Applied mathematics concepts Self-learning through the use of short educational videos
2019
It is sometimes difficult for the student to actively participate in the learning process due to the difficulty that teachers find when trying to cover all the contents of a course with sufficient time and attention. This lack of time prevents professors from properly stimulating the student's active participation in class, which is always necessary for achieving a deep and significant learning. The present paper describes a flipped-classroom-based methodology that fosters autonomous learning of applied mathematics contents through the use of short educational videos. The use of on-line media learning resources has dramatically increased in the last decade in higher education, not only unde…

VISUAL VOCABULARY IN BRANDING
2011
Visual vocabulary or visual language is a set of symbols used to describe a system or a process; it refers to all graphical representations that supplement a brand image, a logo, and build a brand identity that is bound to remain invariable even when the sign undergoes fundamental changes. The article is a presentation of the concept of visual vocabulary/language and of its relevance to branding and marketing. We argue that these symbols are culturally dependent and a key element in brand design.
Study of drilling and welding laser : dynamics of keyhole
2011
The aim of the present work is to study experimentally the formation of the capillary during the drilling and welding by laser beam and to develop the numerical simulation which allows following the dynamics and the evolution of the keyhole. The zinc was chosen as a test material because its thermodynamical properties are well known. To simplify the problem, in the first place the drilling mechanism was studied. Two experimental methods were used to characterize the evolution of the keyhole: the Direct Observation of Drilled Hole method, which allows the visualization of the keyhole after the application of laser pulses of different durations, and Zn-Quartz method, which allows the direct o…
Repensando narrativas na produção audiovisual: E roubaram a África de mim
2015
A proposta pedagógica aqui apresentada tem a ver com o projeto de criação de uma narrativa audiovisual, cujo objetivo principal foi fomentar a reflexão e permitir aos participantes repensar as narrativas na produção audiovisual por meio da abertura e do incremento de caminhos interpretativos possíveis. A narrativa foi produzida por meio do trabalho colaborativo entre dois tipos de participantes: uns com formação literária e outros com formação audiovisual. O produto desse trabalho colaborativo multidisciplinar foi um projeto muito enriquecedor que mostrou negociações no espaço e que, ao mesmo tempo, foi o resultado das negociações dos próprios autores quanto ao processo criativo.
La docencia universitaria del estudio de la imagen: Los talleres de cultura visual y Seminarios de visualidad artística contemporánea
2022
El texto desarrolla la propuesta de innovación educativa que competea los «Talleres de Cultura visual»y los «Seminarios de visualidad artística contemporánea»que se presentan como actividades colaborativas y complementarias en la docencia de la asignatura de «Análisis e interpretación de la imagen»de la Universitat de Valènciadesde el curso 2009-2010. La experiencia de la docencia universitaria en un módulode formación básica,centrado en el estudio de la imagen nos ha permitido implementar dichas modalidades organizativas como óptimas para alcanzar las competencias que se han definido en el proceso de enseñanza/aprendizaje de los alumnos de primer curso de los grados de Historia e Historia …
Behavior in compression of concrete cylinders externally wrapped with basalt fibers
2015
Abstract This paper gives additional information on the use of new class of composites constituted by Basalt Fiber Reinforced Polymer (BFRP) bonded with epoxy resin to concrete specimens as an alternative confinement material for compressed concrete members with respect to carbon or glass fibers. From the experimental point of view, concrete cylinders are wrapped with continuous fibers, in the form of sheets, applying both full and partial discrete wrapping with BFRP straps, and then tested in compression. For comparison, few other concrete cylinders are wrapped with Carbon Fiber Reinforced Polymer (CFRP) sheets and tested in compression. The number and type of plies (full or partial wrappi…
Chemical-state analyses of Ni, Zn, and W ions in NiWO$_4$-ZnWO$_4$ solid solutions by X-ray photoelectron spectroscopy
2022
The chemical states of Ni, Zn, and W in microcrystalline NiWO$_4$-ZnWO$_4$ solid solutions were studied by X-ray photoelectron spectroscopy. The recorded spectra of the Ni 2p, Zn 2p, and W 4f photoelectron lines and Ni L$_2$M$_{23}$M$_{45}$, Zn L$_3$M$_{45}$M$_{45}$, and W N$_4$N$_{67}$N$_{7}$ Auger-transition lines show pronounced changes with increasing Zn concentration. The positions of the resolved photoelectron and Auger-transition lines were combined to construct so-called chemical-state plots (Wagner or Auger-parameter plots) for metal ions in solid solutions. With increasing Zn concentration, the Auger parameter increases for Ni and decreases for W, thus evidencing a lowering and an…
Multiply charged metal cluster anions
2000
Formation, stability patterns, and decay channels of silver dianionic and gold trianionic clusters are investigated with Penning-trap experiments and a shell-correction method including shape deformations. The theoretical predictions pertaining to the appearance sizes and electronic shell effects are in remarkable agreement with the experiments. Decay of the multiply anionic clusters occurs predominantly by electron tunneling through a Coulomb barrier, rather than via fission, leading to appearance sizes unrelated to those of multiply cationic clusters.
Relation between deformation and polarization in the region of diffused phase transition of plzt 8/65/35
1995
Abstract The deformation as a function of polarization was measured in PLZT 8-10/65/35 in the region of diffused phase transition. A different behaviour of deformation in the region of double hysteresis loops was observed corresponding to ferroelectric and nonpolar phases as well as to the field induced phase transition region. In the ferroelectric phase the results are described by electrostriction. The decrease of volume as well as small longitudinal deformations at the field induced transition to ferroelectric state are explained by large remanent deformations, existing in the nonpolar phase. Since description of deformation in the framework of electrostriction cannot be motivated in the…
