Utilização do método Multicritério AHP, na aquisição de um sistema ERP

The selection of an Enterprise Resource Planning (ERP) system is one of the most sensitive and highest impact processes in the area of information systems and technologies, because it supports and integrates the whole business of an organization. Hence the importance of deciding the best solution in order to contribute to the organization's competitiveness in a global and increasingly demanding market. Therefore, it is essential to provide tools to support decision making, turning complex and often intangible decisions into simple and quantifiable scenarios. This study addressed the adoption of the Analytical Hierarchy Process (AHP) multicriteria decision method to support the selection of an ERP system. The literature review was the source used to obtain the set of the most relevant criteria to be considered in this decision, which were subsequently validated through systematic application of various surveys of experts and people related to the field of ERP systems. To support the application of AHP, according to the model obtained in the study, it was developed a web application that will be available to the general public. The responsible for the acquisition of ERP systems can use it to easily apply the AHP method based on validated decision model. On the other hand, the web application can be used as a validation tool, allowing collecting data for future developments of the decision model.

A Travel Optimization System for Academic Environments

Carpooling initiated in America in the 1970s due to the oil crisis. However, over the past years, carpooling has increased significantly across the world. Some countries have created a High Occupancy Vehicle (HOV) lane to encourage commuters not to travel alone. In additional, carpool websites has been developed to facilitate the connection between the commuters, making it possible to create a compatible match in a faster and efficient manner. This project focuses on carpooling, especially in an academic environment since younger people are more likely to choose carpool. Initially, an intense research was made to examine carpool studies that occurred all over the world, following with a research of higher education institutes that use carpooling as a transportation mode. Most websites created carpools by targeting people from a specific country. These commuters have different origins and destinations making it more complicated to create compatible matches. The objective of this project is to develop a system helping teachers and students from an academic environment to create carpool matches. This objective makes it easier to create carpools because these students and teachers have the same destination. During the research, it was essential to explore, as many as possible, existing carpool websites that are available across the world. After this analysis, several sketches were made to develop the layout and structure of the web application that’s being implemented throughout the project. Once the layout was established, the development of the web application was initiated. This project had its ups and downs but it accomplished all the necessary requirements. This project can be accessed on the link: http://ipcacarpool.somee.com. Once the website was up and running, a web-based survey was developed to study the reasons that motivate people to consider carpooling as an alternative to driving alone. To develop this survey was used a tool called Survey Planet. This survey contained 408 respondents, which 391 are students and 17 are teachers. This study concludes that a majority of the respondents don’t carpool, however they will consider carpooling if there was a dedicated parking space. A majority of the respondents that carpool initiated less than a year ago, indicating that this mean of transportation is recent.

Controlo de um sistema domótico KNX

Esta dissertação descreve o estudo, concepção e desenvolvimento de uma aplicação baseada no sistema operativo Windows 8 que interage com um sistema domótico KNX, permitindo ao utilizador controlar a sua instalação domótica. Esta proposta, que combina a área de integração/instalação de sistemas domóticos e a de desenvolvimento de aplicações para Windows 8 e Windows 8 Phone, constitui um desafio particularmente interessante para quem tem experiência profissional nas duas áreas. A domótica surgiu na década de 70 como uma aplicação da eletrónica e das tecnologias da informação às instalações residenciais, comerciais e industriais. Esta nova área desencadeou uma revolução, não só, ao nível da produção e comercialização, mas, também, do ponto de vista do utilizador, ao promover a comodidade, segurança, personalização e o controlo de pessoas e bens. Os smartphones e tablets vieram permitir que o desenvolvimento de aplicações móveis de interacção com os sistemas domóticos. Ao longo desta dissertação são descritas e analisadas as múltiplas áreas de intervenção da domótica assim como as diferentes tecnologias de aplicação e mercados. Também são analisados os sistemas operativos que existentes, as respetivas cotas de mercado e os tipos de dispositivos disponíveis. Por último, a aplicação foi concebida, implementada e testada para verificar a correcta interacção com o sistema domótico KNX e as funcionalidades de controlo da instalação domótica.

Sistema de localização de veículos para smartphone android

Atualmente os sistemas Automatic Vehicle Location (AVL) fazem parte do dia-a-dia de muitas empresas. Esta tecnologia tem evoluído significativamente ao longo da última década, tornando-se mais acessível e fácil de utilizar. Este trabalho consiste no desenvolvimento de um sistema de localização de veículos para smartphone Android. Para tal, foram desenvolvidas duas aplicações: uma aplicação de localização para smarphone Android e uma aplicação WEB de monitorização. A aplicação de localização permite a recolha de dados de localização GPS e estabelecer uma rede piconet Bluetooth, admitindo assim a comunicação simultânea com a unidade de controlo de um veículo (ECU) através de um adaptador OBDII/Bluetooth e com até sete sensores/dispositivos Bluetooth que podem ser instalados no veículo. Os dados recolhidos pela aplicação Android são enviados periodicamente (intervalo de tempo definido pelo utilizador) para um servidor Web No que diz respeito à aplicação WEB desenvolvida, esta permite a um gestor de frota efetuar a monitorização dos veículos em circulação/registados no sistema, podendo visualizar a posição geográfica dos mesmos num mapa interativo (Google Maps), dados do veículo (OBDII) e sensores/dispositivos Bluetooth para cada localização enviada pela aplicação Android. O sistema desenvolvido funciona tal como esperado. A aplicação Android foi testada inúmeras vezes e a diferentes velocidades do veículo, podendo inclusive funcionar em dois modos distintos: data logger e data pusher, consoante o estado da ligação à Internet do smartphone. Os sistemas de localização baseados em smartphone possuem vantagens relativamente aos sistemas convencionais, nomeadamente a portabilidade, facilidade de instalação e baixo custo.

Conception de microARNs pour attenuer l'expression de genes

Les microARNs appartiennent à la famille des petits ARNs non-codants et agissent comme inhibiteurs des ARN messagers et/ou de leurs produits protéiques. Les mi- croARNs sont différents des petits ARNs interférants (siARN) car ils atténuent l’ex- pression au lieu de l’éliminer. Dans les dernières années, de nombreux microARNs et leurs cibles ont été découverts chez les mammifères et les plantes. La bioinforma- tique joue un rôle important dans ce domaine, et des programmes informatiques de découvertes de cibles ont été mis à la disposition de la communauté scientifique. Les microARNs peuvent réguler chacun des centaines de gènes, et les profils d’expression de ces derniers peuvent servir comme classificateurs de certains cancers. La modélisation des microARNs artificiels est donc justifiable, où l’un pourrait cibler des oncogènes surexprimés et promouvoir une prolifération de cellules en santé. Un outil pour créer des microARNs artificiels, nommé MultiTar V1.0, a été créé et est disponible comme application web. L’outil se base sur des propriétés structurelles et biochimiques des microARNs et utilise la recherche tabou, une métaheuristique. Il est démontré que des microARNs conçus in-silico peuvent avoir des effets lorsque testés in-vitro. Les sé- quences 3’UTR des gènes E2F1, E2F2 et E2F3 ont été soumises en entrée au programme MultiTar, et les microARNs prédits ont ensuite été testés avec des essais luciférases, des western blots et des courbes de croissance cellulaire. Au moins un microARN artificiel est capable de réguler les trois gènes par essais luciférases, et chacun des microARNs a pu réguler l’expression de E2F1 et E2F2 dans les western blots. Les courbes de crois- sance démontrent que chacun des microARNs interfère avec la croissance cellulaire. Ces résultats ouvrent de nouvelles portes vers des possibilités thérapeutiques.

Dynamic Injection of Scribble Features into Graphical Diagram Editors

Almost everyone sketches. People use sketches day in and day out in many different and heterogeneous fields, to share their thoughts and clarify ambiguous interpretations, for example. The media used to sketch varies from analog tools like flipcharts to digital tools like smartboards. Whereas analog tools are usually affected by insufficient editing capabilities like cut/copy/paste, digital tools greatly support these scenarios. Digital tools can be grouped into informal and formal tools. Informal tools can be understood as simple drawing environments, whereas formal tools offer sophisticated support to create, optimize and validate diagrams of a certain application domain. Most digital formal tools force users to stick to a concrete syntax and editing workflow, limiting the user’s creativity. For that reason, a lot of people first sketch their ideas using the flexibility of analog or digital informal tools. Subsequently, the sketch is "portrayed" in an appropriate digital formal tool. This work presents Scribble, a highly configurable and extensible sketching framework which allows to dynamically inject sketching features into existing graphical diagram editors, based on Eclipse GEF. This allows to combine the flexibility of informal tools with the power of formal tools without any effort. No additional code is required to augment a GEF editor with sophisticated sketching features. Scribble recognizes drawn elements as well as handwritten text and automatically generates the corresponding domain elements. A local training data library is created dynamically by incrementally learning shapes, drawn by the user. Training data can be shared with others using the WebScribble web application which has been created as part of this work.

Analysis and regeneration of hypermedia contents through Java and XML tools

This paper presents a tool for the analysis and regeneration of Web contents, implemented through XML and Java. At the moment, the Web content delivery from server to clients is carried out without taking into account clients' characteristics. Heterogeneous and diverse characteristics, such as user's preferences, different capacities of the client's devices, different types of access, state of the network and current load on the server, directly affect the behavior of Web services. On the other hand, the growing use of multimedia objects in the design of Web contents is made without taking into account this diversity and heterogeneity. It affects, even more, the appropriate content delivery. Thus, the objective of the presented tool is the treatment of Web pages taking into account the mentioned heterogeneity and adapting contents in order to improve the performance on the Web
