Due to recent developments in concert hall design, there is an increasing interest in the analysis of sound energy decays consisting of multiple exponential decay rates. It has been considered challenging to estimate parameters associated with double-rate (slope) decay characteristics, and even more challenging when the coupled-volume systems contain more than two decay processes. To meet the n...

An 'incremental form' of anisotropic damage constitutive equation is proposed both for brittle and ductile materials. Based on the concept of irreversible thermodynamics that damage processes are history independent coupled with irreversible energy dissipation, two types of definition for damage representation are established, known as damage tensor D and damage strain tensor nd, to describe co...

Pharmaceutical applications of 3D printing technologies are growing rapidly. Among these, vat photopolymerisation (VP) techniques, including Stereolithography (SLA) hold much promise for their potential to deliver personalised medicines on-demand. SLA offers advantageous features pharmaceutical production, such as operating at room temperature and offering an unrivaled resolution. However, sinc...

Complex molecules often have many structures (conformations) of the reactants and the transition states, and these structures may be connected by coupled-mode torsions and pseudorotations; some but not all structures may have hydrogen bonds in the transition state or reagents. A quantitative theory of the reaction rates of complex molecules must take account of these structures, their coupled-m...

This paper discusses a methodology of analyzing the flight dynamic stability of a flapping wing Micro Air Vehicle (MAV) in hover. The flexible flapping wings are modeled by a strain-based geometrically nonlinear beam formulation, coupled with an empirical aerodynamic formulation for load calculation on the wings surfaces. Wing flapping kinematics is described using a set of Euler angles. Nonlin...

Two of the drawbacks of using natural-based composites in industrial applications are thermal instability and water uptake capacity. In this work, mechanical wood pulp was used to reinforce polypropylene at a level of 20 to 50 wt. %. Composites were mixed by means of a Brabender internal mixer for both non-coupled and coupled formulations. Differential scanning calorimetry (DSC) and thermogravi...

in saturated soils, heating induces thermal expansion of both grains and the pore fluid. lower thermal expansion coefficient of aggregates results in the increase of pore pressure and reduction of the effective stress besides subsequent volume changes due to the dissipation of pore pressure and heat transfer. dissipation of thermally induced pore pressure with time is a coupled thermo-hydro-mec...

in this paper, using a one-dimensional simulation model, the reforming process of sour gas, i.e. ch4, co2, and h2s, to the various charged particles and syngas in a dielectric barrier discharge (dbd) reactor is studied. an electric field is applied across the reactor radius, and thus a non-thermal plasma discharge is formed within the reactor. based on the space-time coupled finite element meth...

we consider the coupled system$f(x,y)=g(x,y)=0$,where$$f(x, y)=bs 0 {m_1}   a_k(y)x^{m_1-k}mbox{ and } g(x, y)=bs 0 {m_2} b_k(y)x^{m_2-k}$$with entire functions $a_k(y), b_k(y)$.we    derive a priory estimates  for the sums of the rootsof the considered system andfor the counting function of  roots.

We calculate the tree-level amplitudes for electrically neutral $2\to2$ scattering Standard Model Higgs doublet non-minimally coupled to Ricci scalar. consider both metric and Palatini formulation of gravity. find partial wave unitarity limit a general background field value.
