Thermal-aware relocation of servers in green data centers

Muhammad Tayyab CHAUDHRY,T. C. LING,S. A. HUSSAIN,Xin-zhu LU

Frontiers of Information Technology & Electronic Engineering 2015, Volume 16, Issue 2, Pages 119-134 doi: 10.1631/FITEE.1400174

Abstract: As an added effect of rise in inlet air temperature, some active servers may start exhaling intenselyIdentifying and comparing the thermal sensitivity to inlet air temperature for various servers helpsThe peak outlet temperature among the relocated servers can be lowered and even be homogenized to reducea proactive approach for thermal-aware relocation of data center servers.Thus, the thermal-aware relocation of servers helps in the establishment of green data centers.

Model server enabled management of collaborative changes in building information models

Muhammad Tariq SHAFIQ, Jane MATTHEWS, Steve LOCKLEY, Peter E.D. LOVE

Frontiers of Engineering Management 2018, Volume 5, Issue 3, Pages 298-306 doi: 10.15302/J-FEM-2018009

Abstract:

The issues and challenges involved in controlling the collaborative changes in a Building Information Modeling (BIM) data repository, in a multi-model collaboration environment, are discussed. It is suggested that managing iterative changes in BIMs is a database problem, exacerbated by the long transaction times needed to support collaborative design progression. This is yet to be resolved in the construction industry and better solutions are needed to support the underlying workflows and computing operations for seamless collaboration on BIMs. With this in mind, this paper proposes the use of the structural and semantic characteristics of BIM objects as a mechanism for tracking changes across co-developed solutions. The creation of object signatures, using hash codes derived from their characteristics, provides a potential mechanism for object comparison and effective change recognition and management.
