Indoor-DSL: A Model Driven Approach to Modeling Indoor Representation Models for a Navigation Infrastructure

Abstract: Internal positioning and navigation tools provide important information about semantic aspects of buildings, however information about indoor maps construction is not usually available and designing tools used for modeling indoor environments are hard to use or expensive. In this article, a Domain Specific Language (DSL) for modeling indoor environments is presented, allowing to create internal representation models, independent of platform. This work aims to create indoor map models for infrastructure of Indoor Navigation System (INavigS), where all the domain concepts present in the tool are used to specify models. The principles of the Model Driven Approach (MDA) are applied to define a metamodel language. In addition, a graphical interface is provided for modeling indoor environment models used by INavigS, allowing to model internal indoor environments quickly and easily, keeping the focus on concerns related to the domain of navigation infrastructure.

Ensuring privacy in the application of the Brazilian general data protection law (LGPD)

Abstract: Currently, many organizations make use of the personal data of their users. Personal data is the set of information that can lead to the identification of a specific person and, therefore, this information is generally vital for the operations and business continuity of organizations. Consequently, the relevance of adopting methodologies that guarantee the protection and privacy of user information is indispensable to prevent the leaking of sensible information. Therefore, laws were created to establish essential requirements for organizations to provide support and protection to the personal data of users, such as the General European Data Protection Regulation (GDPR) and the Brazilian General Data Protection Law (LGPD). This work aims to develop a framework to support ICT professionals in adapting companies to the requirements demanded by the LGPD. To achieve the purpose, a framework based on the BEST methodology (Business Engaged Security Transformation) was proposed. This framework has a sustainable approach and can be implemented by any organization. A survey was carried out to collect the perception of Information and Communication Technology (ICT) practitioners in relation to adherence to LGPD adaptation actions by organizations. As a result, we identified a weakness in the privacy and information security management methodology implemented in organizations, which, in the future, may result in risks and damage to user information.

Uma metodologia de localização Indoor para smartphones em ambientes de Cidades Inteligentes.

Abstract: Sistemas de localização em ambientes internos (indoor) têm atráıdo interesses das mais variadasáreas, permitindo a otimização e o surgimento de novos serviços. Com a expansão de cenários instrumentados com dispositivos IoT (do inglês Internet of Things), os sistemas de localização ganham uma importância ainda maior, proporcionando referências para uma localização baseada nos transmissores do ambiente. Neste trabalho, apresentamos uma metodologia para um sistema de localização indoor para smartphones, capaz de rastrear a movimentação de um usuário e definir a sua localização de forma mais precisa, através da fusão de dados de diferentes fontes e Filtro de Kalman, tais como sensores inerciais, redes sem fio Wi-Fi e BLE instalados no ambiente.

INavigS: uma infraestrutura de software ciente de contexto para navegação indoor

Abstract: Computacao sensivel ao contexto e uma area de pesquisa da computacao ubiqua que visa fornecer servicos e/ou informacoes sem retirar o foco do usuario da tarefa corrente. Servicos baseados em localizacao, por sua vez, enquadram-se como um tipo especial de aplicacoes sensiveis ao contexto, onde a localizacao assume um papel primordial. Devido a evolucao das tecnologias de posicionamento e o fato das pessoas passarem a maior parte do tempo no ambiente indoor, a demanda por servicos baseados em localizacao indoor nao para de crescer. Entretanto, o desenvolvimento dessas aplicacoes envolve superar diversos desafios. Em particular, para aplicacoes que fazem o uso de servicos de navegacao indoor, uma das categorias mais importantes, os desafios incluem: obtencao da localizacao e orientacao do usuario, a representacao do espaco indoor, a geracao de rotas customizadas, a geracao de instrucoes ao longo da rota, o gerenciamento de energia e a inexistencia de APIs. Diante desses desafios e objetivando diminuir o esforco necessario para o desenvolvimento dessas aplicacoes, este trabalho propoe uma infraestrutura de software sensivel ao contexto e suportada por dispositivos moveis que forneca servicos transparentes de posicionamento e navegac

Developing a Web Application for Indoor Map Data Management

Abstract: Author Title Number of Pages Date Juhani Lavonen Developing a Web Application for Indoor Map Data Management 53 pages + 14 appendices 7 May 2018 Degree Bachelor of Engineering Degree Programme ICT Professional Major Mobile Solutions Instructors Mikko Virkkilä, CTO Olli Alm, Senior Lecturer The goal of this thesis was to create an effective and user-friendly application for managing indoor map data. The work was done for a company called Steerpath. This thesis approaches the indoor map data management from two perspectives: from the point of view of user experience and how to manage geospatial data in the most efficient way. During this study two comprehensive surveys were conducted among the employees of Steerpath. The first survey was conducted at the beginning of the project and it was about gathering user requirements for the product. After analysing the results of the survey, the development of the product began. The second survey was a usability test which was held at the time of internal release of the developed application. Based on the results and feedback from the usability test, the application was proven to meet the requirements that were set for it. The employees felt that the application makes the map maintenance and management process more user friendly and efficient.

Application of model-driven engineering to multi-agent systems : a language to model behaviors of reactive agents

Abstract: Des nombreux utilisateurs des systemes multi-agents (SMA) sont tres souvent decourages de modeliser et simuler dans les plates-formes actuelles SMA. Plus precisement, modeliser la dynamique d'un systeme (en particulier les comportements de l'agent) est tres souvent vu comme un defi pour les utilisateurs de SMA. Dans le domaine des systemes socio-ecologiques (SES), cet inconvenient est plus souvent observe une fois que les experts de domaine en SES sont rarement des programmeurs. De plus, la majorite des plateformes SMA n'a pas ete concue en prenant en considerant le fait que les experts de domaines ne sont pas des programmeurs. On constate que la majeure partie des outils MAS ne sont pas dedies a SES, ou qu'ils ne possedent pas un formalisme comprehensible pour representer les comportements de SMA. En outre, comme ces outils sont dependant des plateformes, un modele realise dans une plateforme SMA ne peut pas etre correctement utilise dans une autre plate-forme en raison de l'incompatibilite entre ces plateformes SMA. Afin de surpasser ces limitations, nous proposons un langage dedie au domaine SES pour decrire les comportements des agents reactifs, quelle que soit la plate-forme utilisee pour la simulation des SMA. Pour ce faire, nous avons applique l’approche de l’ingenierie dirigee par les modeles (IDM), une approche qui fournit des outils pour developper des langages dedies a partir d'un meta-modele (syntaxe abstraite), des editeurs textuels avec coloration syntaxique (pour la syntaxe concrete) et des outils des generateurs de code (pour la generation de source code a partir d'un modele). En consequence, nous avons mis en œuvre un langage et un editeur de texte qui permet a des experts du domaine SES de decrire les comportements de trois manieres differentes qui sont fermees a leur expression naturelle : sous forme d'equations quand ils sont familiers avec celles-ci, en tant que sequence d'activites proche du langage naturel ou comme un diagramme d'activite pour representer les decisions et une sequence de comportements en utilisant un formalisme graphique. Pour montrer la generalite, nous avons egalement developpe des generateurs de code ciblant deux plates-formes differentes SMA (Cormas et Netlogo). Nous avons teste les generateurs de code en mettant en œuvre deux modeles SES avec le langage dedie developpe. Le code genere obtenu a ete genere pour les deux plates-formes SMA Cormas et NetLogo, et simule avec succes dans un des deux plateformes. Nous avons conclu que l'approche IDM fournit des outils adequats a developper des langages dedies et des generateurs de code pour faciliter la modelisation et la simulation SMA par des non-programmeurs. En ce qui concerne le langage developpe, bien que l’aspect comportemental de la simulation MAS fasse partie de la complexite de la modelisation en SMA, il y a encore d'autres aspects essentiels du modele et de la simulation de SMA qui sont encore a etre explores, tels que l'initialisation et les points de vue sur un le monde simule d’un modele.
