Developing an evolution model of the Internet has been a long standing research challenge. Such a model can improve the design and placement of communication infrastructure, reducing costs and improving users’ quality of experience. While communication infrastructure is tightly coupled to geographical locations, Internet modelling and forecasting in the last decade used network elements that ar...

Summary The genome-wide chromosome conformation capture (Hi-C) has revealed that the eukaryotic genome can be partitioned into A and B compartments that have distinctive chromatin and transcription features. Current Principle Component Analyses (PCA)-based method for the A/B compartment prediction based on Hi-C data requires substantial CPU time and memory. We report the development of a method...

I examine whether multiple health-related quality of life (HRQoL) measures are stratified by socioeconomic status (SES) and geographic location in the United States, and whether these disparities come from the demand side of the patient or the supply side of physicians. Data are from the 2005/2006 National Health Measurement Study (NHMS), a telephone survey of a nationally representative sample...

The geographic element through studies of cities and regions has recently been rediscovered in economic research. Understanding why economic activity tends to concentrate geographically is by many believed to hold important information for the understanding of economic growth and international trade in general. Early contributions of the classical location theory provide the first explanations ...

Spatial co-location patterns are the subsets of Boolean spatial features whose instances are often located in close geographic proximity. Co-location rules can be identified by spatial statistics or data mining approaches. In data mining method, Association rule-based approaches can be used which are further divided into transaction-based approaches and distance-based approaches. Transaction-ba...

The lack of adoption of a DNS-based geographic location service as proposed in RFC 1876 has lead to the deployment of alternative ways to locate Internet hosts. The two main alternatives rely either on active probing of individual hosts or on doing exhaustive tabulation of IP address ranges and their corresponding locations. Using active measurements, we show that the geographic span of blocks ...

Location-specific Internet services are predicated on the ability to identify the geographic position of IP hosts accurately. Fundamental to prior geolocation techniques is their reliance on landmarks with known coordinates whose distance from target hosts is intrinsically tied to the ability to make accurate location estimates. In this paper, we introduce a new lightweight framework for IP geo...

The arrangement of things in n-dimensional space is specified as Spatial. Spatial data consists of values that denote the location and shape of objects and areas on the earth’s surface. Spatial information includes facts such as location of features, the relationship of geographic features and measurements of geographic features. The spatial cognition is a primal area of study in various other ...
