. A total of 79 health professionals participated in the study. The measurements of sound pressure levels took into account the layout of the unit and location of the main sources of noise. General results indicated that LAeq levels before implementation of the training program were often excessive, ranging from 48.7 ± 2.94 dBA to 71.7 ± 4.74 dBA, exceeding international guidelines. Similarly following implementation of the training program noise levels remained unchanged (54.5 ± 0.49 dBA to 63.9 ± 4.37 dBA), despite a decrease in some locations. There was no significant difference before and after the implementation of TP. However a significant difference was found for Lp, Cpeak, before and after training staff, suggesting greater care by healthcare professionals performing their tasks. Even recognizing that a TP is quite important to change behaviors, this needs to be considered in a broader context to effectively control noise in the NICU.

O processo de outsourcing: Implementação de um processo de engarrafamento e embalagem.

Outsourcing is a management strategy through which an organization transfers work, responsibilities and decision power to an external source. In the present scenario of global competitiveness, where firms have to react more quickly to changes in markets, outsourcing stands out as a strategy that, if adequately used by the organizations, can leverage the differentiation between one firm and its competitors. The growing use of outsourcing as a management strategy by organizations, results from the maturity reached in their use by organizations and an increase of the offer by service providers. With the increasing use of outsourcing, the complexity and the risk associated have also risen. Understanding the perspective of the customer and of the service provider and the outsourcing processes framework should contribute to a success of the customer / service provider relationship and enhance the benefits and reduce their risks. In this work, there is a contextualization of outsourcing, different methods for managing the outsourcing process from the customer's and the service provider perspective are discussed, and a methodology for managing the outsourcing process from the perspective of the service provider is proposed. The methodological approach used in this work was the case study. The case study discusses an initiative to outsource a process of bottling and packaging in the Port Wine industry. In this study it was concluded that the methodology proposed is suitable for the management of the outsourcing process by the service provider.

Aquaponics System - An EPS@ISEP 2014 Spring Project

The goal of this project, one of the proposals of the EPS@ISEP 2014 Spring, was to develop an Aquaponics System. Over recent years Aquaponics systems have received increased attention due to its possibilities in helping reduce strain on resources within 1st and 3rd world countries. Aquaponics is the combination of Hydroponics and Aquaculture and mimics a natural environment in order to successfully apply and enhance the understanding of natural cycles within an indoor process. By using this knowledge of natural cycles it was possible to create a system with the capabilities similar to that of a natural environment with the benefits of electronic adaptions to enhance the overall efficiency of the system. The multinational team involved in its development was composed of five students, from five countries and fields of study. This paper covers their solution, involving overall design, the technology involved and the benefits it could bring to the current market. The team was able to achieve the final rendered Computer Aided Design (CAD) drawings, successfully performed all the electronic testing, and designed a solution under budget. Furthermore, the solution presented was deeply studied from the sustainability viewpoint and the team also developed a product specific marketing plan. Finally, the students involved in this project obtained new knowledge and skills.

Design and Development of a Solar Dryer for Microalgae Retrieval - An EPS@ISEP 2013 Spring Project

Currently excessive fossil fuel consumption has become a serious problem. People are searching for new solutions of energy production and there are several options to obtain alternative sources of energy without further devastating the already destroyed environment. One of these solutions is growing microalgae, from which biodiesel can be obtained. The microalgae production is a growing business because of its many useful compounds. In order to collect these compounds microalgae must first be harvested and then dried. Nowadays the solutions used for drying use too much energy and therefore are too expensive and not sustainable. The goal of this project, one of the possible choices during the EPS@ISEP 2013 Spring, was to develop a solar microalgae dryer. The multinational team involved in its development was composed of five students, from distinct countries and fields of study, and was the responsible for designing a solar microalgae dryer prototype for the microalgae laboratory of the chemical engineering department at ISEP, suitable for future tests and incorporating control process (in order not to destroy the microalgae during the drying process). The solar microalgae dryer was built to work as a distiller that gets rid of the excess water from the microalgae suspension. This paper presents a possible solution for this problem, the steps to create the device to harvest the microalgae by drying them with the use of solar energy (also used as an energy source for the solar dryer control system), the technologies used to build the solar microalgae dryer, and the benefits it presents compared to current solutions. It also presents the device from the ethical and sustainable viewpoint. Such alternative to already existing methods is competitive as far as energy usage is concerned.

Design and Implementation of a Biologically Inspired Flying Robot - An EPS@ISEP 2014 Spring Project

The goal of this EPS@ISEP project proposed in the Spring of 2014 was to develop a flapping wing flying robot. The project was embraced by a multinational team composed of four students from different countries and fields of study. The team designed and implemented a robot inspired by a biplane design, constructed from lightweight materials and battery powered. The prototype, called MyBird, was built with a 250 € budget, reuse existing materials as well as low cost solutions. Although the team's initial idea was to build a light radio controlled robot, time limitations along with setbacks involving the required electrical components led to a light but not radio controlled prototype. The team, from the experience gathered, made a number of future improvement suggestions, namely, the addition of radio control and a camera and the adoption of articulated monoplane design instead of the current biplane design for the wings.

Development of Biomimetic Robots in the EPS Engineering Programme Capstone Project

This paper proposes the development of biologically inspired robots as the capstone project of the European Project Semester (EPS) framework. EPS is a one semester student centred international programme offered by a group of European engineering schools (EPS Providers) as part of their student exchange programme portfolio. EPS is organized around a central module (the EPS project) and a set of complementary supportive modules. Project proposals refer to open multidisciplinary real world problems. Its purpose is to expose students to problems of a greater dimension and complexity than those faced throughout the degree programme as well as to put them in contact with the socalled real world, in opposition to the academic world. Students are organized in teams, grouping individuals from diverse academic backgrounds and nationalities, and each team is fully responsible for conducting its project. EPS provides an integrated framework for undertaking capstone projects, which is focused on multicultural and multidisciplinary teamwork, communication, problem-solving, creativity, leadership, entrepreneurship, ethical reasoning and global contextual analysis. The design and development of biologically inspired robots allows the students to fulfil the previously described requirements and objectives and, as a result, we recommend the adoption of these projects within the EPS project capstone module for the benefit of engineering students.

Design and Implementation of a Biologically Inspired Swimming Robot - An EPS@ISEP 2014 Spring Project

This paper presents the development of a fish-like robot called Bro-Fish. Bro-Fish aims to be an educational toy dedicated to teaching mechanics, programming and the physics of floating objects to youngsters. The underlying intention is to awaken the interest of children for technology, especially biomimetic (biologically inspired) approaches, in order to promote sustainability and raise the level of ecological awareness. The main focus of this project was to create a robot with carangiform locomotion and controllable swimming, providing the opportunity to customize parts and experiment with the physics of floating objects. Therefore, the locomotion principles of fishes and mechanisms developed in related projects were analysed. Inspired by this background knowledge, a prototype was designed and implemented. The main achievement is the new tail mechanism that propels the robot. The tail resembles the undulation motion of fish bodies and is actuated in an innovative way, triggered by an elegant movement of a rotating helicoidal. First experimental tests revealed the potential of the proposed methodology to effectively generate forward propulsion.
