Cloud storage service is one of cloud services where cloud service provider can provide storage space to customers. Because cloud storage service has many advantages which include convenience, high computation and capacity, it attracts the user to outsource data in the cloud. However, the user outsources data directly in cloud storage service that is unsafe when outsourcing data is sensitive fo...

Provenance-aware storage systems (PASS) are a new class of storage system treating provenance as a first-class object, providing automatic collection, storage, and management of provenance as well as query capabilities. We developed the first PASS prototype between 2005 and 2006, targeting scientific end users. Prior to undertaking the provenance challenge, we had focused on provenance collecti...

Caching static HTTP traffic in proxy-caches has reduced bandwidth consumption and download latency. However, web-caching performance is hard to increase further due to the growing number of noncachable dynamic web-documents. Delta-encoding is a promising technique that exploits temporal correlation among different snapshots of a dynamic document, and renders dynamic traffic cachable. It achieve...

Cloud computing is an emerging computing paradigm that enables users to remotely store their data on a cloud so as to enjoy scalable services on-demand. It has been found that maintaining the privacy of data from an unauthorized user is really a major challenge. This is a major concern as such data is outsourced to keep storage at third parties say cloud service providers. It is very much essen...

Storage conditions of oil seeds before industrial extraction might influence the quality of the crude oil. The aim of present study was to clarify the storage able potency of high and low oleic cultivars of sunflower based on oil and fatty acid changes of seeds and their viability. The seed samples of four sunflower cultivars (two high oleic and two low oleic) were stored in three different tem...

In this paper a new approach for design of class-AB current-mode square-root domain filters based on the electronically simulated translinear loop principle is presented. FG-MOS transistors that operate in strong inverted saturation region are employed for implementation of translinear loop circuit. The filter achieves immunity to body effect, low circuit complexity, large input dynamic ran...
