TL;DR: A survey of migration mechanisms developed to provide high availability inside virtualized environments is reported and these approaches are classified in three main classes: process migration, memory migration, and suspend/resume migration.
Abstract: In the virtualization area, replication has been considered as a mechanism to provide high availability. A high-availability system should be active most of the time, and this is the reason that its design should consider almost zero downtime and a minimal human intervention if a recovery process is demanded. Several migration and replication mechanisms have been developed to provide high availability inside virtualized environments. In this article, a survey of migration mechanisms is reported. These approaches are classified in three main classes: process migration, memory migration, and suspend/resume migration.

TL;DR: In this paper, a critical review of RO theory, its state of the art, and its applications to electricity generation projects (EGP) and renewable energy projects (REP) is presented.
Abstract: Real options (RO) theory is well known for enhancing the value of projects under uncertainty. This is achieved by modelling the flexibility that managers possess to adjust the projects in response to changes in their environments. Based on this, RO theory could be used to tackle current energy and environmental issues by enhancing the value of electricity generation projects (EGP), especially renewable energy projects (REP). The potential of RO theory to increase the value of EGP and REP has been a driver for new research in the topic. However, existing literature is still scarce, diverse, and tends to neglect the state of the art of RO theory (e.g. RO in the design of projects). RO studies tend to ignore the use of RO in the design of projects as they are difficult to formulate without the help of experts on the projects' designs. This paper aims to encourage novel research in the application of RO theory to EGP and REP. For this purpose, a critical review of RO theory, its state of the art, and its applications to EGP and REP is presented. This review identifies current areas of interest and gaps in knowledge in this research area. It is concluded that new and novel RO research should address the state of the art of RO theory, and uncertainties that are exclusive for specific types of projects. This future research will require the involvement of electrical engineers specialised in the design of EGP and REP.

TL;DR: In this article, the green synthesis of Fe3O4 nanoparticles by cynara cardunculus leaf extract is presented, which offers a novel and eco-friendly alternative to obtaining of iron oxides nanoparticles.
Abstract: In this work the green synthesis of Fe3O4 nanoparticles by cynara cardunculus leaf extract is presented. This green synthesis route offers a novel and eco-friendly alternative to obtaining of iron oxides nanoparticles. Functional nanoparticles with potential catalytic applications, particularly for water remediation containing organic dyes were synthetized. The structural characterization of the Fe3O4 nanoparticles were carried out by scanning electron microscopy (SEM), X-ray diffraction, techniques. Calculation to obtaining the crystallite size by Williamson –Hall method were performed. Additionally, Raman spectroscopy support the Fe3O4 characterization. Posteriorly, the Fe3O4 nanoparticles were evaluated on the methylene blue degradation. Kinetic adsorption models were employed to establish the behavior during the methylene blue degradation process. Pseudo first order, Pseudo second order, Intraparticle diffusion and Elovich Models were calculated based on the experimental data obtained. Calculations as the correlation factor indicates the best linear fit between the theoretical models and the experimental data obtained during the blue methylene degradation.

TL;DR: In this article, a single-stage high-power-factor high-efficiency electronic ballast for compact fluorescent lamps is presented, which uses two voltage sources connected in series to feed the inverter ballasting the lamp, one of them consists in the rectified line voltage and the other in a dc-dc converter operating in discontinuous conduction mode.
Abstract: In this paper, a single-stage high-power-factor high-efficiency electronic ballast for compact fluorescent lamps is presented. The proposed topology uses two voltage sources connected in series to feed the inverter ballasting the lamp, one of them consists in the rectified line voltage and the other in a dc-dc converter operating in discontinuous conduction mode. In this way, the converter processes a lower energy than the nominal power of the lamp. The proposed topology presents simplicity, high-power-factor, low current crest factor, and high efficiency.
