For obtaining reservoir petrophysical properties, for example porosity, non-destructive methods such as X-ray computed tomography, CT, seems to be precise and accurate. Porosity is deducted from the CT image with a single scan via different techniques, such as pore space detection by image segmentation techniques then correlation with porosity. More than one hundred samples with carbonate li...

This article introduces Atomic Hypermedia which, unlike traditional hypermedia approaches, does not use the concept of a node. Instead, all content is represented as single character ‘atoms’ which are placed along an arbitrary number of dimensions. This approach addresses some of the issues with node-based hypermedia. The article describes the basic mechanics of Atomic Data Structure, and how h...

Following the coincidence A x atomic year ∼ Earth year (s), (A =Avogardo number, atomic year= aB/αc, aB = Bohr radius, α = fine structure constant, c = light velocity) and considering the ,,niche” for α, i. e. 180 ≤ α ≤ 85, the Ecosphere radius is calculated.

It is demonstrated that the entropy of the ideal mono-atomic gas comprising identical spherical atoms is not conserved under the Planck-Einstein like relativistic temperature transformation, as a result of the change in the number of atomic degrees of freedom. This fact supports the idea that there is no universal relativistic temperature transformation.

The assignment of atomic charges to a regular computational grid and the interpolation of forces from the grid back to the original atomic positions are crucial steps in a multigrid approach to the calculation of molecular forces. For purposes of grid assignment, atomic charges are modeled as truncated Gaussian distributions. The charge assignment and back interpolation methods are currently bo...

UML may be used to describe both the structure and behavior of objectoriented systems using a combination of notations. For the modeling of the dynamic behavior, a number of different models are offered such as interaction, state and activity diagrams. Although compositional techniques for modeling computational processes demand means of composing elements both in non-atomic or atomic ways, UML...

We conduct theoretical studies on the effects of various parameters on generation of multipartite continuous-variable entanglement via atomic spin wave induced by the strong coupling and probe fields in the Λ-type electromagnetically induced transparency configuration in a realistic atomic ensemble by using the Heisenberg-Langevin formalism. It is shown that the increase of the atomic density a...

Realization of distributed quantum systems requires fast generation and long-term storage of quantum states. Ground atomic states enable memories with storage times in the range of a minute, however their relatively weak interactions do not allow fast creation of non-classical collective states. Rydberg atomic systems feature fast preparation of singly excited collective states and their effici...

The distributions of electric charge and magnetism in an atomic nucleus are usually described in terms of multipole moments limited in number by the magnitude of the nuclear angular momentum. In this laboratory, atomic-beam techniques are used to determine such electric and magnetic moments. In addition, information about the radial distribution of nuclear magnetism can be obtained in cases in ...

In this paper, we study the atomic multicast problem, a fundamental abstraction for building fault-tolerant systems. In the atomic multicast problem, the system is divided into non-empty and disjointgroups of processes. Multicast messages may be addressed to any subset of groups, each message pos-sibly being multicast to a different subset. Several papers previously studied this pro...
