We consider the scattering of an electromagnetic time harmonic plane wave by very thin obstacles. In this lecture we will restrict ourselves to the scattering of an Epolarized electromagnetic field by a perfectly conducting infinite cylinder having an open arc in R as cross section. We further allow the possibility that one side of the cylinder is coated with a dielectric material. This leads t...

Overhead due to the movement of user data in the end-system network I/O processing path at high speeds is significant, and has limited the use of Internet protocols in interconnection networks, and the Internet itself -especially where high bandwidth, low latency, and/or low overhead are required by the hosted application. This document examines this overhead, and addresses an architectural, IP...

Deoxyribonucleic Acid or DNA computing has emerged as an interdisciplinary field that draws together chemistry, molecular biology, computer science, and mathematics. From the DNA computing point of view, it has been proven that it is possible to solve weighted graph problems by exploiting some characteristics of DNA such as length, concentration, and melting temperature. In this paper, we prese...

In this paper, we present a problem in international shipping which combines the ship routing problem with inventory considerations. A fleet of ships is responsible for the transportation of a given commodity between a supply port and the demand ports. Their routes should be selected so that the total transportation cost and the inventory cost is minimized. Although a generic mixedinteger progr...

This paper discusses a number of problems associated with the widely accepted analysis of differential object marking (DOM) as reflecting the semantic markedness of highly individuated (definite and/or animate) direct objects. Firstly, such an account is in conflict with established notions of transitivity which take a typical object to be highly affected, since affectedness can be shown to cor...
