The workshop was opened with welcoming remarks by Mr. Ulrich Mohr, Head of Section, International Policy on Telecommunications and Posts, BMWI, and Mr. Sam Paltridge of Information, Computer, and Communications Policy Division, OECD. Both speakers introduced general issues in relation to Internet traffic exchange and a summary of recent discussions in OECD on this subject. Mr. Paltridge noted r...

A new contact bond model based on the Mohr-Coulomb failure criterion has been implemented in PFC2D to reproduce the behaviour of frictional cohesive (c, φ) geomaterials. According to this model, the bond strength can be clearly divided into two distinct micromechanical contributions: an intergranular friction angle and a cohesive bond force. A parametric analysis has been run to validate the pr...

We present an arc-consistency algorithm NAC4 to account for some types of non-binary constraints. It di ers from the generalized algorithm GAC4 [ Mohr and Masini, 1988 ] as the constraints need not be modeled as explicit relations but can be retained as implicit n-ary relations. The advantage of this algorithm over GAC4 is pronounced when the checking of constraints is expensive. By an ordering...

We study here the well-known propagation rules for Boolean constraints. First we propose a simple notion of completeness for sets of such rules and establish a completeness result. Then we show an equivalence in an appropriate sense between Boolean constraint propagation and unit propagation, a form of resolution for propositional logic. Subsequently we characterize one set of such rules by mea...

With the SIFT and SURF based recognition, the paper presents the impact of salient features in object recognition. We use the two well-known image descriptors in the bag of words framework on five online available standard datasets. Experiments show that by introducing saliency in the bag of words model, state-of-the-art performance can still be retained while reducing considerable amount of da...

Multiple Sclerosis (MS) is a debilitating, chronic and degenerative neurological disease where demyelination of the central nervous system (CNS) occurs and causes lesions in the axons of the nerves (McCabe 2005; Mohr et al. 1999). MS is a serious disease which occurs worldwide. The prevalence and incidence rates worldwide for MS are estimated at 30 per 100 000 and 2.5 per 100 000 respectively (...

Web crawlers today suffer from poor navigation techniques which reduce their scalability while crawling the World Wide Web (WWW). In this paper we present a web crawler named Tarantula that is scalable and fully configurable. The work on Tarantula project was started with the aim of making a simple, elegant and yet an efficient Web Crawler offering better crawling strategies while walking throu...

This paper explores the fracture process based on finite element simulation. Both probabilistic and deterministic methods are employed to model crack initiation, and several commonly used criteria are utilized to predict crack growth. It is concluded that the criteria of maximum tensile stress, maximum normal stress, and maximum Mises stress, as well as the Coulomb-Mohr criterion are able to pr...

The origins of the syndrome dated back to the discoveries of the lupus anticoagulant by Conley and Hartmann in 1953, recognition of the association between the Biological False Positive Test for Syphilis (BFP-STS) and autoimmune diseases by Moore and Mohr in the 1950s. Subsequent investigators recognized over the next two decades that many patients with the lupus anticoagulant frequently had BF...

Microtubule (MT) dynamic instability is driven by GTP hydrolysis and regulated by microtubule-associated proteins, including the plus-end tracking end-binding protein (EB) family. We report six cryo-electron microscopy (cryo-EM) structures of MTs, at 3.5 Å or better resolution, bound to GMPCPP, GTPγS, or GDP, either decorated with kinesin motor domain after polymerization or copolymerized with ...
