For the problem of homogeneity of variances, a new generalized test variable is given and the generalized p-value based on the test variable is derived. The proposed generalized p-value is proved to have exact frequency property, and it is also invariant under the group of scale transformation.

The availability of spatial databases and widespread use of geographic information systems has stimulated increasing interest in the analysis and modelling of spatial data. Spatial data analysis focuses on detecting patterns, and on exploring and modelling relationships between them in order to...

Areas of water shortage comprise many smaller sub-areas into which water is transported from external sources. Fairness and efficiency of distribution are overriding principles. Each local area requires adequate water for community and ecological purposes as well as a supply sufficient to...

Revenue management for transportation infrastructure projects is challenging due to the huge amount of capital involved and the deep uncertainty inherent in long service lifetimes. Public-private partnerships (PPPs) provide a way for the public sector to acquire financial resources and transfer...

Antioxidation responses of maize roots and leaves to water deficit and rewatering under partial root-zone irrigation (PRI) were investigated using a pot system. Plants were cultured using three irrigation methods, i.e. conventional irrigation (CI), alternate PRI (APRI) and fixed PRI (FPRI) with...
