  1. Validation and downscaling of Advanced Scatterometer (ASCAT) soil moisture using ground measurements in the Western Cape, South Africa

    Validation and downscaling of Advanced Scatterometer (ASCAT) soil moisture using ground measurements in the Western Cape, South Africa

    Item type: Journal Article • Journal: South African Journal of Plant and Soil
    Satellite-based remote sensing of soil water content (SWC) is a promising technology for hydrological applications to overcome large spatiotemporal variabilities of SWC. This study investigated the performance of the Advanced Scatterometer (ASCAT) soil moisture product on METOP satellite (∼12.5 km...
  2. EQUATIONS OF BALANCE, HORIZONTAL DISTRIBUTIONS AND FOLIATION-VALUED SOLUTIONS

    EQUATIONS OF BALANCE, HORIZONTAL DISTRIBUTIONS AND FOLIATION-VALUED SOLUTIONS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Systems of second order partial differential equations of the form
  3. HORIZONTAL DISTRIBUTIONS ON SPACES OF FIBERS

    HORIZONTAL DISTRIBUTIONS ON SPACES OF FIBERS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Geometric methods for systems of partial differential equations and multiple integral problems in the calculus of variations lead naturally to differentiable manifolds that resemble fiber bundles but do not possess a structure group; in terms of local coordinates, π:B→Mn|(xi, qα)→(xi),...
  4. A THEOREM OF BÄCKLUND REVISITED

    A THEOREM OF BÄCKLUND REVISITED

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Bäcklund's theorem states that the most general contact transformation is an extended point transformation whenever both the number of independent variables and the number of dependent variables exceed one. A partial circumvention of Bäcklund's theorem is obtained by assigning each...
  5. ARE SYMMETRY GROUPS OF PDE RESTRICTED BY THE JET BUNDLE FORMULATION?

    ARE SYMMETRY GROUPS OF PDE RESTRICTED BY THE JET BUNDLE FORMULATION?

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Yesl Any equation of conservation of the form ∂x{P(∂xφ, ∂tφ) = ∂t{Q(∂xφ, ∂tφ) is shown to admit an infinite-dimensional, Abellan group of symmetries that is not a prolongation symmetry group. Explicit equations are given for the determination of the generators...
  6. NONLINEAR HOMOTOPY AND PRE-POINCARÉ LEMMAS

    NONLINEAR HOMOTOPY AND PRE-POINCARÉ LEMMAS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Most homotopies considered in the literature are linear homotopies of the form h i (λ) = λx i + (1—λ)y i , 0 ≤ λ ≤ 1. Although these prove to be adequate in most instances, they...
  7. EXPLICIT SOLUTIONS OF CLASSES OF EXTERIOR DIFFERENTIAL SYSTEMS

    EXPLICIT SOLUTIONS OF CLASSES OF EXTERIOR DIFFERENTIAL SYSTEMS

    Item type: Journal Article • Journal: Quaestiones Mathematicae
    Explicit solutions of certain exterior differential systems of degrees one and two are constructed on a star-shaped region of a differentiable manifold. A closed differential ideal that is generated by 1-forms that are solutions of an exterior differential is constructed...
  8. Seasonal differences in foraging dynamics, habitat use and home range size of Wahlberg’s epauletted fruit bat in an urban environment

    Seasonal differences in foraging dynamics, habitat use and home range size of Wahlberg’s epauletted fruit bat in an urban environment

    Item type: Journal Article • Journal: African Zoology
    Urbanization through the process of habitat loss and fragmentation affects ecosystems. Many species are no longer able to survive in these urban areas; however, there are some that have been able to persist and even thrive in these habitats. One...
  9. Roost temperature and fidelity of Wahlberg’s epauletted fruit bat, <em>Epomophorus wahlbergi</em>, in an urban environment

    Roost temperature and fidelity of Wahlberg’s epauletted fruit bat, <em>Epomophorus wahlbergi</em>, in an urban environment

    Item type: Journal Article • Journal: African Zoology
    Generally,Wahlberg’s epauletted fruit bat (Epomophorus wahlbergi) roost in trees or under the eaves of buildings. This study investigated the roosting dynamics of E. wahlbergi in the urban environment of Pietermaritzburg, South Africa. To determine roost fidelity bats were radiotracked to...
