Many applications of IP geolocation can benefit from geolocation that is robust to adversarial clients. These include applications that limit access to online content to a specific geographic region and cloud computing, where some organizations must ensure their virtual machines stay in an appropriate geographic region. This paper studies the applicability of current IP geolocation techniques a...
are measured on people who live within defined geographic regions. The measurements are then clustered within regions at each time point, but also comprise longitudinal measurements on each person across time. These data might be expected to have two potential sources of correlation, due to the similarity of measurements within and between the people in a region across time. While the former ex...
Two previously published papers (Vaver and Koehler, 2011, 2012) describe a model for analyzing geo experiments. This model was designed to measure advertising effectiveness using the rigor of a randomized experiment with replication across geographic units providing confidence interval estimates. While effective, this geo-based regression (GBR) approach is less applicable, or not applicable at ...
Benthic indices are typically developed independently by habitat, making their incorporation into large geographic scale assessments potentially problematic because of scaling inequities. A potential solution is to establish common scaling using expert best professional judgment (BPJ). To test if experts from different geographies agree on condition assessment, sixteen experts from four regions...
The dynamism of sociogeographic and historical processes and trends represents a key factor in the creation and uniformity of regions, and in their image and perception in the eyes of the publ ic and scholars. As a basic geographic concept, a region is the result of al l preceding and actual spatial relations arising from natural conditions, and those arising from pol itical , administrative an...
-We describe the current status of an ongoing research effort to develop a geographic information system based on quadtrees. Quadtree encodings were constructed for area, point and line features for a small area in Northern California. The encoding used was a variant of the linear quadtree. The implementation used a B-tree to organize the list of leaves and allow management of trees too large t...
abstract: in this thesis, we focus to class of convex optimization problem whose objective function is given as a linear function and a convex function of a linear transformation of the decision variables and whose feasible region is a polytope. we show that there exists an optimal solution to this class of problems on a face of the constraint polytope of feasible region. based on this, we dev...

Grassed waterways placed in high water flow zones substantially reduce erosion in agricultural fields. A recent study proposed a statistical model for waterway planning for a farm in the Outer Bluegrass physiographic region of Kentucky. The logistic regression model identified where channel erosion was likely to occur based on elevation-derived terrain attributes. The objective of this study wa...
Little is known about the strains of Trypanosoma cruzi circulating in Central America and specifically in the most important vector in this region, Triatoma dimidiata. Approximately six million people are infected with T. cruzi, the causative agent of Chagas disease, which has the greatest negative economic impact and is responsible for ~12,000 deaths annually in Latin America. By international...
