The pore-level two-phase fluids flow mechanism needs to be understood for geological CO2 sequestration as a solution to mitigate anthropogenic emission of carbon dioxide. Capillary pressure at the interface of water–CO2 influences CO2 injectability, capacity, and safety of the storage system. Wettability usually measured by contact angle is always a major uncertainty source among important para...

1 Summary Accurate and cost effective localization is a basic issue in the field of mobile robotics. This work shows how it can be solved by using wireless radio nodes as landmarks. Mechanical scanning is employed at the mobile robot to measure the angle of arrival of radio signals. A measurement integrity check is realized by means of normalized cross correlation. This enables the recognition ...

The aim of this research is the analysis of management ability using accounting and corporate governance criteria and also artificial intelligence. The primary independent variables in this study include regulatory variables (characteristics of corporate governance and audit committee) and accounting variables (performance and risk criteria). We took advantage of Demirjian index to measure mana...

In a previous paper [1] an Euler angle parameterization for SU(4) was given. Here we present the derivation of a generalized Euler angle parameterization for SU(N). The formula for the calculation of the Haar measure for SU(N) as well as its relation to Marinov’s volume formula for SU(N) [2,3] will also be derived. As an example of this parameterization’s usefulness, the density matrix paramete...

S U M M A R Y The principal axis angle ξ 0, or Kagan angle, is a measure of the difference between the orientations of two seismic moment tensors. It is the smallest angle needed to rotate the principal axes of one moment tensor to the corresponding principal axes of the other. This paper is a conceptual review of the main features of ξ 0. We give a concise formula for calculating ξ 0, but our ...

We present an accurate description of the conjugate pair angle-angular momentum in terms of the exponential of the angle instead of the angle itself, which leads to dispersion as a natural measure of resolution. Intelligent states minimizing the uncertainty product under the constraint of a given uncertainty in angle or in angular momentum turn out to be given by Mathieu wave functions. We disc...

In this paper, a kinematic optimal design of a new parallel-type rolling mill based upon Stewart platform manipulator is investigated. The objective of this new parallel-type rolling mill is to permit an integrated control of the strip thickness, strip shape, pair crossing angle, uniform wear of the rolls, and tension of the strip. A manipulability measure, as the ratio of the manipulability el...

scatterometer optimized for near angle measurements. The system relies on a unique beam apodization scheme using gas phase absorption to produce a Gaussian pupil function. Initial results show two orders of magnitude improvement over a previous design employing a uniform pupil function. The background signature is approaching sufficient levels to measure small angle scatter from high quality EU...
