Human speech understanding works incrementally. We begin to process acoustic input before the speaker's utterance has ended. A system capable of performing sophisticated communication in a natural dialogue or simultaneous interpreting, has to work incrementally, too. The architecture of such a system should be modular, uniform and integrated. We present an architectural framework that suits the...

In various domain specific applications with heterogeneous databases, an ontologydriven approach to data integration relies on the alignment of the concepts of a global ontology that describes the domain, with the concepts of the ontologies that describe the data in the local databases. Once the alignment between the global ontology and each local ontology is established, agreements that encode...

Software engineers create alternative designs for their programs, develop these designs to various degrees, compare their properties, then choose among them. Yet most software environments do not allo.oJ alternative definitions of procedures to exist simultaneously. It is our hypothesis that an explicit representation for alternative designs can substantially improve a programmer's ability to d...

Layered multicast is a scalable solution to data dissemination over the Internet. The performance of layered multicast hinges upon the transmission schedule. In this paper, we study the scheduling problem in the layered multicast context. This work generalizes the extensively studied multicast scheduling problem (layered and non-layered) by introducing simultaneously the data popularity and the...

The oxygen evolution reaction is a key reaction in water splitting. The common approach in the development of oxygen evolution catalysts is to search for catalytic materials with new and optimized chemical compositions and structures. Here we report an orthogonal approach to improve the activity of catalysts without alternating their compositions or structures. Specifically, liquid phase exfoli...

The challenge of ontology-driven modelling of information components is well known in both academia and industry. In this paper, we present a novel approach to deal with customisation and abstraction of ontology-based model evolution. As a result of an empirical study, we identify a layered change operator framework based on the granularity, domain-specificity and abstraction of changes. The im...

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...
