In this paper, a novel method is proposed and applied to quickly calculate the capacity of energy storage for stand-alone and grid-connected wind energy systems, according to the discrete Fourier transform theory. Based on practical wind resource data and power data, which are derived from the American Wind Energy Technology Center and HOMER software separately, the energy storage capacity of a...

Maintaining data availability is one of the biggest challenges in decentralized online social networks (DOSNs). The existing work often assumes that the friends of a user can always contribute to the sufficient storage capacity to store all data. However, this assumption is not always true in today's online social networks (OSNs) due to the fact that nowadays the users often use the smart mobil...

There is a wealth of research on storage systems, focusing on the storage system architecture, intelligent use of storage resources, and mass storage systems. However, very little research looks at a key component of centralized storage systems, the physical fabric of the network that holds the storage system together. “Best practice” frameworks for the management of storage systems exist, but ...

Ever-Increasing Demands for More Storage Capacity Demand for DVDs continues to grow; DVD system sales are estimated to increase from 95 million units sold in 1998 to over 175 million units in 2001. This popularity is not surprising given that a DVD can hold enough data (up to 8.5 gigabytes on a dual layer disc) to play back an entire motion picture on a standard television with far greater clar...

Humans show a severe capacity limit in the number of objects they can store in visual short-term memory (VSTM). We recently demonstrated with functional magnetic resonance imaging that VSTM storage capacity estimated in averaged group data correlated strongly with posterior parietal/superior occipital cortex activity (Todd & Marois, 2004). However, individuals varied widely in their VSTM capaci...

The aim of this work was to determine antioxidant capacity of beverages containing black, white, and green tea extracts using the photochemiluminescence method, and to monitor its changes based on the storage temperature and time. Samples were stored at two different temperatures (refrigerated at 4°C and laboratory temperature 22°C), analyzed after opening of the original package, and consequen...
