Análisis de los concursos en redes sociales como herramienta del marketing de influencia

Los likes, las publicaciones, compartir o mencionar a un amigo, son expresiones que forman parte de nuestro día a día. Las redes sociales se han convertido en el 50% de nosotros y pasamos mucho tiempo (y cada vez más) en ellas. Debido a este aumento del uso de las redes sociales, el marketing de influencia va creciendo con el paso de los años, así como las herramientas y métodos utilizados para llegar a los consumidores. Una de esas herramientas son los concursos online o en redes sociales por los que apuestan cada vez más las empresas y que están liderados por influencers. Los concursos aumentan la actividad en los perfiles de los distintos influencers y, a través de ellos, se logra que los seguidores conozcan nuevos productos o servicios. El objetivo principal del trabajo es el análisis de los concursos de los influencers en las redes sociales más utilizadas por los usuarios y cuál es su repercusión en el comportamiento final de compra.Likes, posts, share or mention a friend, are expressions that are part of our day to day. Social networks have become 50% of us and we spend a lot of time (and more and more) in them. As a consequence of this increase in the use of social networks, influence marketing is growing over the years, as well as the tools and methods used to reach consumers. One of those tools is the online contests or social networks so companies are betting more and more, and that are led by the influencers. The contests increase the activity in the profiles of the different influencers and, through them we get fans to know new products or services, so it seems that with them we all won. The main objective of the work is the analysis of the influencers competitions in the social networks plus the applications of the users and their repercussion in the final behavior of the purchase.Departamento de Organización de Empresas y Comercialización e Investigación de MercadosGrado en Derecho y Grado en Administración y Dirección de Empresa

Study of application of electromechanical actuators to deploy control surfaces according to More Electrical Aircraft concept.

Transportation represents a 20% of green-house effect gases emissions worldwide. There is a trend to move towards greener powered systems, such as electric ones. More Electric Aircraft (MEA) is a new concept into the aircraft industry which is trying to increase the usage of electrically powered systems in aeroplanes. This project reviews the available technologies for MEA in special regard to flight control surfaces actuators. Conventional hydraulic actuators in aircraft systems are low efficient and require high maintenance tasks and a heavy infrastructure. Powered-by-wire systems are being broadly applied into aeroplanes to improve the maintainability, reliability and also manoeuvrability of the next generation of aeroplanes. Throughout the project different fields involved in the effective development of new electromechanical actuators are inspected. First, the generation and power conversion of electric power into a plane. Second, the technologies concerning the building block of an electromechanical actuator in three main aspects: electric layout, mechanical layout and potential failures. Third, the monitoring devices and redundant architecture that would satisfy the continued airworthiness regulations. Finally, a mock-up for simulating and demonstrating purposes is designed and the most proper pattern nowadays for an electromechanical actuator for flight control surfaces is presented together with further work of MEA for the successful implementation of electromechanical actuators into the next generation of aircraft

Integration of ROS2 with a simulation environment

Dissertação de mestrado integrado em Engenharia InformáticaCurrently, the University of Minho owns a driving simulator, from now on referred to as Driving Simulator Mockup 2-Wheeler (DSM-2W), which mimics a real driving environment for motorcycles. This simulator can reproduce diverse driving scenarios, like driving on different roads, traffic, and weather conditions, and is mostly used to test how the driver reacts to stimulus from subsystems under test in a particular scenario. The simulator has several components, namely, the Mock-up, which represents the motorcycle physically, the software responsible for the simulation environment, that is also projected on a screen, called SILAB [1] as well as several other subsystems and respective software, which all together form a complex distributed system. SILAB creates realistic graphic environments, has different models to control the behavior of other drivers and pedestrians, generates 3D sounds, and facilitates the personalization of the simulation scenario. Robot Operating System 2 (ROS2) [2] provides a set of tools and software libraries that facilitate the develop ment of robot systems and applications. With the increasing reliance on software, sensors, and actuators in the automotive domain, it makes sense to view cars [3] and motorcycles as robots. Therefore, it also makes sense to use ROS2 in the simulation domain to solve the problems at hand. This dissertation describes how ROS2, a well-known and accepted middleware for robotic applications, can also play a role in these contexts acting as a universal interface between motorcycle simulators and external subsystems and thereby significantly improving the system’s expansibility and those subsystems’ portability and reusability.A Universidade do Minho possui um simulador de motas, denominado Driving Simulator Mockup 2-Wheeler (DSM-2W), que imita um ambiente real de condução de motas. Esta ferramenta consegue reproduzir diversos cenários de condução, como conduzir em diferentes condições de estrada, tráfego, bem como em diferentes condições meteorológicas. Esta ferramenta é sobretudo usada para testar como o condutor reage a estímulos de vários sub-sistemas em teste em cenários particulares. O simulador possui diversos componentes, o Mock-up, que representa a mota fisicamente, o software responsável pela projeção do ambiente de simulação no ecrã, chamado SILAB [1], mais um conjunto de sub-sistemas e o respetivo software, que no conjunto formam um complexo sistema distribuído. O SILAB cria ambientes de simulação realistas, tem diferentes modelos para controlar o comportamento dos outros condutores e dos pedestres, gera sons 3D e facilita a personalização do cenário da simulação. O Robot Operating System 2 (ROS2) possui um conjunto de ferramentas e bibliotecas para desenvolver aplicações para robôs [2]. Com o aumento do uso de software, sensores, e atuadores no contexto automóvel, faz sentido equiparar veículos automóveis [3] e motas a robôs Portanto, também faz sentido usar o ROS2 para resolver problemas neste contexto. O objetivo desta dissertação passa por mostrar como o ROS2, um middleware bastante utilizado em aplicações para robôs, pode ter um papel importante em contextos de simulação ao atuar como uma interface universal entre sub-sistemas a testar e um simulador de motas e consequentemente melhorar a extensibilidade do simulador e a portabilidade e reusabilidade desses sub-sistemas

Data center visualization

Dissertação de mestrado integrado em Engenharia InformáticaAs more projects are financed by public institutions, demonstrating tasks and other information developed is increasingly required. Traditional monitoring tools like Prometheus are used in data centers to collect data from the machines and supervise them as the devices can malfunction and make the service unavailable. Currently, applications like Prometheus that display the machines’ performance are limited to a restricted set of people: the data center managers. These applications have limited data visualization methods since their focus is on retrieving the data from the machines. These applications are associated with specialized frameworks in showing the machines’ performance. These frameworks present the data in several visualization methods, such as graphic lines and gauge graphics. However, the forms of exposing data are not attractive for people in general. So, other ways to expose the data need to be developed. Data visualization in three dimensions can expose data more attractively. Besides, 3D has some advantages over traditional ways. With a data friendlier exposition, catching the attention of people who do not manage the data center is easier. This project aims to build an application to expose the data center’s data in a 3D scenario. The data exposed are the machines’ tasks, components, and performance. By exposing the data center’s tasks and other information to the general public, the application can present to the viewer the usefulness of the data center. The application must have its components flexible, so any data center can use it. Moreover, those data centers should expose any visualization they desire through plugins. To complete the goals, first, different techniques to explore and view the data are investigated. Several applications that expose data from a data center are analyzed to know the current status of these applications. Furthermore, different scenarios are constructed based on the research made. Using a tool capable of handling web requests makes the application available to everyone. Besides, the application is flexible in some parts of the architecture to be adaptable to any framework. So, any data center can use the application. Those parts are the server that contains the machines’ performance data and the database management system. The system allows the creation of a plugin to communicate with the machine’s performance server. Following a simple interface, a new plugin can be developed with relative ease. Besides, the webserver is replicable, making it adaptable to the data center’s needs. Moreover, the application allows the creation of arbitrary 3D scenarios. By following a set of steps a simple 3D scenario can be built, including the visualization and communication server stages. Such a scenario can be expanded freely, as long as the communication API is observed. The created scenario functions as a plugin that can be inserted into the application effortlessly. The application’s usefulness is validated through an experience with information from a real data center. Finally, the application’s performance is corroborated, supporting a considerable amount of concurrent requests.Como há um número maior de projetos financiados por instituições públicas, é necessário revelar que tarefas e outras informações a instituição desenvolve. Ferramentas de monitorização como o Prometheus são usadas em centros de dados para recolher o desempenho das máquinas e supervisioná-las uma vez que podem ter problemas tornando o serviço indisponível. Aplicações como o Prometheus que exibem o desempenho das máquinas são limitados a um conjunto restrito de pessoas: os gestores dos centros de dados. Estas aplicações têm métodos de visualização limitados, uma vez que se focam em obter os dados das máquinas. Estas aplicações são associadas com aplicações especializadas em mostrar o desempenho das máquinas. Os dados são apresentados em vários métodos de visualização, como gráficos de linhas e de área. No entanto, estas formas não são atraentes para o público em geral. Portanto, é preciso usar outras formas de expor os dados. Visualização de dados em três dimensões pode expor os dados de uma forma mais eficiente. Além disso, 3D tem algumas vantagens em relação às formas tradicionais. Com um cenário mais amigável, é mais fácil captar a atenção das pessoas. Este projeto tem o objetivo de construir uma aplicação para expor os dados do centro de dados em 3D. Os dados expostos são as tarefas, o desempenho e os componentes das máquinas. Ao expor as tarefas para o público em geral a aplicação pode apresentar a utilidade do centro de dados. A aplicação deverá ter os componentes flexíveis para que qualquer centro de dados o possa usar. Além disso, os centros de dados deverão expor qualquer tipo de visualização que desejarem. Para completar os objetivos, são investigadas diferentes técnicas de exposição de dados. São analisadas várias aplicações que expõem os dados de um centro de dados para conhecer o estado atual das mesmas. Além do mais, são construídos vários cenários com base nos dados da investigação. Ao usar uma ferramenta capaz de lidar com pedidos web torna-a disponível para todos. A aplicação também deve ser flexível em alguns dos componentes para serem adaptados a qualquer ferramenta. Desta forma qualquer centro de dados pode usar a aplicação. As partes flexíveis devem ser o servidor que contém os dados do desempenho das máquinas e a base de dados. O sistema permite o uso de diferentes plugins para comunicar com esse servidor. Ao seguir um conjunto de passos a criação do plugin é relativamente fácil. O servidor aplicacional é replicável, tornando o sistema adaptável para as necessidades do centro de dados. A aplicação permite o desenvolvimento de novos cenários 3D. Ao seguir um conjunto de passos é criado um cenário 3D simples, incluindo os passos da visualização e comunicação com o servidor. O cenário pode ser expandido, desde que siga a API de comunicação. O cenário criado funciona como um plugin que pode ser adicionado na aplicação facilmente. A utilidade da aplicação é validada através de uma experiência com dados reais de um centro de dados. Por fim, o desempenho da máquina é validado, uma vez que suporta uma quantidade considerável de pedidos concorrentes

Cryptic diversity, intraspecific phenetic plasticity and recent geographical translocations in Branchiomma (Sabellidae, Annelida)

The importance of identifying biological diversity accurately and efficiently is becoming more evident. It is therefore critical to determine the species boundaries between closely related taxa and to establish diagnostic characters that allow us to define species. This is not an easy task when species exhibit high intraspecific phenotypic plasticity or when distinct evolutionary lineages with an unusually large amount of genetic distinctiveness show no apparent morphological diversity (cryptic species). These phenomena appear to be common in the genus of fan worms Branchiomma (Sabellidae, Annelida), and consequently, taxonomic errors are widespread in the group. Moreover, some Branchiomma species have been unintentionally translocated outside the area where natural range extension is expected, increasing the taxonomic problems. We have performed a range of analytical methods including genetic distances, Bayesian inference, maximum likelihood, maximum parsimony, statistical parsimony analyses and general mixed Yule coalescent model to clarify the taxonomic status and assess the species boundaries of Branchiomma in Australia. This study shows that the traditional diagnostic morphological features are greatly homoplastic. Results also indicate that the diversity of Branchiomma in Australia is higher than previously reported and evidence some cases of high phenetic plasticity (in features previously considered as stable within species), high intraspecific genetic variability, cryptic species and several unexpected cases of translocations.© 2013 The Norwegian Academy of Science and Letters.This project was funded by an Australian Biological Resources Study (ABRS)/AM and Census of Marine Life (CReefs) grants to PH and MC.

Phylogeny of Oweniidae (Polychaeta) based on morphological data and taxonomic revision of Australian fauna

The family Oweniidae Rioja, 1917 is a small group of broadly distributed polychaetes whose relationships and position in the annelid tree are still poorly understood. A comprehensive revision of the group with reconsideration of character homologies and terminology under a phylogenetic framework was needed. We investigated the relationships of members of Oweniidae and other polychaetes by performing maximum parsimony analyses of 18 oweniid species of the five recognized genera to date and members of the families Siboglinidae, Sabellidae, Spionidae, Magelonidae, and Chaetopteridae. Phylogenetic hypotheses confirmed the monophyly of Oweniidae and suggested sister-group relationships with Magelonidae, although weakly supported. Analyses also recovered Oweniaand Myriowenia as monophyletic and allowed recognition of Myrioglobulaas a junior synonym of Myriochele based on the presence of acicular chaetae and the shape of the head. Implied weighting analyses supported these findings and recovered Galathowenia australis as sister group ofMyriochele. The presence of acicular chaetae justifies the consideration of this species as belonging to Myriochele. Nomenclatural changes are proposed for those species previously considered as members ofMyrioglobula, and these are: Myriochele antarcticacomb. nov., Myriochele japonicacomb. nov., Myriochele islandicacomb. nov., Myriochele malmgrenicomb. nov., and Myriochele australiscomb. nov. After analyses and definition of generic diagnostic features, other new combinations include Galathowenia eurystomacomb. nov. and Galathowenia haplosomacomb. nov., previously considered as members of Myriochele. Taxonomic revision of Australian collections revealed the presence ofMyriochele heruensis Gibbs, 1971, which is herein redescribed, and allowed the description of four new species: Galathowenia annae sp. nov.,Galathowenia arafurensissp. nov., Galathowenia quelissp. nov., andMyriochele australiensissp. nov., mostly from the east coast of Australia, in addition to the three recently well-documented species of Owenia. Australian species have been described, illustrated, and compared in detail with similar taxa. Distribution patterns and ecological notes have also been given. Keys to oweniid genera and Australian species are provided
