For a layered probabilistic shaping (PS) scheme with a general decoding metric, an achievable rate is derived using Gallager’s error exponent approach. Several instances for specific decoding metrics are discussed, including bit-metric decoding, interleaved coded modulation, and hard-decision decoding. It is shown that important previously known achievable rates can also be achieved by layered ...

This paper considers both an object-oriented multi-layered approach to application design as well as the programming system which implements the methodology presented. The layered approach was motivated by the need for providing support for di erent kinds of knowledge representation in the application design process and sharing the same object base between software components using these repres...

Modeling, design and fabrication of tissue scaffolds with intricate architecture, porosity and pore size for desired tissue properties presents a challenge in tissue engineering. This paper will present the details of our development in the design and fabrication of the interior architecture of scaffolds using a novel design approach. The interior architecture design (IAD) approach seeks to gen...

We study a hierarchical approach for modeling deformable necklaces. A recent paper by Guibas et al. [5] introduced two hierarchies, wrapped and layered. They proved that the wrapped hierarchy admits a separating family of size O(n2−2/d). The main result of this paper is that the same bound holds for the layered hierarchy. The layered hierarchy has some advantages compared with wrapped hierarchy...

The effects of link annotations on user search performance in hypertext environments having deep (layered) and shallow link structures were investigated in this study. Four environments were tested—layered-annotated, layered-unannotated, shallow-annotated, and shallow-unannotated. A single document was divided into 48 sections, and layered and unlayered versions were created. Additional version...

In this article free vibration of a Timoshenko nanobeam with variable cross-section is investigated using nonlocal elasticity theory within the scope of continuum mechanics. Small scale effects are modelled after Eringen’s nonlocal elasticity theory while the non-uniformity is presented by exponentially varying width through the beam length with constant thickness. Analytical solution is achiev...

Multiparty video conferencing is getting increasingly popular on the Internet. However, bandwidth heterogeneity among users still presents an obstacle against delivering a high quality of experience. One natural solution to deal with this heterogeneity is through using layered coding. However, practical layered coders incur significant rate and complexity overheads compared to non-layered codin...

Layered hybrid organic perovskites (HOPs) structures are a class of low-cost two-dimensional materials that exhibit outstanding optical properties, related to dielectric and quantum confinement effects. Whereas modeling and understanding of quantum confinement are well developed for conventional semiconductors, such knowledge is still lacking for 2D HOPs. In this work, concepts of effective mas...

The electromagnetic wave interaction with layered structures constitutes a crucial topic of current interest in theoretical and experimental research. Generally speaking, several modelling and design problems, encountered, for instance, in SAR (Synthetic Aperture Radar) application, GPR (Ground Penetrating Radar) sensing, radar altimeter for planetary exploration, microstrip antennas and MMICs ...
