Tissue-level characterization of deformation dynamics is crucial for understanding organ morphogenetic mechanisms, especially the interhierarchical links among molecular activities, cellular behaviors and tissue/organ morphogenetic processes. Limb development is a well-studied topic in vertebrate organogenesis. Nevertheless, there is still little understanding of tissue-level deformation relati...

A quarter-circular arc piezoelectric Vibration energy harvester (VEH) based on nonlinear geometry is proposed with both bending moment and torque deformation mode, so it can effectively absorb multidirectional vibration at the same resonance frequency. The theoretical model of VEH established to study frequency output voltage. In order demonstrate multi-directional performance VEH, stress distr...

  Omni directional mobile robots have been popularly employed in several applications especially in soccer player robots considered in Robocup competitions. However, Omni directional navigation system, Omni-vision system and solenoid kicking mechanism in such mobile robots have not ever been combined. This situation brings the idea of a robot with no head direction into existence, a comprehensi...

We consider multifunctions acting between two linear normed spaces and having closed convex images. Approximations are considered which serve as an expansion of it. Generalized delta theorems for random sets in in nite dimensions are shown using those approximations. Furthermore, univalued, resp. Castaing representations of the multifunction are constructed with (higher order) di erentiability ...

Wire arc additive manufacturing achieves high efficiency and low costs by using a melting wire for directional depositions. Thermal analyses the finite element method have been applied to predict residual stress deformation of fabricated parts. For Ni-based alloy production, predicting solidification microstructure evolution with segregation is needed in order design precise heat treatment proc...

Traditional fabrication methods of architectural ceramics seek to minimize plastic deformation during wet-processing by prioritizing sectional consistency. Adapting thickness is critical for improving material performance address localized functional requirements. Functionally Graded Additive Manufacturing (FGAM) enables a design-to-production process where profiles can be designed achieve targ...

The paper studies convergence properties of numerical optimization algorithms using the natural idea of searching in several directions and where one-processor computation is assumed. Global convergence theorems (with exact arithmetic) are proved for two classes of "descent" methods in IR n and for one class of such methods in Hilbert spaces in the framework of unconstrained problems and where ...

Martensitic crystals which can undergo a cubic to tetragonal phase transformation have a nonconvex energy density with three symmetry-related, rotationally invariant energy wells. We give estimates for the numerical approximation of a first-order laminate for such martensitic crystals. We give bounds for the L2 convergence of directional derivatives in the “twin” plane, for the L2 convergence o...

An object-oriented approach to the analysis and design of metal forming and directional solidi cation processes is presented. A number of speci c ideas are introduced on how a deformation or a solidi cation process can be partitioned into subproblems that can be independently developed and tested in the form of class hierarchies. Class development based on mathematical and/or physical arguments...
