Bumble bee semi-field studies: choice and management of colonies to reduce variability in assessment endpoints

The publication of the proposed EFSA risk assessment for pollinators resulted in an increasing demand for experiments with non-Apis pollinators (EFSA 2013).However, no official guideline for the standardized semifield trials exists so far.To overcome this lack of guidance, the development of semi-field study designs are under way.The methodology is

A Robust Conic Programming Approximation to Design an EMS in Monopolar DC Networks with a High Penetration of PV Plants

This research addresses the problem regarding the efficient operation of photovoltaic (PV) plants in monopolar direct current (DC) distribution networks from a perspective of convex optimization.PV plant operation is formulated as a nonlinear programming (NLP) problem while considering two single-objective functions: the minimization of the expecte
