- A Domain Specific Language for Automotive Systems IntegrationPublication . Oliveira, Renato; Pereira, David; Maia, Cláudio; Santos, PedroDeveloping complex safe and secure Cyber-Physical Systems (CPS) applications for the automotive domain is typically a complex task, due to the criticality inherent to this domain. Considering such known complexity of the development process, we propose a novel solution that aims to provide a quasiautomatic1 integration process between the different components of such CPS systems via the support of a Domain Specific Language (DSL) that provides several views of the system, abstracting away the more technical implementation details, while imposing system properties and restrictions that have the potential to be formally verified (either statically or at run-time) during design, and facilitates the process of customization and quasi-automatic build and deployment processes. In this paper, we briefly analyze the tools that are available and that cover partially the characteristics of our envisioned DSL, describe its building blocks, and show how it can be applied in a small, yet sufficiently complex CPS application whose architecture is very close to what we may expect for the modern and future generation of CPS application in the automotive domain.
- Programação musical e multimédiaPublication . Santos, Pedro[...] Para o presente documento, decidi eleger e concentrar-me na descrição de uma das áreas de atividade que tenho vindo a desenvolver: a programação audiovisual e multimédia. Isto porque esta é, na minha opinião uma das manifestações mais completas do perfil acima mencionado, por permitir muitas vezes a fusão dos sentidos auditivo e visual, e aliar de uma forma equilibrada a competência técnica ao propósito artístico. De seguida descrevo e reflito acerca de alguns dos projetos realizados neste âmbito. Apesar de alguma desta atividade não ser de caráter profissional num sentido estrito de ser realizada enquanto profissão, que implique necessariamente uma retribuição económica, é-o certamente no sentido de adequadamente assegurar a concretização de um trabalho que requeira conhecimentos formais e competências práticas especializadas.
- Simulation Module and Tools for XDense Sensor NetworkPublication . Loureiro, João; Santos, Pedro; Rangarajan, Raghuraman; Tovar, EduardoWe present a NS-3 module developed for wired 2D mesh grid sensor network systems, that resemble Network-on-Chip architectures. It has been designed to enable complex feature extraction from sensed data in realtime with distributed processing. We provide the design specifications, communication and processing delay models and a high level system model for XDense using NS-3. We validate our module by comparing its performance with a hardware implementation.
