We study aspects of chaos and thermodynamics at strong coupling in a scalar model using LCT numerical methods. find that our eigenstate spectrum satisfies Wigner-Dyson statistics the coefficients describing eigenstates basis satisfy Random Matrix Theory (RMT) statistics. At weak coupling, though bulk states RMT statistics, we several scar as well. then use these chaotic to compute equation stat...

The new additive/subtractive technology (Shape Deposition Manufacturing) enhances Solid Freeform Fabrication (SFF) capability in producing near net-shape surface finish. This technology also builds parts in fewer layers compared with conventional layered manufacturing technology. However, to decompose a part into freeform layers usually requires expensive geometric computation. Also, to plan bu...

It is suggested that many-body quantum chaos appears as the spontaneous symmetry breaking of unitarity in interacting systems. has been shown level statistics, probed by spectral form factor (SFF) defined $K(\ensuremath{\eta},t)=\ensuremath{\langle}|\mathrm{Tr}exp(\ensuremath{-}\ensuremath{\eta}H+itH){|}^{2}\ensuremath{\rangle}$, dominated a diffuson-type mode field theory analysis. The key fin...

In this paper we study a problem of 3D scene reconstruction from a set of differently focused images, also known as the shape from focus (SFF) problem. Existing shape from focus methods are known to produce unstable depth estimates in areas with poor texture and in presence of strong highlights. So in this work we focus on the robustness of 3D scene structure recovery. We formulate a shape from...

To enhance the hemocompatibility of silk fibroin fabric as biomedical material, polyelectrolytes architectures have been assembled through the layer-by-layer (LbL) technique on silk fibroin fabric (SFF). In particular, 1.5 and 2.5 bilayer of oppositely charged polyelectrolytes were assembled onto SFF using poly(allylamine hydrochloride) (PAH) as polycationic polymer and poly(acrylic acid) (PAA)...

A continuous path is one of the most important requirements for solid freeform fabrication (SFF) based on welding. This paper proposes a method for torch path planning applicable to SFF based on welding with an emphasis on minimum human intervention. The suggested approach describes a method based on the subdivision of a two-dimensional (2-D) polygonal section into a set of monotone polygons to...

A paradigm shift is taking place in medicine from using synthetic implants and tissue grafts to a tissue engineering approach that uses degradable porous material scaffolds integrated with biological cells or molecules to regenerate tissues. This new paradigm requires scaffolds that balance temporary mechanical function with mass transport to aid biological delivery and tissue regeneration. Lit...

In the present work, a photopolymerized urethane-based poly(ethylene glycol) hydrogel is applied as a porous scaffold material using indirect solid freeform fabrication (SFF). This approach combines the benefits of SFF with a large freedom in material selection and applicable concentration ranges. A sacrificial 3D poly(ε-caprolactone) structure is generated using fused deposition modeling and u...

Shape Deposition Manufacturing (SDM) is a solid freeform fabrication (SFF) process that incrementally builds up complex parts by systematically combining material additive processes with material removal processes. The advantages of each type of process are thus combined such that novel structures can be fabricated with SDM that could not be practically fabricated with either material additive ...
