A major goal of imaging, graphics, and visualization systems is to help doctors, scientists, engineers, and analysts identify patterns and features in complex data. Some feature-extraction system use algorithms to automatically identify features. Other methods use human observers to identify features visually, or to discover features by interactively manipulating visual representations. Althoug...

We present a method for learning wrappers for multi-slot extraction from semi-structured documents. The presented method learns how to construct automatically wrappers from positive examples, consisting of text tuples occurring in the document. These wrappers (T-wrappers) are based on a feature structure unification based pattern language for information extraction. The presented technique is a...

This chapter evaluates the performance of edge-based directional probability distributions as features in writer identification in comparison to a number of other texture-level features encoding non-angular information. We introduce here a new feature: the joint probability distribution of the angle combination of two ”hinged” edge fragments. It is noted that the ”edge-hinge” distribution outpe...

Automated question generation approaches have been proposed to support reading comprehension. However, these approaches are not suitable for supporting writing activities. We present a novel approach to generate different forms of trigger questions (directive and facilitative) aimed at supporting deep learning. Useful semantic information from Wikipedia articles is extracted and linked to the k...

Small passerine birds in the north need to take advantage of several behavioral and physiological mechanisms maintain energy balance during winter characterized by low food supply, ambient temperatures, short days. Here we test if breathing pattern a non-migratory species, great tit ( Parus major ), show seasonal variation that could help species keeping positive winter. To this aim, measured o...

Shrimp farming is a small but growing industry in New Caledonia. Since 1993, "Syndrome 93" has been affecting New Caledonian shrimp farming industry every cold season, causing severe epizootic mortalities in grow-out ponds and significant losses. Highly pathogenic strains of Vibrio penaeicida are considered the etiological agent of the disease in Litopenaeus stylirostris. On one hand, studies d...

Conventional pattern recognition systems have two components: feature analysis and pattern classification. Feature analysis is achieved in two steps: parameter extraction and feature extraction. Feature extraction and pattern classification can be conducted independently or jointly. Two popular independent feature extraction algorithms are Linear Discriminant Analysis (LDA) and Principal Compon...

There is a close connection between saltwater intrusion into aquifers and groundwater extraction. Freshwater extraction in coastal aquifers is one of the most important reasons for the saltwater intrusion into these aquifers. Condition of extraction system such as well depth, discharge rate, saltwater concentration and etc. could affect this process widely. Thus, investigating different extract...

water contamination due to the wide variety of pesticides used in agriculture is a global environmental pollution problem. in order to reach at sub-î¼gl-1 levels of detection, an efficient extraction technique is required. a simple, fast and economical method, dispersive liquid-liquid micro extraction (dllme), followed by gas chromatography-mass spectrometry was assessed for determining endosul...
