About

I am a full-time PhD student at the MAP-i Doctoral Program in Computer Science held by the Universities of Minho, Porto and Aveiro, Portugal. The title of my PhD thesis is “A Virtual Factory for Smart City Service Integration”. The aim of the thesis is to advance the state of the art in software modelling and development tools for the rapid development of integrated city-level electronic public services.

I have a Licenciado degree in Computer Science from Universidad Nacional del Sur, Argentina. The title of my thesis is "Implementation of Autonomous Agents for Real-Time Scenarios Using Defeasible Logic as Knowledge Base".

My current research interests include: modeling and verification of software product lines; workflow specification, integration and verification; and all of them applied to e-governance.

Abstract
VirtuosoNext TM is a distributed real-time operating system (RTOS) featuring a generic programming model dubbed Interacting Entities. This paper focuses on these interactions, implemented as so-called Hubs. Hubs act as synchronisation and communication mechanisms between the application tasks and implement the services provided by the kernel as a kind of Guarded Protected Action with a well defined semantics. While the kernel provides the most basic services, each carefully designed, tested and optimised, tasks are limited to this handful of basic hubs, leaving the development of more complex synchronization and communication mechanisms up to application specific implementations. In this work we investigate how to support a programming paradigm to compositionally build new services, using notions borrowed from the Reo coordination language, and relieving tasks from coordination aspects while delegating them to the hubs. We formalise the semantics of hubs using an automata model, identify the behaviour of existing hubs, and propose an approach to build new hubs by composing simpler ones. We also provide tools and methods to analyse and simplify hubs under our automata interpretation. In a first experiment several hub interactions are combined into a single more complex hub, which raises the level of abstraction and contributes to a higher productivity for the programmer. Finally, we investigate the impact on the performance by comparing different implementations on an embedded board. © IFIP International Federation for Information Processing 2019.
