Delivering Energy Proportionality with Non Energy-Proportional Systems - Optimizing the Ensemble

With power having become a critical issue in the operation of data centers today, there has been an increased push towards the vision of “energy-proportional computing”, in which no power is used by idle systems, very low power is used by lightly loaded systems, and proportionately higher power at higher loads. Unfortunately, given the state of the art of today’s hardware, designing individual ...

Platelet Refractoriness and how it is formed

Abstract Background and Objectives Transfusion of platelet has become one of the main treatments for thrombocytopenic patients to reduce the severity and frequency of bleeding consequences. Failure to attain the desired level of platelets in a patient following platelet transfusion is defined as platelet refractoriness. The purpose of present paper is to review and study the mechanisms involve...

Energy Efficiency Is Not Enough, Energy Proportionality Is Needed!

Due to the energy consumption/resource utilization characteristics of todays centralized DB servers, the fastest configuration is also the most energy-efficient one. Extensive use of SSDs alone cannot enable a fundamental change of this overall picture, because the storagerelated energy consumption is typically only a little fraction of the overall energy budget. Even, when this storage-related...

Patient Safety Behavior in Physicians: How is it Predicted?

Background: Patient safety is a serious global public health issue. Estimates show that every day many patients are harmed while receiving hospital care. Health care staff plays a key role in providing quality and safe patient care, especially physicians who are main members of the medical team and a critical element in patient safety efforts. Objective: ...
