The generalized H\"older and Morrey-Campanato Dirichlet problems for elliptic systems in the upper-half space

We prove well-posedness results for the Dirichlet problem in $\mathbb{R}^{n}_{+}$ for homogeneous, second order, constant complex coefficient elliptic systems with boundary data in generalized H\"older spaces $\mathscr{C}^{\omega}(\mathbb{R}^{n-1},\mathbb{C}^M)$ and in generalized Morrey-Campanato spaces $\mathscr{E}^{\omega,p}(\mathbb{R}^{n-1},\mathbb{C}^M)$ under certain assumptions on the growth function $\omega$. We also identify a class of growth functions $\omega$ for which $\mathscr{C}^{\omega}(\mathbb{R}^{n-1},\mathbb{C}^M)=\mathscr{E}^{\omega,p}(\mathbb{R}^{n-1},\mathbb{C}^M)$ and for which the aforementioned well-posedness results are equivalent, in the sense that they have the same unique solution, satisfying natural regularity properties and estimates.Comment: Minor correction

Transient Absorption Spectroscopy (TAS) for the study of organic materials for energy conversion

Transient Absorption Spectroscopy (TAS) is a pump probe technique with the ability of directly probe the photogenerated species and their evolution with time. This technique consists in two light sources, one of them generates the photoexcited species while the other one probe those as-generated species. TAS allows to study energy transfer dynamics in a wide range of materials (organic molecules, metal complexes, inorganic materials, etc) in a wide range of media (solution, solid state, etc). Following the School spirit of this ‘Escuela de Materiales Moleculares’ this talk is going to explain the capabilities and functioning of TAS. This will include both, picosecond and microsecond TAS, with their differences in setup and applicability. This talk will focus on the application of this technique in the study of organic materials used to generate energy. Among the variety of the studied examples, there will be small molecules donors, diradicals materials. And the information that TAS is able to obtain from those.RSEQ. Universidad de Málaga.

Triplet-charge annihilation in a small molecule donor: acceptor blend as a major loss mechanism in organic photovoltaics

Resumen comunicación presentadaOrganic photovoltaics (OPV) are close to reaching a landmark 20% device efficiency.[1] One of the proposed reasons that OPVs have yet to attain this milestone is their propensity toward triplet formation. In this talk,[2] the small molecule donor, DRCN5T, is studied using a variety of spectroscopy techniques, and blended with both fullerene and non-fullerene acceptors. Specifically, picosecond and microsecond transient absorption and Raman spectroscopies are focused on. Despite DRCN5T's ability to achieve OPV efficiencies of over 10%,[3] it generates an unusually high population of triplets. These triplets are primarily formed in amorphous regions via back recombination from a charge transfer state. As such, triplets have a dual role in DRCN5T device efficiency suppression: they both hinder free charge carrier formation and annihilate those free charges that do form. Using microsecond transient absorption spectroscopy under oxygen conditions, this triplet-charge annihilation (TCA) is directly observed as a general phenomenon in a variety of DRCN5T: fullerene and non-fullerene blends. Since TCA is usually inferred rather than directly observed, it is demonstrated that this technique is a reliable method to establish the presence of TCA.Universidad de Málaga.

Gait analysis in a box: A system based on magnetometer-free IMUs or clusters of optical markers with automatic event detection

Gait analysis based on full-body motion capture technology (MoCap) can be used in rehabilitation to aid in decision making during treatments or therapies. In order to promote the use of MoCap gait analysis based on inertial measurement units (IMUs) or optical technology, it is necessary to overcome certain limitations, such as the need for magnetically controlled environments, which affect IMU systems, or the need for additional instrumentation to detect gait events, which affects IMUs and optical systems. We present a MoCap gait analysis system called Move Human Sensors (MH), which incorporates proposals to overcome both limitations and can be configured via magnetometer-free IMUs (MH-IMU) or clusters of optical markers (MH-OPT). Using a test–retest reliability experiment with thirty-three healthy subjects (20 men and 13 women, 21.7 ± 2.9 years), we determined the reproducibility of both configurations. The assessment confirmed that the proposals performed adequately and allowed us to establish usage considerations. This study aims to enhance gait analysis in daily clinical practice

Dietary Intervention through Flipped Learning as a Techno Pedagogy for the Promotion of Healthy Eating in Secondary Education

We acknowledge the researchers of the research group AREA (HUM-672), which belongs to the Ministry of Education and Science of the Junta de Andalucía and is registered in the Department of Didactics and School Organization of the Faculty of Education Sciences of the University of Granada.Technological progress in the educational field has led to the application of active and innovative teaching methods, such as flipped learning, including in the field of dietary education. This is considered a mixed formative approach that combines face-to-face and outside the classroom education. The objective of this research was to analyze the effectiveness of flipped learning methodology on a traditional training practice in dietary training, both in the sixth grade of primary education and in the fourth level of secondary education. A quasi-experimental design was adopted with two experimental groups, two control groups and only posttest. The final sample was composed of 115 students divided into four groups, two of each educational stage mentioned. A didactic unit consisting of six sessions in all groups was applied. Two different training methodologies were followed according to the nature of the group (control-traditional; experimental-flipped learning). The results reveal that flipped learning is effective both in primary education and in secondary education, being more influential in student development in this last stage. It is concluded that the flipped learning approach has meant an improvement of the academic indicators evaluated after a diet education program.This research was funded by I+D+I OTRI-Universidad de Granada CNT-4315.

Do Age and Educational Stage Influence No-Mobile-Phone Phobia?

Technological progress not only brings with it resources that improve and facilitate the day-to-day life of the people who make up society but also entails health risks, with the emergence of terms, such as nomophobia, which is considered an anxiety disorder produced by the fear that not having a mobile phone generates in a person. This research aims to identify the relationship and influence between levels of nomophobia and the age or educational stage of students. The research method is based on a correlational and predictive design of quantitative methodology. The instrument used is the NMP-Q questionnaire. The study population is students from different educational stages (obligatory secondary education, baccalaureate, vocational training and university). The results show that students over 12 years old present an average level of “nomophobia” (no-mobile-phone phobia), namely, not being able to communicate with the family where the highest levels are presented. We conclude that students over 12 years of age and of any educational stage present an average level of nomophobia, and it cannot be determined that either the educational stage or the age are determining factors in the presentation of this problem. This can occur at any age and at any level of the different educational stages, although there are risk indicators that we should bear in mind to avoid the appearance of nomophobia.I+D+I Project Research of Results Transfer Office (OTRI) of the University of Granada (Reference: CNT 4439

Gestor de conocimiento: buenas prácticas para estudiantes de la asignatura informática social en la Universidad Católica de Colombia

Práctica SocialLos estudiantes de la asignatura Informática Social del programa de ingeniería de sistemas de la universidad Católica de Colombia se ven enfrentados a temas muy importantes de gran responsabilidad y compromiso tanto social como humano y muchas veces no están asociados o enterados de la relevancia de dicha asignatura. Es cuando se plantea una solución a una problemática o proyecto social cuando se dan cuenta que ésta requiere una gran cantidad de tiempo y compromiso y no es una asignatura complementaria a su carrera profesional. Adicionalmente, cuando los estudiantes ven la asignatura por primera vez no cuentan con las herramientas, guías y bases necesarias para desarrollar un proyecto social de calidad. El profesor de la asignatura no puede estar con todos los grupos y proyectos al mismo tiempo y ellos necesitan desarrollar buenas prácticas para crear, implementar o seguir con un proyecto social ya implementado.PregradoIngeniero de Sistema
