A review of performance and energy aware improvement methods for future green cloud computing

With the advent of increased use of computers and computing power, state of the art of cloud computing has become imperative in the present-day global scenario. It has managed to remove the constraints in many organizations in terms of physical internetworking devices and human resources, leaving room for better growth of many organizations. With all these benefits, cloud computing is still facing a number of impediments in terms of energy consumption within data centers and performance degradation to end users. This has led many industries and researchers to find feasible solutions to the current problems. In the context of realizing the problems faced by cloud data centers and end users, this paper presents a summary of the work done, experimentation setup and the need for a greener cloud computing technique/algorithm which satisfies minimum energy consumption, minimum carbon emission and maximum quality of service

Learning analytics collaborative cluster activity in years 2 & 3

The Scottish Higher Education Enhancement Committee (SHEEC) agreed at its 18th September 2017 meeting that the new Enhancement Theme would be Evidence for Enhancement: Improving the Student Experience. It was proposed that groups of institutions would work collectively together as Collaborative Clusters on an area related to the Theme that would be beneficial to their own institution but has the potential to add value for the whole sector.QAA Scotland provided support for the facilitation of scoping activity workshops that brought institutions together with a shared interest in the key area of learning analytics. The purpose of these workshops was to create the space for institutions that are committed to specific areas related to the Theme to come together, and discuss in detail what areas of work they are keen to pursue in collaboration with other institutions.This presentation will report the collaborative cluster formed through these workshops, the work of these clusters, and outline the anticipated outcomes and impact as a result of this work.Key messages:1. Knowledge of the learning analytics collaborative cluster work to be undertaken in Years 2 & 3 of the Theme.2. An overview of strands of learning analytics work, their activities and anticipated outcomes.3. An understanding of how a scoping workshop approach can be used as a method to facilitate collaborative working
