Millions of containers are stowed every week with goods worth billions of dollars, but container vessel stowage is an all but neglected combinatorial optimization problem. In this paper, we introduce a model for stowing containers in a vessel bay which is the result of probably the longest collaboration to date with a liner shipping company on automated stowage planning. We then show how to sol...

We describe a methodology for analyzing geographical data using the techniques of (1) qualitative geometric abstraction and (2) ontological analysis of geographic features. The first technique is a bottom-up approach to extract qualitative spatial relations from geographic representations (raster or vector) while the second technique is a top-down approach to determine which qualitative relatio...

For mathematicians, modern philosophy of mathematics may seem somewhat puzzling. In the late nineteenth and early twentieth centuries, the borders between philosophy and mathematics were porous. Influential mathematicians like Poincaré, Brouwer, Ramsey, and Hilbert wrote extensively on philosophical topics, and philosophers like Russell, Wittgenstein, and Quine made serious philosophical use of...

Analysis of sea-level observations demonstrates that Typhoons Mawar (2017) and Mangkhut (2018) induced seiches in both Dapeng Bay Daya near Shenzhen China, with periods varying from about 3.5 to 4.0 h. Typhoon also generated a period 1.2 Seiches such the two bays have not been reported past. In this study, we investigate main processes affecting over these coastal waters using nested-grid ocean...

Aureococcus anq~ha&erens is a picoplanktonic alga that since 1985 has bloomed in coastal embayments of the western mid-Atlantic, ranging from Narragansett Bay, Rhode Island, to Barnegat Bay, New Jersey, with greatest incidence of rccurrencc in Long Island bays, New York. Blooms of this small alga, referred to as “brown tide,” can persist for several months during late spring and summer at densi...
