The proposed layout design synthesizes refocusing slices directly from micro images by omitting the process for the commonly used sub-aperture extraction. Therefore, intellectual property cores, containing switch controlled Finite Impulse Response (FIR) filters, are developed and applied to the Field Programmable Gate Array (FPGA) XC6SLX45 from Xilinx. Enabling the hardware design to work economically, the FIR filters are composed of stored product as well as upsampling and interpolation techniques in order to achieve an ideal relation between image resolution, delay time, power consumption and the demand of logic gates. The video output is transmitted via High-Definition Multimedia Interface (HDMI) with a resolution of 720p at a frame rate of 60 fps conforming to the HD ready standard. Examples of the synthesized refocusing slices are presented

Company-university collaboration in applying gamification to learning about insurance

Incorporating gamification into training–learning at universities is hampered by a shortage of quality, adapted educational video games. Large companies are leading in the creation of educational video games for their internal training or to enhance their public image and universities can benefit from collaborating. The aim of this research is to evaluate, both objectively and subjectively, the potential of the simulation game BugaMAP (developed by the MAPFRE Foundation) for university teaching about insurance. To this end, we have assessed both the game itself and the experience of using the game as perceived by 142 economics students from various degree plans and courses at the University of Seville during the 2017–2018 academic year. As a methodology, a checklist of gamification components is used for the objective evaluation, and an opinion questionnaire on the game experience is used for the subjective evaluation. Among the results several findings stand out. One is the high satisfaction of the students with the knowledge acquired using fun and social interaction. Another is that the role of the university professors and the company monitors turns out to be very active and necessary during the game-learning sessions. Finally, in addition to the benefits to the university of occasionally available quality games to accelerate student skills training, the company–university collaboration serves as a trial and refinement of innovative tools for game-based learning

How triathletes mount their bikes after first transition (T1). A proposal of classification

A proposal is submit for the classification referring to the different ways in which triathletes mount their bikes to start pedalling. This action happens at the end of the transition area (T1) after having gone across on foot, with the bikes at their side, or, led across by hand, in a specific way (Fernández, Romero, Merino and April, 2015). These are unique aspects of this sport, compared to other sports in which a bike is also used. The purpose of this research was concentrates in describing and classifying the motor behaviours that occur at the end of the transition area, in front of the “judge’s line”. This study was bassed on participants of 3 Spanish Elite Championships of different distances (407 triathletes). It was filmed in the moment when they picked up their bikes, passed through the transition area and mounted their bikes. Eleven different ways were discovered on how to mount a bike when passing the judge’s line.Universidad de Málaga. Campus de Excelencia Internacional Andalucía Tec

Electrorotation of semiconducting microspheres

We study experimentally the electrorotation (ROT) of semiconducting microspheres. ZnO microspheres obtained by a hydrothermal synthesis method are dispersed in KCl aqueous solutions and subjected to rotating electric fields. Two ROT peaks are found in experiments: a counterfield peak and a cofield peak at somewhat higher frequencies. These observations are in accordance with recent theoretical predictions for semiconducting spheres. The counterfield rotation is originated by the charging of the electrical double layer at the particle-electrolyte interface, while the cofield rotation is due to the Maxwell-Wagner relaxation. Additionally, we also found that some microspheres in the sample behaved differently and only showed counterfield rotation. We show that the behavior of these particles can be described by the so-called shell model. The microstructure of the microspheres is analyzed with electron microscope techniques and related to the ROT measurements.Spanish Government Ministry MICINN under Contract No. PGC2018-099217-B-I00Junta de Andalucía Contract No. PEJUS-

El método del proyecto en los estudios de grado en Comunicación Audiovisual. El Festival de Cortos AdN como ejemplo aglutinador de competencias.

This article reflects on learning through projects such as teaching strategy in the studies of the degree in Audiovisual Communication, through the course of an activity, until now extra-curricular: Festival de Cortometrajes AdN, at the University of Nebrija in Madrid. Through these lines, will attempt to determine whether it is a successful formula for obtaining the skills required for a graduate or graduate in Audiovisual Communication and the incorporation of it within the curriculum in current curricula.En este artículo se reflexiona sobre el aprendizaje mediante proyectos como estrategia de enseñanza en los estudios de grado en Comunicación Audiovisual, a través del recorrido de una actividad, hasta ahora extra-curricular: el Festival de Cortometrajes AdN, en la universidad Nebrija de Madrid. A través de estas líneas se intentará determinar si es una fórmula de éxito para la obtención de las competencias exigidas para un graduado o graduada en Comunicación Audiovisual y de la incorporación del mismo dentro de la malla curricular en los actuales planes de estudio

Liria XIIC : ¿un kálathos ibérico dedicado a Proserpina?

This paper's purpose is to give a likely explanation of an iberian inscription. Evidence is presented to show that there is a native transcription of the name of a well known latin goddess: Proserpina. Probably it must be read baserbina. The previous word is even possible to refer to the resembling hispanic goddess Ataecina. The inscription appears on a "kalathos", shape sacred in the Classical World to Demeter and Kore, and it belongs to a kind of iberian pottery of an acknowledged religious meaning

Determination of storage suitable auto parts for vehicles of high-end in the center of distribution of an importer of spare parts in Bogotá D.C. - Colombia
