A Study on Ganui-Dae’s External Form and Its Modeling for Restoration [PDF]

Journal of Astronomy and Space Sciences, 2013
Ganui-Dae, built in the reign of King Sejong, Joseon Dynasty, is a comprehensive observatory. It has various instruments for observation and time signal such as Ganui, Gyupyo(Gnomon), water-hammering type Honui and Honsang, and so on. Studying on Ganui-

Strong Stability Preserving Runge-Kutta Methods Applied to Water Hammer Problem

Trends in Computational and Applied Mathematics, 2022
The characteristic method of lines is the most used numerical method applied to the water hammer problem. It transforms a system of partial differential equations involving the independent variables time and space in two ordinary differential equations along the characteristics curves and then solve it numerically. This approach, although showing great

Numerical Methods of Visco-elastic Segments on Water Hammer Pressures [PDF]

Numerical Methods in Civil Engineering, 2020
Water hammer is a phenomenon accompanied by damage, vibration and noise. In order to deal with this phenomenon, different solutions have been proposed. Mechanical behavior of pipe material can significantly affect pressure responses of the pipe system during the transient flow.

Spatially resolved texture analysis of Napoleonic War era copper bolts [PDF]

, 2017
The spatial resolution achievable by a time-of-flight neutron strain scanner has been harnessed using a new data analysis methodology (NyRTex) to determine, nondestructively, the spatial variation of crystallographic texture in objects of cultural ...

The technology of Incremental Sheet Forming - a brief review of the history [PDF]

, 2010
This paper describes the history of Incremental Sheet Forming (ISF) focusing on technological developments. These developments are in general protected by patents, so the paper can also be regarded as an overview of ISF patents in addition to a ...

A Simulation Calculation Method of a Water Hammer with Multpoint Collapsing [PDF]

Energies, 2020
The traditional discrete vapor cavity model (DVCM) is widely used in water hammer simulation. Water column separation in pipelines is usually predicted with this model. Nevertheless, the main weaknesses of this model consist of numerical instability and nonconvergence.

Method of Distributions for Water Hammer Equations With Uncertain Parameters [PDF]

Water Resources Research, 2018
AbstractWater hammer equations (WHE) are routinely used to interpret leak detection tests in pipe networks. Assimilation of pressure data into model predictions is typically done within the probabilistic framework, which treats uncertain model parameters (e.g., initial and boundary conditions, location, and intensity of a leak) as random variables so ...

Flux Vector Splitting Method of Weakly Compressible Water Navier-Stokes Equation and Its Application

Water, 2023
Water is a weakly compressible fluid medium. Due to its low compressibility, it is usually assumed that water is an incompressible fluid. However, if there are high-pressure pulse waves in water, the compressibility of the water medium needs to be ...

Digital Rubbing through Physical Simulation: A Non-Invasive Computational Approach for Epigraph Preservation [PDF]

The International Archives of the Photogrammetry, Remote Sensing and Spatial Information Sciences
The preservation of ancient Chinese inscription relics, including oracle bones, steles, and precious metal artifacts, faces critical challenges due to irreversible degradation from environmental erosion and physical contact during documentation.

Narratives of therapeutic art-making in the context of marital breakdown: Older women reflect on a significant mid-life experience [PDF]

, 2008
This paper explores the narratives of three women aged 65-72 years. They reflected on an episode of therapeutic art-making in midlife, which addressed depression associated with marital crisis and breakdown.
