EXPERIMENTAL INVESTIGATION OF DILUTE SOLID-LIQUID SUSPENSION IN AN UNBAFFLED STIRRED VESSELS BY A NOVEL PULSED LASER BASED IMAGE ANALYSIS TECHNIQUE

2009

The availability of experimental information on solid distribution inside stirred tanks is a topic of great importance in several industrial applications. The measurement of solid particle distribution in turbulent multiphase flow is not simple and the development of suitable measurement techniques is still in progress. In this work a novel non-intrusive technique for measuring particle concentration fields in solid-liquid systems is employed. The technique makes use of a laser sheet, a high sensitivity digital camera for image acquisition and a Matlab procedure for post-processing the acquired images. Experimental data are here obtained for the case of an unbaffled stirred tank. Stable tor…

EOF-Library: Open-source Elmer FEM and OpenFOAM coupler for electromagnetics and fluid dynamics

2019

EOF-Library is a software that couples Elmer and OpenFOAM simulation packages. It enables efficient internal field interpolation and communication between the finite element and the finite volume frameworks. The coupling of the two packages is based on the Message Passing Interface, which results in low latency, high data bandwidth and parallel scalability. Potential applications are magnetohydrodynamics, convective cooling of electrical devices, industrial plasma physics and microwave heating. In this work we introduce the software and perform interpolation accuracy and parallel scaling tests by sending a known scalar distribution between the two codes. Keywords: Elmer, FEM, OpenFOAM, FVM,…

Preparation of speciality-integrated assignments in informatics study courses at the higher education level

2012

Information and communications technologies today are used in virtually any university course when students prepare their papers. ICT is also needed after people are graduated from university and enter the job market. This author is an instructor in the field of informatics related to health care and social sciences at the Riga Stradins University. In practice, he has found that after completing informatics courses (IC) at the university level, students and practicing specialists at various levels find it hard to decide on what data processing method to use in order to interpret extracted results in the relevant area of specialisation. There are various data processing methods in the litera…

Virtual Hierapolis: tra tecnicismo e realismo

2011

[ES] Una de las principales actividades de la MAIER tiene como objetivo desarrollar una línea de investigación dirigida a la restauración virtual y la reproducción 3D de los antiguos monumentos de la ciudad romana de Hierápolis de Frigia, Turquía. El proyecto, llamado "Virtual Hierápolis, se ha desarrollado gradualmente en las últimas tres temporadas de excavación (años 2007-2009) y ha madurado a partir de las primeras experiencias de la RV aplicada a este sitio en años anteriores. Esta investigación, coordinada por el Director de la misión italiana, prof. F. D'Andria, y llevada a cabo en el Laboratorio de Tecnologías de la Información (ITLab) dell'IBAM-CNR de Lecce (Italia), implica unidad…

Virtual Reality and Games

2018

The concept of Virtual Reality (VR) dates back to around 1930, where different technologies and concepts arise. For instance, in 1929 Edward Link created the Link Trainer (further patented in 1931), reported to be the first example of a commercial flight simulator, being entirely electromechanical. Also, in the 1930s, the visionary, science fiction writer Stanley G. Weinbaum brings a story (Pygmalion’s Spectacles) that introduces the early idea of a pair of goggles that makes the wearer experience a fictional world through holograms, smell, taste, and touch. Weinbaum describes uncanny experiences for those wearing the goggles, aligned with the modern experiences of VR. It is in the mid 1950…

Bathymetry time series using high spatial resolution satellite images

2020

The use of the new generation of remote sensors, such as echo sounders and Global Navigation Satellite System (GNSS) receivers with differential correction installed in a drone, allows the acquisition of high-precision data in areas of shallow water, as in the case of the channel of the Encañizadas in the Mar Menor lagoon. This high precision information is the first step to develop the methodology to monitor the bathymetry of the Mar Menor channels. The use of high spatial resolution satellite images is the solution for monitoring many hydrological changes and it is the basis of the three-dimensional (3D) numerical models used to study transport over time, environmental variability, and wa…

A study of the relationship between regulatory systems, assessment e locomotion, and online learning groups

2011

The present paper examines the relationship between assessment, locomotion and attitudes and learning outcomes in a Computer-supported collaborative learning (CSCL) framework. Results showed that regulatory mode predicted exam marks, numbers of tasks completed, messages sent and attitudes towards the course and the ingroup. The theoretical implications and some reflections about CSCL and Regulatory-mode Theory (RMT) are presented.

Entornos educativos de complicidad en el proceso del proyecto Second Round

2019

INTRODUCCIÓN. La relación que se establece entre una alumna y su profesor durante el proceso de realización de una tesis doctoral suele estar muy mediada por las líneas de trabajo propias del grupo de investigación al que pertenecen. Sin embargo, en ocasiones se dan circunstancias un tanto particulares que convierten esta relación en un campo de experiencias vinculadas al propio diálogo, evolución que va encajando con las fases de la propia tesis. La confianza entre ambos partícipes se renueva en cada paso de la complicidad asumida. MÉTODO. Aquí presentamos un estudio de caso que hemos experimentado conjuntamente, ya que el tema de la tesis de la doctoranda (el proyecto “Second Round”) es p…

RNA-Binding Proteins as Epigenetic Regulators of Brain Functions and Their Involvement in Neurodegeneration.

2022

A central aspect of nervous system development and function is the post-transcriptional regulation of mRNA fate, which implies time- and site-dependent translation, in response to cues originating from cell-to-cell crosstalk. Such events are fundamental for the establishment of brain cell asymmetry, as well as of long-lasting modifications of synapses (long-term potentiation: LTP), responsible for learning, memory, and higher cognitive functions. Post-transcriptional regulation is in turn dependent on RNA-binding proteins that, by recognizing and binding brief RNA sequences, base modifications, or secondary/tertiary structures, are able to control maturation, localization, stability, and tr…
