Minimal Hulls, Null Hulls, and Currents
2021In this chapter we initiate the study of minimal hulls and null hulls of compact sets in Euclidean spaces. These hulls are defined by the maximum principle for minimal and null plurisubharmonic functions, in analogy to the classical polynomial and plurisubharmonic hulls of complex analysis.

IET 4th European Conference on Visual Media Production (CVMP 2007), 2007
The visual hull is widely used as a proxy for novel view synthesis in computer vision. This paper introduces the safe hull, the first visual hull reconstruction technique to produce a surface containing only foreground parts. A theoretical basis underlies this novel approach which, unlike any previous work, can also identify phantom volumes attached to

CARTESIAN CLOSED TOPOLOGICAL HULLS AS INJECTIVE HULLS [PDF]
Quaestiones Mathematicae, 1986 Abstract It is shown that (concretely) Cartesian closed topological hulls can be characterized as injective hulls in a rather natural setting. The characterization of locale hulls as injective hulls in the category of (meet-) semilattices by Bruns & Lakser and Born & Kimura constitutes a special case.

Applied Categorical Structures, 2001
For each concrete category (K,U) an extension LIM(K,U) is constructed and under certain 'smallness conditions' it is proved that LIM(K,U) is a solid hull of (K,U), i.e., the least finally dense solid extension of (K,U). A full subcategory of Top2 is presented which does not have a solid hull.

Aflatoxins in cottonseed hulls
Journal of the American Oil Chemists' Society, 1970AbstractPrevious studies indicate that aflatoxins were found in laboratory‐prepared hulls from cottonseed which contained aflatoxins. However, no aflatoxins were found in hulls commercially processed from cottonseed containing aflatoxins, crops of 1964 and 1965, which were analyzed in our laboratory.
