Efficient distributed average consensus in wireless sensor networks
2020
International audience; Computing the distributed average consensus in Wireless Sensor Networks (WSNs) is investigated in this article. This problem, which is both natural and important, plays a significant role in various application fields such as mobile agents and fleet vehicle coordination, network synchronization, distributed voting and decision, load balancing of divisible loads in distributed computing network systems, and so on. By and large, the average consensus' objective is to have all nodes in the network converged to the average value of the initial nodes' measurements based only on local nodes' information states. In this paper, we introduce a fully distributed algorithm to a…
Robust H-Infinity Filter Design for Uncertain Linear Systems Over Network with Network-Induced Delays and Output Quantization
2009
This paper investigates a convex optimization approach to the problem of robust H-Infinity filtering for uncertain linear systems connected over a common digital communication network. We consider the case where quantizers are static and the parameter uncertainties are norm bounded. Firstly, we propose a new model to investigate the effect of both the output quantization levels and the network conditions. Secondly, by introducing a descriptor technique, using Lyapunov-Krasovskii functional and a suitable change of variables, new required sufficient conditions are established in terms of delay-dependent linear matrix inequalities (LMIs) for the existence of the desired network-based quantize…
Organizational performance focused on users' quality of life: The role of service climate and "contribution-to-others" wellbeing beliefs.
2017
The investigation of organizational factors as precursors of the quality of life (QoL) of service users in organizations for individuals with intellectual disability has been relatively neglected.With this in mind, this study tests the mediation of service climate between employee's "contribution-to-others" wellbeing beliefs (COWBs) and organizational performance focused on the QoL of individuals with intellectual disability. A total of 104 organizations participated in the study. Data were collected from 885 employees and 809 family members of individuals with intellectual disability. The results of the multilevel mediation model supported the hypotheses. When employees believe that their …
Attitudes of Undergraduate Nursing Students towards Patient Safety: A Quasi-Experimental Study
2021
Improving nursing students’ attitudes towards patient safety is a current and relevant topic. This study aims to evaluate the effectiveness of an educational intervention based on critical incident and root cause analysis (RCA) techniques regarding attitudes towards patient safety in nursing students. A quasi-experimental before and after study was developed between January 2018 and December 2019 in a sample of 100 nursing students at Universitat Jaume I (Spain). The intervention was developed in two phases. Phase I was at university, where students applied the RCA technique in a real case. Phase II took place during clinical practice. Students used critical incidents to identify a risk sit…
2021
Background: University students encounter various stressors such as exam preparation, workload and economic concerns. Having to deal with a multitude of stressors can lead to mental health problems and have a negative impact on academic outcomes in students attending university. This paper describes the development and usability evaluation of an open and easily accessible online portal (me@JGU) designed to help students build skills they need to cope with common stressors and manage their own mental health. Methods: We developed a website that addresses the most common stressors among university students and offers strategies for dealing with difficult situations. Initial evaluation results…
The attractiveness of narcissists: Hard work or natural beauty?
2019
Are narcissists more attractive and perceived as such? In a preregistered multi-Study project, we aimed at gaining differentiated insights into this classic question, by considering agentic and ant...
Female Cyborgs, Gender Performance, and Utopian Gaze in Alex Garland’s Ex Machina
2020
The cyborg as a metaphor for cultural encodings of the interaction between humans and technology has been an accepted trope since the publication of Donna Haraway’s “Cyborg Manifesto.” Alex Garland’s 2015 film Ex Machina shares many of its key themes and motifs with earlier science fiction films, from Fritz Lang’s Metropolis to Ridley Scott’s Blade Runner. A first viewing of the film thus suggests an interpretation that focuses on the film’s portrayal of its female cyborgs Ava and Kyoko as another version of the “pleasure model” in the mode of Lang’s Maria or Scott’s Pris. However, it is the tension between Ava’s intelligence and visual attractiveness and her performance of a female gender …
Attractive rivals may undermine the expectation of career advancement and enhance jealousy
2016
This experiment with 119 adult females examined the effect of a rival’s attractiveness on jealousy and career advancement expectations in a simulated work setting where individuals had to compete for a job promotion. We hypothesized that an attractive rival would evoke relatively more jealousy and lower career advancement expectations, especially in individuals high in Intrasexual Competitiveness (ISC). In addition, we examined the moderating effects of characteristics attributed to the rival in terms of popularity, professionalism, and unfriendliness. The results showed that, overall, an attractive rival induced more jealousy and lower career advancement expectations than an unattractive r…
2015
Visuo-auditory sensory substitution systems are augmented reality devices that translate a video stream into an audio stream in order to help the blind in daily tasks requiring visuo-spatial information. In this work, we present both a new mobile device and a transcoding method specifically designed to sonify moving objects. Frame differencing is used to extract spatial features from the video stream and two-dimensional spatial information is converted into audio cues using pitch, interaural time difference and interaural level difference. Using numerical methods, we attempt to reconstruct visuo-spatial information based on audio signals generated from various video stimuli. We show that de…
Steered Response Power Localization of Acoustic Passband Signals
2017
The vast majority of localization approaches using phase transform (PHAT) consider that the sources of interest are wideband low-pass sources. While this may be the usual case for common audio signals such as speech, PHAT methods are affected negatively by modulation artifacts when the sources to be localized are passband signals. In these cases, steered response power PHAT localization becomes less robust. This letter analyzes the form of generalized cross-correlation functions with PHAT when passband acoustic signals are considered, proposing approaches for increasing the localization performance through the mitigation of these negative effects.
