Paper presented at the 2017 IEEE International Symposium on Circuits and Systems (ISCAS), held in Baltimore, MD, USA, on 28-31 May 2017.
A prospect for computing in porous materials research: Very large fluid flow simulations
2016
Abstract Properties of porous materials, abundant both in nature and industry, have broad influences on societies via, e.g. oil recovery, erosion, and propagation of pollutants. The internal structure of many porous materials involves multiple scales which hinders research on the relation between structure and transport properties: typically laboratory experiments cannot distinguish contributions from individual scales while computer simulations cannot capture multiple scales due to limited capabilities. Thus the question arises how large domain sizes can in fact be simulated with modern computers. This question is here addressed using a realistic test case; it is demonstrated that current …
Comparing RADseq and microsatellites for estimating genetic diversity and relatedness : Implications for brown trout conservation
2019
The conservation and management of endangered species requires information on their genetic diversity, relatedness and population structure. The main genetic markers applied for these questions are microsatellites and single nucleotide polymorphisms (SNPs), the latter of which remain the more resource demanding approach in most cases. Here, we compare the performance of two approaches, SNPs obtained by restriction-site-associated DNA sequencing (RADseq) and 16 DNA microsatellite loci, for estimating genetic diversity, relatedness and genetic differentiation of three, small, geographically close wild brown trout (Salmo trutta) populations and a regionally used hatchery strain. The genetic di…
<title>Managing compressed multimedia data in a memory hierarchy: fundamental issues and basic solutions</title>
1998
The purpose of the work is to discuss the fundamental issues and solutions in managing compressed and uncompressed multimedia data, especially voluminous continuous mediatypes (video, audio) and text in a memory hierarchy with four levels (main memory, magnetic disk, (optical or magnetic) on-line/near-line low-speed memory, and slow off-line memory, i.e. archive). We view the multimedia data in such a database to be generated, (compressed), and stored into the memory hierarchy (at the lowest non-archiving level), and subsequently retrieved, (decompressed), and presented. If unused, the data either travels down in the memory hierarchy or it is compressed and stored at the same level. We firs…
La vocalidad del violín en el norte de Italia en torno a 1600
2021
Throughout the present research I intend to demonstrate the powerful link between the vocal practice in accompanied monody and the way Early Italian violin music ought to be interpreted. Due to the scarce amount of articulation and ornamentation in this music, I consider that historical criteria should be found in order to back up the subjective choices in its performance. According to this, I focus on reviewing sources that describe the vocal practice around 1600, but also contemporary sources in which we can find instructions addressed to bow instruments. Besides, a catalogue of articulations and ornamentations present in early editions of printed violin music is attached. Last, I comment…
Gatherer: an environmental monitoring application based on IPv6 using wireless sensor networks
2013
In this paper, we present an environmental monitoring application based on IPv6 using wireless sensor networks. We show the guidelines to connect this network to internet using the 6LowPAN standard with a real prototype in the evolution of the Internet of Things. We assign a unique IPv6 address to the different nodes motes of the network. Gatherer is based on TinyOS using IPv6 and UDP protocols and allows the data gathering of temperature and relative humidity from the different motes, requesting specific data from individual motes when required, increasing the accuracy of the measures. We compare the performance of our IPv6-based proposed application against others and show the benefits of…
ADVERSE EFFECTS OF GONADOTROPINS USED IN INFERTILITY TREATMENT
2019
Introduction: Infertility represents a problem for more and more couples all over the world, including in Romania. Thus, more and more women need to resort to drugs to treat infertility, treatments which are not without adverse reactions (Boivin et al., 2007). Modern therapy brings significant benefits in the treatment of infertility. Despite all the benefits, the controlled ovarian stimulation treatment does not lack the possibility of adverse reactions to the administered drugs.
 Objectives: The aim of this study was to determine the potential adverse reactions experienced by patients during the treatment with gonadotropins followed by assisted conception
 Methods: A study was d…
Formal verification of a Cooperative Automatic Repeat reQuest MAC protocol
2012
Author's version of an article published in the journal: Computer Standards & Interfaces. Also available from the publisher at: http://dx.doi.org/10.1016/j.csi.2011.12.001 Cooperative communications, in which a relay node helps the source node to deliver its packets to the destination node, are able to obtain significant benefits in terms of transmission reliability, coverage extension and energy efficiency. A Cooperative Automatic Repeat reQuest (C-ARQ) MAC protocol has been recently proposed to exploit cooperative diversity at the MAC layer. in this paper, we validate the integrity and the validity of the C-ARQ protocol using formal methods. The protocol logic is modeled in SDL and implem…
Las formas de tratamiento en el corpus PRESEEA-Valencia. Un estudio sociolingüístico
2018
En este artículo se hace un estudio de las formas de tratamiento utilizadas, tanto por el entrevistador como por los informantes, en el corpus PRESEEA-Valencia. Dicho estudio incluye un análisis cuantitativo, en el que se da cuenta de los resultados atendiendo al nivel sociocultural, el sexo, la edad y la lengua habitual de los informantes, y un estudio cualitativo, centrado en las motivaciones que llevan al interlocutor a utilizar una u otra forma de tratamiento. This work is a study of the form of address used both by the interviewer and the informants in the corpus belonging to PRESEEA - Valencia. This study includes a quantitative analysis, which shows the results according to the socio…
L'evolució de la referència als participants en el debat parlamentari en català (1932-2013)
2018
Aquest article presenta sumàriament els primers resultats d'una recerca en curs que té com a objectiu estudiar l'evolució de les estratègies lingüístiques i discursives utilitzades per a la referència als participants en el Parlament de Catalunya en el perí-ode 1932-38 (durant la Segona República Espanyola) i en el període que va des de la recuperació de les institucions democràtiques catalanes, el 1980, fins al 2013. L'anàlisi combina els mètodes qualitatius amb els quantitatius i mostra diverses tendències en l'evolució de l'ús de les diferents formes i estratègies. La incorporació dels marcs par-ticipatius de Goffman (1981) a l'anàlisi proporciona un conjunt de dades que, un cop descrite…
