So far, many types of location models have been developed to find optimal spatial patterns according to different spatial metrics such as cost, coverage and availability.  The initial focus of these models is on the location availability of service providers and demand estimates, and some of these models are within the framework of multi-objective programming models.  After the advent of scienc...

Abstract Airborne gravimetry is an efficient and reliable method to obtain information on the gravity field, fundamental field modelling, geoid determination, flood risk mapping. In evaluation utilization of estimates, two measures are importance, namely accuracy spatial resolution. These related one another through filtering required suppress observational noise. As strapdown inertial measurem...

Abstract Background The use of statistical methods to quantify the strength migratory connectivity is commonplace. However, little attention has been given their sensitivity spatial sampling designs and scales inference. Methods We examine sources bias imprecision in most widely used methodology, Mantel correlations, under a range plausible regimes using simulated populations. Results As correl...

A general simulation procedure is described to validate model fitting algorithms for complex likelihood functions that are utilized in periodic cancer screening trials. Although screening programs have existed for a few decades, there are still many unsolved problems, such as how age or hormone affects the screening sensitivity, the sojourn time in the preclinical state, and the transition prob...
