Cloud computing has emerged as the leading paradigm for information technology businesses. Cloud computing provides a platform to manage and deliver computing services around the world over the Internet. Cloud services have helped businesses utilize computing services on demand with no upfront investments. The cloud computing paradigm has sustained its growth, which has led to increase in size and...
This paper presents design and modeling of a highly efficient node-level DC uninterruptible power supply (UPS) in rack-level DC power architecture. In the previous research, we proposed the architecture of the highly efficient rack-level DC system combined with node-level DC UPS. This paper deals with the design and modeling of proposed node-level DC UPS.
A low power reconfigurable DCT architecture is proposed, which can be run at three transform precision levels for different demands. Using the character of energy distribution of the DCT matrix after 2D DCT operation, we selected the best DCT bases which achieve considerable power reduction in DCT operation with minimum image quality degradation. The reconfigurable architecture can achieve power saving...
