Finding essential features for tracking starfish in a video sequence

2004

The paper introduces a software system for detecting and tracking starfish in an underwater video sequence. The target of such a system is to help biologists in giving an estimate of the number of starfish present in a particular area of the sea-bottom. The nature of the input images is characterised by a low signal/noise ratio and by the presence of noisy background represented by pebbles; this makes the detection a non-trivial task. The procedure we use is a chain of several steps that starts from the extraction of the area of interest and ends with a classifier and a tracker providing the necessary information for counting the starfish present in the scene. © 2003 IEEE.

The Playing Brain. The Impact of Video Games on Cognition and Behavior in Pediatric Age at the Time of Lockdown: A Systematic Review

2021

A growing number of children and adolescents play video games (VGs) for long amounts of time. The current outbreak of the Coronavirus pandemic has significantly reduced outdoor activities and direct interpersonal relationships. Therefore, a higher use of VGs can become the response to stress and fear of illness. VGs and their practical, academic, vocational and educational implications have become an issue of increasing interest for scholars, parents, teachers, pediatricians and youth public policy makers. The current systematic review aims to identify, in recent literature, the most relevant problems of the complex issue of playing VGs in children and adolescents in order to provide sugges…

Energy Efficiency Evaluation of Dynamic Partial Reconfiguration in Field Programmable Gate Arrays: An Experimental Case Study

2018

Both computational performances and energy efficiency are required for the development of any mobile or embedded information processing system. The Internet of Things (IoT) is the latest evolution of these systems, paving the way for advancements in ubiquitous computing. In a context in which a large amount of data is often analyzed and processed, it is mandatory to adapt node logic and processing capabilities with respect to the available energy resources. This paper investigates under which conditions a partially reconfigurable hardware accelerator can provide energy saving in complex processing tasks. The paper also presents a useful analysis of how the dynamic partial reconfiguration te…

Student-generated instructional videos facilitate learning through positive emotions

2016

The central focus of this study is a learning method in which university students produce instructional videos about the content matter as part of their learning process, combined with other learning assignments. The rationale for this is to promote a more multimodal pedagogy, and to provide students opportunities for a more learner-centred, motivating, active, engaging and productive role in their learning process. As such we designed a ‘video course’ where the students needed to produce an instructional video which could be used for university teaching. In addition to producing the video, the students needed to write a literature review of the topic of the video and a learning journal. At…

Città Invisibili of Teatro Potlach: A Journey to Rediscover Our Cultural Heritage

2017

Città Invisibili is a multidisciplinary art project made by the Italian company Teatro Potlach. Compared to the canonical theatrical performances, Città Invisibili, being in its essence a site-specific performance, interacts with the place where it grows. With the project, the Italian group builds next to the existing space of the place (physical space and memory space) other two spaces, the space of the staging and the space of the performer, using different materials, in particular cloths and video projections. Moreover Teatro Potlach conducts a historical, anthropological and social research trying to bring out the latent memory of places. All these interventions bring out from the place…

Cytochrome c is released in a single step during apoptosis

2005

Release of cytochrome c from mitochondria is a central event in apoptotic signaling. In this study, we utilized a cytochrome c fusion that binds fluorescent biarsenical ligands (cytochrome c-4CYS (cyt. c-4CYS)) as well as cytochrome c-green fluorescent protein (cyt. c-GFP) to measure its release from mitochondria in different cell types during apoptosis. In single cells, the kinetics of cyt. c-4CYS release was indistinguishable from that of cyt. c-GFP in apoptotic cells expressing both molecules. Lowering the temperature by 7 degrees C did not affect this corelease, but further separated cytochrome c release from the subsequent decrease in mitochondrial membrane potential (DeltaPsi(m)). Cyt…

Quantifying Vegetation Biophysical Variables from Imaging Spectroscopy Data: A Review on Retrieval Methods

2019

An unprecedented spectroscopic data stream will soon become available with forthcoming Earth-observing satellite missions equipped with imaging spectroradiometers. This data stream will open up a vast array of opportunities to quantify a diversity of biochemical and structural vegetation properties. The processing requirements for such large data streams require reliable retrieval techniques enabling the spatiotemporally explicit quantification of biophysical variables. With the aim of preparing for this new era of Earth observation, this review summarizes the state-of-the-art retrieval methods that have been applied in experimental imaging spectroscopy studies inferring all kinds of vegeta…

The master’s dissertation viva by video conference: strategies and best practices

2019

Durante la última década, se han publicado numerosos estudios sobre el proceso de elaboración y evaluación de los trabajos de fin de máster (TFM) (Da Cunha, 2016; García & Martínez-Clares, 2012; González-Calero & Turégano, 2011), sobre las fases de tutorización y acompañamiento al estudiante (Flores, Martínez, Martínez López, Pascual, & Sanz, 2013) y sobre las competencias a adquirir tras su finalización (Cabrera, Sangrà & Rodera, 2012; Serrano & Pontes, 2015; Viejo & Ortega Ruiz, 2018). Sin embargo, no resultan tan evidentes las investigaciones que analizan la fase de preparación y defensa pública de estos trabajos, siendo, sin embargo, la que genera más incomodidad entre el estudiantado. …

Oral microcirculation observed in vivo by videocapillaroscopy: a review

2009

Capillaroscopy is a non-invasive diagnostic technique that is fundamental in viewing peripheral circulation and in studying microangiopathies. The morphological study of microcirculat ion is of fundamental importance, mainly because the microvascular bed is directly involved in the etiopathogenesis of autoimmune disorders and acute and chronic inflammatory pathological conditions. The value of capillaroscopic investigation as a diagnostic means in cases of peripheral microcirculation disorders has been confirmed by numerous studies. Other studies used capillaroscopic investigations to evaluate microcirculation damage not as a complication of disease (diabetes), but as its initial stage, and…
