But managing this considerable number of devices and deploying workloads on them in a coordinated and intelligent manner remains a challenge nowadays. In this paper, we focus on introducing the resilience dimension into these deployments, and we provide two main contributions: the use of federated machine learning techniques to develop a collaborative tool between the different devices aimed at detecting the possibility of a device failure, and subsequently, the utilization of the inferred information to optimize deployment plans ensuring the resilience in the devices. These two advances are implemented in an intelligent system, Akats, whose architecture is described in detail in this article. Finally, an application scenario is presented, based on Industry 4.0 - Machine predictive maintenance, to exemplify the benefits of the proposed intelligent system.}, booktitle = {2023 8th {International} {Conference} on {Smart} and {Sustainable} {Technologies} ({SpliTech})}, author = {Diaz-de-Arcaya, Josu and Torre-Bastida, Ana I. and Bonilla, Lander and L\xf3pez-de-Armentia, Juan and Mi\xf1\xf3n, Ra\xfal and Zarate, Gorka and Almeida, Aitor}, month = jun, year = {2023}, keywords = {AIOps, Collaborative tools, Computer architecture, Edge Computing, FML, Federated Machine Learning, Fourth Industrial Revolution, Games, Intelligent systems, Internet of Things, Machine learning, Optimization}, pages = {1--4}, } ']

People in their workplaces do not receive energy consumption feedback nor do they pay a monthly invoice to electricity providers. In order to enhance workers' energy awareness, we have transformed everyday shared electrical appliances which are placed in common spaces (e.g. beamer projectors, coffee-makers, printers, screens, portable fans, kettles, and so on.) into persuasive eco-aware everyday things. The proposed approach lets these appliances report their usage patterns to a Cloud-server where the data is transformed into time-series and then processed to obtain the appliances' next-week usage forecast. Autoregressive Integrated Moving Average (ARIMA) model has been selected as the potentially most accurate method for processing such usage predictions when compared with the performance exhibited by three different configurations of Artificial Neural Networks (ANNs). Our major contribution is the application of soft computing techniques to the field of sustainable persuasive technologies. Thus, consumption predictions are used to trigger timely persuasive interactions to help devices users to operate the appliances as efficiently, energy-wise, as possible. Qualitative and quantitative results were gathered in a between-three-groups study related with the use of shared electrical coffee-makers at workplace. The goal of these studies was to assess the effectiveness of the proposed eco-aware design in a workplace environment in terms of energy saving and the degree of affiliation between people and the smart appliances to create a green-team relationship.}, language = {English}, number = {5}, journal = {Soft Computing Journal.

The workplace is a challenging scenario since the economic incentives are not present to increase energy awareness. To tackle some of these issues we have augmented a shared coffee-maker with eco-feedback to turn it into a green ally of the workers. Its design rationale is twofold: Firstly, to make the coffee-maker able to learn its own usage pattern. Secondly, to communicate persuasively and in real-time to users whether it is more efficient to leave the appliance on or off during certain periods of time along the workday. The goal is to explore a human-machine team towards energy efficiency and awareness, i.e. whether giving the initiative to users to decide how to operate the common appliances, but being assisted by them, is a better choice than automation or mere informative eco-feedback.}, language = {en}, urldate = {2014-05-08TZ}, booktitle = {Extended {Abstracts} on {Human} {Factors} in {Computing} {Systems} ({CHI} 2014)}, publisher = {ACM New York, NY, USA \xa92014}, author = {Casado-Mansilla, Diego and Lopez-de-Armentia, Juan and Garaizar, Pablo and L\xf3pez-de-Ipi\xf1a, Diego}, year = {2014}, keywords = {Eco-aware Everyday Things, Energy-efficiency, Persuasive Technology, Sustainability, eco-feedback, linked-data-social-coffee-maker}, pages = {2425--2430} }']

This produces tons of unnecessary CO\\_2 emissions. This is partly due to the inadequate use of electrical devices given the intangible and invisible nature of energy. This misuse of devices and energy unawareness is particularly relevant in public spaces (offices, schools, hospitals and so on), where people use electrical appliances, but they do not directly pay the invoice to energy providers. Embedding intelligence within public, shared appliances, transforming them into Eco-aware things, is valuable to reduce a proportion of the unnecessarily consumed energy. To this end, we present a twofold approach for better energy efficiency in public spaces: 1) informing persuasively to concerned users about the misuse of electronic appliances; 2) Customizing the operating mode of this everyday electrical appliances as a function of their real usage pattern. To back this approach, a capsule-based coffee machine placed in a research laboratory has been augmented. This device is able to continuously collect its usage pattern to offer feedback to coffee consumers about the energy wasting and also, to intelligently adapt its operation to reduce wasted energy. To this aim, several machine learning approaches are compared and evaluated to forecast the next-day device usage.}, number = {1}, journal = {Mobile Information Systems.

The eco-aware everyday things were devised to prevent the waste of energy resources in common areas where people often elude their responsibility about the energy consumption when using appliances of collective use, like printers, coffee makers, beamers and so on. These eco-appliances are able to improve their energy efficiency dynamically adapting their operation according to their usage patterns. This work proposes a further step, also aligned with devices\u05f3 automation, where everyday consumer devices are transformed into collaborative eco-aware everyday things. Taking advantage of the evolution of the Internet towards the Internet of Things and the Web as a universal communication mechanism both among humans-to-things and things-to-things, it is proposed to use Twitter as a communication channel for eco-aware appliances to share their usage patterns. Thus, other newly deployed similar devices in comparable environments can alleviate the cold-start problem, which is common in scenarios where usage learning is needed. To assess the effectiveness of this approach, a collaboration between three of these eco-aware devices has been simulated, giving place, encouragingly, to a higher energy reduction efficiency when compared with non-collaborative objects.}, urldate = {2015-01-07TZ}, journal = {Journal of Network and Computer Applications}, author = {L\xf3pez-de-Armentia, Juan and Casado-Mansilla, Diego and L\xf3pez-de-Ipi\xf1a, Diego}, month = oct, year = {2014}, note = {00000}, keywords = {Coffee machines, Collaborative eco-aware everyday things, Eco-aware everyday things, JCR1.772, Predictive models, Q1, Smart Everyday Objects, energy-efficiency, linked-data-social-coffee-maker, social devices} }']
