Mumps presents a serious threat to public health in China. We conducted a descriptive analysis to identify the epidemiological characteristics of mumps in Shandong Province. Spatial autocorrelation and space-time scan analyses were utilized to detect spatial-temporal clusters. From 2005 to 2014, 115745 mumps cases were reported in Shandong, with an average male-to-female ratio of 1.94. Mumps oc...
There has been recent interest in the segmentation of images by thresholding. We present several model based algorithms for threshold selection. We concentrate on the important two population univariate case when an image contains an object and background. However the methods are applicable to multispectral k-population images. We show how the main ideas behind two important nonspatial threshol...
Previous studies suggest that management intensity zoning systems, such as the triad approach, could allow Canada’s forest industry to maintain or increase timber harvest levels while simultaneously reducing its environmental impact. In most such studies, the zones are exogenously specified. In this study, we use a linear programming model to endogenously allocate forest land to management inte...
Spatial diversity is an inherent nature of wireless communications. This nature can be exploited to make communications more reliable by Multiple-Input-Multiple-Output (MIMO). However the use of multiple co-located antennas is constrained by the dimensions of modern devices. To overcome this drawback cooperative relaying shares antennas between different network nodes thus realizing a Virtual a...
Spatial allocation models represent decision processes of allocating discrete spatial units (e.g., land parcels and grid cells) to particular uses under the assumption that attributes of those units are unchanged over time and all decisions are made at one time. Given forecasts of spatial attributes, this assumption may be dropped, though spatial and temporal considerations will be highly inter...
