Creating Servlets with Intellij V8

This paper describes how to configure servlets with Intellij version 8. The GUI intensive approach to enterprise Java has classically led to configuration issues that require both a deployment environment and a lengthy IDE setup. Students (and, indeed, seasoned professionals) can find this confusing. The article is both a case study and a tutorial on simple enterprise Java configuration and dep...

Movable (n4) Configurations

An (nk) configuration is a collection of points and straight lines, usually in the Euclidean plane, so that each point lies on k lines and each line passes through k points; such a configuration will be called symmetric if it possesses non-trivial geometric symmetry. Although examples of symmetric (n3) configurations with continuous parameters are known, to this point, all known connected infin...

Priestley duality for N4-lattices

We present a new Priestley-style topological duality for bounded N4-lattices, which are the algebraic counterpart of paraconsistent Nelson logic. Our duality differs from the existing one, due to Odintsov, in that we only rely on Esakia duality for Heyting algebras and not on the duality for De Morgan algebras of Cornish and Fowler. A major advantage of our approach is that for our topological ...

Dualities for modal N4-lattices

We introduce a new Priestley-style topological duality for N4-lattices, which are the algebraic counterpart of paraconsistent Nelson logic. Our duality differs from the existing one, due to S. Odintsov, in that we only rely on Esakia duality for Heyting algebras and not on the duality for De Morgan algebras of Cornish and Fowler. A major advantage of our approach is that we obtain a simple desc...
