Sufficient conditions for local tabularity of a polymodal logic

On relational structures and on polymodal logics, we describe operations which preserve local tabularity. This provides new sufficient semantic and axiomatic conditions for local tabularity of a modal logic. The main results are the following. We show that local tabularity does not depend on reflexivity. Namely, given a class $\mathcal{F}$ of frames, consider the class $\mathcal{F}^\mathrm{r}$ of frames, where the reflexive closure operation was applied to each relation in every frame in $\mathcal{F}$. We show that if the logic of $\mathcal{F}^\mathrm{r}$ is locally tabular, then the logic of $\mathcal{F}$ is locally tabular as well. Then we consider the operation of sum on Kripke frames, where a family of frames-summands is indexed by elements of another frame. We show that if both the logic of indices and the logic of summands are locally tabular, then the logic of corresponding sums is also locally tabular. Finally, using the previous theorem, we describe an operation on logics that preserves local tabularity: we provide a set of formulas such that the extension of the fusion of two canonical locally tabular logics with these formulas is locally tabular

Foundations of Human-Aware Planning -- A Tale of Three Models

abstract: A critical challenge in the design of AI systems that operate with humans in the loop is to be able to model the intentions and capabilities of the humans, as well as their beliefs and expectations of the AI system itself. This allows the AI system to be "human- aware" -- i.e. the human task model enables it to envisage desired roles of the human in joint action, while the human mental model allows it to anticipate how its own actions are perceived from the point of view of the human. In my research, I explore how these concepts of human-awareness manifest themselves in the scope of planning or sequential decision making with humans in the loop. To this end, I will show (1) how the AI agent can leverage the human task model to generate symbiotic behavior; and (2) how the introduction of the human mental model in the deliberative process of the AI agent allows it to generate explanations for a plan or resort to explicable plans when explanations are not desired. The latter is in addition to traditional notions of human-aware planning which typically use the human task model alone and thus enables a new suite of capabilities of a human-aware AI agent. Finally, I will explore how the AI agent can leverage emerging mixed-reality interfaces to realize effective channels of communication with the human in the loop.Dissertation/ThesisDoctoral Dissertation Computer Science 201

TesisSe realizó un análisis clínico-electrocardiográfico integral de los hemibloqueos comprendiendo incidencia, edad, etiología, evaluación cuantitativa de los criterios diagnósticos, relación con los trastornos de conducción aurículo-ventricular, y pronóstico. Con tal motivo se estudiaron 221hemibloqueos encontrados en 7,130 pacientes adultos de sexo masculino en un servicio de cardiología y medicina. Los hemibloqueos fueron diagnosticados mediante los criterios señalados por Rosenbaum, Castellanos, y Prior y Blount
