Detecting Hotspots in Time and Space

چکیده
The numerical analysis of spatial point distributions has interested academics for many years. A very early work that resulted in the famous Moran’s I statistic was that by Moran (1948). An early important collection of work on general spatial analysis is that edited by Berry and Marble (1968). The development of spatial point analysis theory is illustrated by such later books by Cliff and Ord (1972, 1981), more recent papers by Ord and Getis (1995), Anselin (1995) and Gatrell et al (1996), the overview by Getis and Ord (1996), leading to large number of recent studies such as Cho (2003) using the techniques that have been developed over the last fifty years.

Evaluating the Success of Fine Dust Hotspots Control Projects Using Structural and Functional Characteristics of the Habitat in the West Shore of Urmia Lake
Introduction: As one of the most serious environmental challenges of Iran during the recent decade, the phenomenon of fine dust has occurred due to improper and excessive ecologic use of rangeland ecosystems, drought, and mismanagement of water resources. Knowing this phenomenon and being aware of the required strategies to fight against it play an essential role in reducing the number of dust ...
متن کاملIdentifying Carbon Sequestration Hotspots in Semiarid Rangelands (Case study: Baghbazm region of Bardsir city, Kerman province)
Carbon sequestration in rangeland ecosystems has been identified as a suitable strategy to offset greenhouse gas emissions that information of carbon sequestration hotspots is a good tool to improve rangeland management. Objectives for this study were to assessment potential carbon sequestration in various rangeland types, to identify carbon sequestration hotspots and to study the effective fact...
متن کاملUsing ecological niche modeling to determine avian richness hotspots
Understanding distributions of wildlife species is a key step towards identifying biodiversity hotspots and designing effective conservation strategies. In this paper, the spatial pattern of diversity of birds in Golestan Province, Iran was estimated. Ecological niche modeling was used to determine distributions of 144 bird species across the province using a maximum entropy algorithm. Richness...
متن کاملSequenceLDhot: detecting recombination hotspots
MOTIVATION There is much local variation in recombination rates across the human genome--with the majority of recombination occurring in recombination hotspots--short regions of around approximately 2 kb in length that have much higher recombination rates than neighbouring regions. Knowledge of this local variation is important, e.g. in the design and analysis of association studies for disease...
متن کاملIdentifying at Highway-Rail Grade Crossing Hotspots in Canada
This research presents a risk-based Hotspots identification model at highway-rail grade crossings in Canada. Two sets of models were developed to predict collision frequency and consequence at individual crossings. A two–dimensional graphic approach was adopted to combine these two models together to predict the risk at each crossing. Hotspots based on collision history tended to be widespread ...
متن کاملFeasibility of detecting and localizing radioactive source using image processing and computational geometry algorithms
We consider the problem of finding the localization of radioactive source by using data from a digital camera. In other words, the camera could help us to detect the direction of radioactive rays radiation. Therefore, the outcome could be used to command a robot to move toward the true direction to achieve the source. The process of camera data is performed by using image processing and computa...
