This paper presents StealthGuard, an efficient and provably secure proof of retrievabillity (POR) scheme. StealthGuard makes use of a privacypreserving word search (WS) algorithm to search, as part of a POR query, for randomly-valued blocks called watchdogs that are inserted in the file before outsourcing. Thanks to the privacy-preserving features of the WS, neither the cloud provider nor a thi...

A numerical simulation has been carried out to study the detonability characteristics of two- phase unconfined clouds. The parameters equivalence ratio, turbulence, shape, volume and uniformity of the cloud and the delay time distribution are recognized and introduced as the most important factors determining the reactivity of the cloud and influencing the initiation of a successful detonation....

The last two decades were marked by an exponential growth in the volume of data originating from various data sources, from mobile phones to social media contents, all through the multitude devices of the Internet of Things. This flow of data can’t be managed using a classical approach and has led to the emergence of a new buzz word: Big Data. Among the research challenges related to Big Data t...

The present study aims at introducing a new efficient approach to store data in a cloud server. The approach is applicable to a group of annotated text files, which are supported by Microsoft Word (docx, doc, pdf, etc.). Instead of the original document, an intermediate file is produced and saved as a Microsoft Excel document for each user. The file contains edited information including highlig...

Ontology search interfaces can benefit from the latest information retrieval advances. This paper introduces a Conjunctive Ontology Browser and Explorer (COBE) for searching and exploring SNOMED CT concepts and visualizing SNOMED CT fragments. COBE combines navigational exploration (NE) with direct lookup (DL) as two complementary modes for finding specific SNOMED CT concepts. The NE mode allow...

Search engine result pages (SERPs) are known as the most expensive real estate on the planet. Most queries yield millions of organic search results, yet searchers seldom look beyond the first handful of results. To make things worse, different searchers with different query intents may issue the exact same query. An alternative to showing individual web pages summarized by snippets is to repres...

Collaborative editing is a highly helpful feature that one can receive from word processor. Due to this reason, Google Docs and other applications such as Google cloud connect and CodoxWord have come into existence. These are much similar in the case of functions but there are several differences between them. Based upon the interface and other functionalities that allow the software to perform...

abstract the limitation of water sources in most places all over the world, especially in arid and semi-arid lands is an important issue for those who live in these areas. many governments have dedicated their efforts toward finding new water resources to obtain water. fog and cap clouds harvesting are one of the candidate methods to produce pure water. many countries including chile, peru, ecu...

conclusions the findings of this study indicate that the frequency of disfluencies was increased in difficult syllable structures in comparison to simple syllable structures. according to the results, it seems that certain linguistic features, such as syllable structure can affect speech-motor output in people who stutter through affecting phonological encoding. background stuttering is one of ...
