Synthesis of moving and beating moiré shapes

Jürgen Brugger, Roger Hersch, Thomas Walger

The present invention proposes a method for producing an authenticable moiré shape that simultaneously moves and shows a beating effect. The method relies on a combination of the 1D or the 2D moiré and the level line moiré. When tilting a compound showing ...

WOK: Statistical Program Slicing in Production

James Richard Larus, Bogdan-Alexandru Stoica

Dynamic program slicing can significantly reduce the amount of code developers need to inspect by focusing only on program statements relevant to their investigation. However, this technique is still not ready for production-level use either in terms of ru ...

Room temperature concurrent formation of ultra-dense arrays of ferroelectric domain walls

Nava Setter, Alexander Tagantsev, Petr Yudin, Ludwig Feigl, Mahamudu Mtebwa, Konstantin Shapovalov

Properties of ferroelectric domain walls are attractive for future nano- and optoelectronics. An important element is the potential to electrically erase/rewrite domain walls inside working devices. Dense domain wall patterns, formed upon cooling through t ...

Influence of flexoelectric coupling on domain patterns in ferroelectrics

Nava Setter, Alexander Tagantsev, Petr Yudin

Using Ginzburg-Landau theory and two-dimensional (2D) phase field simulations, we analyze the influence of flexoelectric coupling on the domain patterns in ferroelectrics. The phase field simulations predict that a high strength of the flexoelectric coupli ...

LDPC Codes for 2D Arrays

Mohammad Amin Shokrollahi, Yuval Cassuto

Binary codes over 2D arrays are very useful in data storage, where each array column represents a storage device or unit that may suffer failure. In this paper, we propose a new framework for probabilistic construction of codes on 2D arrays. Instead of a p ...

1D and 2D arrays of coupled photonic crystal cavities with a site-controlled quantum wire light source

Elyahou Kapon, Alok Rudra, Benjamin Dwir, Pascal Gallo, Kirill Atlasov, Clément William Tendaï Jarlov, Milan Calic

We investigated experimentally 1D and 2D arrays of coupled L3 photonic crystal cavities. The optical modes of the coupled cavity arrays are fed by a site-controlled quantum wire light source. By performing photoluminescence measurements and relying on near ...
