We examine statistical isotropy of large scale anisotropies of the Internal Linear Combination (ILC) map, based on three year WMAP data. Our study reveals no significant deviation from statistical isotropy on large angular scales of 3-year ILC map. Comparing statistical isotropy of 3-year ILC map and 1-year ILC map, we find a significant improvement in 3-year ILC map which can be due to the gai...

Concept mapping has become a popular learning tool. However, the processes underlying the task are poorly understood. In the present study, we examined the effect of creating a concept map on the processing of item-specific information. In 2 experiments, subjects learned categorized or ad hoc word lists by making pleasantness ratings, sorting words into categories, or creating a concept map. Me...

Expertise in topographic map reading is dependent on efficient processing of geographical information presented in a standardised map format. Studies have supported the proposition that expert map readers employ cognitive schemas in which prototypical configurations held in long term memory are employed during the surface search of map features to facilitate map comprehension. Within the expert...

he Map/Reduce framework-a parallel processing paradigm-is widely being used for large scale distributed data processing. Map/Reduce can perform typical relational database operations like selection, aggregation, and projection etc. However, binary relational operators like join, cartesian product, and set operations are difficult to implement with Map/Reduce. Map/Reduce can process homogeneous ...

high processing loads, need for complicated and frequent updating, and high false alarm are some of the challenges in designing anomaly detection and misuse detection systems. we propose a new network-based intrusion detection system (ids) that resolves such shortcomings. our scheme fuses anomaly detection and misuse detection systems, which has not been utilized so far in existing systems. in ...

lineaments are the most important phenomena of geological exploration of hydrocarbon reservoirs . concepts in order to map the contours of land need so much time and money. one of the most famous methods in lineaments extraction is satellite image processing. in this paper, an overview of lineament extraction methods and a new method based on canny edge detection algorithm is raised. the result...

this paper presents a method for generating a digital management map to apply cyanazine pre-emergence herbicide. the main objective was to develop a precision method to generate management maps for the variable rate application of herbicide to reduce the amount of herbicide applied and its adverse impact on the environment. first, local and utm coordinates of a field were determined using total...

wildfire in forests and rangelands, apart from its initiating causes, is considered as an ecological disaster. zoning natural areas according to their susceptibility to fire helps to put off operations and reduces catastrophic losses caused through a wise management plan. in this study, the zoning map of wildfire risk in forest and rangeland areas has been produced using gis, analytical hierarc...
