This paper presents a standards-based architecture for a complex and generic distributed multimedia scenario, which combines content search and retrieval, DRM, and context-based content adaptation together. It is an innovative and totally generic approach trying to narrow the semantic-gap by integrating a flexible language for multimedia search based on MPEG Query Format (MPQF) standard with th...

Configuration design deals with the composition of artifacts from a predefined catalog of components over a wide variety of application domains (architecture, telecommunications systems, civil engineering, control software, etc.). Recent years have seen various attempts to work towards a high-level, formal representation of configuration problems with the goal of providing a stable platform on ...

Despite increasing use, little is known about the effectiveness of web-based instructional supplements. This study assess the effectiveness of on-line materials in principles of economics courses. We have collected data on 66 students from three principles sections that describe demographic characteristics and performance and reflect the intensity of use of web-based material. We use this data ...

We discuss the relation between the dimension of a CGA and its primitive part and apply it to deduce a lower bound for the number of all Vassiliev invariants.

numerous advantages are derived from the electronic health record (ehr).though achieving such advantages depends on its architecture, at present no unique understanding of the architecture dimensions and specifications is available. therefore, the aim of the present study is a systematic review of architecture perception of the electronic health record. the authors searched the literature in sc...

to study the effect of salinity stress on some physiological attributes of four grape cultivars in vineyards of urmia in iran, an experiment was carried out as factorial arrangement in randomized complete block design with four replications. experimental factors included: grape cultivars qazel ozum, qareh shireh, tabrzeh and dizmari, and salt concentrations 0, 25, 50 and 100 mmol l-1 and locati...

In the current Internet, more and more providers are developing and deploying their own Content Delivery Networks in order to improve the Quality of Experience and decrease the load within their networks. An interesting scenario would be to interconnect these networks to cooperate between these different Content Delivery Networks. The IETF Content Delivery Network Interconnection Working Group ...

A new method for simultaneous and independent on-line determination of bulk density and moisture content in particulate materials by measurements of the relative complex permittivity is proposed. The bulk density is determined, based on a representation in the complex plane of relative complex permittivity normalized to bulk density. For moisture content determination, a new density-independent...

An approach is presented in this paper for determination of the semantic content of a composit concept, based on applying a set of operators, which operate on the values of certain attributes in the initial concepts. The approach is capable of telling the user in what way the drawbacks of one concept can be moderated via employing the other concept. The proposed approach to idea generation can ...
