In this paper, an entanglement criterion for states in infinite dimensional bipartite quantum systems is presented. We generalize some of separability criterion that was recently introduced by Wu and Anandan in (Phys. Lett. A, 2002, 297, 4-8) to infinite dimensional bipartite quantum systems. In addition, we give an example aimed to illustrate the application of the theorem.

In the present work, damage propagation in thermoplastic composite laminates subjected to quasi-static tensile loading was numerically simulated using different models. The simulation performed commercial finite element suite LS-Dyna, where various material models were evaluated based on their ability simulate behavior. More specifically, Tsai-Wu failure criteria (MAT_055), progressive modeling...

Recently, neuroscience perspectives on human learning have drawn increasing interest among researchers in education (Schrag, 2011). Many researchers, particularly in science and mathematics education, have highlighted the utility of integrating a neuroscience or cognitive–science perspective into science andmathematics learning (e.g. Anderson, 1983, 1997, 2009; Anderson & Contino, 2013; Duncan ...

Machining of Nomex® honeycomb materials is the biggest challenge in industry because complex forms and geometry structure. The latter characterized by a low density with orthotropic mechanical behavior. thin walls composite structure make shaping this material very difficult. Studying interactions between cutting tool material, forces, chip formation allow to understand machining process honeyc...

Evolution of materials, following the design requirements of special structures, has shifted interest towards development of composite members able to meet strength requirements “tailored” to specific applications. These members can provide appropriate, more cost effective structures, however absence of generic design guidelines raise constraints towards derivation of optimized structures. Reli...

Polimer matrisli tabakalı kompozit malzemelerin bileşenlerinin dayanım yönünden çok farklı olması bu malzeme grubunun hasar analizlerini zorlaştırmaktadır. Tabakalı kompozitlerin analizleri için önerilen birçok ölçütü bulunmaktadır. Bu çalışmada iki yönde düzlemsel yayılı yüke ve bir yük ile kayma yüküne maruz S-cam lifi/epoksi karbon Tsai-Wu Puck ölçütüne göre hasarı araştırılmıştır. Birçok yü...

Conventional surface integral equation (SIE)-based characteristic mode formulation for the patch antenna structure with a finite substrate is susceptible to spurious (nonphysical) modes due dielectric part. To avoid contamination of modes, we propose novel generalized eigenvalue based on electric field equation-coupled Poggio–Miller–Chang–Harrington–Wu–Tsai eq...

We report a new nematic liquid crystal (LC) mixture with an ultra-low rotational viscosity (γ1 = 53.4 mPas @ 35°C), relatively high birefringence (Δn ≈0.15), and moderate dielectric anisotropy (Δε = −2.80 @ 35°C). When employed in a liquid-crystal-on-silicon (LCoS) projector with RGB light-emitting diodes (LEDs), a sub-millisecond response time is obtained without the need for complicated overd...
