In this work, we apply a principal component analysis (PCA)-based approach combined with look-up tables (LUTs) of corrections to accelerate the VLIDORT radiative transfer (RT) model used in the retrieval of ozone profiles from backscattered ultraviolet (UV) measurements by the Ozone Monitoring Instrument (OMI).
Here, we characterized the pore structure and permeability of natural anhydrite-based cementitious material under various water-anhydrite (W/A) ratios based on the mercury …
Anhydrite can dissolve dangerously so that rapidly accelerating seepage flows occur within a few years unless there are rigorous control procedures. A rational form of site investigation is …
Glassy spheres and anhydrite in the micrometer and submicrometer range of lignite fly ash were analyzed with AEM methods. The main components of the glassy spheres are Al 2 O 3, SiO 2 and CaO. The ratio of Al 2 O 3 (Al 2 O 3 + SiO 2) is constant for most analysis and indicates the origin of the glassy spheres from kaolinite. The calcium content ...
To study the mechanical and cracking modes of anhydrite rock under the freeze–thaw weathering process, the physico-mechanical characteristics and morphology evolutions of anhydrite samples were determined by a series of laboratory tests. Then, a numerical simulation model was established through the PFC2D program, and the types and …
This book is an introduction to the theory of charged particle acceleration. It has two primary roles: 1.A unified, programmed summary of the principles underlying all charged particle accelerators. 2.A reference collection of equations and material essential to accelerator development and beam applications.
studied the tensile strength of the anhydrite intact rock and rock mass through laboratory analysis and eld investigation. Zhang et al. (2019) used Brazilian disc splitting tests to determine the tensile Young's modulus and Poisson's ratio of anhydrite rock. Due to the water–rock expansion and dissolution
Compared with acceleration-based modal analysis, displacement can provide a more reliable and robust identification result for output-only modal analysis of long-span bridges. However, the estimated displacements from acceleration records are frequently unavailable due to unrealistic drifts. Aiming at obtaining more accurate and stable results for determining the …
The paper is organized as follows: In Sec. II, we review the principles and current status of laser wakefield acceleration, sufficient to provide a good understanding of the electron beam properties that govern the production of light sources; in Sec. III, we present four sources produced by laser wakefield accelerated electrons: betatron ...
Due to the beam-pointing and polarization diversities of carrier-mounted elements, it is widely recognized that the principle of pattern multiplication is not applicable to conformal arrays, particularly when coupling effects are considered. This article proposes a near-field Euler rotation-based technique to transform the far-field calculation of arbitrary conformal arrays into the …
If Y t > Y t-1 net investment is positive during period t. On the other hand, if Y t < Y t-1 net investment is negative or there is disinvestment in period t.. Operation of the Acceleration Principle: The working of the acceleration principle is explained in Table I. The table traces changes in total output, capital stock, net investment and gross investment over ten time periods.
In present study, the effect of AS on Portland cement (with anhydrite as setting regulator) setting time, hydration process, hydration product type, pore structure and concrete …
The tetragonal to orthorhombic ferroelastic phase transition between rutile- and ${text{CaCl}}_{2}$-type ${text{SiO}}_{2}$ at high pressures is studied using first-principles …
Swelling of anhydrite rock causes serious damage to the tunnel and generates high additional costs in the process of tunnel construction and operation and has gradually become one of the main factors that threaten the safety of the tunnel. It is extremely difficult to predict swelling pressures and deformations accurately based on conventional swelling constitutive models. …
6.1. Anhydrite Structures Anhydrite structures in this study have the following types: (Figure 6). 6.1.1. Massive Anhydrite Structure This structure consists of masses in the thickness of a few centimeters to one meter. Massive anhydrite has been composed of various textures such as bladed, parallel, felt, equant and fibrous.
The structure parameters of anhydrite crystal were obtained by means of first principles after structure optimization at 0~120 MPa.

The acceleration principle underscores the importance of aligning investment decisions with the trajectory of consumer demand. While businesses aim to capitalize on opportunities for growth and expansion, they must navigate the inherent uncertainties and risks associated with economic cycles and market dynamics.

The principle of superposition [1] is applicable when the mathematical model of the problem to be solved is constituted by a system of equations that are linear and homogeneous in the input and the output variables. In the kinematic analysis of mechanisms, only the velocity analysis of holonomic or first-order non-holonomic mechanisms with time-independent …
The effects of varying Li2CO3 additions on the hydration kinetics of a ternary CSA-OPC-anhydrite system were investigated. The presence of Li led to increased ye'elimite and C3S dissolution as ...
• We know that the radial component of the acceleration of B with respect to O or the acceleration of B, and the radial component of the acceleration of A with respect to B, NOTE: 1) A point at the end of a link which moves with constant angular velocity has no tangential component of acceleration. 2) When a point moves along a straight line,
These clinkers were subsequently mixed with anhydrite and gypsum for comparative analysis. Utilizing a range of analytical techniques such as isothermal calorimetry, X-ray diffraction (XRD), and thermogravimetric analysis (TGA), the early hydration process and the constitution of hydration products were systematically investigated.
