New Terms of Envatment

The argument against skepticism relying on content externalism, which was made famous by Hilary Putnam, has been considered inconclusive by many philosophers. However, some believe that this argument has precluded the possibility of skeptical hypotheses. These hypotheses typically are fictional scenarios where a deceptive power makes your experiences indistinguishable from those you would have if you were not in such a scenario, making most of your justified belief false. Some philosophers, such as Anthony Brueckner and Jon Altschul, have taken this problem seriously and, in response to Putnam, have developed an alternative to the argument from ignorance: the piecemeal fashion strategy. I wish to defend, contra Brueckner and Altschul, the idea that some skeptical hypotheses remain untouched by content externalism, making the piecemeal fashion strategy obsolete.

A multiple-building diffraction attenuation function expressed in terms of UTD coefficients for microcellular communications

This work presents an explicit formulation for multiple- edge diffraction for mobile radiowave propagation in terms of uniform theory of diffraction (UTD) coefficients when a spherical incident wave is considered. This solution can be used in an UTD context and sharply reduces the computing time over existing formulation. Results can be applied in the planning of microcellular systems
