One of the main challenges in intelligent environments is to correctly model and ascertain the users' behavior in order to react to it and cater to their needs. One of the main challenges in human behavior modeling is predicting the users' next actions. In this paper we propose using two different quantum computing algorithms in order to predict human behavior: Quantum Kernel Alignment and Quantum Support Vector Machines. Our experiments show that those algorithms outperform other traditional machine learning algorithms in this task. We also present a study that analyzes the influence of qubit noise in the performance of the quantum approach. This helps to understand how the accuracy of the quantum computing algorithms will increase as the underlying hardware matures and qubit noise is reduced.}, booktitle = {Proceedings of the 7th {International} {Conference} on {Smart} and {Sustainable} {Technologies} ({Splitech} 2022)}, publisher = {FESB, University of Spli}, author = {Huerga, \xc1lvaro and Almeida, Aitor and Lago, Ana Bel\xe9n and Aguilera, Unai}, month = apr, year = {2022}, keywords = {AI for health, activity recognition, artificial intelligence, behavior, behavior modelling, behavior prediction, futuraal, intelligent environments, machine learning, quantek, quantum computing, wos}, } "]

One of the disadvantages of this fast evolution is that not all users have been used to this new technologies, basically because the way of doing a task has drastically changed. This problem is known as \u201cincrease of the technological or digital gap\u201d. In order to reduce this technological gap we have designed, implemented and evaluated a new Virtual Learning Environment (VLE) based on digital pens. This solution consists of the integration of typical devices with a Learning Management System (LMS), concretely, Google Apps. A digital pen looks and feels like a normal ballpoint pen but thanks to it the handwriting can be captured, stored and sent by a safe way. In this case these data are sent to the LMS where students can manage and share notes by this platform and complete an existing document in the LMS with the digitalized information. The platform also offers a way to evaluate the students. Students can do several tests created by teachers previously. To carry out this activity, students will use a digital pen. Thus, the digitized information with the answers of the students will send to the platform where the tests are corrected immediately.}, booktitle = {{ICERI}2011 {Proceedings}}, author = {Lago, Ana B. and Pretel, Ivan and Zabaleta, Koldo}, year = {2011}, keywords = {digital pen, learning management systems, technological gap}, pages = {5563--5568} }']

While this problem can be addressed at various levels (e.g. device, operating system, middleware, application), we think that it is possible to get a higher energy savings when considering the needs of the applications (application-aware). Our approach is centred on analyzing the behaviour of the applications more than the resources. In this paper, we present an application-aware framework which utilizes the needs of the applications and Dynamic Power Management (DPM) techniques focused on the wireless network card to control and reduce power consumption at runtime. We include a novel technique that increases the energy savings. The experimental results show that the proposed approach achieves up to 75.1\\% average reduction in the energy consumed by the wireless network interface}, booktitle = {Proceedings of the {Fourth} {International} {ICST} {Conference} on {COMmunication} {System} {softWAre} and {middlewaRE}}, author = {Lago, Ana B. and Larizgoitia, Iker}, year = {2009}, keywords = {power management}, pages = {11} }']
