PSR B1828-11: a precession pulsar torqued by a quark planet? [PDF]

open access: yes, 2006
The pulsar PSR B1828-11 has long-term, highly periodic and correlated variations in both pulse shape and the rate of slow-down. This phenomenon may provide evidence for precession of the pulsar as suggested previously within the framework of free ...

GWR-PM - Spatial variation relationship analysis with Geographically Weighted Regression (GWR) - An application at Peninsular Malaysia

open access: yesIOP Conference Series: Earth and Environmental Science, 2016
GWR-PM has been developed exclusively for decision makers in Peninsular Malaysia and the purpose is to provide them with additional flexibility in analysing spatial variation. While GWR extension analysis in ArcMap application has a universal coordinate system, GWR-PM is specifically designed with Peninsular Malaysia's coordinate system of Kertau RSO ...

Spatial effect of factors affecting household CO2 emissions at the provincial level in China: a geographically weighted regression model

open access: yesCarbon Management, 2018
The size of household CO2 emissions (HCE) has drawn increasing attention recently. Due to differences in geographical location, traditional models do not provide a valid basis or countermeasures for CO2 emissions reduction in different provinces, leading
