In this paper we propose a tensor based description of the Bézier Shape Deformation (BSD) algorithm, denoted T-BSD. The BSD algorithm is a well-known technique, based on the deformation of a Bézier curve through a field of vectors. A critical point in the use of real-time applications is the cost in computational time. Recently, the use of tensors in numerical methods has been increasing becaus...

Let Ω be a bounded Lipschitz domain in R. The CauchyGreen, or metric, tensor field associated with a deformation of the set Ω, i.e., a smooth enough orientation-preserving mapping Θ : Ω → R, is the n× n symmetric matrix field defined by ∇Θ (x)∇Θ(x) at each point x ∈ Ω. We show that, under appropriate assumptions, the deformations depend continuously on their Cauchy-Green tensors, the topologies...
Methods: Suppose Ø:S1->S2 is a map from the surface S1 to the surface S2, we define the derivative map of Ø is the linear map between the tangent spaces, dØ:TM(p)->TM(Ø(p)), induced by the map. Let J be the derivative map and define the deformation tensor as S=(JTJ)1/2. Instead of analyzing shape change based on the eigenvalues of the deformation tensor, we consider a new family of metrics, the...

seismic retrofit strategies have been developed in the past few decades following the introduction of new seismic provisions and the availability of advanced materials and methods. it can be observed that new approaches to deal with more lateral forces are more innovative and more energy absorbent. in line with this, there is a growing trend toward the use of steel shear walls as a system with ...
Background: Staphylococcus lugdunensis is Gram-positive cocci of the staphylococcaceae family. S. lugdunensis despite having a clotting factor (wall coagulase), was classified in the coagulase negative staphylococcus group (CoNS) for lack of free coagulase. Although this bacterium is part of the human normal flora, in terms of virulence, S. lugdunensis is in second place after S. aureus. S. lug...
