This study proposes a design of low-profile ultra wide-band cylindrical antenna array with plus/minus 45-degree dual polarization. The proposed compact produces an omnidirectional radiation pattern in the azimuth plane to cover all directions. It consists $20\times 4$ dual-polarized elements within diameter 131 mm and heig...

Currently document collaboration typically proceeds using tools such as CVS or vendor-specific Computer Supported Collaborative Work (CSCW) and Electronic Meeting (EM) messaging systems. Both regulate essentially asynchronous loosely coupled collaboration. The prime disadvantages of these technologies are that often documents are checked out or distributed in their entirety and that human inter...

DynEarthSol3D (Dynamic Earth Solver in Three Dimensions) is a flexible, open-source finite element solver that models the momentum balance and the heat transfer of elasto-visco-plastic material in the Lagrangian form using unstructured meshes. It provides a platform for the study of the long-term deformation of earth's lithosphere and various problems in civil and geotechnical engineering. Howe...

We present a novel approach to probabilistic description logic programs for the Semantic Web in which disjunctive logic programs under the answer set semantics are tightly coupled with description logics and Bayesian probabilities. The approach has several nice features. In particular, it is a logic-based representation formalism that naturally fits into the landscape of semantic web languages....

This paper presents a mechanism enabling robot team members to share sensor information to achieve tightly-coupled cooperative tasks. This approach, called ASyMTRe, is based on a distributed extension of schema theory that allows schema-based building blocks to be interconnected in many ways, regardless of whether they are on the same or different robots. The inputs and outputs of schema are la...
