Phylogeny and Biogeography of Ice Crawlers (Insecta: Grylloblattodea): Evidence from Six Molecular Loci
<p>Ice crawlers (Insecta: Grylloblattodea) are rarely encountered insects that consist of five genera representing 26 species from North America and Asia. Asian grylloblattids are the most diverse, but North American ice crawlers (genus Grylloblatta) are known for their adaptation to cold …

A novel defense mechanism against web crawler intrusion
<p>Web robots also known as crawlers or spiders are used by search engines, hackers and spammers to gather information about web pages. Timely detection and prevention of unwanted crawlers increases privacy and security of websites. In this research, a novel method to identify web crawlers is …

Understanding Japanese Maple Scale Biology to Inform Sustainable Pest Management Practices in Virginia Nurseries
… placing the tape method (for monitoring crawlers). A two-year study took place at two separate locations and on boxwoods (2022-2023) and red maples (2023). Our phenology findings indicated that there were two generations and prolonged crawler presence which can extend over a period of 34 …

Query Rewriting for Extracting Data behind HTML Forms
… As a result, enabling automated agents and Web crawlers to interact with form-based interfaces designed primarily for humans is of great value. This thesis describes a system that can fill out Web forms automatically according to a given user query against a global schema for an application …

Ontology learning for the semantic deep web
… cannot be indexed by the existing automated Web crawlers, with ontologies, resulting in the Semantic Deep Web. The Deep Web information is exploited in three different ways: extracting attributes from the Deep Web data sources automatically, generating domain ontologies from the Deep Web …

Query selection in Deep Web Crawling
… search engines. This calls for deep web crawlers to retrieve the data so that they can be used, indexed, and searched upon in an integrated environment. Unlike the surface web crawling where pages are collected by following the hyperlinks embedded inside the pages, there are no hyperlinks …

A Bandwidth-Conserving Architecture for Crawling Virtual Worlds
… to decrease the amount of data collected by crawlers, keep search engine collections up to date, and provide an efficient mechanism for collecting and searching information from multiple virtual worlds. Experimental results with data crawled from Second Life servers demonstrate that our …

Structural Model Discovery in Temporal Event Data Streams
… promise to bring new generations of powerful "crawlers" for knowledge discovery, e.g., face detection and crowd surveillance. Many aspects of data can be captured by such systems, e.g., temporal information, extractable visual information - color, contrast, shape, etc. However, these captured …

Phylogeny of the Polyneopterous Insects With Emphasis on Plecoptera: Molecular and Morpological Evidence
… more obscure web-spinners, angel insects and ice-crawlers. We present a phylogenetic analysis of the polyneopteran orders based on 18S rDNA, 28S rDNA, Histone 3, and a coded morphology matrix for an extensive sampling of taxa. We investigate the use of congruence between separate datasets as an a …

In Service Above Ground Storage Tank Inspection with a Remotely Operated Vehicle (ROV)
… some serious limitations to such systems as the crawlers used are in direct contact with the tank's structure, where obstacles inside the tanks present a problem. To make such remotely operated vehicular systems more flexible and reliable, this study investigates the fundamental requirements and …

Real time detection of malicious webpages using machine learning techniques
… of webpages that pose scalability issues and the crawlers' inability to visit intranet webpages that require computer operators to login as authenticated users. The thesis proposes to use various machine learning algorithms, both supervised and unsupervised to categorise webpages based on parsing …
