We present an approach for particle mass generation in which the physical vacuum is assumed as a medium at zero temperature and where the dynamics of the vacuum is described by the Standard Model without the Higgs sector. In this approach fermions acquire masses from interactions with vacuum and gauge bosons from charge fluctuations of vacuum. The obtained(More)
Sampling from conditional distributions is a problem often encountered in statistics when inferences are based on conditional distributions which are not of closed-form. Several Markov chain Monte Carlo (MCMC) algorithms to simulate from them are proposed. Potential problems are pointed out and some suitable modifications are suggested. Approximations based(More)
a r t i c l e i n f o a b s t r a c t We describe a new version of GBS, a 3D global, flux-driven plasma turbulence code to simulate the turbulent dynamics in the tokamak scrape-off layer (SOL), superseding the code presented by Ricci et al. (2012) [14]. The present work is driven by the objective of studying SOL turbulent dynamics in medium size tokamaks(More)
It is clear that the development of new methodologies that increase the electrical systems efficiency and the welfare of users, avoiding pollution as best as possible, are highly desired by researchers and utilities. In this context, in Ecuador, basic service elements like water heaters are usually used by population. Where, currently water heaters based on(More)
A limitation of existing P2P VoD services is their inability to support efficient streamed access to niche content that has relatively small demand. This limitation stems from the poor performance of P2P when the number of peers sharing the content is small. In this paper, we propose a new provider-managed P2P VoD framework for efficient delivery of niche(More)
Based on the change of the productive and energetic matrix of Ecuador, that consist in the substitution of liquid gas coming from black oil for electricity to cook food and water heating for human use in residential areas, a prototype Toroidal Coil (TC) for a water heater Magnetic Induction (MI) is presented in this article.
In the investigation of new methodologies and technologies, with the purpose of developing a major efficiency in the Electrical Systems of Power, whilst also finding methods to mitigate or minimize the disadvantages or risks to the environment; they have found ways to innovate new unconventional techniques of securing the electrical energy to implement to(More)
This paper describes the image registration block developed in the hepatic planner HepaPlan. The proposed method is intended to support clinical decisions about treatment of liver pathologies. The initial stage is the segmentation of the liver tissue as well as its internal structures and tumours in contrast-enhanced CT volumes. The second stage is(More)
