Internet is known to display a highly heterogeneous structure and complex fluctuations in its traffic dynamics. Congestion seems to be an inevitable result of user’s behavior coupled to the network dynamics and it effects should be minimized by choosing appropriate routing strategies. But what are the requirements of routing depth in order to optimize the traffic flow? In this paper we analyse ...

Imposing a thermal and compositional significance to the outcome of the inversion of seismic data facilitates their interpretation. Using long-period seismic waveforms and an inversion approach that includes constraints from mineral physics, we find that lateral variations of temperature can explain a large part of the data in the upper mantle. The additional compositional signature of cratons ...

We made small-angle neutron scattering (SANS) study of a Pluronic L64 micellar system in aqueous solution at high polymer concentrations (wt %), 35%<c<53%, in a temperature range where a kinetic glass transition has been observed by photon correlation spectroscopy and zero shear viscosity measurements. We analyze SANS intensity distributions assuming that the micelles are spherical and interact...

The multidimensional potential-energy “landscape” formalism offers useful insights into the properties of supercooled liquids and glasses. However, its mathematical fundamentals present formidable subtlety and complexity. In the interests of developing a useful approximation for the statistical mechanics of landscapes, we have developed a simple family of models describing the energy-depth dist...

در مطالعه عمیق روی توزیع زاویه ای پاره های شکافت در واکنش یون سنگین ناهمسانگردی های زیادی دیده شده است. این ناهمسانگردی ها را می توان توسط نظریه استاندارد آماری (tsm)(transition statistical state model) توضیح داد.46علت وجود این ناهمسانگردی ها را می توان به اسپین بالا یا z2/a هسته شکافت پذیر نسبت داد1. برای ناهمسانگردیهای بیشترمی -توان از مدل آماری انقطاع (ssm)استفاده کرد. در این مدل توزیع تصویر...

We have accumulated considerable data on the genetic makeup of the Icelandic population by sequencing the whole genomes of 2,636 Icelanders to depth of at least 10X and by chip genotyping 101,584 more. The sequencing was done with Illumina technology. The median sequencing depth was 20X and 909 individuals were sequenced to a depth of at least 30X. We found 20 million single nucleotide polymorp...

[1] Detailed three-dimensional in-situ measurements of deformation at depth are used to examine the rheology of a 6 10 m block of temperate glacier ice. Assuming that the viscosity of this ice is primarily dependent on stress, the relationship between inferred stress and measurements of strain-rate above 115 m depth suggest a constitutive relationship with a stress exponent n 1. Deformation bel...

Prevalence of Agile methods in software companies is increasing dramatically. Software companies need to employ these methods to overcome the inherent challenges of traditional methods. However, transitioning to Agile approach is a topic of debate and there is no unique and well-defined transition model or framework yet. Although some research studies have addressed barriers and strengths behin...

Light fields preserve angular information which can be retargeted to multi-panel depth displays. Due to limited aperture size and constrained spatial-angular sampling of many light field capture systems, the displayed light fields provide only a narrow viewing zone in which parallax views can be supported. In addition, multi-panel displays typically have a reduced number of panels being able to...

Distributed Model Checking avoids the state explosion problem by using the computational resources of parallel environments LTL model checking mainly entails detecting accepting cycles in a state transition graph. The nested depth-rst search algorithm used for this purpose is diicult to parallelize since it is based on the depth-rst search traver-sal order which is inherently sequential. Propos...
