Social network measures for "nosduocentered" networks, their predictive power on performance

Our purpose in this article is to define a network structure which is based on two egos instead of the egocentered (one ego) or the complete network (n egos). We describe the characteristics and properties for this kind of network which we call “nosduocentered network”, comparing it with complete and egocentered networks. The key point for this kind of network is that relations exist between the two main egos and all alters, but relations among others are not observed. After that, we use new social network measures adapted to the nosduocentered network, some of which are based on measures for complete networks such as degree, betweenness, closeness centrality or density, while some others are tailormade for nosduocentered networks. We specify three regression models to predict research performance of PhD students based on these social network measures for different networks such as advice, collaboration, emotional support and trust. Data used are from Slovenian PhD students and their s

Disseny i implementació d’una “Storage Area Network”

El següent projecte consisteix en analitzar com funciona un sistema SAN, per tal de veure com es pot obtenir un millor rendiment. L’objectiu principal es saber com es comportarà la nostra SAN muntada amb iSCSI a través de la xarxa, volem veure quines són les operacions, les dades i els resultats que comporta crear una RAID a través de discos no locals d’un ordinador i a través d’una xarxa LAN

La Participació d'estudiants i professors en una network d'infermeria

El 17th Annual Meeting of the Florence Network (FN) va tenir lloc del 21 al 25 d’abril de 2009 a The Hague University of Applied Sciences (THU) Academy of Health-School of Nursing, sota el lema: “Patient/client centred healthcare”. The Ducht perspective with an international touch”, i es va centrar en l’actual situació dels drets dels pacients a Holanda aplicat en diferents camps de les cures infermeres. L’Escola d’Infermeria de la Universitat de Girona hi va participar amb l’assistència de dues professores i quatre estudiants. E nombre total d’estudiants que varen assistir a la FN es de 47. La procedència dels mateixos en total de 9 països diferents. De tots ells assistien per primer cop 18 persones 4 ho feien per segona vegada i 1 per tercera . Els objectius del treball que es presenta son els següents: 1, Conèixer l’opinió dels estudiants respecte a la seva participació a la Florence Network. 2, Saber quin perfil tenen els universitaris que hi assisteixen 3, Detectar els punts forts i els punts febles que destaquen els estudiants després de participar a la Florence Network

Enhancing MPLS QoS routing algorithms by using the network protection degree paradigm

IP based networks still do not have the required degree of reliability required by new multimedia services, achieving such reliability will be crucial in the success or failure of the new Internet generation. Most of existing schemes for QoS routing do not take into consideration parameters concerning the quality of the protection, such as packet loss or restoration time. In this paper, we define a new paradigm to develop new protection strategies for building reliable MPLS networks, based on what we have called the network protection degree (NPD). This NPD consists of an a priori evaluation, the failure sensibility degree (FSD), which provides the failure probability and an a posteriori evaluation, the failure impact degree (FID), to determine the impact on the network in case of failure. Having mathematical formulated these components, we point out the most relevant components. Experimental results demonstrate the benefits of the utilization of the NPD, when used to enhance some current QoS routing algorithms to offer a certain degree of protection
