Building Mixed Societies of Animals and Robots
This article presents the European project LEURRE aiming to study, model and control mixed societies of animals and robots. The robotic part discusses general ideas on the design and implementation of robots to be used together with groups of animals. After a presentation of the project, the implications on the special requirements imposed on the robot is discussed. The design process of the ro...
متن کاملDynamically Supported Trench Topography
A viscous flow model of a subduction zone is used to calculate the near-trench deformation and topography of the overriding plate in response to tectonic and buoyancy forces. The tectonic force, which is associated with global plate motion, arises from subduction of a cold oceanic lithosphere that shears the overriding lithosphere along the contact between the two plates. The buoyancy force ari...
متن کاملFrom trench fever to endocarditis.
The case of a 44 year old woman with infective endocarditis due to Bartonella quintana, an organism long recognised to cause a condition known as trench fever, is reported. This case illustrates the lengthy differential diagnosis of "culture negative" endocarditis. In addition the presence of serological cross reactivity of Bartonella spp and Chlamydia spp demonstrates the potential for misdiag...
متن کاملTrench stability in cohesive soil
Trench is connected to very narrow and deep excavation filled with bentonite suspension. This paper presents estimation of its stability in cohesive soil. The stability is assessed by two calculation methods. The first involves the equilibrium of forces acting on the rigid wedge. The second one includes numerical calculations conducted in Plaxis 3D Foundations. A few examples having different d...
متن کاملRecent cases of trench foot.
Two cases of cold injury to the lower extremities, 'trench foot', are presented. The management is essentially conservative, but in cases of severe damage, particularly in elderly people, amputation must be advised.
