In the present age of globalization, technology-revolution and sustainable development, the presence of seasonality in tourist arrivals is considered as a key policy issue that affects the global tourism industry by creating instability in the demand and revenues. The seasonal component in a time-series distorts the prediction attempts for policy-making. In this context, it is quintessential to...

Not withstanding the commonly-held wisdom that “you can’t determine the absolute location of earthquakes using the double-difference method”, you can. We present a way of visualizing double-difference data, and use it to show how differential arrival time data can, in principle, be used to determine the absolute locations of earthquakes. We then analyze the differential form of Geiger’s Method,...

Abstract Maximum permissible errors (MPEs) are an important measurement system specification and form the basis of periodic verification a system’s performance. However, there is no standard methodology for determining MPEs, so when they not provided, or suitable procedure performed, it unclear how to generate appropriate value with which verify system. Whilst simple approach might be take many...

The use of land surface temperature and vertical temperature profile data from Moderate Resolution Imaging Spectroradiometer (MODIS), to estimate high spatial resolution daily and monthly maximum and minimum 2 m above ground level (AGL) air temperatures for regions with limited in situ data was investigated. A diurnal air temperature change model was proposed to consider the differences between...

Expansion of human activities causes dispersion of pollutants in the subsurface environment. The fate and movement of dissolved substances in soils and groundwater has generated considerable interest out of concern for the quality of the subsurface environment. Many analytical solutions for partial differential equations exist in soil science. Numerical solutions are more general, and often mor...

BACKGROUND/HYPOTHESIS The arthritic glenoid is typically in retroversion and restoration to neutral version is recommended. While a method for measurement of glenoid version using axial computed tomography (CT) has been reported and has been widely accepted, its accuracy and reproducibility has not been established. METHODS In 33 patients scheduled for shoulder arthroplasty, glenoid version a...

Tidal datums are key components in NOAA’s Vertical Datum transformation project (VDatum). In this paper, we propose a statistical interpolation method, derived from the variational principle, to calculate tidal datums by blending the modeled and the observed tidal datums. Through the implementation of this statistical interpolation method in the Chesapeake and Delaware Bays, we conclude that th...
