Emotional-BDI agents are BDI agents whose behaviour is guided not only by beliefs, desires and intentions, but also by the role of emotions in reasoning and decision-making. The E BDI logic is a formal system for expressing the concepts of the Emotional-BDI model of agency. In this paper we present an improved version of the E BDI logic and show how it can(More)
Robustness, real-time properties and resource efficiency are key properties to embedded devices of the CPS/IoT era. In this paper we propose a language approach RTFM-core, and show its potential to facilitate the development process and provide highly efficient and statically verifiable implementations. Our programming model is reactive, based on the(More)
This work presents a mechanically verified implementation of an algorithm for deciding regular expression (in-)equivalence within the Coq proof assistant. This algorithm decides regular expression equivalence through an iterated process of testing the equivalence of their partial derivatives and also does not construct the underlying automata. Our(More)
Prey can invest in a variety of defensive traits when balancing risk of predation against that of starvation. What remains unknown is the relative costs of different defensive traits and how prey reconcile investment into these traits when energetically limited. We tested the simple allocation model of prey defense, which predicts an additive effect of(More)
Over the past decades several approaches for schedulability analysis have been proposed for both uni-processor and multi-processor real-time systems. Although different techniques are employed, very little has been put forward in using formal specifications, with the consequent possibility for misinterpretations or ambiguities in the problem statement.(More)
Kleene algebra (KA) is an algebraic system that captures properties of several important structures arising in Computer Science like automata and formal languages, among others. In this paper we present a formalization of regular languages as a KA in the Coq theorem prover. In particular, we describe the implementation of an algorithm for deciding regular(More)
The IEC 61499 standard provides an executable model for distributed control systems in terms of interacting function blocks. However, the current IEC 61499 standard lacks appropriate timing semantics for the specification of timing requirements, reasoning on timing properties at the model level, and for the timing verification of a specific deployment. In(More)
