The ray-based approach is powerful and useful for the description of 3-D images because of its neutrality to all types of 3-D displaying technologies. This approach has been developed in order to reproduce the whole visual data captured at the transmitter. However, for the purpose of augmented reality, not only is the reproduction of real visual data essential, but also the synthesis of virtual...
Plasma waves excited by intense laser beams can be harnessed to produce femtosecond duration bunches of electrons with relativistic energies. The very large electrostatic forces of plasma density wakes trailing behind an intense laser pulse provide field potentials capable of accelerating charged particles to high energies over very short distances, as high as 1GeV in a few millimetres. The sho...
MIWeb realizes a mediator-based integration of heterogeneous metadata sources over the Web. Mediators are well known from database integration. They improve the quality of search results by providing a query language, by automatically coupling sources, and by filtering redundant results. The MIWeb system contributes mediator architectures in the context of Web sources, metadata standards for in...
Although the internet has dramatically changed recruitment practices, many web-based recruitment sources have not yet been investigated. The present study examines the effects of web-based employee testimonials and web-based word-of-mouth (i.e., “word-of-mouse”) on organizational attraction. The source credibility framework is used to compare these company-dependent and company-independent recr...
We present recent advances in multi-wavelength, power-equalized laser sources that incorporate a semiconductor optical amplifier (SOA) and simple optical filters, such as Lyot-type and Fabry-Perot, for comb generation. Both linear and ring-cavity configurations are presented, and single-pass optical feedback technique is proposed to improve the performance in terms of the number of simultaneous...
Background and Objectives : Awareness of the cancer incidence is essential for cancer prevention and control programs. Capture-recapture methods have been recommended for reducing bias and increasing the accuracy of cancer incidence estimation. This study aimed to estimate the incidence of gastric cancer by the capture-recapture method based on Ardabil population-based cancer registry data. ...
The rules of a number of electricity markets encourage renewable energy production and demand response through fixed support schemes and socialize the costs of integrating this production trough grid tariffs. These mechanisms are not economically efficient because they do not rely on market-based prices and do not consider the actual costs of achieving reliable system operation. This paper pres...
We have previously proposed ithography applications. Here we report advances in measurement
It is the common goal of today’s knowledge management systems to bring the right piece of knowledge to the right person at the right time. As soon as documents are involved in this process of information supply, intelligent techniques for information supply from text sources have to be employed. To this end, we propose a profile-based approach. Profiles describe the generic information need of ...
The proliferation of web data sources increasingly demands the integration of these sources. To facilitate the integration process, a pre-analysis step is required to classify and group data sources into their correct domains. In this paper, we propose a feature-based clustering approach for clustering web data sources without any human intervention and based only on features extracted from the...
