Recent advances in energy efficient data center (DC) design in combination with predictive optimization techniques have led to the emergence of DCs that are able to adapt their operation to their environment. Current approaches towards assessing the operational efficiency of the DCs are mostly static, disregarding the flexibility aspects of modern DCs, also(More)
A prospective study to verify the behavior of the arterial/alveolar oxygen tension ratio (PaO2/PAO2) at different fractions of inspired oxygen (FIO2), was performed in 15 adult hypoxemic patients. This index was useful not only for predicting the arterial oxygen tension but also for choosing the necessary oxygen supplementary levels. PaO2/PAO2 was a less(More)
Although several alternative definitions exist, a NetZero Energy Building (Net ZEB) can be succinctly described as a grid-connected building that generates as much energy as it uses over a year. The “net-zero” balance is attained by applying energy conservation and efficiency measures and by incorporating renewable energy systems. While based on annual(More)
This paper describes the CoolEmAll project and its approach for modeling and simulating energy-efficient and thermal-aware data centers. The aim of the project was to address energy-thermal efficiency of data centers by combining the optimization of IT, cooling and workload management. This paper provides a complete data center model considering the(More)
CoolEmAll project aims at improving energy-efficiency of data centers. The main results of CoolEmAll include data center Simulation, Visualization and Decision tools (SVD Toolkit) and models of Data Center Efficiency Building Blocks (DEBBs). The resulting tools of CoolEmAll will permit planners and operators of data centers to carry out flexible and fast(More)
Significant data centers energy footprints and the increase in energy prices have stimulated investigations into possible metrics and methods to define, quantify and improve the energy efficiency of data centers and federated cloud environments. Studies include metrics and analyses from various points of views, that address both design and operation phases.(More)
The calculus of building energy consumption is a demanding task because multiple factors must be considered during experimentation. Additionally, the definition of themodel and the experiments is complex because the problem ismultidisciplinary. When we face complex models and experiments that require a considerable amount of computational resources, the(More)
In this paper we address the problem of define and execute an environmental model, that describes the behavior of a building from the point of view of sustainability, in a distributed scenario. The inherent complexity of the experiment and the demanding amount of resources needed to perform the calculus, justify the need of distribute the execution of the(More)
