We present some algorithms related to rings of Ore polynomials (or, briefly, Ore rings) and describe a computer algebra library for basic operations in an arbitrary Ore ring. The library can be used as a basis for various algorithms in Ore rings, in particular, in differential, shift, and q-shift rings.

We describe the design steps and final implementation of a MIMO OFDM prototype platform developed to enhance the performance of wireless LAN standards such as HiperLAN/2 and 802.11, using multiple transmit and multiple receive antennas. We first describe the channel measurement campaign used to characterize the indoor operational propagation environment,… (More)

We present eecient polynomial time algorithms that place bn=2c vertex guards which cover the surface of an n-vertex polyhedral terrain, and similarly, bn=3c edge guards which cover the surface of an n-vertex polyhedral terrain. The time complexity of both algorithms, dominated by the cost of nding a maximum matching in a graph, is O(n 3=2).

We present an optimal ¢´Òµ-time algorithm for the selection of a subset of the vertices of an Ò-vertex plane graph so that each of the faces of is covered by (i.e. incident with) one or more of the selected vertices. At most ÒÒ¾ vertices are selected, matching the worst-case requirement. Analogous results for edge-covers are developed for two different… (More)

The objective of this paper is to provide the theoretical background and illustrative examples for elastic buckling analysis of cold-formed steel members with general boundary conditions as implemented in the forthcoming update to CUFSM. CUFSM is an open source finite strip elastic stability analysis program freely distributed by the senior author. Although… (More)

–In this paper, the mooring dynamic loads and the motion responses of a large container ship in irregular waves with steady wind and current is investigated based on the commercial software AQWA. Comparisons between the time-history motion responses of a large container ship and the change of the mooring line tension in three different cases, non-mooring… (More)
