Blasting effects of cross‐fault deep‐buried excavation on adjacent existing tunnel stability

open access: yesDeep Underground Science and Engineering, EarlyView.
Based on the theoretical analysis of cylindrical wave propagation in a deep rock mass in the fault with a filling layer, the calculation method of peak particle velocity caused by wave propagation in the existing tunnel is established. The viscoelastic characteristics of a rock mass are examined in the analysis.

WENO Scheme Based on Lax-Wendroff Time Discretization to Solving Hyperbolic Conservation Laws

open access: yesJournal of Harbin University of Science and Technology, 2017
The research of high accuracy and high resolution schemes have been a hot topic in computational mathematics. According to low resolution and large amount of calculation of the original WENO-JS scheme,we propose a simple new limiter fifth order upwind ...

Nonlinear Regularizing Effect for Conservation Laws

open access: yes, 2008
20 pagesInternational audienceCompactness of families of solutions --- or of approximate solutions --- is a feature that distinguishes certain classes of nonlinear hyperbolic equations from the case of linear hyperbolic equations, in space dimension one.

Nonlinear Hyperbolic Conservation Laws. [PDF]

open access: yes, 1987
Abstract : The focus of this research project has been the study of systems of conservation laws that lose strict hyperbolicity. Two areas of application, namely isentropic gas dynamics for a van der Waals gas, and multiphase flow in a porous medium were considered.

Precipitation and tree biomass correlate with the diversity and functional composition of tropical rainforest cricket assemblages across climate and disturbance gradients

open access: yesEcography, EarlyView.
Disturbance‐driven changes in rainforest structure and environmental conditions can alter ecosystem functioning, yet the consequences for invertebrate communities – key contributors to decomposition, herbivory, and trophic interactions – are not fully understood, particularly in relation to structural changes in vegetation.

Seismic Design of Concrete Dams: An Integrated Risk‐Informed Performance‐Based (RIPB) Framework

open access: yesEarthquake Engineering &Structural Dynamics, EarlyView.
ABSTRACT This paper advances the integration of risk‐informed principles into the seismic design of dams—a domain long guided by standards‐based, largely deterministic approaches. While performance‐based earthquake engineering is well established for buildings and bridges, its systematic adoption in dam engineering remains limited. We first address two

Weak asymptotic solution for a non-strictly hyperbolic system of conservation laws-II

open access: yesElectronic Journal of Differential Equations, 2016
In this article we introduce a concept of entropy weak asymptotic solution for a system of conservation laws and construct the same for a prolonged system of conservation laws which is highly non-strictly hyperbolic.

SYSTEMS OF HYPERBOLIC CONSERVATION LAWS WITH MEMORY [PDF]

open access: yesJournal of Hyperbolic Differential Equations, 2007
Global weak solutions of bounded variation to systems of balance laws with non-local source are constructed by the method of vanishing viscosity. Suitable dissipativeness assumptions are imposed on the source terms to assure convergence of the method.

Decentralized Wind Energy Systems as Catalysts for Urban Resilience: A Design Framework

open access: yesEnergy Science &Engineering, EarlyView.
ABSTRACT Confronting the escalating extreme weather events (EWEs) and intensifying winds, this study proposes an active response to these issues by exploring decentralized wind energy production for Peng Chau Island, Hong Kong. It integrates theoretical perspectives on energy democracy—empowering local communities through energy autonomy—and urban ...

Shock Waves in Gas Dynamics [PDF]

open access: yesSurveys in Mathematics and its Applications, 2007
Shock wave theory was studied in literature by many authors. This article presents a survey with references about various topics related to shock waves: Hyperbolic conservation laws, Well-posedness theory, Compactness theory, Shock and reaction-diffusion
