The network architecture is based on the following principles: The network topology is a planar grid of switches that route the traffic according to fixed shortest path (X-Y based) discipline, thus minimizing hardware tables and traffic overheads. Buffer requirements are reduced by employing multi-class wormhole forwarding while allowing inter-class priorities. The layout of the

This paper proposes a new method of image thresholding by using cluster organization from the histogram of an image. A new similarity measure proposed is based on inter-class variance of the clusters to be merged and the intra-class variance of the new merged cluster. Experiments on practical images illustrate the effectiveness of the new method. 2006 Elsevier B.V. All rights reserved.

background: the accuracy and reproducibility of measurements in a locally made three dimensional (3d) simulator was assessed and compared with manual caliper measurements. materials and methods: a total of 20 casts were scanned by our laser scanner. software capabilities included dimensional measurements, transformation and rotation of the cast as a whole, separation and rotation of each tooth ...

the present study aimed at investigating the specific discourse cycles of someintroductory textbooks across disciplines and languages to see to what extent theyacculturate students into the new subjects. to this end, 2 well-established and mostlyused english and persian introductory textbooks in sociology and 2 other wellestablishedenglish and persian introductory textbooks in linguistics were ...

objective: in view of the effect of hard labor on pregnancy outcomes and to determine risk factors, in this study, the effect of spacing between pregnancies was evaluated for probable effect on the incidence of dystocia in labor. materials and methods: this is a cross - sectional study used the records of 210 pregnant women referred to azad university hospitals between january 2000 and december...

automatic road extraction from aerial images can be very helpful in traffic control and vehicle guidance systems. most of the road detection approaches are based on image segmentation algorithms. color-based segmentation is very sensitive to light changes and consequently the change of weather condition affects the recognition rate of road detection systems. in order to reduce the light change ...

Deep neural networks trained using a softmax layer at the top and the cross-entropy loss are ubiquitous tools for image classification. Yet, this does not naturally enforce intra-class similarity nor inter-class margin of the learned deep representations. To simultaneously achieve these two goals, different solutions have been proposed in the literature, such as the pairwise or triplet losses. ...

Marathon runners are ranked in 5-year age groups. However the extent to which 5-year groupings facilitates equitable competition has not been evaluated. The aim of this study was to evaluate the effect of relative age in male and female marathon running. Marathon finishing times for the top ten male (aged 20-69 years) and female athletes (aged 20-64 years) were obtained from the 2013 New York a...

Opportunistic networking, where node mobility is utilized to achieve message delivery, has become an important class of mobile ad hoc networking. A critical component of performance analysis for opportunistic networking is a basic understanding of contact and inter-contact times for commonly studied mobility models. In this paper we give original results nodal contact-times and analytically sho...
