Designing learning tools in the AI Era: Developing for design science research in PhD education
No full text194 p.Traditional learning theories often view learning as an integrative process where learners must connect new information to their existing knowledge. The increasing presence of Artificial Intelligence (AI) technologies, particularly Large Language Models (LLMs), is transforming the landscape of learning tools by shifting from traditional reading towards interactive prompting techniques. From a learning perspective, doctoral studies differs significantly from previous education due to independent research, creation of new knowledge, and advanced critical thinking, with minimal direct instruction. Moreover, when resorting to Design Science Research (DSR) as methodology, students typically have difficulties in capturing and representing the complexities of practical problems and understanding the opportunities and constraints necessary for impactful contributions to practice.Using Action Design Research (ADR) and guided by a 2x2 classification matrix, which organizes knowledge representation into new information (documents or LLMs) and existing knowledge (text or diagrams), this thesis focuses on supporting three key activities in doctoral studies: knowledge representation, problem scoping, and writing. This thesis resulted in the design of three web extensions: Concept&Go, Chatin, and PrompTeX.This work was hosted by the University of the Basque Country (Faculty of Informatics). The author enjoyed

A Controlled Thermoalgesic Stimulation Device for Exploring Novel Pain Perception Biomarkers
No full textPublisher Copyright: © 2013 IEEE.Objective: To develop a new device for identifying physiological markers of pain perception by reading the brain's electrical activity and hemodynamic interactions while applying thermoalgesic stimulation. Methods: We designed a compact prototype that generates well-controlled thermal stimuli using a computer-driven Peltier cell while simultaneously capturing electroencephalography (EEG) and photoplethysmography (PPG) signals. The study was performed on 35 healthy subjects (mean age 30.46 years, SD 4.93 years; 20 males, 15 females). We first determined the heat pain threshold (HPT) for each subject, defined as the maximum temperature that the subject can withstand when the Peltier cell gradually increased the temperature. Next, we defined the painful condition as the one occurring at temperature equal to 90% of the HPT, comparing this to the no-pain state (control) in the absence of thermoalgesic stimulation. Results: Both the one-dimensional and the two-dimensional spectral entropy (SE) obtained from both the EEG and PPG signals differentiated the condition of pain. In particular, the SE for PPG was significantly reduced in association with pain, while the SE for EEG increased slightly. Moreover, significant discrimination occurred within a specific range of frequencies, 26-30 Hz for EEG and about 5-10 Hz for PPG. Conclusion: Hemodynamics, brain dynamics and their interactions can discriminate thermal pain perception. Significance: The possibility of monitoring on-line variations in thermal pain perception using a similar device and algorithms may be of interest to study different pathologies that affect the peripheral nervous system, such as small fiber neuropathies, fibromyalgia or painful diabetic neuropathy.Manuscript received August 6, 2020; revised March 26, 2021; accepted May 8, 2021.

Model driven product line engineering : core asset and process implications
No full textReuse is at the heart of major improvements in productivity and quality in Software Engineering. Both Model Driven Engineering (MDE) and Software Product Line Engineering (SPLE) are software development paradigms that promote reuse. Specifically, they promote systematic reuse and a departure from craftsmanship towards an industrialization of the software development process. MDE and SPLE have established their benefits separately. Their combination, here called Model Driven Product Line Engineering (MDPLE), gathers together the advantages of both.
Nevertheless, this blending requires MDE to be recasted in SPLE terms. This has implications on both the core assets and the software development process. The challenges are twofold: (i) models become central core assets from which products are obtained and (ii) the software development process needs to cater for the changes that SPLE and MDE introduce. This dissertation proposes a solution to the first challenge following a feature oriented approach, with an emphasis on reuse and early detection of inconsistencies. The second part is dedicated to assembly processes, a clear example of the complexity MDPLE introduces in software development processes. This work advocates for a new discipline inside the general software development process, i.e., the Assembly Plan Management, which raises the abstraction level and increases reuse in such processes. Different case studies illustrate the presented ideas.This work was hosted by the University of the Basque Country (Faculty

Research on Coatings and Infiltration to Strengthen Ceramic Lost Cores Used in High-Pressure Die Casting Processes
No full textPublisher Copyright: © 2019, The Author(s).Lost cores used to manufacture complex aluminium components through high-pressure die casting (HPDC) processes need to withstand very high injection velocities and pressures. The conventional sand cores used in other casting processes, such as sand casting or low-pressure die casting, do not support the aggressive process parameters of the HPDC, so advanced ceramic cores must be used. These cores must be strong enough not to get broken during the casting process, but, at the same time, they must have a minimum porosity to be easily removed from the casting to obtain the finished part. Due to this porosity, the aluminium penetrates the core surface during the casting process. So, the criterion here is to find the necessary compromise between strength and porosity and to protect the core surface from the aluminium penetration. In this work, two research lines have been followed to address these challenges. On the one hand, different refractory coatings have been applied to the ceramic core surface with the aim of sealing it. Amongst the coatings analysed, boron nitride-based one has been found to be the most suitable and cost-effective solution to avoid aluminium penetration. On the other hand, silica has been proved to be a suitable infiltration agent to increase the strength of the core.Peer reviewe

No full textChildhood trauma & our role in its prevention and treatment
No full textEste trabajo de fin de estudios se centra en desarrollar; el trauma, la infancia, y el rol que
jugamos los profesionales educativos en su detección, prevención y tratamiento. Para
completar el marco teórico, nos hemos introducido en tres temas; trauma, atención con
enfoque de trauma, y practicas con enfoque de trauma. En esta parte del trabajo, definimos
y explicamos estos conceptos desde un contexto clínico y educativo, centrandonos
especialmente en los elementos y practicas relevantes con la infancia y/o que puedan ser
llevadas de un contexto a otro. Nos centramos especialmente en el modelo TIPE
(Trauma-Informed Positive Education) para analizar la aplicación de practicas con enfoque
de trauma en el aula, para atender no solo a los alumnos directamente afectados, sino al
grupo en su totalidad. Una vez hecho esto, pasamos a desarrollar la parte práctica, en la
que, basandonos en los datos recabados, proponemos seis estrategias y recursos que los
docentes pueden implementar a nivel de aula en su día a día. Para concluir la sección,
exponemos una situación real en la que por el contexto, la autora pone en practica un
enfoque de trauma en sus interacciones con los alumnos, y posteriormente comenta los
resultados obtenidos.This final dissertation focuses on the development of three topics; trauma, childhood trauma,
and the role of educational professionals in its detection, prevention, and treatment. To
complete the theoretical framework of the paper, we have introduced three themes; trauma,
trauma-informed care, and trauma-informed practices. In this part of the paper, we define
and explain these concepts from a clinical and educational context, focusing especially on
the elements and practices that are relevant to children and/or can be carried over from one
context to the other. We focus especially on the TIPE (Trauma-Informed Positive Education)
model to analyze the application of trauma-informed practices in the classroom, in order to
address not only the students directly affected but the group as a whole. Once this has been
done, we move on to the practical part, in which, based on the data collected, we propose
six strategies and resources that teachers can implement at the classroom level in their
day-to-day work. To conclude the practical framework, we present a real situation in which,
due to the context, the author of the work implements a trauma approach in her interactions
with her students, and then comments on the results obtained.Graduado o Graduada en Maestro en Educación Infantil por la Universidad Pública de NavarraHaur Hezkuntzako Irakasletzan Graduatua Nafarroako Unibertsitate Publikoa
Influence of the slope in percentile estimation through binary regression for dose-finding experiments
No full textDose-finding experiments aim to estimate the dose having a specified proportion of positive responses by collecting data in the vicinity of this unknown target dose. The importance of estimating the slope as well as a target dose has been recognized long ago in the literature. With large slopes at the target dose, a small error in the target dose estimate will be far from the target. Alternatively, with small slopes at the target, a large error conveys negligible changes on the associated response rate. Thus a reasonably reliable estimate of the slope of the response function at the target dose should accompany every reported target dose estimate. Assuming a monotone increasing dose-response relationship, we work with a sizable catalogue of binary location-scale regression models parameterized by the target dose and the slope at the target. A compound design is proposed for the joint estimation of both features.The second author was sponsored by Ministerio de Ciencia e Innovación PID2020-116873GB-I00 and PID2020-114031RB-I00; Spanish National Plan for Scientific and Technical Research and Innovation.

Graphene as Vehicle for Ultrafast Lithium Ion Capacitor Development Based on Recycled Olive Pit Derived Carbons
No full textHerein we report a series of lithium ion capacitors (LICs) with extraordinary energy-to-power ratios based on olive pit recycled carbons and supported on graphene as a conducting matrix. LICs typically present limited energy densities at high power densities due to the sluggish kinetics of the battery-type electrode. To circumvent this limitation, the hard carbon (HC) was embedded in a reduced graphene oxide (rGO) matrix. The addition of rGO into the negative electrode not only forms a 3D interpenetrating carbon network but also wraps HC particles, facilitating ion diffusion and enhancing the electronic conductivity notably at high power densities. Electrochemical impedance spectroscopy (EIS) analysis reveals that charge-transfer resistance at electrode-electrolyte interphase and the charge-transport resistance within the electrode are considerably lower in the presence of rGO. In addition, charge-transport resistance remains constant upon cycling even at increasing current densities. Capacity gain at high current densities, owing to the reduction of the electrode resistance, triggers the overall LIC performance, allowing for the assembly of an ultrafast LIC delivering up to 200 Wh kg(AM)(-1) at low power rates and 100 Wh kg(AM)(-1).
