Mobile networks differ from their wireline counterparts mainly by the high costs for air transmissions and by the mobility of the users. A new entity, denoted as the crawling peer, is suggested in order to optimize the resource mediation mechanism for a mobile P2P file sharing application. In [1], we have investigated the performance of a crawling peer by means of simulations. Now, we show a ti...

abstract background: transpupillary thermotherapy is a new treatment for subfoveal choroidal neovascularization which needs further evaluation. this study was aimed to evaluate the efficacy of transpupillary thermotherapy on regression of occult subfoveal choroidal neovascularization with or without pigment epithelial detachment in patients with age-related macular degeneration. methods: in a c...

Search engines are the tools for Web site navigation and search. Search engines maintain indices for web documents and provide search facilities by continuously downloading Web pages for processing. This process of downloading web pages is known as web crawling. In this paper we propose A neural network based change detection method in migrating parallel web crawler. This method for Effective M...

The rapid growth of the Internet has put us into trouble when we need to find information in such a large network of databases. At present, using topic-specific web crawler becomes a way to seek the needed information. The main characteristic of a topic-specific web crawler is to select and retrieve only relevant web pages in each crawling process. There are many previous researches focusing on...

Distributed crawling has shown that it can overcome important limitations of the centralized crawling paradigm. However, the distributed nature of current distributed crawlers is currently not fully utilized. The optimal benefits of this approach are usually limited to the sites hosting the crawler. In this work we describe IPMicra, a distributed location aware web crawler that utilizes an IP a...

To investigate the intraand inter-limb muscle coordination mechanism of human hands-and-knees crawling by means of muscle synergy analysis, surface electromyographic (sEMG) signals of 20 human adults were collected bilaterally from 32 limb related muscles during crawling with hands and knees at different speeds. The nonnegative matrix factorization (NMF) algorithm was exerted on each limb to ex...

We present a novel profile-based focused crawling system for dealing with the increasingly popular social media-sharing websites. In this system, we treat the user profiles as ranking criteria for guiding the crawling process. Furthermore, we divide a user’s profile into two parts, an internal part, which comes from the user’s own contribution, and an external part, which comes from the user’s ...

The pervasiveness of the Internet makes it an ideal medium for sharing scholarly information. Nowadays, many authors post their publications online so that others may easily access to them, increasing the author’s impact in his/her research area. In this project, we develop a focused crawling to find publication pages, web pages that link to online, freely available scholarly publications. In c...

We demonstrate here a new approach to Web archival crawling, based on an applicationaware helper that drives crawls of Web applications according to their types (especially, according to their content management systems). By adapting the crawling strategy to the Web application type, one is able to crawl a given Web application (say, a given forum or blog) with fewer requests than traditional c...
