We take an application of the Kernel Lemma by Kostochka and Yancey [10] to its logical conclusion. The consequence is a sort of magical way to draw conclusions about list coloring (and online list coloring) just from the existence of an independent set incident to many edges. We use this to prove an Ore-degree version of Brooks’ Theorem for online list-coloring. The Ore-degree of an edge xy in ...

-Current network devices enable connectivity between end systems with support for routing with a defined set of protocol software bundled with the hardware. These devices do not support user customization or the introduction of new software applications. Programmable network devices allow for the dynamic downloading of customized programs into network devices allowing for the introduction of ne...

In the article performed an analysis of ore reclaiming and overloading point characteristics at modern opencast mines. Ore reclaiming represents the most effective way of stability support of power-intensive and expensive technological dressing process, and, consequently, of maintenance of the optimal production and set-up parameters of extraction and quality of finished product. The paper prop...

Chromite ores are basically classified on basis of Cr2O3 content and Cr to Fe ratio in a sample. The higher content of Cr increases the value of the ore but this is greatly affected by the presence of impurities in form of silicates, oxides or hydroxides. The present study was performed to analyze the impurities of chromite ore collected from Prangghar (Mohmand agency), Pakistan. From x-ray dif...

We consider a recent security definition of Chenette, Lewi, Weis, and Wu for order-revealing encryption (ORE) and order-preserving encryption (OPE) (FSE 2016). Their definition says that the comparison of two ciphertexts should only leak the index of the most significant bit on which the differ. While their work could achieve ORE with short ciphertexts that expand the plaintext by a factor ≈ 1....

-Current network devices enable connectivity between end systems with support for routing with a defined set of protocol software bundled with the hardware. These devices do not support user customization or the introduction of new software applications. Active networking devices allow for the dynamic downloading of customized programs into network devices allowing for the introduction of new p...

Homogenization is the processing of one type of material so that the inherent fluctuations in respect of quality and/or size distribution are evened out. In blending coal, the aim is to achieve a final product with a well defined composition, from two or more coal types, so that the elements are very well distributed and no large pockets of one type can be identified. In mixing, traces of the i...

The ores of chromite, nickel, copper, and zinc show a wide distribution over geologic time, but those of iron, titanium, lead, uranium, gold, silver, molybdenum, tungsten, and tin are more restricted. Many of the limitations to specific time intervals are probably imposed by the evolving tectonic history of Earth interacting with the effects of the biomass on the evolution of the earth's s surf...

We give necessary and sufficient conditions for a skew polynomial ring K[t; σ, δ] over a division ring K to be a left V -domain. In particular, when this ring admits a unique simple left module, the conditions obtained include: 1) all polynomials are Wedderburn, 2) all n× n matrices over K are (σ, δ)-similar. We also provide necessary and sufficient conditions for this ring to be both left and ...
