In previous work we have shown the existence of a dynamical horizon or marginally trapped tube (MOTT) containing a given strictly stable marginally outer trapped surface (MOTS). In this paper we show some results on the global behavior of MOTTs assuming the null energy condition. In particular we show that MOTSs persist in the sense that every Cauchy surface in the future of a given Cauchy surf...

Irrigation land suitability assessment and mapping play an imperative role for sustainable utilization of scarce physical land resources. The objectives of this study were to prepare spatial data base of physical land resources for irrigated agriculture and to assess land suitability for irrigation and developing suitable area map for the study area. The study was conducted at Fogera catchment,...

ABSTRACT The global visibility of a singularity as an end state the gravitational collapse spherically symmetric pressureless cloud is investigated. We show existence non-zero measured set parameters: total mass and initial mean density collapsing cloud, giving rise to physically strong globally visible for fixed velocity function. such indicates that stable under small perturbation in data cau...

We present a method for constructing dependent Dirichlet processes. The new approach exploits the intrinsic relationship between Dirichlet and Poisson processes in order to create a Markov chain of Dirichlet processes suitable for use as a prior over evolving mixture models. The method allows for the creation, removal, and location variation of component models over time while maintaining the p...

This study mapped out the agricultural land suitability in Zaria using Geospatial Techniques (GT) with a view to highlight areas of improvement production enhance food security. The Agricultural Land Suitability (ALS) is fitness specific crop. ALS selects that best suits and supports crop optimal yield, by matching qualities crop’s requirements; hence increasing productivity per unit at minimum...
