Defeasible Description Logics (DDLs) extend Description Logics with defeasible concept inclusions. Reasoning in DDLs often employs rational or relevant closure according to the (propositional) KLM postulates. If in DDLs with quantification a defeasible subsumption relationship holds between concepts, this relationship might also hold if these concepts appear in existential restrictions. Such ne...

Purpose: The paper proposes a research method for measuring strategic interactions between airline joint-venture alliances that compete with each other. Design/Methodology/Approach: proposed is based on the non-cooperative game theory Nash-Cournot equilibrium. It consists in development of model compares economic performance long-haul, intercontinental operations two consecutive scenarios, befo...

A detailed analysis of the radiative and Auger de-excitation channels of K-shell vacancy states in Fe –Fe  has been carried out. Level energies, wavelengths, A-values, Auger rates and fluorescence yields have been calculated for the lowest fine-structure levels populated by photoionization of the ground state of the parent ion. Different branching ratios, namely Kα 2 /Kα 1 , Kβ/Kα, KLM/KLL,...

Producing caption for the deaf and hearing impaired is a labor intensive task. We implemented a software tool, named SmartCaption, for assisting the caption production process using automatic visual detection techniques aimed at reducing the production workload. This paper presents the results of an eye-tracking analysis made on facial regions of interest to understand the nature of the task, n...

This paper aims to present an assessment of the visual demand of typical data entry tasks in two popular navigation systems among iPhone Brazilians users TomTom App and iGO Primo App. Applying the extended KLM technique, the total times to perform the tasks with interruptions were estimated, with which it was possible to evaluate the potential for driver distraction as per criteria established ...

This paper provides a general semantic framework for nonmonotonic reasoning, based on a minimal models semantics on the top of KLM systems for nonmonotonic reasoning. This general framework can be instantiated in order to provide a semantic reconstruction within modal logic of the notion of rational closure, introduced by Lehmann and Magidor. We give two characterizations of rational closure: t...

Abstract How do governments distribute resources across economic sectors during a crisis? And why some receive more than others? The recent COVID-19 pandemic has highlighted the urgency of these questions. In this paper, we explore extent to which political economy perspective can help explain characteristics sector-specific state aid in Netherlands, traditionally corporatist country. While KLM...

Acoustic energy is an often overlooked but increasingly prevalent source of ambient that could be scavenged to power a wide range devices. Piezoelectric materials are used, the tradeoff between acoustic impedance matching and amount ceramic piezoelectric material as active has not previously been investigated. In this work, commercially available 1–3 dice fill composites with various factors (2...

The aviation industry is facing pressure from stakeholders to transform towards greater sustainability. From a managerial and marketing perspective, not only the actual implementation achievements of sustainability measures, but also their communication likely be crucial—and in many cases even legally required. This research evaluates scope corporate social responsibility (CSR) reporting Europe...
