Applied Categorical Structures, 1994
In the beginning of this very interesting article (which is the first part of an overview of topological descent theory) an elementary topological approach to Grothendieck's idea of descent is given. The authors work also with the subcategories \({\mathcal E}(B)\) of bundles over \(B\) given by a suitable class \({\mathcal E}\) of continuous maps (i.e.,

Finding the convex hull facet by facet
Journal of Algorithms, 1985An algorithm for producing the facial lattice of a d-dimensional polytope is given. The running time of the algorithm is \(O(ndl+d^ 5l \log n)\) for a simplicial polytope and \(\Omega\) (fd! d) for the general polytope, where n is the number of vertices of the polytope, f is the number of its facets, and l is the number of lattice arcs.

The clique partitioning problem: Facets and patching facets
Networks, 2001AbstractThe clique partitioning problem (CPP) can be formulated as follows: Given is a complete graph G = (V, E), with edge weights wij ∈ ℝ for all {i, j} ∈ E. A subset A ⊆ E is called a clique partition if there is a partition of V into nonempty, disjoint sets V1,…, Vk, such that each Vp (p = 1,…, k) induces a clique (i.e., a complete subgraph), and A

Journal of Theoretical Politics, 2014
This paper proposes four concepts of exploitation that encapsulate common uses of the word in social interactions: unfair advantage, unequal exchange, using persons as means, and free-riding. It briefly discusses how these concepts appear in the literature (the first two are prominent in Roemer’s classical work), and then examines how these forms of ...

International Journal of Bifurcation and Chaos, 2015
There are many ways that a person can encounter chaos, such as through a time series from a lab experiment, a basin of attraction with fractal boundaries, a map with a crossing of stable and unstable manifolds, a fractal attractor, or in a system for which uncertainty doubles after some time period.

Adaptivity is one of the key requirements of today's information systems. It is used in various areas which may range from control and operating systems to networks, from robotics to intelligent systems, from multimedia to information retrieval and Web Services. Essentially, it is related to changes performed in the systems at run-time.

Facet Folders are a visualization and interaction concept for filtering collections of personal data. Although visually derived from the ubiquitous folder hierarchies of file managers, Facet Folders explicitly expose the faceted metadata used for filtering.

The force that drives fundamental changes in security is change in the use of information technology. To show how the environment impinges on security requirements and the selection of security mechanisms we compare familiar closed systems and emerging open systems.

Objective: To clarify the role of ‘melancholia’ in psychiatric nomenclature.Most clinicians and researchers are convinced that the syndrome currently termed major depressive disorder encompasses multiple subgroups that differ meaningfully in phenomenology, natural history, treatment response, and pathophysiology.

Classification schemes are needed to catalog the growing numbers of images. Facets are an important technique from library science that can help to more effectively represent visual concepts.
