Optimal configuration for size-based burst assembly algorithms at the edge node for video traffic transmissions over OBS networks
2008
Optical burst switching (OBS) has been proposed to be a technology for implementing the next generation optical Internet. In this architecture, burst assembly algorithms have an important influence in the pattern traffic that characteristic this sort of optical networks. On the other hand, traffic coming from new applications (such as video on demand, Voice over IP, online gaming or Grid computing) that have real time and bandwidth constraints, has been experimented a rapid increment. Consequently, we consider important to evaluate the performance of traffic from real time applications over OBS networks. In this paper, we evaluate the effects of implementing a size-based burst assembly sche…
Effect and optimization of burst assembly algorithms for video traffic transmissions over OBS networks
2008
Optical burst switching (OBS) has been proposed to be a technology for implementing the next generation optical Internet. In this architecture, burst assembly algorithms have an important influence in the traffic pattern that characterizes this sort of optical networks. On the other hand, traffic coming from new applications (such as video on demand, Voice over IP, online gaming or Grid services) that have real time and bandwidth constraints has been experimented a rapid increment. Consequently, we consider important to evaluate the performance of the real time traffic over OBS networks. In this paper, we evaluate the video transmissions performance (MPEG4/RTP/UDP) over OBS networks, for bo…
Determinants of internet‐based corporate governance disclosure by Spanish listed companies
2008
PurposeThe purpose of this paper is to analyse the corporate governance information disclosed by Spanish listed companies on the internet, with the objective of assessing the extent and the influence of several corporate characteristics on the level of information voluntarily disclosed.Design/methodology/approachThe study took as its reference the existing literature on the examination of the quality of web sites and the importance of content as a key variable in determining web site quality. To quantify the corporate governance information disclosed by Spanish listed companies, three transparency indexes were designed. To contrast which variables determine the information provided online, …
Deslizamientos progresivos del placer: Sinergias del audiovisual pornográfico contemporáneo
2013
Los drásticos cambios estructurales experimentados en el sector audiovisual durante las últimas décadas tienen en la industria pornográfica el más cristalino ejemplo sobre cómo aspectos relativos a la dimensión económica de la producción afectan de manera drástica e inevitable a la evolución (o involución) de su gramática y construcción narrativa. El audiovisual pornográfico contemporáneo ha ampliado su presencia en la vida cotidiana de la población (al gozar de una mayor facilidad de acceso), aumentado hasta límites insospechados su principio rector de visibilidad óptima, espectacularizado los encuentros sexuales y radicalizado las prácticas extremas y violentas. The drastic structural cha…
One size hardly fits all
2013
This paper casts recent accomplishments in the field of Wireless MAC programmability into the emerging Software Defined Networking perspective. We argue that an abstract (but formal) description of the MAC protocol logic in terms of extensible finite state machines appears a convenient and viable data-plane programming compromise for modeling and deploying realistic MAC protocol logics. Our approach is shown to comply with existing control frameworks, and entails the ability to dynamically change the MAC protocol operation based on context and scenario conditions; in essence, move from the traditional idea of "one-size-fits-all" MAC protocol stack to the innovative paradigm of opportunistic…
Comparison of distance covered in paddle in the serve team according to performance level
2013
Although paddle is the second most practiced sport in Spain, the scientific knowledge about the players' work-load is still very low. The serve is a critical situation because the team has the opportunity to start the point attacking by approaching the net straight after the serve. However, the distance covered by the serve team still has not been studied in padel. OBJECTIVE: This study aimed to analyse the distance covered by the serve team according performance level. It was hypothesized that the server would cover more distance than his partner due to the approach to the net after the serve. Moreover, it also was hypothesized that the difference between serve and partner would be greater…
Design and Validation of the Brief Self Online Scale (SO-8) in Early Adolescence: An Exploratory Study
2020
For the Z-Generation, the Internet has become a very important experimentation laboratory for the discovery and validation of their identity. Despite the importance of the process of building the self in the adolescent, there are hardly any validated instruments that measure the self online. The aim of this research was to design and validate the Brief Self Online Scale (SO-8). A total of 843 students (384 boys, 45.6%), with an age range of 10 to 14 years participated. Confirmatory factor analysis (CFA) confirmed the hypothesized model of two correlated factors (Online Self-Perception and Online Idealized Projection), previously obtained through exploratory factor analysis (EFA). The relia…
Trends in Research and Publication: Science 2.0 and Open Access
2009
This paper considers current trends in academic research and publication, in particular as seen from the control community. The introduction of Web 2.0 applications for scientists and engineers is currently changing the way research is being conducted. In the near future, participants in the research community will be able to share ideas, data and results like never before. They will also be able to manage the rapidly increasing amount of scientific information much more effectively than today through collaborative efforts enabled by the new Internet tools. However, an important premise for such a development is the availability of research material. Many research results are currently shie…
Informing, engaging, mobilizing or interacting: Searching for a European model of web campaigning
2011
This study presents data from content analyses of the websites of all parties that stood in the 2009 European parliamentary elections in France, Germany, Great Britain and Poland. It cross-nationally examines the main functions of the websites, the adoption of Web 1.0 and Web 2.0 features, and the political and cultural factors that determine parties’ online communication. The findings show that while the main website function varies across countries, Web 1.0 is still the dominant mode of campaigning. Moreover, offline inequalities within and between nations determine differences in parties’ individual online strategies: specifically, major parties in states with long histories of democrac…
Big data ja analytiikka terveydenhuollossa
2016
Elämme datakeskeisessä maailmassa, jossa uutta digitaalista sisältöä syntyy jo muutamissa sekunneissa uskomattomia määriä. Yritykset ja organisaatiot pyrkivät analysoimaan tätä massiivista, monimuotoista ja nopeasti kasvavaa Big Dataa toimiakseen paremmin ja tehokkaammin sekä saadakseen parempaa ymmärrystä omasta toiminnastaan. Big Data ja analytiikka ovat aihe, jota on tutkittu laajasti myös terveydenhuollon näkökulmasta. Terveydenhuolto on yksi toimialoista, joka voi hyötyä Big Datasta ja siihen kohdistuvasta analytiikasta huomattavasti. Tässä tutkielmassa kysytään kuinka analytiikka on kehittynyt ja mihin suuntaan se on kehittymässä. Kysymykseen vastataan tutustumalla liiketoimintatiedon…
