Do differences exist between how Engineering and non-Engineering lecturers perceive the importance of teaching competences?
A survey we conducted a few years ago concluded
that higher education teachers should have the following
competences: interpersonal, methodological, communicative, planning and management, teamwork and innovation. The authors of this work belong to the Institute in charge of the lecturer-training program at our university, which is basically a
technical one. In order to improve our training program, we pose the following research questions: What are the competences that lecturers perceive as less important. Do our university teachers (engineering teachers) have a different perception of the importance of the different lecturer competences compared to that of other teachers? The results we present in this paper come from a survey that was sent to a total of 15,209 teachers belonging to public universities in our community, and we received a total of 2,347 valid answers. As a result of this study,
we found which competences are those with a significantly bad rating by lecturers in general, and our lecturers in particular. We analyze what measures should be introduce into our teacher training program.Postprint (author's final draft
La Revista del Guadalete (1858-1862). Su contexto y sus texto
En el presente artículo hemos intentado comentar los aspectos más destacables de la Revista del Guadalete (publicada en Jerez de la Frontera entre los años 1858 y 1862). Podemos destacar el contexto histórico, el comentdrío de la importante figura del editor, las diferentes publicaciones consultadas por el susodicho, las dos grandes líneas editoriales (dogmática y crítica) y la reseña de los columnistas más destacados. Aunque no se comentan todos los articulistas dignos de mención, sí están presentes aquellos que dejan una huella indeleble en el lector de la publicació
Hypogravity research and educational parabolic flight activities conducted in Barcelona: a new Hub of innovation in Europe
We report on different research and educational activities related to parabolic flights conducted in Barcelona since 2008. We use a CAP10B single-engine aerobatic aircraft flying out of Sabadell Airport and operating in visual flight conditions providing up to 8 seconds of hypogravity for each parabola. Aside from biomedical experiments being conducted, different student teams have flown in parabolic flights in the framework of the international contest ‘Barcelona Zero-G Challenge’, and have published their results in relevant symposiums and scientific journals. The platform can certainly be a good testbed for a proof-of-concept before accessing other microgravity platforms, and has proved to be excellent for motivational student campaigns.Peer ReviewedPostprint (author's final draft
Si elimino el examen, ¿cómo evalúo?: Una discusión sobre las actividades sustitutivas del examen y su escalabilidad
Se ha discutido mucho sobre los inconvenientes de los exámenes, siendo criticados en ocasiones por fomentar el aprendizaje superficial. Aunque muchos profesores estemos de acuerdo, nos preguntamos ¿por qué actividades se pueden sustituir? Existen experiencias para eliminar el uso de exámenes, pero la mayoría son criticadas por realizarse sobre grupos pequeños con muchas actividades evaluadoras. Este trabajo presenta diversas estrategias y actividades realizadas en una asignatura del grado de Informática para poder eliminar los exámenes consiguiendo al mismo tiempo un alto nivel de aprendizaje. La experiencia se ha realizado sobre un grupo pequeño, pero ante la presión de nuestro centro por aumentar la matrícula, se están diseñando las actividades para seguir garantizando una buena experiencia educativa sin incrementar el trabajo del profesor.Peer ReviewedPostprint (published version
New characterizations of ruled real hypersurfaces in complex projective space
We consider real hypersurfaces M in complex projective space equipped with both the Levi–Civita and generalized Tanaka–Webster connections. For any nonnull constant k and any symmetric tensor field of type (1, 1) L on M, we can define two tensor fields of type (1, 2) on M, LF(k) and LT(k) , related to both connections. We study the behaviour of the structure operator ϕ with respect to such tensor fields in the particular case of L= A , the shape operator of M, and obtain some new characterizations of ruled real hypersurfaces in complex projective space.MICINN Project PID 2020-116126GB-100Junta de Andalucía Project PY20-0139Universidad de Granada/CBU
New results on derivatives of the shape operator of a real hypersurface in a complex projective space
This work was supported by MINECO-FEDER Project MTM 2016-78807-C2-1-P.We consider real hypersurfaces M in complex projective space equipped with both the Levi-Civita and
generalized Tanaka-Webster connections. For any nonnull real number k and any symmetric tensor field of type (1,1)
L on M we can define a tensor field of type (1,2) on M, L(k)

skewsymmetry of the tensor A(k)
F associated to the shape operatorA of M.MINECO-FEDER Project MTM 2016-78807-C2-1-
Lie Derivatives of the Shape Operator of a Real Hypersurface in a Complex Projective Space
This work was supported by MINECO-FEDER Project MTM 2016-78807-C2-1-P.We consider real hypersurfaces M in complex projective space
equipped with both the Levi-Civita and generalized Tanaka–Webster
connections. Associated with the generalized Tanaka–Webster connection
we can define a differential operator of first order. For any nonnull
real number k and any symmetric tensor field of type (1,1) B on M,
we can define a tensor field of type (1,2) on M, B(k)
T , related to Lie derivative
and such a differential operator. We study symmetry and skew
symmetry of the tensor A(k)
T associated with the shape operator A of
M.MINECO-FEDER Project MTM 2016-78807-C2-1-
Some Conditions Concerning the Shape Operator of a Real Hypersurface in Complex Projective Space
Funding for open access publishing: Universidad de Granada/CBUA Funding for open access
charge: Universidad de Granada/CBUA.Let M be a real hypersurface of a complex projective space. For any operator B on M and any nonnull real number k, we can define two tensor fields of type (1,2) on M, BF(k) and BT(k) . We will classify real hypersurfaces in complex projective space for which BF(k) and BT(k) either take values in the maximal holomorphic distribution D or are parallel to the structure vector field ξ , in the particular case of B= A , where A denotes the shape operator of M. We also introduce the concept of AF(k) and AT(k) being D -recurrent and classify real hypersurfaces such that either AF(k) or AT(k) are D -recurrent.MICINN: PID 2020-116126GB-I00Universidad de Granada/CBU
Numerical dynamic analysis of reciprocating compressor mechanism. Parametric studies for optimization purposes
© 2016. This version is made available under the CC-BY-NC-ND 4.0 license http://creativecommons.org/licenses/by-nc-nd/4.0/A complete numerical dynamic analysis of reciprocating compressor mechanism is presented, coupling the instantaneous pressure in the compression chamber, the electric motor torque and the hydrodynamic reactions, which arise from the piston and crankshaft secondary movements. Additionally, non-constant crankshaft angular velocity and the piston and crankshaft misalignment torques have also been considered. Two sensitivity analyses have been carried out to prove that neither the inertial forces in the directions of the secondary movements, nor the oscillations of the angular velocity produce significant differences in the compressor behaviour. Finally, a set of parametric studies has been developed to evaluate the influence of geometrical parameters in the stability of the secondary movements, the friction power losses and the compressor consumptionPeer ReviewedPostprint (author's final draft
