Developing hand-worn input and haptic support for real-world target finding

2019

Locating places in cities is typically facilitated by handheld mobile devices, which draw the visual attention of the user on the screen of the device instead of the surroundings. In this research, we aim at strengthening the connection between people and their surroundings through enabling mid-air gestural interaction with real-world landmarks and delivering information through audio to retain users' visual attention on the scene. Recent research on gesture-based and haptic techniques for such purposes has mainly considered handheld devices that eventually direct users' attention back to the devices. We contribute a hand-worn, mid-air gestural interaction design with directional vibrotacti…

An offline partial evaluator for curry programs

2005

Narrowing-driven partial evaluation is a powerful technique for the specialization of functional logic programs. In this paper, we describe the implementation of a narrowing-driven partial evaluator for Curry programs which follows the offline approach to ensuring termination. Although the new partial evaluator is less precise than previous (online) partial evaluators for Curry, it is much faster and, thus, allows the specialization of larger programs.

A risk evaluation framework for the best maintenance strategy: the case of a marine salt manufacture firm

2020

Highlights • This paper proposes a MCDM framework to support risk evaluation for maintenance activities. • The ANP is proposed to select the best maintenance strategy on the basis of real systems’ features. • The ELECTRE III is used to prioritise the main risks related to the interventions of the selected maintenance policy. • The proposed framework is applied to a core subsystem of a real-world marine salt manufacture firm.

MAC Protocols for Wake-up Radio: Principles, Modeling and Performance Analysis

2018

[EN] In wake-up radio (WuR) enabled wireless sensor networks (WSNs), a node triggers a data communication at any time instant by sending a wake-up call (WuC) in an on-demand manner. Such wake-up operations eliminate idle listening and overhearing burden for energy consumption in duty-cycled WSNs. Although WuR exhibits its superiority for light traffic, it is inefficient to handle high traffic load in a network. This paper makes an effort towards improving the performance of WuR under diverse load conditions with a twofold contribution. We first propose three protocols that support variable traffic loads by enabling respectively clear channel assessment (CCA), backoff plus CCA, and adaptive …

Identification of Reading Difficulties by a Digital Game-Based Assessment Technology

2020

Computerized game-based assessment (GBA) system for screening reading difficulties may provide substantial time and cost benefits over traditional paper-and-pencil assessment while providing means also to individually adapt learning content in educational games. To study the reliability and validity of a GBA system to identify struggling readers performing below a standard deviation from mean in paper-and-pencil test either in raw scores and grade-normative scores, a large-scale study with first to fourth grade students ( N = 723) was conducted, where GBA was administrated as a group test by tablet devices. Overall, the results indicated that the GBA can be successfully used to identify st…

Local Feature Selection with Dynamic Integration of Classifiers

2000

Multidimensional data is often feature space heterogeneous so that individual features have unequal importance in different sub areas of the feature space. This motivates to search for a technique that provides a strategic splitting of the instance space being able to identify the best subset of features for each instance to be classified. Our technique applies the wrapper approach where a classification algorithm is used as an evaluation function to differentiate between different feature subsets. In order to make the feature selection local, we apply the recent technique for dynamic integration of classifiers. This allows to determine which classifier and which feature subset should be us…

The Cross-Level Moderation Effect of Resource-Providing Leadership on the Demands—Work Ability Relationship

2021

Employees in female-dominated sectors are exposed to high workloads, emotional job demands, and role ambiguity, and often have insufficient resources to deal with these demands. This imbalance causes strain, threatening employees’ work ability. The aim of this study was to examine whether resource-providing leadership at the workplace level buffers against the negative repercussions of these job demands on work ability. Employees (N = 2383) from 290 work groups across three countries (Germany, Finland, and Sweden) in female-dominated sectors were asked to complete questionnaires in this study. Employees rated their immediate supervisor’s resource-providing leadership and also self-reported …

Évaluer les compétences sociales : référentiel et analyse de questionnaires existants

2020

International audience; L’évaluation des compétences sociales est un enjeu important dans le monde professionnel, de la formation ou de l’éducation. Cet enjeu se situe à différents niveaux : il est nécessaire d’évaluer à la fois pour « diagnostiquer », pour sélectionner un dispositif ou une formation adapté(e) aux besoins des personnes ciblées et/ou pour attester de l’efficacité et de l’efficience d’un programme ou d’une formation. Pour cela, il est important pour les chercheurs et professionnels de disposer d’instruments d’évaluation de ces compétences, présentant de bonnes qualités psychométriques. Ce travail propose un référentiel et une analyse de questionnaires existants, évaluant les …
