In this paper, we develop a multiscale method for solving the Signorini problem with heterogeneous field. The is encountered in many applications, such as hydrostatics, thermics, and solid mechanics. It well-known that numerically requires fine computational mesh, which can lead to large number of degrees freedom. aim work new hybrid based on framework generalized finite element (GMsFEM). const...

Abstract Archimedes, the founder of statics and hydrostatics, in his mathematics physics studies, created methods related to inventions new machines, for example, method mechanical theorems based on lever invention. He also used principles decomposition replication underlying heat ray invention, these two permeate work. Analysis Archimedes’ work shows how he was perhaps first use methodically a...

Burgessia bella is a characteristic Burgess Shale arthropod (508 Ma), but the unusual preservation of its telson in both straight and bent modes leads to contradictory interpretations of its function. A reinvestigation of the fossil material, including burial attitudes, combined with a comparison with the decay sequence and mechanics of the telson in living Limulus, demonstrates that the telson...

This new research considers the 3 main motions of moored floater (surge, heave and pitch) in head waves it explores ways to estimate systematic uncertainties on RAOs, 2 other metrics for these signals. Based linear hydrostatics potential flow theory, simple relations can be found that bind characteristics a floater. These are transformed using algebra express how uncertainty bias tested system ...
