Durante los meses de agosto de 2019 a mayo de 2020 se desarrolló un Proyecto Piloto con el objetivo de certificar la producción de mieles con el estándar de Cadena de Custodia PEFC Chile en patrimonio de las empresas Forestal Mininco SA y Forestal Arauco SA certificadas bajo el estándar de Gestión Forestal Sostenible CERTFOR/PEFC con apicultores de las comunas de Mulchén, Huépil, Cañete y Los Álamos. Esto con el objetivo adicional de dar mayor valor agregado a una producción sostenible de mieles para su comercialización en el mercado local e internacional de los apicultores de la Región del Bio Bio.

This paper investigates the fee scheduling problem of electric vehicles (EVs) at the micro-grid scale. This problem contains a set of charging stations controlled by a central aggregator. One of the main stakeholders is the operator of the charging stations, who is motivated to minimize the cost incurred by the charging stations, while the other major stakeholders are vehicle owners who are mostly interested in user convenience, as they want their EVs to be fully charged as soon as possible. A biobjective optimization problem is formulated to jointly optimize two factors that correspond to these stakeholders. An online centralized scheduling algorithm is proposed and proven to provide a Pareto-optimal solution. Moreover, a novel low-complexity distributed algorithm is proposed to reduce both the transmission data rate and the computation complexity in the system. The algorithms are evaluated through simulation, and results reveal that the charging time in the proposed method is 30% less than that of the compared methods proposed in the literature. The data transmitted by the distributed algorithm is 33.25% lower than that of a centralized one. While the performance difference between the centralized and distributed algorithms is only 2%, the computation time shows a significant reduction.

Today, many users of multimedia applications are surrounded by a changing set of multimedia-capable devices. However, users can move their running multimedia applications only to a pre-defined set of devices. Application mobility is the paradigm where users can move their running applications (or parts of) to heterogeneous devices in a seamless manner. In order to continue multimedia processing under the implied context changes in application mobility, applications need to adapt the presentation of multimedia content and their internal configuration. We propose the system DAMPAT that implements an adaptation control loop to adapt multimedia pipelines. Exponential combinatorial growth of possible pipeline configurations is controlled by architectural constraints specified as high-level goals by application developers. Our evaluation shows that the pipeline only needs to be interrupted a few tens of milliseconds to perform the reconfiguration. Thus, production or consumption of multimedia content can continue across heterogeneous devices and user context changes in a seamless manner.

In the recent years, many efforts have been made for the development of the Grid workflow systems. Currently most Grid workflow systems focus on data analysis function or specific Grid applications, while building large-scale scientific collaborative applications is still not easy for common users. In this paper, requirement of Grid workflow spanning multiple grids was introduced firstly. Then, a highly scalable, more usable Grid workflow framework is proposed. The framework provides abstract components that facilitate Grid-based workflow construction, and can integrate multiple Grids' resources into a single system with an intuitive graphical user interface. Furthermore, a prototype system based on this framework was developed, along with a simple bioinformatics application workflow as a demonstration.
