The problem of optimal winner determination in combinatorial auctions consists of finding the set of bids that maximize the revenue for the sellers. Various solutions exist for solving this problem but they are all centralized. That is, they assume that all bids are sent to a centralized auctioneer who then determines the winning set of bids. In this paper we introduce the problem of distribute...

with the aim of a determination of physical properties of date palm male flowers, as well as optimum flower detachment conditions, this study was carried out in two parts. in the first part of the study, the palm groves of khuzestan province were totally surveyed. “ghanami” cultivar was in the end selected to be studied as the superior cultivar in the region. drying up of the male flowers at 70...

Distributed search is an effective way to search information over thousands of information collections available on the web. As an important feature in distributed search, collection size plays a vital role in resource representation and selection. This paper proposes two novel algorithms to estimate collection size in uncooperative environments. Sample high frequent resample (SHFRS) algorithm ...

Due to the tremendous increase rate and the high change frequency of Web documents, maintaining an up-to-date index for searching purposes (search engines) is becoming a challenge. The traditional crawling methods are no longer able to catch up with the constantly updating and growing Web. Realizing the problem, in this paper we suggest an alternative distributed crawling method with the use of...

This paper presents results of a work on crawling CEUR Workshop proceedings web site to a Linked Open Data (LOD) dataset in the framework of Semantic Publishing Challenge 2014. Our approach is based on so-called “templates of web site’ blocks“ and DBpedia for crawling and linking extracted entities.

The study of quadrupeds has furnished most of our understanding of mammalian locomotion. To allow a more direct comparison of coordination between the four limbs in humans and quadrupeds, we studied crawling in the human, a behavior that is part of normal human development and mechanically more similar to quadrupedal locomotion than is bipedal walking. Interlimb coordination during hands-and-kn...

The crawling wave experiment, in which two harmonic sources oscillate at different but nearby frequencies, is a development in sonoelastography that allows real-time imaging of propagating shear wave interference patterns. Previously the crawling wave speed was recovered and used as an indicator of shear stiffness; however, it is shown in this paper that the crawling wave speed image can have a...
